The options are: - -DEBUG (origin: U C Berkeley) - enables the -d command line option, and allows SIGUSR1 to increment -and SIGUSR2 to clear the internal variable "debug", which in turn controls -hundreds of fprintf()'s out to /usr/tmp/named.run. - you probably want this. it makes the binary bigger but not slower (or -at least not much slower), but SIGUSR[12] are the only way you'll track down -misconfigured name servers that hose you down with billions of bogus requests. - you may need this, it is on by default. - -ALLOW_T_UNSPEC (origin: MIT Project Athena) - enables the "unspec" RR type for ancient Athena software that does not -know about TXT RR's. - you probably do not care about this, it is off by default. - -ALLOW_UPDATES (origin: Mike Schwartz, University of Washington) - enables "dynamic updates", described in "doc/DynamicUpdate". this lets -you update named's in-memory database on the fly if you have the right client. -there is absolutely no security around this; if you enable it, anyone who can -reach your server can update your database. - this code doesn't compile any more and will be removed shortly. - -INVQ (origin: U C Berkeley, with #ifdef's by Paul Vixie) - enables "inverse queries", which in all of the internet only one -client ever uses: ancient nslookup. if you build named with INVQ defined, -you get the time-honored behaviour of supporting this whole class of queries -for no real purpose other than to waste a few hundred kilobytes of your -memory and about 3% of named's total CPU time. if you build with INVQ -undefined, old nslookups will not be able to reach your server in their -startup phase, and you will have to use the "server" command after it fails -over to some other server, or use "nslookup - 0" to get in from the shell. - if you need to support old nslookups try "options fake-iquery" -instead of enabling this option. - you probably do not want this. - -DSTORAGE (origin: U C Berkeley, with #ifdef's by Paul Vixie) - enables a malloc-debugger that checks for overruns on both ends of -each allocated block of memory. used when debugging since C has no bounds -or type checking. - you probably do not want this, it is off by default. - -DMALLOC (origin: Paul Vixie of Digital) - enables a malloc-debugger that traces all allocated blocks of memory -such that SIGIOT's output (see STATS option) includes a list of all mallocs -in the program, how many times each has been called, how many blocks of memory -allocated by that malloc are not yet free, and how many bytes they use up. -under each one will be a list of each free/realloc that has deallocated a block -of that malloc's memory, and how many times it has done so. - this is extremely helpful for finding memory leaks. as such, you -probably do not want this unless you are debugging named. - you probably do not need this, it is off by default. - -XFRNETS (origin: Paul Vixie of Digital) - enables the "xfrnets" command in named.boot. this has the same -syntax as "forwarders" and "sortlist" -- that is, a list of dotted quads. -each one is a network (16.0.0.0 and 130.180.0.0 are examples) or a host. -if you put any xfrnets commands into your named.boot, then zone transfers -will only be honored if they come from inside one of the specified -networks. this is very useful if you want to keep people outside from -being able to trivially map your entire network, but it doesn't stop them -from iterating so it's more annoying than secure. - this feature was once called "tcplist" out of ignorance on my part, -but with advice from phil almquist i decided to rename it "xfrnets" and make -it only control zone transfers -- previously it controlled all TCP connections -which made certain TCP-only resolvers unable to use our servers. the "tcplist" -syntax still works; it is a synonym for "xfrnets". - it is also nice if you want to keep the outside world from making your -nameserver fork and swap trying to do unauthorized zone transfers. if you have -large zone files or use BIND for TXT records you will find this useful. - you probably want this, it is on by default. - -PID_FIX (origin: Don Lewis of Harris) - tells named that if it starts up but can't keep going because another -nameserver is already running (and sitting on the server port), it should -put the /etc/named.pid (/var/run/named.pid) file back the way it found it. - you probably want this, it is on by default. - -FWD_LOOP (origin: Don Lewis of Harris) - tells named that if you list any of your own IP addresses in a -"forwarders" command in your named.boot file, you should be scolded. - you probably want this, it is on by default. - -NO_GLUE (origin: Don Lewis of Harris, and Andrew Partan of UUNET) - tells named-xfer that incoming zone transfers should be checked -for "glue" that comes from a zone outside the zone being transfered, and -comment this garbage out in the zone file so that when named reads in the -zone file after named-xfer exits, the garbage will not be entered into the -memory-resident database. - also tells named that when it is performing an outgoing zone -transfer, it should not send any of these "glue" records. - you definitely want this, it is on by default. - -BOGUSNS (origin: Piet Beertema of EUNet) - enables the "bogusns" command in named.boot. this has the same -syntax as forwarders and sortlist. any NS RR's that come in whose addresses -are on the list of "bogusns" addresses will be ignored. this is the last -resort when someone is bogusly advertising themselves as a root server. - just in case, though you won't use it often. - you probably want this, it is on by default. - -QRYLOG (origin: Bryan Beecher of UMich) - enables "query logging", such that SIGWINCH toggles tracing of all -incoming queries. the trace is sent to syslog, and is huge, but when you -need this you will need it bad and it does not slow named down or make it -larger. - If you define QRYLOG you may also start up named in query logging -mode by using the -q flag. If you do so you will probably want to analyze -the logs produced, the dnsstats and lamers scrips (in the contrib/umich -and contrib/lamers directories) will do it for you. - you probably want this, it is on by default. - -LOGFAC (origin: various people) - If you start up named with the -q flag you will be logging -large amounts of data, and probably will not want them logged to the -default logging facility, which is LOG_DAEMON. You will want to -redefine LOGFAC, presumably to LOC_LOCALn (0 <= n <= 7). Remember to -modify /etc/syslog.conf appropriately. - This only works on a system with a modern syslogd. - as such, it is on by default. - -YPKLUDGE (origin: Piet Beertema of EUNet) - certain versions of NIS/YP are capable of using the DNS for names -that cannot be found in the YP servers. of these, certain versions can't -tell the difference between a dotted quad and a domain name, and they send -queries to the DNS for dotted quads as if they were domain names. if your -named does not do anything special with these queries, they will end up -getting forwarded to other servers, effectively hosing all of you down with -endless useless network traffic. YPKLUDGE enables some checking in named -that lets it catch these bogus queries and send back immediate errors. - If you run "ypserv -i" you definitely want this, as a malconfigured -NIS server can cause DNS "flood" queries otherwise. Trust me. - this is off by default. - -TRACEROOT (origin: pma@cnd.hp.com and Bryan Beecher of UMich) - enables some checking in named for bogus root nameservers. This -code has been in use at U-M for years, so it is pretty well tested, plus we -have never been burned by the "bogus root NS scares" that have plagued the -DNS off and on. - this feature people will very much want to use, it is on by default. - -LOCALDOM (origin: Berkeley) - if set, the "domain" directive is recognized in the named.boot file. -this causes us to retry queries with the specified domain appended to the -name if the first lookup fails. this is a very bad idea since a given name -server will often be used by clients in more than one domain -- a name server -should _not_ make any presumptions as to the "home domain" of a requestor. - you almost certainly do not want this, it is off by default. - -SLAVE_FORWARD (origin: pma@sdd.hp.com) - if set, "slave" servers behave in an arguably more-correct way. this -is an experimental addition to BIND 4.9 that causes slaves to time out queries -in 60/N seconds where N is the number of forwarders defined. previously a -query would time out almost immediately, which caused a lot of unnecessary -network traffic. - you probably want this, it is on by default. - -FORCED_RELOAD (origin: pma@sdd.hp.com) - if set, then when a HUP signal is received, all secondary zones are -scheduled for serial-number comparison with the primaries. this has the effect -that if you HUP your server, it will refresh any zones which have changed, -even if those zones' refresh times have not been reached. - you probably want this, it is on by default. - -WANT_PIDFILE (origin: berkeley, parameterized by arc@sgi) - if set, a file called named.pid will be created in /etc or /var/run -when the name server has started. this file can be used to send signals to -BIND, as in "kill -HUP `cat /etc/named.pid`". - unless you are only on an SGI (where killall(1M) makes the pid file -unnecessary); - you probably want this, it is on by default. - -DOTTED_SERIAL (origin: berkeley; parameterized by vixie) - if set, allows a somewhat arcane n.m syntax in the serial number -field of an SOA. this is officially deprecated for 4.9; you should use -straight integer values and find an encoding that does not depend on -scaled-integer pseudodecimals. i suggest YYYYMMDDnn where YYYY is the -four-digit year, MM is the two-digit month, DD is the two-digit day-of-month, -and nn is a daily version number in case you change your serial number more -than once in a day. this encoding will overflow in the year 4294 gregorian. - you almost certainly do not want this, but if you have old zone files -lying around and you don't want to think your way through converting their -serial numbers, this deprecated behaviour is available. - graciously, it is on by default. - -SENSIBLE_DOTS (origin: kagotani@cs.titech.ac.jp; parameterized by vixie) - if set, changes the semantics of an "n.m" serial number from - n*10^(3+int(0.9+log10(m))) + m -to - n*10000+m - if you are using DOTTED_SERIAL in spite of its deprecated status, -and you are interested in a more predictable and sensible interpretation of -dotted numbers, then you probably want this. - it is off by default. - -VALIDATE (origin: USC/ISI) - enables a validation procedure to provide some security in an -otherwise insecure environment. Any RRs are accepted from a server only if -the server is authoritative over that domain. We consider a server -authoritative (for validation purposes) for even the sub-domains that it has -delegated to others. RRs are validated against the data we have in cache -already. Invalid records are neither cached nor returned. - it is off by default because it is hopeless, and the code will all -be ripped out of BIND in the near future. - -NCACHE (origin: USC/ISI) - enables negative caching. We cache only authoritative NXDOMAIN or -authoritative NOERROR with zero RR count. Non-authoritative NXDOMAIN answers -now contain NS records in the authority section. Non-authoritative NOERROR -responses have no authority or additional records to differentiate them from -referrals. They are cached for NTTL secs (currently 10 minutes) and are timed -out when the ttl expires. - you probably want this, it is on by default. - -RESOLVSORT (origin: marka@syd.dms.csiro.au) - enable sorting of addresses returned by gethostbyname. Sorting order -is specified by address/netmask pairs. This enables a host to override the -sortlist specified in the nameserver. - you probably want this, it is on by default. - -STUBS (origin: marka@syd.dms.csiro.au) - enable transfer and loading of NS records only for a zone. -still experimental. it won't hurt to enable it, but it may not work perfectly -so using it could lead to some confusion. - you probably don't care, it is on by default. - -SUNSECURITY (origin: rossc@ucc.su.oz.au) - enable checking of PTR records in gethostbyaddr() to detect -spoofing. Forced on SunOS 4 shared library as rlogin etc. depend on this. - you should probably not set this by hand. - -SECURE_ZONES (origin: gshapiro@guest.wpi.edu) - enables support for secure zones. This restricts access to -information in the zone according to the information found in the -secure_zone TXT RR found in the zone. If none is found, the zone is -world-readable. For information on the format of the secure_zone TXT -RR, see the Name Server Operations Guide for BIND. - you probably want this, it is on by default. - -ROUND_ROBIN (origin: Marshall Rose of TPC.INT) - if set, causes the databuf list in a namebuf to be rotated by one -slot after each access to it. this has the effect that if multiple RR's -of a given type are present, they will be given in "round robin" order -instead of always being given in the same order. - you probably want this, it is on by default. - -ADDAUTH (origin: marka@syd.dms.csiro.au) - if set, cause NS and glue A records to be returned with authoritative -answers. this causes slightly larger replies but less DNS traffic overall. - unless you have Mac's with an older version of Mac/TCP; - you probably want this, it is on by default. - -RFC1535 (origin: paul@vix.com) - if set, the resolver's default "search" list will be just the entire -"domain" name rather than the sliding window it had before 4.9.2. this will -make the default search list shorter, so folks who are saying "domain a.b.c" -and relying on the implicit "search a.b.c a.b c" will miss "a.b" and "c". - this option is on for compatibility with RFC 1535. - you should NOT turn it off, it is on by default. - -GEN_AXFR (origin: mark@comp.vuw.ac.nz, tytso@ATHENA.MIT.EDU, gdmr@dcs.ed.ac.uk) - if set, allows specification of zones in classes other than "IN" in -the named.boot file. Allows an optional "/class" on the "primary" and -"secondary" directives. Also fixes zone transfers so only data in the class -requested is transfered. - you probably want this, it is on by default. - -DATUMREFCNT (origin: mark andrews) - you want this. it will not be optional in future releases. - -LAME_DELEGATION (origin: don lewis; reworked by bryan beecher and don lewis) - this will detect the condition where some other server has told you -that a given set of servers is authoritative for some domain, and at least -one of those "delegated" servers disagrees (i.e., answers non-authoritatively). - you probably want this, it is on by default. - -LAME_LOGGING (origin: don lewis) - enable logging of lame delegations and set the log level - you may want this, it is on by default. - -RETURNSOA (origin: mark andrews) - This allows negative caching to work. Without this, older -pre-4.9.3 nameservers will not accept -ve cached anwsers. We actually -store the SOA record from the authority section rather that what was -requested because it is the existence of the NXDOMAIN that matters not -the type of data. The zone of the SOA record is tagged to the end of -the SOA record to allow it to be reconstructed. - You probably DO NOT WANT THIS, it's experimental and dangerous. - it is off by default. - -CLEANCACHE (origin: mark andrews) - Bind consumes memory without bound without this option. This -patch allows bind to periodically remove any stale entries in the -cache. Bind's memory usage should stabilize after approximately 1 day of -operation, as most TTL's are <= 1 day. Without this option stale entries -are only removed when they are looked up. - You probably want this, it is on by default. - -PURGE_ZONE (origin: mark andrews) - Various junk below a zone tends to hang around and corrupt future -zone data if a zone grows deeper. PURGE_ZONE will remove all traces of or -data which could be part of zone before loading a new one. - You probably want this, it is on by default. - -STATS (origin: Paul Vixie) - Named's internal statistics can take a fair amount of memory and -if you aren't interested in looking at these numbers you should disable -the feature. Future versions may require this. - You probably want this, it is on by default. - -RENICE (origin: bp@deins.informatik.uni-dortmund.de) - if set, the process priority of the AXFR subprocesses is changed to -"normal". If you are planning to raise the priority of the main nameserver -process, you will use this. - You probably want this, it is on by default. - -GETSER_LOGGING (origin: Paul Vixie) - if set, errors that occur during the fetch of serial numbers for zone -transfer consideration will be syslog()'d. this can lead to a lot of logging, -but is very helpful if you don't know why a zone isn't transfering. - You may not want this, but it is on by default. - -SHORT_FNAMES (origin: pma@sdd.hp.com) - on systems whose file names can only be 14 characters long, the temp -files created by named-xfer need to be constructed somewhat differently. this -should probably become the default since it is harmless. - you probably don't care one way or the other, it is off by default. - -XSTATS (origin: Benoit.Grange@inria.fr) - if set, the name server keeps more STATS about requests -received, and logs to syslog total counters from time to time. If you -aren't interested in looking at these numbers you should not enable -the feature. Requires STATS. - You may want this, but it is off by default. - -BIND_NOTIFY (origin: paul@vix.com) - experimental at this time; an internet draft is circulating. this -option informs slaves ("secondary" servers in BIND's erroneous terminology) -instantly when the master (primary, or another slave) loads a new zone. it -works fine and seems to cause no problems with slaves that don't support it, -but it does not implement the current internet draft (it lacks some necessary -delays) and causes a lot of extra syslog traffic, especially at startup. if -you don't mind running code that will absolutely NOT be compatible with the -eventual standard when the RFC is released, go ahead and turn this on. - vendors should not enable this in versions shipped to customers. - You will want this when it becomes compliant, it is off by default. - -LOC_RR (origin: ckd@kei.com) - incorporates support for the (RFC 1876) LOC RR type. - You may want this, it is on by default. - -SORT_RESPONSE (legacy) - should responses be sorted in what the server considers an optimal -order for the client? this is on by default but it does very little good. - -## ++Copyright++ 1989 -## - -## Copyright (c) 1989 -## The Regents of the University of California.

The support is not optional, since its presence ought not to -affect anyone who does not go looking for it. The support includes: - - inet_ntop() new function. - inet_pton() new function. - RES_USE_INET6 causes gethostby*() to return either real IPv6 - addresses (if available) or mapped (::FFFF:a.b.c.d) - addresses if only IPv4 address records are found. - gethostbyname() can search for T_AAAA in preference to T_A. - gethostbyaddr() can search in IP6.INT for PTR RR's. - named can load, transfer, cache, and dump T_AAAA RRs. - - *** Some notes on the new functions *** - -The inet_pton() and inet_ntop() functions differ from the current (as of -this writing) IPv6 BSD API draft. Discussions were held, primarily between -myself and Rich Stevens, on the ipng@sunroof.eng.sun.com mailing list, and -the BIND definitions of these functions are likely to go into the next draft. -(If not, and BIND has to change its definitions of these functions, then you -will know why I chose not to document them yet!) - -These functions can return error values, and as such the process of porting -code that used inet_aton() to use inet_pton() is not just syntactic. Not all -nonzero values indicate success; consider "-1". Likewise, inet_ntoa() is not -just smaller than inet_ntop() -- it's a whole new approach. Inet_ntop() does -not return a static pointer, the caller has to supply a sized buffer. Also, -inet_ntop() can return NULL, so you should only printf() the result if you -have verified that your arguments will be seen as error free. - -The inet_pton() function is much pickier about its input format than the old -inet_aton() function has been. You can't abbreviate 10.0.0.53 as 10.53 any -more. Hexadecimal isn't accepted. You have to supply four decimal numeric -strings, each of whose value is within the range from 0 to 255. No spaces -are allowed either before, after, or within an address. If you need the older -functionality with all the shortcuts and exceptions, continue using inet_aton() -for your IPv4 address parsing needs. - - *** Some notes on RES_USE_INET6 *** - -You can set this by modifying _res.options after calling res_init(), or you -can turn it on globally by setting "options inet6" in /etc/resolv.conf. This -latter option ought to be used carefully, since _all_ applications will then -receive IPv6 style h_addr_list's from their gethostby*() calls. Once you know -that every application on your system can cope with IPv6 addressing, it is safe -and reasonable to turn on the global option. Otherwise, don't do it. - - *** Some notes on mapped IPv4 addresses *** - -There are two IPv6 prefixes set aside for IPv4 address encapsulation. See -RFC 1884 for a detailed explaination. The ::a.b.c.d form is used for -tunnelling, which means wrapping an IPv4 header around IPv6 packets and using -the existing IPv4 routing infrastructure to reach what are actually IPv6 -endpoints. The ::FFFF:a.b.c.d form can be used on dual-stack (IPv4 and IPv6) -hosts to signal a predominantly IPv6 stack that it should use ``native'' IPv4 -to reach a given destination, even though the socket's address family is -AF_INET6. - -BIND supports both of these address forms, to the extent that inet_pton() will -parse them, inet_ntop() will generate them, gethostby*() will map IPv4 into -IPv6 if the RES_USE_INET6 option is set, and gethostbyaddr() will search the -IN-ADDR.ARPA domain rather than the IP6.INT domain when it needs a PTR RR. -This last bit of behaviour is still under discussion and it's not clear that -tunnelled addresses should be mapped using IN-ADDR.ARPA. In other words, this -bit of behaviour may change in a subsequent BIND release. So now you know -another reason why none of this stuff is ``officially'' documented. diff --git a/contrib/bind/man/Makefile b/contrib/bind/man/Makefile deleted file mode 100644 index 26c6af5f12a2..000000000000 --- a/contrib/bind/man/Makefile +++ /dev/null @@ -1,451 +0,0 @@ -# -# Makefile to install the BIND 4.9 manual entries. -# -# Default Configuration: -# There are a set of default assignments immediately following this -# note.

All query options are -accessible from the command line. -.PP -The usual simple use of \fIdig\fP will take the form: -.sp 1 - dig @server domain query-type query-class -.sp 1 -where: -.IP \fIserver\fP -may be either a domain name or a dot-notation -Internet address. If this optional field is omitted, \fIdig\fP -will attempt to use the default name server for your machine. -.sp 1 -\fBNote:\fP If a domain name is specified, this will be resolved -using the domain name system resolver (i.e., BIND). If your -system does not support DNS, you may \fIhave\fP to specify a -dot-notation address. Alternatively, if there is a server -at your disposal somewhere, all that is required is that -/etc/resolv.conf be present and indicate where the default -name servers reside, so that \fIserver\fP itself can be -resolved. See -.IR resolver (@FORMAT_EXT@) -for information on /etc/resolv.conf. -(WARNING: Changing /etc/resolv.conf will affect -the standard resolver library and potentially several -programs which use it.) As an option, the user may set the -environment variable LOCALRES to name a file which is to -be used instead of /etc/resolv.conf (LOCALRES is specific -to the \fIdig\fP resolver and not referenced by the standard -resolver). If the LOCALRES variable is not set or the file -is not readable then /etc/resolv.conf will be used. -.IP \fIdomain\fP -is the domain name for which you are requesting information. -See OPTIONS [-x] for convenient way to specify inverse address -query. -.IP \fIquery-type\fP -is the type of information (DNS query type) that -you are requesting. If omitted, the default is "a" (T_A = address). -The following types are recognized: -.sp 1 -.ta \w'hinfoXX'u +\w'T_HINFOXX'u -.nf -a T_A network address -any T_ANY all/any information about specified domain -mx T_MX mail exchanger for the domain -ns T_NS name servers -soa T_SOA zone of authority record -hinfo T_HINFO host information -axfr T_AXFR zone transfer - (must ask an authoritative server) -txt T_TXT arbitrary number of strings -.fi -.sp 1 -(See RFC 1035 for the complete list.) -.IP \fIquery-class\fP -is the network class requested in the query. If -omitted, the default is "in" (C_IN = Internet). -The following classes are recognized: -.sp 1 -.ta \w'hinfoXX'u +\w'T_HINFOXX'u -.nf -in C_IN Internet class domain -any C_ANY all/any class information -.fi -.sp 1 -(See RFC 1035 for the complete list.) -.sp 1 -\fBNote:\fP -"Any" can be used to specify a class and/or a type of -query. \fIDig\fP will parse the first occurrence of "any" -to mean query-type = T_ANY. To specify query-class = -C_ANY you must either specify "any" twice, or set -query-class using "\-c" option (see below). -.SH OTHER OPTIONS -.IP "%ignored-comment" -"%" is used to included an argument that is simply not -parsed. This may be useful if running \fIdig\fP in batch -mode. Instead of resolving every @server-domain-name in -a list of queries, you can avoid the overhead of doing -so, and still have the domain name on the command line -as a reference. Example: -.sp 1 - dig @128.9.0.32 %venera.isi.edu mx isi.edu -.sp 1 -.IP "\-<dig option>" -"\-" is used to specify an option which effects the -operation of \fIdig\fP. The following options are currently -available (although not guaranteed to be useful): -.RS -.IP "\-x \fIdot-notation-address\fP" -Convenient form to specify inverse address mapping. -Instead of "dig 32.0.9.128.in-addr.arpa" one can -simply "dig -x 128.9.0.32". -.IP "\-f \fIfile\fP" -File for \fIdig\fP batch mode. The file contains a list -of query specifications (\fIdig\fP command lines) which -are to be executed successively. Lines beginning -with ';', '#', or '\\n' are ignored. Other options -may still appear on command line, and will be in -effect for each batch query. -.IP "\-T \fItime\fP" -Time in seconds between start of successive -queries when running in batch mode. Can be used -to keep two or more batch \fIdig\fP commands running -roughly in sync. Default is zero. -.IP "\-p \fIport\fP" -Port number. Query a name server listening to a -non-standard port number. Default is 53. -.IP "\-P[\fIping-string\fP]" -After query returns, execute a -.IR ping (@SYS_OPS_EXT@) -command -for response time comparison. This rather -inelegantly makes a call to the shell. The last -three lines of statistics is printed for the -command: -.sp 1 - ping \-s server_name 56 3 -.sp 1 -If the optional "ping string" is present, it -replaces "ping \-s" in the shell command. -.IP "\-t \fIquery-type\fP" -Specify type of query. May specify either an -integer value to be included in the type field -or use the abbreviated mnemonic as discussed -above (i.e., mx = T_MX). -.IP "\-c \fIquery-class\fP" -Specify class of query. May specify either an -integer value to be included in the class field -or use the abbreviated mnemonic as discussed -above (i.e., in = C_IN). -.IP "\-envsav" -This flag specifies that the \fIdig\fP environment -(defaults, print options, etc.), after -all of the arguments are parsed, should be saved -to a file to become the default environment. -Useful if you do not like the standard set of -defaults and do not desire to include a -large number of options each time \fIdig\fP is used. -The environment consists of resolver state -variable flags, timeout, and retries as well as -the flags detailing \fIdig\fP output (see below). -If the shell environment variable LOCALDEF is set -to the name of a file, this is where the default -\fIdig\fP environment is saved. If not, the file -"DiG.env" is created in the current working directory. -.sp 1 -\fBNote:\fP LOCALDEF is specific to the \fIdig\fP resolver, -and will not affect operation of the standard -resolver library. -.sp 1 -Each time \fIdig\fP is executed, it looks for "./DiG.env" -or the file specified by the shell environment variable -LOCALDEF. If such file exists and is readable, then the -environment is restored from this file -before any arguments are parsed. -.IP "\-envset" -This flag only affects -batch query runs. When "\-envset" is -specified on a line in a \fIdig\fP batch file, -the \fIdig\fP environment after the arguments are parsed, -becomes the default environment for the duration of -the batch file, or until the next line which specifies -"\-envset". -.IP "\-[no]stick" -This flag only affects batch query runs. -It specifies that the \fIdig\fP environment (as read initially -or set by "\-envset" switch) is to be restored before each query -(line) in a \fIdig\fP batch file. -The default "\-nostick" means that the \fIdig\fP environment -does not stick, hence options specified on a single line -in a \fIdig\fP batch file will remain in effect for -subsequent lines (i.e. they are not restored to the -"sticky" default). - -.RE -.IP "+<query option>" -"+" is used to specify an option to be changed in the -query packet or to change \fIdig\fP output specifics. Many -of these are the same parameters accepted by -.IR nslookup (@SYS_OPS_EXT@). -If an option requires a parameter, the form is as -follows: -.sp 1 - +keyword[=value] -.sp 1 -Most keywords can be abbreviated. Parsing of the "+" -options is very simplistic \(em a value must not be -separated from its keyword by white space.

BIND's resolver has (as of BIND 4.9) been augmented to work -properly with \fIDig\fP. Essentially, \fIDig\fP is a straight-forward -(albeit not pretty) effort of parsing arguments and setting appropriate -parameters. \fIDig\fP uses resolver routines res_init(), res_mkquery(), -res_send() as well as accessing _res structure. -.SH FILES -.ta \w'/etc/resolv.confXX'u -/etc/resolv.conf initial domain name and name server -\./DiG.env default save file for default options -.br - addresses -.SH ENVIRONMENT -LOCALRES file to use in place of /etc/resolv.conf -.br -LOCALDEF default environment file -.SH AUTHOR -Steve Hotz -hotz@isi.edu -.SH ACKNOWLEDGMENTS -\fIDig\fP uses functions from -.IR nslookup (@SYS_OPS_EXT@) -authored by Andrew Cherenson. -.SH BUGS -\fIDig\fP has a serious case of "creeping featurism" -- the result of -considering several potential uses during it's development.

This is particularly annoying when running in -batch mode.

It gets this information -from a set of interconnected servers that are spread across the -country. By default, it simply converts between host names and -Internet addresses. However with the -t or -a options, it can be used -to find all of the information about this host that is maintained -by the domain server. -.PP -The arguments can be either host names or host numbers. The program -first attempts to interpret them as host numbers. If this fails, -it will treat them as host names. A host number consists of -first decimal numbers separated by dots, e.g. 128.6.4.194 -A host name -consists of names separated by dots, e.g. topaz.rutgers.edu. -Unless the name ends in a dot, the local domain -is automatically tacked on the end. Thus a Rutgers user can say -"host topaz", and it will actually look up "topaz.rutgers.edu". -If this fails, the name is tried unchanged (in this case, "topaz"). -This same convention is used for mail and other network utilities. -The actual suffix to tack on the end is obtained -by looking at the results of a "hostname" call, and using everything -starting at the first dot. (See below for a description of -how to customize the host name lookup.) -.PP -The first argument is the host name you want to look up. -If this is a number, an "inverse query" is done, i.e. the domain -system looks in a separate set of databases used to convert numbers -to names. -.PP -The second argument is optional. It -allows you to specify a particular server to query. If you don't -specify this argument, the default server (normally the local machine) -is used. -.PP -If a name is specified, you may see output of three different kinds. -Here is an example that shows all of them: -.br - % host sun4 -.br - sun4.rutgers.edu is a nickname for ATHOS.RUTGERS.EDU -.br - ATHOS.RUTGERS.EDU has address 128.6.5.46 -.br - ATHOS.RUTGERS.EDU has address 128.6.4.4 -.br - ATHOS.RUTGERS.EDU mail is handled by ARAMIS.RUTGERS.EDU -.br -The user has typed the command "host sun4". The first line indicates -that the name "sun4.rutgers.edu" is actually a nickname. The official -host name is "ATHOS.RUTGERS.EDU'. The next two lines show the -address. If a system has more than one network interface, there -will be a separate address for each. The last line indicates -that ATHOS.RUTGERS.EDU does not receive its own mail. Mail for -it is taken by ARAMIS.RUTGERS.EDU. There may be more than one -such line, since some systems have more than one other system -that will handle mail for them. Technically, every system that -can receive mail is supposed to have an entry of this kind. If -the system receives its own mail, there should be an entry -the mentions the system itself, for example -"XXX mail is handled by XXX". However many systems that receive -their own mail do not bother to mention that fact. If a system -has a "mail is handled by" entry, but no address, this indicates -that it is not really part of the Internet, but a system that is -on the network will forward mail to it. Systems on Usenet, Bitnet, -and a number of other networks have entries of this kind. -.PP -There are a number of options that can be used before the -host name. Most of these options are meaningful only to the -staff who have to maintain the domain database. -.PP -The option -w causes host to wait forever for a response. Normally -it will time out after around a minute. -.PP -The option -v causes printout to be in a "verbose" format. This -is the official domain master file format, which is documented -in the man page for "named". Without this option, output still follows -this format in general terms, but some attempt is made to make it -more intelligible to normal users. Without -v, -"a", "mx", and "cname" records -are written out as "has address", "mail is handled by", and -"is a nickname for", and TTL and class fields are not shown. -.PP -The option -r causes recursion to be turned off in the request. -This means that the name server will return only data it has in -its own database. It will not ask other servers for more -information. -.PP -The option -d turns on debugging. Network transactions are shown -in detail. -.PP -The option -t allows you to specify a particular type of information -to be looked up. The arguments are defined in the man page for -"named". Currently supported types are a, ns, md, mf, cname, -soa, mb, mg, mr, null, wks, ptr, hinfo, minfo, mx, uinfo, -uid, gid, unspec, and the wildcard, which may be written -as either "any" or "*". Types must be given in lower case. -Note that the default is to look first for "a", and then "mx", except -that if the verbose option is turned on, the default is only "a". -.PP -The option -a (for "all") is equivalent to "-v -t any". -.PP -The option -l causes a listing of a complete domain. E.g. -.br - host -l rutgers.edu -.br -will give a listing of all hosts in the rutgers.edu domain. The -t -option is used to filter what information is presented, as you -would expect. The default is address information, which also -include PTR and NS records. The command -.br - host -l -v -t any rutgers.edu -.br -will give a complete download of the zone data for rutgers.edu, -in the official master file format. (However the SOA record is -listed twice, for arcane reasons.) NOTE: -l is implemented by -doing a complete zone transfer and then filtering out the information -the you have asked for. This command should be used only if it -is absolutely necessary. -.SH CUSTOMIZING HOST NAME LOOKUP -In general, if the name supplied by the user does not -have any dots in it, a default domain is appended to the end. -This domain can be defined in /etc/resolv.conf, but is normally derived -by taking the local hostname after its first dot. The user can override -this, and specify a different default domain, using the environment -variable -.IR LOCALDOMAIN . -In addition, the user can supply his own abbreviations for host names. -They should be in a file consisting of one line per abbreviation. -Each line contains an abbreviation, a space, and then the full -host name. This file must be pointed to by an environment variable -.IR HOSTALIASES , -which is the name of the file. -.SH "See Also" -@INDOT@named (@SYS_OPS_EXT@) -.SH BUGS -Unexpected effects can happen when you type a name that is not -part of the local domain. Please always keep in mind the -fact that the local domain name is tacked onto the end of every -name, unless it ends in a dot. Only if this fails is the name -used unchanged. -.PP -The -l option only tries the first name server listed for the -domain that you have requested. If this server is dead, you -may need to specify a server manually. E.g. to get a listing -of foo.edu, you could try "host -t ns foo.edu" to get a list -of all the name servers for foo.edu, and then try "host -l foo.edu xxx" -for all xxx on the list of name servers, until you find one that -works. diff --git a/contrib/bind/man/hostname.7 b/contrib/bind/man/hostname.7 deleted file mode 100644 index 255c53cfe44d..000000000000 --- a/contrib/bind/man/hostname.7 +++ /dev/null @@ -1,108 +0,0 @@ -.\" Copyright (c) 1987 The Regents of the University of California. -.\" All rights reserved. -.\" -.\" Redistribution and use in source and binary forms are permitted -.\" provided that the above copyright notice and this paragraph are -.\" duplicated in all such forms and that any documentation, -.\" advertising materials, and other materials related to such -.\" distribution and use acknowledge that the software was developed -.\" by the University of California, Berkeley.

A domain is a hierarchical, dot-separated list -of subdomains. For example, the machine \fImonet\fP, in the \fIBerkeley\fP -subdomain of the \fIEDU\fP subdomain of the Internet Domain Name System -would be represented as -.br - \fImonet\fP.\fIBerkeley\fP.\fIEDU\fP -.br -(with no trailing dot). -.PP -Hostnames are often used with network client and server programs, -which must generally translate the name to an address for use. -(This task is usually performed by the library routine -.IR gethostbyname (@LIB_NETWORK_EXT@).) -The default method for resolving hostnames by the Internet name resolver is -to follow \s-1RFC\s+1 1535's security recommendations. Actions can be taken -by the administrator to override these recommendations and to have the -resolver behave the same as earlier, non-\s-1RFC\s+1 1535 resolvers. -.PP -The default method (using \s-1RFC\s+1 1535 guidelines) follows: -.PP -If the name consists of a single component, i.e. contains no dot, and if the -environment variable ``\s-1HOSTALIASES\s+1'' is set to the name of a file, -that file is searched for a string matching the input hostname. The file -should consist of lines made up of two strings separated by white-space, the -first of which is the hostname alias, and the second of which is the complete -hostname to be substituted for that alias. If a case-insensitive match is -found between the hostname to be resolved and the first field of a line in -the file, the substituted name is looked up with no further processing. -.PP -If there is at least one dot in the name, then the name is first tried as -is. The number of dots to cause this action is configurable by setting the -threshold using the ``\fIndots\fP'' option in -.I /etc/resolv.conf -(default: \fI1\fP). If the name ends with a dot, the trailing dot is -removed, and the remaining name is looked up (regardless of the setting of -the 'ndots' option) and no further processing is done. -.PP -If the input name does not end with a trailing dot, it is looked up by -searching through a list of domains until a match is found. If neither the -search option in the -.I /etc/resolv.conf -file or the ``\s-1LOCALDOMAIN\s+1'' environment variable is used, then the -search list of domains contains only the full domain specified by the domain -option (in -.IR /etc/resolv.conf ) -or the domain used in the local hostname (see -.IR hostname (@CMD_EXT@) -and -.IR resolver (@FORMAT_EXT@)). -For example, if the ``\fIdomain\fP'' option is set to \fICS.Berkeley.EDU\fP, -then only CS.Berkeley.EDU will be in the search list and will be the only -domain appended to the partial hostname, for example, ``\fIlithium\fP'', -making \fIlithium.CS.Berkeley.EDU\fP the only name to be tried using the -search list. -.PP -If the search option is used in -.I /etc/resolv.conf -or the environment variable, ``\s-1LOCALDOMAIN\s+1'' is set by the user, then -the search list will include what is set by these methods. For -example, if the ``\fIsearch\fP'' option contained -.br - \fICS.Berkeley.EDU CChem.Berkeley.EDU Berkeley.EDU\fP -.br -then the partial hostname (e.g., ``\fIlithium\fP'') will be tried with each -domainname appended (in the same order specified).

For -example, at Berkeley, ARPANET hosts may be referenced without adding -the ``berkeley.edu'' as long as their names do not conflict with a local -host name. -.SS Compatibility. -.PP -Certain old address formats are converted to the new format to provide -compatibility with the previous mail system. In particular, -.PP - user@host.ARPA -.PP -is allowed and -.PP - host:user -.PP -is converted to -.PP - user@host -.PP -to be consistent with the \fIrcp\fP(@CMD_EXT@) command. -.PP -Also, the syntax -.PP - host!user -.PP -is converted to: -.PP - user@host.UUCP -.PP -This is normally converted back to the ``host!user'' form before being sent -on for compatibility with older UUCP hosts. -.PP -The current implementation is not able to route messages automatically through -the UUCP network. Until that time you must explicitly tell the mail system -which hosts to send your message through to get to your final destination. -.SS Case Distinctions. -.PP -Domain names (i.e., anything after the ``@'' sign) may be given in any mixture -of upper and lower case with the exception of UUCP hostnames. Most hosts -accept any combination of case in user names, with the notable exception of -MULTICS sites. -.SS Route-addrs. -.PP -Under some circumstances it may be necessary to route a message through -several hosts to get it to the final destination. Normally this routing -is done automatically, but sometimes it is desirable to route the message -manually. Addresses which show these relays are termed ``route-addrs.'' -These use the syntax: -.PP - <@hosta,@hostb:user@hostc> -.PP -This specifies that the message should be sent to hosta, from there to hostb, -and finally to hostc. This path is forced even if there is a more efficient -path to hostc. -.PP -Route-addrs occur frequently on return addresses, since these are generally -augmented by the software at each host. It is generally possible to ignore -all but the ``user@domain'' part of the address to determine the actual -sender. -.SS Postmaster. -.PP -Every site is required to have a user or user alias designated ``postmaster'' -to which problems with the mail system may be addressed. -.SS Other Networks. -.PP -Some other networks can be reached by giving the name of the network as the -last component of the domain. \fIThis is not a standard feature\fP and may -not be supported at all sites. For example, messages to CSNET or BITNET sites -can often be sent to ``user@host.CSNET'' or ``user@host.BITNET'' respectively. -.SH BUGS -The RFC822 group syntax (``group:user1,user2,user3;'') is not supported -except in the special case of ``group:;'' because of a conflict with old -berknet-style addresses. -.PP -Route-Address syntax is grotty. -.PP -UUCP- and ARPANET-style addresses do not coexist politely. -.SH SEE ALSO -mail(@CMD_EXT@), sendmail(@SYS_OPS_EXT@); -Crocker, D.

This can be important for the correct processing -of \s-1$INCLUDE\s+1 files in primary zone files. -.LP -The ``cache'' line specifies that data in ``root.cache'' is to be placed in -the backup cache. Its main use is to specify data such as locations of root -domain servers. This cache is not used during normal operation, but is used -as ``hints'' to find the current root servers. The file ``root.cache'' is -in the same format as ``berkeley.edu.zone''. There can be more than one -``cache'' file specified. The ``root.cache'' file should be retrieved -periodically from \s-1FTP.RS.INTERNIC.NET\s+1 since it contains a list of -root servers, and this list changes periodically. -.LP -The first example ``primary'' line states that the file -``berkeley.edu.zone'' contains authoritative data for the ``Berkeley.EDU'' -zone. The file ``berkeley.edu.zone'' contains data in the master file -format described in RFC 883. All domain names are relative to the origin, in -this case, ``Berkeley.EDU'' (see below for a more detailed description). -The second ``primary'' line states that the file ``ucbhosts.rev'' contains -authoritative data for the domain ``32.128.IN-ADDR.ARPA,'' which is used to -translate addresses in network 128.32 to hostnames. Each master file should -begin with an SOA record for the zone (see below). -.LP -The first example ``secondary'' line specifies that all authoritative data -under ``CC.Berkeley.EDU'' is to be transferred from the name server at -128.32.137.8. If the transfer fails it will try 128.32.137.3 and continue -trying the addresses, up to 10, listed on this line. The secondary copy is -also authoritative for the specified domain. The first non-dotted-quad -address on this line will be taken as a filename in which to backup the -transferred zone. The name server will load the zone from this backup file -if it exists when it boots, providing a complete copy even if the master -servers are unreachable. Whenever a new copy of the domain is received by -automatic zone transfer from one of the master servers, this file will be -updated. If no file name is given, a temporary file will be used, and will -be deleted after each successful zone transfer. This is not recommended -since it is a needless waste of bandwidth. The second example ``secondary'' -line states that the address-to-hostname mapping for the subnet 128.32.136 -should be obtained from the same list of master servers as the previous zone. -.LP -The ``forwarders'' line specifies the addresses of sitewide servers that -will accept recursive queries from other servers. If the boot file -specifies one or more forwarders, then the server will send all queries for -data not in the cache to the forwarders first. Each forwarder will be asked -in turn until an answer is returned or the list is exhausted. If no answer -is forthcoming from a forwarder, the server will continue as it would have -without the forwarders line unless it is in ``forward-only'' mode. The -forwarding facility is useful to cause a large sitewide cache to be -generated on a master, and to reduce traffic over links to outside servers. -It can also be used to allow servers to run that do not have direct access -to the Internet, but wish to look up exterior names anyway. -.LP -The ``slave'' line (deprecated) is allowed for backward compatibility. Its -meaning is identical to ``options forward-only''. -.LP -The ``sortlist'' line can be used to indicate networks that are to be -preferred over other networks. Queries for host addresses from hosts on the -same network as the server will receive responses with local network -addresses listed first, then addresses on the sort list, then other -addresses. -.LP -The ``xfrnets'' directive (not shown) can be used to implement primitive -access control. If this directive is given, then your name server will -only answer zone transfer requests from hosts which are on networks listed -in your ``xfrnets'' directives. This directive may also be given as -``tcplist'' for compatibility with older, interim servers. -.LP -The ``include'' directive (not shown) can be used to process the contents -of some other file as though they appeared in place of the ``include'' -directive. This is useful if you have a lot of zones or if you have -logical groupings of zones which are maintained by different people. -The ``include'' directive takes one argument, that being the name of the -file whose contents are to be included. No quotes are necessary around -the file name. -.LP -The ``bogusns'' directive (not shown) tells \s-1BIND\s+1 that no queries -are to be sent to the specified name server addresses (which are specified -as dotted quads, not as domain names). This is useful when you know that -some popular server has bad data in a zone or cache, and you want to avoid -contamination while the problem is being fixed. -.LP -The ``limit'' directive can be used to change \s-1BIND\s+1's internal limits, -some of which (\fBdatasize\fP, for example) are implemented by the system and -others (like \fBtransfers-in\fP) by \s-1BIND\s+1 itself. The number following -the limit name can be scaled by postfixing a ``k,'' ``m,'' or ``g'' for -kilobytes, megabytes, and gigabytes respectively. -\fBdatasize\fP's argument sets the process data size enforced by the kernel. -\fINote:\fP not all systems provide a call to implement this -- on such -systems, the use of the \fBdatasize\fP parameter of ``limit'' will result in -a warning message. -\fBtransfers-in\fP's argument is the number of \fInamed-xfer\fP subprocesses -which \s-1BIND\s+1 will spawn at any one time. -\fBtransfers-per-ns\fP's argument is the maximum number of zone transfers to -be simultaneously initiated to any given remote name server. -\fBfiles\fP's argument sets the number of file descriptors available to -the process. \fINote:\fP not all systems provide a call to implement -this -- on such systems, the use of the \fBfiles\fP parameter of ``limit'' -will result in a warning message. -.LP -The ``options'' directive introduces a boolean specifier that changes the -behaviour of \s-1BIND\s+1. More than one option can be specified in a single -directive. The currently defined options are as follows: -\fBno-recursion\fP, which will cause \s-1BIND\s+1 to answer with a referral -rather than actual data whenever it receives a query for a name it is not -authoritative for -- don't set this on a server that is listed in any host's -\fIresolv.conf\fP file; -\fBno-fetch-glue\fP, which keeps \s-1BIND\s+1 from fetching missing glue when -constructing the ``additional data'' section of a response; this can be used -in conjunction with \fBno-recursion\fP to prevent \s-1BIND\s+1's cache from -ever growing in size or becoming corrupted; -\fBquery-log\fP, which causes all queries to be logged via -syslog(@SYS_OPS_EXT@) -- this is a lot of data, don't turn it on lightly; -\fBforward-only\fP, which causes the server to query only its forwarders -- -this option is normally used on machine that wishes to run a server but for -physical or administrative reasons cannot be given access to the Internet; -and \fBfake-iquery\fP, which tells \s-1BIND\s+1 to send back a useless and -bogus reply to ``inverse queries'' rather than responding with an error -- -this is helpful if you have a lot of microcomputers or SunOS hosts or both. -.LP -The ``check-names'' directive tells \s-1BIND\s+1 to check names in either -``primary'' or ``secondary'' zone files, or in messages (``response'') -received during recursion (for example, those which would be forwarded back -to a firewalled requestor). For each type of name, -\s-1BIND\s+1 can be told to ``fail'', such that a zone would not be loaded -or a response would not be cached or forwarded, or merely ``warn'' which -would cause a message to be emitted in the system operations logs, or to -``ignore'' the badness of a name and process it in the traditional fashion. -Names are considered good if they match RFC 952's expectations (if they are -host names), or if they consist only of printable \s-1ASCII\s+1 characters -(if they are not host names). -.LP -The ``max-fetch'' directive (not shown) is allowed for backward compatibility; -its meaning is identical to ``limit transfers-in''. -.PP -The master file consists of control information and a list of resource -records for objects in the zone of the forms: -.RS -.nf - -$INCLUDE <filename> <opt_domain> -$ORIGIN <domain> -<domain> <opt_ttl> <opt_class> <type> <resource_record_data> - -.fi -.RE -where -.I domain -is "." for root, "@" for the current origin, or a standard domain -name. If -.I domain -is a standard domain name that does not end with ``.'', the current origin -is appended to the domain. Domain names ending with ``.'' are -unmodified. -The -.I opt_domain -field is used to define an origin for the data in an included file. -It is equivalent to placing a $ORIGIN statement before the first -line of the included file. The field is optional. -Neither the -.I opt_domain -field nor $ORIGIN statements in the included file modify the current origin -for this file. -The -.I opt_ttl -field is an optional integer number for the time-to-live field. -It defaults to zero, meaning the minimum value specified in the SOA -record for the zone. -The -.I opt_class -field is the object address type; currently only one type is supported, -.BR IN , -for objects connected to the DARPA Internet. -The -.I type -field contains one of the following tokens; the data expected in the -.I resource_record_data -field is in parentheses. -.TP "\w'MINFO 'u" -A -a host address (dotted quad) -.IP NS -an authoritative name server (domain) -.IP MX -a mail exchanger (domain), preceded by a preference value (0..32767), -with lower numeric values representing higher logical preferences. -.IP CNAME -the canonical name for an alias (domain) -.IP SOA -marks the start of a zone of authority (domain of originating host, -domain address of maintainer, a serial number and the following -parameters in seconds: refresh, retry, expire and minimum TTL (see RFC 883)). -.IP NULL -a null resource record (no format or data) -.IP RP -a Responsible Person for some domain name (mailbox, TXT-referral) -.IP PTR -a domain name pointer (domain) -.IP HINFO -host information (cpu_type OS_type) -.PP -Resource records normally end at the end of a line, -but may be continued across lines between opening and closing parentheses. -Comments are introduced by semicolons and continue to the end of the line. -.PP -Note that there are other resource record types, not shown here. You should -consult the \s-1BIND\s+1 Operations Guide (``\s-1BOG\s+1'') for the complete -list. Some resource record types may have been standardized in newer RFC's -but not yet implemented in this version of \s-1BIND\s+1. -.PP -Each master zone file should begin with an SOA record for the zone. -An example SOA record is as follows: -.LP -.nf -@ IN SOA ucbvax.Berkeley.EDU. rwh.ucbvax.Berkeley.EDU. ( -.ta \w'x\ IN\ SOA\ 'u +\w'1989020501\ 'u - 1989020501 ; serial - 10800 ; refresh - 3600 ; retry - 3600000 ; expire - 86400 ) ; minimum -.fi -.LP -The SOA specifies a serial number, which should be changed each time the -master file is changed. Note that the serial number can be given as a -dotted number, but this is a \fIvery\fP unwise thing to do since the -translation to normal integers is via concatenation rather than -multiplication and addition. You can spell out the year, month, day of -month, and 0..99 version number and still fit inside the unsigned 32-bit -size of this field. It's true that we will have to rethink this strategy in -the year 4294 (Greg.) but we're not worried about it. Secondary servers -check the serial number at intervals specified by the refresh time in -seconds; if the serial number changes, a zone transfer will be done to load -the new data. If a master server cannot be contacted when a refresh is due, -the retry time specifies the interval at which refreshes should be attempted. -If a master server cannot be contacted within the interval given by the -expire time, all data from the zone is discarded by secondary servers. The -minimum value is the time-to-live (``\s-1TTL\s+1'') used by records in the -file with no explicit time-to-live value. -.SH NOTES -The boot file directives ``domain'' and ``suffixes'' have been -obsoleted by a more useful resolver-based implementation of -suffixing for partially qualified domain names. The prior mechanisms -could fail under a number of situations, especially when then local -nameserver did not have complete information. -.sp -The following signals have the specified effect when sent to the -server process using the -.IR kill (@CMD_EXT@) -command. -.IP SIGHUP -Causes server to read named.boot and reload the database.

Each node -of the tree contains the expected left & right subtree pointers, a short int -balance indicator, and a pointer to the user data. On a 32 bit system, this -means an overhead of 4+4+2+4 bytes per node (or, on a RISC or otherwise -alignment constrained system with implied padding, 4+4+4+4 bytes per node). -There is no key data type enforced by this package; a caller supplied -compare routine is used to compare user data blocks. -.PP -Balanced binary trees are very fast on searches and replacements, but have a -moderately high cost for additions and deletions. If your application does a -lot more searches and replacements than it does additions and deletions, the -balanced (AVL) binary tree is a good choice for a data structure. -.PP -.I Tree_init -creates an empty tree and binds it to -.I tree -(which for this and all other routines in this package should be declared as -a pointer to void or int, and passed by reference), which can then be used by -other routines in this package. Note that more than one -.I tree -variable can exist at once; thus multiple trees can be manipulated -simultaneously. -.PP -.I Tree_srch -searches a tree for a specific node and returns either -.I NULL -if no node was found, or the value of the user data pointer if the node -was found. -.I compare -is the address of a function to compare two user data blocks. This routine -should work much the way -.IR strcmp (3) -does; in fact, -.I strcmp -could be used if the user data was a \s-2NUL\s+2 terminated string. -.I data -is the address of a user data block to be used by -.I compare -as the search criteria. The tree is searched for a node where -.I compare -returns 0. -.PP -.I Tree_add -inserts or replaces a node in the specified tree. The tree specified by -.I tree -is searched as in -.I tree_srch, -and if a node is found to match -.I data, -then the -.I del_uar -function, if non\-\s-2NULL\s+2, is called with the address of the user data -block for the node (this routine should deallocate any dynamic memory which -is referenced exclusively by the node); the user data pointer for the node -is then replaced by the value of -.I data. -If no node is found to match, a new node is added (which may or may not -cause a transparent rebalance operation), with a user data pointer equal to -.I data. -A rebalance may or may not occur, depending on where the node is added -and what the rest of the tree looks like. -.I Tree_add -will return the -.I data -pointer unless catastrophe occurs in which case it will return \s-2NULL\s+2. -.PP -.I Tree_delete -deletes a node from -.I tree. -A rebalance may or may not occur, depending on where the node is removed from -and what the rest of the tree looks like. -.I Tree_delete -returns TRUE if a node was deleted, FALSE otherwise. -.PP -.I Tree_trav -traverses all of -.I tree, -calling -.I trav_uar -with the address of each user data block. If -.I trav_uar -returns FALSE at any time, -.I tree_trav -will immediately return FALSE to its caller. Otherwise all nodes will be -reached and -.I tree_trav -will return TRUE. -.PP -.I Tree_mung -deletes every node in -.I tree, -calling -.I del_uar -(if it is not \s-2NULL\s+2) with the user data address from each node (see -.I tree_add -and -.I tree_delete -above). The tree is left in the same state that -.I tree_init -leaves it in \- i.e., empty. -.SH BUGS -Should have a way for the caller to specify application specific -.I malloc -and -.I free -functions to be used internally when allocating meta data. -.SH AUTHOR -Paul Vixie, converted and augumented from Modula\-2 examples in -.I Algorithms & Data Structures, -Niklaus Wirth, Prentice\-Hall, ISBN 0\-13\-022005\-1. diff --git a/contrib/bind/res/Makefile b/contrib/bind/res/Makefile deleted file mode 100644 index 834d74a9c31d..000000000000 --- a/contrib/bind/res/Makefile +++ /dev/null @@ -1,114 +0,0 @@ -# -# from @(#)Makefile 5.16 (Berkeley) 3/14/88 -# $Id: Makefile,v 8.14 1997/06/01 20:34:37 vixie Exp $ -# - -## ++Copyright++ 1988, 1995 -## - -## Copyright (c) 1988, 1995 -## The Regents of the University of California.

dig now links against - * some of nslookup's .o files rather than #including them or maintaining - * local copies of them. in some sense, dig belongs in the nslookup - * subdirectory rather than up here in "tools", but that's for arc@sgi.com - * (owner of nslookup) to decide. - * - * while merging dig back into the BIND release, i made a number of - * structural changes. for one thing, i put all of dig's private - * library routines into this file rather than maintaining them in - * separate, #included, files. i don't like to #include ".c" files. - * i removed all calls to "bcopy", replacing them with structure - * assignments. i removed all "extern"'s of standard functions, - * replacing them with #include's of standard header files. this - * version of dig is probably as portable as the rest of BIND. - * - * i had to remove the query-time and packet-count statistics since - * the current libresolv.a is a lot harder to modify to maintain these - * than the 4.8 one (used in the original dig) was. for consolation, - * i added a "usage" message with extensive help text. - * - * to save my (limited, albeit) sanity, i ran "indent" over the source. - * i also added the standard berkeley/DEC copyrights, since this file now - * contains a fair amount of non-USC code. note that the berkeley and - * DEC copyrights do not prohibit redistribution, with or without fee; - * we add them only to protect ourselves (you have to claim copyright - * in order to disclaim liability and warranty). - * - * Paul Vixie, Palo Alto, CA, April 1993 - **************************************************************************** - - /******************************************************************* - ** DiG -- Domain Information Groper ** - ** ** - ** dig.c - Version 2.1 (7/12/94) ("BIND takeover") ** - ** ** - ** Developed by: Steve Hotz & Paul Mockapetris ** - ** USC Information Sciences Institute (USC-ISI) ** - ** Marina del Rey, California ** - ** 1989 ** - ** ** - ** dig.c - ** - ** Version 2.0 (9/1/90) ** - ** o renamed difftime() difftv() to avoid ** - ** clash with ANSI C ** - ** o fixed incorrect # args to strcmp,gettimeofday ** - ** o incorrect length specified to strncmp ** - ** o fixed broken -sticky -envsa -envset functions ** - ** o print options/flags redefined & modified ** - ** ** - ** Version 2.0.beta (5/9/90) ** - ** o output format - helpful to `doc` ** - ** o minor cleanup ** - ** o release to beta testers ** - ** ** - ** Version 1.1.beta (10/26/89) ** - ** o hanging zone transer (when REFUSED) fixed ** - ** o trailing dot added to domain names in RDATA ** - ** o ISI internal ** - ** ** - ** Version 1.0.tmp (8/27/89) ** - ** o Error in prnttime() fixed ** - ** o no longer dumps core on large pkts ** - ** o zone transfer (axfr) added ** - ** o -x added for inverse queries ** - ** (i.e. "dig -x 128.9.0.32") ** - ** o give address of default server ** - ** o accept broadcast to server @255.255.255.255 ** - ** ** - ** Version 1.0 (3/27/89) ** - ** o original release ** - ** ** - ** DiG is Public Domain, and may be used for any purpose as ** - ** long as this notice is not removed. ** - **** **** - **** NOTE: Version 2.0.beta is not for public distribution **** - **** **** - *******************************************************************/ - - -#define VERSION 22 -#define VSTRING "2.2" - -#include <sys/types.h> -#include <sys/param.h> -#include <sys/file.h> -#include <sys/stat.h> -#include <sys/socket.h> -#include <sys/time.h> - -#include <netinet/in.h> -#include <arpa/inet.h> -#include <arpa/nameser.h> - -#include <netdb.h> -#include <stdio.h> -#include <resolv.h> -#include <ctype.h> -#include <errno.h> -#include <string.h> -#include <setjmp.h> -#include <fcntl.h> - -#include "nslookup/res.h" -#include "../conf/portability.h" - -#define PRF_DEF 0x2ff9 -#define PRF_MIN 0xA930 -#define PRF_ZONE 0x24f9 - -#ifndef MAXHOSTNAMELEN -#define MAXHOSTNAMELEN 256 -#endif - -int eecode = 0;
