It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried. Most DNS administrators use -\fBdig\fR -to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. Other lookup tools tend to have less functionality than -\fBdig\fR. -.PP -Although -\fBdig\fR -is normally used with command\-line arguments, it also has a batch mode of operation for reading lookup requests from a file. A brief summary of its command\-line arguments and options is printed when the -\fB\-h\fR -option is given. Unlike earlier versions, the BIND9 implementation of -\fBdig\fR -allows multiple lookups to be issued from the command line. -.PP -Unless it is told to query a specific name server, -\fBdig\fR -will try each of the servers listed in -\fI/etc/resolv.conf\fR. -.PP -When no command line arguments or options are given, will perform an NS query for "." (the root). -.PP -It is possible to set per\-user defaults for -\fBdig\fR -via -\fI${HOME}/.digrc\fR. This file is read and any options in it are applied before the command line arguments. -.SH "SIMPLE USAGE" -.PP -A typical invocation of -\fBdig\fR -looks like: -.sp -.nf - dig @server name type -.fi -.sp -where: -.TP -\fBserver\fR -is the name or IP address of the name server to query. This can be an IPv4 address in dotted\-decimal notation or an IPv6 address in colon\-delimited notation. When the supplied -\fIserver\fR -argument is a hostname, -\fBdig\fR -resolves that name before querying that name server. If no -\fIserver\fR -argument is provided, -\fBdig\fR -consults -\fI/etc/resolv.conf\fR -and queries the name servers listed there. The reply from the name server that responds is displayed. -.TP -\fBname\fR -is the name of the resource record that is to be looked up. -.TP -\fBtype\fR -indicates what type of query is required \(em ANY, A, MX, SIG, etc. -\fItype\fR -can be any valid query type. If no -\fItype\fR -argument is supplied, -\fBdig\fR -will perform a lookup for an A record. -.SH "OPTIONS" -.PP -The -\fB\-b\fR -option sets the source IP address of the query to -\fIaddress\fR. This must be a valid address on one of the host's network interfaces or "0.0.0.0" or "::". An optional port may be specified by appending "#<port>" -.PP -The default query class (IN for internet) is overridden by the -\fB\-c\fR -option. -\fIclass\fR -is any valid class, such as HS for Hesiod records or CH for CHAOSNET records. -.PP -The -\fB\-f\fR -option makes -\fBdig \fR -operate in batch mode by reading a list of lookup requests to process from the file -\fIfilename\fR. The file contains a number of queries, one per line. Each entry in the file should be organised in the same way they would be presented as queries to -\fBdig\fR -using the command\-line interface. -.PP -If a non\-standard port number is to be queried, the -\fB\-p\fR -option is used. -\fIport#\fR -is the port number that -\fBdig\fR -will send its queries instead of the standard DNS port number 53. This option would be used to test a name server that has been configured to listen for queries on a non\-standard port number. -.PP -The -\fB\-4\fR -option forces -\fBdig\fR -to only use IPv4 query transport. The -\fB\-6\fR -option forces -\fBdig\fR -to only use IPv6 query transport. -.PP -The -\fB\-t\fR -option sets the query type to -\fItype\fR. It can be any valid query type which is supported in BIND9. The default query type "A", unless the -\fB\-x\fR -option is supplied to indicate a reverse lookup. A zone transfer can be requested by specifying a type of AXFR. When an incremental zone transfer (IXFR) is required, -\fItype\fR -is set to -ixfr=N. The incremental zone transfer will contain the changes made to the zone since the serial number in the zone's SOA record was -\fIN\fR. -.PP -Reverse lookups \- mapping addresses to names \- are simplified by the -\fB\-x\fR -option. -\fIaddr\fR -is an IPv4 address in dotted\-decimal notation, or a colon\-delimited IPv6 address. When this option is used, there is no need to provide the -\fIname\fR, -\fIclass\fR -and -\fItype\fR -arguments. -\fBdig\fR -automatically performs a lookup for a name like -11.12.13.10.in\-addr.arpa -and sets the query type and class to PTR and IN respectively. By default, IPv6 addresses are looked up using nibble format under the IP6.ARPA domain. To use the older RFC1886 method using the IP6.INT domain specify the -\fB\-i\fR -option. Bit string labels (RFC2874) are now experimental and are not attempted. -.PP -To sign the DNS queries sent by -\fBdig\fR -and their responses using transaction signatures (TSIG), specify a TSIG key file using the -\fB\-k\fR -option. You can also specify the TSIG key itself on the command line using the -\fB\-y\fR -option; -\fIname\fR -is the name of the TSIG key and -\fIkey\fR -is the actual key. The key is a base\-64 encoded string, typically generated by -\fBdnssec\-keygen\fR(8). Caution should be taken when using the -\fB\-y\fR -option on multi\-user systems as the key can be visible in the output from -\fBps\fR(1 ) -or in the shell's history file. When using TSIG authentication with -\fBdig\fR, the name server that is queried needs to know the key and algorithm that is being used. In BIND, this is done by providing appropriate -\fBkey\fR -and -\fBserver\fR -statements in -\fInamed.conf\fR. -.SH "QUERY OPTIONS" -.PP -\fBdig\fR -provides a number of query options which affect the way in which lookups are made and the results displayed. Some of these set or reset flag bits in the query header, some determine which sections of the answer get printed, and others determine the timeout and retry strategies. -.PP -Each query option is identified by a keyword preceded by a plus sign (+). Some keywords set or reset an option. These may be preceded by the string -no -to negate the meaning of that keyword. Other keywords assign values to options like the timeout interval. They have the form -\fB+keyword=value\fR. The query options are: -.TP -\fB+[no]tcp\fR -Use [do not use] TCP when querying name servers. The default behaviour is to use UDP unless an AXFR or IXFR query is requested, in which case a TCP connection is used. -.TP -\fB+[no]vc\fR -Use [do not use] TCP when querying name servers. This alternate syntax to -\fI+[no]tcp\fR -is provided for backwards compatibility. The "vc" stands for "virtual circuit". -.TP -\fB+[no]ignore\fR -Ignore truncation in UDP responses instead of retrying with TCP. By default, TCP retries are performed. -.TP -\fB+domain=somename\fR -Set the search list to contain the single domain -\fIsomename\fR, as if specified in a -\fBdomain\fR -directive in -\fI/etc/resolv.conf\fR, and enable search list processing as if the -\fI+search\fR -option were given. -.TP -\fB+[no]search\fR -Use [do not use] the search list defined by the searchlist or domain directive in -\fIresolv.conf\fR -(if any). The search list is not used by default. -.TP -\fB+[no]defname\fR -Deprecated, treated as a synonym for -\fI+[no]search\fR -.TP -\fB+[no]aaonly\fR -Sets the "aa" flag in the query. -.TP -\fB+[no]aaflag\fR -A synonym for -\fI+[no]aaonly\fR. -.TP -\fB+[no]adflag\fR -Set [do not set] the AD (authentic data) bit in the query. The AD bit currently has a standard meaning only in responses, not in queries, but the ability to set the bit in the query is provided for completeness. -.TP -\fB+[no]cdflag\fR -Set [do not set] the CD (checking disabled) bit in the query. This requests the server to not perform DNSSEC validation of responses. -.TP -\fB+[no]cl\fR -Display [do not display] the CLASS when printing the record. -.TP -\fB+[no]ttlid\fR -Display [do not display] the TTL when printing the record. -.TP -\fB+[no]recurse\fR -Toggle the setting of the RD (recursion desired) bit in the query. This bit is set by default, which means -\fBdig\fR -normally sends recursive queries. Recursion is automatically disabled when the -\fI+nssearch\fR -or -\fI+trace\fR -query options are used. -.TP -\fB+[no]nssearch\fR -When this option is set, -\fBdig\fR -attempts to find the authoritative name servers for the zone containing the name being looked up and display the SOA record that each name server has for the zone. -.TP -\fB+[no]trace\fR -Toggle tracing of the delegation path from the root name servers for the name being looked up. Tracing is disabled by default. When tracing is enabled, -\fBdig\fR -makes iterative queries to resolve the name being looked up. It will follow referrals from the root servers, showing the answer from each server that was used to resolve the lookup. -.TP -\fB+[no]cmd\fR -toggles the printing of the initial comment in the output identifying the version of -\fBdig\fR -and the query options that have been applied. This comment is printed by default. -.TP -\fB+[no]short\fR -Provide a terse answer. The default is to print the answer in a verbose form. -.TP -\fB+[no]identify\fR -Show [or do not show] the IP address and port number that supplied the answer when the -\fI+short\fR -option is enabled. If short form answers are requested, the default is not to show the source address and port number of the server that provided the answer. -.TP -\fB+[no]comments\fR -Toggle the display of comment lines in the output. The default is to print comments. -.TP -\fB+[no]stats\fR -This query option toggles the printing of statistics: when the query was made, the size of the reply and so on. The default behaviour is to print the query statistics. -.TP -\fB+[no]qr\fR -Print [do not print] the query as it is sent. By default, the query is not printed. -.TP -\fB+[no]question\fR -Print [do not print] the question section of a query when an answer is returned. The default is to print the question section as a comment. -.TP -\fB+[no]answer\fR -Display [do not display] the answer section of a reply. The default is to display it. -.TP -\fB+[no]authority\fR -Display [do not display] the authority section of a reply. The default is to display it. -.TP -\fB+[no]additional\fR -Display [do not display] the additional section of a reply. The default is to display it. -.TP -\fB+[no]all\fR -Set or clear all display flags. -.TP -\fB+time=T\fR -Sets the timeout for a query to -\fIT\fR -seconds. The default time out is 5 seconds. An attempt to set -\fIT\fR -to less than 1 will result in a query timeout of 1 second being applied. -.TP -\fB+tries=T\fR -Sets the number of times to try UDP queries to server to -\fIT\fR -instead of the default, 3. If -\fIT\fR -is less than or equal to zero, the number of tries is silently rounded up to 1. -.TP -\fB+retry=T\fR -Sets the number of times to retry UDP queries to server to -\fIT\fR -instead of the default, 2. Unlike -\fI+tries\fR, this does not include the initial query. -.TP -\fB+ndots=D\fR -Set the number of dots that have to appear in -\fIname\fR -to -\fID\fR -for it to be considered absolute. The default value is that defined using the ndots statement in -\fI/etc/resolv.conf\fR, or 1 if no ndots statement is present. Names with fewer dots are interpreted as relative names and will be searched for in the domains listed in the -\fBsearch\fR -or -\fBdomain\fR -directive in -\fI/etc/resolv.conf\fR. -.TP -\fB+bufsize=B\fR -Set the UDP message buffer size advertised using EDNS0 to -\fIB\fR -bytes. The maximum and minimum sizes of this buffer are 65535 and 0 respectively. Values outside this range are rounded up or down appropriately. -.TP -\fB+[no]multiline\fR -Print records like the SOA records in a verbose multi\-line format with human\-readable comments. The default is to print each record on a single line, to facilitate machine parsing of the -\fBdig\fR -output. -.TP -\fB+[no]fail\fR -Do not try the next server if you receive a SERVFAIL. The default is to not try the next server which is the reverse of normal stub resolver behaviour. -.TP -\fB+[no]besteffort\fR -Attempt to display the contents of messages which are malformed. The default is to not display malformed answers. -.TP -\fB+[no]dnssec\fR -Requests DNSSEC records be sent by setting the DNSSEC OK bit (DO) in the OPT record in the additional section of the query. -.TP -\fB+[no]sigchase\fR -Chase DNSSEC signature chains. Requires dig be compiled with \-DDIG_SIGCHASE. -.TP -\fB+trusted\-key=####\fR -Specifies a file containing trusted keys to be used with -\fB+sigchase\fR. Each DNSKEY record must be on its own line. -.sp -If not specified -\fBdig\fR -will look for -\fI/etc/trusted\-key.key\fR -then -\fItrusted\-key.key\fR -in the current directory. -.sp -Requires dig be compiled with \-DDIG_SIGCHASE. -.TP -\fB+[no]topdown\fR -When chasing DNSSEC signature chains perform a top down validation. Requires dig be compiled with \-DDIG_SIGCHASE. -.SH "MULTIPLE QUERIES" -.PP -The BIND 9 implementation of -\fBdig \fR -supports specifying multiple queries on the command line (in addition to supporting the -\fB\-f\fR -batch file option). Each of those queries can be supplied with its own set of flags, options and query options. -.PP -In this case, each -\fIquery\fR -argument represent an individual query in the command\-line syntax described above. Each consists of any of the standard options and flags, the name to be looked up, an optional query type and class and any query options that should be applied to that query. -.PP -A global set of query options, which should be applied to all queries, can also be supplied. These global query options must precede the first tuple of name, class, type, options, flags, and query options supplied on the command line. Any global query options (except the -\fB+[no]cmd\fR -option) can be overridden by a query\-specific set of query options.

A global query option of -\fI+qr\fR -is applied, so that -\fBdig\fR -shows the initial query it made for each lookup. The final query has a local query option of -\fI+noqr\fR -which means that -\fBdig\fR -will not print the initial query when it looks up the NS records for -isc.org. -.SH "FILES" -.PP -\fI/etc/resolv.conf\fR -.PP -\fI${HOME}/.digrc\fR -.SH "SEE ALSO" -.PP -\fBhost\fR(1), -\fBnamed\fR(8), -\fBdnssec\-keygen\fR(8), -RFC1035. -.SH "BUGS " -.PP -There are probably too many query options. diff --git a/contrib/bind9/bin/dig/dig.c b/contrib/bind9/bin/dig/dig.c deleted file mode 100644 index 52df6608685b..000000000000 --- a/contrib/bind9/bin/dig/dig.c +++ /dev/null @@ -1,1670 +0,0 @@ -/* - * Copyright (C) 2004, 2005 Internet Systems Consortium, Inc.

It performs DNS lookups and -displays the answers that are returned from the name server(s) that -were queried. Most DNS administrators use <command>dig</command> to -troubleshoot DNS problems because of its flexibility, ease of use and -clarity of output. Other lookup tools tend to have less functionality -than <command>dig</command>. -</para> - -<para> -Although <command>dig</command> is normally used with command-line -arguments, it also has a batch mode of operation for reading lookup -requests from a file. A brief summary of its command-line arguments -and options is printed when the <option>-h</option> option is given. -Unlike earlier versions, the BIND9 implementation of -<command>dig</command> allows multiple lookups to be issued from the -command line. -</para> - -<para> -Unless it is told to query a specific name server, -<command>dig</command> will try each of the servers listed in -<filename>/etc/resolv.conf</filename>. -</para> - -<para> -When no command line arguments or options are given, will perform an -NS query for "."

This file is read and any options in it -are applied before the command line arguments. -</para> - -</refsect1> - -<refsect1> -<title>SIMPLE USAGE</title> - -<para> -A typical invocation of <command>dig</command> looks like: -<programlisting> dig @server name type </programlisting> where: - -<variablelist> - -<varlistentry><term><constant>server</constant></term> -<listitem><para> -is the name or IP address of the name server to query. This can be an IPv4 -address in dotted-decimal notation or an IPv6 -address in colon-delimited notation. When the supplied -<parameter>server</parameter> argument is a hostname, -<command>dig</command> resolves that name before querying that name -server. If no <parameter>server</parameter> argument is provided, -<command>dig</command> consults <filename>/etc/resolv.conf</filename> -and queries the name servers listed there. The reply from the name -server that responds is displayed. -</para></listitem></varlistentry> - -<varlistentry><term><constant>name</constant></term> -<listitem><para> -is the name of the resource record that is to be looked up. -</para></listitem></varlistentry> - -<varlistentry><term><constant>type</constant></term> -<listitem><para> -indicates what type of query is required — -ANY, A, MX, SIG, etc. -<parameter>type</parameter> can be any valid query type. If no -<parameter>type</parameter> argument is supplied, -<command>dig</command> will perform a lookup for an A record. -</para></listitem></varlistentry> - -</variablelist> -</para> - -</refsect1> - -<refsect1> -<title>OPTIONS</title> - -<para> -The <option>-b</option> option sets the source IP address of the query -to <parameter>address</parameter>. This must be a valid address on -one of the host's network interfaces or "0.0.0.0" or "::". An optional port -may be specified by appending "#<port>" -</para> - -<para> -The default query class (IN for internet) is overridden by the -<option>-c</option> option. <parameter>class</parameter> is any valid -class, such as HS for Hesiod records or CH for CHAOSNET records. -</para> - -<para> -The <option>-f</option> option makes <command>dig </command> operate -in batch mode by reading a list of lookup requests to process from the -file <parameter>filename</parameter>. The file contains a number of -queries, one per line. Each entry in the file should be organised in -the same way they would be presented as queries to -<command>dig</command> using the command-line interface. -</para> - -<para> -If a non-standard port number is to be queried, the -<option>-p</option> option is used. <parameter>port#</parameter> is -the port number that <command>dig</command> will send its queries -instead of the standard DNS port number 53. This option would be used -to test a name server that has been configured to listen for queries -on a non-standard port number. -</para> - -<para> -The <option>-4</option> option forces <command>dig</command> to only -use IPv4 query transport. The <option>-6</option> option forces -<command>dig</command> to only use IPv6 query transport. -</para> - -<para> -The <option>-t</option> option sets the query type to -<parameter>type</parameter>. It can be any valid query type which is -supported in BIND9. The default query type "A", unless the -<option>-x</option> option is supplied to indicate a reverse lookup. -A zone transfer can be requested by specifying a type of AXFR. When -an incremental zone transfer (IXFR) is required, -<parameter>type</parameter> is set to <literal>ixfr=N</literal>. -The incremental zone transfer will contain the changes made to the zone -since the serial number in the zone's SOA record was -<parameter>N</parameter>. -</para> - -<para> -Reverse lookups - mapping addresses to names - are simplified by the -<option>-x</option> option. <parameter>addr</parameter> is an IPv4 -address in dotted-decimal notation, or a colon-delimited IPv6 address. -When this option is used, there is no need to provide the -<parameter>name</parameter>, <parameter>class</parameter> and -<parameter>type</parameter> arguments. <command>dig</command> -automatically performs a lookup for a name like -<literal>11.12.13.10.in-addr.arpa</literal> and sets the query type and -class to PTR and IN respectively. By default, IPv6 addresses are -looked up using nibble format under the IP6.ARPA domain. -To use the older RFC1886 method using the IP6.INT domain -specify the <option>-i</option> option. Bit string labels (RFC2874) -are now experimental and are not attempted. -</para> - -<para> -To sign the DNS queries sent by <command>dig</command> and their -responses using transaction signatures (TSIG), specify a TSIG key file -using the <option>-k</option> option. You can also specify the TSIG -key itself on the command line using the <option>-y</option> option; -<parameter>name</parameter> is the name of the TSIG key and -<parameter>key</parameter> is the actual key. The key is a base-64 -encoded string, typically generated by <citerefentry> -<refentrytitle>dnssec-keygen</refentrytitle><manvolnum>8</manvolnum> -</citerefentry>. - -Caution should be taken when using the <option>-y</option> option on -multi-user systems as the key can be visible in the output from -<citerefentry> <refentrytitle>ps</refentrytitle><manvolnum>1 -</manvolnum> </citerefentry> or in the shell's history file. When -using TSIG authentication with <command>dig</command>, the name -server that is queried needs to know the key and algorithm that is -being used. In BIND, this is done by providing appropriate -<command>key</command> and <command>server</command> statements in -<filename>named.conf</filename>. -</para> - -</refsect1> - -<refsect1> -<title>QUERY OPTIONS</title> - -<para> -<command>dig</command> provides a number of query options which affect -the way in which lookups are made and the results displayed. Some of -these set or reset flag bits in the query header, some determine which -sections of the answer get printed, and others determine the timeout -and retry strategies. -</para> - -<para> -Each query option is identified by a keyword preceded by a plus sign -(<literal>+</literal>). Some keywords set or reset an option. These may be preceded -by the string <literal>no</literal> to negate the meaning of that keyword.

This must be a valid address on -one of the host's network interfaces or "0.0.0.0" or "::". An optional port -may be specified by appending "#<port>" -</p> -<p> -The default query class (IN for internet) is overridden by the -<code class="option">-c</code> option. <em class="parameter"><code>class</code></em> is any valid -class, such as HS for Hesiod records or CH for CHAOSNET records. -</p> -<p> -The <code class="option">-f</code> option makes <span><strong class="command">dig </strong></span> operate -in batch mode by reading a list of lookup requests to process from the -file <em class="parameter"><code>filename</code></em>. The file contains a number of -queries, one per line.

It can be any valid query type which is -supported in BIND9. The default query type "A", unless the -<code class="option">-x</code> option is supplied to indicate a reverse lookup. -A zone transfer can be requested by specifying a type of AXFR. When -an incremental zone transfer (IXFR) is required, -<em class="parameter"><code>type</code></em> is set to <code class="literal">ixfr=N</code>. -The incremental zone transfer will contain the changes made to the zone -since the serial number in the zone's SOA record was -<em class="parameter"><code>N</code></em>. -</p> -<p> -Reverse lookups - mapping addresses to names - are simplified by the -<code class="option">-x</code> option. <em class="parameter"><code>addr</code></em> is an IPv4 -address in dotted-decimal notation, or a colon-delimited IPv6 address. -When this option is used, there is no need to provide the -<em class="parameter"><code>name</code></em>, <em class="parameter"><code>class</code></em> and -<em class="parameter"><code>type</code></em> arguments. <span><strong class="command">dig</strong></span> -automatically performs a lookup for a name like -<code class="literal">11.12.13.10.in-addr.arpa</code> and sets the query type and -class to PTR and IN respectively. By default, IPv6 addresses are -looked up using nibble format under the IP6.ARPA domain. -To use the older RFC1886 method using the IP6.INT domain -specify the <code class="option">-i</code> option.

You can also specify the TSIG -key itself on the command line using the <code class="option">-y</code> option; -<em class="parameter"><code>name</code></em> is the name of the TSIG key and -<em class="parameter"><code>key</code></em> is the actual key. The key is a base-64 -encoded string, typically generated by <span class="citerefentry"><span class="refentrytitle">dnssec-keygen</span>(8)</span>. - -Caution should be taken when using the <code class="option">-y</code> option on -multi-user systems as the key can be visible in the output from -<span class="citerefentry"><span class="refentrytitle">ps</span>(1 -)</span> or in the shell's history file. When -using TSIG authentication with <span><strong class="command">dig</strong></span>, the name -server that is queried needs to know the key and algorithm that is -being used.

It is normally used to convert names to IP addresses and vice versa. When no arguments or options are given, -\fBhost\fR -prints a short summary of its command line arguments and options. -.PP -\fIname\fR -is the domain name that is to be looked up. It can also be a dotted\-decimal IPv4 address or a colon\-delimited IPv6 address, in which case -\fBhost\fR -will by default perform a reverse lookup for that address. -\fIserver\fR -is an optional argument which is either the name or IP address of the name server that -\fBhost\fR -should query instead of the server or servers listed in -\fI/etc/resolv.conf\fR. -.PP -The -\fB\-a\fR -(all) option is equivalent to setting the -\fB\-v\fR -option and asking -\fBhost\fR -to make a query of type ANY. -.PP -When the -\fB\-C\fR -option is used, -\fBhost\fR -will attempt to display the SOA records for zone -\fIname\fR -from all the listed authoritative name servers for that zone. The list of name servers is defined by the NS records that are found for the zone. -.PP -The -\fB\-c\fR -option instructs to make a DNS query of class -\fIclass\fR. This can be used to lookup Hesiod or Chaosnet class resource records. The default class is IN (Internet). -.PP -Verbose output is generated by -\fBhost\fR -when the -\fB\-d\fR -or -\fB\-v\fR -option is used. The two options are equivalent. They have been provided for backwards compatibility. In previous versions, the -\fB\-d\fR -option switched on debugging traces and -\fB\-v\fR -enabled verbose output. -.PP -List mode is selected by the -\fB\-l\fR -option. This makes -\fBhost\fR -perform a zone transfer for zone -\fIname\fR. Transfer the zone printing out the NS, PTR and address records (A/AAAA). If combined with -\fB\-a\fR -all records will be printed. -.PP -The -\fB\-i\fR -option specifies that reverse lookups of IPv6 addresses should use the IP6.INT domain as defined in RFC1886. The default is to use IP6.ARPA. -.PP -The -\fB\-N\fR -option sets the number of dots that have to be in -\fIname\fR -for it to be considered absolute. The default value is that defined using the ndots statement in -\fI/etc/resolv.conf\fR, or 1 if no ndots statement is present. Names with fewer dots are interpreted as relative names and will be searched for in the domains listed in the -\fBsearch\fR -or -\fBdomain\fR -directive in -\fI/etc/resolv.conf\fR. -.PP -The number of UDP retries for a lookup can be changed with the -\fB\-R\fR -option. -\fInumber\fR -indicates how many times -\fBhost\fR -will repeat a query that does not get answered. The default number of retries is 1. If -\fInumber\fR -is negative or zero, the number of retries will default to 1. -.PP -Non\-recursive queries can be made via the -\fB\-r\fR -option. Setting this option clears the -\fBRD\fR -\(em recursion desired \(em bit in the query which -\fBhost\fR -makes. This should mean that the name server receiving the query will not attempt to resolve -\fIname\fR. The -\fB\-r\fR -option enables -\fBhost\fR -to mimic the behaviour of a name server by making non\-recursive queries and expecting to receive answers to those queries that are usually referrals to other name servers. -.PP -By default -\fBhost\fR -uses UDP when making queries. The -\fB\-T\fR -option makes it use a TCP connection when querying the name server. TCP will be automatically selected for queries that require it, such as zone transfer (AXFR) requests. -.PP -The -\fB\-4\fR -option forces -\fBhost\fR -to only use IPv4 query transport. The -\fB\-6\fR -option forces -\fBhost\fR -to only use IPv6 query transport. -.PP -The -\fB\-t\fR -option is used to select the query type. -\fItype\fR -can be any recognised query type: CNAME, NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified, -\fBhost\fR -automatically selects an appropriate query type. By default it looks for A records, but if the -\fB\-C\fR -option was given, queries will be made for SOA records, and if -\fIname\fR -is a dotted\-decimal IPv4 address or colon\-delimited IPv6 address, -\fBhost\fR -will query for PTR records. If a query type of IXFR is chosen the starting serial number can be specified by appending an equal followed by the starting serial number (e.g. \-t IXFR=12345678). -.PP -The time to wait for a reply can be controlled through the -\fB\-W\fR -and -\fB\-w\fR -options. The -\fB\-W\fR -option makes -\fBhost\fR -wait for -\fIwait\fR -seconds. If -\fIwait\fR -is less than one, the wait interval is set to one second. When the -\fB\-w\fR -option is used, -\fBhost\fR -will effectively wait forever for a reply. The time to wait for a response will be set to the number of seconds given by the hardware's maximum value for an integer quantity. -.SH "FILES" -.PP -\fI/etc/resolv.conf\fR -.SH "SEE ALSO" -.PP -\fBdig\fR(1), -\fBnamed\fR(8). diff --git a/contrib/bind9/bin/dig/host.c b/contrib/bind9/bin/dig/host.c deleted file mode 100644 index 468d53bf944e..000000000000 --- a/contrib/bind9/bin/dig/host.c +++ /dev/null @@ -1,740 +0,0 @@ -/* - * Copyright (C) 2004, 2005 Internet Systems Consortium, Inc.

Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain. Non\-interactive mode is used to print just the name and requested information for a host or domain. -.SH "ARGUMENTS" -.PP -Interactive mode is entered in the following cases: -.TP 3 -1. -when no arguments are given (the default name server will be used) -.TP -2. -when the first argument is a hyphen (\-) and the second argument is the host name or Internet address of a name server. -.PP -Non\-interactive mode is used when the name or Internet address of the host to be looked up is given as the first argument. The optional second argument specifies the host name or address of a name server. -.PP -Options can also be specified on the command line if they precede the arguments and are prefixed with a hyphen. For example, to change the default query type to host information, and the initial timeout to 10 seconds, type: -.IP .sp .nf nslookup \-query=hinfo \-timeout=10 .fi -.SH "INTERACTIVE COMMANDS" -.TP -host [server] -Look up information for host using the current default server or using server, if specified.

It can also generate keys for use with TSIG (Transaction Signatures), as defined in RFC 2845. -.SH "OPTIONS" -.TP -\-a \fIalgorithm\fR -Selects the cryptographic algorithm. The value of -\fBalgorithm\fR -must be one of RSAMD5 (RSA) or RSASHA1, DSA, DH (Diffie Hellman), or HMAC\-MD5. These values are case insensitive. -.sp -Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended. For TSIG, HMAC\-MD5 is mandatory. -.sp -Note 2: HMAC\-MD5 and DH automatically set the \-k flag. -.TP -\-b \fIkeysize\fR -Specifies the number of bits in the key. The choice of key size depends on the algorithm used. RSAMD5 / RSASHA1 keys must be between 512 and 2048 bits. Diffie Hellman keys must be between 128 and 4096 bits. DSA keys must be between 512 and 1024 bits and an exact multiple of 64. HMAC\-MD5 keys must be between 1 and 512 bits. -.TP -\-n \fInametype\fR -Specifies the owner type of the key. The value of -\fBnametype\fR -must either be ZONE (for a DNSSEC zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with a host (KEY)), USER (for a key associated with a user(KEY)) or OTHER (DNSKEY). These values are case insensitive. -.TP -\-c \fIclass\fR -Indicates that the DNS record containing the key should have the specified class. If not specified, class IN is used. -.TP -\-e -If generating an RSAMD5/RSASHA1 key, use a large exponent. -.TP -\-f \fIflag\fR -Set the specified flag in the flag field of the KEY/DNSKEY record. The only recognized flag is KSK (Key Signing Key) DNSKEY. -.TP -\-g \fIgenerator\fR -If generating a Diffie Hellman key, use this generator. Allowed values are 2 and 5. If no generator is specified, a known prime from RFC 2539 will be used if possible; otherwise the default is 2. -.TP -\-h -Prints a short summary of the options and arguments to -\fBdnssec\-keygen\fR. -.TP -\-k -Generate KEY records rather than DNSKEY records. -.TP -\-p \fIprotocol\fR -Sets the protocol value for the generated key. The protocol is a number between 0 and 255. The default is 3 (DNSSEC). Other possible values for this argument are listed in RFC 2535 and its successors. -.TP -\-r \fIrandomdev\fR -Specifies the source of randomness. If the operating system does not provide a -\fI/dev/random\fR -or equivalent device, the default source of randomness is keyboard input. -\fIrandomdev\fR -specifies the name of a character device or file containing random data to be used instead of the default. The special value -\fIkeyboard\fR -indicates that keyboard input should be used. -.TP -\-s \fIstrength\fR -Specifies the strength value of the key. The strength is a number between 0 and 15, and currently has no defined purpose in DNSSEC. -.TP -\-t \fItype\fR -Indicates the use of the key. -\fBtype\fR -must be one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default is AUTHCONF. AUTH refers to the ability to authenticate data, and CONF the ability to encrypt data. -.TP -\-v \fIlevel\fR -Sets the debugging level. -.SH "GENERATED KEYS" -.PP -When -\fBdnssec\-keygen\fR -completes successfully, it prints a string of the form -\fIKnnnn.+aaa+iiiii\fR -to the standard output. This is an identification string for the key it has generated. -.TP 3 -\(bu -\fInnnn\fR -is the key name. -.TP -\(bu -\fIaaa\fR -is the numeric representation of the algorithm. -.TP -\(bu -\fIiiiii\fR -is the key identifier (or footprint). -.PP -\fBdnssec\-keygen\fR -creates two file, with names based on the printed string. -\fIKnnnn.+aaa+iiiii.key\fR -contains the public key, and -\fIKnnnn.+aaa+iiiii.private\fR -contains the private key. -.PP -The -\fI.key\fR -file contains a DNS KEY record that can be inserted into a zone file (directly or with a $INCLUDE statement). -.PP -The -\fI.private\fR -file contains algorithm specific fields.

It generates NSEC and RRSIG records and produces a signed version of the zone. The security status of delegations from the signed zone (that is, whether the child zones are secure or not) is determined by the presence or absence of a -\fIkeyset\fR -file for each child zone. -.SH "OPTIONS" -.TP -\-a -Verify all generated signatures. -.TP -\-c \fIclass\fR -Specifies the DNS class of the zone. -.TP -\-k \fIkey\fR -Treat specified key as a key signing key ignoring any key flags. This option may be specified multiple times. -.TP -\-l \fIdomain\fR -Generate a DLV set in addition to the key (DNSKEY) and DS sets. The domain is appended to the name of the records. -.TP -\-d \fIdirectory\fR -Look for -\fIkeyset\fR -files in -\fBdirectory\fR -as the directory -.TP -\-g -Generate DS records for child zones from keyset files. Existing DS records will be removed. -.TP -\-s \fIstart\-time\fR -Specify the date and time when the generated RRSIG records become valid. This can be either an absolute or relative time. An absolute start time is indicated by a number in YYYYMMDDHHMMSS notation; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000. A relative start time is indicated by +N, which is N seconds from the current time. If no -\fBstart\-time\fR -is specified, the current time minus 1 hour (to allow for clock skew) is used. -.TP -\-e \fIend\-time\fR -Specify the date and time when the generated RRSIG records expire. As with -\fBstart\-time\fR, an absolute time is indicated in YYYYMMDDHHMMSS notation. A time relative to the start time is indicated with +N, which is N seconds from the start time. A time relative to the current time is indicated with now+N. If no -\fBend\-time\fR -is specified, 30 days from the start time is used as a default. -.TP -\-f \fIoutput\-file\fR -The name of the output file containing the signed zone. The default is to append -\fI.signed\fR -to the input file. -.TP -\-h -Prints a short summary of the options and arguments to -\fBdnssec\-signzone\fR. -.TP -\-i \fIinterval\fR -When a previously signed zone is passed as input, records may be resigned. The -\fBinterval\fR -option specifies the cycle interval as an offset from the current time (in seconds). If a RRSIG record expires after the cycle interval, it is retained. Otherwise, it is considered to be expiring soon, and it will be replaced. -.sp -The default cycle interval is one quarter of the difference between the signature end and start times. So if neither -\fBend\-time\fR -or -\fBstart\-time\fR -are specified, -\fBdnssec\-signzone\fR -generates signatures that are valid for 30 days, with a cycle interval of 7.5 days. Therefore, if any existing RRSIG records are due to expire in less than 7.5 days, they would be replaced. -.TP -\-n \fIncpus\fR -Specifies the number of threads to use. By default, one thread is started for each detected CPU. -.TP -\-o \fIorigin\fR -The zone origin. If not specified, the name of the zone file is assumed to be the origin. -.TP -\-p -Use pseudo\-random data when signing the zone. This is faster, but less secure, than using real random data. This option may be useful when signing large zones or when the entropy source is limited. -.TP -\-r \fIrandomdev\fR -Specifies the source of randomness. If the operating system does not provide a -\fI/dev/random\fR -or equivalent device, the default source of randomness is keyboard input. -\fIrandomdev\fR -specifies the name of a character device or file containing random data to be used instead of the default. The special value -\fIkeyboard\fR -indicates that keyboard input should be used. -.TP -\-t -Print statistics at completion. -.TP -\-v \fIlevel\fR -Sets the debugging level. -.TP -\-z -Ignore KSK flag on key when determining what to sign. -.TP -zonefile -The file containing the zone to be signed. -.TP -key -The keys used to sign the zone. If no keys are specified, the default all zone keys that have private key files in the current directory. -.SH "EXAMPLE" -.PP -The following command signs the -\fBexample.com\fR -zone with the DSA key generated in the -\fBdnssec\-keygen\fR -man page.

It is essentially a stripped\-down, caching\-only name server that answers queries using the BIND 9 lightweight resolver protocol rather than the DNS protocol. -.PP -\fBlwresd\fR -listens for resolver queries on a UDP port on the IPv4 loopback interface, 127.0.0.1. This means that -\fBlwresd\fR -can only be used by processes running on the local machine. By default UDP port number 921 is used for lightweight resolver requests and responses. -.PP -Incoming lightweight resolver requests are decoded by the server which then resolves them using the DNS protocol. When the DNS lookup completes, -\fBlwresd\fR -encodes the answers in the lightweight resolver format and returns them to the client that made the request. -.PP -If -\fI/etc/resolv.conf\fR -contains any -\fBnameserver\fR -entries, -\fBlwresd\fR -sends recursive DNS queries to those servers. This is similar to the use of forwarders in a caching name server. If no -\fBnameserver\fR -entries are present, or if forwarding fails, -\fBlwresd\fR -resolves the queries autonomously starting at the root name servers, using a built\-in list of root server hints. -.SH "OPTIONS" -.TP -\-C \fIconfig\-file\fR -Use -\fIconfig\-file\fR -as the configuration file instead of the default, -\fI/etc/resolv.conf\fR. -.TP -\-d \fIdebug\-level\fR -Set the daemon's debug level to -\fIdebug\-level\fR. Debugging traces from -\fBlwresd\fR -become more verbose as the debug level increases. -.TP -\-f -Run the server in the foreground (i.e. do not daemonize). -.TP -\-g -Run the server in the foreground and force all logging to -\fIstderr\fR. -.TP -\-n \fI#cpus\fR -Create -\fI#cpus\fR -worker threads to take advantage of multiple CPUs. If not specified, -\fBlwresd\fR -will try to determine the number of CPUs present and create one thread per CPU.

This allows resource records to be added or removed from a zone without manually editing the zone file. A single update request can contain requests to add or remove more than one resource record. -.PP -Zones that are under dynamic control via -\fBnsupdate\fR -or a DHCP server should not be edited by hand. Manual edits could conflict with dynamic updates and cause data to be lost. -.PP -The resource records that are dynamically added or removed with -\fBnsupdate\fR -have to be in the same zone. Requests are sent to the zone's master server. This is identified by the MNAME field of the zone's SOA record. -.PP -The -\fB\-d\fR -option makes -\fBnsupdate\fR -operate in debug mode. This provides tracing information about the update requests that are made and the replies received from the name server. -.PP -Transaction signatures can be used to authenticate the Dynamic DNS updates. These use the TSIG resource record type described in RFC2845 or the SIG(0) record described in RFC3535 and RFC2931. TSIG relies on a shared secret that should only be known to -\fBnsupdate\fR -and the name server. Currently, the only supported encryption algorithm for TSIG is HMAC\-MD5, which is defined in RFC 2104. Once other algorithms are defined for TSIG, applications will need to ensure they select the appropriate algorithm as well as the key when authenticating each other. For instance suitable -\fBkey\fR -and -\fBserver\fR -statements would be added to -\fI/etc/named.conf\fR -so that the name server can associate the appropriate secret key and algorithm with the IP address of the client application that will be using TSIG authentication. SIG(0) uses public key cryptography. To use a SIG(0) key, the public key must be stored in a KEY record in a zone served by the name server. -\fBnsupdate\fR -does not read -\fI/etc/named.conf\fR. -.PP -\fBnsupdate\fR -uses the -\fB\-y\fR -or -\fB\-k\fR -option (with an HMAC\-MD5 key) to provide the shared secret needed to generate a TSIG record for authenticating Dynamic DNS update requests. These options are mutually exclusive. With the -\fB\-k\fR -option, -\fBnsupdate\fR -reads the shared secret from the file -\fIkeyfile\fR, whose name is of the form -\fIK{name}.+157.+{random}.private\fR. For historical reasons, the file -\fIK{name}.+157.+{random}.key\fR -must also be present. When the -\fB\-y\fR -option is used, a signature is generated from -\fIkeyname:secret.\fR\fIkeyname\fR -is the name of the key, and -\fIsecret\fR -is the base64 encoded shared secret. Use of the -\fB\-y\fR -option is discouraged because the shared secret is supplied as a command line argument in clear text. This may be visible in the output from -\fBps\fR(1 ) -or in a history file maintained by the user's shell. -.PP -The -\fB\-k\fR -may also be used to specify a SIG(0) key used to authenticate Dynamic DNS update requests. In this case, the key specified is not an HMAC\-MD5 key. -.PP -By default -\fBnsupdate\fR -uses UDP to send update requests to the name server unless they are too large to fit in a UDP request in which case TCP will be used. The -\fB\-v\fR -option makes -\fBnsupdate\fR -use a TCP connection. This may be preferable when a batch of update requests is made. -.PP -The -\fB\-t\fR -option sets the maximum time a update request can take before it is aborted. The default is 300 seconds. Zero can be used to disable the timeout. -.PP -The -\fB\-u\fR -option sets the UDP retry interval. The default is 3 seconds. If zero the interval will be computed from the timeout interval and number of UDP retries. -.PP -The -\fB\-r\fR -option sets the number of UDP retries. The default is 3. If zero only one update request will be made. -.SH "INPUT FORMAT" -.PP -\fBnsupdate\fR -reads input from -\fIfilename\fR -or standard input. Each command is supplied on exactly one line of input. Some commands are for administrative purposes. The others are either update instructions or prerequisite checks on the contents of the zone. These checks set conditions that some name or set of resource records (RRset) either exists or is absent from the zone. These conditions must be met if the entire update request is to succeed. Updates will be rejected if the tests for the prerequisite conditions fail. -.PP -Every update request consists of zero or more prerequisites and zero or more updates. This allows a suitably authenticated update request to proceed if some specified resource records are present or missing from the zone. A blank input line (or the -\fBsend\fR -command) causes the accumulated commands to be sent as one Dynamic DNS update request to the name server. -.PP -The command formats and their meaning are as follows: -.TP -.HP 7 \fBserver\fR {servername} [port] -Sends all dynamic update requests to the name server -\fIservername\fR. When no server statement is provided, -\fBnsupdate\fR -will send updates to the master server of the correct zone. The MNAME field of that zone's SOA record will identify the master server for that zone. -\fIport\fR -is the port number on -\fIservername\fR -where the dynamic update requests get sent. If no port number is specified, the default DNS port number of 53 is used. -.TP -.HP 6 \fBlocal\fR {address} [port] -Sends all dynamic update requests using the local -\fIaddress\fR. When no local statement is provided, -\fBnsupdate\fR -will send updates using an address and port chosen by the system. -\fIport\fR -can additionally be used to make requests come from a specific port. If no port number is specified, the system will assign one. -.TP -.HP 5 \fBzone\fR {zonename} -Specifies that all updates are to be made to the zone -\fIzonename\fR. If no -\fIzone\fR -statement is provided, -\fBnsupdate\fR -will attempt determine the correct zone to update based on the rest of the input. -.TP -.HP 6 \fBclass\fR {classname} -Specify the default class. If no -\fIclass\fR -is specified the default class is -\fIIN\fR. -.TP -.HP 4 \fBkey\fR {name} {secret} -Specifies that all updates are to be TSIG signed using the -\fIkeyname\fR\fIkeysecret\fR -pair. The -\fBkey\fR -command overrides any key specified on the command line via -\fB\-y\fR -or -\fB\-k\fR. -.TP -.HP 16 \fBprereq nxdomain\fR {domain\-name} -Requires that no resource record of any type exists with name -\fIdomain\-name\fR. -.TP -.HP 16 \fBprereq yxdomain\fR {domain\-name} -Requires that -\fIdomain\-name\fR -exists (has as at least one resource record, of any type). -.TP -.HP 15 \fBprereq nxrrset\fR {domain\-name} [class] {type} -Requires that no resource record exists of the specified -\fItype\fR, -\fIclass\fR -and -\fIdomain\-name\fR.

If there are, the update request fails. If this name does not exist, a CNAME for it is added. This ensures that when the CNAME is added, it cannot conflict with the long\-standing rule in RFC1034 that a name must not exist as any other record type if it exists as a CNAME.

It supersedes the -\fBndc\fR -utility that was provided in old BIND releases. If -\fBrndc\fR -is invoked with no command line options or arguments, it prints a short summary of the supported commands and the available options and their arguments. -.PP -\fBrndc\fR -communicates with the name server over a TCP connection, sending commands authenticated with digital signatures. In the current versions of -\fBrndc\fR -and -\fBnamed\fR -named the only supported authentication algorithm is HMAC\-MD5, which uses a shared secret on each end of the connection. This provides TSIG\-style authentication for the command request and the name server's response. All commands sent over the channel must be signed by a key_id known to the server. -.PP -\fBrndc\fR -reads a configuration file to determine how to contact the name server and decide what algorithm and key it should use. -.SH "OPTIONS" -.TP -\-c \fIconfig\-file\fR -Use -\fIconfig\-file\fR -as the configuration file instead of the default, -\fI/etc/rndc.conf\fR. -.TP -\-k \fIkey\-file\fR -Use -\fIkey\-file\fR -as the key file instead of the default, -\fI/etc/rndc.key\fR. The key in -\fI/etc/rndc.key\fR -will be used to authenticate commands sent to the server if the -\fIconfig\-file\fR -does not exist. -.TP -\-s \fIserver\fR -\fIserver\fR -is the name or address of the server which matches a server statement in the configuration file for -\fBrndc\fR. If no server is supplied on the command line, the host named by the default\-server clause in the option statement of the configuration file will be used. -.TP -\-p \fIport\fR -Send commands to TCP port -\fIport\fR -instead of BIND 9's default control channel port, 953. -.TP -\-V -Enable verbose logging. -.TP -\-y \fIkeyid\fR -Use the key -\fIkeyid\fR -from the configuration file. -\fIkeyid\fR -must be known by named with the same algorithm and secret string in order for control message validation to succeed. If no -\fIkeyid\fR -is specified, -\fBrndc\fR -will first look for a key clause in the server statement of the server being used, or if no server statement is present for that host, then the default\-key clause of the options statement. Note that the configuration file contains shared secrets which are used to send authenticated control commands to name servers. It should therefore not have general read or write access. -.PP -For the complete set of commands supported by -\fBrndc\fR, see the BIND 9 Administrator Reference Manual or run -\fBrndc\fR -without arguments to see its help message. -.SH "LIMITATIONS" -.PP -\fBrndc\fR -does not yet support all the commands of the BIND 8 -\fBndc\fR -utility. -.PP -There is currently no way to provide the shared secret for a -\fBkey_id\fR -without using the configuration file. -.PP -Several error messages could be clearer. -.SH "SEE ALSO" -.PP -\fBrndc.conf\fR(5), -\fBnamed\fR(8), -\fBnamed.conf\fR(5)\fBndc\fR(8), -BIND 9 Administrator Reference Manual. -.SH "AUTHOR" -.PP -Internet Systems Consortium diff --git a/contrib/bind9/bin/rndc/rndc.c b/contrib/bind9/bin/rndc/rndc.c deleted file mode 100644 index 63e8f23b9ff5..000000000000 --- a/contrib/bind9/bin/rndc/rndc.c +++ /dev/null @@ -1,688 +0,0 @@ -/* - * Copyright (C) 2004, 2005 Internet Systems Consortium, Inc.
