-@(#) $Header: /tcpdump/master/libpcap/INSTALL,v 1.46 2000/12/16 09:05:11 guy Exp $ (LBL)
-
-To build libpcap, run "./configure" (a shell script). The configure
-script will determine your system attributes and generate an
-appropriate Makefile from Makefile.in. Next run "make". If everything
-goes well you can su to root and run "make install". However, you need
-not install libpcap if you just want to build tcpdump; just make sure
-the tcpdump and libpcap directory trees have the same parent
-directory.
-
-If configure says:
-
-    configure: warning: cannot determine packet capture interface
-    configure: warning: (see INSTALL for more info)
-
-then your system either does not support packet capture or your system
-does support packet capture but libpcap does not support that
-particular type. (If you have HP-UX, see below.) If your system uses a
-packet capture not supported by libpcap, please send us patches; don't
-forget to include an autoconf fragment suitable for use in
-configure.in.
-
-It is possible to override the default packet capture type, although
-the circumstance where this works are limited. For example if you have
-installed bpf under SunOS 4 and wish to build a snit libpcap:
-
-    ./configure --with-pcap=snit
-
-Another example is to force a supported packet capture type in the case
-where the configure scripts fails to detect it.
-
-You will need an ANSI C compiler to build libpcap. The configure script
-will abort if your compiler is not ANSI compliant. If this happens, use
-the GNU C compiler, available via anonymous ftp:
-
-	ftp://ftp.gnu.org/pub/gnu/gcc/
-
-If you use flex, you must use version 2.4.6 or higher. The configure
-script automatically detects the version of flex and will not use it
-unless it is new enough. You can use "flex -V" to see what version you
-have (unless it's really old). The current version of flex is available
-via anonymous ftp:
-
-	ftp://ftp.ee.lbl.gov/flex-*.tar.Z
-
-As of this writing, the current version is 2.5.4.
-
-If you use bison, you must use flex (and visa versa). The configure
-script automatically falls back to lex and yacc if both flex and bison
-are not found.
-
-Sometimes the stock C compiler does not interact well with flex and
-bison. The list of problems includes undefined references for alloca.
-You can get around this by installing gcc or manually disabling flex
-and bison with:
-
-    ./configure --without-flex --without-bison
-
-If your system only has AT&T lex, this is okay unless your libpcap
-program uses other lex/yacc generated code. (Although it's possible to
-map the yy* identifiers with a script, we use flex and bison so we
-don't feel this is necessary.)
-
-Some systems support the Berkeley Packet Filter natively; for example
-out of the box OSF and BSD/OS have bpf. If your system does not support
-bpf, you will need to pick up:
-
-	ftp://ftp.ee.lbl.gov/bpf-*.tar.Z
-
-Note well: you MUST have kernel source for your operating system in
-order to install bpf. An exception is SunOS 4; the bpf distribution
-includes replacement kernel objects for some of the standard SunOS 4
-network device drivers. See the bpf INSTALL document for more
-information.
-
-If you use Solaris, there is a bug with bufmod(7) that is fixed in
-Solaris 2.3.2 (aka SunOS 5.3.2). Setting a snapshot length with the
-broken bufmod(7) results in data be truncated from the FRONT of the
-packet instead of the end.  The work around is to not set a snapshot
-length but this results in performance problems since the entire packet
-is copied to user space. If you must run an older version of Solaris,
-there is a patch available from Sun; ask for bugid 1149065. After
-installing the patch, use "setenv BUFMOD_FIXED" to enable use of
-bufmod(7). However, we recommend you run a more current release of
-Solaris.
-
-If you use the SPARCompiler, you must be careful to not use the
-/usr/ucb/cc interface. If you do, you will get bogus warnings and
-perhaps errors. Either make sure your path has /opt/SUNWspro/bin
-before /usr/ucb or else:
-
-    setenv CC /opt/SUNWspro/bin/cc
-
-before running configure. (You might have to do a "make distclean"
-if you already ran configure once).
-
-Also note that "make depend" won't work; while all of the known
-universe uses -M, the SPARCompiler uses -xM to generate makefile
-dependencies.
-
-If you are trying to do packet capture with a FORE ATM card, you may or
-may not be able to. They usually only release their driver in object
-code so unless their driver supports packet capture, there's not much
-libpcap can do.
-
-If you get an error like:
-
-    tcpdump: recv_ack: bind error 0x???
-
-when using DLPI, look for the DL_ERROR_ACK error return values, usually
-in /usr/include/sys/dlpi.h, and find the corresponding value.
-
-Under {DEC OSF/1, Digital UNIX, Tru64 UNIX}, packet capture must be
-enabled before it can be used.  For instructions on how to enable packet
-filter support, see:
-
-	ftp://ftp.digital.com/pub/Digital/dec-faq/Digital-UNIX
-
-Look for the "How do I configure the Berkeley Packet Filter and capture
-tcpdump traces?" item.
-
-Once you enable packet filter support, your OSF system will support bpf
-natively.
-
-Under Ultrix, packet capture must be enabled before it can be used. For
-instructions on how to enable packet filter support, see:
-
-	ftp://ftp.digital.com/pub/Digital/dec-faq/ultrix
-
-If you use HP-UX, you must have at least version 9 and either the
-version of cc that supports ANSI C (cc -Aa) or else use the GNU C
-compiler. You must also buy the optional streams package. If you don't
-have:
-
-    /usr/include/sys/dlpi.h
-    /usr/include/sys/dlpi_ext.h
-
-then you don't have the streams package. In addition, we believe you
-need to install the "9.X LAN and DLPI drivers cumulative" patch
-(PHNE_6855) to make the version 9 DLPI work with libpcap.
-
-The DLPI streams package is standard starting with HP-UX 10.
-
-The HP implementation of DLPI is a little bit eccentric. Unlike
-Solaris, you must attach /dev/dlpi instead of the specific /dev/*
-network pseudo device entry in order to capture packets. The PPA is
-based on the ifnet "index" number. Under HP-UX 9, it is necessary to
-read /dev/kmem and the kernel symbol file (/hp-ux). Under HP-UX 10,
-DLPI can provide information for determining the PPA. It does not seem
-to be possible to trace the loopback interface. Unlike other DLPI
-implementations, PHYS implies MULTI and SAP and you get an error if you
-try to enable more than one promiscuous mode at a time.
-
-It is impossible to capture outbound packets on HP-UX 9.  To do so on
-HP-UX 10, you will, apparently, need a late "LAN products cumulative
-patch" (at one point, it was claimed that this would be PHNE_18173 for
-s700/10.20; at another point, it was claimed that the required patches
-were PHNE_20892, PHNE_20725 and PHCO_10947, or newer patches), and to do
-so on HP-UX 11 you will, apparently, need the latest lancommon/DLPI
-patches and the latest driver patch for the interface(s) in use on HP-UX
-11 (at one point, it was claimed that patches PHNE_19766, PHNE_19826,
-PHNE_20008, and PHNE_20735 did the trick).
-
-Furthermore, on HP-UX 10, you will need to turn on a kernel switch by
-doing
-
-	echo 'lanc_outbound_promisc_flag/W 1' | adb -w /stand/vmunix /dev/mem
-
-You would have to arrange that this happen on reboots; the right way to
-do that would probably be to put it into an executable script file
-"/sbin/init.d/outbound_promisc" and making
-"/sbin/rc2.d/S350outbound_promisc" a symbolic link to that script.
-
-Finally, testing shows that there can't be more than one simultaneous
-DLPI user per network interface.
-
-If you use Linux, this version of libpcap is known to compile and run
-under Red Hat 4.0 with the 2.0.25 kernel.  It may work with earlier 2.X
-versions but is guaranteed not to work with 1.X kernels.  Running more
-than one libpcap program at a time, on a system with a 2.0.X kernel, can
-cause problems since promiscuous mode is implemented by twiddling the
-interface flags from the libpcap application; the packet capture
-mechanism in the 2.2 and later kernels doesn't have this problem.  Also,
-packet timestamps aren't very good.  This appears to be due to haphazard
-handling of the timestamp in the kernel.
-
-Note well: there is rumoured to be a version of tcpdump floating around
-called 3.0.3 that includes libpcap and is supposed to support Linux. 
-You should be advised that neither the Network Research Group at LBNL
-nor the Tcpdump Group ever generated a release with this version number. 
-The LBNL Network Research Group notes with interest that a standard
-cracker trick to get people to install trojans is to distribute bogus
-packages that have a version number higher than the current release. 
-They also noted with annoyance that 90% of the Linux related bug reports
-they got are due to changes made to unofficial versions of their page. 
-If you are having trouble but aren't using a version that came from
-tcpdump.org, please try that before submitting a bug report!
-
-On Linux, libpcap will not work if the kernel does not have the packet
-socket option enabled; see the README.linux file for information about
-this.
-
-If you use AIX, you may not be able to build libpcap from this release.
-libpcap. We do not have an AIX system in house so it's impossible for
-us to test AIX patches submitted to us. We are told that you must link
-against /lib/pse.exp, that you must use AIX cc or a GNU C compiler
-newer than 2.7.2 and that you may need to run strload before running a
-libpcap application.
-
-Read the README.aix file for information on installing libpcap and
-configuring your system to be able to support libpcap.
-
-If you use NeXTSTEP, you will not be able to build libpcap from this
-release. We hope to support this operating system in some future
-release of libpcap.
-
-If you use SINIX, you should be able to build libpcap from this
-release. It is known to compile and run on SINIX-Y/N 5.42 with the C-DS
-V1.0 or V1.1 compiler. But note that in some releases of SINIX, yacc
-emits incorrect code; if grammar.y fails to compile, change every
-occurence of:
-
-	#ifdef YYDEBUG
-
-to:
-	#if YYDEBUG
-
-Another workaround is to use flex and bison.
-
-If you use SCO, you might have trouble building libpcap from this
-release. We do not have a machine running SCO and have not had reports
-of anyone successfully building on it. Since SCO apparently supports
-DLPI, it's possible the current version works. Meanwhile, SCO provides
-a tcpdump binary as part of their "Network/Security Tools" package:
-
-    http://www.sco.com/technology/internet/goodies/#SECURITY
-
-There is also a README that explains how to enable packet capture.
-
-If you use UnixWare, you will not be able to build libpcap from this
-release. We hope to support this operating system in some future
-release of libpcap. Meanwhile, there appears to be an UnixWare port of
-libpcap 0.0 (and tcpdump 3.0) in:
-
-    ftp://ftp1.freebird.org/pub/mirror/freebird/internet/systools/
-
-UnixWare appears to use a hacked version of DLPI.
-
-If linking tcpdump fails with "Undefined: _alloca" when using bison on
-a Sun4, your version of bison is broken. In any case version 1.16 or
-higher is recommended (1.14 is known to cause problems 1.16 is known to
-work). Either pick up a current version from:
-
-	ftp://ftp.gnu.org/pub/gnu/bison
-
-or hack around it by inserting the lines:
-
-	#ifdef __GNUC__
-	#define alloca __builtin_alloca
-	#else
-	#ifdef sparc
-	#include <alloca.h>
-	#else
-	char *alloca ();
-	#endif
-	#endif
-
-right after the (100 line!) GNU license comment in bison.simple, remove
-grammar.[co] and fire up make again.
-
-If you use SunOS 4, your kernel must support streams NIT. If you run a
-libpcap program and it dies with:
-
-    /dev/nit: No such device
-
-You must add streams NIT support to your kernel configuration, run
-config and boot the new kernel.
-
-If you are running a version of SunOS earlier than 4.1, you will need
-to replace the Sun supplied /sys/sun{3,4,4c}/OBJ/nit_if.o with the
-appropriate version from this distribution's SUNOS4 subdirectory and
-build a new kernel:
-
-	nit_if.o.sun3-sunos4		(any flavor of sun3)
-	nit_if.o.sun4c-sunos4.0.3c	(SS1, SS1+, IPC, SLC, etc.)
-	nit_if.o.sun4-sunos4		(Sun4's not covered by
-					    nit_if.o.sun4c-sunos4.0.3c)
-
-These nit replacements fix a bug that makes nit essentially unusable in
-pre-SunOS 4.1.  In addition, our sun4c-sunos4.0.3c nit gives you
-timestamps to the resolution of the SS-1 clock (1 us) rather than the
-lousy 20ms timestamps Sun gives you  (tcpdump will print out the full
-timestamp resolution if it finds it's running on a SS-1).
