v0.4 Sat Jul 25 12:40:09 PDT 1998
- Fix endian problem with DLT_NULL devices. From FreeBSD via Bill
Fenner (fenner@parc.xerox.com)
- Fix alignment problem with FDDI under DLPI. This was causing core
dumps under Solaris.
- Added configure options to disable flex and bison. Resulted from a
bug report by barnett@grymoire.crd.ge.com (Bruce Barnett). Also added
options to disable gcc and to force a particular packet capture type.
- Added support for Fore ATM interfaces (qaa and fa) under IRIX. Thanks
to John Hawkinson (jhawk@mit.edu)
- Change Linux PPP and SLIP to use DLT_RAW since the kernel does not
supply any "link layer" data.
- Change Linux to use SIOCGIFHWADDR ioctl to determine link layer type.
Thanks to Thomas Sailer (sailer@ife.ee.ethz.ch)
- Change IRIX PPP to use DLT_RAW since the kernel does not supply any
"link layer" data.
- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
formats.
- Added some new SGI snoop interface types. Thanks to Steve Alexander
(sca@refugee.engr.sgi.com)
- Fixes for HP-UX 10.20 (which is similar to HP-UX 9). Thanks to
Richard Allen (ra@hp.is) and Steinar Haug (sthaug@nethelp.no)
- Fddi supports broadcast as reported by Jeff Macdonald
(jeff@iacnet.com). Also correct ieee802 and arcnet.
- Determine Linux pcap buffer size at run time or else it might not be
big enough for some interface types (e.g. FDDI). Thanks to Jes
Sorensen (Jes.Sorensen@cern.ch)
- Fix some linux alignment problems.
- Document promisc argument to pcap_open_live(). Reported by Ian Marsh
(ianm@sics.se)
- Support Metricom radio packets under Linux. Thanks to Kevin Lai
(laik@gunpowder.stanford.edu)
- Bind to interface name under Linux to avoid packets from multiple
interfaces on multi-homed hosts. Thanks to Kevin Lai
(laik@gunpowder.stanford.edu)
- Change L_SET to SEEK_SET for HP-UX. Thanks to Roland Roberts
(rroberts@muller.com)
- Fixed an uninitialized memory reference found by Kent Vander Velden
(graphix@iastate.edu)
- Fixed lex pattern for IDs to allow leading digits. As reported by
Theo de Raadt (deraadt@cvs.openbsd.org)
- Fixed Linux include file problems when using GNU libc.
- Ifdef ARPHRD_FDDI since not all versions of the Linux kernel have it.
Reported reported by Eric Jacksch (jacksch@tenebris.ca)
- Fixed bug in pcap_dispatch() that kept it from returning on packet
timeouts.
- Changed ISLOOPBACK() macro when IFF_LOOPBACK isn't available to check
for "lo" followed by an eos or digit (newer versions of Linux
apparently call the loopback "lo" instead of "lo0").
- Fixed Linux networking include files to use ints instead of longs to
avoid problems with 64 bit longs on the alpha. Thanks to Cristian
Gafton (gafton@redhat.com)

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:

If you are trying to do packet capture with a FORE ATM card, you may or

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.

workaround is to use:

dnl This test is for network applications that need socket() and
dnl gethostbyname() -ish functions. Under Solaris, those applications
dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
dnl with "-lnsl" but should *not* link with "-lsocket" because
dnl libsocket.a breaks a number of things (for instance:
dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
dnl versions of IRIX).
dnl
dnl Unfortunately, many application developers are not aware of this,
dnl and mistakenly write tests that cause -lsocket to be used under
dnl IRIX. It is also easy to write tests that cause -lnsl to be used
dnl under operating systems where neither are necessary (or useful),
dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
dnl
dnl This test exists so that every application developer does not test
dnl this in a different, and subtly broken fashion.
dnl It has been argued that this test should be broken up into two
dnl seperate tests, one for the resolver libraries, and one for the
dnl libraries necessary for using Sockets API. Unfortunately, the two
dnl are carefully intertwined and allowing the autoconf user to use
dnl them independantly potentially results in unfortunate ordering
dnl dependancies -- as such, such component macros would have to
dnl carefully use indirection and be aware if the other components were
dnl executed. Since other autoconf macros do not go to this trouble,
dnl and almost no applications use sockets without the resolver, this
dnl complexity has not been implemented.
dnl
dnl The check for libresolv is in case you are attempting to link
dnl statically and happen to have a libresolv.a lying around (and no
dnl libnsl.a).
