v3.4 Sat Jul 25 12:40:55 PDT 1998
- Hardwire Linux slip support since it's too hard to detect.
- Redo configuration of "network" libraries (-lsocket and -lnsl) to
deal with IRIX. Thanks to John Hawkinson (jhawk@mit.edu)
- Added -a which tries to translate network and broadcast addresses to
names. Suggested by Rob van Nieuwkerk (robn@verdi.et.tudelft.nl)
- Added a configure option to disable gcc.
- Added a "raw" packet printer.
- Not having an interface address is no longer fatal. Requested by John
Hawkinson.
- Rework signal setup to accommodate Linux.
- OSPF truncation check fix. Also display the type of OSPF packets
using MD5 authentication. Thanks to Brian Wellington
(bwelling@tis.com)
- Fix truncation check bugs in the Kerberos printer. Reported by Ezra
Peisach (epeisach@mit.edu)
- Don't catch SIGHUP when invoked with nohup(1). Thanks to Dave Plonka
(plonka@mfa.com)
- Specify full install target as a way of detecting if install
directory does not exist. Thanks to Dave Plonka.
- Bit-swap FDDI addresses for BSD/OS too. Thanks to Paul Vixie
(paul@vix.com)
- Fix off-by-one bug when testing size of ethernet packets. Thanks to
Marty Leisner (leisner@sdsp.mc.xerox.com)
- Add a local autoconf macro to check for routines in libraries; the
autoconf version is broken (it only puts the library name in the
cache variable name). Thanks to John Hawkinson.
- Add a local autoconf macro to check for types; the autoconf version
is broken (it uses grep instead of actually compiling a code fragment).
- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
formats.
- Extend OSF ip header workaround to versions 1 and 2.
- Fix some signed problems in the nfs printer. As reported by David
Sacerdote (davids@silence.secnet.com)
- Detect group wheel and use it as the default since BSD/OS' install
can't hack numeric groups. Reported by David Sacerdote.
- AIX needs special loader options. Thanks to Jonathan I. Kamens
(jik@cam.ov.com)
- Fixed the nfs printer to print port numbers in decimal. Thanks to
Kent Vander Velden (graphix@iastate.edu)
- Find installed libpcap in /usr/local/lib when not using gcc.
- Disallow network masks with non-network bits set.
- Attempt to detect "egcs" versions of gcc.
- Add missing closing double quotes when displaying bootp strings.
Reported by Viet-Trung Luu (vluu@picard.math.uwaterloo.ca)

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.
If you use OSF 4, note that that there appears to be some serious bugs
with the stock C compiler. The configure code fragments that detect if
the ether_header and ether_arp structs use the ether_addr struct

Some tools for viewing and analyzing tcpdump trace files are available
from the Internet Traffic Archive:
http://town.hall.org/Archives/pub/ITA/
http://www.acm.org/sigcomm/ITA/
Another tool that tcpdump users might find useful is tcpslice:
ftp://ftp.ee.lbl.gov/tcpslice.tar.Z
It is a program that can be used to extract portions of tcpdump binary
trace files. See the above distribution for further details and
documentation.
