Re: [tcpdump-workers] compilation status of current (2004-09-13)
What is LIBOBJS defined as in the top-level Makefile? If it's defined as anything that includes "datalinks.o", try doing a "make distclean", re-running configure, and trying again. no datalinks.o: LOCALSRC = print-smb.c smbutil.c GENSRC = version.c LIBOBJS = strlcat$U.o strlcpy$U.o strsep$U.o rick jones - This is the tcpdump-workers list.

A: Linux is the primary platform for the DAG product range, with robust support. A device driver and toolset is currently under development for FreeBSD, with a common user API. We have no plans to support other operating systems at this time." The Endace people have contributed DAG support to libpcap for both Linux and FreeBSD. - This is the tcpdump-workers list.

If "look at" implies "dissect as NFS", Ethereal or Tethereal might be the way to go (they can reassemble NFS-over-TCP if you turn on the right preferences - and can also reassemble fragmented IP datagrams for NFS-over-UDP), and they also handle multiple messages in a segment. Bonus :) That is what I was seeking. thanks, rick - This is the tcpdump-workers list. Visit https://lists.sandelman.ca/ to unsubscribe.
