As I continue to get tons of requests for my patches, and tons of questions about them, let me try to answer them again. I have taken the code written by Van Jacobson and others at Lawrence Berkeley Labs called tcpdump and modified it to run under SunOS4.0. The original code only ran under SunOS3.5. This code can run only on Sun's and has not been tested by me (or anyone else that I know) on anything other that Sun-3's. In order for the program to run properly under SunOS4.0, a kernel fix is needed to repair the broken NIT interface. Sun can supply you with a new nit_if.o. If this object is not incorporated into the kernel, it will appear as if you are receiving duplicate ethernet packets. This is because the bug manifests itself by making all of the snapshots in each chunk identical. I have been informed by Marc Lavine of 3Com (marcl@vax.spd.3com.com) that the program dumps core when decoding arp packets. I don't know if my diffs are causing this or if the problem occurs with the old version, but if I get a chance I will attempt to find the problem... So please use this stuff at your own risk. For those of you still trying to get this stuff, the following is a list of sites that I know of (there may be others...): ftp.ee.lbl.gov original sources for Sun-3's running SunOS3.5 devvax.tn.cornell.edu patches to sources for SunOS4.0 titan.rice.edu binaries for Sun-3's running SunOS3.5 ncar.ucar.edu binaries for Sun-3's running SunOS4.0 The four sites listed above all provide anonymous ftp service, and titan.rice.edu provides mail archive retrieval service, but I'm not sure of the specifics. Please try to retrieve the things that you need from these sites before sending a note to me. And please do not ask me to mail the original sources, please try a near neighbor first. If you have questions other than requests, I'd be happy to hear from you (especially if you fixed the problem with the arp decoding). Good Luck Micky arpa: micky@cunixc.cc.columbia.edu uucp: ...!rutgers!columbia!cunixc!micky bitnet: malua@cuvmc

I came in late to this conversation, so forgive any redundant information. The etherfind in SunOS 4.0 has been enhanced to provide most of the features of tcpdump. -- Bruce G.
