Hrm. I just grabbed the latest snort beta tarball, and it's coring as well. But at least it does it within a few minutes.
It crashes on linux also. change conf file to use stream2. That should delay the the crash somewhat. Remember this is beta TEST mode, there are a number of areas in the code where ifdef DEBUG's have not been inserted. I've also seen problems with defrag, but have not gotten any confirmation. It is my experience that certain fragment sequences in conjunction with some unknown force cause the creation of mutant packets, that is: IP: proto=icmp (20 byte header) DATA from somewhere in snort memory (not another incoming packet) Makes for some real weird ICMP type / code packets if you are looking for that sort of thing. Later,
Upon startup, I get hundreds of "freeing AVL node" messages and then after about a minute or so snort complains that "max nodes reach, data is not inserted" after which it segfaults and dumps core.
This is all stream3 stuff.
Whee.

Running it in the foreground (no -D), it complains of a Bus Error. Checking other projects' lists, I noticed some complaints about the optimization routines in gcc 2.95.x on Solaris producing similar problems, so I compiled snort with -O0 (no optimization), rather than the default -O2. It's been running for over two hours now without coring, so I think that this might have done the trick.

Unfortunately, itdumps coreafter running for some time (usually 30-120 minutes). I'm using 'snort -Afull -c snort.conf -l /snort -d -D' to invoke snort. Is anyone aware of any issues with snort & Solaris 8, andifso, of any workarounds? Thanks! Tom -- Thomas A.
