Thanks in advance for pointing me to right place/giving presentation Regards Viswanathan R --- On Mon, 9/15/08, snort-users-request () lists sourceforge net <snort-users-request () lists sourceforge net> wrote:

Check those out. Joel On Sep 10, 2008, at 8:24 PM, Nix Hanwei wrote:Hi Gurus, I'm new to here. I had encounter the following problem while installing snorts. Please assist me here.

Paul, Obviously.. IT IS NOT OBVIOUS since I'm asking for help. I did not assign the PORTVAR variable with/to "ANY". I do the normal routine of pushing VRT rules that has worked before and I did not do anything special this time other than review and uncomment a few rules that the VRT team commented. I also did NOT modify the snort.conf, which I may add... the same snort.conf file (that's been working) that I've been using for a while now! Magic fix... removed previously tar'd dirs, untarred it again, and somehow it's good to go. Somehow something got corrupted and since doing an egrep for PORTVAR didn't show squat and I need the stuff to be up, I had to just redo the procedure and push each categorized rule[s] one at a time (hoping it will at least point me to a rule that was syntactically incorrect) -- which fortunately it didn't.

FATAL ERROR: ***Rule--PortVar Parse error:(pos=4,error=not a number)ANY >> ^Anybody run into this? Better yet, how to fix it?It's pretty obvious, isn't it? You can'tuse "ANY" as the value ofPORTVAR. It must be a number or number, comma or dashseparated.Somewhere in the snort.conf file there is a line withthe following:PORTVAR = ANY That line is invalid. Paul Schmehl As if it wasn't already obvious, my opinions are my own and not those of my employer.-------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ Message: 4 Date: Sat, 13 Sep 2008 07:56:04 -0600 From: James Lay <jlay () slave-tothe-box net> Subject: [Snort-users] Snort on Leopard 10.5.4...getting there To: Snort <snort-users () lists sourceforge net> Message-ID: <C4F12294.39A48%jlay () slave-tothe-box net> Content-Type: text/plain; charset="iso-8859-1" So I?ve got snort 2.8.3 running right now on Leo 10.5.4 (YaY).

As for the snort.conf, I had to comment out all the dynamic preprocessor jazz to get it to run without a Bus Error: #dynamicpreprocessor directory /usr/snort/lib/snort_dynamicpreprocessor/ #dynamicengine /usr/snort/lib/snort_dynamicengine/libsf_engine.dylib #dynamicdetection directory /usr/snort/lib/snort_dynamicrule/ and the dns, smtp, dce, and telnet/ftp dynamic preprocessors. Once that was done it came up with no error. I'll look through the BUGS and send along, but here's some of the info from the crash file: Process: snort [72780] Path: /usr/snort/bin/snort Identifier: snort Version: ??? (???)
