Was wondering - you wouldn't by chance be running with a filter via the "-F" runtime switch (or "config bpf_file" in snort.conf), would you? -- Shane Castle Data Security Mgr, Boulder County IT -----Original Message----- From: Y M [mailto:snort () outlook com] Sent: Monday, December 10, 2012 10:29 To: Lay, James; snort-users () lists sourceforge net Subject: Re: [Snort-users] No TCP alerts, only UDP and ICMP Hi Lay, Sorry for my late reply. I wouldn't be able to provide a pcap file, at least for now. However, I tried that in Snort, using the -K pcap (I also tried the -b switch) and read that through tcpdump, and I only got UDP packets, with some ICMPs. Running Snort in verbose mode shows that the majority of the traffic is in fact TCP. Thanks.

I also tried/compared with previously working conf files, conf file in the tarball, and the conf file from Snort labs but the behavior remained the same across all configurations. Thanks.

I did try with -k none as suggested and I'm getting the same results, no TCP alerts, just UDP and ICMP. ________________________________ From: Marcos Rodriguez <mailto:marcos.e.rodriguez () gmail com> Sent: 12/10/2012 5:50 PM To: Y M <mailto:snort () outlook com> Cc: snort-users () lists sourceforge net Subject: Re: [Snort-users] No TCP alerts, only UDP and ICMP Hi YM, Could you try again by adding '-k none' please? ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
