Were you able to resolve the problem? Span port configuration is a common mistake. No problem. Joel On Wed, Jan 26, 2011 at 10:41 AM, Crusty Saint <saintcrusty () gmail com>wrote:
I confess, the span port was not positioned properly. 2011/1/11 Crusty Saint <saintcrusty () gmail com> Same for overlapping tcp packets, with any threshold but 0( this is on a cisco switch with span/monitor port active ) 2011/1/11 Joel Esler <jesler () sourcefire com> Okay, so let me ask you guys. What can we do (Snort) to make it better?Joel On Mon, Jan 10, 2011 at 8:54 PM, Martin Holste <mcholste () gmail com>wrote:I've never found the alerts generated by the FTP preproc to be helpful for anything other than a heartbeat to prove Snort is up and sniffing traffic. I recently started to suppress all from that gen_id. I'm strongly considering doing the same for the SSL preproc. The amount of resources it takes to investigate each false positive is not worth the off-chance that you will be the one to discover a never-before-seen new FTP/telnet hack.

Any recommendations on associating an ftp command channel with an ftp passive data-channel which, of course, occur on ports from the command channel? Association for use with snort flowbits to identify ftpsessionsand eliminate FPs on troublesome rules. . .
