-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1I think Snort's primary packet struct has to smoothly incorporate a notion of encapsulation in order to effectively handle IPv6 and all the variations of tunneling that can occur with IPv4/v6 networks. I've got some prototypes of that sort of thing worked up but even once the decoder supports it, all the code that references IP addresses (and uses them for hash tables, etc) has to be updated to account for v6 addresses.
This is definitely on the TODO list, sorry it's taking so long! -Marty On Dec 15, 2005, at 4:14 AM, Chas Tomlin wrote:
If you'd like to try out a version of snort with IPv6 support give thismodified version a go; http://www.ecs.soton.ac.uk/~cet/snort/snort-2.3.3-IPv6b4.tar.gzIt has been modified by Ken Renard whom you should contact with any bugsetc. It would be really nice if the official snort version had IPv6 support sometime soon? What d'ya think Marty??? Thanks Chas Tomlin-----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users- admin () lists sourceforge net] On Behalf Of Dirk Geschke Sent: 13 December 2005 19:11 To: Caceres; snort-users () lists sourceforge net Subject: Re: [Snort-users] Snort doubt Hi Caceres,What the Snort's state of art about IPv6 support? Can Snort identify IPv6 attacks attempts in the network?not yet... A long time ago Marty released a beta (or alpha) version of snort supporting IPv6. But it was more a framework than an usable system. The actual version of snort is only IPv4 capable, IPv6 packets are only counted.I searched in the Snort.org page and I discovered that IPv6 appearsinSnortStatic's. I find to, that exists at least 3 rules for IPv6 (ICMP IPV6I-Am-Here, ICMP IPV6 I-Am-Here undefined code, ICMP IPV6Where-Are-You,ICMPIPV6 Where-Are-You undefined code) intrusion detection.This are IPv4 ICMP messages regarding to an original IPv6 packet. So this works for snort... Best regards Dirk -------------------------------------------------------This SF.net email is sponsored by: Splunk Inc. Do you grep through logfiles for problems? Stop!
