RE: EXPERIMENTAL IPv6 decoder available in Snort

"This decoder is implemented to test Snort's capability to analyze IPv6 and IPv6 tunneled over IPv4."

Don't you mean IPv4 tunneled over IPv6? (as in IPv4 traffic being sent inside an IPv6 tunnel) I thought that was Lance's issue. I might be mistaken here. In any case, thanks Marty. We love you ;)

Cheers, merry Christmas and happy new year.

Onderwerp: EXPERIMENTAL IPv6 decoder available in Snort

Hi everyone,

     Following up Lance's message regarding the usage of IPv6 tunneling on a
honeynet, I'd like to announce the availability of an *experimental* version
of Snort with an IPv6 decoder. This decoder is implemented to test Snort's
capability to analyze IPv6 and IPv6 tunneled over IPv4. Currently it consists of a decoder and printing module only, so if you want to test it
and see the v6 output, just run 'snort -dv'.

If people would like to test the code out and see if it's working properly,
it can be downloaded and tested at:

This code currently doesn't have any components integrated into the detection engine, so you can't tell Snort to look at IPv6 addresses or header fields using the rules language yet. It is capable of looking for
standard embedded protocol headers and payloads in IPv6 tunneled over IPv4.

If people would like to test this code out, I'm primarily interested in seeing if the code is stable and capable of decoding all v6 traffic without
any memory leaks or crashes. Unfortunately, my ability to generate v6 traffic for testing purposes is extremely limited right now, so I'm depending on people with access to the right kind of networks to help out!

Once I'm happy with the decoder, I'll integrate IPv6 support into the detection engine!
