Re: Snort Upgrade

[Matt Watchinski <mwatchinski () sourcefire com>]

You'll need to add something like the following to your snort.conf for
2.8.4 and the new dcerpcv2

preprocessor dcerpc2: memcap 102400, events [smb, co, cl]
preprocessor dcerpc2_server: default, policy WinXP, \
detect [smb [139,445], tcp 135, udp 135, rpc-over-http-server 593], \
autodetect [tcp 1025:, udp 1025:, rpc-over-http-server 1025:], \
smb_max_chain 3

and remove the old preprocessor dcerpc statements.

Cheers,
-matt
