Re: Problem with stream5

That's because you're completely missing the options to your stream5_global
preprocessor. The VRT's standard config has this line for that:

preprocessor stream5_global: max_tcp 8192, track_tcp yes, track_udp yes,
track_icmp no max_active_responses 2 min_response_seconds 5

If you actually fill that line out, it should work just fine.

Dears,

I'm with a problem about stream5 in initialization of snort.
Below follow the logs:

*Verifying Preprocessor Configurations!*
*Nov 18 15:22:43 badejo snort[22444]: WARNING: Stream5 TCP default policy
not specified in configuration*
*Nov 18 15:22:43 badejo snort[22444]: WARNING: Stream5 TCP misconfigured

Bellow follow my stream5 configuration:

Can somebody help me?

Thanks.
