Default newbie, 2.2.0a, no packets out of snort-inline

Hello!

Sorry for posting here, but I don't receive any mail from sf.net mail
and can't subscribe to inline list... :-(


I'm starting snort_inline with default config (i.e. from tar.gz), then
I want to check ftp:


iptables -A INPUT -p tcp --dport 21 -j QUEUE

I see that snort_inline get packets:

Received error message 2

But there is no ftp

OK, another try:

iptables -A OUTPUT -p tcp --sport 21 -j QUEUE

Received error message 2

No difference.


I tried this on Suse 8.1/x86 with kernel 2.4 and Mandrake 9.2/AMD64
with kernel 2.6- the same result.

Any ideas?
