Yes, that seems to have done it!

One thing though; I had to use the lowercase i, i.e.

snort -D -i eth0 -i eth1 -c /etc/snort/snort.conf

Thanks!

Are you sniffing with the correct nic ?  -I eth1

Hi all,

Only just start with Snort, and I'm a little puzzled as to why I'm not
seeing any alerts...

I'm running all Linux, and have this setup:

Box1 -- Box2 -- Box3

Box2 is running iptables and snort, and has 2 NICs. Everything works
cool, apart from I don't see any Snort alerts.


I think the two most relevant parts from my snort.conf are:

1.) Sending the alerts to the syslog
output alert_syslog: LOG_AUTH LOG_ALERT

2.) My test rules:
include $RULE_PATH/test.rules

test.rules contains:

alert tcp any any -> any any (msg:"TCP traffic";)

Snort is started with -D -c /etc/snort/snort.conf and shows up in the
process list.

In theory, any tcp traffic should generate an alert in the syslog, yes?

So I FTP from Box1 to Box3 and connect OK, which should generate an
alert, yes? Unfortunately, I get nothing.

Any help much appreciated?
