Subject: Re: [Snort-users] 1st Instance of Snort Fails When Starting 2nd


This shounds like a limitation of one promiscuous process per interface
under Linux:

Try this:

1.      Manually put interface1 into promiscouos mode:
        # ifconfig eth0 promisc
2.      Manually put interface2 into promisciouus mode:
        # ifconfig eth1 promisc
3.      Add -p option to snort instance one init script.
4.      Add -p option to snort instance two init script.
5.      Restart all snort instances

I now observe this after upgrading from 1.9.1 to 2.0.1:

This Redhat 7.3 box has 2 sniffering interfaces with 2 different 
snort.conf's. A "-T" start shows no sign of errors for both configs. 
The first instance of Snort starts fine, but after trying to start the

2nd, the 1st disappears. Any clues?

Thanks, G
