You will have to have a separate snort process running for each interface you want to listen on. Like so: /usr/sbin/snort -A full -d -D -i eth0 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort/eth0 /usr/sbin/snort -A full -d -D -i eth1 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort/eth1 /usr/sbin/snort -A full -d -D -i eth2 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort/eth2 /usr/sbin/snort -A full -d -D -i eth3 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort/eth3 /usr/sbin/snort -A full -d -D -i eth4 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort/eth4 Now, the script that comes with the Snort rpms will spawn a separate snort for each interface you specify in the /etc/sysconfig/snort configuration file. I don't know if the source distribution comes with such a script, but it probably does. Hope that helps, Chris Vaughan -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net]On Behalf Of sEc nErD Sent: Tuesday, February 08, 2005 10:21 AM To: Leon Ward Cc: snort-users () lists sourceforge net Subject: Re: [Snort-users] Snort Install for monitoring 5 interfaces? Hi LEon, Thanks for your reply.Ok right now i have set it up in a test lab enviornment and its listening on one interface.I am still not clear what i would have to do for listening on 5 different interfaces??? i have the acid up and running just not contacting the mysql database but tht i will struggle and work around,but i do need to understand the part for 5 interfaces...could you please detail on thzt thanks Leon Ward <leon () countersnipe com> wrote: Hi Sorry if this is a bit quick, but in a rush. snort needs to connect to a single interface on start-up, this leaves you with two options. A) Have multiple snort instances running bound to each interface. - This will allow you to customise the configuration for each, I assume you will want to protect different things on the DMZ compared to the internal_net B) Team the interfaces together so you can attach snort to interface bond0 Take a look at the following link, it may answer a few questions (I'm a debian man myself) http://www.ms.washington.edu/Docs/Linux/rhel-rg-en-3/s1-networkscripts-interfaces.html#S2-NETWORKSCRIPTS-INTERFACES-CHAN Hope the above helps. -Leon On Sun 2005-02-06 at 06:04 -0800, sEc nErD wrote:
