I don't know if this could be the issue or not. For some reason I am still not able to start the service. The only way to actually show that it's working is to completely uninstall snort and then install it again. I'm beginning to think this program is really buggy on pfsense virtual machine.
something must be wrong in your installation... snort is not that buggy... yes, it has bugs but nothing like basic installation and operation problems you seem to be reporting... the environment that i work in is a lot more "closed" than pfsense seems to be... there is something deeper at work here...

Once it's running and listening on the interface, if it seems packets/traffic that matches the rules it alerts/passes/drops/etc.. When you startup snort, near the end of the messages that it spits out it should tell you what interface it's listening on: "Jan 28 20:38:53 iiaabqst001 snort[23678]: Acquiring network traffic from "eth1"." Look for that, that's the port snort is listening on to process packets. Then go back to TCP dump and see if you are seeing all packets for all the traffic, or just certain packets to that address.

I don't really know how to plug snort into that equation to see if snort "see's" traffic or not. -----Original Message----- From: Jeremy Hoel [mailto:jthoel () gmail com] Sent: Monday, January 28, 2013 11:58 AM To: snort-users () lists sourceforge net Subject: Re: [Snort-users] Snort and Proxmox Ok, so snort is up, and you say its seeing all packets, but the rules aren't firing? What is your snort output set as? Hve you tried using syslog or portfast just so you can see the output vs it going to a binary file? Also, please reply to the list, so that others might be able to chime in or help out.

If it's set to start, but then isn't running after boot, it probably failed for some reason. Snort is pretty good about telling you why it stopped.

I come in this morning to start working and start up the VM's and I'm showing the service not even running in PFsense. I restart everything even reinstall the snort package. Even on boot up it shows snort service started......but looking at top and also via the web gui it actually isn't running.....Any ideas? -----Original Message----- From: Jeremy Hoel [mailto:jthoel () gmail com] Sent: Monday, January 28, 2013 11:13 AM To: Josh Bitto Cc: snort-users () lists sourceforge net Subject: Re: [Snort-users] Snort and Proxmox You should start with running TCPdump on the listening interface on the snort box to make sure it's seeing the packets you expect it to see.

We've decided to use snort on our network and in doing so I've setup a small test lab away from the actual network to see how this IDS works. So here's the problem.....I can't get snort to show any logs. I want to be able to see if it's actually working or not. I set up a stand-alone server with proxmox on it. Created 2 VM's One is Pfsense The other is just a xp machine. In proxmox interface.conf looks like this. Config looks like this: Auto lo Iface lo inet loopback Auto VMbr0 Iface vmbr0 inet static Address 192.168.3.15 Netmask 255.255.252.0 Gateway 192.168.1.1 Bridge_ports eth0 Bridge_stp off Bridge_fd 0 Auto vmbr1 Iface vmbr1 inet manual Bridge_ports eth1 Bridge_stp off Bridge_fd 0 I did everything to spec in pfsense....its pretty straight forward. 1. Setup the interface on pfsense to match in proxmox 2. Downloaded the snort package 3. Obtained a oinkmaster code 4. Created the WAN interface in snort. 5. Checked ALL the rules to activate them. 6. Even restarted both pfsense and the snort service. I just for some reason can't get the darn thing to log events....as a test. I activated teamviewer rules and tried to block an event and couldn't get it to do that. So my thinking is....Its somewhere at the interface. I just don't know what I need to do. Any help would be greatful!
