Snort inilization failure
-
Question is, why?
No idea. This is now a SNORT issue and this should be asked on their lists.
-
I think the latest version of SNORT (2.6.1.1) fixes this issue
-
Not sure if this fixes our issue.
This is the issue solved in 2.6.1.1: "Fix problem with snort using high CPU and reprocessing the same rebuilt packets at session end or ACK in middle of packet when there are gaps in the packet sequence."
-
certainly seems to :)
Running in sparsebands now, only been up for ~5 minutes, but that's ~3 more than I've managed before
-
I updated to the 2.6.1.1 versions and now I cant even get Snort to boot up on any performance setting. I am getting brand new errors now:
Nov 24 14:53:39 snort2c[1571]: unable to open alertfile - exit
Nov 24 14:53:39 snort2c[1571]: unable to open alertfile - exit

Oh bugger. I'll check it out a bit later tonite.
-
Thanks Scott.
-
Didn't do that for me, BUT it also didn't trigger any alerts
-
Try running a port scan from http://www.grc.com. You should see it appear in alert as a ping.
-
I'm pretty much screwed with the same alert after I upgraded SNORT. Now the service will not start and stay running.
-
Scott, I see where you reverted snort back to the 2.6.0.2.5. I reverted back to that version and I'm still getting the same error. The trouble must be in the latest snapshot.

I know, and it doesn't.
I've reverted back to the older version and it still doesn't raise any alerts at all ???
-
What snapshot are you running? I'm thinking it has something to do with that since I too reverted back to the older version of snort.
-
Version 1.01

Well, it boiled down to me just re-installing pfSense(1.01) and re-installing SNORT. It started fine. I kept getting could not open alert file…..no matter what I did.......but now (keeping my fingers crossed) everything looks good.
-
I think I'd rather do without snort than re-install from scratch
-
Backup your configuration, reinstall, restore configuration.
It takes about 6 minutes on a 800 mhz machine.
-
If you backup your configuration to a media (floppy/USB stick) to /conf/config.xml your users will only see 2 short downtimes while the pfSense is rebooting. The livecd will come up with your old config and the system will be usable while you are installing it to the hdd ;)
-
Thanks Hoba, I'll give that a try later.
Oh, Fyi everyone, I've taken on a little issue I saw with snort. I've been wanting an easy way to enable, disable, and edit snort rules. So I've started workin on this. It's not done yet, but the screenshot below shows the progress I've made in the last day.
Right now I've got it to list the rules in a cleaner format, but they are not yet editable.
Enjoy.
