Snort GUI slows down after a while - 2.6.0.2.1 and previous version
-
Great sullrich, thanks for adding the checkboxes!
I'm afraid i haven't made myself clear abot the issue. So i'll make a new attempt
1. Installed the latest snort about 8-9 hours ago and rebooted
2. After reboot went to Snort_Snort Blocked. 3 blocked IP's appeared at once
3. 15 minutes later i clicked on the tab Snort Blocked to update the list - 20 IP's on the list. Update speed not an issue. 20 is about max this FW ever has. Left the PC as is
4. Caught some zzz's
5. 8 hours later clicked on the tab Snort Blocked to update the list
6. Snort GUI hangs
7. Clicked on Snort Settings with the intention to "unselect" the show descriptions (show links already unselected). Nothing happens, the tab doesn't show up.
8. The result of the above is that 2 instances of php are running and nothing happens in the GUIlast pid: 34470; load averages: 3.50, 3.32, 3.20 up 0+09:06:24 08:59:01

Hoping that will work, which is ok by me. Just wanted to let you know.

I cannot reproduce this.
Please provide a ps awwux | grep php output during this time.

I've un-checked all new features. Had to hard-reboot FW some hours ago because i could'nt connect to the console anymore.
This took about 5-10 seconds earlier.

You are running out of ram. Insert more ram?
-
Snort has some performance settings. Did you try low mem already?

So RAM is the culprit. Didn't understand that.
Dont' know much about ..nix i'm afraid.
Just looked at System Overview that shows about 62% Memory usage.Yes, i'm running Performance: lowmem.
Have no more RAM i'm afraid. MB only has 2 slots. Already equipped with 2x128MB and i don't have any 256MB's.
I'll disable some snort rules and maybe uninstall Squid.Thanks for your help and sorry to have taken up your time with such an stupid issue! My bad.
I promise i'll learn all about FreeBSD memory management and status after a short nights sleep, which starts right now (1:30 am) … -
maybe remove just one of the "memoryhogs". squid and snort both can take some fair amount of ram.

I am having the same issue with PHP using ~100% of CPU cycles while having lots of blocked IP addresses. I am running a P3 533MHz w/ 512MB of RAM. When clicking the snort link within the GUI, CPU usage goes to 100% and stays until the page is loaded.

If it returns a result after some time that's normal. I tries to use the available cpu power to run the commands to build the pages as fast as it can. Isn't it normal that cpu goes up when the cpu is working? ::) At least it is normal when it returns a result after some time (depending on your systempower sooner or later). It's not normal if the process keeps at 100% cpu without returning anything after some time but it doesn't sound like you have that kind of issue, right?
-
It is normal. If you dont want it to associate the blocked alert text with the ip address then disable this feature in the settings page.
-
Woops. This just happened to me! I've hopefully fixed the problem.
Sorry about this!!
