I just edited the code, because I was too lazy to find the request. The same is there though.

This doesn't seem to be effective enough to block a DDOS. In fact attacking IPs spam the access logs and don't seem to be blocked lsws's firewall.

I think the issue is I am trying to grab the access my site by the domain (root) - that goes through, but everything else doesn't. For some reason that rule isn't applying to /. 77.9.186.5 - - [22/Jun/2012:19:20:55 +0200] "GET / HTTP/1.1" 200 25992 "-" "-" 77.9.186.5 - - [22/Jun/2012:19:20:55...

I'm trying to block users who don't have a user agent: SecFilterSelective HEADER_USER_AGENT "^$" SecFilterSelective HTTP_USER_AGENT "^$" Neither work and yes I am using vhosts, no Apache. Any suggestions?

What does that mean exactly? I have these in my logs and am unsure what is the exact reason. I went to check the log after getting a lag spike and saw that. [STDERR] die 4 true [STDERR] die 4 false

IWT, it is missing some sort of caching mechanism.

It turns out that the issue with load has to do with a plugin and the lack of cache for queries. Whenever someone attacks vbulletin's index.php, I see this spammed about 200 times: | 20126 | forumvb4 | localhost | forumvb4 | Query | 2 | Sending data | SELECT forum.forumid...

I changed that to -1 and changed the compression. I thought the small/medium file cache is memory based (that is the reason for me setting it so high). The pages seem to be loading quicker, however the server is no longer optimized for DDOS attacks which seem to have started out of the blue. I...

I am using memcache instead of XCache. My previous tests with XCache didn't show much of a performance boost compared tests with memcache. I don't know which is quicker tbh, everyone has a different opinion. I think the swap is being used with litespeed. I enabled the caching of pages for...

With 24 threads I should theoretically be permitted to have a load of 24. That is also what is bugging me, the load is only 6 right now, yet the site loads extremely slow. It isn't even utilizing the full server. top - 22:47:20 up 176 days, 21:02, 2 users, load average: 6.00, 6.61, 6.95...

Ever since I've installed LiteSpeed I've been trying to optimize it. I've gotten to a point where I think found the problem: Is the number of requests vs the number being processed off or something? Shouldn't more requests be processed, what could be the reason for so few requests...

Do my configurations look correct? I've been having a couple large lag spikes coupled with timeouts/500 errors. I have a 2 core, 24 thread server with 32 gigs of ram, there shouldn't be any problems with system resources as I host 3-4 sites off the server, 1 large one and several small ones...
