I thought I would add my settings here: CT_LIMIT = 300 (changed to 500) SYNFLOOD = 0 LF_BIND = 0 PORTFLOOD = (empty) (Virtuozzo VPS) CONNLIMIT = (empty) (Virtuozzo VPS) DNS_STRICT = 0 DNS_STRICT_NS = 0 CC_* = All (empty) except CC_LOOKUPS = 1 TCP_IN/TCP_OUT/UDP_IN/UDP_OUT = '53' in all settings Chee...

I am not a networking expert, I hired you folks to install the CSF firewall on my server, its been running for years well, and thought it prudent to ask for help here, as this is a very new and seemingly CSF related issue. My datacentre runs APF not CSF, I much prefer CSF and so installed it, but fi...

OK - this looks like a potentially MASSIVE problem for CSF. Chirpy, ----IF my hunch is right CSF, is going to be the cause of millions of undelivered emails to corporations using Microsofts FOFO services, because of the distributed and aggressive nature of the FOFO email validation checks. I would b...

If you add the IP address of your network (whatismyip.com) to CSF ignore, does the problem go away for your computer?

I have a server that CSF is intermittently stopping dns calls being reached and don't know why.. They may be related.

Tracert has the same issues, sometimes gets through, sometimes takes a few attempts. How do I get this looked at by a professional ? It started only 3 or so weeks ago and is causing companies to move their DNS services away from me... Its definitely CSF that is causing the timeouts, I am not sure ho...

Also, this is causing me huge problems with companies that need to ping my DNS to check email domains. Many emails are being rejected due to this bug/issue.

Is there any official support ? I had all my CSF firewalls installed by chirpy et al.

Hi Folks, I have a WHM server running CSF that has an intermittent DNS problem. Here are the symptoms. .............. ping dns1.xxxxxx.com -t Request timed out. Request timed out. Request timed out.

Thanks for looking into this folks, I feel better now! I have literally found these dodgy scripts in my /tmp folder, but I assume that they are not able to ever be run? All of mine have been generated by a php file that does not exist.. Can you shed any light on how a hacker is uploading the tmp fil...

Just to let everyone know, it looks like the slowdown problem was related to memory, and therefore I exclude any of my previous thoughts as to why this was happening re exim etc.. The interesting thing is that my server was reporting 1.6G of Ram free (from 2G) when in actual fact the VPS (Virtuozzo)...

In looking through logs etc today with my tech support guy, we noticed a few things.. 1. The overload issues have only been happening for a couple of weeks. 2. A couple of weeks ago I turned on the setting "SpamAssassinTM: Reject mail with a spam score greater than 10 at SMTP time." in Exi...
