We’ve been working on developing our own iptables firewall, login failure daemon and WHM front-end. The idea is to provide a complete, straight-forward, easy to configure and maintain, solution. There are, of course, other products available that can provide you with this functionality. However, in our experience over the years, we’ve found them lacking in some fundamental aspects. We’re trying to address those with our new development.It’s likely to stay in beta-testing for some time (once we have that available) to ensure that it is robust as possible.For now, the product will be Linux only (possible RH and derivatives only) and we are as yet undecided on the license we will distribute the product under and how that distribution is done. It will also be exclusively for cPanel servers, certainly initially.We’re hoping to have this working on VPS servers, but it depends a lot on your VPS provider and their willingness/ability to provide the correct iptables modules in their kernels.More details will follow in due course, including a call for brave beta-testers ;)Visit the products page on our site here.
There’s a bug in the MailScanner code where if you have it configued to scan HTML email for dangerous content it actually strips out link text and images. To correct this, you can either:
- wait until the next release from MailScanner
- install the latest beta release by modifying msintall.pl to use the URL to the distribution on the www.mailscanner.info site
- apply the following patch…
You need to replace the Message.pm file in /usr/mailscanner/lib/MailScanner/ :

I have added a new page to our site to explain some of the processes that we go through when Searching for Spammers on a server. The hope is that this will help readers to understand where spam comes from and, using that knowledge, how to backtrack through the server logs to find the entry point on your server.It isn’t meant to be a comprehensive guide on the subject, but I hope it gives you a starting point. Hopefully it also illustrates some the work we do as part of our Anti-Spammer/Exploit Service.
Just had a problem on a clients server which took a while to track down.Symptoms: If you rebuild apache/php and find that httpd appears to hang without spawning any children and nothing in the error log, this could be the problem. Using an strace on httpd -X shows the binary hanging on apache module loads.I finally tracked this down to Zend Optimizer v3.0.0 which is available in the current EDGE/CURRENT releases of cPanel ( 10.8.2-EDGE_41) in /scripts/installzendopt. Trick is to edit the script and set:
Then rerun the script and restart httpd. Hopefully this will help anyone who finds themselves with the same issue.
