Hello,

we have the following plan:
In the next year we would migrate our CentOS 4.6 Server to a new CentOS 5 Server.
We would install asl2.0. Have you got a test version from Asl 2.0?
Can we integrade Asl2.0 on our CentOS 4.6 Server too without any Problems?
Our Server have the following configuration:
Plesk 8.1.1
4PSA Integrator
4PSA Clean Server
Rkhunter
RFXNetworks Tools:APF,LSM,BFD,NSIV,LES
Modsecurity 1.9.5
We would upgrade to Mysql and Php 5

What are the steps to be taken?

Kind regards

Yep, it works with centos 4 just fine (this server runs C4). You would need to remove source installs of rkhunter or mod_security prior to installing ASL. If they were installed as RPM's you dont need to do anything special.

There is no demo or test version available at this time, I think we'll start working on that next quarter.

The old modsecurtity 1.9.x rules from gotroot are very memory intensiv (out of memory). We must deaktivate every blacklist rules on our Server (2 GB Memory).
Is 2Gb Memory enough for all rules from modsecurity 2.5.x.

Kind regards

I run probably 99% of the ASL 2.0 rules on 2GB of memory without problems (although dosevasive proved troublesome).

Yup 1.9 and especially 2.0 couldn't handle a lot of rules. Actually you're in luck using 1.9, 2.0 would have been much much worse.

2.5.x can handle a lot more with the new pmFile tokens, so yes 2G is fine. Side note, in case you didn't put 2 and 2 together, we are gotroot.com

thank you for the fast answers. After our vacation we upgrade our php und mysql version from 4 to 5 and then we would integrate ASL2.0.
I have read that plesk 8.1.1 have troubles with php5 and mysql 5.
What are the cost for a professionel php5 and mysql5 update and plesk troubleshooting from you?
You can send me a privat message.

Thank you in advance
Kind regards

Just mysql 5, PSA 8.3+ support it. You wont have any problems with PHP 5 on an 8.1
