Hi,

We have 2 Red Hat 5.5 web servers and are having problems with DOS flood / SYN attacks which stops the coldfusion service responding.

Can anyone help with a Mod which will help?

Thanks,

Daniel.

Apache has mod_evasive and mod_security modules that can help with DoS (and other) attacks.

Also you can look at limit module for iptables firewall.
