DDOS Protection x_connlimit issue
February 2, 2014 Abidoon Leave a comment
Note to self:
The Linode kernels for CentOS 6 have built in support for xt_connlimit so it will not load a module. The kernel is monolithic.
Checking via the csf test script will always show:
Testing xt_connlimit...FAILED [Error: iptables: Protocol wrong type for socket.] - Required for CONNLIMIT feature
RESULT: csf will function on this server but some features will not work due to some missing iptables modules 
This is because it assumes that this will be a module.
