I've got an issue with my CSF firewall installation on my VPS.
Here's the csftest reply:
Testing ipt_recent...FAILED [Error: iptables: No chain/target/match by that name.] - Required for PORTFLOOD and PORTKNOCKING features
Testing xt_connlimit...FAILED [Error: iptables: No chain/target/match by that name.] - Required for CONNLIMIT feature
RESULT: csf will function on this server but some features will not work due to some missing iptables modules 
Now the strangest part:
root@server04:/etc/csf# csf -s
No errors, but it is not running... nothing is showing up @ ps aux.
Does anyone have a clue?
