Hi Jonathan,
is it possible to add mod_qos to CSF?

Do you mean the tos (Type of Service) option in iptables, or something else?

iptables -m tos -h

Hi Jonathan,
I am referring to the new apache option called "mod_QoS" (quality of service) it is kind of new. I have been working with it for a few days and I like it.

What it does is to check what IPs are iddle and discard them, I like it and could be a nice addition to CSF.

Regards,

Sergio

I don't really see how csf would have anything to do with it - what log lines are you thinking csf should scan to block IP addresses from?

Mod_qos checks for IPs that are doing nothing on the server, just wasting a connection slot, look at an example of few IPs on my server today, errors are in the apache error log:
The first list of blocked IPs looked very suspicious to me, this could be blocked automatically by CSF in my server:

Or this other blocks from IPs trying to laid in my server with nothing to do:

The IPs could be blocked just in case it is a denial of service in the form of a "SlowLoris" attack.

Sergio, how do you get your logs to display the country name after the ip?

Mine just says... [Wed Dec 18 09:46:49 2013] [error] [client 78.175.166.177] mod_qos(045): access denied, invalid request line: can't parse uri, c=78.175.166.177, id=UrFvCW1LpMgAAF8qHLUAAAKI

Hi Craigedmonds,
I haven't done anything to CSF, it already displays the country name if your server is using geolite as part of the CSF script.

Oh thats cool. How do I enable that in CSF.

I can see geolite blocking under Country Code Lists and Settings but not any way to make it display the country in the logs.
