This is not a suggestion however, it's a bug. Not working as should be = a bug.
I wanted to block an ip on my current server and on the cluster servers, so I use the command like this:
csf -cd 82.146.54.128
But the ip is only blocked on the remote server (cluster server) but not on the local server where I issued the command. However the manual says this:
So the ip should also be added to the csf.deny but this does not happen.-cd, --cdeny ip
Deny an IP in a Cluster and add to /etc/csf/csf.deny
CSF v.8.12 on an Directadmin server with Centos 6.x.
From the other cluster server, I tried to do a block of a complete range like 91.200.12.0/22 and it only said "send to cluster" but nothing even got send. So this does not even work at all with ranges.
This is all reproducable!
