Hi guys,

I'm running Postfix on a generic Centos 8 server and I'm trying to lock it down with CSF. I've done a fresh install, reviewed the conf, set testing = 0 and restarted the service.

Hello All,

I got all of the settings double checked to setup the CSF Cluster, I have all nodes sharing both send and receive and the firewalls are open on each, so when I cping test it comes back with pong, so communications is happening.

My test was to add an ip on a deny list and then check if that IP is on the deny list on all the servers in the cluster.
I added a comment as well, so I was...

Hi,

Currently the ModSecurity Log page doesn't update automatically, it would be nice to have a way to auto refresh the page just like the Watch Logs feature within ConfigServer Security & Firewall.

The next improvement that would make a huge difference is simply adding a column for Status to tell us if it's a 200, 403... etc. The same way how cPanel's Mod Security Hits list has the column...

Hi,

I tried first installing CSF from the guideline provided on your website: but this created a huge problem for us. Our server was filled up with 60k+ processes like this:

hello -

i am having trouble being able to UNblock by a specific port, in this case, 3306.

in my csf.allow file, when i have just the following:

123.123.123.123

i can certainly access port 3306 as expected.

HOWEVER when i only have the following: ( i included ALL i could think of just to see if that helped)

tcp|in|d=3306|s=123.123.123.123
tcp|out|d=3306|s=123.123.123.123...

Hello,

Hello
As a server admin I would find it usefull if it was possible to interact with the MailScanner interface via an API, or via CLI commands, so some things could be scripted or integrated with existing custum user interfaces.
Thanks
