Hello,

I see everyday similar action. How can I block with CSF firewall ? For example more than 50 packet per IP blocked. CT_LIMIT not help this problem.

Hi ,

I just installed CSF on an Asterisk box.
Is there any setup I could use in order to block IP addresses that failed to login on SIP / port 5060 with the help of CSF ?

Thanks !

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.

The postfix maillog (/var/log/maillog) is showing a lot of SASL authentication failures like this:

May 5 09:21:38 myserver postfix/smtps/smtpd : connect from unknown
May 5 09:21:39 myserver...

I've been receiving this message for over 1 month - any ideas? Is it a configserver.com issue?

I obviously don't want to post my server IP here.

Thanks,

Rob

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,

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:

root 2398 0.0 0.0 124500 1620 ? Ss Apr27 0:01 /usr/sbin/crond -n
root 13451 0.0 0.0 222996 3648 ? S 00:00 0:00 \_ /usr/sbin/CROND -n

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...

I have the LF_PERMBLOCK_ALERT set to OFF and have saved and reloaded CSF. Still, even after turning it off I am getting dozens of PERMBLOCK alerts in my inbox every day like the one pasted below. Am I missing some other setting that I have to change to stop CSF from sending me all of these?
