Hi all,
this thread is to add working REGEX that we can share with the community. To add them to this sticky, you should have the regex working in your server, this thread is not intended to solve any issues related with no working regex, the intention is to give users of CSF REGEXs that could make CSF with more security options.
If you want to collaborate, please add your rule to this thread...
If you have one particular IP address that is either dropped or accepted through the firewall that you think should not be, then you can use the new WATCH_MODE in csf.
Before enabling this option and using the CLI command to watch an IP address, check whether it is explicitly listed first using:
csf --grep 11.22.33.44
Where 11.22.33.44 is the IP address you're tracking. If that comes back...
If you get iptables errors when trying to start csf on a VPS then you most likely have missing iptables modules for your VPS.
If your hosting provider wants to know how to configure iptables correctly on a VPS server, then you should point them to this Parallels FAQ and have them follow it (plus to add ip_conntrack_ftp to the list of required modules):
Issue: Granting access to specific Ports by selective IP's and CIDR range to Remote Machine CentOS-7-x64 does not works, as no access to that specific IP's granted?
Hiya,
I'm trying to Grant Access to specific ports on my Remote Server CentOS-7-x64 by specific IP and CIDR range but it's not functioning. I added lines to:...
I don't know if this is a CSF bug or something else so I post it here.
In Centos 7, it was enough to put these lines in the csf.pignore file:
exe:/usr/bin/spamc
exe:/usr/bin/spamd
cmd:spamd child
no problems with perl mails about spamd and spamd child anymore.
Since Centos 8 this is change, no clue as to why.
On is about a suspicious process, the other one about excessive resource usage....
hello,
i have a server in cloud and i want access only from my ip
so i add in csf.allow my ip
and in csf.conf i set
TCP_IN =
UDP_IN =
same for ipv6
but when i reboot server, is offline...
i can't access in ssh but if i access with console (on provider panel) and try to ping 8.8.8.8
network is unreachable
of course server have a public ip, but is not static settings but keep ip from DHCP...
It is possible to edit the file that sends the email to include other parameters such as:
Client IP
Page title
Because then I will know which client is doing something wrong in the system.
Original email I receive:

I used to have this enabled and had made the necessary changes to the exim configuration to make it work. I have now disabled it in both CSF and exim configuration, and restarted both firewall and lfd, and exim. I have ports 465, 587 and 25 enabled and open for SMTP auth.
But I can't connect to the server from Apple Mail for SMTP. Apple reports: Unable to verify account name or password.
I would like to know if it is possible to use different users without having whm installed on my server, on this server I have a different application but I want to create users that can only unblock IP's.
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 ?
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 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...
