CSF needs iptables to run. Please reinstall iptables then it should work. You might have to re-run the installer (but you shouldn't have to).

Now It's Working. Thank's

Hello,

I installed on my vps, but it does not work with Proftpd. Do not block!

How do I block Proftpd?

Change the file /etc/csf/csf.conf and find

Code: Select all

FTPD_LOG = "/var/log/vsftpd.log"

and change to where proftpd log is

Code: Select all

FTPD_LOG = "/path/to/proftpd.log"

Thank you.
Worked perfectly on my Centos 6.9 server. However on my Centos 7 server it did not work, it is not blocking proftpd.

Centos 6.9 OK!
Centos 7 Does not work

What could be happening?

I'm not 100% sure. This is a CSF issue.

This post should help you: viewtopic.php?f=20&t=10209&start=80#p57236
but you would need to modify it for proftpd to match the login fails.

Try this instead:

Edit file /etc/csf/regex.custom.pm

Add the following BEFORE return 0;

Code: Select all

if (($lgfile eq $config{FTPD_LOG}) and ($line =~ /FAIL LOGIN: Client \"(\S+)\"/)) { return ("Failed FTP login from",$1,"vsftpd_ss88","5","20,21","1"); }

So your file will look something like this:

Code: Select all

Of sorry, that was for vsftpd. Can you show me the logs of Proftpd which show the login errors and I can make a regular expression to match the ip address.
