Re: Blocked IP still comes back

Does anyone from CSF participate in this forum.
I regularly see lots of questions with little or no credible answers.

Re: Custom REGEX rules for CSF.

Using Host Access Control in WHM, its possible to restrict Cpanel login to specific IP or range of IP's. However, any unauthorised log in attempts will generate the following warning: "Dropping connection from xxx.xxx.xxx.xxx because of tcp_wrappers at cpsrvd.pl line ####" There are no res...

Re: really could do with some help on a custom filter

I've scoured the custom regex thread and it doesn't matter how many times i read it, it makes absolutely no logical sense to me.
I think writing my own regex is out of the question.

really could do with some help on a custom filter

Returning to work today, I see multip[le attempts over a number of days of someone trying to log in to cpanel.

Dropping connection from xxx.xxx.xxx.xxx because of tcp_wrappers at cpsrvd.pl line 3622

Is anyone able to help me write a custom rule which will block the offending IP.

Re: CSF blocking Google Image Proxy Server

Try clearing out the blocked IP's and stat with a fresh blocklist.
This may help identify google.

Re: Best practices hardening a Cpanel / WHM Setup?

Whitelist your IP in CSF. Using host access control (cpanel) allow ssh access to your IP or IP's, then deny SSH to all. Then change the port number to something else. https://forums.cpanel.net/threads/change-ssh-port-via-whm.108197/ In csf, configure ssh logins to something really low like 3 strikes...

Re: can anyone suggest a custom SA rule

After a number of experiments and waiting for these emails to arrive, I may have figured it out.
Just in case anyone else needs this, this is what I came up with.

header FROM_YOURRULENAME ALL =~ /mydomain\.co\.uk@/i
score FROM_YOURRULENAME 0.1

Giving it a very low score for testing purposes.
