I have PT_USERMEM set to zero but I still get the emails. How is this possible? So much so that the email address that it sends too is now blocked by outlook. So now I just get the email failed messages.

Yes I know I should either stop my scripts from doing it or buy another 100 CPUs but I just want to stop the crazy amount of emails I get.

Hello,

I hope everyone is well.

I have a need to block countries, but allow dns querries into the server from everywhere, including those countries I've blocked.

What is the simplest solution with CSF for this?

Thanks in advance for any help.

no list of option. It only shows:

# csf -h
csf: v14.10 (cPanel)

That's normal?.

Btw, Is there some way to reinstall withtout loosing the configuration?

Hi,

My client is getting ban from CSF every time when he changes the ip. His ip is dynamic, I'm trying to whitelist him but once the ip is changing he is getting ban.

He is using Jazler to upload from radio the song titles in website using ftp connection.

How we can fix this issue to allow his ftp connection by hostname or by domain?

Thank you

Is there a way to blacklist an IP based on the repeated failures like the following logs?

I get these from journalctl not sure if they are also logged somewhere else.

Is it possible to do advance filtering using the command line?

It seems like the only possible way is to write the directly to the rule file?

It works fine but I have a few email accounts for sending reports that have distributed logins.

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 !
