I am trying to install owncloud on a Ubuntu Servers as a docker container.
I am following this documentation.

If I disable CSF all works, but if it's enabled, it doesn't and I see these messages in the logs.

Now, as I see CSF is blocking the traffic between the docker containers or just the port 8080? It's not clear for me.

Any tips?

I setup CSF with ansible using the following config:...

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?

Hi there

The default refresh rate appears to be 5 seconds.

Is there a config setting somewhere to change this to e.g. 15 seconds?

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.

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 all,

I am getting a lot of e-mails about suspicions process running. I did find many threads about it and all pretty much talk about how to silience those.
I want to fix (if possible) the underlying problem.

Those warnings are generally only specify user and PHP executable.

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?

Hello,

I'm using LF_DISTSMTP to help to detect compromised email accounts.

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

Is it possible to LF_DISTSMTP ignore this specifics accounts? How can I do that?

Thank you

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,
If I have a user getting blocked with an ip address say 203.57.138.20 (Not real IP address)
I now want to find in the logs why he was blocked. This IP address is currently unblocked so looking at csf.deny does not help

Kind Regards

Steve

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.
