I have ConfigServer Security & Firewall installed on my WHM/cPanel server. It's great and really thwarts a lot of intrusion attempts as well as other security features.

Have one BIG problem however. For security I have SMTP_BLOCK enabled to stop spam out from malicious scripts (if any where ever installed). Under CSF configuration I have SMTP_ALLOWUSER set to the accounts that I always want to...

I upgraded to cP 11.38.0.16 on 6/14/13. Afterwards (on the same day) I updated all CSF scripts with: curl -s configserver.com/free/csupdate | perl as suggested in the log.

Last night (6/17/13) or early this morning MailScanner stopped running (which hasn't happened in a very long time). In going through the logs to investigate what caused it, I found these entries in...

What does this message in lfd.log mean? I see it on both nodes in a newly configured generic Linux server cluster. I don't see it on my cPanel server cluster, which also includes one generic Linux server. Is something misconfigured?

I've been trying to work out why cPanel backups (New and Legacy) are causing massive load spikes making my server unusable. So far, with the help of cPanel support, it's been narrowed down to lfd.

They installed a system snapshot script to monitor the services, I then reported at the moment the spikes were happening. They used this information to check which service has been causing the...

Hello,

I have CSF on a cPanel server, and two times within the past two weeks I've received an email from the cPanel Service Monitor saying that LFD had stopped and had been restarted. I checked /var/log/lfd.log and found this:

Hi

I want to move from fail 2 ban to csf and i use a regex to check var/log/freeswitch/debug.log for failed auth attempts

how would i translate that into a regex for csf?

\ sofia_reg.c:\d+ SIP auth failure \(REGISTER\) on sofia profile \' +\' for \ from ip
\ sofia_reg.c:\d+ SIP auth failure \(INVITE\) on sofia profile \' +\' for \ from ip

I am having trouble with my CSF and denying whole countries.
I am trying to block the country of Chia.
I have the following line in my csf.conf file.
CC_DENY = CN,RU,VN,NG,RO,UA,IN
I have restarted my csf after I made changes.

I am still getting IP's from China getting to my server.
I have checked my server logs and there are IP's that start with 175.44, which are from China.

Hi guys, apologies if this is in the wrong section. But I've ran out of options on what to do with this specific problem. I've done the research, and I can't seem figure out what it is. Other people keep getting the MLSD error on the FTP side. I can connect perfectly (probably because cPanel/Server recognizes im the admin IP (idk))

But the error they get is:

Response: 200 PORT command...

Most of the posts with this error are on shared hosting. I have a dedicated server with this error.
When I run the IP Tables test from csf I get:

Hi,

We are using csfpre.sh to add some nat rules to our iptables.

After a server reboot, I need to restart csf service again for those rules to be added.

Any pointer on how to solve this ?

Thanks

With our WHM VPS, we use a third party service for weekly backups. This process always triggers the following:

/usr/local/cpanel/3rdparty/perl/514/bin/perl

We receive a CSF alert for each and every account that gets backed up. Is it safe to ignore this Perl path in csf.pignore? If so, do I simply add a line for:

exe:/usr/local/cpanel/3rdparty/perl/514/bin/perl

thanks.

Hi i keep getting a few of these below could someone please let me know how to fix this.

Excessive resource usage: mailman

I recently moved the IP of one of our DNS servers to a new cpanel server after checking DNS was running correctly on the server. However since moving the IP and adding it to the new server we are getting lots of LFd temp blocks for servers connection to DNS (example below)

Port 53 is in the list of open UDP ports in CSF so i'm at a loss to understand what the problem is. Anyone got any ideas....

Hello,

Anyone else have this problem? My CSF/LFD keeps banning my IP (usually from PopPeeper accessing mail too often), I try adding myself to the allow list, but my IP changes daily, or every time my connection is reset.

Any thoughts or suggestions on what I could do to keep myself unbanned?

Thanks sincerely in advance,

Edward Tate.

If I do csf -x and attempt to upload a file then it works, if I enable CSF then the upload drops. I'm sure I've missed a setting somewhere and would appreciate a point in the right direction.

I've diabled ICMP as that was causing issues but apart from that I can't think of anything else in the settings. I've been using CSF for years now and never seen this problem but have checked everything I...

Hello everyone, I set up CSF on my server that I plan on using to host a large Minecraft Server on.

I'm not sure of the best settings to use because I don't want it to start banning innocent IP addresses but still prevent attacks.

The Server will be holding ~100-150 people constantly, I am not using cPanel or any other web admin tool.

If anyone can recommend anything please reply back thanks.
