Dear all:

I've been using csf at least 5 years, great product.

I have setup a new server and installed it as usual. But as soon I enabled it, all the network goes crazy, the network latency pikes high, making almost unusable :confused: , I thought I was having issues with the ISP, but I then disabled csf and everything back to normal, enabled it, and the network slow down inmediately.

OS:...

Hi.
I have been using CMM for a long time and I will like to have two options in there that could help us a lot:
1. Download a zip file with all the emails that a user has in all his/her folders.
2. Upload a zip file with all the emails that a user has to his/her folder.

The meaning of this is:
1. We can do a backup of the emails that the user has.
2. Then we can use the backup file to recreate...

Hi!

I think it would be amazing if we could have advanced port filtering for csf.ignore file. I prefer to use this sparingly if not at all since it ignores all activity from an IP, but all too often we get requests from customers that cannot figure out which email client is causing them LFD blocks and want us to add their IP to csf.ignore. I provide the warnings about making sure all devices on...

Last night the server using CWP Pro comming with CSF and LFD upgraded to the latest version.

One of our websites/shop running on that server started having issues on the checkout page.

Page load times of normal cached pages got a little extra delay in it.
The checkout page however gotten an extra delay of between 20-60 seconds......

Yes u read this right 20-60 seconds delay on page load

It has become standard to block bad API calls with a 400 status.
With MVP architecture so prominent on the web, it has become commonplace to build everything as an API (for AJAX to serve the front end of a website).

Our API endpoints, especially login endpoints, constantly get bombarded with SQL injection attempts. These requests fail with a 400 Bad Request status.

It would be extremely useful...

Hi all! :)

I just wanted to confirm whether wildcards are supported in csf.redirect or not. The documentation seems to suggest that they are, but I get this:

Error: csf: Invalid csf.redirect format , at line 3249

With this:

# /usr/local/csf/bin/csftest.pl
Testing ip_tables/iptable_filter...OK
Testing ipt_LOG...OK
Testing ipt_multiport/xt_multiport...OK
Testing ipt_REJECT...OK

I added several repeat offender ASN's to CC_DENY. Was really excited about this because it could make my life a lot easier.

However, I was dismayed to see IP's from within those ASN's still hitting Apache. The field is setup like this:

CC_DENY = AS12345, AS23456, AS34567

Is this the proper format? I added 20 ASN's, are there any settings to adjust to allow so many? Perhaps DENY_IP_LIMIT? I'm...

Hi all!
We have these settings in place in CSF configuration file:

LF_DISTSMTP = 5
LF_DISTSMTP_UNIQ = 3
LF_DISTSMTP_PERM = 1
LF_DISTSMTP_ALERT = On
LF_DIST_INTERVAL = 300

And some DISTSMTP triggers have been intercepted because of some customer of ours having used Gmail for sending mail messages via our server's MTA.

So we received some mail warings (subj: distributed SMTP Logins on account...

Is there a way to skip the Apache status check in LFD altogether?

I tried setting: PT_APACHESTATUS =

Hi, I'm new to the forum and was clicking around a few of the pinned topics, and noticed that at least one has a dead link:

The link at the bottom is but I assume the forum migrated at some point to the new link format with viewtopic.php instead. Substituting viewtopic for showthread in the link pulls up what appears to be the correct link.

Maybe the DB could be search/replace for this to do...

Hi, I have some servers acting as Wireguard endpoints that need to accept traffic from certain ports and forward them to another host on a LAN at the other end of the Wireguard tunnel. Incoming data on the ports are accepted and forwarded to the appropriate host. Outgoing data is masqueraded. The TCPMSS clamp is required to ensure the forwarded packets respect the tunnel MTU. In this case as you...

Hello.

I hope everyone is safe and healthy.

The most recent update (Oct. 4, 2021) of ConfigServer wiped out all my previous settings. Does it make a backup somewhere?

Thank you.

but i only want to block ip A to access country CN.
how do we achieve that?

cc_deny , yes we can use that but for ip source A and B.. how do we only apply ip A?

I've got a user that keeps getting blocked for a custom LFD rule to block 3 consecutive Worpress failed logins within 3600 seconds. But they swear they are not getting failed logins. The rule is the widely published rule:

if (($globlogs{CUSTOM1_LOG}{$lgfile}) and ($line =~ /(\S+).*] POST \/wp-login\.php.* 200/)) {
return ( Failed WordPress login from ,$1, wordpress , 5 , 80,443 , 3600 );

Genuine transaction or website access or wordpress-admin updates are blocking csf with the following reason.

Temporary Blocks: IP:157.33.50.133 Port:80 Dir:inout TTL:518400 (Blocked port 80 with Directadmin Brute Force Manager)

How to prevent this or how to prevent the genuine traffics.?? its happening for all.
