ConfigServer Community Forum

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...

Hi I've done some searches and saw a few hits:

I'm fairly new to defending my own server against attacks and thought that it would be helpful to automatically populate csf.deny with data from various blacklists. The above search results show this has been brought up a few times, but it seems the conclusion is there is too much data to effectively do that with csf (limitation of software...

The service “lfd” appears to be down.
The system’s command to check or to restart this service failed.

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.

helo
lets say our server has 2 ip A and B.
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?

Hi

I am actually satisfied with ConfigServer MailScanner Front-End. We get a lot of Phishing emails these days. i searched for what i can do better, and I came across here.

Phishing Updates
These scripts will allow you to update your MailScanner Phishing safe and bad sites. The data files are updated four times per day. To use this service simply replace the respective cron files. These files...

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.

Sorry if this is a dumb question, but what's the difference between the DYNDNS_IGNORE and GLOBAL_DYNDNS_IGNORE settings in csf.conf?

I would like to know if is possible to remove the emails I would select when using the Bulk Actions on the Menu.

when I click on the MailControl option and open all the emails logs, sometimes it goes up to a large amount of the emails and the pagination goes to a lot of pages.. As I really enjoy the option to disable the No Pagination (Danger) as it would list all emails on the same page, I...

Can someone help me?
I can't login to csf admin page when i setup it to a external app proxy in openlitespeed. When i login, alway return to login page, in debug mode, log print request data is null in spite of request data in my browser is correct csflogin and csfpassword. In direct access to csf admin page, login is normal.
So sorry for my bad English. Thank for all.

Hi,
I have blocked an ip xx.xx.65.81 but i can still see ddos attack from that ip.
csf -l shows that DROP rules have been added as shown below:

200 2 1450 DROP all -- !lo * xx.xx.65.81 0.0.0.0/0
200 4 1840 LOGDROPOUT all -- * !lo 0.0.0.0/0 xx.xx.65.81

The IP is present in the /etc/csf/csf.deny file. lfd and csf both services are running.
csf version is v14.10

Is there anything else i can...

Hi, would love to see integration with crowdsec

It would make CSF SUPER powerful and leverage the crowd

Hi there,

Just wondering if anyone's run into this, I can't find anything directly relevant in the search at least.

We use the SMTP_BLOCK option by default with our whm server and allow exceptions for some users. We had quite a few users listed under SMTP_ALLOWUSER and I thought it may be easier to set up groups and simply put the groups in SMTP_ALLOWGROUP instead of having a disorganized...

Hello there!

I'm newer here, but I have used CSF for a while, and recently we are having problems with spam.

I get the authrelay notification from other countries and when I change the passwords of the compromised account the problem stops, but I would like to stop this definitely, so I tried to fix it by using this configuration:

cc_deny_ports = RU,CN,KR
cc_deny_ports_tcp = 587,25,465...

Hi,

I have been trying to configure CSF and Docker under a Plesk server. There are many posts in forums reporting that when Docker creates a NAT redirect to certain port, that port is exposed to the entire world.

I tried to use this csfpost tool but apparently It hasn´t worked.

In some way, installing netfilters tool for saving iptables rules I have managed to store a set of iptables rules...

Hello.
CSF plugin is installed on the Directadmin control panel.
Recently, possibly after updating the CSF, when performing a backup from the panel via FTP, we found that connections were blocked on the allowed port.
Configuration:
