Hey guys,

It seems my server is getting a lot of failed SASL auth attempts via the maillog lately. This doesn't seem to be part of CSF's default configuration, so a lot of bad attempts got through!

I added a custom rule for LFD to ban these bad SASL people, but I highly suggest you make it part of the default csf.conf

Here is the tutorial I followed to implement the custom rules on my own...

Cyberpanel is a new and amazing opensource Control panel that supports Ubuntu and Centos.

It uses Postfix/dovecot for email.

Openlitespeed/Litespeed for the webserver.

Always after patching Dovecot CSF gives:

Cipher list []. Due to weaknesses in the SSLv2 cipher you should /etc/dovecot.conf and set ssl_cipher_list to explicitly exclude it. For example:
ssl_cipher_list = ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

This ssl_cipher_list parameter is set in /usr/local/directadmin/custombuild/custom/dovecot/conf/ssl.conf
And via build dovecot finally also in...

Hello,

I'd like to request that the automated abuse reports produced contain the destination (attacked) IP address in their opening line.

The reason for this is that CSF only takes the hostname as written in /etc/hostname , which is not an FQDN on many Linux distributions.

There is plenty of (unrelated) discussion about as to whether this file should contain an FQDN or only system name, but...

Hestia CP is fork of Vesta CP.

Vesta CP - Support added in CSF v13.05 ( changelog )
Hestia CP - Support will be added in which CSF version?

I was able to get CSF working on Hestia CP using the following simple sed snippet (from within the install directory):
find . -type f -exec sed -i 's/VESTA/HESTIA/g' {} + && \
find . -type f -exec sed -i 's/Vesta/Hestia/g' {} + && \
find . -type f -exec...

Since 99% of our CSF use is to block IPs it would sure be nice if CSF would remember what tab we have chosen. We always select the CSF tag to keep the Block IP field at the top, otherwise we have to scroll down to get to it. When we block an IP and return to the main page our tab selection is lost.

Thanks for an amazing product!

Currently, it is a pain to add custom port allow rules as they have to be crafted by hand.

I just noticed that the -ta, --tempallow option has this functionality. but the main -a add ip does not.

-ta, --tempallow ip ttl
Add an IP to the temp IP allow list (default:inout)

Possible root compromise: File /lib64/libkeyutils.so.1.9 exists and /lib/libkeyutils.so.1.9 exists.

For more information see:

This file is part of keyutils, part of the Linux kernel. If lfd is not checking the hash of the file matches a compromised version (it doesn't), then don't report it. This library has been around and been installed for years. Only when I updated to the 1.9 so version of...

Hi StopForumSPAM !

We are using ConfigServer Security & Firewall (csf) on server and we load the STOPFORUMSPAM with csf.blocklists

Since one week we have slow/strange/random issue with resolving domains:

(XID 5mjkwh) The system failed to send an HTTP “GET” request to “ because of an error: Could not connect to 'verify.cpanel.net:443': Name or service not known at...

Today I was delighted to realize that one can enter ASNs in the firewall and the respective ranges will be looked up and added. I had been looking up and adding ranges manually which is quite time consuming. But I was disappointed when it didn't work:

When the Watch System Logs page loads, the refresh function is automatically set to five seconds. I rarely find the auto-refresh helpful as I typically am scrolling up through the logs and lose my place when it refreshes.

I've been wanting a feature request for a switch to disable the auto-refresh either on the page or in the config. This could also include customization of the refresh...

The directadmin installation suggests that CSF config should be managed by the directadmin and we have to set some bruteforce settings to 0 or disable them. By doing this, the CSF will trigger few warning messages.

From what I've known, CSF use a special installation config file for directadmin called csf.directadmin.conf and it contains a generic variable DIRECTADMIN=1

If we can use this...

We've been getting quite a few Syn Flood attacks lately. This is not a problem when were are present as we can manually enable SYNFLOOD. CSF is a life saver and lets us sleep at night, but the one thing that's missing is the ability to have SYNFLOOD automatically enable itself when it detects an unusually high number of SYN packets occurring. And then disable itself when things return to normal....

Hello,

Would it be possible to include blocks from cPhulk brute force protection on the reCAPTCHA unblocking ?

That would be neat if feasible!

CSF is great but I'm missing a LF_TEMPBLOCK_ALERT = x option.

You can use the LF_EMAIL_ALERT or LF_PERMBLOCK_ALERT options, but since permblocks won't be automatically removed (normally) and I do want to be alerted about other options (which I guess more people would like), the tempblock option is missing.

Temblocks will be removed automatically and generate a lot of email alerts, which in a...

I have set up the following which someone may find useful:

2 x CSF Master in HA with 1 virtual IP - the master config has ALL slave server IP addresses and cluster key
100 CSF slave servers with ONLY the master ip in the clsuter settings + cluster key
A Master script which runs as a daemon and monitors the LFD log to rebroadcast only APPROVED commands to all slaves.

The advantage is that you...

Hello,

If Csf has already blocked in cluster an IP of C-Class, then it should not send one more request of an ip deny with -cd or even accept locally -d. I have a huge problem that there are doubles, one from 0/24 and then hundreds of IPs belonging to this chain.

Consequently, there are thousands of IPs in the csf.deny file.

I have csf on Centos 7.3. The C-Class blocking is activated after...

Would it be possible to specify the period over which the number of failures occurs PER REGEX. Currently, the LF_INTERVAL is used and applies to ALL regexes.

Is there any reason why the csf dev team have not added an md5sum for the csf.tgz download file to enable integrity checking?

It would be nice to have an option to be able to exclude a specific TCP or UDP port so that it is not affected by the CC_DENY filter
