Hi. We'd like to only allow FTP access to users who connect via a specific hostname like: portal4321.vps22.hostingserver.com.

And block everything which tries to connect to the FTP in a different manner, like ones who use the server IP or vps22.hostingserver.com directly.

Is this possible in CSF? If yes, great, how do i set it up?

Thanks!

In /var/log/messages I see many of these types of messages, in fact they are the only ones I see:
systemd-logind: Failed to remove runtime directory /run/user/0: Device or resource busy

When I google this message, the first result is:

which one of the posters seems to indicate could be caused by lfd.

Any further insight into this?

Good morning CSF Team!

We are currently evaluating if we can use CloudLinux's Imunify360 solution which has a CSF Integration mode.

In Imunify360, when it detects CSF blocked an IP, it will move that block from CSF to Imunify360, however it relies on the 'BLOCK_REPORT' function of CSF.

During our testing, we've noticed that sometimes CSF will block an IP but Imunify360 didn't see the block....

Hi.

After upgrading machines that uses CSF to cPanel v92, this notification started coming every second:

lfd on host.domain.com: SUDO login alert - Successful login from wp-toolkit to root

Setting Account Tracking to root or even disabling it seems not to work.

The binary has been whitelisted in pignore.

What could be done to stop this notification as it clogs the pipeline and eats up email...

I am looking at how to block IP addresses with CSF, and find that the following command suits my needs:
sudo csf -d 10.0.0.1 do not delete
The response that I get back from CSF seems to indicate that this has been added to iptables:
Adding 10.0.0.1 to csf.deny and iptables DROP...
DROP all opt -- in !lo out * 10.0.0.1 -> 0.0.0.0/0
LOGDROPOUT all opt -- in * out !lo 0.0.0.0/0 -> 10.0.0.1...

I updated my cpanel to the latest version and rebooted my server. CSF is up to date but the server can't even be pinged if the firewall is enabled. I ran the check on the iptables and the result says all good and csf should run on the server, but it won't.

Server: CENTOS 7.9 kvm v92.0.3

I have downloaded the last known good config profiles so if need be I can reinstall csf but I would prefer...

Hi I am trying to configure lfd Clustering in csf, however the fields are all gray outed and unable to fill any number.
I use cPanel + immunify360.
Has anyone overcome same issue? :confused:

I have an email address that is repeatedly checking my server, but that account is invalid (non-existant account), and I know that the person doing it is not malicious, but only stubborn for not updating their settings, can i skip that email address from being checked by CSF and dont block their IP?

I use directadmin by the way.

Since the new versions of DirectAdmin we have problems with using the API for CSF. T We didn't change our scripts and it works for years well.

Debugging DirectAdmin I see the next message:

/CMD_PLUGINS_ADMIN/csf/index.raw
Command::doCommand(/CMD_PLUGINS_ADMIN/csf/index.raw)
Sessions::touch:Command::doCommand:/CMD_PLUGINS_ADMIN/csf/index.raw): no sesssion filename is set....

I have this already for a longer time but nobody responded to my other thread (november last year).

It seems csf.pignore is not ignoring certain shoutcast processes. I get this email:

I have CSF on my server and I use directadmin. when a user has 2 login failure in wordpress website csf add code like this in .htaccess file:

# BEGIN Brute Force Login Protection

order deny,allow
deny from 178.63.180.101

# END Brute Force Login Protection

how can I increase the number of login failure for wordpress users?

In csf.conf I have
LF_IPSET = 1
LF_IPSET_HASHSIZE = 1024
LF_IPSET_MAXELEM = 65536

I have several public blocklists enabled, namely ABDE, BDEALL, SPAMDROP, etc., all of which have been working correctly on csf with ipset for several years. At this point, I don't recall precisely what I had to do to set it up initially. I thought all I did was uncomment a line in /etc/csf/blocklists to enable...

Hello Everyone,
Does anyone know if CSF process is monitored by Cpanel server manager? As some mornings i find CSF randomly stopped i want to make sure that the service restarts should this happen?

Thanks

Hello,

I have a cPanel / whm server with csf installed on it.I have csf configuerd to automatically report abusive ip addresses to abuseipdb blacklist it works fine however when i receive the email csf sends the blocked ip address has the wrong country for example csf just sends to me that

194.87.138.228 (RU/Russia/-) is blocked for a portscan however in this case Russia should be Germany...

Hello,

my server provider blocked 25 port, and I use external SMTP service for all outgoing mails. is there someway to setup CSF to send mail notifications via external smtp with required autorization? Thanks!

I am trying to standardize my servers better with Puppet. Puppet is very good at building files with multiple lines like csf.allow, but it is more difficult to add multiple values to a single line like the TCP_IN list in csf.conf.

I attempted to add partial lines to csf.allow, but that didn't seem to work:
tcp|in|d=22 # puppet - from csf-global-allow-ssh
tcp|out|d=8140|d=192.168.118.31 # puppet...

i am wandering if there is the possibility to block port scans hiding ports (may be block all countries?)
it is performed by icmp protocol ?
thanks

So if I whitelist some IP's from a country in the Firewall Allow IPs list and then add thata country code to the CC_DENY settings, will those whitelisted IP's be allowed access to the server?
