Hello,

We are facing issue of LFD daemon failure regularly.

In WHM, it shows running and enabled, but failed to start.

Following is the error LFD generate:

>> Starting ConfigServer Firewall & Security - lfd...​​
>> Error: You have an unresolved error when starting csf. You need to restart csf successfully before starting lfd (see /etc/csf/csf.error)​​

Receiving permissions error via CRON on daily basis:

The Log Scanner Report emails contain lines of data from the log that appear to be continuations of previous multi-lined log entries.
It appears that the format of the log entries looks like:
-------------------------------
begin with the date/time in brackets
a space
the type of log entry ( info, warning, error)
a space
a source ( program or procedure ) of the log entry in brackets

Hi,

On my system (Debian 7) the day is padded with a space when the day is a single digit.
Then this line #262 in RegexMain.pm will not match:
if (($config{LF_FTPD}) and ($globlogs{FTPD_LOG}{$lgfile}) and ($line =~ /^\S+ \S+ \d+ \S+ \d+ \ \ FAIL LOGIN: Client (\S+) /)) {

Might be a typo. It works for all two digit days.

I changed it like that and it works: ^\S+ \S+\s+\d+ \S+ \d+ \ \...

Hi,

I'm finishing new adaptation of CSF to Webmin. I just found a small bug that breaks the table output:

Deny Server IPs->Change (this button's container is `td` and it has `colspan= 3 ` when it has to be `colspan= 2 `)

Hi,

In Webmin in all themes AJAX requests (Watch system logs and etc) return header and image, plus broken CSS and the loader is always spinning.

Please confirm.

Hello,

I've got CSF and LFD csf v9.11 running on my VPS server without problems until a couple of weeks now.
Every couple of hours or sometimes a day LFD create a zombie defunct process on my Directadmin vps server.
When i restart LFD the zombie is gone a couple of hours but then its back again. Is this a bug in LFD?
Is there a way to debug LFD or do you have any idea where to look and to...

I noticed that the Log Scanner Report is not sent on a daily basis as it is configured. So one day i receive the report the other day I do not receive the report.

I observed this behaviour on two servers. I already removed CSF and re-installed it but no way. It still sends the reports randomly.

Checked also the crontab list but did not find any abnormalities.

Do you have any idea where...

Hi,

LFD sends fixed 0 as timeout to the cluster members:

/usr/sbin/lfd line 7496:
if ($config{CLUSTER_BLOCK} and $config{CLUSTER_SENDTO} and !$cluster) {&lfdclient($perm, ,$ip, $port , $inout , 0 )}

It shoud be:
if ($config{CLUSTER_BLOCK} and $config{CLUSTER_SENDTO} and !$cluster) {&lfdclient($perm, ,$ip, $port , $inout , $timeout )}

I'm using csf:v9.11

Csurgi

In the csf.conf file, you have the comment:
# Allow incoming IPv6 TCP ports

... but then:
# Allow outgoing TCP ports
# Allow incoming UDP ports
# Allow outgoing UDP ports

You should update the latter 3 to:
# Allow outgoing IPv6 TCP ports
# Allow incoming IPv6 UDP ports
# Allow outgoing IPv6 UDP ports

Sometime yesterday CSF firewall stopped logging AUTHRELAY alerts and stopped sending notifications. I updated to the latest version of CSF but that functionality is still missing.

This is actually in reference to another bug that was recently fixed.

9.07 - Fixed removal of complex allow and deny rules

It appears that these changes are preventing complex rules from being removed when using the IP address itself. This complicates things when iptables rules generated for LFD automated blocks are entered. As an example:

tcp|in|d=2078|s=1.2.3.4 # lfd: (cpanel)...

Hi,

Its look like there come some problems when my installation upgrade to 9.07

Hello,

Recently I enabled the IPv6 support in my office and because of that I decided to also start to enable IPv6 support on my servers too.

But after I configured everything I notice that the connection to ports that are in CC_ALLOW_PORTS_TCP are always going through IPv4 and never through IPv6. So I listed in IP6TABLES and IPTABLES I notice that the Chain CC_ALLOWPORTS is empty in...

Did the new updates break csf -ar and csf -dr functionality? They don't appear to be working for me.

Hello,

At the end of a fresh installation I get the message :
