cPanel

New release with:

• Added to APF/BFD removing in WHM UI the logrotate configuration files
• Added comments system to csf.allow and csf.deny – see readme.txt for more information

New release, new major feature:

• Tighten up some of the csf rules
• Added new fature – LF_SCRIPT_ALERT when enabled will scan /var/log/exim_mainlog for extended exim logging lines that show the cwd= line for paths in /home which indicate emails sent from scripts. If LF_SCRIPT_LIMIT emails from the same path are sent within an hour, an email alert is sent using scriptalert.txt containing the first 10 probably exim mainlog line matches and also likely mailing scripts within the identifed path – an ideal tool to help identify spamming scripts sending out email through exim. The option is disabled by default as you do need to enable extended exim logging first as
  

New release with a nice new feature:

• Modified lfd to use a child reaper instead of ignoring the CHLD signal
• Added login failure detection of cpanel, webmail and whm connections – this will only work for access to non-secure ports as cPanel doesn’t know the IP address of the user when connection are over SSL due to the way stunnel works

Released to fix a problems for VPS servers

New release with a new feature that can reduce your overall risk exposure:

• Removed erroneous ‘s in lfd.log
• csf start automatically does a restart to avoid problems with any existing iptables rules or chains
• Added new option “Deny Server IPs” and associated file csf.sips to allow blocking of all traffic on server configured IP’s if they’re not in use
• Added notification to CLI and WHM UI if TESTING still enabled

I will have a break soon 😉

• lfd modification to avoid a race condition with the ALRM calls
• Added new feature – /etc/csf/csf.ignore can contain IP addresses that are ignored by lfd. If an event is triggered it may be logged in lfd.log but will not result in an email alert – e.g. you could list your own IP address to avoid alerts from when you login over SSH, etc
• Added WHM UI option to edit the ignore file

Bug fix release and I’ve included the changes for v1.54 too:1.54:

• Fixed a strict refs issue in lfd

1.53:

• Fixed IP DNS lookup routine to avoid empty () when no host found
• Added local DIE for ALRM calls for IP lookups and netstat commands
• Removed chkservd restart from /etc/init.d/lfd so that it behaves like other monitored services
• Improved error trapping routines to better report to lfd.log if the process dies

A new version of csf. I’m going to take a development break for a while, though any problems with the scripts/firewall will be worked on immediately. The new features:

• Optimised logging in lfd
• Improved error handling and reporting in lfd
• Modified WHM UI report to include all data, not just a single day
• Improved DROP logging to SYSLOG
• Added logging of dropped ICMP connections
• Added new option DROP_IP_LOGGING to log IP addresses that have been blocked in csf.deny or by lfd with temporary connection tracking blocks

New version of csf released with the following changes:

• Added new feature – Connection Tracking. Enables tracking of all connections from IP addresses to the server. If the total number of connections is greater than CT_LIMIT then the offending IP address is blocked in csf, or temporarily blocked in iptables. This can be used to help prevent some types of DOS attack
• Added new feature – SSH login alerts. An email is sent if a successful
• SSH login is detected
• Fixed a descriptive issue with the WHM UI
• Modified so that lfd checks that it doesn’t block a server IP

Upgrade as usual through WHM.
