General

Changes:

• Fixed csf –upgrade (csf -u) for DA installations

Changes:

• Added restrictions information regarding the PORTFLOOD setting and ipt_recent to readme.txt (i.e. hit count max is 20)
• Modular development of csf UI
• Added DirectAdmin UI and installation support for csf/lfd
• Added Statistics options (ST_ENABLE, etc) to generic csf installation
• Added SMTP options (SMTP_BLOCK, etc) to generic csf installation
• Removed pre-configured firewall settings through UI for redevelopment as it has become out-dated
• Modify csf UI to signal lfd to start/restart/enable only. A one minute cron job will actually perform the signalled function. The CLI is unaffected and performs the command immediately. This is introduced to overcome fork issues from within an Apache session

Changes:

• Added information about runing external iptables commands using csfpre.sh and/or csfpost.sh to readme.txt
• Added new CLI option csf –addrm (csf -ar) to remove an IP address from csf.allow and delete the associated iptables rules
• Removed the need for the MONOLITHIC_KERNEL option and made modprobe perform silently on csf startup. Added the relevant information regarding some Monolithic kernels and the need for a PASV port range hole to readme.txt
• Added timeout to csf modprobe to avoid startup hanging on buggy kernels

Changes:

• Added workaround for php –info bug in Server Report when checking PHP configuration settings
• Modified LF_INTEGRITY to regenerate the md5sum comparison file immediately after a match is found instead of waitng for the next cycle
• Fixed LF_INTEGRITY aborting if the temporary md5sum file is empty

Changes:

• Updated csf.conf to clarify that LF_PERMBLOCK_COUNT and LF_NETBLOCK_COUNT with act if more than the number of hits are detected, not on the exact number set
• Modified csf WHM UI to use csf -u to upgrade csf when a new version is available
• Added new script /etc/csf/csftest.pl which will test the servers iptables modules for functionality. The tests are for the required iptables modules and the optional modules for the SMTP_BLOCK, PORTFLOOD and MESSENGER features. This adds a useful diagnostic tool for kernel/iptables problems and to check whether the features above will function
• Added csf WHM UI option to run csftest.pl
• Updated the csf install.txt to run csftest.pl before running up csf

Changes:

• Improved detection of working ipt_owner iptables module on VPS servers such that if ipt_owner does not work SMTP_BLOCK and UID/GID blocks will be automatically disabled and csf will continue to start

Changes:

• Default setting for ICMP_OUT_RATE set to 0 – this is the recommended setting for cPanel servers which use ping times to determine fastest mirrors for various update functions
• Modified PT_LOAD_ACTION code to stop duplicate load emails from being send by lfd
• Moved ETH_DEVICE_SKIP to the top of the INPUT/OUTPUT chains
• Allow enabling of SMTP_BLOCK and use of UID/GID advanced port filter rules on VPS Servers for as ipt_owner is now apparently supported on the latest kernels. However, if the latest kernel isn’t being used or the VPS host hasn’t included the ipt_owner iptables module for the client VPS, then csf will fail with an error

Changes:

• Modified Process Tracking to allow regex exceptions in csf.pignore for deleted executable processes

Changes:

• Modified regex.pm detection of iptables kernel log lines to cater for alternative formatting
• Restored the substitution of the NULL separator with spaces for the /proc/PID/cmdline in Process Tracking
