New csf v5.00

Changes:

• lfd Clustering, final release. This new set of options (CLUSTER*) in csf.conf allows the configuration of an lfd cluster environment where a group of servers can share blocks and, via the CLI, configuration option changes, allows and removes. See the readme.txt file for more information and details, setup and security implications
• Added new option LF_DISTATTACK. Distributed Account Attack detection. This option will keep track of login failures from distributed IPs to a specific application account. If the number of failures matches the trigger value, ALL of the IP addresses involved in the attack will be blocked. This option is currently disabled by default – see csf.conf for more information
• Added new option PT_USERKILL_ALERT if you want to disable email alerts for PT_USERKILL triggers. This option is enabled by default, i.e. alerts are sent
• Added new options LF_QUICKSTART in csf.conf and CLI options -q, –startq, -sf, –startf to allow deferral of csf startup to lfd instead of waiting for the CLI to perform the work. See the CLI help and csf.conf for more information
• Added UI option for “Firewall Quick Restart” which uses csf -q, “Firewall Restart” uses csf -sf
• lfd now restarts csf (if stopped and LF_CSF enabled) within the main process to enhance the integrity of the firewall
• Multiple login failure regex detection improvements
• Fixed typos in permblock.txt
