IBPan 1.9.0

Last update 2023-10-11T15:28:00Z

This release contains firewalld support and makes firewalld the default firewall for Linux. The public zone is used for all the rules along with firewalld ipsets to store the ip addresses of each rule.

Also added a timestamp_utc option for parsing of event viewer and log files. If used, the timestamp will be assumed to be in utc time and not local time, unless a time zone is explicitly in the parsed timestamp, in which case that will be used.

• Don't log config error if config item is missing or empty.
• Logging for ignored internal ip addresses and why they were ignored.

• Attempt to fix possible Linux timer issue for running cycles.
• Ensure legacy iptables is used on Linux.
