Iptqlog is the IPTables Queue LOGger. It produces clean, easy-to-understand, and (optionally) colorized logs of the packets that were sent to the user space using the QUEUE target in iptables. Its key features are resolving of IP numbers, port numbers, and protocol numbers, logging to standard output, syslog, or both, saving packets in pcap dump format and the ability to create your own output format.
|Operating Systems||POSIX Linux|
Release Notes: A new output format with aligned columns and no colors, ability to accept packages sent to the QUEUE target instead of silently absorbing them, support for logging only those packets that have a specific mark set by iptables, and optional resolving of service name (user-defined service names override system defaults).
Release Notes: This release adds support for saving the packets in a tcpdump-readable pcap format. Resolved host names are now cached to reduce network traffic. It is now indicated if a TCP packet has the SYN flag set.
Release Notes: New support for user-customized service resolving.
