Knmap is a KDE-based interface to the 'nmap' facility available at http://www.insecure.org/nmap. The main Knmap window provides for the entry of nmap options and the display of nmap-generated output.
Loggrep greps kernel logfiles on ipchains and iptables firewall log entries and features the ability to filter against given entries (date, IP, port, ..).
It also features quasi-detection of protscanning, line count
and html output.
