Graphical network connections viewer for Linux - Netactview

Netactview is a graphical network connections viewer for Linux, similar in functionality with Netstat. It includes features like process information, host name retrieval, automatic refresh and sorting. It has a fully featured GTK 2 graphical interface.

Features:
 * Shows all udp, tcp, udp6 and tcp6 network connections in an automatically refreshed list.
 * The presented information includes protocol names, addresses, ports and connection states along with host names and process information.
 * The connections list can be sorted by any of its columns.
 * Refresh rates ranging from 1/16 to 4 seconds, or no automatic refresh can be selected.
 * Connections can be seen for 3 seconds after they are closed giving you the chance to spot connections that last very little time.
 * The unestablished connections can be filtered out.
 * Multiple connections list snapshots can be saved in a formatted text file.

Installation:
Ubuntu packages (Ubuntu 6.06 or newer)
Standard PC (x86): netactview_0.5.1-1_i386.deb
