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, sorting, filtering and csv file save. 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.
• The connections list can be filtered.
• 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.

• Multiple connections list snapshots can be saved in a formatted text file or in a csv file.
