OpenVAS-Client is a terminal and GUI client application for OpenVAS. It implements the OpenVAS Transfer Protocol (OTP) which has superseded the Nessus Transfer Protocol (NTP) in OpenVAS. The GUI is implemented using GTK+ 2.4 and allows you to control an OpenVAS server, to conduct network vulnerability scans and to manage the results of your scans. OpenVAS-Client is a successor of NessusClient 1.X. The fork happened with NessusClient CVS HEAD 20070704. The reason was that the original authors of NessusClient decided to stop active development for this (GTK-based) NessusClient in favor of a newly written QT-based version released as proprietary software.
