"Don't let the simple look of NST's FluxBox desktop fool you.
Although the interface is plain and simple, a lot of powerful
network tools are at your disposal. Among the network penetration
testing and analysis tools included here are Kismet, Snort,
AirSnort, NMAP, and Wireshark. Nessus, a popular vulnerability
scanner, which is not included on the latest BackTrack release
(BT3) is included in this distribution. Network monitoring tools
like Nagios, Argus, and Zabbix are also included to help you keep
an eye on your network's health. In addition to its network
administration tools, the distribution hosts applications for email
(Pooka), chat (Pidgin), Web browsing (Firefox), text and graphics
editing and processing (ImageMagick, XPDF, Nedit, and others),
antivirus (ClamAV), terminal communications (GTKterm, Minicom),
remote desktop (VNC, TSClient), and data recovery (cfdisk,
Partition Image). I was surprised to find that this distribution
includes the free GPS navigation program GPSDrive. Both MySQL and
PostgreSQL databases are both included, and, if you need an email
server, so is Sendmail."
