Nessus 3.2.0 released
Hi there,

Tenable is proud to announce the availability of Nessus 3.2.0, as well
as NessusClient 3.2.0.

Nessus 3.2.0 is a major release, containing several changes from
Nessus 3.0.x :

New Features

- Support for IPv6 targets (for the Linux, FreeBSD, Solaris and Mac OS
X flavors)
- Support for limiting the number of active TCP sessions in parallel
(per host, per scan, per scanner)
- New "nessuscmd" tool lets one run quick scans from the command-line
- New "nessus-update" tool lets one update the Nessus engine from the
command-line (on select platforms)
- nessusd can now detect hosts which are being turned off during the
scan and stop scanning them
- nessusd can now detect when the network is congested and change the
TCP settings appropriately
- more granular user rules can be used to prevent the scanner from
connecting to certain ports or to use
certain plugins
- The 'nessus' command-line tool can read and write to and from
a .nessus file
- Improved WMI support (see


- New nasl functions can dynamically alter the plugin selection
- Improved memory management by NASL scripts
- Support for more SSH ciphers (AES-128/AES-192/AES-256/3DES)
- Improved service detection -- a new service detection plugin
(find_service.nasl) replaces the old find_service.nes
- On Unix systems, the initial plugin processing now takes advantage
of multi-core CPUs
- nessusd.rules now let you tune which plugins are forbidden for a
scan, and which ports can/can't be connected to

nessus_tcp_scanner specific improvements

- Simplified preferences -- a new cursor option (firewall detection)
lets the user better tune the scanner when running against a firewall
or a slow link
- Improved RTT estimation and congestion detection by regularly
probing unfiltered ports

Windows Specific changes

- NessusGUI.exe has been removed in favor of NessusClient.exe which is
now bundled with the installer
- It is now possible to authenticate the clients via SSL certificates
- KB saving and other options now work
- Installer now lets the users decide which components to install
(server, client or both)
- When the scanner is registered, it will automatically fetch and
process the new updates from every 24 hours

Mac OS X Specific changes

- Fixed a memory leak in the client
- Nessus 3.2.0 now is a real universal binary

Linux platforms

With Nessus 3.2.0 being a major release, now is a good time to stop
supporting some platforms and add support for others. Nessus is now
available for the following Linux platforms :

- Debian 4 (i386 and amd64)
- Fedora 7 (i386)
- Fedora 8 (i386)
- Red Hat Enterprise Linux 3, 4 and 5 (i386)
- Red Hat Enterprise Linux 5 (x86_64)
- SuSE Linux 9.3 and 10.0 (i386)

NessusClient 3.2.0 specific changes

- New 'network' tab when editing a policy which lets the user control
some Nessus 3.2 specific options
- Fixed several bugs which might cause the client to crash in the
middle of a scan
- Opening a large .nessus file in the client now takes less time
