Tenable Announces the Release of Nessus 3.0.1

January 8, 2006

Columbia, MD

Nessus 3.0.1 (build 114) is now available on our web sites.

Here is the list of changes in this release:


  • Lighter resources consumption of the master processes, which in turn improve scalability (one has to account for ~ 6 megabytes of RAM per host tested in parallel)
  • Reduce the CPU usage of nessusd when the only running plugin is executing a local command
  • Improved the timing of synscan.nes which could result in very long (nearly infinite in time) port scans
  • Slightly faster (~ 20%) initial processing of the plugins

Bug fixes:

  • When nessusd updates itself, the process now restarts properly
  • Fixed the error message "Warning this scanner seems to be using the plugin feed of another host" which would sometimes be displayed when the nessusd host changes of IP addresses
  • Fixed a NULL pointer dereferencement which may happen in some cases when dealing with shared sockets

Other :

  • Removed bogus warning messages occurring when max_checks is set to a very high value (which is not a good idea in the first place -- max_checks should be set to 4 most of the time)
  • KB files of hosts which are dead are not saved on disk (as they are empty)
  • Re-introduced HTML export, due to popular demand
  • The RPMs have stronger dependencies set
  • The SuSE 9.3 build is now linked to the default libdb 4.3

Thanks to everyone who contributed his feedback!
