If anyone is a die hard user of Nessus like I am, don't install this release just yet. It will only run in detached mode right now. I have opened a bug on the Nessus site so maybe 1.3.4 will address this issue.
PLATFORM & VERSION
RH Linux with Nessus 1.3.3
When you launch NessusWX (the Windows console for the scanner) and attempt a scan, the program terminates unexpectedly.
Run the scan in detached mode and have the results e-mailed to you.
On a positive note, this version scans a hell of a lot faster than previous versions. Also, debugging NASLs is most improved. It will even give you line numbers in the NASL when there is a failure of some sort.
Anyway, hope this helps!
