Actually, Foundstone has release a new version of SuperScan just this
year. We played with it during the ultimate hacking bootcamp and it's
pretty sweet. The scan results can be converted to various formats
just like Nessus Scan Results.

I would think that your problem is with the -O flag. A lot of
people have
reported similar behaviour with the O/S detection.

Fortunately the admins were not upset. They looked through
the services on
the servers, looked which ones had gone "stopped" and set
them back to
"started".

In general point to watch on Oracle--

Oracle listeners are extremely fragile to invasive interrogation.
I have brought down Oracle listners repeatedly with a variety
of port scanners that do OS detection. Wish I could remember
the exact Oracle versions, at least as recent as 8 and 9i,
and primarily running on *nix. (Linux, AIX, and OpenVMS; of
course, with VMS's own native buggy and third-party IP stacks,
just about any port/vuln scanning activities is liable to bring
those things down.)

Interestingly I have not seen this same behavior on Oracle on
Windows. Anyone else?
