RE: Scan Issue

But I stopped the scan after almost 15 hours: do you think if waited longer,
the test could have been completed??!

Also, if I deselect Nmap, how do I cover the UDP port scanning

Thanks,

Bilal

IMHO, it did not hang, it is just awfully slow.

You found the solution by yourself: deselect Nmap.

I suspect that the timing options are badly broken in the last version(s). A
couple of days ago, I scanned a friend machine. 
nessus_tcp_scanner was four time quicker: 
380 s with nessus_tcp_scanner, 1500+ s with nmap -T 4 ("aggressive"
timing) 

Maybe we should add --host_timeout when we launch Nmap?
e.g., if thourough_tests are disabled, we give it only half an hour to
perform the job. Anybody against this?
