But when I run the scan nothing seems to happen. Meaning no new vulnerabilities appear compared to a Nessus scan that doesn't have Nikto enabled.
The only information I was able to find in nessusd.messages was the following:
launching nikto.nasl against 192.168.0.125 
nikto.nasl (process 1251) finished its job in 0.010 seconds
This seems incredibly fast compared to running Nikto from the command line, which works fine. Does anyone have any ideas on how to get this working, or where on my system I could check to find additional information on what is happening?
I'm running CentOS 6.4 x64 and Nessus 5.2.
