I have found that in Volatility 2.1 and 2.2 connscan is not supported for profile Win7SP1x86. Volatility 2.0 does not produce any results. (??)
I see that sockets and sockscan are also not supported in Volatility 2.2. See below.
 
pslist does work, so some commands are supported.
 
Is this a known issue?
