UnixCMD - example 6

[Gqcy <gmufasa01@xxxxxxxxx>]

I have just downloaded and starting to work with this...

I think I have SSH set up properly,

I am executing the example6 program which attempts to run the following 
command:

 cmd = 'ssh xxxxxx3.xxxxxxx.com ps axww "|" +
        grep boxrelay "|" grep -v grep';

and I receive:

 ssh: xxxxxxx.xxxxxxxx.com: Hostname and service name not provided or 
found



The system i user I am using is set up in SSH (has a .ssh directory)
( I got a "go away!" message with a different profile)


Does this message mean that I need to have some key?
