Hello, -1 tells ssh to try protocol version 1 of ssh, that's not what you want to do. You want to log in as root user, so you've better use the '-l' with an 'l' like in 'login' as the option.
Alternatively, you could do : $ ssh root@Mcgibbney-PC Provided Mcgibbney-PC is resolved as a hostname (try "ping Mcgibbney-PC", if that works, you should be fine) Hope this helps, -- Tanguy 2011/1/25 McGibbney, Lewis John <lewis.mcgibb...@gcu.ac.uk> > In getting Nutch 1.2 up and running with Hadoop should I be using the > tutorial on the Nutch wiki (1), this tutorial link (2) or the link to the > hadoop cluster setup (3) > > I am using 2 desktops (one running Vista and one running XP) with Cygwin to > execute commands and wish to experiment running a hadoop tutorial.
