All right folks, I have another very basic question. Please bear with me.
I'm following the instructions at the following website to download and configure Hadoop on my computer.
http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/
I'm at the final SSH section, when I use the localhost command. When I run the following code, I get an error message.
hadoop@amathew-Dimension-3000:~$ cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys
hadoop@amathew-Dimension-3000:~$ ssh localhost
ssh: connect to host localhost port 22: Connection refused
Here's some other information which might be relevant.
hadoop@amathew-Dimension-3000:~$ ssh -vvv localhost
OpenSSH_5.5p1 Debian-4ubuntu5, OpenSSL 0.9.8o 01 Jun 2010

Can anyone help?
Once again, thanks for helping the newbie who just can't figure things out yet.
