[NBLUG/talk] Can't ssh to Ubuntu using PuTTY

First thing that would be a good idea is to run the following command on the
Linux box: 

ps -ax | grep ssh

You should see something like this:

5513 ?        Ss     0:00 /usr/sbin/sshd

If you don't see anything, there is a high chance sshd isn't running. 

If it isn't fist just try running 

sudo apt-get install ssh

this will install the client and server. The ssh config files are in

The only other thing I can think of other than that is that you are using a
firewall that is blocking port 22.
