snake:
first, check that the ssh daemon is running on your N900


$ ps ax | grep sshd

it should show someting like

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

Like jd4200 and myself already suggested: give yourself a password.

$ passwd user
New pasword for user:
retype password:

(Your name on the N900 is always 'user')

Install putty, run it
It will ask for hostname or ip-address. That will be 192.168.2.2
for you (BTW: you don't have a DHCP server that can assign different IP-numbers?)

A black window will appear with 'username' (that will be user) and 'password for user' (that will be the password you assigned to user).

jd4200 and I have already said that enabling root login and logging in as root is a Bad Idea (TM). I will say it again.
