I may be wrong, but I believe that if you've just installed 'unbrickable', the default password for root is 'rootme'.
You'll have to reboot your iLiad before attempting to log in, in order to start up the ssh server.
Also, make sure you're using PUTTY in SSH mode, not simple telnet mode. My usual way for connecting to the iLiad is:
Code:
$ ssh root@192.168.1.102
root@192.168.1.102's password: rootme
(Obviously I have changed my password to something else.)
If you can successfully ping the iLiad then this should work...
