Hi Suresh,
His machine is in on different subnet /block. I finally found
authorised_keys file in which he had an entry. I renamed the file.
BTW, is it okay to leave the renamed file in the same directory? Can ssh
be made to lookup a different file for authorised keys from a client's
side?
Thankyou.
