how get ssh to stop asking for passord?

How can ssh be stopped from asking for a password when log into a remote computer; it's only started asking after a silly do?

Thanks any help.

You'll need to setup private key encryption stuff to authenticate.

Installed / on remote computer and accidentally wiped /home partition. Would not then connect with ssh because it said the key, or something, had changed; so I wiped /home/.ssh I think, can't remember, and tried again. This time it worked but wanted the user password for the remote box.:rolleyes:

Thanks for the help - looks a bit bloody complicated, God knows how I managed it in the past.

ok, easy fix then. just cat the id_rsa.pub key from your client .ssh file into the "authorized_keys" file in the .ssh folder for your user on the server machine.

Make sure that the perms for that "authorized_keys" file are 600 and 700 for the .ssh folder.

The restart sshd on the server.

or delete the known hosts file from .ssh

or just delete the line from
~/ssh/known_hosts

is there a mechanism for public key based authentication in the known_hosts file? I didnt know that.

Thanks.

Used keygen to produce public private key pair and coppied the puublic one to authorised keys in other computer.
