Try using the -v or -vvv option to either scp or ssh. This (Very Very)Verbose mode should tell you what is (not) happening.

Edit: You might also look here: http://linuxcommando.blogspot.com/20...-checking.html

(link lifted from http://www.linuxquestions.org/questi...ements-760292/ )

and tell us how much you know about this remote server, is it yours? Do you administer it? Have you changed anything on it recently?

Off hand I would suspect that the key file in your .ssh is missing, or the .ssh directory on the other machine got messed with. Either the authorized_keys file, or the .pub files got moved.

Check the permissions on the .ssh folder. Make sure they are owned by the user you are trying to SSH with.
