I usually perform next steps to setup a passwordless login (all commands done on a client side, that is where you are connecting from, in your case "user" is the same that you are logged in on a client): $ ssh-keygen -t dsa -N '' -b 1024 $ ssh-copy-id -i ~/.ssh/id_dsa.pub user@remotebox In case there is no ssh-copy-id (for example, an older box) I use next: cat ~/.ssh/id_dsa.pub | ssh user@remotebox "cat >> ~/.ssh/authorized_keys" Testing: $ ssh user@remotebox ssh-copy-id comes with openssh client package. If that does not help I'd suggest you to check the contents of ~/.ssh/authorized_keys on remobe box if it contains some older keys for that user. If that still won't help I suggest you check the permissions of ~/ssh directories on both the client and the server sides. Certain files/directories should not have access to world, and definitely no write access to world. You can run next command both on the client and the remote box sides and show the output to us: $ find ~/.ssh -ls Cheers, VL
