I know this question has been asked, but I'm certain I've done what all the other answers suggest.
- used keygen -t rsa to create id_rsa.pub in ~/.ssh/
- copied Machine A's id_rsa.pub to Machine B user's home directory
- Made the file permissions of id_rsa.pub 600
- added Machine A's pub key to authorised_keys and authorised_keys2: cat ~/id_rsa.pub >> ~/.ssh/authorised_keys2
- made the file permissions of id_rsa.pub 600
I've also ensured both the .ssh directories have the permission 700 on both machine A and B.
If I try to login to machine B from machine A, I get asked for the password, not the ssh pass phrase.
I've got the root users on both machines to talk to each other using password-less ssh, but I can't get a normal user to do it.
Do the user names have to be the same on both sides? Or is there some setting else where I've missed.
Machine A is a Ubuntu 10.04 virtual machine running inside VirtualBox on a Windows 7 PC, Machine B is a dedicated Ubuntu 9.10 server
UPDATE : I've run ssh with the option -vvv, which provides many many lines of output, but this is the last few commands:
