When I ssh into machine B from machine A, I am asked for my password. But when I ssh into A from B, I am not. In both cases, id_rsa.pub from the other machine has been added to authorized_keys . And I see no difference in sshd_config or ssh_config . So why am I asked for my password when ssh-ing into B? -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
