I presume you're using an ssh-agent? Thanks very much. On looking at /var/log/secure on machine B I read: ----------------------------- Feb 23 12:47:19 blanche sshd[18050]: Authentication refused: bad ownership or modes for file /home/tim/.ssh/authorized_keys Feb 23 12:47:22 blanche sshd[18050]: Accepted password for tim from 192.168.2.1 port 41431 ssh2 ----------------------------- When I looked at .ssh/authorized_keys I saw that it had mode 664 (ie with group write permission). After changing this to mode 644, I am able to login without password. -- 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
