passwordless ssh not working on rhel5
Was doing automation test, trying to set up passwordless ssh between the dirver and couple of test nodes. it just didn't work with one rhel5 box. Finally find the solution:
[root@perlrh5-179 .ssh]# tail -n 10 /var/log/secure
Dec 4 12:39:56 perlrh5-179 sshd: Authentication refused: bad ownership or modes for directory /root
Dec 4 12:39:59 perlrh5-179 sshd: Connection closed by 10.200.58.179
log shows the issue was the permission of the root dir
drwxrwxr-x 20 root root 4096 Nov 25 10:08 root
change it to 700 and the issue was resolved.
