AIX, SSH Key Exchange
Posted on 2011-09-22
I am trying to connect from my Ubuntu to my AIX box using ssh-key exchange to avoid having to authenticate. However, I am having trouble and keep getting a password prompt no mater what I try to avoid it.
- On my Ubuntu box, I have generated a pair of keys using ssh-keygen -t rsa to get pub/private keys.
- SCP'ed the public key to AIX box, added it to authorized_keys in the .ssh folder of the user that I will be logging in as.
- On my Ubuntu box, I run the below as root:
ssh -l nagios -i /omd/sites/oppy/.ssh/id.rsa.nagios 172.16.4.14 OppyCheck.aix
I would be expecting to login as user "nagios" on the remove box, however it asks for a password prompt. The pub/priv key was generated under the user nagios. I have tried generating it from the AIX box, and moving the private key to the Ubuntu box, no go.
Am I doing something wrong? I have this working successfully on my RHEL and VMWare linux boxes.
I looked on my AIX box the /etc/ssh/sshd_config and I see:
Back on AIX, I can see in /var/log/secure..
Sep 22 20:47:45 van-xxxx auth|security:info sshd: Failed password for nagios from 172.xx.x.xxx port 42272 ssh2
Any idea why this is not working?
