set up of ssh keys

[kjsys1]

Is anyone running on their AIX Unix servers sshd with Secure Shell (lslpp -l |grep -i ssh produces:
SSH.Secure.Shell 3.1.0.0 COMMITTED SSH Secure Shell Server
SSH.Secure.Shell 3.1.0.0 COMMITTED SSH Secure Shell Server
)

A couple of servers use the OpenSSH and I have not yet been able to create the ssh keys correctly to be able to run commands w/o the password from one server (w/ Secure Shell) to the other server (w/ OpenSSH).
Any ideas?

it works. you need to meet some requirements:

- the remote user requires rlogin=true
- the home directory must be owned by the user with rights 755 otherwise you need to set strictmode=no in sshd_config
- if the remote user is root, then permitrootlogin in sshd_config shoud be set to yes
- ~/.ssh rights should be 700
- ~/.ssh/authorized_keys rights should be 644 or 444


I think that's all. If not please let me know.

btw. there is a latest openssh version compiled for AIX (in bff package for AIX 4.3 and AIX 5.2) you can get it from

http://www.zip.com.au/~dtucker/openssh/openssh-4.1p1-1-bff.tar.gz

and to create ssh keys try this:

ssh-keygen -t rsa

or

ssh-keygen -t dsa

It will create default named protocol 2 keys (pairs) in ~/.ssh/ direcotry.

when prompted for password just press enter to set it empty.

If you would set passwort for the keys then to ssh w/o the password you will need to use ssh-agent.
