passwordless ssh for non-root user???
hi all

I have a problem to set up the password ssh login for a non-root user. what I want to do is that non-root user in host A logs into host B without password prompted.

what I did listed as the following steps.

1. genarate a pair of keys from host A.
Code:
ssy-keygen -t rsa -N "" -f ~/.ssh/id_rsa

2.copy the public key to host B
Code:
scp -p ~/.ssh/id_rsa/pub hostb:~/.ssh/id_rsa.`hostname`.pub

3.create the authorized_key file from the public key
Code:
cat ~/.ssh/id_rsa.hostb.pub >> ~/.ssh/authorized_keys

after that, i have checked the permission both host A and host B. the .ssh has 700 in both hosts and the private key in host A has 600 and the authorized_keys in host B has 644.

when I tested the ssh connection, it still looks like this.

Code:
ontstcerwpar1racle.:/home/oracle/.ssh>ssh -v ontstcer2
OpenSSH_5.0p1, OpenSSL 0.9.8h 28 May 2008

any idea why this happens?

It might be an older version of SSH demanding DSA keys instead of RSA ones.

I think what you need, is to run ssh-agent.

I have a user that logs in without supplying a passphrase or a password, but when I first log in I run ssh-agent to cache the passphrase in memory.

If in fact you are using AIX, you might try:

Code:
   
   HOME=/
   export HOME
   /usr/local/bin/keychain $HOME/.ssh/id_rsa $HOME/.ssh/id_dsa
   . $HOME/.ssh-agent-$(hostname)

this command /usr/local/bin/keychain does not exit in AIX.

but I did checked the HOME for oracle user. it shows correct.

Try 'find'ing keychain.
