Setting up SSH to accept authenticate hosts without passwords

jphaynes · 05-01-2002, 11:00 PM

I'm having trouble getting ssh to accept authenticated hosts without having to enter a password. Have any of you been able to do this?

Here's what I've done so far:
- copied my key from /etc/ssh/ssh_host_dsa_key.pub on machine one into the file /root/.ssh/authorized_keys on machine two. When I try to connect from machine one to machine two, it stills asks me for a password (which I don't want).

Thanks in advance for your help.

Hi!

I dunno SSH, but since you're already lost... :-)

Try removing the passwords of the hosts you want to connect to with:

passwd -d username

HTH...

vfs.

Actually, I just figured this out. You have to create new RSA keys on the host machine, and add the public key to the file called 'authorized_keys2' on the remote machine.

Then you can use ssh to run commands on the remote machine without having to enter a password. Which is really cool because you can then run commands like df to make sure hard drives on remote machines are not filling up.

See this series of 3 articles. It's very complete and a bit complicated but in the second article explain what you want to do.

Thanks! These look really good and the writer has written some really good artles about reiserfs and ext3 as well.
