[PLUG] Problems with password-less SSH

[Mike Leone <turgon@mike-leone.com>]

I had this working, between 2 hosts. Then I had to replace one of them, 
and I can't seem to get it to work anymore ...

What I need to do:
I need to execute a command on a remote server in my DMZ, and I have 
been doing this via cron. So user "vadmin@admnftp002" needs to execute a 
command as "FileCollector@192.168.1.30".

What I did:
As user "vadmin@admnftp002", I created new SSH keys, with no password. 
(I decided to make new keys, rather than keep the old ssh keys I used to 
use. This may have been a mistake ...I still have a copy of the old keys 
that worked on the old remote box, tho).

I did this by "ssh-keygen -t rsa". Then I copied the public file to 
"FileCollector@192.168.1.30" with

ssh-copy-id -i id_rsa.pub FileCollector@192.168.1.30

But when I try and test it, I get prompted for a password:

vadmin@admnftp002:~/.ssh$ ssh FileCollector@192.168.1.30 uptime
FileCollector@192.168.1.30's password:

Now, the remote machine is brand-new install of RHEL 5.4. I checked it's 
SSH config, and changed:

RSAAuthentication yes
PubkeyAuthentication yes
UsePAM no

and restarted SSH on the remote server, but am still prompted for a 
password. I am following these directions:

<http://www.debian-administration.org/articles/152>

This used to work, when the remote server was a Debian box. These were 
the same directions I used back then. But now it's a no-go. Any ideas 
where to find out why? I'm guessing I forgot something in a config, or 
missed a step, but can't figure out where. If I look in 
"~/.ssh/authorized_keys" on 192.168.1.30, I do see my 
"vadmin@admnftp002" key listed.

Thanks
