automate file access on server using SSH and passwordless access

My concern is to execute cvommand and access files in directory which
is on the
server. I want to execute those files from the local machine via ssh
and
for this i need to have a common key so that i dont have to keep making
different keys all the time

If u have a solution or a cookbook kind of a thing for this please help
me

When I set up no-passwd for root so I could do rsync backups with ssh
on the LAN, in root's home dir I did something like this:

ssh-keygen -t rsa

This should create the files:

..ssh/id_rsa
..ssh/id_rsa.pub

Then I copied id_rsa.pub as .ssh/authorized_keys2 to my home dir on the
remote host.

There's a little bit more.

Your (remote user's) home directory can't be readable by anyone but the
user, or the login will still require your password. It can be
executable but not readable. I personally would make your .ssh
directory be mode 700 too.

I would advise against allowing root to ssh in, I think it's safer to
set up sudo and then make it so root must use the local terminal.

You're saying "access" and "execute" both. Presumably these are
scripts and you want to run them from remote?

Thanks to Ken and Nietzsche for their thoughtful replies.

Just to add, should you are on windows OS, automating "putty" can be
little daunting. You can get a fantasic cookbook sort of guide here at
http://www.unixwiz.net/techtips/putty-openssh.html . It provides a full
passwordless, agent-based access that requires no step in contrast to
regular passworded access to system. "psftp" will help you for access
files on remote system when agent in on the run. You can even automate
the "passphrase" input including the sessions here.
