Question : root access b/w servers

I know this might be an obvious one, but I've been doing a workaround for sometime now, but I'd like to find out how to allow root access between servers.

Scenario:

Got a RH server and want to run an installation "from" a Solaris Machine, however the installtion files are owned by root (and the permission can't be changed) - so naturally when you attempt to read or execute these files, you get the "permission denied" message.

how can I allow root privilges for root (or any other account) from another server?

Thanks

Answer : root access b/w servers

You could also create a .rhosts or hosts.equiv file on on your RH server that 'trusts' access from your Solaris server.   Be careful with this option though.  A lot of admins don't like this because it is susceptible to IP/servename spoofing.     Secure Server (SSH) methods like Wool suggests above are more secure and preferred but this is a quick and easy alternative.
