Anyone rcp to another computer using root?

I am not sure if this is possilbe because mine kept on timing out and i can see the two computers trying to contact each other in the message log. Both computeres are using SuSE 7.3 with firewall2. I have added the .rhosts file in root's home directory and edited the hosts.equiv file. Is there something that i am missing or it is impossible to do? thanks henry
