Passwordless RSH and a Noob

Ok i managed to get something correct.

I want 3 pc’s to rsh passwordless between then and to themselves. One is the master pc and two is worker pc’s.

on a linux machine, what is your username and your machines name, cause when i open a shell it says for example Derick@Concord with a file named Derick being found under the /home/ directory. Is Derick the username and Concord the computer name

The two worker pc’s are setup identically (hardware and software), the only diffirence between them is the computer name. They can rsh to one another and to themselves.

My master machine is a more powerful machine and has the same software as the two worker pc but has a totally different username. With this pc i am able to rsh passwordless internally but not to the other machines.

And when the master pc rsh’s the other two machines or one of them rsh’s the master pc, i am prompted for a password, but when i type in the normal login password for the particular machine it doesn’t accept it. After two attempts i am prompted for the user name (of the machine being rsh’ed) and password and onloy then can i log into that machine? Any idea’s whats wrong?

I also noticed that when i remove all entries from the /et/hosts.equiv file the two worker pc can no longer rsh passwordless like the .rhosts file is being ignored? Is there a problem with this file and should it be placed in the directory: /home/Derick

Any help would be greatly appreciated.
