very simple, you should setup .rhosts files:
Configuring .rhosts
It is even beter to use ssh, rsh sends everything in plain text over the line and is known to have some security issues. (but this is only an advice..)
When you use ssh-keys you get the same results but safer..

RSH(1) General Commands Manual RSH(1)
NAME
rsh - remote shell
SYNOPSIS
rsh [-n] [-l username] host [command]
host [-n] [-l username] [command]
DESCRIPTION
Rsh connects to the specified host, and executes the specified command. Rsh copies its standard input to the remote command, the standard
output of the remote command to its standard output, and the standard error of the remote command to its standard error. Interrupt, quit
and terminate signals are propagated to the remote command; rsh normally terminates when the remote command does.
The remote username used is the same as your local username, unless you specify a different remote name with the -l option. This remote
name must be equivalent (in the sense of rlogin(1)) to the originating account; no provision is made for specifying a password with a com-
mand.
If you omit command, then instead of executing a single command, you will be logged in on the remote host using rlogin(1).
Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote
machine. Thus the command
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the localfile localfile, while
rsh otherhost cat remotefile ">>" otherremotefile
appends remotefile to otherremotefile.
OPTIONS
-l username
Specify the remote user name.
-n Connect standard input of the remote command to /dev/null. Do this if rsh should not inadvertently read from standard input.
SEE ALSO
rcp(1), rlogin(1), rhosts(5).
BUGS
You cannot run an interactive command (like rogue(6) or vi(1)); use rlogin(1).
