rsh/rlogin setup:

1. Install the "rsh-server" RPM
2. chkconfig rsh/rlogin on
3. vi /etc/securetty - Add rsh/rlogin (seperate lines) to this file
4. vi /etc/pam.d/rsh - Change "required" to "sufficient" for pam_rhosts_auth.so

Sometimes a program needs or was setup to use rsh/rlogin. Yes it's unsecure and has the "password in the clear" issue, but it's your choice on what you wish to use.

rsh

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).
