To turn them on for cluster access on the server, do this:
chkconfig rsh on
chkconfig rlogin on
chkconfig rexec on
To turn them on for cluster access on the clients, do this:
cexec /sbin/chkconfig rsh on
cexec /sbin/chkconfig rlogin on
cexec /sbin/chkconfig rexec on
Note that if pfilter is running, it will still block access to rsh/rlogin/rexec from sources outside the cluster. To allow anywhere to access rsh you have to add a line like this to the /etc/pfilter.conf file:
open tcp 514 # allow rsh into this machine from anywhere
or you could add this line to allow rsh access from a couple of machines and an address range:
open tcp 514 from machine1.domain.org machine27.domain.org 1.2.4.0/24
I forget the ports for the others, but it's similar, just don't forget to do:
service pfilter restart
to make the new configuration active.

Is there a way to get the default installation of Oscar to turn on rsh, rlogin, and rexec? I would
use ssh happily, however, Gaussian 98 uses SCA's LINDA. LINDA (message passing library) uses
rsh, rexec, and rlogin to initiate jobs. What config files do I need to modify? I tried just modifying the files
in /etc/xinet.d but that didn't work. rsh-server and rsh is in the rpm package list and installed.
Thank you,
