The below instructions for installing rlogin have been confirmed for CentOS. This means there is a very high probability it is compatible with a registered copy of Red Hat Enterprise Linux 4 (rhel4).

ENSURE RSH PACKAGES INSTALLED

The first step is to insure you have the correct packages installed. To do this, simply type the following in the terminal.

rpm -qa | grep -i rsh

The following should return two packages similar to:

rsh-server-0.17-25.3
rsh-0.17-25.3

If you are missing any of the above packages, run the code below to have the appropriate two rsh packages installed using yum.

yum install rsh*

The most common changes are in red, though you should still confirm the rest of the file.
