unfortunately, you're not telling us what "your system" is. However, many distros don't set a password for the root account, and generally disallow login for accounts with no password. So probably all you have to do is to give root a password:

Code:

sudo passwd root

Note that root may still be excluded from GUI login, as this is strongly discouraged for various reasons. The above only allows root to log in to a console.

If you're logging in via SSH then you'll also need to check your sshd_config and ensure:

Code:

PermitRootLogin Yes

Check your /etc/login.defs file.

Red Hat disables root-login for the GUI for very good reasons, and the hacks need to enable it are not safe. See this thread (ignoring the off-topic bits in the middle)

BUT
this is the very very old and antique RH5
rh5.0 was released in 1997
i am suprised that the almost 20 year old ( 18 year) hardware and OS are still working
rh5 is 4 full generations out of date and is older that Win98

this predates the redhat blocking on RHEL 7.0

on the CURRENT
RHEL 5.11
RHEL 6.6
you can login as root into the Gnome2 desktop you are sitting in front of

the first thing to do is buy hardware newer than 20 years old
then install a modern Operating system

contact redhat sales for
RHEL 6.6 or RHEL 7.0
