We need to install a package for the computer to handle listening services, one that's not normally installed by a workstation Linux installation. This is the inetd server, which listens for several daemons. On RedHat 6.2 installations, this is in the RPM inetd-0.16-4.i386.rpm. In earlier RedHat systems, such as 6.0 or 6.1, this was in the netkit-base-0.10 RPM.
On RedHat 6.2, these steps will install and turn on the inetd daemon:
rpm -ivh inetd-0.16-4.i386.rpm
/usr/sbin/inetd
/sbin/chkconfig inetd on
