How to enable telnet?

hi experts,
I installed redhat linux 5 2.6-18 kernel version in one server.
It installed successfully, everything goes correct except telnet.
It is not telnetting.
I was surprised that in /etc directory inetd.conf file not available.

i am using that server through SSH, now.
How to enable telnet in that server?

You need to install telnetd. It's on your install disks or from the internet. For Redhat, "up2date telnetd" should do it. For a more general discussion of why it isn't there and getting it on various Linuxes, see my

Telnet transmits everything in the clear. Anyone with a sniffer can see whatever is being transmitted (including passwords) when you use it. It should be avoided if at all possible. SSH is the correct tool to be using.

Starting with RHEL5, RHEL no longer uses up2date it uses yum instead.

Make sure to say RHEL5 and not RH5. RH5 is an older product and has not been supported for 10(?) years. RHEL5 is a current product and will have support until at least 2014. They are vastly different(essentially unconnected) products.

If you insist on using telnetd (definitely NOT recommended, as said above), the settings are in /etc/xinetd.d dir.
