I just setup a dell server w/ Redhat 7.2 but cannot telnet into the box. I've assigned the IP, gateway and mask no problem and can ping the box too. I thought telnet was setup on the OS from the get-go. Ideas?
 
The firewall is probably blocking port 23. Check that and also I beleive telnetd must be running. But for sure check the firewall. --Derek

Telnetd is probably being run through inetd or xinetd. If you don't see telnetd running, check /etc/inetd.conf (or /etc/xinetd.conf) and make sure there's a line for telnet and it's not commented out.
Of course, you really should be using ssh instead of telnet anyway, but that's another story...
 
jegner,

As already mentioned in earlier posts, you should check that telnetd is running and that the Firewall is not blocking access to port 23. Also, you might want to look at /etc/hosts.allow or /etc/hosts.deny if they do exist. I used to have this same problem in the past, and I altered the hosts.allow file to provide access control to my telnet. But these days, SSH is a better choice.

ase2dais,

To my knowledge, SSH is somewhat similiar to telnet, only that it is more secure. Telnet sessions do not use encryption, therefore one is able to sniff and listen on telnet sessions. This is a security issue as usernames and passwords are passed on in plain text. In SSH, data is encrypted, therefore the session is more secure.
