Neither. The line "127.0.0.1 localhost.localdomain localhost" should
already be in /etc/hosts and your Linux box doesn't care about the
Roadrunner IP address since its the outside address of your router.
/etc/hosts is just a text file so use your favorite editor to add
"w.x.y.z your.computer.name" where w.x.y.z is the IP address of
your Linux box, not the Roadrunner address assigned to your router.
your.computer.name is whatever you want to call your computer.
I'm not sure how it would work connection from outside your router
but this should allow you to connect from any computer behind your
router.

It sounds like in.telnetd may have crashed. Check /var/log/messages
for any error messages.

I don't think you can manually start the telnet server. I believe
that it was written to be started by the super-server (inetd or xinetd)
so it expects a socket connection where stdin and stdout would be.

Yes. If 192.168.1.4 is the IP address of your Linux box. To verify
the IP address, check the value that appears next to "inet addr" in
the output of "ifconfig eth0".
