Hi,

I am trying to configure xinetd on RH7.1. When I am on the console of my
machine, I can telnet back to itself. But from another machine I get
connection refused. What could be wrong?

When RH 7.1 installs itself, it installs a firewall which is most likely
blocking your requests. You can try this and see whether or not it works:

/sbin/ipchains -I input 1 -s 0.0.0.0/0 -d <your ip> 23 -j ACCEPT

See if that allows telnet connections to enter your system.

See ya

You need to edit /etc/xinetd.d/telnet. It should be obvious what you need
to do, then restart xinetd.

Thanks Dean,

I just simply ran the firewall scripts with the stop option and it did solve
my problem. Thanks for the help

RedHat 7.1 comes with IPChain that blocks telnet port by default. That is
why you can telnet from your own machine but not the outside world.

If he has not edited /etc/xinetd.d/telnet, how the hell did he managed to
telnet to himself ?

Please bottom post on these news groups. I have taken the liberty of
moving your post to the bottom.

One can telnet to 127.0.0.1 even without a telnet server being present.
Only the telnet client is required.

If one wishes to be able to accept telnet connections on port 23 from other
hosts it is required on RH-7.1 that the /etc/xinetd.d/telnet file be edited
and xinetd restarted, plain and simple.

There are other commands which will restart xinetd and if Red Hat is the
only system you use then learn them. I also use several other Unix, BSD
and Linux systems and do not feel the need to memorize Red Hat's quirks
when standard Unix syntax works.
