Hi stuart,
First step, try telnet 127.0.0.1 from your redhat box,
Check also netstat -a | grep telnet to see if *.telnet is in LISTEN state.
Did you restart xinetd after changing telnet to disable no ?
If netstat is Ok and telnet 127.. also then the trouble is in autorization from the network to access to your server.

hi,

Its probably your default redhat firewall
settings.

Do the following :

ipchains -F
ipchains -X

and try to telnet now ?
Does it work ?

to disable the firewall do permanently :

chkconfig --del ipchains

hope this helps

Hi Stuart,

did you think about your /etc/securetty file? If you simply rename it telnet should work:

mv /etc/securetty /etc/securetty.save

Allways stay on your bright side of life!

Hi stuart,

it seems, for benoit's question, that you don't have the telnet daemon running.

If you try that you'd get something like this:

[root@zeus /etc]# netstat -a | grep telnet
tcp 0 0 *:telnet *:* LISTEN

into inetd.conf you'd also have a line like this:
telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd

if is in the inetd.conf file it will be loaded automagicaly.

Hi Stuart,

Telnet has both a client and a server.
Make sure you have the server installed, the package name is telnet-server-.
If it is installed, go to /etc/xinetd.d and look at the telnet file:
make sure that the disable field is set to no.
If it was "yes" change it to no save the file and restart xinetd (# service xinetd restart).
HTH.
