What does telnet require that ping does not?
A running telnet daemon on the destination host.
Right....
I know this is tangential, but this reminded me of something interesting
I noticed recently. I have 2 systems neither running the telnet
service. One is a RHELv4 system and the other a F16 system.
Trying to telnet to the RHELv4 system gets "Connection refused" while
trying to the F16 system gets "No route to host". Weird. Will have to
check into that a bit more when I have the chance.
I'd guess the firewall on the RHEL4 system isn't blocking the
connection, so the connection to port 23 is simply rejected, while the
F16 system's firewall is blocking it, so that system pretends like
it's not there.
-T.C.
Sorry, I should have stated that I have the firewall turned off. I set
SELINUX=disable in /etc/sysconfig/selinux.
