Depends on the telnet client. On unix boxes, "/usr/bin/telnet qube2 80"
will do what you want. On windows client, you'll need to find some dialog
that says "port number" and change it from 23 to 80

Not a good sign. I'm all for rebooting it and seeing what happens.

I'll have to be honest here and claim ignorance. I believe 'ping' handling
is a function of network stack, so if you can ping a machine (get a response),
then the hardware is okay enough for it to power on, boot up and load the
network stack. Also, that tells you there is a known route to the remote
machine (from the computer doing the pinging) and a known route (not always
the same way back!) from the remote computer back to yours.
The daemons (ftp, httpd, telnetd / sshd, etc.) are another matter - they're
more than just receiving and kicking off ICMP packets - there's protocols
to negotiate, handshakes to establish, etc.
Mind you, this is all from some classes I took (and slept through) over a
decade ago, so I maybe completely out to lunch. If so, perhaps someone
will correct me.
Who am I kidding? Given the pedantic nature of some of the list participants,
I'm *sure* someone will correct me. =)
