Doubtful. If it's taking 20 seconds for a prompt where it used to
take, say 5, then I would immediately suspect DNS -- assuming of course
that you're telneting from another net. If you're on the same segment,
then ...

This is so obscure, it's useless. Missing from where? Route tables?
NIC? DHCP server? DNS?

What's an UP BROADCAST? That means the net connection is UP, BROADCAST
is enabled.

Actually, ifconfig output -- all of it -- is what is needed here
together with route -n. If you want to obscure your IPs, use XXX.XXX
for the first two octets, eg. But _all_ of the netmask.

Could be you're forwarding DNS where you should not -- no way for me to
even guess without specific data/info/command output.

Why on earth did you even try this and what did you expect to gain?
The hardware "stirs" IRQ requests and it's not unusual to see 5 or 6
items on IRQ 11.

Since I don't know where you're telenting from or the layout of your
problem net or your IPs or what netmask you _should_ be using or
whether probnet is using static IPs or DHCP or what your default route
is/should be or -- well, you get the picture. Solving network problems
requires bright light, not midnight fog. Especially long distance.

Get back with the needed info and someone around here will likely get
you an answer.
