Hello,
I am inexpressably grateful to those who have taken the time to develop
these products and give their valuable time to helping ignorami like
myself.
I have followed the instructions to the best of my abilities to setup a
serial modem following section 2 of the user's guide. I want it to
operate on demand.
When PPP starts it announces that it "Cannot determine ethernet address
for proxy ARP" and never even starts to dial.
Please help me fix this.
I modified the base setup by adding a "-v" to /etc/init.d/networking and
"debug" to /etc/ppp/options, but I don't see any more messages in
/var/log/syslog. when doing "pon" or "poff".
My pings from the internal workstation aren't working either as
described below, but I think that it is a routing problem with the
workstation and I want to solve this first.
Please let me know if more info would be helpful.
Thanks to all for your attention,
Keith

Ping:
192.168.1.254->192.168.1.1 nothing appears onscreen until ctrl-c pressed,
then all failures reported. BOTH LEDs on hub flicker periodically.
Classic type 1 failure
192.168.1.1->192.168.1.254 repeats "Destination host unreachable" and only
the LED for 192.168.1.1 flickers.
exact wording not listed, but might be a type 2 failure.
