C.3.5 IP H OSTS ON E THERNET C ANNOT T ELNET TO THE R OUTER
There are 2 possible causes:
• The Ethernet cable is not fully functional.
• The Router may be configured with the wrong IP address.
Possible cause #1—The Ethernet cable is not fully functional. The cable may not be connected correctly or
it may be damaged.
Suggestions—Check the appropriate Ethernet cable to ensure that it is seated correctly.
Issue the trace eth0 command on the Router to determine if the Router is receiving the telnet traffic.
The trace command is used to display incoming and outgoing traffic on a given interface.
Watch the network activity LEDs while trying to access the Router over the Ethernet.
If possible, try attaching the Ethernet cable to another node on the same network that supports
TCP/IP and telnet into it, to verify whether the cable is good.
If possible, use a network analyzer to determine if packets are being sent to the Router.
Possible cause #2—The Router may be configured with the wrong IP address.
Suggestions—If you have a machine available that supports DOS formatted disks, use an editor to read the
config.net file on the boot diskette (or use the ifconfig command to display the IP address) and verify that
the correct IP address is found in the file.
Before editing the boot diskette, uncompress it by entering:
a: \stacker a: < RETURN>
