Q: I have a linux box with a netgear card (DEC Tulip chip, 21*40 based ether
card) that works for outbound traffic (telnets from the machine). However,
inbound traffic (telnets to the machine) sometimes work, sometime don't
and at times hangs minutes after making the connection. What is wrong?

A: Check the RX dropped packets -- "ifconfig <interface>". If it shows a large
number of packets dropped vs. total number of packets, then there is a
good chance that the card has not auto-selected correctly. This was the
case with one of the machines that was connected to a 10Mbps, half-duplex
box. If using modules, add the following line to the /etc/conf.modules
files:

options tulip options=9

You can then either stop and restart the network or reboot the machine.
