Sorry to trouble you again with more plip problems. I am trying all
your suggestions and they are great. Just a few more and I am sure
this will work. Thanks for the help. I would have never thought of
turning of the arp. Unfortunately that has not solved the problem. I
have enclosed a sample output from both nimbus and cirrus of
/sbin/route and /sbin/ifconfig. I hope that someone can make sense of
it. I am at a loss. What do I try next? I have a multi-meter if it
makes sense to check parallel pins for output. (which ones?) I
bought a cable called Belkin Components Interlink/Laplink Parallel
DB25 Male/Male for DOS 6.0 so my soldering is no longer suspect. I
have made sure both kernels are being run without parallel printer
support configured in and both boot sequences show the plip interface.
I have also tried removing lpd to ensure that there is no contention
over the interface. I am running all conceivable daemons (as you can
see, both machines run the same daemons) so there should be network
help around for any program that needs it. I have tried pinging from
both machines and I have tried pinging both at the same time. No one
seems to find the other one. I often have to add the route to the
other computer back to the route table because it gets dropped. I
have also added default gw other.host to the route to help ensure the
packets get through (this has helped me on the real Internet with
routing problems I have never been able to track down).
One suggestion read:

Go a bit slower here, how do I check to ensure the port is free? I
only have a disk drive in the machine (not even a graphics card is
plugged in, I am using the built in vga port on the back. It is an old
machine) I have the cable plugged into the parallel port that came
with the machine. I have done nothing special to the machine besides
put linux on the disk.
