Does anyone have any suggestions on how to debug this problem with the
lp TCP/IP driver on FreeBSD 2.0?
I have a laplink cable between two parallel ports. Laplink works
fine. BSD detects:
Aug 17 00:17:14 osprey kernel: lpt0 at 0x3bc-0x3c3 irq 7 on isa
Aug 17 00:17:14 osprey kernel: lpt0: Interrupt-driven port
Aug 17 00:17:14 osprey kernel: lp0: TCP/IP capable interface
When I try to ping over lp0 the *other* system gets the error:
lp0: Too many errors, Going off-line.
netstat -i returns
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
lp0 1500 <Link> 0 101 1 24 0
lp0 1500 lp-net 10.0.0.1 0 101 1 24 0
lo0 65532 <Link> 1553 0 1553 0 0
lo0 65532 local-net localhost.0.0.1 1553 0 1553 0 0
the other side indicates that it got 1 input packet.
Since tcpdump isn't supported by the lp driver, I am at loss on how to
proceed. Any ideas?
Thanks,
Mark <markd@grizzly.com>
