Sender: questions-owner@freebsd.org Precedence: bulk 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 0 101 1 24 0 lp0 1500 lp-net 10.0.0.1 0 101 1 24 0 lo0 65532 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
