- I'm new at this and simply want to network a PC to UNIX over a modem.
- The quality of the NOS documentation caught my attention and I started
- experimenting. Two days down the drain, and I can't get it to work.
- Anyone help? Is may approach reasonable? Are all SLIPs compatible?
-
- Configuration:
- UNIX: A Motorola 1167 running R3V7.0 UNIX with the SLIP
- provided by their NSE package.
-
- PC: 386 PC with the hardware configured in NOS by:
- attach asy 0x3f8 4 slip sl0 1024 576 9600
-
- I debugged with a direct line between the PC and 1167. A "ping" from
- PC to UNIX and nothing happens. A "ping" from UNIX to the PC causes the
- following repetitive messages on the PC:
- sl0 recv:
- serial line IP: len 26
- IP: bad header
-
- sl0 recv:
- serial line VJ compressed TCP: len 8
- changes: 0x9e TCP checksum 0x7ef8 PUSH
- delta window: 0x7e delta ack: 0x60 delta seq: 0xe increment id
-
- sl0 recv:
- serial line VJ compress TCP: len 117
- changes 0x80 TCP checksum: 0x0066
- increment id
-
- An ipstat on the PC:
- ipInReceives: 10 ipInHdrErrors: 10 ...
-
- ifstat on the PC:
- ... link encap SLIP
- flags 0 netmask 0 broadcast 0.0.0.0
- sent ip 0 tot 0
- recv ip 19 tot 19
-
- asystat on the PC:
- sl0: [trigger 0xc0] 9600 bps
- RX: 468 int, 486 chr, 0 hw over, 1 hw hi, 0 sw over, 103 sw hi
- TX: 0 int, 0 chr 0 q 0MS int 0 THRE TO

- Thanks in advance!
