I'm trying to set up a SLIP connection between my
VAXstation 4000/60 and a DECpc (Pentium-60). I've
connected a null modem cable between COM2 on the
DECpc and the 25-pin serial port on the VAXstation.
I believe the 25-pin serial port on the VAX is
/dev/tty02 - is this correct?
I've executed the following commands -
on the VAXstation:
slattach /dev/tty02
ifconfig sl0 192.168.1.1 192.168.1.2 up
and on the DECpc:
slattach /dev/tty01
ifconfig sl0 192.168.1.2 192.168.1.1 up
But alas, the machines still cannot ping each other -
from the DECpc:
# ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1): 56 data bytes
ping: sendto: No route to host
from the VAXstation:
# ping 192.168.1.2
PING 192.168.1.2 (192.168.1.2): 56 data bytes
^C
----192.168.1.2 PING Statistics----
3 packets transmitted, 0 packets received, 100.0% packet loss
In fact, they can't even ping the address of their own sl0
interfaces -
from the VAXstation:
# ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1): 56 data bytes
112 bytes from p133 (10.0.0.32): Destination Net Unreachable for icmp_seq=0
112 bytes from p133 (10.0.0.32): Destination Net Unreachable for icmp_seq=1
^C
----192.168.1.1 PING Statistics----
2 packets transmitted, 0 packets received, 100.0% packet loss
[same thing on the DECpc.]
The routing tables look correct -
on the VAXstation:
# netstat -rn
Internet:
Destination Gateway Flags Refs Use Mtu Interface

192.168.1.2 192.168.1.1 UGHS 0 4 1500 sl0
and on the DECpc:
# netstat -rn

192.168.1.1 192.168.1.2 UGHS 0 2 1500 sl0
I can't see anything wrong with the ifconfig output either -
VAXstaton:
# ifconfig -a

Am I missing something, or is SLIP broken in NetBSD 1.5?
