[comp.protocols.tcp-ip.ibmpc] KA9Q SLIP w/Sun3 only allows sessions with that host.

ron@vsedev.VSE.COM (Ron Flax) (01/21/88)

I have successfully connected a PC/AT Clone running the KA9Q package
on Xenix 2.2 to a Sun3/160 over a 2400 baud modem connection using
SLIP.  However, I can only establish sessions in either direction
between those two hosts, none of the other ethernet hosts connected to
the sun are accessible directly from the PC.

The addresses are as follows:
	
89.0.0.2	vsedev	(System 5 UNIX machine Excelan HW/SW)
89.0.0.3	vsepca	(Xenix machine Excelan HW/SW)
89.0.0.9	vsesun	(Sun3/160 internal ethernet, SLIP)
89.0.0.10	softdev (Remote Xenix machine running KA9Q SLIP)

There are more hosts but this is enough of a sampling to describe the
problem.

Like I mentioned... I can only start up a telnet/ftp session from the
vsesun to softdev, or vice-versa.  But when I attempt to start a
session say from softdev to vsedev, no dice!

I have tried many routing table combinations on both hosts, but have
been unable to overcome this problem.  Here's what the Sun's routing
tables look like now:

Routing tables
Destination     Gateway         Flags    Refcnt Use        Interface
softdev.vse.com softdev.vse.com UH       0      67         sl0
softdev.vse.com localhost       UH       0      676        sl0
89.0.0          vsesun.vse.com  U        4      9191       ie0
loopback        localhost       U        10     6114       lo0

And softdev's routing is by default sending all packets to sl0, which
is a point-to-point link to vsesun.  I have tried routing to say
vsedev via sl0 through vsesun with a metric of 1, but that failed as
well.

Help!  What am I doing wrong, or just plain not doing?
