[mod.computers.apollo] TCP/IP Problems

northover@cascade.carleton.CDN.UUCP (03/21/87)

    Hi.  I have just installed TCP/IP on our Apollo ring and have come across
the following bizzare behavior.  From the gateway node, it is possible to access
external sites.  From any node on the ring, it is possible to access any other
node on the ring.  From a non-gateway node, it is NOT possible to access any external
sites.  The error message indicates a timeout.

    Has anybody else seen this?

Thanks in advance,

I also find that running routed on the other machines on the ethernet
will fix the problem.  Since routed is the program that reads the
gateways file, this makes some sense.

As for setting up the hosts table, the gateways table and other such
tables, I write the stuff in NIC format and use htable on it.  I find
that this is by far the easiest way.

Perhaps someone can explain to me why running routed on the other
machines on the ethernet is necessarry.  I was trying to get a microvax
to talk to the other machines on the network.  The microvax would not go
through any gateway (including the apollo gateway).  I assumed that
since only the gateway on the Apollos needs to run routed that only
gateways on the rest of the network need to run routed.  The microvax
was not a gateway machine and so was not running routed.

The only way I could get the microvax to go through gateways was to run
routed on the microvax.  Why must I run routed on the microvax, but not
on the apollos which don't gateway?
