After installing Class B Internet numbers with a subnet mask of
255.255.254.0 we encountered problems with routing. Perhaps
somebody out there can give us a hint.
Machines:
SUN 3 SunOS 4.0.1, SunOS 3.5
Apollo 3000/3500 AEGIS 9.7 (Networking version 3.2)
Nixdorf Targon/35 (Pyramid) TOS 3.3.03
I don't know, whether the Targon OS No. is the same, Pyramid
called ist. But I really would like to know that.
Network:
Apollo token ring, gateway Apollo on an Ethernet with Sun's and
Targon/35's, one of them has a SLIP connection to another SUN.
Situation:
Targons and Apollos get the routing tables of the Apollo. Fine.
Sun don't get the routing tables. Bad. Routed gets a response to
its request, but after 3 minutes, all is dead again. So
apparently the Sun don't get the broadcasts of the Apollo.
The Targon with the SLIP connection broadcasts over the SLIP. OK.
But on the ethernet, nothing is heard by all the other machines.
What is going on here? Any idea?

OK. >But on the ethernet, nothing is heard by all the other machines. > We had a similar problem with `rwhod' until we changed our broadcast-address : ( from /etc/rc.local : ) # TODO: Define any machine host and network names here, # then check the "ifconfig" commands. ENET0=$HOST # ENET1=${HOST}-alt BROAD0=89.00.00.00 # BROAD1=altnet-broad NETMASK0=0xff000000 # NETMASK1=0xffffff00 We don't use the routed, and we never tested it, but try exchanging '00's and 'ff's in your broadcast-addresses. Also the ".254." in your subnet-address looks a bit strange to me. ^ Stefan Petri <petri@tubsibr.UUCP> Technische Universitaet Braunschweig, Institut fuer Betriebssysteme und Rechnerverbund, 3300 Braunschweig, W.

Perhaps >somebody out there can give us a hint. Solved it (in a way): I gave all "ifconfig"'s a "broadcast <sub net address>" and all is working fine now.
