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? Michael Schmidt, CADLAB / FB 17, Uni-GH Paderborn, Bahnhofstr. 32, D-4790 Paderborn, West Germany Mail: schmidt@cadlab.UUCP or schmidt@cadlab.cadlab.de

During a recent subnet conversion there was real confusion about what the "proper" broadcast address should be. Some gateways were using 1's in the machine address and others 0's. Sun's ifconfig allows you to specify the broadcast address and defaults to machine address 0's. I don't know if that's your problem, but it's worth looking into. Terry Kovacs AT&T BL Murray Hill
