My site has for a short time an internet class C adress. We have a small (15 machines) domain-ring, and an equal number of others computers on an ethernet. Presently (sr10) all the machines communicate without problems with tcp ip. We have 2 different domains, and an apollo gateway. Now, we must renumber all the machines, with respect to our class C adress. My problem is : how can i use the same class C adress with a domain ring and a plain ethernet ? I am not a tcp/ip expert and the documentation did not seem to be very helful (at least to me !). Could somebody give me some hints ? Many thanks in advance, A.

Could somebody >give me some hints ? You have to have your domain ring be one network and the ethernet be another network Your apollo gateway can run /etc/routed to route between the two networks. These networks can be subnets, where you divide the host portion of your class C address into a network and host portion. This is done with the mask option to /etc/ifconfig. Alternatively you could get another class C address for the token ring. -- Dave Kerr (301) 765-4453 kerr%tron.UUCP@umbc3.UMBC.EDU from an Internet site kerr@tron.UUCP from a smart uucp mailer
