after having obtained a class-b internet number assignment, i am building a subnetted network wherein i am using a subnet mask to create, obviously, subnets. my system consists of a number of sun sparcstations, partitioned into small networks, each network being SLIP'ed back to another sun or to a XYLOGICS annex IIe terminal server running SLIP. I am using U of Toronto SLIP 4.0 w/the sun-supplied mclput panic fix. since my subnet mask includes bits from the fourth octet, my networks don't all begin with a zero in the fourth octet. however, whenever i assign a subnet in which the fourth octet happens to be zero, things don't work correctly. i.e. whenever i assign a network number in /etc/networks in which the last octet is zero, e.g. test.net.edu nn.nn.nn.0 where nn are any valid integers, ... when i do this, and then do a netstat -r , the system shows the network number, not the network name ( e.g. test.net.edu ) as it should. also, the routing funtions ( including broadcasts of RIP packets ) just don't work right, and these zero-suffixed subnets don't get into other machines' routing tables. anybody know a good fix for this, or do we all simply have to throw away every sub-network number that ends with a zero octet. ( which amounts to 255 network numbers if you have subnet mask bits set from the fourth octet !!!! ) thanks in advance for your help. jpw univ of ill at chicago
