- I have a potential problem with NIS in the presence of subnets. Advice would
- be appreciated.
-
- If a NIS client broadcasts to the subnet broadcast address (e.g. 130.159.248.255
- in the case of 24 bit subnets), a router will not propogate the broadcast onto
- other subnets on the LAN and hence the client won't be able to bind to a NIS
- server unless a server is on the same subnet. If however the NIS client
- broadcasts to the class B broadcast address (130.159.255.255) even when using
- an 24 bit subnet mask, the router can be configured to forward all subnet
- broadcasts and there is no problem.
-
- Which way does NIS do it?
