I am trying to determine the best configuration for SUN Yellow Page master and slave servers in a multi-ethernet environment. I currently have a 2-ethernet LAN as follows: ethernet ethernet #1 #2 --- --- | | | | | | |-------| | |-- SUN "B"| <--YP Slave Server | | |_______| (O.S. 3.5) | |---------| | |-----| SUN "A" |------------| | |_________| | | YP Master and Gateway | (O.S. 4.0.1) Machine "A" has hostname "A" on ethernet #1 and hostname "A-gate" on ethernet #2. It is running O.S. 4.0.1 and "B" is running O.S. 3.5. My question relates to establishment of a third ethernet with another machine, call it "C" as the gateway between ethernet #2 and the new ethernet #3. A diagram of the new LAN, without machine "B" for the time being, is as follows: ethernet ethernet ethernet #1 #2 #3 ----- ----- ----- | | | | | | | |--------| | |--------| | |-----| SUN "A"|-------|-------| SUN "C"|------| | |________| | |________| | | YP Master and | Gateway and ??? | | Gateway | running | (O.S. 4.0.1) (Sys4-3.2) Machine "C" is chosen as the second gateway machine because it can accomodate a second ethernet controller and is a faster, larger memory machine, whereas "B" cannot accomodate a second ethernet connection and is not nearly as much machine as "C". Assuming that "A" remains the YP Master - Would it be advisable to either: (a) Make "C" the new YP Slave instead of the current "B". Is this advisable considering that "C" is running Sys4-3.2.?? (Whereas "B" is running O.S. 3.5). (b) Retain "B" as the YP Slave and not make "C" a YP Slave machine. If this is true -- where should "B" be located in the network?? (c) Use "B" and/or "C" as YP Slaves in some other configuration?? Any responses are appreciated. Leon Howorth, HHB Systems, 201-848-8000 ext. 243. UUCP: ...rutgers!pyrnj!hhb!leonh
