The following does reflect that proxyarp is the answer to my
question but as the kernel is finishing the boot my 3/50 hangs.
It hangs after the following:
hostname: ruby
domainname: .cs.clemson.edu
root on ypmaster-gw:/export/root/ruby fstype nfs
swap on ypmaster-gw:/export/swap/ruby nfs size 16384K
dump on ypmaster-gw:/export/swap/ruby nfs
I am not sure what is supposed to happen next but would assume /etc/rc
is supposed to get started. Packets are still getting through to the
ypmaster-gw but nothing else happens. If you don;t have a theory on
whats wrong I know someone has to know what the next occurences in the
booting sequence is.
Here is a summary of my original question:
>Because of space limitations on ypserver below we need to boot
>a diskless Sun 3/50 off of ypmaster. The problem occurs because
>the 3/50 is located behind the ypserver. The 3/50 sends out rarp
>requests that get answered by the ypserver therefore it wants to
>boot off of the ypserver.

This is a summary of the answers I received.
Use proxyarp. The message from dlc@LANL.GOV best explains it.
