Re: SUN and Subnets

Berkeley has been using Suns on subnetted networks and (sigh) as gateways
for nearly two years. We added subnet support before we even had source
code by substituting 1 kernel source file and 2 header files, plus
ifconfig and routed. Unfortunately, several Sun changes have made this
harder to support, and the subnet scheme used is the old Berkeley scheme
which supports only 8-bit subnet fields with the high bit set. I have
been told by Sun systems people that subnet support will be in the 4.0
release, but that's not as helpful as I would like. I have been tempted
to figure out how to package and distribute subnet support for Suns,
but haven't taken the time to do so. Perhaps I could convince someone
else working with Suns at Berkeley to package things up if a few sites
could test it.
