Subject: Re:  Subnet changes.
Status: RO

I've left two tar files in /usr/tmp/scooter.{1,2}.  The first
is the new routing daemon, which I suspect is substaintially
different than the one you're running.  The 2nd are the kernel
changes necessary for subrouting.  The changes here are few,
but rather than trying to send you diffs, I thought it might
be easier for you to have the whole file(s).  If you want
diffs to, please let me know.

You may also need a new /etc/ifconfig (I think this program was
called something slightly different in 2.9bsd), since there is
a new "local" flag for the subnet stuff.  The subnet and routing
changes are really independent of one another, as best as I
remember right now at least.  I know the new routing daemon is
needed for sure in our case on CGL, since the old one never
worked with point to point links and had countless number of
other bugs as well.  You can't go wrong (did I say that?) with
the new /etc/routed.  The subnet code simply allows sites that have
class A or class B networks to break these networks up into a
number of different nets locally, but still have sites outside the subnet
see network address as simple class A or class B networks.  Since
UCSF is a class C network, none of this really applies, although
since Berkeley is a class B network and the CGL <--> ARPAvax link
is also a class B subnet, I had to add the subnet changes to CGL.
I'm not sure you'll need these changes at SSU; install the new routed
first and see if that fixes your problem.  All network hosts at
UCSF should be running the new routed; since these are nearly all
vaxes the binary from cgl:/etc/routed can just be copied to the other
machines.  If you want to do this on MIS, it's fine by me.  You'll
need to be root so you can kill of the running routed before doing
the copy.  Let me know if you have any problems.
