I could use some help here. Another department has an Apollo
system that they've hooked up to the campus IP network. I'm
not in charge of it, but I'm supposed to be the TCP/IP "answer
person" on campus and have been giving them some help with it.
They've set it up so that it's running the Domain/IX BSD4.2
stuff. It looks like the latest version since they just
installed new TCP/IP software. Now everything seems to work
fine except there's something funny that I can see from my
side. Every 30 seconds, /etc/routed is supposed to send out
a RIP packet informing the local network about which routes it
knows about. It seems to be doing this OK but it also blasts
out around a dozen or so other packets at the same time. I can
see 'em using NETWATCH on a PC. They all originate from the RIP
port, but all except the last seem to be destined for some other
strange port; I assume the last is the valid RIP packet. All
these are indeed broadcast packets, by the way.
When I first noticed this, it seemed like the Apollo system was
sending out more like 30 or 40 of 'em. I noticed that they had
their system configured so that it knew all the gateways on the
ARPAnet that were derivable from hosts.txt (from what I can tell
from the documentation, Apollo never heard of EGP). Anyway, I
fixed this by just emptying out the files /sys/tcp/gateways and
/etc/gateways; this seemed to quiet the critter down, but there's
still the dozen (maybe fewer sometimes) packets or so.
I'm at a loss. Does anybody know what's going on? Is it a bug
in the port of routed? Is it supposed to be doing this? Is
there a way I can quiet this thing down? For now, I just have
a default route to the campus gateway, but I'd rather run routed
if it didn't babble so much.
