[comp.protocols.appletalk] CAP/KIP and dynamic address assignment

mcgowan@ur-tut (Craig McGowan) (03/28/88)

Our Kinetics box reboots itself at least once a week.  When it does, it usually
comes back with a different appletalk address (our atalk.local has it set at
220).  When it doesn't have the right appletalk number, CAP services disappear.

My first instinct is to think that CAP should be able to find AppleTalk gateways
dynamically (or at least by querying their IP address).  Is there something I 
can do to work around this problem?

The Kinetics box has at least two AppleTalk addresses (three if
EtherTalk is configured in).  The first is on the LocalTalk interface.
This address should not be used because part of it (the node number)
is dynamic.

The second, is on the UDP/EtherNet interface.  This is a static
address and is the one that should be used in your atalk.local.  [The
node is always the last byte of the IP address on UDP based AppleTalk
addresses].

	Really?  That's amazing.  We've had a kbox for about 9 months now.
Except for a few horrible weeks in the beginning when we had a lemon power
supply, I can't remember a single time it has crashed (well, we had to reboot
it after a power failure once, but that hardly counts).

	I suspect your box has the "bad power supply filter capacitor" problem
which has apparantly been popping up on some kboxes.  There was a recall
letter that went out a few months ago.  Call Kinetics; they will either fix it
at their factory for free or send you the parts and instructions to do it
yourself if you prefer (from what I saw of the procedure, it's a 15-minute job
for somebody who knows how to solder).

Thanks to Charlie and Roy for responding.  Charlie's remarks prompted me to 
re-examine our atalk.local file.  The problem was that we had the AppleTalk
side of the kinetics box configured as the gateway address, rather than the
ethernet side.  Everything works fine in this configuration until the K-box
reboots and chooses a number that is different than what is in atalk.local
file.
