Marcus, thanks for the insight.

I suppose there isn't much to prevent me from running the OpenAFS 1.4.12
version of kaserver on sun4x_58 as well if the list elders figure it is
helpful.  I won't be able to run a sunx86_510 version of anything IBM
because such things don't exist.

I suppose I could also think of upgrading IBM AFS to 3.6 2.59 (Patch 15)
which is the last version to which I have access on sun4x_58 and which
should have a consistent handling of NetRestrict across all servers.

sunx86_510 on 128.214.58.174 and sun4x_58 on 128.214.88.114 are NTP
peers with each other as well as clients to the same time servers
elsewhere on the Uni network.  If you have insight as to why this
might be a failure, I'm all ears.  My gut feeling is that time sync
problems between the two don't exist.  I ran "xclock -digital -update 1"
for a while side by side and they're less than a second apart at worst
in a few minutes of doing this.

Explain "path issues".  The OpenAFS on sunx86_510 was built with
"--enable-transarc-paths".  /usr/afs/etc/KeyFile exists and is
identical on all hosts.
