I've just installed CAP here at Waterloo (it's terrific by the way - and
that Configure script is incredible) and I've run into a problem on our
main ethernet with the internet addresses we use.

We have a class B network, subnetted, with a netmask of 0xFFFFFE00
i.e. we use the last 9 bits for the host part.  One of our hosts is
129.97.128.24 and another is 129.97.129.21.  Now I have cap working
just fine on the host 129.97.128.24 i.e. where the last 8 bits is
equal to the actual host part because the 9th bit is 0.  I've run into
problems with the other host though.  atis seems to start up okay,
but aufs fails with the message "SrvrRegister for <hostname> Aufs
failed...".  I tried the atalk.local file with the node number as the
last 8 bits, and as the last 9 bits (i.e. 277), but both seemed to
result in the same failure.

Is there a way around this problem?  My guess might be that something
in the cap code is generating an address by taking the network part
and adding the node number to it, missing the high bit of the host part.
But I'm not quite sure where to start looking.  I didn't see anything
to indicate that the UNIX node numbering in atalk.local is a necessity
rather than a convention.  Thanks for any help you can give.
