[daip] AIPS on MAC OSX

[Patrick P Murphy]

After conferring with my erstwhile sysadmin colleagues, I think this is
the easiest way to proceed.

It is.  However, here is a quick recipe for creating and populating the
aipsman group:

echo 'aipsman:*:9200:sbeaulieu,egreisen,pmurphy' | niload group .

Note the trailing dot; that's VERY important!

However, you should replace 9200 with a suitable number for group ID
(GID; use the command "nidump group . | less" to see what numbers are in
use).  You may want to check with your local admins to avoid a group ID
clash in case you ever network the machine.

You should also replace the account names appropriately; I added several
just to illustrate the syntax (which is identical to that of the usual
/etc/group file).

This refers to the "Netinfo" GUI based tool.  If you stick to using
nidump (passive) and niload (active) as shown above, there should not be
a problem.

Hope this helps.
