This is very odd. AIPS expects RW privilege on the files and, around
here, is basically working across NFS all the time. The RW is provided
by having the files owned by the aips group and having all aips users
have the aips group as one of the secondary groups.
Because NFS has some problems with file locking, we do recommend that
the $DA00 files actually reside on the computer that is executing aips
although here we do that via soft links from the central file server.
Our systems expert appears to be out at the moment - perhaps he will
have some suggestion.
