The MNJ does issue a report every day - people who run it
should read it. Had you done so, you would have noticed that we
changed the LUNs used by AIPS for tapes from 31-30+NTAPED to 128
through 129-NTAPED. This has the unfortunate affect of making older
and the current aips incompatible for remote tapes. Version NEW
(31DEC03) can talk to older versions of TPMON. You could bring the HP
installation up to date - in fact we do have a concept of a server
only aips installation for the MNJ at least. See the JENLAN entry in
$UPDUNIX/UPDCONFIG for an example. One needs only compile APLSUB and
APLGEN parts of INSTEP2 and then link
$AIPNOT/{TPMON,TVSERV,TEKSRV,MSGSRV) and XAS to let the HP even act as
an aips terminal.
