           You should never run as root while dealing with AIPS -
other than when installing certain system services.  Most of the
problems below come from files and directories owned by root and
inaccessible to nectaria.  Probably the quickest way to fix this is to
log in a root - having determined your group id - and do

    cd $AIPS_ROOT
    chgrp -rf <your_gid> *
    chown -rf nectaria *

Problems with the TV, message, TEK and tape servers

The instructions to change your /etc/services file are often
overlooked. The Inet versions of XAS with its TVSERV lock daemon,
MSGSRV, and TEKSRV all require that predictable node numbers be
reserved for them. The remote tape services also require these and do
not offer a UNIX (non-network socket) option. In both cases, if you
need to communicate between two computers (or more), the following
must be installed in your /etc/services (or YP services):

sssin           5000/tcp        SSSIN      # AIPS TV server
ssslock         5002/tcp        SSSLOCK    # AIPS TV Lock
msgserv         5008/tcp        MSGSERV    # AIPS Message Server
tekserv         5009/tcp        TEKSERV    # AIPS TekServer
aipsmt0         5010/tcp        AIPSMT0    # AIPS remote FITS disk access
aipsmt1         5011/tcp        AIPSMT1    # AIPS remote tape 1
aipsmt2         5012/tcp        AIPSMT2    # AIPS remote tape 2
aipsmt3         5013/tcp        AIPSMT3
aipsmt4         5014/tcp        AIPSMT4
aipsmt5         5015/tcp        AIPSMT5
aipsmt6         5016/tcp        AIPSMT6
aipsmt7         5017/tcp        AIPSMT7

You do not need to install all the tape services unless you have a
large number of tape devices on some computer.

The above you must do as root.

    I build a 
       source $AIPS_ROOT.LOGIN.CSH
or
       . $AIPS_ROOT/LOGIN.SH
into my login.  Then you only need say aips.

   This is a lot of "tapes" - do you really have 7 magnetic tape
devices (DATs and Exabytes) on your computer?  Note that floppy, CDRW,
and DVD are not supported by aips as sequential devices - they are
really disks and might work as such in AIPS although I doubt it.

        LOCALHOST is usually used for laptops - again raising the
question about magnetic tape devices.  But I worry that you did not
use it right.  Go to $AIPS_ROOT and look at LOGIN.SH and LOGIN.CSH.
Do they say LAPTOP is "YES"?  They should.

presumably owned by root not you

root not you

   This looks good - it is usually a proplem so this is excellent.

   The difference in case above (localhost vs LOCALHOST) suggests that
LAPTOP is not set YES in the LOGIN files and causes some confusion
here.

The remote tape jobs require network services in /etc/services but
only for those real tapes (and aipsmt0 for pseudo-tape disk) - You
told it 12 devices so there are 13 such errors.

      We (aips itself) may have an error here.  We have not worked
properly for > 9 tapes although we have just changed thing to try to
function properly.

You do not own the data directories and have no write permission so
cannot make catalogs and data files etc.

      If you have no magnetic tape devices then
$AIPS_ROOT/DA00/TPDEVS.LIST should be empty.  All AIPS data
read/writing tasks (FITLD, FITTP, FILLM etc) can read data from disk
as well as tape.

        It is not the tape errors that give you trouble - it is the
fact that you have no permission to write on the data directories.

      Root does have the permission to run but it is not a good idea -
root can do anything so a program error could erase your system disk.
The absence of the /etc/services causes the other errors.

Better an excess of information than a lack of info.

Perhaps this will help.
