   For large environments such as ours, DADEVS.LIST has the
requirement for optional disks (those with a minus in col 1) that the
path to them contains the host name, e.g. PRIMATE for my machine and
note the upper case.  I may well set up in a small environment
    /usr/local/yosi/aips/DATA/PRIMATE_1
    /usr/local/yosi/aips/DATA/PRIMATE_2
as ln -s links to /data1/jg168/AIPS and /data2/jg168/AIPS and then
list the /usr/local/yosi/aips/DATA/PRIMATE_n in DADEVS.LIST and NETSP.
Alternatively, and this has no down side in a 1-computer environment,
make the disk areas "required" by replaing the - sign with a + sign.
Then disk areas will be found (assuming they have a writable SPACE
file in them).

      The files are in the path either in $SYSLOCAL or $SYSUNIX - the
latter in this case.

 but when I try to run AIPS I get

This is a separate issue - from our AIPS Manager FAQ 
at http://www.aips.nrao.edu/aipsmgr/

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.

Note that this FAQ also covers issues related to XWindows depth and
maximum shared memory that may also affect you.

You can test for those before doing the services by saying

   aips tv=local 

which uses unix sockets rather than Inet ones.  Again no down side in
a one-machine environment.
