[daip] [Fwd: aips problem ...]

[Amy Mioduszewski]

Hi Mike,

O.K., our Mac expert said you need to generate ssh keys on both your 
computers and put the keys in the authorized_key2 file on the other 
computer.  I.e., generate the key on Jansky and put it in the 
authorized_key2 file on Hollis and vice versa.  I have also noticed that 
there is a entry about this with more details on the AIPS Manager's FAQ. 
   Go to http://www.aoc.nrao.edu/aips/aipsmgr and scroll down to "My 
machine keeps asking for passwords".

About your laptop, since it gets different ip addresses it is better if 
you force the name of your laptop to be LOCALHOST for AIPS purposes.  So 
add a line to your HOST.LIST which says something like:
-  LOCALHOST  MAC   MYLAPTOP     NONE Hollis

Cheers,

Amy

Dear Amy:

My notebook gets reassigned IP addresses every time that I log in.  In
what follows, I have used the notebook to log onto my account 'hollis'
on computer 'jansky' at work from home.  I have used the ssh command

ssh -X hollis at jansky.gsfc.nasa.gov

and then executed aips. Here is the output from that session:

[JANSKY:~/Desktop] hollis%
[JANSKY:~/Desktop] hollis% xclock &
[1] 1958
[JANSKY:~/Desktop] hollis% Xlib:  extension "RENDER" missing on
display "localhost:10.0".

You have a choice of 2 printers.  These are:

     No. [ type  ] Description
-------------------------------------------------------------
      1. [     PS] (no description supplied by installer)
      2. [     PS] (no description supplied by installer)
-------------------------------------------------------------

START_AIPS: Enter your choice, or the word QUIT [default is 1]:
START_AIPS: Your initial AIPS printer is the (no description supplied
by installer)
START_AIPS:  - system name
phaser8400dx_on_128.183.35.153|phaser8400dx_on_128.183.35.153, AIPS
type PS

START_AIPS: User data area assignments:
   (Using global default file
/Users/remijan/Desktop/AIPS/DA00/DADEVS.LIST for DADEVS.PL)
    Disk 1 (1) is
/Users/remijan/Desktop/AIPS/B/Users/remijan/DATA/JANSKY_1
    Disk 2 (2) is
/Users/remijan/Desktop/AIPS/B/Users/remijan/Desktop/AIPS/DATA/JANSKY_1

Tape assignments:
    Tape 1 is REMOTE
    Tape 2 is REMOTE

START_AIPS: I am GUESSING you are at a workstation called hollis
START_AIPS: Checking if hollis is reachable via ssh...
hollis at hollis's password:

------------------------------------------------------------
That's the end of it -- the reason of the GUESS is that the IP address
that was assigned to the notebook did, in fact, have a computer known
as 'hollis' using that particular IP address.  Confusing, huh?
