Remote Observing

Currently our remote observing still requires a user at the telescope. However, we are working on developing monitoring tools and making it easier to reach the remote observing goal.

Using An SSH Tunnel

The simplest way of accessing the telescope and observing websites is to use an SSH tunnel. All you need to do this is knowledge of the rts2obs password and/or your own ssh key. First, add some hosts to your ~/.ssh/config file. My private ssh key on my MacBook Air is stored in “/Users/pnd/.ssh/rts2obs” so edit that to suit your own key:

# +
# rts2obs
# -
Host rts2obs
  User rts2obs
  IdentityFile /Users/pnd/.ssh/rts2obs
# +
# rts2artn
# -
Host rts2artn
  User rts2obs
  ForwardAgent yes
  ProxyCommand ssh -X -Y rts2obs nc %h %p 2> /dev/null
  IdentityFile /Users/pnd/.ssh/rts2obs
# +
# rts2pi
# -
Host rts2pi
  User pi
  ForwardAgent yes
  ProxyCommand ssh -X -Y rts2obs nc %h %p 2> /dev/null
  IdentityFile /Users/pnd/.ssh/rts2obs

To check that this has worked, you should now be able to login to both those machines using the shorthand hostnames. Note that this might prompt for a password until you install your public key in the authorized_keys file on the remote machine:

% ssh -XY rts2obs
rts2obs@gerard:~$ exit
% ssh -XY rts2pi
pi@raspberrypi:~ $ exit

Add the following commands to a ~/.alias file:

alias rts2pi_tunnel="ssh -CL 5000:localhost:5000 rts2pi"
alias rts2artn_tunnel="ssh -CL 8080:localhost:80 rts2artn"
alias xrts2pi_tunnel="xterm -e ssh -CL 5000:localhost:5000 rts2pi &"
alias xrts2artn_tunnel="xterm -e ssh -CL 8080:localhost:80 rts2artn &"

When ready to remote eavesdrop, source the file:

% source ~/.alias

Now, either run the simple tunnel in a regular terminal or use the terminal start:

% xrts2pi_tunnel
% xrts2artn_tunnel

NB: you *must* wait until the tunnel is complete and you are logged into the remote machine.

Then–voila!–point your local browser to:
