 ======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
+    Hostname kuiper.as.arizona.edu
+    User rts2obs
+    IdentityFile /Users/pnd/.ssh/rts2obs
+  # +
+  # rts2artn
+  # -
+  Host rts2artn
+    Hostname 10.30.1.24
+    User rts2obs
+    ForwardAgent yes
+    ProxyCommand ssh -X -Y rts2obs nc %h %p 2> /dev/null
+    IdentityFile /Users/pnd/.ssh/rts2obs
+  # +
+  # rts2pi
+  # -
+  Host rts2pi
+    Hostname 10.30.1.25
+    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:
+  http://localhost/5000
+  http://localhost/8080/dashboard
+  http://localhost/8080/js9
+  http://localhost/8080/
