 +====== Visualising data flow from RMDS02 station ======
  
 +The last station’s version allows a use of a remote visualising tool [[en:​freya|Freya]].
 +
 +
 +===== Direct connection to station =====
 +
 +
 +
 +==== An older way - using a jackd ====
 +
 +Stations, which use jack system for connecting the detection software, can be used with Freya software as well. It is only necessary to run a server on a station:
 +
 +  ../​jack-stdout/​jack-stdout -e float system:​capture_1 system:​capture_2 | ./x_fir_dec -b 128 48000 10500 24 3731_taps | ./​servestream -p 3731
 +
 +===== Connecting via a tunnel =====
 +
 +Connecting to a station via a tunnel is useful when there is no direct internet access to the station’s computer. This includes cases, when the station does not have a public IP address or the router setting by internet provider does not allow direct connection.
 +
 +The following command (when ran from a command line on a computer where you want to start [[en:​freya|Freya]]) opens a tunnel from the station to a computer from which it was run.
 +
 +  ssh -v -L 3731:​localhost:​3731 space.astro.cz ssh  -L 3731:​localhost:​3731 -N radio-HPHK.tunnel
 +  ​
 +<WRAP info>
 +In order for tunnel to function properly, there must be a functional logging from space.astro.cz to the station without using a password. To do this, you have to have a copied ssh key on the station - it can be done easily using ssh-copy-id. ​
