 +====== Remote maintenance of stations ======
 +
 +To access the maintenance interface, access data to space.astro.cz server are necessary. Most of the stations are then accessible and maintainable from the server.
 +
 +The procedure is as follows:
 +
 +  ssh observatory_name@space.astro.cz
 +
 +If the authentication with the public key proceeds without problems, you will be connected to space.astro.cz server. There you can view your station data or delete any unnecessary data.  ​
 +
 +To connect to your [[en:​stations|station]],​ use the following command: ​
 +
 +  ssh user_name@station_computer_name.tunnel
 +
 +<WRAP center round info 100%>
 +This guide anticipates that the station has a turned on and  [[en:​odroid-u3#​vzdaleny_pristup_na_stanici|configured reverse ssh tunnel]] with parameters in the config file /​etc/​ssh_config on space.astro.cz server.
 +
 +  wget http://​space.astro.cz/​bolidozor/​support/​scripts/​setup_reverse_tunnel.sh
 +  chmod +x ./​setup_reverse_tunnel.sh
 +  sudo ./​setup_reverse_tunnel.sh ​
 +</​WRAP>​
 +
 +
 +===== Getting an access space.astro.cz =====
 +
 +The best option is to use a public key to log in. In such case, the space.astro.cz server will not require any password. ​
 +The key pair has to be generated on the computer that you will use to get access to space.astro.cz. You can do it using a command line and running the ssh-keygen utility:
 +
 +  ssh-keygen
 +
 +The utility will ask several questions, leave them empty. Only confirm the choice by pressing enter. ​
 +Then it generates two files id_rsa.pub and id_rsa. id_rsa.pub file contains a public key, which has to be transferred to space.astro.cz server.
 +That can be done either from the station, by copying the content of the file into the file ///​~/​.ssh/​authorized_keys//​ that already exists on space.astro.cz serve (in the home directory of the observatory) or by setting a password. The password can be set during connecting to space.astro.cz (station connects to server automatically,​ using authentication key). To connect to space.astro.cz from station run:
 +
 +
 +  ssh observatory_name@space.astro.cz
 +  ​
 +Using a command line on space.astro.cz server, set the password with passwd.
 +
 +===== The most common operations on a station =====
 +
 +==== Stopping and starting detection software ====
 +
 +  cd repos/​station-supervisor/​
 +  ./stop.sh
 +  ./start.sh
 +  ​
 +==== Restarting a station ====
 +
 +  sudo reboot ​
 +  ​
 +==== Turning the station off ====
 +
 +  sudo poweroff
 +
 +
 +==== Loading a test RAW record from the receiver ====
 +
 +  nc localhost 3701 | sox -t f32 -c 2 -r 96000 - test.wav trim 0 30
 +
 +This command creates a 30s long WAV record of complex samples from receiver on a running station. For further processing, it is advantageous to copy it on space.astro.cz to the station’s account.
 +
 +  scp test.wav ZVOLENEVES@space.astro.cz:/​storage/​bolidozor/​ZVOLENEVES/​.
 +
 +==== Services provided by server ====
 +
 +  * Generating RMOB pictures and their upload on rmob.org.
 +  * Assembling data from [[en:​meteor-observer|Meteor Observer]] mobile application.
 +  * Running iPython scripts for processing data from data server.
