+ | ====== 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: | ||
+ | |||
+ | ssh user_name@station_computer_name.tunnel | ||
+ | |||
+ | <WRAP center round info 100%> | ||
+ | This guide anticipates that the station has a turned on and [[en: | ||
+ | |||
+ | wget http:// | ||
+ | chmod +x ./ | ||
+ | sudo ./ | ||
+ | </ | ||
+ | |||
+ | |||
+ | ===== 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 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/ | ||
+ | ./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:/ | ||
+ | |||
+ | ==== Services provided by server ==== | ||
+ | |||
+ | * Generating RMOB pictures and their upload on rmob.org. | ||
+ | * Assembling data from [[en: | ||
+ | * Running iPython scripts for processing data from data server. | ||
