rawtransferd

Rawtransferd is a daemon server running in background on the server borg. It is responsible for monitoring the directory on the K2 computer where the frames are saved by default by Leginon, and to transfer them to borg. Each time a new stack of frames is found, the program interrogates the Leginon database, and if the stack is linked to a session, then the file is renamed according to that session and transferred.

ssh borg

You can verify the activity of the program by inspecting the file

/var/log/rawtransferlog

after logging in to the server borg.

If you observe that during an acquisition the frames are not removed from the K2 computer, then you can login to borg and check the status of the program. Here below are the basic commands to control the program.

sudo service rawtrasferd status

sudo service rawtrasferd stop

sudo service rawtrasferd start

sudo service rawtrasferd restart

The setup of the program is done through a configuration file that is automatically loaded each time the program is restarted. The configuration is by default

/etc/myami/rawtransferd.cnf

If you need to change the setup, modify the configuration file and restart the program.
