== Starting SiTech software ==
''''N.B. These instructions have been updated in Feb 2023 - changes include the switch from 1ms1 to lesedis2 and setting . To start up Lesedi you must also follow the next section to set up the autoguider for Mookodi.''''
These steps involve opening multiple terminals. It is much more manageable to open multiple tabs in the same terminal, than to have many terminal windows to switch between. To do this, open one new terminal, then press '''CTRL-SHIFT-T''' in that window each time the instructions say to open a new terminal.
1. Open Remmina Remote Desktop Client, select "VNC" from the dropdown menu and double click on ioserver1 from the list of servers. Enter the password and the ioserver1 desktop will be displayed on the screen.
2. Look for an existing terminal on ioserver1, else open a new one, and log in to lesedis2(we'll call this terminal #1):
ssh -Y observer@lesedis2.suth.saao.ac.za (you shouldn't need the full path from inside the network, just observer@lesedis2)
7. '''Important''': every time the SiTech software is restarted, you also need to restart Lesedi's web server and backend.
* In a new terminal tab (terminal #2 - press CTRL-SHIFT-T in the terminalto open a new tab):
ssh observer@lesedis2.suth.saao.ac.za
sudo systemctl restart lesedi-web
exit ''(to leave the ssh session)''
exit ''(to close the terminal#2)''
8. If you ever need to restart either ServoSCommunicator or SiTechExe, you will first need to close all the other subsystem GUIs, and reopen them in the order above (or just run the start-up script).
