You can use ssh, RDP and x2go to connect to the container. Usernames and passwords will be provided on paper slips in Quantum for all the participants in the course.

X2go is a faster, safer and better method to connect. Please use XFCE as the session type, here are typical settings (of course use your user account):

For more information, see: https://wiki.x2go.org/doku.php/doc:installation:x2goclient

With RDP, you get a full desktop instead of one terminal like in ssh connection. The client software is installed by default in Windows (with some recent exceptions?) and several are available in linux distributions (remmina, rdesktop, xfreerdp in freerdp2-x11). With Mac, you have to install the free client from the standard Apple software sources (Microsoft Remote Desktop).

If you terminate the connection without logging out, you will get the same session in the subsequent login. The session will not of course survive reboots, so save your data before leaving!

We will use the standard RDP port in the connection, so do not use a port number (42004 in some of the images, you should leave it blank).

Use case 2 in the following link: Use Remote Desktop to connect to the PC you set up

https://support.microsoft.com/en-us/help/4028379/windows-10-how-to-use-remote-desktop

In case of ssh, the command is

 ssh -Y USER@tube.utu.fi
 

on Linux.

Note: you have to do the following every time you open up a new window!

1) To activate iraf related software, in your current terminal, write the command iraf27 and cd ~/iraf

1b) If this is the first time you use IRAF, write the command mkiraf in your iraf27 terminal in the iraf folder. It will ask about the terminal type, write xgterm and this will create a login.cl file to the iraf folder.

2) In the iraf folder with the iraf27 terminal write the command xgterm &

3) Write the command cl to your newly opened xgterm terminal to start iraf.

4) To open ds9 write the command ds9 & in the iraf27 terminal.

Note, that you have to process your data within your iraf folder or any subfolder you create there.

To activate starlink (https://www.eaobservatory.org/~s.graves/WWW/) software, e.g. gaia, write the command starlink and then gaia

When you finish your session on the course container, you can exit just by killing the remote desktop client window. You will return to the same desktop when you log in again. You can log out from the session via Applications → Log Out → Log Out.

Sometimes when you return to x2go session especially if the session is still running in another client, the client asks whether to suspend or terminate the session. Usually you want to suspend and then resume. terminate will kill the running session and start a new.
