Connecting to CIBR servers

Note: connecting outside of JYU requires using VPN, e.g. Cisco

Connecting to CIBR Servers using NoMachine virtual desktop

  1. Install the NoMachine client from nomachine.com, if it has not yet been installed on your computer
  2. Click the connection you want to re-establish. If there are no suitable connections, you need to make a new one as follows:
  3. Choose “New connection”, and protocol NX.
  4. To host field, write the server name (cibr-srv1.psy.jyu.fi or cibr-srv2.psy.jyu.fi)
  5. For authentication, we are using JYU user name + password
  6. Fill in the remaining details, if any
  7. Double-click to log in to the server using your personal user name and password
  8. If you have connection problems, check first that the protocol is NX and the port is 4000. Confirm that you have the rights to access (i.e. user account for the server)
  9. Double-click on “Create new virtual desktop”. Conduct your work as if sitting next to the server computer!
  10. When you are finished, you have two options:
    1. if you are really entirely finished, log out by clicking your name in title bar and “Quit”. This will logout and close your session on the server, and it will  free the NoMachine license for the other users.
    2. if you are going to continue later from this point, you can just close the NoMachine window without logging out from the server. The session will remain available, and you can later re-connect from the same or another computer.

Write cibr-srv1.psy.jyu.fi  to “Find a user or a desktop” → Enter → YES

Connecting to CIBR server using Xming and Putty on Windows (example Matlab)

For this recipe to work, you need:
- Windows computer with access to CIBR server
- Putty installed
- Xming installed
In JYU computers Xming is available via the Software Center. If Putty is not already installed on your computer, you can freely download and use it on your computer without administrative rights.

After Xming and Putty are downloaded, set the following settings on them:

Xlaunch

Putty

To ease your future connections, first create a new “Saved session” by writing any name you want to “Saved Sessions” box and the server address to “Host name”. The server address can be either “cibr-srv1.psy.jyu.fi” or “cibr-srv2.psy.jyu.fi”. Port is 22 and connection type is SSH.

Opening Matlab with Putty
First run Xming. This will create a stylized X-icon in the lower right corner of the Windows taskbar which indicates that the X-windowing is now available.

Open SSH connection with Putty to CIBR-server by using the instructions above.
Next you will be asked for your JYU username and password.
Afterwards you will end up to a screen which looks like this:

Now by typing “Matlab” and pressing enter you should get the program up and running with a graphical user interface. Author of these instructions does not know how well this X-windowing method works with other programs found in the CIBR servers.

Install the NoMachine client from nomachine.com, if it has not yet been installed on your computer
Click the connection you want to re-establish. If there are no suitable connections, you need to make a new one as follows:
Choose “New connection”, and protocol NX.
To host field, write the server name (cibr-srv1.psy.jyu.fi or cibr-srv2.psy.jyu.fi)
For authentication, we use user name + password
Fill in the remaining details, if any
Double-click to log in to the server using your personal username and password
Double-click on new virtual desktop. Conduct your work as if you were sitting next to the server computer!
When you are finished for the day, you have two options:
if you are really entirely finished, log out by clicking your name in title bar and close NoMachine. This will close your session on the server and free the license for other users.
if you are going to continue later from this point or you have processes running on the server, you can just close the NoMachine window without logging out from the server. The session will remain open, and you can later re-connect from the same or another computer.

Connecting with SSH (Linux/Mac terminal)

SSH is natively installed on Linux and MacOS computers. All you need to do to get connected is opening a command terminal and writing:

ssh -Y <username>@cibr-srv1.psy.jyu.fi

where you naturally replace <username> with your 8-letter user name. Give your password when the system asks for it and you’re ready. The option -Y can be skipped if you don't need graphics.

Kärki 2nd floor analysis class

Kärki 2nd floor computer (analysis) room, Aa2xx

This room is reserved meant mainly for student work. The equipment available is:

- 6 Windows computers with internet access

  • Used by all psychology students and occasionally staff members
  • Use your personal JYU account to login
  • Some of the computers might have certain special programs installed, like BESA
  • NoMachine available

- 4 Linux computers with network

  • Used for accessing the CIBR servers
  • NoMachine available
  • Shared username and password

- 1 Stimulus computer with no internet access

  • A replicate of the MEG stimulus computer
  • Presentation (with license dongle) installed
  • Can be used to test your Presentation paradigms for MEG
  • Equipped with a self-made button box which electronically and logically works almost like the 4-button response pad in the MEG lab

MEG lab computers

MEG laboratory measurement room has five computers. One is for data acquisition (named Dacq), two for stimulus system (one Windows, one Linux based). One computer is a touch screen monitor/computer which works on Windows. This computer is normally only used for EEG preparation. But it can also be used for other subject preparations, for example HPI coil setups. However, for this might not be extremely straightforward. The fifth computer is situated in the back room and can be used for data pre-analysis. This computer has direct access to the data acquisition computer, but only to a certain folder. Therefore, if one wants to use the computer for data analysis, the data has to be saved to a correct place.

Dacq

  • Nowadays only common username and password are used. If you don't know them, maybe you don't need them then.
  • If you are measuring sensitive data to the computer, remember to transfer it to the CIBR server and then delete from the local computer after the transfer has been completed and secured.
  • Is used to control the Helium recycling scheduler.

Stim-pc

  • Common username and password.
  • Windows-based.
  • Normally used for Presentation-based stimulus.
  • No internet access.

Linux-stim

  • Common username and password.
  • Linux-based.
  • Normally used for Python- or Matlab-based stimulus.
  • No internet access.

Use the switch below the Stim-PC screen to switch the projector display and/or trigger source between Stim-PC and Linux-stim.

Subject preparation/digitization computer (touch screen)

  • Common username and password
