In the course, you will be working on a Linux server. You can connect to this server via ssh, using the same username and password as for AIS2. In the computer classroom at the faculty, we recommend working from Linux.
Connection through ssh
If connecting from a Linux computer, open a console (command-line window) and run:
ssh your_username@vyuka.compbio.fmph.uniba.sk -XC
The server will prompt you for password, but it will not display anything while you type. Just type your password and press Enter.
If connecting from a Windows 10 computer, open command-line window in Ubuntu subsystem for Windows or Powershell and run
ssh your_username@vyuka.compbio.fmph.uniba.sk
When prompted, type your password and press Enter, as for Linux. See also more detailed instructions here [1]
For Windows, this command allows text-only connection, which is sufficient for most of the course. To support for graphics applications, follow instructions in the next section.
Installation of X server on Windows
This is not needed for Linux, just use -XC option in ssh.
To use applications with GUIs, you need to tunnel X-server commands from the server to your local machine (this is accomplished by your ssh client), and you need a program that can interpret these commands on you local machine (this is called X server).
- Install putty client which you will use instead of ssh.
- Install X server, such as xming
- Make sure that X server is running (you should have "X" icon in your app control bar)
- Run putty, connect using ssh connection type and in your settings choose Connection->SSH->X11 and check "Enable X11 forwarding" box
- Login to the vyuka.compbio.fmph.uniba.sk server in putty
- echo $DISPLAY command on the server should show a non-empty string (e.g. localhost:11.0)
- Try running xeyes &: this simple testing application should display a pair of eyes tracking your mouse cursor
Copying files to/from the server via scp
- You can copy files using scp command on the command line, both in Windows and Linux
- Alternatively use the graphical WinSCP program for Windows
- On Linux, you can mount the filesystem from the server as a directory on your machine and then work with it as with local folders, using both command-line and graphical file managers.
