Connection through ssh

You can use ssh client available in Windows 10. On command line use: 

ssh <username>@vyuka.compbio.fmph.uniba.sk

However, if you want more configurable client with a capability of tunneling application GUIs, you can install putty client instead.

See also more detailed instructions here [1]

Installation of X server

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 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
  • echo $DISPLAY command should show a non-empty string (i.e. localhost:11.0)
  • Try running xeyes &

If you cannot run graphical applications

  • Most work in the course will be done on command line
  • You will however need a text-only editor:
    • Simple editor is nano (see keyboard shortcuts on the bottom of the screen)
    • More advanced are vim, emacs, ne (read tutorials before starting using them)

Copying files to/from the server

  • You can copy files using scp command on the command line
  • Alternatively use WinSCP program
