 ===== Starting a session =====

-A VNC session is started using the command **''vncserver''**. The first time you run this command, it will ask you for a password, as an additional security measure (this password can later be chnaged using the vncpasswd command, or by removing **''~/.vnc/passwd)''**
+A VNC session is started using the command **''vncserver -localhost''**. The first time you run this command, it will ask you for a password, as an additional security measure (this password can later be changed using the vncpasswd command, or by removing **''~/.vnc/passwd)''**
 Suppose your desktop is named **''eendracht.strw.leidenuniv.nl''** (so, replace this name with the name of your desktop wherever it is appropriate). The vncserver command will then print out a message like this:

 Remember the desktop name/number (e.g. eendracht:1), you will need it later to connect, since there can be more than one VNC session on the same computer.
+==== Security ====
+VNC will ask you to set a password. But for greater security, you may also want to restrict access to the running session, using the ''-localhost'' option on the ''vncserver'' command. With that option in place, only the local host can connect to the session (still requiring a password as well); for remote access to the session, you will have to connect through ssh, as explained below in the viewer-part of this page.
+Without ''-localhost'', machines on the same network as yours will be able to connect with just the plaintext password.
