New page

'''Virtual Network Computing''' or VNC allows a user to gain access to a computer through an established network. At [[Knox]], users can use the campus network to access their computers from any computer on campus using VNC software.

==Subnets==
''See main article at [[subnet]].''

Using VNC software on campus is slightly complicated because the school network is split into [[subnet|subnets]]. Student subnets are typically divided based on residence.

In order to access a computer that is on a different [[subnet]], you must first access a central computer called "[[Leibniz]]". This is a Linux machine that sits outside the [[subnet]] system.

[[Knox]] users can access this computer by using ssh and logging in with their Knox user names and passwords. Once in, the user may create a VNC server on their virtual machine which can be accessed by a VNC viewing client.

Once accessed by a VNC viewer client, the user may open another VNC viewer and gain access to the remote computer.

==Quick and easy guide==

===For Windows users===

===For Mac users===

====Download VNC software====
In order to access your computer from any other computer on campus, you will need a VNC server client. I would suggest [http://sourceforge.net/projects/osxvnc/ Vine Server] because it is free and easy to use. Once it is installed, run the application. It might be a good idea to put the application in your startup items list so that it is always running.

Note your IP address (example circled below). You may also enter a password if you wish to protect your computer. See Risks section below.

====Establish Leibniz server====
# Open Terminal (Applications/Utilities/Terminal.app).
# Type: ssh username@leibniz.lab.knet.edu and enter your e-mail password when prompted
# Type: vncserver
# Note the port number, which looks like :6. In the image below, my port number is :1

[[image:VNC_1.png]]

If VNC server (Vine Server) is running on your [[Mac]], then you are ready to access it from any computer on campus, including [[Windows]] machines.

==Accessing your computer==
# Once you have gone through the stages described above, your computer is ready to be accessed. The Windows machines in the computer labs have a program called Real VNC installed (Start-Programs-Real VNC). Run it.
# Type: username@leibniz:6 (the :6 is the port number you noted earlier.)
# Enter your password when prompted.
# You will now see your virtual desktop on [[Leibniz]].
# In the terminal, type: vncviewer
# Enter your IP address (which you noted earlier. Looks something like 10.3.2.4).
# If you are prompted for a password, enter the password you used for the VNC server client on your computer (REAL VNC for [[Windows]] or Vine Server for [[Mac]]).

And there you are.

==Risks==
By setting up a VNC client, you are allowing intimate access to your computer. You can set a level of protection for yourself by setting a password, but that password is all that is keeping someone on campus from being able to use your computer. So, consider yourself warned.
