Remote control your Linux box (VNC ~= Remote Desktop on Windows)

For those who visit or live in the Windows world the built in Remote Desktop client and server capabilities are quite handy for administrative tasks.  It allows you to log onto one Windows computer via another.

Windows on the server side (the one you want to control, not necessarily a server)
  • right click on My Computer > Properties > Remote tab
  • ensure that remote Desktop "Allow Connections" is selected

Windows on the client side
  • (Win 7 / Vista) All Programs > Accessories > Remote Desktop
  • (Win XP) All Programs > Accessories > Communications > Remote Desktop  
pop in the host name & click on connect.


While administrators of Linux boxes generally will connect using ssh, to use a command line interface, the demand for GUI based remote control has increased.  So here are some instructions for configuring VNC on Linux if ssh & cli are not enough for you (note the instructions do not include ssh tunneling of VNC,  see future posts for tunneling):


Linux server & client instructions Configure Fedora 12 - 13 VNC remote access 

For a windows client download and install VNC Viewer it is a stand alone application.

Have fun with your neighbours!

So somebody is piggy backing on your wireless network?


I am of the mind that it's no harm no foul if someone occasionally uses my wireless.  I also support the ideas and use of http://www.ilesansfil.org/  but where I live it hasn't been adopted much, I think it has to do with population density 'burbs vs urbs?? 


However if someone is slowing your network or using it for nefarious purposes you may want to lock them out or mess with their heads:

The essential idea is that you split your network into trusted and unknown using DHCP.  Then you have some fun with the unknowns: the two suggestions are
  1. send all traffic to kittenwar.com 
  2. reverse all of the images  using a simple perl script &  the mogrify binary from ImageMagik
I'm sure you could come up with something else !!
