Date: 2012may1 OS: Linux Distro: RedHat/Fedora/CentOS Q. How do I start/stop my ethernet/internet connection? A. Assuming everything is installed and working, these are the commands:

ifup eth0 # Bring ethernet zero up (start) ifdown eth0 # Bring ethernet zero down (stop) ifconfig eth0 # See the status of ethernet zero ifconfig # See the status of all network interfaces

If you prefer a text GUI:

system-config-network-tui
