ifdownThe ifup command makes network connections active, and the ifdown command brings them down. Why would you need to bring down your network connection? Most often, it's because you're trying to bring it up, and ifconfig reports that it's already up, but erroneously configured. So you first bring it down, and then bring it back up. # ifup eth0 ifup: interface eth0 already configured # ifdown eth0 # ifup eth0 Notice that ifdown, like ifup, is silent upon success. If you don't see anything after entering ifdown, the command was successful, and that network interface is no longer going to work. Note You can also use ifconfig eth0 down or iwconfig ath0 down to bring wired or wireless connections down. |
