| + | If you want to force reset an interface completely, so that you can restart from scratch using the configuration in ''interfaces'', here's how: | ||
| + | |||
| + | First, remove the IP address from the interface: | ||
| + | |||
| + | <code> | ||
| + | ifconfig eth0 0 | ||
| + | </code> | ||
| + | |||
| + | Then, force the device to not be considered as up by ''ifup'', ''ifdown'' or ''ifquery'': | ||
| + | |||
| + | <code> | ||
| + | ifdown --force eth0 | ||
| + | </code> | ||
| + | |||
| + | Finally, bring it back online using ''interfaces'' config: | ||
| + | |||
| + | <code> | ||
| + | ifup eth0 | ||
| + | </code> | ||
