.SH DESCRIPTION
|
|
|
|
This script expects a default single Ethernet interface setup, creates
|
|
a bridge named 'br0', and re-connects the Ethernet interface to this bridge.
|
|
|
|
The script bails out gracefully in case 'br0' already exists. In not, it
|
|
determines the name of the Ethernet interface, accepting both old 'eth*' and
|
|
new 'en*' naming, and verifies that it is a single Ethernet configuration.
|
|
Then it creates a bridge device named 'br0' and re-connects the physical
|
|
Ethernet interface to the bridge, preserving all IP addresses and routes.
|
|
|
|
This script is part of setting up tap devices with \fBip_create_tap\fR(1)
|
|
but can be used independently.
|
|
|
|
The script should be started as a normal user, but uses \fBsudo\fR(8) to
|
|
execute privileged commands, and might therefore ask for the user password.
