The scripts 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. Than 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 normal user, but uses \fBsudo\fR(8) to execute priviledged commands and might therefore ask for the user password. . .\" ------------------------------------------------------------------ .SH "SEE ALSO" .BR ip_create_tap (1) .\" ------------------------------------------------------------------ .SH AUTHOR Walter F.J.
