  Description     : ifmetric is a Linux tool for setting the metrics of all IPv4 routes attached to a given network interface at once.


What is ifmetric for?

 I have a laptop with an onboard ethernet and a PCMCIA WLAN card. I
 never remove the latter. If both devices are connected to a network I
 want to priorize the copper over the wireless connection: it is faster
 and not subject to a restrictive firewall. Both network devices have
 default routes, it is left to chance which route is the first one
 created, thus the one used. ifmetric can be used to force the copper
 route to be selected: it manipulates the metric field of all routes
 connected to a certain interface, thus priorizing traffic over
 interfaces. It is compatible with DHCP clients as it modifies the
 routes a posteriori. A single line
 
up ifmetric $IFACE 1

 on the WLAN configuration stanza in /etc/network/interfaces
 priorizes all other interfaces.

 The routes are modified by using the NETLINK API of Linux >= 2.2,
 ifmetric is compatible with both iproute2 and traditional net-utils.

 Only a single binary, autoconf/automake is used, manpage included.
