How to make wicd set dhcp-based routing?

Question

I have a Beaglebone (Debian) with two network interfaces: eth0, usb0.

• usb0 is enabled by ifup from the system start (and used by udhcpd later)
• eth0 is started by wicd when users connects a cable

Here is routng table:

0.0.0.0         192.168.7.1     0.0.0.0         UG    0      0        0 usb0
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
192.168.7.0     0.0.0.0         255.255.255.252 U     0      0        0 usb0

The routing table does not work, eth0 should be routed via 192.168.0.1 gateway.

How could I make wicd

• get a gateway via dhcp,
• set up the gateway (and the route) for its interface.

I can do this in post-connection scripts or statically. I wonder if things can be done simpler via correct configuration of configs like wired-settings.conf?

Answer 1

If you cannot add something for a dynamic interface, you can remove the conflict from the static one. usb0 was statically defined in /etc/network/interfaces It is possible to delete a default gateway for usb0 via post-up, then you get the one from wicd correctly.

iface usb0 inet static
    address 192.168.7.2
    netmask 255.255.255.252
    gateway 192.168.7.1
    post-up route del default dev usb0
