Is it possible to use eth1 and usb0 at the same time?

Mate23 · 10-07-2007, 11:20 AM

Hi,

I've just finished setting up a basic debian disto on my handheld (loox720) and want to enhance this very basic distro by installing some useful packages. My problem is that the only way I can access my handheld is to do a 'ifconfig eth1 down' and ifconfig 'usb0 192.168.0.1 up'. Having deactivated eth1 i'm no longer connected to the internet but can on the other hand ssh to my device. Can someone help me?
Help appreciated

What do you mean by “the only way”? What happens if you don’t take down your first interface? What do the routing tables look like prior to and after bringing up your usb interface?

Hi,
Well,without bringing down eth1, i am unable to ping my device as it says 'Destination host unreachable'. If i do ifconfig usb0 192.168.0.2 i can ssh to my device (Notice: The SSH daemon on the device is automatically started). Changes is routing table after running ifconfig usb0 192.168.0.2:

Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 * 255.255.255.0 U 0 0 0 usb0

thanks for helping

So what does the routing table look like when you don’t bring down eth1 and bring up usb0?

Can you post the following three routing tables:

eth1 is up, usb0 is down (i.e., normal state).
eth1 is up, usb0 is up (the state where you get Destination host unreachable when trying to connect to something on the usb0 network)
eth1 is down, usb0 is up (where you can connect to your phone, but you have now lost internet access).

Also (this may be a silly question, but bear with me), you aren’t assigning the same address to both interfaces, are you?
