Hey guys I have a strange problem. There isn't an eth0 interface on my Linux embedded (ttylinux v7) client instead I have a dummy0 interface.With this interface I can't ping anything, and I think it does not work at all.If I run udhcpc to retrieve an IP during the boot process I can't get one (Sending discover.. No lease, failing). If I do the same after the login it works but the dummy0 continues there. That is strange because its a PXE boot so my dhcp server is running since the boot begins. I've already put the NOZEROCONF option on /etc/network.conf.
How to get rid of dummy interface?

The command ip link delete dummy0 is what you would use to delete it at the command line.  I have no idea why a dummy interface is getting created on your system though.
