Bug#634331: no longer works on a bridge interface

2011-07-18 Thread martin f krafft 
Package: dhcpcd5
Version: 5.2.12-1
Severity: normal

dhcpcd5 fails to obtain an address (it fails to put packets on the
wire) when the interface is a bridge. Manual configuration works, as
does IPv6 autoconf and isc-dhcp-client, so the problem seems to be
with dhcpcd.

Seems to work fine for me.

This is under ubuntu 10.04

How are you configuring the bridge interface and dhcpcd?
Does it work as the above?

Thanks
