...tches/broadcast_dhcp_send.patch found here: https://launchpad.net/ubuntu/+archive/primary/+files/klibc_2.0.4-8ubuntu1.debian.tar.xz It would be nice if it is correctly fixed upstream. as this bug affects lot of distros. Basically the function dhcp_send() at dhcp_proto.c mistakenly define bootp.yiaddr = dev->ip_addr; when in a client originated DHCP DHCPREQUEST(RFC2131 Page 36) it should be bootp.yiaddr = INADDR_ANY; // "0" and also it forgets to define the flags bootp.flags = htons(0x800); Best, Patrick Signed-off-by: Patrick Masotta <masottaus at yahoo.com> --- diff...

Hi all I'm trying to resolve a problem that's recently popped up by turning on auxillary VLANs for our Linux workstations. The problem shows as DHCP failling for anaconda (but always succeeds for PXE). I tried adding 'ipappend 1' to the pxelinux config files but had no joy. I'm thinking that if I write a COM32 module that adds "ip=1.2.3.4 gateway=1.2.3.1
