Reopening, because setting clientid in pxelinux.cfg/default is not an acceptable solution. The DHCP RFC states that the clientid should be unique on the local network, and not doing so causes serious problems with certain RFC-compliant dhcp servers.
The current udhcp package is ancient (>5 years old) and doesn't have the necessary "--clientid-none" switch . The udhcp codebase has been moved to busybox. That newer udhcpc does have the --clientid-none switch (line 165 in http://git.busybox.net/busybox/tree/networking/udhcp/dhcpc.c?h=1_16_stable&id=53283adb24765a7afb4d6298661c3c1a8d6f5601) So as soon as that new udhcp package lands in Ubuntu (https://bugs.launchpad.net/ubuntu/+source/udhcp/+bug/566845), we can drop --clientid completely and start using -C instead, which should be a proper solution to this bug report. ** Changed in: ltsp (Ubuntu) Status: Fix Released => Confirmed ** Changed in: ltsp (Ubuntu) Assignee: Alkis Georgopoulos (alkisg) => (unassigned) -- UDHCPC not fetching lease from Windows DHCP server https://bugs.launchpad.net/bugs/505916 You received this bug notification because you are a member of Edubuntu Bugsquad, which is subscribed to ltsp in ubuntu.
