[Bug 1088682] Re: dhclient does not register hostname to dynamic DNS (AD)

[Launchpad Bug Tracker]

This bug was fixed in the package isc-dhcp - 4.2.4-1ubuntu10.2

---------------
isc-dhcp (4.2.4-1ubuntu10.2) quantal-proposed; urgency=low

  * Fix isc-dhcp-server-ldap not actually containing ldap support.
    Thanks to Christian Hoffmann for tracking down the issue. (LP: #1071928)
  * Don't set fqdn.fqdn in dhclient.conf as that seems to confuse some DHCP
    servers. An alternative would have been to only set fqdn.fqdn and not
    host-name, but that appears to confuse another set of servers.
    For now go with just host-name which is the most common and if becomes a
    big problem for IPv6 (where fqdn.fqdn is apparently required), then we'll
    need to have a separate dhclient6.conf file and change all the calls to
    dhclient -6 to use that file instead. (LP: #1088682)
  * Include patch from RedHat/Fedora to deal with hardware/xen/virtio offload
    of UDP checksums. (LP: #930962)

Title:
  dhclient does not register hostname to dynamic DNS (AD)

  Fix Released
Status in “isc-dhcp” source package in Raring:
  Fix Released

Bug description:
  == Rationale ==
  Setting both fqdn.fqdn and host-name isn't quite supported. Various RFCs disagree on exactly what should be allowed and is further complicated by dhclient doing both dhcpv4 and dhcpv6.
  This change simply reverts to the pre-12.10 situation.

  == Test case ==
  1) Update to new isc-dhcp-client
  2) Get a new lease on a network using Windows DHCP server
  3) Confirm that DNS was updated.

  == Regression potential ==
  There may be a regression for people expecting fqdn.fqdn to be set on DHCPv6, this should affect a very small part of our users (if any) and our previous fqdn.fqdn value wasn't technically valid anyway (wasn't a fqdn).

  --- original bug report ---
  This is not working in quantal (4.2.4-1ubuntu10) and raring (4.2.4-3ubuntu1), but is working in precise (4.1.ESV-R4-0ubuntu5).

  A patch fixed an issue for bug 991360 where dhclient.conf was amended to include:
  send fqdn.fqdn = gethostname();

  This causes failures when the client tries to register was some DHCP servers (for example Windows AD DDNS servers).
  By commenting out this line and restarting the client, the client can then register with this type of DHCP server.

  However, this is needed to ensure dhcpv6 works.
