[pkg-dhcp-devel] Bug#670865: isc-dhcp-client: dhclient does not send a hostname to DHCPv6 server by default

[Martin Jackson]

Package: isc-dhcp-client
Version: 4.2.2.dfsg.1-5
Severity: normal
Tags: patch ipv6

Dear Maintainer,

Stateful DHCPv6 requires a client to send the fqdn.fqdn option, not "host-name" as in DHCPv4.  I believe this issue can be patched trivially by adding the following line to dhclient.conf:

send fqdn.fqdn = gethostname();

This should not interfere with DHCPv4 hostname interaction and will enable 
clients to register with DHCPv6 stateful servers, such as ISC DHCPD 4.x.
