Binary package hint: isc-dhcp-server
(isc-dhcp-server 4.1.1-P1-15ubuntu9 on Ubuntu server 11.04)
It's impossible to run dhcpd with the -6 flag with the current apparmor config in the isc-dhcp-server package. I added a patch that fixes this problem, apply with "cd / ; patch -p1 < dhcpv6support.patch".
TEST CASE:
1) Copy /etc/init.d/isc-dhcp-server to /etc/init.d/isc-dhcp-server6
2) Copy /etc/dhcp/dhcpd.conf to /etc/dhcp/dhcpd6.conf
3) Apply the patch from http://paste.ubuntu.com/706208/ to isc-dhcp-server6
4) Run: update-rc.d isc-dhcp-server6 defaults
5) Edit /etc/dhcp/dhcpd6.conf to look like:
---
authoritative;
option dhcp6.name-servers 2001:470:20::2;
option dhcp6.domain-search "ubuntu.com", "stgraber.net";
# testv6-dhcpv6
subnet6 2001:470:8cc0:9002::/64 {
range6 2001:470:8cc0:9002::128 2001:470:8cc0:9002::254;
}
---
6) create an ipv6 address on the same network 'ip -6 addr add 2001:470:8cc0:9002:127/64 dev eth0'
7) /etc/init.d/isc-dhcp-server6 start
This will fail with isc-dhcp-server version 4.1.1-P1-15ubuntu9.1 installed and apparmor.
You will see something like the following in syslog - apparmor="DENIED" .. profile="/usr/sbin/dhcpd"
With the -proposed version isc-dhcp-server and isc-dhcp-common step 6 will start okay.
I also added a second file that can be placed in /etc/init.d/ as 2nd init script to launch the server in v6 mode (if you run "diff /etc/init.
This init-file is only optional, it is not needed to fix the bug. (but it would be nice to include it even if you don't place it in any runlevels)
A default /etc/dhcp/
