Can't Start ISC DHCP IPv6 Server
- by MrDaniel
Trying to enable the ISC DHCP server for just IPv6 on Ubuntu 12.04 LTS.
I have downloaded and installed the DHCP server via the following command:
$ sudo apt-get install isc-dhcp-server
Then I have followed the instructions in the following resources, Ubuntu Wiki DHCPv6, SixXS - Configuring ISC DHCPv6 Server and Linux IPv6 HOWTO - Configuration of the ISC DHCP server for IPv6 .
So from review all those resources it seems like I need to:
set a static IPv6 address for the Interface I want to run the DHCPv6 server from that is part of the IPv6 network subnet outside the DHCP range.
Edit the /etc/dhcp/dhcpd6.conf file to configure the DHCPv6 range etc.
Create the /var/lib/dhcp/dhcpd6.leases
Manually start the DHCPv6 server.
Setting the Static IP for eth0
$ sudo ifconfig eth0 inet6 add 2001:db8:0:1::128/64
My dhcpd6.conf
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet6 2001:db8:0:1::/64
{
#Range for clients
range6 2001:db8:0:1::129 2001:db8:0:1::254;
}
Created the dhcpd6.leases file
As indicated in the dhcpd.leases man page.
$ touch /var/lib/dhcp/dhcpd6.leases #Tried with sudo as well
Manually starting the DHCPv6 server.
Attempted to start the server using the following command:
$ sudo dhcp -6 -f -cf /etc/dhcp/dhcpd6.conf eth0
The problem, the DHCP will not start, with an append error for the dhcpd6.leases file as indicated below when running the manual start command noted above.
Can't open /var/lib/dhcp/dhcpd6.leases for append.
Any ideas what I might be missing?
