ipv6 dhcp server－阿藏哥的部落格~不應該阿

小編因為工作需要所以用Ubuntu 14.04 架ipv6,由eth1來發ipv6

1. sudo apt-get install isc-dhcp-server 先安裝套件

2. 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.

sudo ifconfig eth0 inet6 add 2001:db8:0:1::128/64 (或直接去設定固定ipv6,請參考這篇:http://pk5566.blogspot.tw/2011/01/ubuntuipv6.html)

3. Edit the /etc/dhcp/dhcpd6.conf file to configure the DHCPv6 range etc.

但設定檔只有#/etc/dhcp/dhcpd.conf所以來建一個設定檔給ipv6用.指令如下

#cd /etc/dhcp/

# cp dhcpd.conf dhcpd6.con

#nano dhcpd6.con

內容如下

[ configure 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;

# Additional options

option dhcp6.name-servers fec0:0:0:1::1;

option dhcp6.domain-search "domain.example";

# Prefix range for delegation to sub-routers

prefix6 2001:db8:0:100:: 2001:db8:0:f00:: /56;

# Example for a fixed host address (可加,可不加)

#host specialclient {

#host-identifier option dhcp6.client-id 00:01:00:01:4a:1f:ba:e3:60:b9:1f:01:23:45;

#fixed-address6 2001:db8:0:1::127;

}

4. Create the /var/lib/dhcp/dhcpd6.leases

是沒這檔案,需要自己建立,指令如下

#cd /var/lib/dhcp

# cp dhcpd.leases dhcpd6.leases

#nano dhcpd6.leases

把你裡面容全部砍光光就可以了....YA,並存擋

5. Manually start the DHCPv6 server. 指令如下

#touch /var/lib/dhcp/dhcpd6.leases

#sudo chmod 666 /var/lib/dhcp/dhcpd6.leases

#chown dhcpd:dhcpd /var/lib/dhcp/dhcpd6.leases

#sudo dhcpd -6 -f -cf /etc/dhcp/dhcpd6.conf eth1

就可以成功啟動ipv6

正確啟動會秀出
