ubuntu下radvd,dhcpv6
上篇讲了ipV4 DHCP server.本篇继续讲述ipV6 server。环境如下
A: Ubuntu 14.04 + 有线网卡(eth0) + 无线网卡(wlan0)
B: Windows 7 + 有线网卡 + 无线网卡
A，B的无线网卡都连接到家庭无线路由器，网关为192.168.1.1，可以上互联网。A,B的有线网卡通过网线直连，A作为IPv6 server和网关，为B的有线网卡分配IPV6地址
3. vi /etc/radvd.conf (需新建该文件)，如下面几行
5. sudo /etc/init.d/radvd start
(如果在 radvd 运行状态下重启机器，radvd 会在开机后自动运行)
6. 在B上运行ipconfig
7.连通性测试
1.sudo apt-get install isc-dhcp-server
2.sudo vim /etc/network/interfaces
配置本机IPv6地址2001:db8:0:1::2
A:
1.sudo apt-get install wide-dhcpv6-server
2.sudo vim /etc/network/interfaces
添加IPv6地址2001:db8:1:2::120
3.sudo vim /etc/wide-dhcpv6/dhcp6s.conf
A: Ubuntu 14.04 + 有线网卡(eth0) + 无线网卡(wlan0)
B: Windows 7 + 有线网卡 + 无线网卡
A，B的无线网卡都连接到家庭无线路由器，网关为192.168.1.1，可以上互联网。A,B的有线网卡通过网线直连，A作为IPv6 server和网关，为B的有线网卡分配IPV6地址
一.A使用radvd(Router AdvertisementDaemon)为B分配ipv6地址
1.sudo vim /etc/network/interfaces
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.5.5.1 netmask 255.255.255.224 network 10.10.10.0 broadcast 10.5.5.31 #auto eth0 iface eth0 inet6 static address 2001:db8::1 netmask 642. sudo apt-get install radvd
3. vi /etc/radvd.conf (需新建该文件)，如下面几行
interface eth0 {
AdvSendAdvert on;
AdvManagedFlag off;
AdvOtherConfigFlag off;
prefix 2001:db8::/64{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
};
};
4. 在/etc/sysctl.conf 中打开 net.ipv6.conf.all.forwarding=1
5. sudo /etc/init.d/radvd start
(如果在 radvd 运行状态下重启机器，radvd 会在开机后自动运行)
6. 在B上运行ipconfig

7.连通性测试
A上：
ping6 -I eth0 2001:db8::2ca1:fa3d:7f0b:611b
PING 2001:db8::2ca1:fa3d:7f0b:611b(2001:db8::2ca1:fa3d:7f0b:611b) from 2001:db8::1 eth0: 56 data bytes 64 bytes from 2001:db8::2ca1:fa3d:7f0b:611b: icmp_seq=1 ttl=64 time=73.9 ms 64 bytes from 2001:db8::2ca1:fa3d:7f0b:611b: icmp_seq=2 ttl=64 time=0.398 ms

ping 2001:db8::1
C:\Windows\system32>ping 2001:db8::1 正在 Ping 2001:db8::1 具有 32 字节的数据: 来自 2001:db8::1 的回复: 时间=464ms 来自 2001:db8::1 的回复: 时间=62ms
二、使用isc-dhcp-server为B分配IPv6地址
A:1.sudo apt-get install isc-dhcp-server
2.sudo vim /etc/network/interfaces
配置本机IPv6地址2001:db8:0:1::2
3.sudo vim /etc/dhcp/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;
# Range for clients requesting a temporary address
range6 2001:db8:0:1::/64 temporary;
# 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
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.B上运行ipconfig
以太网适配器 本地连接: 连接特定的 DNS 后缀 . . . . . . . : domain.example IPv6 地址 . . . . . . . . . . . . : 2001:db8:0:1::254 本地链接 IPv6 地址. . . . . . . . : fe80::2ca1:fa3d:7f0b:611b%11 自动配置 IPv4 地址 . . . . . . . : 169.254.97.27 子网掩码 . . . . . . . . . . . . : 255.255.0.0 默认网关. . . . . . . . . . . . . : ::此时ping 2001:db8:0:1::2 不通
netsh interface ipv6 add route ::/0 "本地连接" 2001:db8:0:1::254 publish=yes
C:\Windows\system32>ping 2001:db8:0:1::2 正在 Ping 2001:db8:0:1::2 具有 32 字节的数据: 来自 2001:db8:0:1::2 的回复: 时间<1ms 来自 2001:db8:0:1::2 的回复: 时间<1ms 来自 2001:db8:0:1::2 的回复: 时间<1msA上ping 2001:db8:0:1::254 连通 三、使用wide-dhcpv6-server给B分配IPv6地址
A:
1.sudo apt-get install wide-dhcpv6-server
2.sudo vim /etc/network/interfaces
添加IPv6地址2001:db8:1:2::120
3.sudo vim /etc/wide-dhcpv6/dhcp6s.conf
# The followings are a sample configuration to provide a DNS server address
# for every client as well as to delegate a permanent IPv6 prefix
# 2001:db8:1111::/48 to a client whose DUID is 00:01:00:01:aa:bb.
option domain-name-servers 2001:db8::35;
host kame {
duid 00:01:00:01:aa:bb;
prefix 2001:db8:1111::/48 infinity;
};
# The followings are a sample configuration to provide an IPv6 address
# from an address pool 2001:db8:1:2::1000-2000 for 3600[s].
# Note. You have to send an RA to fxp0; otherwise a client cannot be sure
# about the prefix-length and the default router. If you want to prevent
# stateless address configuration via RA, please set the autonomous-flag to
# OFF in your RA configuration.
interface eth0 {
address-pool pool1 3600;
};
pool pool1 {
range 2001:db8:1:2::1000 to 2001:db8:1:2::2000 ;
};
