让你的家庭也接入IPV6网络吧。

Posted by admin in ipv6

 

 

为什么我们中国的网络发展总是那么的滞后呢?

 

 

为什么我们国家的CNNIC总在叫着要加快IPV6的步伐! 可是却没有任何进展??

 

 

我们也不去报怨了。   现在让我们的家庭也接入IPV6吧。(不是指某一台机器哟)

 

 

要想让你的家庭也接入IPV6网络。肯定得有一段地址吧!    这个简单   申请吧! (是不是在想我去哪儿申请呢? )   

去国外申请。 为什么要去国外。  因为国外拥有大量的IPV6地址。人家的地址段可以约等于我们的地址位。

openvpn in Linux (FC5)

Posted by admin in 电脑网络, 资料

[root@localhost src]# gzip -dc openvpn-2.1.1-ipv6-0.4.10.patch.gz | patch –p1

 

ifconfig eth0 add 2005::4/64

route –A inet6 add default gw 2005::1

加入 /etc/rc.d/rc.local

 

cp /etc/sysconfig/network-script/ifcfg-eth0 /etc/sysconfig/network-script/ifcfg-eth0:1

Change device eth0 ==>eth0:1

 

 

OpenVPN 2.1.1 use bridge (TAP Driver)

dev tap0 (根据实际情况调整。)

 

Server-bridge 192.168.8.4 255.255.255.0  192.168.8.20 192.168.8.250

                   —————————————  ——————  ——————–

                                     |                               |                   |

                      服务端的IP地址和掩码        客户端分配的开始范围

 

如果启用了防火墙(Iptables)

iptables -A INPUT -i tap0 -j ACCEPT
iptables -A INPUT -i br0 -j ACCEPT
iptables -A FORWARD -i br0 -j ACCEPT

[root@localhost sample-scripts]# cat bridge-start

win7 会自动创建IPV6隧道?

Posted by admin in 电脑网络

    最近在配置OpenVPN服务器,准备拿来做为IPV6 用户远程接入。当我在本地计算机上测试网络联通性时,突然发现 我不会开任何的IPV6工具软件。也能PING通IPV6地址。

 

我计算机的系统是:

我的网络是:  内网环境 (IPV4地址为:192.168.77.*/24)   

 

    当时我正准备用PING测试一下服务器的IPV6地址能不能通,但是又忘了开启IPV6接入软件。  却惊奇的发现可以PING同服务器。
