Suppose A and B know external IPs mutually. Can A and B talk directly? Is it easy to implement under Linux?
Any ideas are appreciated. |

发帖数: 434 | 2 怎么实现“A and B know external IPs mutually”？？？要安装啥软件、或申请啥服
务吗？
如果能实现这个，那我就可以在世界的任何地方，只要联上互联网，就可以看家里局域
网中linux os的set-top box上看家里的卫星电视了！！！

发帖数: 547 | 3 It's very simple. Let's say your computer B is behind the router.
1. set your router to expose your computer B
2. buy a domain name or go to step 4
3. If B is running on Linux, you can write some script to update the IP
address of the domain name;
4. If you don't want to pay the money, then let the script to report
the IP address by sending email to somewhere you like.

发帖数: 434 | 6 nice, but I still want to set up a home LAN(including router, satellite tv,
set-top box; or do I need to add a server?), and then I can do something on
it, ^^

发帖数: 434 | 7 Questions:
how to do #1?
for #2, yes, I bought a domain name.
for #3, yes, everything is running on Linux now; must B be a server? or just
a linux client, too? what script is it and where to put it on the B?
thanks again!!!

tv,

Why do you need a server? Just two yahoo or msn accounts are enough.
But this meant to be a joke.
You can consider something like slingshot that is meant for this purpose.

发帖数: 76 | 11 假设我们只能修改A和B，不能设置router，能够实现吗？
毕竟，设置router需要的知识不是每个人都有的。

发帖数: 434 | 13 oh, why we cannot config router? the router is at home, so we can access it
via ip in the home lan, right? there should be a management software in the
router already, right?
correct me if i'm wrong on this. thanks!

发帖数: 181 | 20 我以前成功的弄过,不知对你有否帮助
假设家里的router ip: homerouter
laptop ip: homelaptop
首先更新我的router(buffalo), 到http://www.polarcloud.com/tomato 下载相关的firmware
打开网页 http://192.168.1.1 (or some machine is 2.1, 0.1 )
username : admin
password: admin (若你第一次，多半是这个，你可以在里面改）
到port forwarding选项
让 homerouter:2000 port forward to homelaptop:22 (这步 最关键 ）
save and quit
现在空手到你的办公室，打开电脑
ssh -XY(graphic, optional) username@homerouter:2000 ( username is your
username on laptop )
输入密码
连上了
22=ssh scp rsync svn
这个对我有效，不知你 |
