TCP通过UDP？ [英] TCP thru UDP?

问题描述

我从一个办公室到另一个办公室有一个持续的UDP连接。我使用

它用于内部应用程序，它工作正常。


但是，我想将文件传输添加到我的小应用程序而不需要另一个

端口在防火墙上打开，我不想重新发明TCP轮。


有没有办法通过我现有的UDP隧道TCP连接并采取TCP提供的用于传输文件的数据包检查的优势？

I have a constant UDP connection from one office to another office. I use
it for an in-house application and it works just fine.

But, I want to add file transfer to my little app without requiring another
port be opened on the firewall and I don''t want to reinvent the TCP wheel.

Is there a way to tunnel TCP through my existing UDP connection and take
advantage of the packet checks that TCP offers for transfering files?

推荐答案

通常在局域网没问题，TFTP（UDP base）对局域网来说非常好用，但是如果你重新发明TCP轮子，你需要使用TCP，否则你需要使用TCP可以使用第3方s / w这样做:)

Usually within LAN that be OK, TFTP ( UDP base ) work pretty nice for LANs,
but if you "reinvent the TCP wheel"
you need to use TCP, otherwise you can use 3-th party s/w which did that :)

查看 http://gray-world.net/pr_cctt.shtml


他们说它可以在UDP内部隧道TCP。我没有测试过。

应该有其他工具可以做。


干杯，

Have a look at http://gray-world.net/pr_cctt.shtml

They say it can tunnel TCP inside UDP. I''ve not tested that.
There should be other tools that can do.

Cheers,
Armin

如何避免在防火墙上打开另一个端口？您将需要

来打开用于TCP-over-UDP协议的端口，因为它将与您所用的任何端口不同
重新使用常量UDP

连接 （我不知道你的意思，BTW）。

How does this avoid opening another port on the firewall? You''ll need
to open the port that''s used for the TCP-over-UDP protocol, since it
will be different from whatever port you''re using for your "constant UDP
connection" (I have no idea what you mean by that, BTW).
