终于给我找到了一个好东西。看大家找不找到！？==========================TCPReflector A multithreaded java class that allows you to redirect all connections to a particular machine and port to another machine and port. To download the package: Click tcp.tar.gz to download as gzipped tar file Click tcp.zip to download as a zip file. If your unzip program cannot handle long filenames (many cannot) you may also want to download this one, it handles long filenames just fine. Click unzip.exe to download Once you have downloaded the package, to unpack it Unix: First run: gzip -d tcp.tar.gz Then run: tar xvf tcp.tar PC:Run: unzip tcp.zip Now you will have created a directory called TCPReflector. To run the program, change to that directory and run the following command: java TCPReflector -port 8888 -dest www.cnn.com:80Now put in the following URL into your favorite web browser http://localhost:8888/Viola, it takes you to cnn's homepage! Other potential uses for this program: To allow an applet to talk to a socket not located on the host from which it was served. You run the TCPReflector back on your server on a known port (which could be supplied to the applet via the PARAM tag) and set it up to connect the the host and port your applet needs to connect to. Then have your applet connect to the TCPReflector and it'll behave as if your applet has a direct connection to that host and port To "spy" on a particular network protocol in order to determine how it works. In the example using cnn's site above, if you add the additional switch "-echo" when you run the reflector you'll get to see the http protocol in action as your browser communicates with the web server * Modifications * 1999-12-07 by Carl Forde [email protected] * 1 - changed args -echo -quiet are default * 2 - added -noecho -verbose * 1999-10-14 by Carl Forde [email protected] * 1 - removed extraneous "\n" * 2 - default destination port is 80 * 3 - timestamp source/dest messages * 4 - changed names to client/server, server/client * 5 - added hex dump display Back to the java page ...
