Repeater Examples

  • Artikel

Let us suppose you have three computers, \\BOXA, \\BOXB, and \\BOXC, and you wish to use them as the server, the repeater, and the client, respectively.

You can start a debugging server on \\BOXA, using process 122 as the target, in the following manner:

E:\Debugging Tools for Windows> cdb -server tcp:port=1025,password=wrought -p 122

Then you can start a repeater on \\BOXB as follows:

C:\Misc> dbengprx -c tcp:server=BOXA,port=1025 -s npipe:pipe=MyPipe

Finally, start a debugging client on \\BOXC in the following manner:

G:\Debugging Tools> windbg -remote npipe:server=BOXB,pipe=MyPipe,password=wrought

Here is another example. Your symbols are at the remote location, 127.0.0.30. So you decide to use a process server on the computer where the target is, 127.0.0.10. You put a repeater at 127.0.0.20.

You also decide to use reverse connections. So you begin by starting the client on 127.0.0.30:

G:\Debugging Tools> windbg -premote tcp:clicon=127.0.0.20,port=1033 notepad.exe

Then start the repeater on 127.0.0.20:

C:\Misc> dbengprx -c tcp:clicon=127.0.0.10,port=1025 -s tcp:port=1033,clicon=127.0.0.10

And finally start the process server on 127.0.0.10:

E:\Debugging Tools for Windows> dbgsrv -t tcp:port=1025,clicon=127.0.0.20
