Bitvise X11 forwarding problem

You may have a problem trying to forward X11 from your Linux server through a terminal in Windows. I use Bitvise as the ssh client as it also provides the interface for sftp to download/upload the files. Not that using command line scp or sftp is not efficient, but in Windows you may have to install those tools separately.

Since I was trying to avoid installing Cygwin initially, Cygwin terminal wasn’t what I initially consider. Therefore, I went ahead and install Bitvise ssh client (instead of putty), which actually turns out to be quite good. The only problem (at least now) is when trying to forward GUI from the server with X11 forwarding, it failed miserably.

  • I’ve tried setting up bitvise in the X11 forward.
  • Installed X11-server from Cygwin (finally T_T).
  • But X11 forwarding still did not work. I got the error message below.

Failed to open channel for X11 forwarding from [::1]:47396 to Error connecting to X11 server: FlowSocketConnector: Failed to connect to target address. Windows error 10061: No connection could be made because the target machine actively refused it.

I kind of have an idea that this is something to do with Windows Firewall, which does not allow a specific port to listen to an incoming connection. But I haven’t quite figured out what to do. It is actually described on the bitvise page, but I guess I haven’t quite read the whole thing.

In short, after install cygwin X11 server, make sure to run the command below to fix the firewall permission. 

C:\cygwin64\bin\XWin -listen tcp -multiwindow
