28-mar-2016: Welcome to our new server! Faster and less prone to crashing.

Welcome to the Slackware Documentation Project

Remote X: Windows to Linux

Plain Ol' Vanilla Remote X11

1) Install Xming and Xming-fonts

2) Add the Linux machine's DNS name(s) and/or IP address to the C:\Program Files\xming\X0.hosts file. File should look something like:

  Linux1.mydomain.com
  Linux1
  192.168.1.25

3) Start Xming

  • (NOT XLaunch)

4) Start the connection: Connect to the Linux machine via ssh/telnet/rlogin/whatever and run:

   DISPLAY=WINDOWS_IP:0;export DISPLAY;APPLICATION_YOU_WANT_TO_RUN
   EXAMPLE: DISPLAY=192.168.1.10:0;export DISPLAY;xterm

Minimize the telnet session, do not close it. If you close it, your X11 connection will close.


PROBLEMS

PROBLEM: “Xlib: connection to YOUR_IP refused by server”
FIX: Check the Xming log, it probably contains “Xming.exe: client 4 rejected from IP YOUR_IP”. If so,

  1. close Xming
  2. Make sure that the DNS names and/or IPs are in the C:\Program Files\xming\X0.hosts file
  3. restart Xming

FIX2: If problem is not fixed, restart Xming with the -ac option.

PROBLEM: Map starts but then I get a font error from OpenView.
FIX: Install the Xming-fonts onto your Windows box.

PROBLEM: When starting Xming, a Windows Security Alert pops up saying Windows Firewall has blocked this program.
FIX: Change Windows Firewall setting to allow Xming.
FIX2: Disable Windows Firewall by going to Services, setting Windows Firewall to MANUAL START and then stop the service.

PROBLEM: Cannot connect to Xming and I have checked all of the above.
FIX: When starting Xming as display 0, Windows Firewall does not complain. Check to see if Windows Firewall is blocking the connection.

Remote X11 Over SSH

1) Edit /etc/ssh/sshd_conf on the remote (Slackware) machine.

   CHANGE:
   #X11Forwarding no
   
   TO:
   X11Forwarding yes
   
   CHANGE:
   #X11UseLocalhost yes
   
   TO:
   X11UseLocalhost yes

2) Install Putty (if it's not already installed).

   www.chiark.greenend.org.uk/~sgtatham/putty/

3) Open putty and fill in the “Host Name” box.

4) Under Category > Connection > SSH > X11 check the “Enable X11 forwarding” box.

5) Click the “Open” button to start the connection.

6) Log into the remote machine as you would do in a normal SSH session.

7) Start the X application from the command line, a window should open on your local machine with the application.

(It's basically a regular SSH session with putty but with X11 forwarding enabled.)
