By default on many installs [X] disables remote connections with a nolisten parameter to it. |
| |
|

|

So try and find this by something like <tt>sudo grep -n -r nolisten /etc</tt> and then comment this out from the appropriate file. Restart [X]. |

Then on a shell on the local machine type <tt>xhost +</tt> (or alternatively a host name instead of +). Then on the shell on the remote machine type <tt>DISPLAY = host:0.0 ; export DISPLAY</tt> where host is the hostname of the local machine. Now start your program in the remote shell by typing the commandline startup e.g. <tt>openoffice</tt> and it will appear on your local desktop. |

A better way of doing this; use "ssh -X" when you connect to the remote host. This will set up an encrypted tunnel for programs on the remote system to communicate with the X server, and set up the DISPLAY variable to use it. |

!!What do these X display names mean? eg : 192.168.1.4:0.0 |
| |
|

|
| |
|

An X display name is in the form: hostname:displaynumber:screennumber |
| |
|
15 |
|
| |
|
16 |
hostname |
| |
|
17 |
The hostname specifies the name of the machine to which the display is physically connected. If the hostname is not given, the most efficient way of communicating to a server on the same machine will be used. |

displaynumber |
| |
|
19 |
The phrase "display" is usually used to refer to collection of monitors that share a common keyboard and pointer (mouse, tablet, etc.). Most workstations tend to only have one keyboard, and therefore, only one display. Larger, multi-user systems, however, frequently have several displays so that more than one person can be doing graphics work at once. To avoid confusion, each display on a machine is assigned a display number (beginning at 0) when the X server for that display is started. The display number must always be given in a display name. |

screennumber |
| |
|
21 |
Some displays share a single keyboard and pointer among two or more monitors. Since each monitor has its own set of windows, each screen is assigned a screen number (beginning at 0) when the X server for that display is started. If the screen number is not given, screen 0 will be used |
