[HELP] Remote X applications

[brunok]

I'm excited about this distro! 

I am currently trying to use X applications remotely.
I have a CentOS server, with 2 network cards. A NAT network delivering DHCP and a TinyCore 8.2 image remastered via TFTP.
Working very well!


I need to run X applications with DISPLAY redirection to TinyCore client IP.


On the server I did:

export DISPLAY=10.1.1.10:0.0

Where 10.1.1.10 is my Tiny Client with Xvesa. Already modified .xsession file (removed no tcp listen option).

And I tried running rdesktop on the server, to open it in TinyCore, but get error "could not open display".


Any idea?

Rdesktop is an application to connect to windows terminal server sessions (the open source equivalent of mstsc.exe) and is not what you want. Running X applications remotely is different. There are different ways to do it, but for the kind of setup you are describing you probably want to use XDMCP. It is a little more automagic than the other ways. Otherwise it is a manual process that a person would probably only do on an as-needed basis.

Rdesktop is one example.

I've installed XMING in a Windows BOX and open FIREFOX in my Server CentOS.

Firefox GUI running in Windows BOX, but process, running in my CentOS.


Example:

CentOS: export DISPLAY=x.x.x.x:0.0
firefox &

Where x.x.x.x is Windows IP.


In my TinyCore client, value of $DISPLAY is :0.0

But get error in my CentOS. 

Error: cannot open display: x.x.x.x:0.0

You may need to play with access control too (-ac option to Xvesa), or maybe Xorg.

edit: Tested with two Qemu instances in a LAN. Removing "-nolisten tcp" and adding "-ac -tcp", X remoting worked. Naturally disabling access control with -ac is insecure, so please set up a firewall or other measures.

ITS AMAZING!!!

Updated my .xsession with -ac and -tcp flags.

Work like a charm!


THANKS!
