Using X from remote machine?

[Zmyrgel]

Okay,

I know that there's a way to use like KDE in my home machine from some other machine if they both are connected to each other. I've tried ssh connection but I don't know how I could use X. Could you give a quick tutorial? At least what thing to check.

Thank you.

You can use X applications from the remote system if you connect through ssh, use X11-forwarding or set the DISPLAY var to your local system, and start something like xterm.
If you wan't to use your complete KDE desktop you have to use something like VNC to get the screen from the remote system.

1. SERVER: edit the /etc/ssh/ssh_config file and set

Okay, the VNC seems to be the thing I'm seeking.

So it can be used so that I can basicly run KDE of my home machine and then connect to it on some remote Windows machine.

I'll see if I find info about the VNC.

If you want to control your complete desktop remotely, you might be interested in FreeNX, too. As opposed to X forwarding via ssh, NX compresses the X protocol considerably and is therefore well-suited for low-bandwidth connections like the internet.

There is a HOWTO right here: https://forums.gentoo.org/viewtopic-t-214455-highlight-freenx.html

I have never installed it myself, just saw several very impressive presentations. So sorry, if I can't be more helpful than that.

Oh, I forgot: FreeNX works seamlessly between Linux and Windows machines, in both directions.

using cygwin on windows or using a second virtiual terminal running X,
you can run your complete desktop environment remotely, wether it be kde, gnome, xfce, or any other:

in your current X session, start an xterm
in this xterm, run

[devsk]

How about XDMCP?

on remote machine:

1. emerge gdm
2. emerge kde
3. rc-update add xdm default
4. edit /etc/rc.conf to change DISPLAY MANAGER to gdm and XSESSION to kde-3.5 (e.g.)
5. edit /etc/X11/gdm/gdm.conf and enable XDMCP, and comment out 0=standard line if you don't want to start X on remote machine's video card.
6. /etc/init.d/xdm start

local machine:

run X with -query <ip of remote m/c>

X -query 192.168.0.10

replace with X with Xwin on windows from a cygwin shell.

Login normally as you do with local gdm.

This approach is slower than freenx or VNC on broadband but is minimal in setup and usage. Freenx is a PITA to setup and is very buggy.

BTW, the XDMCP works WAY better (faster and less cpu usage) than freenx and VNC on LAN. Both freenx and vnc are heavy on CPU.

GDM wants half of gnome emerged. Which I doubt anyone running another WM/DE wants.

standard xdm has XDMCP support as well, if you don't like the pretty gdm, and login is all you want.

also, you can change gdm above with kdm and adjust the corresponding setup file. hell, you can also replace it with CDE (remote solaris) and adjust the setup part. the point was about XDMCP, which works much faster and efficiently over LAN and decently over broadband compared to the proposed solutions.

[Pithlit]

Thought as much... I just wanted to point out gdm was unnecesary step. Glad we cleared that up.
