How to turn your box into a Xvnc Terminal Server

[Ssl]

Hi,

Really nice topic - thanks everyone, especially author (lines)

Few questions:

7) Specify who can have access to
edit /etc/X11/xdm/Xaccess and uncomment the line " '* #any host can get a login window" by removing the single quote
You could also change it to 192.168.0.* for some security


I have similar line but not the same. My line is:

[Ssl]

Ok, unmerged vnc and installed tightvnc and now I have this:

slobo@localhost slobo $ vncviewer localhost:71
vncviewer: VNC server closed connection

nothing more. Log in /home/slobo/.vnc/localhost:1.log

[Raybdbomb]

i followed the guide exactly, to the T

i tried xdm and gdm, and both give the error message when trying to run vncviewer:71

[Raybdbomb]

ok it works if i manually start the Xvnc server... but it doesn't load up a login, it just has the grey screen with cursor

i'll look through these other replies

Oooooh This is sooo kewl man! I love it! Now we all have Xwindows and KDE running remotely.

But you forgot to mention the following:

Ist ja ganz nett dein Script, aber wie bekomme ich es hin das er die Sitzung beim schleißen des Client-Fensters aufrechterhält, ist nämlich nervig das Fenster bei allen Operationen geöffnet zu lassen.

Aber ansonsten hat es mich schwer beeindruckt.

Sorry, i have written at the same time in an German Forum and haven't thought about it.
I find your script very useful, but when i log off the current display won't stay open it will close and you must login every time when you close the Remote Window and reopen it. I need that the session stays open because of some Compilation an the other PC so it is not very useful for me, but i have got found out how i can do that what i want on another way.
But when it give a possibility to force the session to stay open, please tell me, because i haven't found out how.

Hi,

I just came across something in which you guys might be interested... and maybe someone could even offer a solution...
I just spent a good 4 hours to figure out why I only get grey screens when trying to vnc into my notebook... it works like a charm the other way around (NB to Desktop) and the configuration files are identical...

I have been running a Cisco wireless card on eth1/wifi0 and that was the only ethernet interface at the time. I then finally thought about using the build-in wired port and it worked, I was blown away...
And what was really strange was that it didn't even work locally on the notebook... a vncviewer localhost:72 always gave me a grey screen...

So, maybe that will solve some grey screen problems... but does anyone know how to fix this? I am not too got with X networking and all, but there must be some kind of solution so I can use both devices.

Thanks,

Treo

Worked exactly as described, (xdm + fluxbox). Just set your new services (there is no need to include all the services, just the ones you really need), set up the entries for the xinetd deamon, allow any client to get access to the login screen (comment out that line on the Xaccess file), restart gdm and xinetd, and open corresponding ports on the firewall. If you only use one resolution, just open one port. Works flawlessly over the internet at 1024x768x16 with a cable connection.

Thanks again.

NOTE: anybody know about any security risk when running this kind of setup. I am going to configure some servers like this for remote administration. Is there any problems?

Old thread, sorry all . Lechuga do you have a link or a guide or something on how to set that up?

[Lechuga]

I don't have anything ready made, but I'll try to make something up.

Ok. If you're using Windows client and a VNC viewer (say UltraVNC, why not?) then you only need PuTTY to setup an SSH connection from Windows and then tunnel your VNC connection through it, making it safe from prying eyes. This is how:

1. Start up "putty"
2. Enter your hostserver in the "hostname" field (duh!)
3. Follow the option tree on the left to the bottom to "Tunnels"
4. Add new forwarded port as follows:
a. Source port: 5961 (for example, this gives you 800x600x16)
b. Destination: yourhost:5961
5. Click on open. You should now be able to login to your host with your username and password (still text mode).
6. Now start your VNC viewer and point it to locahost:5961

Isn't it great when things are this simple?

That's it! Good luck.

I changed /etc/X11/xdm/Xaccess to only allow connections from my network (192.168.110.*), but it still allows connections from any IP address. Has anyone else checked this?

Is anyone else having trouble getting this to work with xorg? I tried tracing the problem and the most I could get it to do was give me the black & white screen and X mouse cursor by specifying font paths manually in the xinetd services file. I was thinking the problem was the font paths because xorg moved them to /usr/share/fonts. Anyways without specifying the font paths manually, I only get a response on the console "VNC connection closed by server" or something to that effect.

Thanks for the great tutorial, been wanting to do this for a while.

[Roderik]

YES! it finally worked for me

i only have one very annoying problem left, as you can see below, it doesn't show icons etc. I mean to use it in my LAN to the gentoo server without a screen over a 100mbit, largely unused network, so all the effects could transmit without a loss of speed...

[EDIT] ok, got it, don't open a 32bit vnc on a 24bit TFT screen

Is there a way of getting this methodology working with the java http client?
