Fwd: how to - XDMCP/LightDM - remote only
There were 4 questions and environment descriiption in the mail i sent yesterday, but robot ate them and moderators can not help recovering them Hope they still would help later, but they did not yet. Okay, main question was, how can i setup the box so that LightDM/XDMCP was available on TCP but was not run locally ? I do not want local X server run on the remote headless box, and i want be able to log into the box from remote Windows client. ssh x forwarding is practically unusable with Mate and other DEs -- Forwarded message - От: Arioch The Date: пн, 5 апр. 2021 г. в 14:09 Subject: Fwd: how to - XDMCP/LightDM - remote only To: Hello guys.

gmd3 fails to open X sessions on the console and on X servers using xdmcp (stretch 9.1)
Hello,
A few months ago I met no difficulties to configure our debian Wheezy
server to manage X sessions with gdm3, on the console and on a set of X
servers (Windows PC with Cygwin/X) using xdmcp.
I was unable to retrieve this functionality after a dist-upgrade to
Jessie (cf. https://lists.debian.org/debian-user/2016/10/msg00437.html),
and astonished by the lack of advices from this forum and other
channels. I hoped that Stretch could permit me to retrieve it. The
dist-upgrade from Jessie to Stretch was perfect but let unsolved our
problems with gdm3.
May be does it work on a fresh install ? On my upgraded server it
doesn't and I fail to progress. I don't know whether the problems are
due to wrong file permissions somewhere, wrong values for some
parameters, or to problems on which I can't get a grip on, or even to
the gdm3 package. They probably are not the same for the console and the
xdmcp requests.
Sorry for this long email. You may find more details on
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=873199.
Any advices and ideas are welcome!
1. For the console
The server reboots without any error and finishes with a last message
telling that GNOME Display Manager has started but nothing else is
displayed (no greeter, no prompt). I have to type Alt-Ctrl-F3 (or F4,
F5, F6) to get a login prompt on tty3 and open a terminal on the
console. I can also connect with ssh -X from other Linux workstations.
In /var/log/messages the first errors during the reboot could let think
to problems between gdm and cgmanager:

Then a loop with the same sequence of errors until the final relief
('too many opened files'):

Aug 22 18:40:58 my_stretch_server udev-acl.ck[22141]:
g_slice_set_config: assertion 'sys_page_size == 0' failed
which seems the last message about the problem.
Just after this reboot, gdm3 service seems happy:
systemctl -l status gdm3

Curiously it seems that there has been no attempt to launch X on the
server (Xorg.0.log not modified during the reboot), despite a loop to
try to create and display the gdm greeter on the console (from
/var/log/debug).
2. For xdmcp requests from other X servers
On the workstation (Windows 7), a few seconds after having launched
Cygwin/X with 'XWin:0 -query my_stretch_server ...', I get a window with
the following message:
A fatal error has occured and Cygwin/X will now exit.

Do not work XDMCP GDM3
Dear Maintainer,
I'm setting up a server for multi-user use.
For this I use XDMCP, GDM3, xinetd, TightVNC
I changed the settings of /etc/gdm3/daemon.conf to:
[daemon]
[security]
DisallowTCP=false
[xdmcp]
Enable=true
MaxPending=4
MaxSessions=16
MaxWait=30
MaxWaitIndirect=30
PingIntervalSeconds=60
MaxPendingIndirect=4
DisplaysPerHost=2
HonorIndirect=true
Port=177
[greeter]
[debug]
Enable = true
Settings for /etc/xinetd.d/vnc:
service vnc
{
disable = no
socket_type = stream
protocol= tcp
wait= no
user= root
server = /usr/bin/Xvnc
server_args = -inetd -once -query localhost -geometry 1024x768 -depth
16
type= UNLISTED
port
}
Settings for /etc/xinetd.conf:
defaults
{
log_type = SYSLOG daemon info
log_on_success = HOST PID USERID
log_on_failure = HOST USERID
cps = 200 5
}
Added to / etc / services:
vnc 5900/tcp#vncserver
But after all the changes, when connected through the client, only the
gray screen appears.
Made the configuration for a specific user .vnc / xstartup:
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP
Desktop" &
#x-window-manager &
# Fix to make GNOME work
export XKL_XMODMAP_DISABLE=1
gnome-terminal &
mutter
/etc/X11/Xsession
When connected to an active user, everything works fine.
I need to, when connecting to a remote session, a window manager is
loaded where it is possible to select a user. When using Ligthdm this
happens, but I would like to use GDM3.

With Jessie 8.6, gdm3 and XDMCP, the GDM face browser is built but not displayed (without the attached file)
Hello,
I have sent yesterday the following message (slightly modified this
morning) but committed the mistake to attach a too big file (I thought
that a file of 27700 bytes was not too large - Sorry...). Maybe some of
you have already received it, but I think that it is not the case for
most of you. So I send it again, without the attached file that can be
found at:
https://lists.debian.org/debian-user/2016/10/msg00417.html
This attached file contains lines extracted from /var/log/system and
/var/log/debug (uncompress it with bunzip2 after having renamed it in
something.bz2)
We used during 2 years Gnome and gdm3 on a server with Debian Wheezy to
let users open sessions from their Windows PC via Cygwin and xlaunch
(xdmcp). It worked well till the upgrade to Jessie 8.5, for these
Windows PC, as for the system console. The upgrade to Jessie 8.6 didn't
solve the problem. I have already tried to describe these problems the
09th of september ("gdm3 doesn't work any more after the upgrade from
Wheezy to Jessie 8.5") :
https://lists.debian.org/debian-user/2016/09/msg00301.html
As users were satisfied by the environment provided with gnome, when the
server ran on Wheezy, I am still trying to launch gdm3.
The story is the same for the console (when the system restarts) and for
the Windows PC (at each launching of xlaunch): I get during a split
second a gray background screen, probably corresponding to the GDM face
browser, followed during a new split second by a nice blue screen
(debian 8 on the bottom-left corner, date and time on the middle, and a
few icons on the upper left which are able to display information about
the connection to the network), followed by a dark screen, till the
first mouse or keyboard event, that activates definitely the blue
screen. For the console the dark screen is very ephemeral and has
appeared only once, before the blue screen is displayed. I have tried to
understand what happens really and read carefully the /var/log files. It
is clear that the GDM face browser with the list of all users is being
built, but I have not yet understood why it is not displayed : warning
and errors traced in these files should be more understandable for a
person more expert than me in Gnome and gdm3. I have prepared a file
with extracts from /var/log/system and /var/log/debug, compressed with
bzip2 ...
I have read the warning about the upgrading from wheezie to jessie:
5.10. The GNOME desktop requires basic 3D graphics
The GNOME 3.14 desktop in Jessie no longer has fallback support for
machines without basic 3D graphics. To run properly, it needs either a
recent enough PC (any PC built in the last 10 years should have the
required SSE2 support) or, for architectures other than i386 and amd64,
a 3D-accelerated graphics adapter with EGL drivers.
It could mean that was I am trying to do is no more possible. But during
the 3 first days just after the upgrading to Jessie 8.5 I had a degraded
but nearly working situation with Windows PC: a few minutes to get the
GDM face bowser, again a few minutes to get the session, which was then
normal but impossible to close, and sometimes nothing. My attempts to
improve the situation lead to a much clearer one: what I get now is
always this nice blue screen, maybe built by gnome-screensaver (I am not
sure at all). That was not exactly my aim... But it lets me think or
hope that I am not in the case reported in the warning 5.10.
Today I don't ever know whether the problem I try to solve may be solved
or not, and if it is due to an error of installation (lacking packages
to install or packages to uninstall), or an error of configuration
(despite my attempts to compare the new and the previous ones for gdm,
pam, ...), an error in Cygwin installation (lacking packages) or,
possibly, a bug of Jessie.
It would be nice if someone could answer that it works on his system :
Jessie, gdm3 with xdmcp enabled and Windows PC emulating a X11 server
with xlaunch (through Cygwin or another free software) to open sessions.
The problem is not important for the console, as I can leave the blue
screen with Ctrl-Alt-F1 and open a non-graphical session on tty1, which
is enough for my needs. It is more annoying for the Windows PC.
Many thanks in advance ! Best regards,
Jean-Paul

It's worth noting that xrdp uses VNC behind the scenes, which isn't the most CPU-efficient. XDMCP may perform better, so both are worth looking into, particularly if xrdp is performing poorly. The places where I've been using xrdp have been in situations where we've had no more than about 3 users simultaneously, and xrdp was chosen because it makes life easier for the Windows users to access a box. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.

I realise you're looking for XDMCP as the solution, but just pointing out the other is an option. So, for XDMCP, you need a display manager running on the server that supports it. gdm2 , lightdm, kdm and xdm all do. gdm3 might too, I haven't tried. For 'lightdm', if you edit or create /etc/lightdm/lightdm.conf and add: [XDMCPServer] enabled=true then restart it, you should find the server listening on port 177/udp. For 'kdm', look for /usr/share/config/kdm/kdmrc and in there, you should see a section called 'Xdmcp'. 'gdm2' had a similar procedure. The thing to look for after re-starting the display manager is that something is listening on port 177/udp. Then you should be able to get your X terminal to query it and things should JustWork. A useful way to test is on another box with X: X -query yourserver :1 You should see X start up and log in to your designated server. At worst you might need -from your-ip for that to work.

how to get gdm3 greeter to display menu of hosts for remote login via xdmcp
How do I get the gnome3 greeter to give me a menu of hosts on the local network who are willing to accept an xdmcp login? On my "squeeze" machines running gdm, at the login screen there is a drop-down called "Actions" that has one option called "Remote login via xdmcp". When I choose that option, I get a list of hosts on the local network who are willing to accept logins via xdmcp. But on my "wheeze" machine, first of all there's no "Actions" drop down at all, and I can't find any other way to get the list of xdmcp accepting hosts. Does anyone know what magic I'm missing? Is there something I can put into one of the files in /etc/gdm3/ that will enable the remote host chooser? Thanks in advance!

Then it seems that GDM3 allows every host to access directly and indirectly. Several configuration examples that cover all of xdm, gdm and kdm seem to suggest this. They explicitly mention mention Xaccess for both xdm and kdm but leave it out for gdm. If GDM3 still behaves like the older GDM I guess http://library.gnome.org/admin/gdm/stable/configuration.html.en has the answer: HonorIndirect=true Enables remote execution of the chooser, 'true' seems to be default. Regarding access control the document says: "If GDM is compiled to support it, access from remote displays can be controlled using the TCP Wrappers library. The service name is gdm You should add gdm:.my.domain to your /hosts.allow, depending on your TCP Wrappers configuration."

XDMCP and GDM3
Hi list, a while ago we played a bit with XDMCP at the local LUG gathering here in Frankfurt, Germany. One machine was running KDE 4.6.5 (sid) and the other Gnome 3 (squeeze). We managed to get a Chooser on each machine from the respective other machine by issuing X :1 -broadcast -indirect Each time the Chooser offered both machines. Now to my question. I know which files control the KDM behavior in regard to XDMCP (kdmrc and Xaccess, both in /etc/kde4/kdm/). But for GDM3 I have no idea where this is done. It just worked. Xaccess at /etc/X11/xdm/ had no influence so it must be somewhere else. But where? Any clues?

There's also chooser, but the laptop's gdm doesn't find anything on the LAN. I don't need two xservers on the desktop, but it should allow local and remote inbound connections.

Yeah, I read the idea about module aliases as well, but it seems pointless since IPv6 isn't a module on my system (using the 2.6.32-3-amd64 kernel from squeeze). It's interesting however that you say that you expect it to work with IPv4 even though it has only bound the ipv6 socket. I guess you could be right (depending on how the actual ipv4-to-ipv6 stuff works...). In my case however, I can't get a working XMDCP login screen so I'm suspecting this is the problem.

It can't be binding to an interface that doesn't exist, so it sounds as though you haven't disabled it properly. You can type '/sbin/ifconfig' and look for inet6 entries. You shouldn't have any if IPv6 is disabled. You can check for anything listening on IPv6 with 'netstat -l6'. Have you looked at the Debian wiki page at 'http://wiki.debian.org/DebianIPv6'?

IPv4-capable XDMCP server in Debian squeeze?
Hi there! Isn't there any XDMCP-capable server available in squeeze that can speak ipv4 any more? I read about the "net.ipv6.bindv6only" issue (in a bug report). However, that setting is most assuredly set to 0 when I check with sysctl -a. I also forcibly disabled IPv6 support altogether (since I don't need it), also by using a sysctl interface, but it still doesn't help me. Both when trying with xdm and gdm, they *only* bind to the udp6 socket. Quite broken if you ask me, _especially when ipv6 support is disabled in the kernel_! I haven't tried with KDM so far (and I'd rather not, since I have no interest in running KDE). Any hints? The reason I want IPv4 XDMCP is that I will connect to the server from a Windows XP machine, using Xming. I wasn't aware that this has suddenly become an awful lot of work, since the introduction of the wonderful new toy called IPv6... :-) (Please, Cc any replies to my email address since I don't subscribe to the mailing list.

XDMCP session, lenny client: pictures are displayed as black area
Hi, A lenny client makes XDMCP, server is a suse 9.2 machine. Images (simple black-white-scans 100kB) are displayed with "kuickshow" application as area completely in black . Why? Using gwenview instead of kuickshow all pictures are displayed korrectly - but gwenview 1.1 in not usable, too many bugs. And no update of gwenview possible ... Using suse 10.1 als client installation that makes XDMCP and all works: kuickshow displays the pic's korrectly. I know that because the client before has had Suse 10.1. But its quite an effort to change the installation, so: any ideas why lenny client prevents the kuickshow viewer to show pictures correctly?

XDMCP in GDM Not Working
I have GDM XDMCP enabled. However, when I select on the GDM screen to login to a remote system via XDMCP, the system scans the netowrk and then returns a claim of No Serving Hosts Were Found. I know this is wrong, because another box on my network is also XDMCP enabled, and its GDM chooser is only showing itself as an available host. Both systems are running Debian Unstable. The one that can at least see itself is running an older version of GDM (I have no idea what version). The other one that sees nothing on the network is running whatever the latest GDM in the Debian repositories is.

Gnome/GTK programs slow over XDMCP in Lenny
Hi List, I've been using Debian Etch happily since about October 2007. It's a great, stable environment for the development work I do. After some testing in a virtual machine and on a couple of spare boxes, I decided to move from Etch to Lenny. Unfortunately, I didn't pay enough attention to the speed of Evolution and other GTK programs during my testing. The problem is that I use XDMCP to connect to the server on which my Debian system is running. It seems that GTK programs in Lenny run rather badly. The particular problem seems to be scrolling GTK lists, which is very sluggish (unusably so). I use Evolution as my mail client and scrolling big lists is a major feature of my usage pattern. Scrolling OpenOffice is also a problem (this goes away if I open OpenOffice in KDE). I'm connecting from a Debian 5 computer running an X server to my Debian 5 server. I also tried connecting to a fresh (i.e. not upgraded from Etch) Debian 5 installation running in a virtual machine and demonstrated the same problem. If I connect to an Ubuntu 8.04 virtual machine, performance scrolling GTK lists in Evolution is faster than when connecting to the Lenny OSes and quite acceptable. Ubuntu 8.04 has very similar Evolution/Gnome versions to Debian Lenny, though I believe they are slightly different. So, has anyone else experienced this problem? Does anyone have a workaround? very best regards, Seb James (note - I DO have the RENDER extension on the PC at which I am sitting) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

Re: [gdm-list] connection failed to via xdmcp
Abdelkader: I ve tried to connect to server via XDMCP, (I am using debian lenny with gnome). Following the doc I ve just to enable in gdm.conf , [XDMCP] section, Enable=true. On some machines it ran, on other it didn't ??? If you edit the configuration file by hand, you may need to reboot or restart GDM for the configuration changes to take effect. I'd check that first. You can also turn on enable=true in the [debug] section, restart GDM, and then recreate the problem. Your syslog file (/var/log/messages or /var/adm/messages) should then contain a lot of debug information about what happened, and would be useful to share. Note that you need to enable XDMCP on the machine you plan to connect to, you do not need to enable XDMCP on the client machines. Enabling XDMCP on a client machine does not allow you to log into a machine that doesn't have XDMCP turned on, in other words. I don't know about the gnome-keyring PAM module, or if that is a problem to have missing. Brian -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

A potential 'gotcha' is that, depending on the contents of the file ~/.vnc/xstartup, the VNC server might launch the same window manager that your display manager does. So if you are logged on to your workstation via your display manager you will end up with two copies running. Some window managers and desktop environments don't like that. You can eliminate both of the above problems by quitting X entirely on your workstation and launching VNC from a virtual console. This would represent the simplest test case. -- Liam -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

It should even be possible to run a VNC viewer on your laptop and connect to your workstation in one hop: ssh -L 5901:workstation:5901 server Then you would connect the viewer to localhost:1.

Is it possible? and if so How Sure it is possible, but probably unwise. Using XDMCP involves having the X server (on your laptop) asking the asking a display manager (in this case KDM) on the target host (your home workstation) to open and control the remote server using the X protocol. So to work the way you were doing from home would require opening up the xdmcp ports (177) on your router, and letting the workstation connect to an external X server. If you were using broadcast XDMCP requests, you will probably have to switch to using a specific IP, as broadcasts don't generally work except on a single LAN. In any case, running raw X packets over the Internet is is generally insecure, ant not adviseable. By displaying 'the whole desktop' I assume you mean having the window manager running on your workstation, with the login environment as configured there. You can probably do that via ssh with separate scripts to perform the same environment initialization that you get when logging in the the worstation using XDM. That would have the advantage of keeping the traffic encrypted. You might be able to fool KDM into managing the port forwarded display after establishing your ssh connection - it depends on the capabilities of you X server (I am not familiar with Windows apps like Gygwin/X). It would involve establishing an ssh connection without having a window manager already in control of your server, and adding the port forwarded server to your local managed server list, as the XDMCP wouldn't work. A neater way of being able to do exactly what you do from home would be to establish a VPN connection from the laptop to your home LAN. It takes a bit more configuration, but is secure and once done will give you the same capabilities as when you are at home. However I am no windows expert, so the only way I have done this when someone has wanted to be able to use Windows at the remote end was to use a router with the VPN code built in (in that case, a draytek). Someone else can probably advise what software only options are available for a windows platform. Regards, DigbyT -- Digby R. S.

Help in understanding XDMCP required
In my house, I have two linux machines, both running debian. One, a server, acts as the firewall /gateway between my internal network and the external internet and runs sshd. I have a logon account on this machine. The other is my workstation, and runs KDM to allow me to logon and run KDE. I also have a (work provided) laptop running Windows XP, onto which I have installed Putty and Gygwin/X. When this laptop is on my home network, I can run up a remote session into the KDM logon using XDMCP, and effectively log into my workstation from the laptop. When I am outside my house, this is not possible directly, because of the firewall. I do have an open port, which allows me to SSH (using Putty) from my laptop into my logon account on the server, and I do have X-Forwarding enabled in the sshd on my server machine. I have been able, with a second ssh hop onto my workstation from the server (also forwarding X) to run individual X based applications so that the display is on the laptop, but I can't figure out how to get it to operate so the whole desktop gets displayed there.

I've seen that ssh with X is much slower with the higher overhead (and then extra load for encryption) XDMCP can handle videos in realtime on a 100MBit network, though I've not tested full-screen and you'd then need some way of pushing sound across the network.

XF86Config-4 and XDMCP
Hi all, (Another question, new thread Appreciate all the help as I try to understand Debian and Linux.) I have a machine running Debian Woody that's being used as a server--no keyboard, no mouse, no monitor. I have XDMCP set up so that I can log in to an X session on the machine from another machine on my home network. The question: I want to slim down the machine as much as I can (RAM is limited), and I don't want to load stuff I don't have to. What do I really need in XF86Config-4 for a machine that never has a local display? Another way to put it is, does the video card, monitor, mouse and keyboard information come from the XF86Config-4 on the machine that's logging in? Or the machine that's running X? Perhaps most critically, do I need to have that i810 section with the 8MB of video RAM borrowed from main memory? Thanks, rc Here's XF86Config-4: ### BEGIN DEBCONF SECTION # XF86Config-4 (XFree86 server configuration file) generated by dexconf, the # Debian X Configuration tool, using values from the debconf database. # # Edit this file with caution, and see the XF86Config-4 manual page. # (Type "man XF86Config-4" at the shell prompt.) # # If you want your changes to this file preserved by dexconf, only make changes # before the "### BEGIN DEBCONF SECTION" line above, and/or after the # "### END DEBCONF SECTION" line below. # # To change things within the debconf section, run the command: # dpkg-reconfigure xserver-xfree86 # as root.

I'm not sure about synaptic (does it have to be run as root? if so try investigating xauth to go along), but normally if you've got a working X-server on your local machine and you'd like to run an X-client program from a remote machine you should be able to do so provided you have appropriate permissions. -- Paolo Alexis Falcone [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Gnome XDMCP on server
Hi there, I'm using cygwin-X on my WinXP-Box to access the Gnome-Desktop (2.6) on my Debian-Sarge-Server (Kernel 2.6.7) over XDMCP. My problem is that GDM has to be up and running to login via XDMCP (then it works perfectly well). But - as servers are - I don't have a mouse, keyboard or monitor connected to my server. So GDM crashes after some trying. Is there a way to configure GDM or Xfree86 in any way not to search for a mouse (that's the hanger I guess) ? Or - even better - is there a way to configure GDM for XDMCP not fireing up a local X-Server ? I know there is a thing called X over SSH, but I have many problems to make it work (can't start Synaptic, always get memory errors, can start gnome-session but after that I can't start any prog from Gnome-desktop + many many more issues) and I want to use XDMCP in my personal network only. Any suggestions ? Thank you, Rado -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

VNC's XDMCP requests now fail?
For a while now I've been tunneling VNC over SSH and everythings worked fine. I'd configured inetd to kick off a VNC session on the remote system and restricted to only allow connections from the loopback address. However, I noticed today that this was now broken on several (most) of my systems. The VNC session now immediately terminates on all but one system. After bit of searching I found the following errors in syslog: Sep 3 17:45:34 thor Xvnc[5787]: connect from localhost (127.0.0.1) Sep 3 17:45:35 thor wdm: Cannot open config file. Using builtin defaults Sep 3 17:45:35 thor wdm: X Error of failed request: BadAlloc (insufficient resources for operation) Sep 3 17:45:35 thor wdm: Major opcode of failed request: 45 (X_OpenFont) Sep 3 17:45:35 thor wdm: Serial number of failed request: 50 Sep 3 17:45:35 thor wdm: Current serial number in output stream: 51 Sep 3 17:45:35 thor wdm: Greet: guarenteed_read error, UNMANAGE DISPLAY Sep 3 17:45:35 thor wdm: Greet: pipe read error with /usr/bin/X11/wdmLogin These appear to kick off every time the VNC client attempted a connection and inetd attempted to start the VNC server. I can replicate the errors by running the following command on the remote system: Xvnc -once :1 -query localhost If the -query option is dropped, and thus VNC's XDMCP request, VNC works fine. I've tried switching display managers from wdm to xdm with no change in the error message. I've also tried both tight and real vnc on the remote system without any change in the error. Relevant portions of my configuration files: /etc/X11/wdm/wdm-config: # Don't listen for XDMCP !DisplayManager.requestPort:0 /etc/inetd.conf: vnc stream tcp nowait nobody /usr/sbin/tcpd /usr/bin/Xvnc -inetd -query localhost -once -geometry 1024x768 -depth 24 /etc/hosts.allow: Xvnc: LOCAL /etc/hosts.deny: ALL: ALL Any ideas? -- Jamin W.

XDMCP is roughly as secure as NFS (and arguably less secure), given that it's a plain-text protocol which, among other things, asks for your password when you log in, then sends it across the network. > The only way I can think of doing this would be to start X locally, open > an xterm, log into the server, and run apps from there. > The display would be the client, but the CPU would be the server's. If you're NFS mounting everything an running ot on the client, then you're using the client's CPU. If you want to use the server's CPU, you would ssh to the server (with X tunnelling enabled) and use ssh to tell the server to run it and display on the client's screen. -- The freedoms that we enjoy presently are the most important victories of the White Hats over the past several millennia, and it is vitally important that we don't give them up now, only because we are frightened. - Eolake Stobblehouse (http://stobblehouse.com/text/battle.html) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Connect to the Xterminal from your session host. Export a DISPLAY variable and then merge your xauth token from the session host into the Xterminals ~/.Xauthority file. Here are some details: You are sitting at Xterminal logged into session_host. session_host$ ssh Xterminal Xterminal$ export DISPLAY=Xterminal:0 Make sure that the DISPLAY vars value matches the FQDN listed by `xauth list' on the session host. I don't let my Xterminal ssh to my session host so I do the rest from the session_host, you could do it before ssh'ing to the Xterminal if tha suits you better or allow ssh to the session host. session_host$ xauth extract - $DISPLAY | ssh Xterminal xauth merge - Then you can start xclients on Xterminal and have them make use of the X server running locally. hth, jereme -- +--+ Jereme Corrado <[EMAIL PROTECTED]> System Administrator Restorative Management Corp. gpg: 1024D/9C39E1F0 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Re: XDMCP and client requirements
Here's a related question: Once you are running an XDMCP session on the client, is there any way to invoke an executable on the client machine? Specifically, I want to be able to turn off the screen on the client machine, which can be accomplished by running a special executable on the client. The image I am running locally (based on Midori) came with IceWM pre-configured to run this executable when the user hit the 'power' switch on the keyboard. Makes it behave more like an appliance if you have 'instant-on' and 'instant-off' (so to speak). Another possibility I've considered would be to not use XDMCP but instead NFS mount everything and invoke it from the client. I'm not concerned about NFS security issues because this is just in my house. The only way I can think of doing this would be to start X locally, open an xterm, log into the server, and run apps from there. The display would be the client, but the CPU would be the server's. Any better ways? The main reason I'm considering some workaround is because I'm assuming the problem has to be with the XDMCP connection. -- Bobman -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
