Questions[ltsp](server)

A standard xinit command looks like this:

xinit /usr/local/bin/app -- :1 vt2

However, I have a command that looks like this:

xinit /usr/bin/xfreerdp -a 16 -u '' -x m -z --disable-wallpaper --disable-full-window-drag --disable-menu-animations --disable-theming --plugin rdpsnd --plugin rdpdr --data disk:Devices:/media/root -- 10.0.0.197 -- :1 vt2

Notice how the command given to xinit uses "--" in-and-of-itself (before the IP)? Well, xinit complains about it:

Fatal server error:
Unrecognized option: 10.0.0.197

How do I get xinit to allow the use of a "--" within the command given to it?

Please note that I thought about moving the sub-command to it's own bash script, but this is for an LTSP server.

I have some recent HP thin clients, and Linux supports 3D acceleration on this hardware.

I have played with LTSP and GNOME 2. I am new to the world of thin clients, and I understand that GNOME 3 requires hardware accelerated client side OpenGL to work well.

How would I best go about getting GNOME Shell to run on a capable thin client as a local app, while launching other apps on the server as normal?

After my ltsp-build-client --arch i386 All went well, but for some reasons tftpd-hpa wasn't installed there were no /var/lib/tftpboot folder.

So I had to install tftpd-hpa manually. DHCP is working well but it can't find pxelinux.0 file (it just doesn't exist).

Here is my DHCP server conf.

authoritative;

subnet 10.10.10.0 netmask 255.255.255.0 {
    range 10.10.10.20 10.10.10.250;
    option domain-name "example.net";
    option domain-name-servers 10.10.10.1;
    option broadcast-address 10.10.10.255;
    option routers 10.10.10.1;
    option subnet-mask 255.255.255.0;
    option root-path "/opt/ltsp/i386";
    if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
        filename "/ltsp/i386/pxelinux.0";
    } else {
        filename "/ltsp/i386/nbi.img";
    }
}

client machines are saying:

PXE-T01: File not found
PXE-E3B: TFTP Error - File Not Found

PXE-MOF: Exiting Intel PXE ROM.

The question: How to generate the pxelinux.0 file and/or nbi.img file? There is image though in /opt/ltsp/i386/images/i386.img But I'm not sure what's that image for.

TFTP Server is running by: /usr/sbin/in.tftpd --listen --user tftp --address 0.0.0.0:69 --secure /var/lib/tftpboot

the /var/lib/tftpboot folder is empty.

Or another question. How to Generate pxelinux.0 and nbi.img file again?

I'm using LTSP on a Ubuntu 10.04 64bit box with 8 thin clients.

I would like to save power by automatically turning off the thin clients at night, but I would like to have the ability to resume the staff's session in the morning.

Is it possible to keep a session running whilst turning off the LTSP thin client and resuming that session when you power up the thin client the next time?

Could this work if you login to another thin client in the morning and resume your session?

I have attempted to install CUPS on an LTSP fat client. Both the client and the server are running Ubuntu 9.10 and cups runs fine on the server. When I try to start it on a client I get this:

root@ltsp52:~# service cups start  
* Starting Common Unix Printing System: cupsd  
/usr/sbin/cupsd: error while loading shared libraries: libcupsmime.so.1:  
cannot open shared object file: No such file or directory  
                                                                     [ OK ]  
root@ltsp52:~#

libcupsmime.so.1 exists in /usr/lib/libcupsmime.so.1 (the same place it exists on the server). I'm not quite sure what I am doing wrong, but the problem is becoming quite frustrating and any help would be greatly appreciated.
