Re: [Ltsp-discuss] Local Device support for multiple workstations?
Hi jam, some general questions about LTSP5: We have numerous thin clients and multiple workstations. So far we use LTSP 4.2 to boot an OS and then use XDMCP to get on the workstations. Users often really need CPU power, so we can not just set up one LTSP server on which everyone works. We wanted to change to LTSP 5. It is much easier to install programs there via chroot. We'd like to have local device support. As far as I know, that does not work with XDMCP because it doesn't use SSH compared to LDM. So the final question: Is there any way to get local device support for multiple workstations and LTSP? This would be great. You're logged in on a workstation via the thin client, plug in the usb device and you can access it from the workstation's OS. It is not that hard to set up direct ltspfs access in a ltsp5 environment. The only trick is to have a coherent dhcp/dns setup in order to have X cookies authentication working (otherwise you can just disable it). You just have to set up properly a few udev rules, a few binaries (ltspfsd, lbuscd, etc.) and startup scripts, and then you have access on what ever ltsp tree you are using (being debian, ubuntu, opensuse, mandriva or whatever) with ldm or not. It would be really great if you could elucidate a bit. Denis every word makes sense, just when you put them all together, me being a bear of little brain (Winnie ther Pooh - AA Milne) gets confused. Please ... sorry, me french, me english not good :-p Jamrs Sorry if I was too confusing. What I wanted to underline is that you can look at ltsp project just as a base framework to make up for what ever thin client setup you want. The framework offer a way to boot a kernel on the network, an initrd, nfsrooting and then a few wisely written script to set up every thing properly. Kernel/initrd twicking is not too hard if you have some kernel compiling background. The only ltsp specific part is mainly to put all the network modules in the initrd file (obviously you need network to get nfsroot) and the nicely written ltsp linuxrc startup script, which in ltsp case takes care of getting network up and nfsrooting (usually network is taken care at init.d stage). Planting and growing a new ltsp tree is the trickiest part. You may install a base system of your choice in a chroot, copy over the ltsp specific binaries (rc.early_sysinit, rc.local, rc.sysinit, rc.localdev, getltspcfg, lbuscd, ltspfsd, ltsp_functions, ltspinfod, lp_server, etc.), some conf file like lts.conf and the ltsp specific udev rules, point the nfs export there, and then fire up a terminal and start debuging to see what is missing and what works. That's a little bit LFS-ish (one can make a pun diverting the acronym and calling it LTSP From Scratch :-), but nevertheless it is very interesting. Once one can get free from prepackaged ltsp and set up one on his own (actually it is the purpose of ltps5 to be distribution centric and not ltsp centric), then solving ltsp terminals issues is like solving issues between two fat clients. In my office we are somehow biased toward MandrivaLinux (yes, we are French...), so one day I just woke up and started to set up a new ltsp tree based on Mandriva distribution for some RD project. In the end it looks like it does work not so bad. When I have time to clean up the thing a little bit, I'll post it somewhere. For Peter : as far as the initial post was concerned, I just wanted to underline that a ltsp client, once boot up, is more or less a standard linux desktop (for debuging you can chroot'aptitude install netstat tcpdump etc.). I'm not sure if the ubuntu ltspfsd binary has been compiled to just listen on the local interface (if it is the case, you can take the one from ltsp4.2, I'm sure it isn't). Otherwise connection/authentication should works in the same way as in ltsp4.2 (ie X cookie auth). I hope I have been a little bit less cryptic.

Re: [Ltsp-discuss] Track and control user bandwidth on LTSP server with 200+ users?
Hi Richard, Yes iptraf is the program I was looking for, I just cannot seem to find any way to make it filter on user ID's. Know of any program that can show me network traffic of each user? No, but that may not mean much. iptraf can tell you which protocols and such are sucking up the bandwidth, and you could configure tcpdump to watch just that traffic. I'm not sure how this would let you isolate individual users in any case. All of the traffic is to or from the server, since the user applications actually run on the server. User is a pretty high level concept for IP-oriented tools like iptraf. using netstat -apn, you can track which pid uses which connection, then piping that information through a ps -edf shoud give you the uid. Hope this help Denis Hope somebody can prove me wrong...

Re: [Ltsp-discuss] LTSP 5 and non-ssh authentication
Hi Rob, I'm trying to set up LTSP 5 on a server that allows ssh access from the internet, and as such I disallow password authentication. This seems to conflict with LTSP 5, though. Is it possible to authenticate by means other than ssh? I use LTSP 4.2 ,disallow password authentication via SSH and restrict the IP addresses from which you can get a SSH connection, and have never had a problem. Is this something new or different with version 5? You can use your /etc/hosts.allow and /etc/hosts.deny files to selectively allow certain addresses to use SSH (and other services). You can also specify allowed users in /etc/ssh/sshd_config I've been using LTSP 4.2 and am trying out LTSP 5. It is different, because (if I understand it correctly) all traffic goes through ssh. There is an option to eliminate the encrypting (through ssh) of all traffic, but my understanding is that it still uses ssh for authentication. In my case I want the same user to be able to log in locally, on a terminal, or from the internet via ssh (text mode). Password authentication would be ok for local and terminal logins, but not for internet logins. I'll probably have to adjust my router to send internet-based ssh requests to a different server, but I was hoping not to. LTSP 5 standard install uses ssh to tunnel traffic from ltsp client to the ltsp server (X protocol itself is not encrypted). The login prompt is not anymore a standard DM called through XDMCP, but a custom made DM called LDM (local display manager). Although, with some quick twicking you can easily go back to the standard X/XDMCP way and forget about SSH. This way you'll be able to configure your ssh server the way you want.

Re: [Ltsp-discuss] LTSP 5 and non-ssh authentication
Hi Oliver, Although, with some quick twicking you can easily go back to the standard X/XDMCP way and forget about SSH. This way you'll be able to configure your ssh server the way you want. note that none of the features (localdev, sound) will work with XDMCP though they require the ssh tunnel to be in place for security... actually X cookie authentication is possible with ltspfs and esd (at least in my custom setup, which is somewhere in between ltsp4.2 and ltsp5, :-). So no problem on this side. However I think tunneling is the only option for securising pulseaudio (it feels good to have sound in sync with youtube video :-p Cheers, Denis ciao oli - Check out the new SourceForge.net Marketplace.

Re: [Ltsp-discuss] About more than one dhcpd-servers
Hi Asmo, I'm going add new server on my office tomorrow. Old one is 32-bit Ubuntu 6.06, new one is 64-bit Edubuntu 7.10. And machine itself is quite upgraded - from P4/1G to Duo Core Xeon/4G. And I hope that it can lives happy with Windows dhcp-server like my old server did: actually you can just use the windows dhcp server as your one and only dhcp server and populate the ltsp specific info into it (cf. https://help.ubuntu.com/community/UbuntuLTSP/LTSPWindowsDHCP). It is not very complicated and works fine, it just feels a little weird :-) I think that it is also possible to explicitly exclude the MAC addresse of the terminals on the windows DHCP server, so you'll be sure that the terminal will get their configuration from the other dhcp server. cheers, Denis This is very interesting. If you don't mind I might ask a question or two. As I understand it, you're relying on the speed of DHCP servers. So, your LTSP dhcp server is faster to respond than the windows one, so it always responds first if it has a static lease defined for a mac address. By contrast, the DD-WRT dhcpd is quick and responds first, which is why it breaks the thin clients. If the linux dhcp server doesn't have a static lease defined, it doesn't respond and the windows server eventually gets used. Have I misunderstood? Is there some other reason the windows dhcp responses don't happen or get ignored? If the above is correct, I imagine placing load on the ltsp server might slow it down and the windows server might respond more quickly than it which might break your clients. Again, if I understand correctly, I guess as long as the dhcp server with the dynamic IP space is the slowest one and the others only respond to their own clients, this should probably work. However, it might be simpler to not run a dhcp server on your new server at all and just add new definitions to the existing edubuntu dhcpd with a different next-server and boot images. This is probably more of a question than an answer I'm afraid :-) Gavin - Check out the new SourceForge.net Marketplace.

Re: [Ltsp-discuss] Suitability - LTSP thin client boot over ADSL VPN
Hi Bill, Hi folks, could I have your views please on the feasibility of an idea I have. We run a central office with approx 30 workstations and 21 remote sites with VPN to central network. These are load balanced over 4 x 8MB ADSL connections so bandwidth is a serious issue. Most of the remote sites only have 1 or 2 workstations installed so because we need to backup we use central file servers further adding to loading. To reduce bandwidth use my thought was to go for a thin client solution but the main problem that I see is that there may not be enough bandwidth to allow for the boot processes. What do those of you who know think of this? Ultimately we want to get all our paperwork web-based so it is all done via https through forms on browsers. We are very small and only have a small development team so I am looking for temporary solutions. On a reliable WAN connection, dhcp is not an issue if you can install a dhcp relay. Kernel + initrd download over WAN can also be ok if you have only ADSL connexion. However in any case you'll get into trouble when mounting remote root NFS. So I don't think the standard ltsp scenario would be a good option for you. If you can mess up with your routers on the remote site, you may install dhcp/tftp/nfs on the router and have the terminal boot localy. This is a no brainer once you have dig a little bit in the boot process of LTSP. Next you'll run into another issue. The X protocol (which is used by LTSP for displaying the session on thin client) has not been designed for high latency network (60ms is tremendously high latency compared to a LAN). One option is to open a nxclient session instead of a gdm/ldm screen. Look for nxrun or better, mess up with ltsp 5 tree, might be easier. However if your purpose is just to use a webbrowser you can just start it as local app. There is even an easier option : if you just have 1-2 station per site, just don't bother with LTSP altogether and install DSL or another specialised embedded distro on a flash drive or usb key.

Re: [Ltsp-discuss] No sound for second login
Hi GentGeen, Thank you Denis for the answer, I was starting to give up :-) If I understand you right, you are refering to the script in the LTSP directory (in my case /opt/ltsp/i386/etc/rc.sound). When I looked at that file, I found (line 66): export ESD_SPAWN_OPTIONS=-public I did try adding -public in the config file for my the server, but that did not help any. That got be wondering if a setting on the servers config file was messing me up. Currently I have esd being launched (at the server) with: you should add the -public option directly in the command line that launch the esd on the thin client (not on the ltsp server), or ack something to get it updated for you : /bin/esd -public -tcp -port 16001 As far as security is concerned, you might prefer not to plug in a microphone (as anyone could access esd on the client and record what you are saying). A cool thing would be to have a X cookie based authentication like ltspfs. Note : there is no issue if it is always the same person login in, so you have to add the -public option only for public workstation. Cheers, Denis /etc/esound/esd.conf [esd] auto_spawn=0 # tried with '-public' but did not help LTSP clients spawn_options=-terminate -nobeeps -as 5 spawn_wait_ms=100 # default options are used in spawned and non-spawned mode default_options= Looking through the 'man esd' I am wondering if I should have auto_spawn=1 or maybe -tcp as one of the options.

Re: [Ltsp-discuss] No sound for second login
Hi gentgeen, I have a problem with sound after the first login. On 2 of my 3 clients, the first login ALWAYS has sound. Sound works great for any and all apps that I have thrown at it. But after that person logs out, the only way to get sound again is to reboot the client. esd has somekind of authentication build in based on cookies, and when the second person log in, the esound server on the thin client refuse the connexion from the sound applications. The only way I found to have it working fine all the time is to add the -public flag in the rc.sound script (look for the line launching esd). It is probably not the most elegant way, but it certainly works. Cheers, Denis Server is Debian Etch (testing). All users are using icesound-experimental -i ESD for the desktop.

Re: [Ltsp-discuss] Setting up hot sync with a cell phone
Hi, I have an interesting dilemma. The company I work for uses LTSP thin clients almost exclusively for workstations. I have a gentleman in our client representative department that wants to use a hotsync to upload contact lists into his cell phone. I was wondering if anyone has had any success in setting this up and if so, how it was done. You first have to check if you can do it with a thick linux workstation (with coldsync, multisync or other). If there are no way the phone can sync with a normal linux, then you'll have a hard time getting it to work with a thin client. There are two issues with synchronizing the phone, first you need some kind of connection, then you need a protocol of communication your contact repository and your phone. There is one standard for sync'ing, called syncml. If your device and your groupware can speak syncml and for transport you can use something simple (like TCP/IP), then the setup could be straight forward. If your device speak a proprietary protocol and your groupware cannot speak with anybody but itself, then it will be tougther.

Re: [Ltsp-discuss] LTSP 4.2 installation concerns
Hi, I currently have a working LTSP (4.1) installation and was about to migrate to LTSP 4.2 just this morning. Here are the steps I took: 1. rpm -ivh http://ltsp.mirrors.tds.net/pub/ltsp/utils/ltsp-utils-0.20-0.noarch.rpm 2. ran 'ltspadmin' , pointed it to /opt/ltsp-4.2 3. installed all of the packages However, upon configuring the services, it gave me this error: [EMAIL PROTECTED] ~]# ltspcfg ltspcfg - Version 0.13 Your ltspcfg version does not seems correct. I though it should be 0.20. Second, when I did my upgrade from 4.1 to 4.2 ltspadmin used the old /etc/ltsp.conf file which pointed to ltsp 4.1 package, so it would not download new 4.2 packages and I had to manually delete /etc/lstp.conf file to get the ltspadmin working. As ltspcfg is concerned, if you have a ltsp 4.1 installation working, you just need to install everything in /opt/ltsp-4.2, copy the old lts.conf file in the new tree, change kernel name and nfs tree name, modify your /etc/exports and it works (no need to run ltspcfg). My first impression are : boot faster, usb device recognition on client side much better, some issues with mounting on terminal side, and couldn't find a suitable perl-protocol-X11 for my mandriva 2006 yet (but manually calling ltspfs works fine in command line, when device is correctly mounted).

Re: [Ltsp-discuss] problem with local dev
Hi michael, I need support for local harddrives, this is not in the sense of a thin client but needed in my case. Will ide hard drives be supported from 4.2? I did not find a hint in the docs. Thanks a lot Michael ltspfs is just a network file export with X11 authentication. It exports the /tmp/drives on the client side. If you can hack the rc script for mounting your local ide on /tmp/drives/localide then it's ok (it is perhaps already included though). So that shouldn't be an issue. Go for 4.2.

Re: [Ltsp-discuss] Sleep on LAN or Ether-halt?
Hi, Has anyone written a program to cause a system to sleep/halt/reboot by sending it a TCP or UDP command? I would like it to be along the same lines as ether-wake, a simple C or C++ program that is small and does not use a lot of libraries. I need this for my terminal network. I have been using a simple bash script that all terminals just read the contents of a file on the NFS server. When they see their MAC address the terminal shuts down. This is a simple bash script but only works with terminals. I am going to need a sleep on LAN program that will work with other systems also. I will write one if there is not one yet. For the non-terminals (full-blown Linux boxes), installing the ssh server should be sufficient. Have a no-power-user there, allow it to run shutdown with sudo (but without password), enable public-key-cryptography (which is not difficult... there are lots of howtos out there) and then something like this works for thin client too. The ssh deamon is already included in ltsp nfs tree, it just needs to be configured. I've been using this method for automatically shutting down thin clients for more than 6 months in classrooms and it works fine. For Windows 2k/XP-machines, you could enable telnet (**ugly**), and instlal command-line tools for shutdown. There is a toolset with a name like psutils or so, containing a psshutdown.exe (?) that could be called from the login prompt you get into with telnet. ssh may also help you there. Cygwin installs and works like a charm (at least for the basic task I needed). It bundles a ssh server which works fine (you can do ssh key exchange, etc.) and there is probably something like the shutdown command.

Re: [Ltsp-discuss] client's floppy or usb
Hi, http://wiki.ltsp.org/twiki/bin/view/Ltsp/LocalMedia or http://www.unicolet.org/linux/ltsp.html Since you are starting from scratch you could try ltspfs which is reported to work very well. Hi! I just ran into this for setting up my USB device on LTSP. One of these says I need SMB and the other says KDE. And what do I get to do if I have neither? (no SMB because I have nothing in Windows in my network) (no KDE because I only use WindowMaker) To access usb keys (or other storage devices) on terminal, you need some kind of mounting/unmounting system on the terminal (automount, supermount, etc.), and a way to access that remote directory from the ltsp server. The SMB / KDE-kioslaves examples you mentions are just a way to access the remote directory. You may try any other way, like scp, ftp, emule, etc. The main issue with all those methods is authentication, since the only way to know who can access the local devices is to know who is currently connected to the terminal. The LTSP team is currently setting up a fuse module (ltspfs) that can access local share using X cookie for authentication.

Do you know if there has been in progress in the Debian installation which might change the accuracy of these specific docs? it is quite standard. Just get fuse working (you may test your installation with a sshfs or fusesmb fuse sub-system). If it is not packaged for your distrib, then compile it. Then compile your ltspfs and ltspfsd. Gcc and fuse header should do it. Be sure to set up your dhcp/dns correctly and that your terminal get an hostname (check by typing the hostname command on the terminal). That's actually the trickiest part. I am thinking this would be definitely worth trying. your definetly right. Now for a dumb question. Can fuse work with the local hard drive as well? ltspfs give an authenticated network access to a directory on the thin client.

Re: [Ltsp-discuss] LTSP with FreeNX
Hi Lonnie, So in what situation would you want to use LTSP with FreeNX together? FreeNX may be a good option if you have to be carefull about your bandwidth consumption and latency (500Kbps for a ltsp terminal, down to 100Kbps or less for a NX terminal) . Moreover FreeNX encrypt by default all traffic in an ssh tunnel, so if you need tight security, that a good option. Would it be that FreeNX is used just like VNC so that someone with a Windows machine could access the LTSP server in a similar way that VNC allows for you to do? NX and VNC are different. When you start a NX session you get a brand new session (or reactivate a suspended one). With VNC, you connect to an existing XServer. NX currently cannot share a session. NX protocol is based on X, which is unix-like specific. VNC has it's own protocol and has been implemented for about any existing platform. You may hack the init script on the terminal to integrate the nxclient. Or perhaps someone has already done it. I usually use both X (normal ltsp configuration) and NX on lstp server. This way people with Windows/MacOsX laptop can connect to the ltsp server either from local network or from home. My guess would also be that if this is the case are there FreeNX client software similar to VNC as well? There are NX client available for windows/MacOsX/Linux from the nomachine.com site.

You can set up your own command line client or use free graphical one like knx. You may check that wiki page : http://wiki.ltsp.org/twiki/bin/view/Ltsp/WorkInProgress#NX Cheers, Denis Sincerely and have a good day, Lonnie T. Cumberland OutStep Technologies Incorporated Email: [EMAIL PROTECTED] [EMAIL PROTECTED] Recommended sites: http://www.peoplesquest.com and http://www.worldlinktelcom.com Quoting Denis Cardon [EMAIL PROTECTED]: Hi Lonnie, So in what situation would you want to use LTSP with FreeNX together? FreeNX may be a good option if you have to be carefull about your bandwidth consumption and latency (500Kbps for a ltsp terminal, down to 100Kbps or less for a NX terminal) . Moreover FreeNX encrypt by default all traffic in an ssh tunnel, so if you need tight security, that a good option. Would it be that FreeNX is used just like VNC so that someone with a Windows machine could access the LTSP server in a similar way that VNC allows for you to do? NX and VNC are different. When you start a NX session you get a brand new session (or reactivate a suspended one). With VNC, you connect to an existing XServer. NX currently cannot share a session. NX protocol is based on X, which is unix-like specific. VNC has it's own protocol and has been implemented for about any existing platform. You may hack the init script on the terminal to integrate the nxclient. Or perhaps someone has already done it. I usually use both X (normal ltsp configuration) and NX on lstp server. This way people with Windows/MacOsX laptop can connect to the ltsp server either from local network or from home. My guess would also be that if this is the case are there FreeNX client software similar to VNC as well? There are NX client available for windows/MacOsX/Linux from the nomachine.com site.

They're actually not. LTSP will boot a thin client: FreeNX won't. Think of NX as a super-duper-crazy-fast upgrade to VNC. They're not exactly the same, but the overall concept is. Also, when would you use them together? 1. LTSP over a WAN. Boot locally, but work globally (TM). :) 2. Session saving. Can't do that with plain old XDMCP. There are many more reasons, but that's it from me. I hope that helps some.
