| 08:19 | <dnaf[working]> hi there. I have Debian Sarge 3.0 and KDE 3.0, when I log on using diskless workstation, there are no any keyboard settings. and, as a result, no layouts except en-us.
| |
| 08:22 | if you have any ideas about it, please e-mail me to dan @ idex.ru

| |
| 08:46 | <envite> Most of it is usable in 4.2

| 10:23 | <cstextiles> Limit UserId Login to one LTSP Client.i.e. I require that a particular user can login through only one LTSP Client i.e. Suppose I have a network of 10 PCs then the user can login only from Hardware Machine A and cannot do it from Machine B.Is that possible?
| |
| 10:26 | bobby_C has joined #ltsp | |
| 10:28 | <pscheie> cstextiles: it's crude, but could you put something in UserID's .profile that checks the workstation number and if it doesn't match does a pkill?
| |
| 10:29 | <cstextiles> pscheie: How to get the workstation no?
| |
| 10:30 | pscheie: Workstation depends on the MAC No Am I correct and so can identify the PC properly Am I correct?
| |
| 10:31 | <pscheie> you can hardcode an IP address to a particular MAC address in dhcpd.conf
| |
| 10:31 | then check, say, $LTSP_HOSTNAME
| |
| 10:32 | cstextile1 has joined #ltsp | |
| 10:33 | <cstextile1> pscheie: I m sorry but some internet problem The last msg i rcd is "you can hardcode an IP address to a particular MAC address in dhcpd.conf"
| |
| 10:33 | <sbalneav> cstextile1: That would be fairly easy to do.
| |
| 10:34 | <cstextile1> pscheie: Ya that i got it how to get the workstation no in the .profile to compare it with the allowed workstation no
| |
| 10:34 | <sbalneav> You could just add an /etc/X11/Xsession.d/mumble file to check if the users's already logged on, then just call exit if they are.
| |
| 10:34 | <jammcq> sbalneav: SCOTTY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
| |
| 10:34 | <sbalneav> hey hey
| |
| 10:34 | * jammcq wonders when sbalneav snuck in | |
| 10:35 | <pscheie> sbalneav: He want's to limit a user ID to a specific tc
| |
| 10:35 | *wants
| |
| 10:35 | <cstextile1> sbalneav: Ya pscheie: said it right
| |
| 10:35 | <pscheie> so if he does
| |
| 10:36 | if [ $LTSP_HOSTNAME != ws001 ]; then
| |
| 10:36 | pkill -u user1
| |
| 10:36 | fi
| |
| 10:36 | (haven't tried this)
| |
| 10:37 | I suggested putting that in user1's .bash_profile, but there's probably a better place to check it,
| |
| 10:37 | farther upstream so it checks sooner in the login process
| |
| 10:39 | <cstextile1> Ya Is there any tool so that i can put it it after the login process concludes?
| |
| 10:40 | <pscheie> I just tried putting it in ~user1/.bash_profile and it works as desired
| |
| 10:40 | user1 tries to login elsewhere and just gets dumped back to the login screen
| |
| 10:41 | ogra has joined #ltsp | |
| 10:41 | <pscheie> but on ws001, user1 can login
| |
| 10:42 | sepski has joined #ltsp | |
| 10:42 | <cstextile1> so this .bash_profile is the file which is executed when the user logs in the Am I correct? and the path for the same /home/user1/.bash_profile in Ubuntu? Am I correct
| |
| 10:43 | <pscheie> yes on the first question; I think Ubuntu has .bash_profile, although I'm looking at a Fedora system
| |
| 10:43 | can any Ubuntu users confirm the existence of ~/.bash_profile?
| |
| 10:44 | or perhaps ~/.profile?
| |
| 10:44 | .bash_profile might be a RH thing
| |
| 10:44 | * pscheie wonders why all distros don't just use .profile, in the unix tradition | |
| 10:46 | <cstextile1> I think it is at /etc/profile according to this URL though the path for different users remains a question or can't understand http://ubuntuforums.org/showthread.php?t=969 ?
| |
| 10:48 | <pscheie> /etc/profile is used by all users, you don't want that
| |
| 10:48 | you only want user1's login to check
| |
| 10:49 | <cstextile1> pscheie: Ya that what I asked I am trying to find the path for a single user?
| |
| 10:49 | <pscheie> although I suppose you could check the ID and check the WS # and if they both don't match correctly, do a pkill
| |
| 10:49 | and put that into /etc/profile
| |
| 10:49 | /etc/profile is for all users
| |
| 10:49 | cstextiles has quit IRC | |
| 10:49 | <cstextile1> pscheie: One minute how to check the userid entered?
| |
| 10:49 | <pscheie> each user's ~/.profile or .bash_profile is for just that user
| |
| 10:50 | <cstextile1> i mean for workstation no it is $LTSP_HOSTNAME but for UserId ? what is the variable?
| |
| 10:50 | <pscheie> do an 'ls -a' in user1's home directory first, see if there's a .profile or .bash_profile
| |
| 10:51 | <cstextile1> I am currently not in a Ubuntu machine as I have that unconnected Internetless machine in a differnt location so can't check that now but as far as i remmber there is no such file?
| |
| 10:52 | <pscheie> $LOGNAME or $USER should contain the user ID
| |
| 10:52 | well, since it begins with a dot (.) it's a hidden file, so you won't normally see it
| |
| 10:53 | ls -a means show ALL files
| |
| 10:53 | <cstextile1> ok so that must be the reason. Now i got that ok I will see those files and I think it must be in the home directory?
| |
| 10:53 | <pscheie> or there's a setting somewhere in Nautilus to display hidden files, but I think it's turned off by default
| |
| 10:54 | yes, in each user's $HOME there should be a .profile or .bash_profile
| |
| 10:54 | <cstextile1> pscheie: Nautilus is like Windows Explorer? Am I correct
| |
| 10:54 | <pscheie> yes, it's the file manager
| |
| 10:54 | <envite> cstextile1: it's more than Windows Explorer
| |
| 10:54 | ;)
| |
| 10:55 | * pscheie agrees with envite | |
| 10:55 | <envite> but I (personally) prefer Konqueror
| |
| 10:55 | kioslaves do a great job
| |
| 10:55 | <cstextile1> pscheie: I got that I have used that but did not know what it is called.
| |
| 10:55 | <envite> I use fish:// almost every day
| |
| 10:55 | <cstextile1> envite: Konqueror comes with KDE GUI Am I correct?
| |
| 10:56 | envite: I had seen it in KNoppix system
| |
| 10:56 | <envite> cstextile1: it comes included in KDE, but you can install it alone in a Gnome system
| |
| 10:56 | <pscheie> One can run konq under gnome if both environments are installed
| |
| 10:57 | <envite> simply aptitude install konqueror or urpmi -i konqueror or the one for your distro
| |
| 10:57 | <cstextile1> Can anyone has any comparasion link beteween both the system displaying the pros and cons comparasion
| |
| 10:58 | <envite> cstextile1: i think any one you can found will be non-neutral
| |
| 10:58 | <cstextile1> envite: Ya but atleast will shed more light to any one System?
| |
| 10:59 | <pscheie> both work well but differently--it's mostly a matter of personal preference
| |
| 10:59 | <envite> cstextile1: just a question
| |
| 11:00 | cstextile1: do you ask a Windows-Linux comparison or a KDE-Gnome one ?
| |
| 11:01 | <cstextile1> envite: KDE-GNOME
| |
| 11:01 | <envite> ok
| |
| 11:02 | cstextile1: well, the main difference is that KDE is highly integrated and polished, but big, slow and very interdependent between its pieces
| |
| 11:02 | Gnome is not so polished and integrated, but light and fast, and most pieces can be used independently
| |
| 11:03 | gigabytes has joined #ltsp | |
| 11:03 | <envite> actually both of them are working towards better interoperatibility
| |
| 11:04 | * ogra would say exactly the opposite :) | |
| 11:04 | <ogra> i guess it totally depends on your personal preference ... i find gnome far better integrated
| |
| 11:04 | and way more polished :)
| |
| 11:05 | <cstextile1> can anyone explain me the defination of polished and integrated with examples to shed more light?
| |
| 11:05 | <pscheie> depends on the day of the week for me; some days I love one and curse the other, the next day it can flip
| |
| 11:05 | <ogra> cstextile1, i'd suggest to download a kubuntu and a ubuntu desktop CD, compare them and make a decision for yourself
| |
| 11:05 | <envite> pscheie: totally agree
| |
| 11:05 | <pscheie> I think it's very dependent on how the user thinks about things
| |
| 11:06 | <ogra> right
| |
| 11:06 | and what you are used to
| |
| 11:06 | <pscheie> and one way isn't necessarily better than the other
| |
| 11:06 | people are just wired differently
| |
| 11:06 | <envite> an example of tight integration is kontact with kmail, kgpg, etc
| |
| 11:06 | <pscheie> I try to be ambidextrous
| |
| 11:06 | <ogra> envite, thats what evolution does in gnome as well :)
| |
| 11:07 | i think you find examples for everything in both desktops if you know where to look
| |
| 11:07 | <envite> evolution integration is not so tight
| |
| 11:07 | IMHO
| |
| 11:08 | <pscheie> sometimes integration isn't helpful
| |
| 11:08 | <ogra> well ... it integrates with gnome-keyring-manager, evolution-data-server (calendar and adressbook stuff) and is a mail client ...
| |
| 11:08 | <cstextile1> so tight? can you please eloborate
| |
| 11:09 | <pscheie> I discovered yesterday that launching nautilus manually briefly creates a PID for nautilus
| |
| 11:09 | <ogra> i dont see a difference to integrating kontact ,kmail and kgpg
| |
| 11:09 | <pscheie> but then the PID goes away even though nautilus is still running
| |
| 11:09 | and I need to kick off something after the file manager is closed, so tracking that by PID won't work
| |
| 11:09 | but calling konq may work
| |
| 11:10 | since it isn't integrated
| |
| 11:10 | <ogra> cstextile1, really, grab a distro that offers two liveCDs of both desktops with the same OS underneath and try them
| |
| 11:10 | * pscheie admits this is an obscure example | |
| 11:10 | <ogra> this way you can make sure to only see the difference in desktop handling
| |
| 11:10 | install the one you like more then :)
| |
| 11:11 | <cstextile1> ogra: Ya I got that
| |
| 11:11 | * ogra goes back to implementing cairo in ldm ... | |
| 11:12 | <sbalneav> Meh, gnome, KDE, they're all too big. Just use TWM, and do everything in Xterms :)
| |
| 11:13 | <envite> sbalneav: therea re things you can't do in an xterm
| |
| 11:13 | <sbalneav> I mean really, between lynx and mutt, there's your mail
| |
| 11:13 | <envite> like looking at films
| |
| 11:13 | <pscheie> sbalneav: You get to use a window manager? Luxury!
| |
| 11:13 | <sbalneav> Phht, films? Who needs those?
| |
| 11:13 | <envite> sbalneav: me
| |
| 11:13 | <pscheie> films should be viewed in vi as God intended
| |
| 11:13 | * jammcq wants to someone actually book an airline ticket using links/lynx | |
| 11:13 | <envite> sbalneav: I like ancient films
| |
| 11:14 | <jammcq> s/wants to/wants to see/
| |
| 11:14 | <cstextile1> Yes Can we limit the user from opening the File Manager for the home directory only? I mean he cannot see other folders or read the contents of the root or any other directory?
| |
| 11:14 | * sbalneav dials phone | |
| 11:14 | <sbalneav> "hello, NW? I'd like to book a flight!" :)
| |
| 11:14 | <jammcq> phone? that's SOOOO 1990's
| |
| 11:14 | * jammcq doesn't like to actually have to talk to anyone (ever) | |
| 11:16 | <ogra> sbalneav, envite, mpayer has an asciiart output plugin ...
| |
| 11:16 | *mplayer
| |
| 11:16 | <envite> jajajajajajajajajajajajaja
| |
| 11:16 | <pscheie> cstextile1: why do you need to prevent user1 from looking at other directories?
| |
| 11:16 | they're read-only
| |
| 11:17 | <envite> I CAN'T imagine viewing Matrix in ASCII-art
| |
| 11:17 | <pscheie> I can imagine viewing Star Wars in ASCII-art 'cause I've done it
| |
| 11:17 | <sbalneav> Yeah, works great.
| |
| 11:17 | Actually, I think the film's BETTER that way :)
| |
| 11:18 | <envite> jejejejeje
| |
| 11:18 | <cstextile1> pscheie: There are certain programs which I want to restrict the user to copy from the folder though he can run the said executable but can't copy that executable
| |
| 11:18 | <jammcq> help me obi-wan kenobi, yer my only hope
| |
| 11:19 | <bricode> very Matrix-esque.
| |
| 11:20 | You get *way* better compression using ASCII-art as your video source.
| |
| 11:20 | :)
| |
| 11:20 | <jammcq> yeah, but it's just a bit "lossy"
| |
| 11:21 | <envite> huh, not "a bit"
| |
| 11:22 | <bricode> http://www.youtube.com/watch?v=876jZuLhsbU
| |
| 11:23 | Has anyone solved the fat client using NFS timeout issue?
| |
| 11:24 | Would it be better (although you'd take a hit) to use TCP for NFS?
| |
| 11:24 | Are there alternatives to NFS for handling fat clients?

| |
| 14:09 | <ogra> sbalneav, i was thinking about bumping the version number of the ubuntu package to 5.something ...
| |
| 14:09 | <sbalneav> Yes.
| |
| 14:09 | 5.1 at least.
| |
| 14:10 | <jammcq> should be fun, we'll have 4.2, 5.0 and 5.1
| |
| 14:10 | <ogra> well, i was thinking 5.0.1 so we are more flexible
| |
| 14:10 | <jammcq> yeah, that would be better
| |
| 14:10 | it would still conform to the "5.0" spec
| |
| 14:11 | <ogra> right, we should wait with 5.1 :)
| |
| 14:12 | to avoid a chaos
| |
| 14:13 | <sbalneav> Surly

| |
| 14:14 | <sepski> are there any notes/docs on how to implement/test it ?
| |
| 14:14 | <ogra> "don't call me surly"
| |
| 14:14 | <jammcq> heh, that's a "North american" thing :)
| |

| |

| |
| 14:15 | <sbalneav> Surly = mean/miserable, surely = certainly
| |
| 14:15 | <jammcq> vs Shirley, a girls name
| |
| 14:15 | <mistik1> haha

| 14:15 | <ogra> you would have to grow your hair longer for that
| |
| 14:15 | <jammcq> heh, MUCH

| 14:20 | <ogra> yeah, nice idea for a tutorial /me thinks :)
| |
| 14:20 | * jammcq agrees | |
| 14:20 | <pscheie> bah! the clock is fast
| |
| 14:20 | <ogra> i'm digging through python docs the whole day, thats refreshing
| |
| 14:21 | * pscheie ducks | |
| 14:21 | <ogra> well, its wrong as well ...
| |
| 14:21 | <jammcq> it's right twice a day
| |
| 14:21 | Skarmeth has joined #ltsp | |
| 14:21 | <jammcq> maybe for 120 seconds each day
| |
| 14:22 | <ogra> heh
| |
| 14:23 | <mistik1> Guys I want to just air some things so I know i'm grasping this ltsp5 framework....
| |
| 14:25 | I see a bunch of modules in launchpad and so far it seems you simply split them into different installable packages which then gets installed either in the server's rootfs or the workstation chroot ....
| |
| 14:25 | <ogra> where are you looking exactly ?
| |
| 14:25 | <mistik1> Each package has a set of deps that may pull in other packages into the respective rootfs
| |
| 14:26 | <ogra> there are three packages: ltsp-server, ltsp-server-standalone and ltsp-client
| |
| 14:26 | <mistik1> ogra: so far I've looked at the feisty-mainline ltsp-mainline and ltspfs
| |
| 14:26 | <ogra> ltsp-server sets up tftp and nfs for you and installs three maintainer scripts
| |
| 14:27 | feisty-mainline and ltsp-mainline are the relevant ones ... i'm currently doing development in feisty-mainline and snyc the work back to ltsp-mainline
| |
| 14:27 | ltsp-mainline is the merged tree of debian and ubuntu
| |
| 14:28 | <mistik1> hmm
| |
| 14:29 | <ogra> one of the maintainer scripts is ltsp-build-client ...
| |
| 14:29 | if you run it, it bottstraps a system in /opt/ltsp/<arch>, installs X, ldm and the ltsp-client package in there ...
| |
| 14:29 | <mistik1> can you explain what those other two packages contain and where they get installed
| |
| 14:30 | ahh
| |
| 14:30 | <ogra> the ltsp-client package installs two initscripts ....
| |
| 14:30 | one to autoconfigure an ltsp client
| |
| 14:31 | and one that starts the screen scripts (by default ldm)
| |
| 14:31 | the third package, ltsp-server-standalone just depends on ltsp-server and dhcpd, so you get a standalone server out of the box with this package
| |
| 14:32 | <mistik1> so that is just a meta package?
| |
| 14:32 | <ogra> right, only two dependencies
| |
| 14:32 | <mistik1> *nod*
| |
| 14:33 | <ogra> ltsp-server is only three scripts and some setting changes ...
| |
| 14:33 | ltsp-client is two initscripts ...
| |
| 14:33 | the important part of ltsp5 is ltsp-build-client
| |
| 14:33 | (codewise)
| |
| 14:34 | <mistik1> what installed the plugins and all that
| |
| 14:34 | <ogra> the plugins are what ltsp-build-client is ...
| |
| 14:35 | <mistik1> excellent!
| |
| 14:35 | <ogra> the script itself is very basic and pretty distro indeendent ...
| |
| 14:35 | then we have a set of common plugins in the common dir ...
| |
| 14:35 | <mistik1> I get that part
| |
| 14:35 | <ogra> these currently are the plugins common between debian and ubuntu, but should be distro independent as well ...
| |
| 14:35 | <mistik1> I was just wondering how it was all packaged in the end
| |
| 14:35 | <ogra> and last you have your distro specific subdir
| |
| 14:37 | <mistik1> thanks ogra
| |
| 14:37 | <ogra> youre welcome :)
| |
| 14:38 | Blinny has quit IRC | |
| 14:38 | <mistik1> I've not dealt with the idea of packages (the way debian considers then) in some time
| |
| 14:40 | dberkholz has done a nice job o laying out what would be needed for the gentoo plugin..
| |
| 14:40 | <ogra> great
| |
| 14:40 | <mistik1> jammcq: Thanks, I was in a bad mood yesterday but this looks like its a nice way to go
| |
| 14:40 | <ogra> would be great to finally see more distros adopt it
| |
| 14:41 | i'm not sure where the redhat port stands
| |
| 14:41 | it looked most promising, but got most quiet as well
| |
| 14:41 | <mistik1> ogra: I took me a while to get my head around why I need a build system for an OS that uses a build system to install everything
| |
| 14:42 | <ogra> heh
| |
| 14:42 | if you do debian development you do that every day ... since ages :)
| |
| 14:42 | chroots are great for testing and package development
| |
| 14:42 | <mistik1> yep
| |
| 14:42 | i do it all the time
| |
| 14:43 | for example this machine it an x86_64 so everything I do that is x86 I have to do in a chroot
| |
| 14:43 | linux32 chroot /foobar and away we go
| |
| 14:44 | I cant be bothered to crosscompile
| |
| 14:44 | It should be renamed to the 7 headed monster of programming

| 14:50 | <steven43126> hi
| |
| 14:51 | what kind of bandwidth would your require for say 30 users, to have a reliable interactive session ?
| |
| 14:52 | is gigabit link between the server and switch fine, and all the clients on 100MB connections ?
| |
| 14:52 | <pscheie> steven43126: should be enough, depending on the apps the users are running
| |
| 14:54 | <steven43126> pscheie, how many users can a gigabit connection support ?
| |
| 14:54 | <pscheie> depends on the apps
| |
| 14:54 | <steven43126> say openoffice,email + firefox on average ?
| |
| 14:55 | <pscheie> but if you've got a good gig card in a pcix (or is it pcie?) slot, you should be able to handle ~40
| |
| 14:55 | assuming the server can handle that many users
| |
| 14:55 | use iptraf to check the network utilization
| |
| 14:56 | If you're machine has multiple pcix slots, you could add another gig card
| |
| 14:56 | and either bond them or use different subnets
| |
| 14:56 | cliebow has quit IRC | |
| 14:57 | <steven43126> pscheie, is there anyway to cheat with video streaming to clients, if they must use video, is there a workaround ?
| |
| 14:57 | <pscheie> of course, if your users are hitting a lot of Flash websites, you may hit the ceiling sooner than 40 users
| |
| 14:58 | <steven43126> pscheie, why diff subnets if i have a good quality switch shouldn't i just be able to use a diff Ip for the other card ?
| |
| 14:59 | <pscheie> well, you can do bonding
| |
| 14:59 | but without that or separate subnets, I think you have some routing problems
| |
| 15:00 | <steven43126> im thinking of maybe using NX instead, i think the bandwidth requirements are alot less
| |
| 15:00 | looks like ill have to set both up and run some tests
| |
| 15:00 | <pscheie> nx from the client to another server?
| |
| 15:01 | <steven43126> instead of using LTSP maybe just run nxserver, an nx clients on the client machines
| |
| 15:01 | im not sure but i think nx uses less bandwidth
| |
| 15:01 | <sepski> steven43126, nx uses significantly less bandwith, and significantly more cpu
| |
| 15:01 | <pscheie> you can, but then you still have to manage the clients' OS
| |
| 15:02 | <sepski> steven43126, adds a little latency
| |
| 15:02 | <pscheie> and you need a heftier processor in the client
| |
| 15:02 | <sepski> so if you have a 100mbit network and you dedicate it for thin clients you can run ~40 if they dont do video or similar
| |
| 15:02 | <steven43126> hmm, i suppose im going to have to run some benchmarks
| |
| 15:02 | <pscheie> OTOH, if you've already got your clients and their CPU are 1ghz+, it might work
| |
| 15:03 | yes, do some benchmarking; as always, the answer is 'it depends' ;-)
| |
| 15:03 | <sepski> steven43126, if your clients are 1ghz you can run them as diskless clients
| |
| 15:03 | <steven43126> NX really need that much cpu power ?
| |
| 15:04 | yes i was thinking of just using a cut down linux with the nxclient installed, and boot over pxe
| |
| 15:04 | but i did not realise NX was Sooo cpu intensive
| |
| 15:04 | <sepski> it's not SOOO cpu intensive, but most fanless thin clients have ~500 mhz cpu's downclocked to 200 mhz
| |
| 15:05 | <pscheie> that's just a guess
| |
| 15:05 | <sepski> and on such boxes it's noticeable
| |
| 15:05 | <pscheie> you could try, say, damn small linux and see if the nx client will install on it
| |
| 15:05 | <sepski> on a 100mbit network regular ltsp is faster/more responsive then nx.
| |
| 15:05 | <pscheie> actually, isn't there a PXES liveCD that contains an NX client?
| |
| 15:06 | <sepski> on a slower linke nx is nice
| |
| 15:06 | * pscheie agrees with sepski | |
| 15:06 | <steven43126> sepski, could you reccomend a thinclient that supports bootin custom images over pxe for me to test with ?
| |
| 15:06 | <pscheie> nx is a good alternative to vnc
| |
| 15:07 | Skarmeth has quit IRC | |
| 15:07 | <steven43126> nx is good on slowr links which got me thinking if i have 30 + users maybe NX would allow me a more responsive session, less data to handle
| |
| 15:08 | <sepski> steven43126, no the compression adds latenct compared to stright X11
| |
| 15:09 | <steven43126> sepski, yes is suppose i assumed at 30 users + the cost of compression would be minimal compared to the bandwidth requiremetns of LTSP
| |
| 15:09 | <sepski> what network speed do you have ?
| |
| 15:09 | <steven43126> 100mb switch which clients are connected to
| |
| 15:09 | <sepski> i usualy run 40 clients on a 100 mbit switch before bothering to split it on separate networks
| |
| 15:09 | <steven43126> which has a gigabit link to a gigabit switch
| |
| 15:10 | <sepski> we have 60 on one, but there is not all 60 online at the same time
| |
| 15:10 | we only have 100 mbit to the server
| |
| 15:10 | <steven43126> where the servers are plugged into
| |
| 15:10 | sepski, how many would you say are online at once ?
| |
| 15:10 | <sepski> i have a rule of thumb of 2mbit /cleient on regular desktop work
| |
| 15:10 | ~40
| |
| 15:11 | + overhead means i usualy dont want more then 40 on a 100 mbit switch
| |
| 15:11 | str4nd has quit IRC | |
| 15:11 | <steven43126> hmm looks like ltsp may be the way to go then
| |
| 15:11 | Megant_ has quit IRC | |
| 15:12 | jammcq has quit IRC | |
| 15:12 | <sepski> you can just install the nxclient in the ltsp chroot and use ltsp to boot the client, but run nxclient instead of ldm to connect to the server.
| |
| 15:12 | but unless you have a slow link it's going to worsen performance
| |
| 15:13 | <steven43126> sepski, thanks yes sound right, i was under the impression using less bandwidth would give me better performance
| |
| 15:13 | <sepski> steven43126, when bandwith is taxed yes ofcourse.
| |
| 15:13 | if you have a 2mbit tokenring network with 30 clients :)
| |
| 15:14 | but since you have uber plenty network you dont have to wory
| |
| 15:14 | <steven43126> sepski, i ran some tests i while ago using xdmcp and i was getting network peaks of 30 and 40 MB with just one client ?
| |
| 15:15 | <sepski> was that while booting, or while useing apps ?
| |
| 15:15 | video apps will tax your network severly
| |
| 15:15 | i am talking "productive work"
| |
| 15:15 | not gaming :)
| |
| 15:15 | regular office style
| |
| 15:15 | <steven43126> ahhhhh, i think i testded viewing a small video on youtube !
| |
| 15:15 | cliebow has joined #ltsp | |
| 15:16 | <sepski> steven43126, not suited for ltsp imho
| |
| 15:16 | steven43126, but if you realy have 1ghz clients you can run them as ltsp diskless clients
| |
| 15:18 | <steven43126> i am right in thinking ltsp does just use XDMCP aren't i ?
| |
| 15:18 | <sepski> ltsp5 uses ldm, ssh based
| |
| 15:19 | <pscheie> 4.2 and lower use(d) xdmcp
| |
| 15:19 | <steven43126> ldm does the ssh not add overhead ?
| |
| 15:19 | <sepski> steven43126, it does.
| |
| 15:19 | but adds security.
| |
| 15:20 | since people can't sniff all passwords right out of the network
| |
| 15:21 | and it also creates a channel for things like ltspfs
| |
| 15:21 | <steven43126> sepski, does it use ssh compression ?
| |
| 15:21 | <sepski> not by default i imagine
| |
| 15:22 | <steven43126> sepski, thanks for your time
| |
| 15:22 | i shall have a look at ldm and ltsp
| |
| 15:22 | <sepski> steven43126, edubuntu or debian-edu will give you a preconfigured ltsp server out of the box.
| |
| 15:24 | <pscheie> as will k12ltsp
| |
| 15:24 | rasmuson has joined #ltsp | |
| 15:25 | <pscheie> k12ltsp = fedora-based
| |
| 15:26 | <sepski> pscheie, didnt know k12 had a ltsp5 version out yet
| |
| 15:26 | msinhore has quit IRC | |
| 15:31 | <pscheie> it doesn't
| |
| 15:31 | latest version is ltsp 4.2 based
| |
| 15:31 | <sepski> ah
| |
| 15:31 | <pscheie> current release is version 6 based on fc6
| |
| 15:32 | I think the next release is supposed to include ltsp 5
| |
| 15:32 | <sepski> have anyone done any serious testing on ltsp on a regular dumb switch vs ltsp on a qos switch
| |
| 15:32 | i assume as long as the network is dedicates qos wont do much
| |
| 15:33 | <pscheie> I think several people on the k12ltsp use dumb 24+2 switches
| |
| 15:33 | <sepski> except perhaps lower the impact of booting clients on allready running session

| 22:48 | <tessier__> Hello all!
| |
| 22:48 | I am having a really strange problem with ltsp.
| |
| 22:48 | When a terminal dies (powered off, whatever) the users session never gets killed on the server
| |
| 22:49 | I have straced the gdm-binary and it is indeed pinging every 15 seconds
| |
| 22:49 | Then when it fails a ping the gdm-binary does a kill() on itself
| |
| 22:49 | Problem is, this would seem to leave nobody around to reap the exit status of gnome-session
| |
| 22:49 | So gnome-session goes orphan
| |
| 22:49 | And all of the children processes remain
| |
| 22:49 | And the user is unable to log back into the terminal.
| |
| 22:49 | Anyone else seen this?
| |
| 22:50 | s/orphan/zombie/
| |
| 22:52 | This happens on our FC4 and FC5 based servers.
| |
| 22:53 | PingIntervalSeconds=15 is defined in the gdm.conf on both. It is a default but I wanted to specifically define it anyway to see if it helped.
| |
| 22:53 | I think I'll post to the ltsp mailing list about this one. Thanks.
