| 07:13 | <Hyperbyte> alkisg, right... problem is I've horribly busy the past few months
| |
| 07:14 | I think I'm in my last two weeks of being horribly busy though
| |
| 07:21 | +been
| |
| 07:21 | Travel organisation I work fulltime for is launching it's new travel season with whole new IT system for customers, that's lots of work for me
| |
| 07:22 | Radio Capelle where I volunteer has a completely new IT and studio which requires some attention every now and then still
| |
| 07:22 | Then Radio 1 evening gig has started it's new season again
| |
| 07:22 | And for my own company I also have a new customer I need to keep satisfied....
| |
| 07:22 | So....
| |
| 07:22 | LTSP kind of had to take a back seat. :(

| 08:30 | <jimjimovich> anyone experiencing problems with flash drives using ubuntu 12.04 and ltsp-pnp?
| |
| 08:31 | all flash drive capacities are always reported with strange, incorrect, numbers. things don't copy correctly or report errors when trying to open files. these are thin clients.
| |
| 08:34 | <alkisg> Thin clients? So, ltspfs.. no idea there
| |
| 08:48 | <jimjimovich> alkisg: if I remember right, there was a bug in the main ubuntu ltsp that was fixed a while back.
| |
| 08:48 | <alkisg> There was one related to 64bit clients
| |
| 08:48 | But the fix should be there in 12.04
| |
| 08:49 | And the problem was that it didn't work at all, it wasn't that it malfunctioned
| |
| 08:49 | <jimjimovich> This is a real bummer. Things worked so well in 10.04 ... kind of regretting the upgrade :)
| |
| 08:50 | although, the pnp part is making life a lot easier
| |
| 08:50 | <alkisg> Many schools here decided not to upgrade to 12.04
| |
| 08:50 | ltsp-pnp is good for fat clients, or at least mixed thin/fat labs, not plain thins...
| |
| 08:51 | <jimjimovich> why not for thins?
| |
| 08:51 | we actually have a bit of a mix, but we've mostly abandoned our fat clients because we ran into too many limitations
| |
| 08:51 | <alkisg> It doesn't make much sense to publish the whole server disk with all the applications, i.e. 1Gb+ chroot instead of a 200 mb chroot
| |
| 08:51 | What kind of limitations?
| |
| 08:52 | <jimjimovich> some networking problems, no access to some apps due to permissions
| |
| 08:52 | we also have a lot of computers with low amounts of RAM and slow Atom processors
| |
| 08:53 | <alkisg> atoms with 768 ram should be better as fats than as thins
| |
| 08:54 | <jimjimovich> Yeah, this is what I've heard. Unfortunately, modern browsers will quickly use up GBs of ram and bring everything to a halt
| |
| 08:57 | <alkisg> NBD_SWAP is automatically activated for fats with < 800mb ram, and you can manually activate even for clients with more RAM
| |
| 08:57 | E.g. NBD_SWAP=True for all
| |
| 08:59 | <jimjimovich> is it possible to have a fat client run some apps on the server? (like the reverse of localapps?)
| |
| 08:59 | <alkisg> LTSP_REMOTEAPPS=True and then ltsp-remoteapps app
| |
| 09:00 | <jimjimovich> oh wow, how did I miss that?
| |
| 09:01 | dobber has joined IRC (dobber!~dobber@213.169.45.222) | |

| |
| 09:02 | <jimjimovich> Thanks, I have no idea how I missed that.

| 09:07 | <ltspuser_07> hello
| |
| 09:07 | I'm having a problem
| |
| 09:09 | I have a squeeze filesystem and I am opening sessions using LDM and my firefox and thunderbird and other applications have a different theme
| |
| 09:09 | using xrdp all looks good...
| |
| 09:09 | but I need to use LDM
| |
| 09:10 | I have taken a snapshot with the problem
| |
| 09:10 | http://imagebin.org/230484
| |
| 09:10 | I am using Ubuntu 12.04
| |
| 09:11 | in firefox the menu bar is light grey
| |
| 09:11 | and the theme that I'm using is Ambiance
| |
| 09:11 | so the firefox menu bar should have the same colours of the theme
| |
| 09:11 | right?

| 09:21 | <jimjimovich> alkisg: When I boot as a fat client, I can't launch epoptes
| |
| 09:22 | <alkisg> jimjimovich: I think I write that on the wiki, you need to use remote apps there
| |
| 09:22 | So that it launches on the server, where the clients connect
| |
| 09:22 | <jimjimovich> got ya. i think this remote app thing might solve all the problems we were having
| |
| 09:23 | <alkisg> http://www.epoptes.org/documentation/fat-clients
| |
| 09:24 | <jimjimovich> okay, here's another problem. I stick a flash drive in and it says I can't mount it because I don't have permissions
| |
| 09:25 | <alkisg> What's the output of `id` ?

| 09:28 | <jimjimovich> alkisg: http://pastebin.com/GFT29rDf
| |
| 09:29 | hmmm ... maybe my permissions are messed up
| |
| 09:29 | <alkisg> Try: udisks --mount /dev/sdb1
| |
| 09:29 | (or whatever sdb* the stick is)
| |
| 09:31 | <ltspuser_07> any help for my problem with firefox themes
| |
| 09:31 | yesterday i talk to alkisg but still with no resolution
| |
| 09:32 | <alkisg> jimjimovich: I just tried on a fat client without putting the user in any groups at all, it auto-opened without me doing anything special
| |
| 09:32 | <jimjimovich> we had a problem with all of our permissions (even standard ones created with a new account) getting deleted when we did the upgrade.
| |
| 09:33 | permission is denied with udisks as well
| |
| 09:38 | <ltspuser_07> any help please?
| |
| 09:38 | any idea?
| |
| 09:39 | <alkisg> jimjimovich: first check the user ownerships under /home/username, then try ls -lha /dev, and see if the system groups match, etc etc
| |
| 09:44 | <jimjimovich> alkisg: the ownership for the home folder is "administrator:administrator"
| |
| 09:44 | <ltspuser_07> any help to change the firefox theme
| |
| 09:44 | ?
| |
| 09:44 | <jimjimovich> for /dev, I'm getting mostly root
| |
| 09:44 | <ltspuser_07> I want to have the same theme as ubuntu on firefox
| |
| 09:44 | I'm opening sessions using LDM
| |
| 09:45 | <jimjimovich> ltspuser_07: as far as i know, LDM has nothing to do with firefox themes
| |
| 09:45 | alkisg: /dev/sda1 has permissions root:disk
| |
| 09:46 | <alkisg> jimjimovich: that part is fine
| |
| 09:47 | <ltspuser_07> yes jimjimovich
| |
| 09:47 | but when I use xrdp it works fine
| |
| 09:47 | I don't understand...
| |
| 09:47 | <alkisg> jimjimovich: for /dev, you should be getting groups different than root for most of the stuff there
| |
| 09:49 | <jimjimovich> so does my user need to be part of the disk group?
| |
| 09:49 | litlebuda has joined IRC (litlebuda!~litlebuda@204.0.166.178.rev.vodafone.pt) | |
| 09:49 | <alkisg> No, udisk takes care of that
| |
| 09:50 | jimjimovich: e.g. if /home/administrator/.gvfs doesn't have the correct owner, you'll have multiple permission problems...
| |
| 09:51 | <jimjimovich> it seems to have the right permissions
| |
| 09:52 | litlebuda has left IRC (litlebuda!~litlebuda@204.0.166.178.rev.vodafone.pt, Remote host closed the connection) | |
| 09:54 | <ltspuser_07> anybody?
| |
| 09:54 | I see that my problem is verty dificult to solve...
| |
| 09:54 | <jimjimovich> alkisg: /home/administrator/.gvfs on the server or on the fat client?
| |
| 09:55 | <alkisg> Should be the same, let's say fat...
| |
| 09:55 | <jimjimovich> on the client it's administrtor:administrator, on the server it's a bunch of question marks
| |
| 09:56 | well, for my user it is, for another user (that also doesn't work), they are the same
| |
| 09:57 | <alkisg> Try to create a new user, see if it helps...
| |
| 09:58 | <jimjimovich> that's exactly what i was doing when you typed that :)
| |
| 09:58 | <alkisg> Btw, any permission problems on the server are transferred on the chroot with ltsp-pnp
| |
| 09:58 | <jimjimovich> new user can not mount the disk either
| |
| 10:00 | <alkisg> Sounds like system-wide permission problems then
| |
| 10:00 | That's gnome, right?
| |
| 10:00 | <jimjimovich> yeah, gnome
| |
| 10:01 | <alkisg> Yup I tried it half an hour ago, worked out of the box, so something is wrong in your installation. Can you try the same thing directly on the server?
| |
| 10:01 | <jimjimovich> sure
| |
| 10:04 | automounts with no problems on the server
| |
| 10:05 | also, is it right that I should not be able to do anything as sudo on the fat client?

| |
| 13:09 | mgariepy: that said, I'd kinda like arriving before 6pm for once ;)
| |
| 13:10 | mgariepy: so probably leaving Sherbrooke around 8:30-9am or something like that so we can stop to eat somewhere along the way and still arrive around 4pm over there
| |
| 13:24 | <mgariepy> stgraber, i would like to arrive a 4pm as well ;)

| 14:06 | <ltspuser_70> ok
| |
| 14:06 | i need to change this
| |
| 14:06 | http://imagebin.org/230484
| |
| 14:06 | if you see this printscreen
| |
| 14:06 | you can see that firefox doesn't assume the ubuntu's theme
| |
| 14:06 | I have a squeeze filesystem
| |
| 14:07 | and I'm using LDM and gnome...
| |
| 14:08 | <alkisg> And if you login directly on the server, firefox is fine?
| |
| 14:08 | <highvoltage> I *think* I fixed that before by installing the light-themes package in the chroot
| |
| 14:09 | <alkisg> highvoltage: for server apps? or for localapps? ltspuser_70 says it's not a localapps firefox...
| |
| 14:09 | <highvoltage> ah I see
| |
| 14:10 | <ltspuser_70> for server apps...
| |
| 14:10 | <alkisg> (05:08:06 μμ) alkisg: And if you login directly on the server, firefox is fine?
| |
| 14:10 | <ltspuser_70> yes...
| |
| 14:10 | if i use etch based filesystem and user xrdp it's all good...
| |
| 14:11 | use*
| |
| 14:11 | <alkisg> If you run `ps aux|grep firefox` on the server, do you see the firefox process running?
| |
| 14:11 | If not, then it's a "localapp" firefox
| |
| 14:14 | <ltspuser_70> yes i see
| |
| 14:14 | in this case is user2 that is using firefox...
| |
| 14:15 | i have installed another theme
| |
| 14:15 | and on the server if i change the firefox change
| |
| 14:15 | in LDM session is not changing...
| |
| 14:16 | <alkisg> I can't think of how ltsp would break firefox themes while they'd work with e.g. xrdp...
| |
| 14:17 | <ltspuser_70> it could be the filesystem...
| |
| 14:17 | I said that worked using xrdp but in a debian etch filesystem
| |
| 14:18 | in this LDM session I am usinga a squeeze filesystem

| 14:21 | <ltspuser_70> locally is working

| 14:22 | <ltspuser_70> I can't use xrdp because ubuntu's indicator-applet crash
| |
| 14:23 | sometimes gives an error and the bar with date and start menu disappear
| |
| 14:25 | <||cw> you're using ubuntu's indicator-applet on debian?
| |
| 14:26 | staffencasa has joined IRC (staffencasa!~staffenca@8-220.ptpg.oregonstate.edu) | |
| 14:26 | <alkisg> ltspuser_70: btw why you're using a debian chroot on an ubuntu server? (instead of an ubuntu chroot?)
| |
| 14:27 | <ltspuser_70> because I have thin clients with that filesystem optimized...
| |
| 14:28 | so I have a squeeze filesystem and I'm trying to put all working with Ubuntu 12.04
| |
| 14:28 | <||cw> so they're debian based thin clients, not nfs/nbd?
| |
| 14:29 | is it running firefox as a localapp?
| |
| 14:30 | <ltspuser_70> yes
| |
| 14:30 | they are nfs
| |
| 14:30 | and firefox is running on server
| |
| 14:31 | <||cw> um
| |
| 14:31 | <ltspuser_70> but my DHCP and DNS server is a Debian
| |
| 14:31 | <||cw> no. localapp means it runs on the thin client directly
| |
| 14:31 | and then need firefox-gnome-support on the thin client and the ubuntu theme
| |
| 14:31 | I think
| |
| 14:32 | if it runs on the server, there's not really any reason it shouldn't work
| |
| 14:32 | <ltspuser_70> but firefox runs on ubuntu server...
| |
| 14:32 | <||cw> unless you're missing something. so compare your etch and squeeze packages and see what's different
| |
| 14:34 | <ltspuser_70> I've done that...
| |
| 14:34 | <||cw> run this and dump to a file on each, then diff them dpkg --get-selections | grep '[[:space:]]install$'| awk '{print $1}'
| |
| 14:35 | there will be many differences though
| |
| 14:35 | * alkisg notes that ltspuser_70 didn't say that ldm was working ok with etch, just xrdp | |
| 14:36 | <ltspuser_70> I have a debian server which is DNS, DHCP,NFS server and provides a filesystem to thin clients and then in lts.conf there is a configuration to open a session on Ubuntu 12.04
| |
| 14:38 | <||cw> alkisg: can corect me if I'm wrong, but I think the only way a different thin client image can theme any app differently is if the app is running as a localapp and the client image is missing the themes.
| |
| 14:39 | <ltspuser_70> I have tried open a X session but I think my xorg.conf is not working...
| |
| 14:39 | yes i understand
| |
| 14:39 | <alkisg> That's what I thought too, but appareantly it can be done...! I've also seen all the theme breaking when gnome-settings-daemon dies, but I've never seen the theme breaking only for some apps (while working locally)
| |
| 14:39 | So I can't think of anything here
| |
| 14:39 | <ltspuser_70> but could be some package missing and the theme don't change...
| |
| 14:40 | I don't know...
| |
| 14:40 | can you help me to build my xorg.conf??
| |
| 14:40 | if it works using a xdmcp session that's enough for me...
| |
| 14:41 | <alkisg> Try SCREEN_07=xdmcp then
| |
| 14:41 | <||cw> you do know it is fairly trivial to have your dhcp server tell thin clients to get the image/nfs from the ubuntu ltsp host right?
| |
| 14:42 | <ltspuser_99> I'm trying to make a thin clients serial port available to a rdesktop session. I know that rdesktop handles redirection of the com port
| |
| 14:42 | the question is, how do I configure the clients com port first?
| |
| 14:43 | I've googled and can't find anything obvious
| |
| 14:44 | <ltspuser_70> alkisg: are you telling me to put in lts.conf SCREEN_07=xdmcp? And then?
| |
| 14:44 | <alkisg> ltspuser_70: that will make your client use XDMCP
| |
| 14:44 | So you'll see if it works with xdmcp or not
| |
| 14:44 | You'll need to enable xdmcp on the ubuntu server too, of course
| |
| 14:44 | <ltspuser_70> ||cw: yes I know... and it's working like that
| |
| 14:45 | <||cw> so why a debian image?
| |
| 14:45 | <ltspuser_70> yes
| |
| 14:45 | it's enable
| |
| 14:45 | because the debian is the DHCP and DNS and LTSP server...
| |
| 14:45 | and the terminal opens session on Ubuntu
| |
| 14:45 | <alkisg> ltspuser_70: then that's all you need to change, your lts.conf, nothing more, to have your client use xdmcp
| |
| 14:47 | Phantomas has left IRC (Phantomas!~Phantomas@ubuntu/member/phantomas, Ping timeout: 244 seconds) | |
| 14:48 | <ltspuser_70> yes...
| |
| 14:49 | but if I only configure that it's opening xdmcp session to the debian server (the DHCP,DNS server)
| |
| 14:49 | I want to open to Ubuntu
| |
| 14:51 | <alkisg> You do that with SERVER=ubuntu-ip currently, or with NBD_SERVER or NFS_SERVER, right?
| |
| 14:51 | Or do you use LDM_SERVER?
| |
| 14:51 | Anyway, put SCREEN_02=shell, and try X -query ubuntu-ip
| |
| 14:51 | <ltspuser_70> I have like this
| |
| 14:51 | SERVER = "192.168.69.199" DNS_SERVER = "192.168.69.199" SEARCH_DOMAIN = "teste.com" #LDM_SERVER = "192.168.69.212" SCREEN_01 = "none" SCREEN_02 = "xdmcp"
| |
| 14:52 | and the other options...
| |
| 14:52 | <alkisg> Try with only SCREEN_02=shell, and X -query ubuntu-ip, to see if it works fine
| |
| 14:53 | <ltspuser_70> ok
| |
| 14:54 | I think it wont work because of mine xorg.conf

| |
| 14:57 | no...
| |
| 14:57 | with X -query ubuntu-ip
| |
| 14:57 | <alkisg> Then you have a server misconfiguration wrt XDMCP

| |
| 14:58 | <ltspuser_70> i think it's my xorg.conf...

| |
| 15:00 | If your xorg had problems, you wouldn't see a mouse
| |

| 19:28 | <mikec> i feel there must be a standard way of implementing pam/krb5 logins for ltsp. I am able to get tickets by using kinit <username>@REALM on the server, but how can I get it so that users at the ldm screen (or some other login display) can authenticate against the kerberos realm?
| |
| 19:28 | I ran pam-auth-update and everything is enabled there
| |
| 19:30 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 19:32 | <vagrantc> mikec: the same way you would authenticate ssh ...
| |
| 19:36 | <mikec> so if i have pam enabled and krb5.conf is set, i should be able to authenticate to my kerberos realm from the ldm login screen without further config?
| |
| 19:37 | <vagrantc> as long as that's how it works for ssh
| |
| 19:37 | i don't really know kerberos ... do you typically need configuration on both sides?

| |
| 19:39 | <dead_inside> congrats
| |
| 19:39 | <mikec> i guess i dont really know what the ldm login screen is doing. is it going "ssh <username>@<ltsp-server>"? where as kerberos it would need to "kinit <username>@<ltsp-server>"
| |
| 19:40 | <ltspuser_23> what i would like to know is, is it possible to use the tv card in the thin client
| |
| 19:40 | the thin client is a stripped down old pc
| |
| 19:41 | <mikec> i guess if ssh is supposed to authenticate to the kerb realm natively via ldm, its not working cause I can't seem to log in using existing users that are on that KDC

| 19:42 | but I'm at a loss of what futher config would even need to happen
| |
| 19:42 | if any from the ltsp side
| |
| 19:42 | i would imagine I'm not the first person to need this

| 19:52 | <muppis> ltspuser_23, yes it is. You just need to know what that tv card needs to work and install all those to chroot.
| |
| 19:52 | <alkisg> cliebow: nah, no sposorship this year unfortunately :(

| 19:55 | <ltspuser_23> when you say chroot that means to my i386 image i have created
| |
| 19:55 | ?
| |
| 19:56 | <muppis> No, /opt/ltsp/i386 directory. Image is created from there.
| |
| 19:57 | <ltspuser_23> ok thank you
| |
| 20:04 | muppis, would you suggest i try boot the thin client via something like a live cd and get the card up and running there and then move the required modules and other files to the chroot?
| |
| 20:06 | <muppis> ltspuser_23, enable rootshell to client and test there, then it's easier to do it in chroot.

| |
| 20:06 | <muppis> Meh.
| |
| 20:07 | <alkisg> vagrantc: could you check https://bugs.launchpad.net/epoptes/+bug/1054665 ? We only need a dh_installinit override there, right?
| |
| 20:07 | And specify e.g. that epoptes should start in 30, instead of the default 20...
| |
| 20:11 | Does this seem ok? override_dh_installinit: dh_installinit $@ -u defaults 30
| |
| 20:11 | <vagrantc> alkisg: the numbers are practically meaningless nowadays if you use the LSB headers
| |
| 20:11 | <alkisg> vagrantc: ubuntu doesn't
| |
| 20:11 | insserv does, but afaik ubuntu doesn't use insserv
| |
| 20:11 | <vagrantc> oh right.
| |
| 20:19 | <alkisg> Pushed
| |
| 20:21 | <vagrantc> mikec: ldm doesn't run the "kinit <username>@<server>" but you might be able to through ldm hooks, if that's needed.
| |
| 20:25 | <kb8wmc> alkisg: Thank you so much for your help, I managed to get my configuration settings correct enough to be able to actually boot to xserver now, I now need to configure the client to view applications from the server
| |
| 20:28 | <alkisg> kb8wmc: out of curiosity, how?
| |
| 20:28 | To view applications from the server, you just need to login with a server user
| |
| 20:33 | <kb8wmc> alkisg: it was all in my configuration set ups....I changed to vesa, deleted nomodeset, changed parameters in my stansa for the T40, set resolution at 800x600

| 20:43 | <Davew_> Hi, I had a conversation here last night about Thin Client Manager and Epoptes. I checked up what Epoptes can do
| |
| 20:44 | and although it offers some interesting monitoring capability involving groups it appears to have no user creation capability
| |
| 20:45 | <alkisg> Indeed, did thin client manager have user creation capabilities?
| |
| 20:45 | <Davew_> I have to get some 30 plus students into a group called students using their ID's as usernames.
| |
| 20:47 | Since Thin client Manager has been the subject of Bug #1010089 presumably unless someone knows the fix then using this package is counted out.
| |
| 20:48 | <alkisg> ogra_: did thin client manager have user creation capabilities?
| |
| 20:48 | <Davew_> Does this mean I have to use adduser and also is the group creation which this will give me also compatible with Menu Editor since I will need to create
| |
| 20:48 | a menu
| |
| 20:48 | <ogra_> no, it was plainly for managing the machines
| |
| 20:48 | <alkisg> Davew_: ^
| |
| 20:49 | <ogra_> for session mgmt there was student-control-panel ... but thats even longer dead
| |
| 20:49 | (and had no user creation stuff either)
| |
| 20:49 | <alkisg> We developed sch-scripts for user creation, as we couldn't find any good tools for mass student accounts creation either
| |
| 20:50 | It's currently greek-only, we'll internationalize that next year, like we did with epoptes
| |
| 20:50 | <Davew_> I nthink I am correct in saying that using Thin Client Manager you could create users and add them as members of a group
| |
| 20:50 | <alkisg> For now you can either try the command line or some web-based tool
| |
| 20:50 | Davew_: ogra_ was the thin client manager developer
| |
| 20:50 | So I'm inclined to believe him :)
| |
| 20:51 | <ogra_> well, i wouldnt trust myself here ... its like 4 years ago that i have seen the code last
| |
| 20:51 | or 3
| |
| 20:51 | <Davew_> Stand by will be back in 3
| |
| 20:55 | <alkisg> ogra_: about https://bugs.launchpad.net/tcm/+bug/1010089, there's no "won't fix" option for me, do you get one or it's generally not available and we should use "invalid" instead?
| |
| 20:56 | (or stgraber ^)
| |
| 20:57 | <kb8wmc> alkisg: I uncommented SCREEN_07=ldm and commented out SCREEN_05=startx...client then halts at the invalid card number
| |
| 20:57 | <ogra_> wontfix is right under invalid for me
| |
| 20:57 | primeministerp has joined IRC (primeministerp!~ppouliot@static-71-174-244-26.bstnma.fios.verizon.net) | |
| 20:57 | <alkisg> ogra_: maybe because you're a tcm dev... so maybe you should close that one
| |
| 20:57 | <ogra_> oh, i cant click it
| |
| 20:57 | <alkisg> Heh
| |
| 20:57 | <stgraber> alkisg: it's an upstream bug, not Ubuntu, so only the upstream team can do that
| |
| 20:57 | marked invalid instead :)
| |
| 20:58 | <alkisg> Quick & fine :)
| |
| 20:58 | <stgraber> and I commented
| |
| 20:58 | <ogra_> heh, pete savag (who took over upstream from me) vanished
| |
| 20:58 | so upstream wont care i guess
| |
| 21:00 | its sadly not team owned, so we cant even modify the overview page wheer it says:
| |
| 21:00 | "Thin Client Manager is shipped with Edubuntu and is primarily aimed at making it easy to work administrate a thin client environment"
| |
| 21:00 | <Davew_> Hi again, I will take back the creation of users but you were certainly able to assign users to groups
| |
| 21:01 | brunolambert has left IRC (brunolambert!blambert@nat/revolutionlinux/x-drruiluieanfnwzc, Ping timeout: 245 seconds) | |
| 21:01 | <ogra_> i wonder if we could ask #launchpad for removal
| |
| 21:02 | <alkisg> Davew_: anyway it doesn't make any difference since tcm hasn't been maintained for years and it's not working and it will be removed from ubuntu in future versions etc
| |
| 21:02 | <Davew_> As I am under some pressure now to set up my 12.04 LTSP server for some classes
| |
| 21:02 | <ogra_> its already gone from 12.10
| |
| 21:02 | <Davew_> can I confirm the following :
| |
| 21:02 | <ogra_> or at least on its way out the door
| |
| 21:02 | sadly we cant remove it from 12.04
| |
| 21:02 | i so wish we could
| |
| 21:03 | <Davew_> Firstly I need to use adduser to add clients ?
| |
| 21:03 | <alkisg> We can ship an update that just brings up a dialog saying "please uninstall it, it's not working :P"
| |
| 21:04 | <Davew_> Will standby and wait for a pause gentlemen
| |
| 21:04 | <alkisg> Davew_: either adduser, newusers, the embedded users gnome UI, or some web-based too
| |
| 21:04 | l
| |
| 21:04 | <ogra_> someone would still have to write that code ... even though a zenity script would do :)
| |
| 21:04 | but yu add users, not clients :)
| |
| 21:09 | <alkisg> stgraber: should I close all the bugs in https://bugs.launchpad.net/tcm and https://bugs.launchpad.net/ubuntu/+source/thin-client-manager too?
| |
| 21:09 | <Davew_> How do you suggest I put the clients into groups ?
| |
| 21:10 | <alkisg> Davew_: are we talking about ltsp clients or about users?
| |
| 21:10 | clients == pcs
| |
| 21:10 | <Davew_> The suggestion last night was to use Epoptes
| |
| 21:11 | <alkisg> Epoptes is an ltsp client management tool, it manages computers, not users
| |
| 21:11 | brunolambert has joined IRC (brunolambert!blambert@nat/revolutionlinux/x-qbqyvzdpnzjkzmjv) | |
| 21:11 | <alkisg> tcm was also an ltsp client management tool
| |
| 21:11 | But your question above was about creating users
| |
| 21:12 | User creation is not ltsp related at all, you could be asking in #ubuntu instead if you wanted
| |
| 21:12 | <Davew_> So we have users using a Thin Client Machine
| |
| 21:12 | <alkisg> You just run some tool on the server and create the users
| |
| 21:13 | Either adduser, newusers, the gnome UI for user creation, or some of the web-based tools that exist for that
| |
| 21:13 | TiZ has joined IRC (TiZ!~TiZ@192.122.237.253) | |
| 21:13 | <alkisg> Then the users can login from any ltsp client they want, you do not assign specific users to specific computers
| |
| 21:13 | <TiZ> Hi. How do I make a fat client inherit cups settings from the host?
| |
| 21:14 | <alkisg> TiZ: for example? what settings?
| |
| 21:14 | E.g. you don't want it to think that it has a usb printer connected, when that is connected to the server...
| |
| 21:14 | <TiZ> There's a network printer over samba that I want all the terminals to print to.
| |
| 21:14 | brunolambert has left IRC (brunolambert!blambert@nat/revolutionlinux/x-qbqyvzdpnzjkzmjv, Client Quit) | |
| 21:15 | brunolambert has joined IRC (brunolambert!blambert@nat/revolutionlinux/x-facxqahdtwmiknik) | |
| 21:15 | <Davew_> Thin Client Manager had a split screen with a user list on the LHS and the process view on the right. I apologise for confusing clients and users
| |
| 21:15 | <alkisg> TiZ: you can enable network printer discovery on the chroot, and share it from the server
| |
| 21:18 | <TiZ> alkisg: That won't work... It's a specific printer that I need to use, and it needs to be authenticated into.
| |
| 21:19 | <alkisg> Where are the authentication credentials stored? Are they per-user?
| |
| 21:19 | Or they're stored e.g. in /etc/cups/printers.conf?
| |
| 21:20 | <stgraber> alkisg: yeah, I think we should close at least all of the Ubuntu bugs, quite possibly the upstream ones too as it's very unlikely that Pete will ever work on it again
| |
| 21:20 | <TiZ> well, there's a specific NT user made for the terminals that we use to connect to the printer, so we include the domain, username, and password in the url we use to connect to the printer.
| |
| 21:20 | <alkisg> stgraber: ok, will do so tomorrow morning, if noone beats me to it
| |
| 21:21 | <TiZ> We can't share it over the network because that will potentially allow students here (I work for a law college) to bypass authentication.
| |
| 21:22 | <alkisg> OK. Doesn't the default CUPS_SERVER="the ltsp server" point the fat clients to see whatever printers the server sees? If not, I guess copying printers.conf to the chroot will do it...
| |
| 21:22 | <TiZ> When our terminals were running in thin client mode, it just worked. We switched them over to fat client mode so that any activity that consumed a lot of resources wouldn't affect all of the terminals.
| |
| 21:23 | I thought copying the configuration to the chroot would do it too, but that didn't work...
| |
| 21:23 | <alkisg> Try also CUPS_SERVER=localhost in lts.conf
| |
| 21:23 | Otherwise the fat clients try to use the ltsp server as their cups server
| |
| 21:24 | <TiZ> Localhost OR the ltsp server would be fine, because the ltsp server has the printer we want added into it.
| |
| 21:24 | But when I try to print from one of the terminals, the only printer that appears is print to file.
| |
| 21:24 | <alkisg> (localhost == the fats themselves)
| |
| 21:24 | <TiZ> I figured, but the same cups configuration from the server was copied into the chroot.
| |
| 21:25 | I just copied all of /etc/cups to be safe.
| |
| 21:25 | Or was that bad?
| |
| 21:25 | <alkisg> Yes, but it's possible that the fat clients have no access to the server cups if you don't check [x] publish this printer to the network
| |
| 21:25 | <TiZ> Okay... I can give that a try.
| |
| 21:25 | <alkisg> So try with CUPS_SERVER=localhost first and see what that gives you
| |
| 21:26 | <TiZ> I'll try that.
