| kidar | hi, i need help setting up a classroom with edubuntu | 09:27 |
|---|---|---|
| alkisg | kidar: hi, ask your questions, and if someone knows the answer, he will probably answer. | 09:28 |
| kidar | i have managed to setup a server using ltsp. created a user and managed to logon using thin client. now i need to setup the server so that the teacher can monitor the thin clients | 09:33 |
| alkisg | sudo apt-get install italc-master | 09:34 |
| alkisg | That should do it... italc.sourceforge.net is the program web page, if you want to read more | 09:34 |
| kidar | will it work with edubuntu 10.04? | 09:35 |
| alkisg | Yes | 09:35 |
| alkisg | (unless you hit any bugs, e.g. on a specific lab it used to crash on me every few seconds - on other labs it worked fine for years) | 09:35 |
| kidar | do i need to install anything for the thin clients? this is a first for me so pls dont be annoyed with the questions | 09:35 |
| alkisg | No. Just install italc-master and ensure that the teacher is in the admin group, | 09:36 |
| alkisg | then logoff / logon the teacher, and then logon the user | 09:36 |
| alkisg | It should automatically be able to monitor the user, and even take control of his screen | 09:36 |
| kidar | in the new version of edubuntu under add programs there is a program called controlaula | 09:37 |
| kidar | when u say teacher u mean i need to create another user as a teacher and use that user to logon to the server? | 09:38 |
| * alkisg doesn't like controlaula at all, it's very non-professional | 09:38 | |
| alkisg | About the teacher, yes, something like that | 09:39 |
| alkisg | The teacher accound needs to be a member of the admin group | 09:39 |
| alkisg | The default account you created as part of the installation can be used as well | 09:39 |
| alkisg | (it's already in the admin group) | 09:39 |
| alkisg | Just remember to logoff/logon after installing italc | 09:40 |
| kidar | ok, will try that. now for creating users (the children accounts) how would i do that, meaning i want to give them access for now only to the education stuff and office? | 09:41 |
| kidar | one question how would i be abl to setup thin clients and normal pc to logon to the same server | 09:43 |
| alkisg | What do you mean "normal pcs to logon to a server"? | 09:43 |
| alkisg | Have you done that somehow? | 09:43 |
| alkisg | (e.g. with LDAP?) | 09:43 |
| kidar | see i have the edubuntu server setup with ltsp | 09:44 |
| alkisg | To create users, just use the gnome users-admin program | 09:44 |
| kidar | now i want other pcs in the class room which are not thin clients to be monitored by the same server | 09:45 |
| alkisg | You can install italc on them too | 09:45 |
| kidar | regarding users how can u prevent them from deleting programs of the server? | 09:45 |
| alkisg | They can't, they don't have the rights | 09:46 |
| alkisg | If you create a normal user from the gnome users-admin dialog (and not an administrator), then that user cannot delete programs | 09:46 |
| kidar | ok | 09:47 |
| kidar | would the dhcp running for ltsp give out an IP to a normal pc on the same network? | 09:47 |
| alkisg | Yes | 09:48 |
| alkisg | Unless you use 2 NICs on the edubuntu server | 09:48 |
| alkisg | One for the thin clients and another for your existing network | 09:49 |
| alkisg | But you can also use your existing dhcp server and remove the one from edubuntu | 09:49 |
| kidar | i do, one is setup for the the ltsp and the other is on my internet network | 09:49 |
| alkisg | Then your dhcp server will only be used for the card with IP=192.168.0.1 (or the one you specify) | 09:50 |
| kidar | is there a way of also managing the thin clients ? | 09:52 |
| alkisg | What do you mean "managing"? | 09:53 |
| kidar | i mean for the classroom should i be doing anything else? | 09:53 |
| alkisg | I can't think of anything | 09:56 |
| kidar | ok 1 more question, firstly thank u very much for italc u are great | 09:57 |
| kidar | no i need to know whether italc works on both nics or only one | 09:58 |
| kidar | because i just ran it on the server and now it picks up my laptop which is on the internet nic | 09:59 |
| alkisg | It runs on both | 09:59 |
| alkisg | So you can manage both thin clients and normal pcs | 09:59 |
| kidar | will it pick up the thin clients(ltsp) on the other | 09:59 |
| alkisg | (and even windows pcs) | 09:59 |
| kidar | great u r a star. do u know by the way if there is a version out in zulu. on sunday i went to a rural community center where they have some old pcs and 1 new one thought i could load edubuntu there | 10:00 |
| alkisg | I've no idea about zulu | 10:02 |
| kidar | just by the way, i am based in durban south africa, going to do 3 schools here, so if i can be of some help, i would not mind | 10:03 |
| alkisg | Nice - I think highvoltage is from africa as well - I'm from Greece myself. | 10:06 |
| alkisg | You may want to check about the new fat client support in 10.04 too | 10:06 |
| alkisg | (instead of maintaining normal PCs, you boot those from the ltsp server too but as fat clients, not thin) | 10:07 |
| kidar | meaning, i am still new | 10:07 |
| kidar | where do i find help on the fat clients? booting from them will use less resource from the ltsp server correct? | 10:08 |
| alkisg | It would use the local client CPU + RAM | 10:09 |
| alkisg | What are your client specs? | 10:09 |
| alkisg | How much RAM do they have, and what CPUs? | 10:09 |
| kidar | the clients are acer, p4 3.0ghz, 512 | 10:11 |
| kidar | they all have hard drives | 10:11 |
| alkisg | Yeah they'd work better as fat clients than as thin | 10:12 |
| alkisg | https://help.ubuntu.com/community/UbuntuLTSP/FatClients | 10:12 |
| alkisg | And if they have a local swap partition, also put USE_LOCAL_SWAP=True in lts.conf | 10:13 |
| kidar | do i need to install ubuntu on the fat clients? | 10:16 |
| kidar | the current config of the clients is windows xp at the moment, i just took away the server, which has pf 3.0ghz 1gig ram and 250gig sata hd | 10:18 |
| kidar | the class room has 24 pcs, so going to purchase additonal 3gig to make 4 | 10:19 |
| alkisg | No, you don't need to install ubuntu on the fat clients | 10:19 |
| alkisg | Your setup is similar to what we use here in greece | 10:19 |
| alkisg | Do your clients support "boot from network"? | 10:20 |
| alkisg | (if they have onboard cards, usually yes, but if they have pci cards, usually not) | 10:20 |
| kidar | i guess so :) as they are p4's with on board nics | 10:20 |
| kidar | i have another school that has pci cards and they are using win98 curently | 10:21 |
| alkisg | I guess those would work best as thin clients | 10:22 |
| kidar | the pci cards are realtek, but need to check the bios i guess as these are old pcs p4 1.6ghz | 10:22 |
| alkisg | I put grub4dos on our windows 98 labs, and load gpxe so that they can boot from network without using a floppy / cd etc | 10:22 |
| alkisg | For windows 2000/XP/Vista labs we even developed a tool based on the debian installer, which again puts a "boot from network" option in the windows bootloader | 10:23 |
| kidar | talk to me maybe i should do what u did, did u remove ur windows xp? | 10:24 |
| alkisg | No we don't touch them at all, except for the boot loader | 10:24 |
| alkisg | So any teacher that needs to work on XP can do so. So most of our labs are dual boot, windows + ltsp | 10:25 |
| kidar | i will be very glad to do the same here | 10:25 |
| alkisg | We even developed an italc replacement that lets us manage thin + fat client labs, but currently it's in greek only - we will internationalize it after 2 years. http://wiki.ubuntu-gr.org/sch-scripts/screenshots | 10:26 |
| alkisg | Here's the boot manager for 2000/XP/Vista (it's not working on windows 98 nor on windows 7): http://users.sch.gr/alkisg/tosteki/index.php?action=dlattach;topic=2136.0;attach=1617 | 10:26 |
| alkisg | For the windows 98 labs, the easiest way is to use a floppy from: http://rom-o-matic.net/gpxe/gpxe-1.0.0/contrib/rom-o-matic/build.php | 10:27 |
| kidar | downloade first one. | 10:29 |
| kidar | so with the win 98 i need to boot using the floppy? | 10:29 |
| alkisg | There's another way, with grub4dos | 10:30 |
| kidar | go for it, i am open to all the suggestions | 10:30 |
| alkisg | Here's a google translation of a how-to I wrote a while back: http://translate.google.com/translate?js=y&prev=_t&hl=en&ie=UTF-8&layout=1&eotf=1&u=http%3A%2F%2Fusers.sch.gr%2Falkisg%2Ftosteki%2Findex.php%3Ftopic%3D1451.0&sl=auto&tl=en | 10:31 |
| alkisg | (you only need that how-to for windows 98, not for xp) | 10:32 |
| kidar | very nicely done. | 10:33 |
| kidar | may i ask what do u do in greece | 10:34 |
| alkisg | I'm a teacher, but I'm also in charge of deploying LTSP in greek schools | 10:35 |
| alkisg | So I joined the LTSP development team a while back, helped in fat clients implementation, wrote 2-3 ltsp installation manuals in greek, developed sch-scripts etc | 10:36 |
| kidar | nice, u teach IT/ Linux i guess | 10:36 |
| alkisg | I'm teaching in secondary schools, so nothing fancy - some openoffice, some web, a little programming in logo... | 10:37 |
| alkisg | (IT teacher, yeah) | 10:37 |
| kidar | i have my own IT company, worked for UNHCR in the IT section for 12yrs ,now on my own like ubuntu and want to roll it out to s many people schools, etc as i can | 10:38 |
| kidar | tell me can u send the file grubpxe.zip here. i am having a problem downloading from ur page | 10:39 |
| alkisg | Heh I forgot I also wrote that how-to in english: https://help.ubuntu.com/community/UbuntuLTSP/grubgpxe | 10:39 |
| alkisg | Just click on that link: http://users.sch.gr/alkisg/tosteki/index.php?action=dlattach;topic=1451.0;attach=830 | 10:40 |
| kidar | done. so are u always here?, as u have solved 99% of my problems :) | 10:41 |
| alkisg | :) | 10:42 |
| alkisg | I usually am, but I hope to be away for the next 2 years to finish a phd that I've started | 10:42 |
| alkisg | I like it here too much though so I don't know if I'll be able to stay away for long :P | 10:42 |
| kidar | goning to ask u a really silly question, in edubuntu they say they have stuff from primary to tertiary, where do u find this info. i have loaded it but what do i use? | 10:43 |
| kidar | u are an asset here | 10:44 |
| alkisg | Educational programs usually are in the Applications > Education menu | 10:44 |
| kidar | yeh i know but nothin to point ot secondary or primary. anyway now i am going to test all that u helped me with. | 10:47 |
| alkisg | There's "edubuntu menus" to separate different groups | 10:48 |
| alkisg | OK, give all this a go and if you have any problems you can always come back :) | 10:48 |
| kidar | i actuall have it installed on my laptop as the only os | 10:49 |
| kidar | thx once again will be back to let u know how it went | 10:49 |
| test_ | hi it is kidar again | 11:05 |
| test_ | when i booted my laptop using thin client, the italc did not pick the laptop | 11:06 |
| test_ | hi alkisg it is kidar we chatted just now | 11:07 |
| alkisg | Hi | 11:07 |
| alkisg | So you installed italc-master on the ltsp server, logged off, then logged back on with a user that is in the admin group, and then booted your laptop as a thin client, and it doesn't see it? | 11:08 |
| test_ | yeh | 11:08 |
| alkisg | Did you login on the thin client? | 11:09 |
| alkisg | A user needs to logon before italc sees it... | 11:09 |
| test_ | the server saw the laptop when it was on the internet nic eth1 now i am connected to eth0 | 11:09 |
| test_ | yep, i am chatting to u from the thin client :) | 11:09 |
| test_ | server is right next to me | 11:09 |
| alkisg | italc is a little difficult to troubleshoot when it's not working out of the box, so to make it a little faster as I don't have too much time, can I help you with vnc instead? | 11:10 |
| test_ | ok | 11:11 |
| alkisg | sudo apt-get install x11vnc | 11:11 |
| alkisg | x11vnc -connect alkisg.dyndns.org | 11:11 |
| test_ | on server? | 11:12 |
| alkisg | Whatever :) | 11:12 |
| alkisg | (all apps are running on the server anyway so it doesn't make much difference) | 11:12 |
| test_ | downloaded x11vnc, how do u connect to u? | 11:16 |
| alkisg | (01:11:21 μμ) alkisg: x11vnc -connect alkisg.dyndns.org | 11:16 |
| test_ | i get a screen saying select x11vnc port | 11:17 |
| alkisg | Run the above command from a terminal | 11:18 |
| alkisg | Applications > Accessories > gnome terminal, and type the following command: | 11:18 |
| alkisg | x11vnc -connect alkisg.dyndns.org | 11:18 |
| test_ | done | 11:19 |
| test_ | r u in? | 11:20 |
| alkisg | yup | 11:20 |
| alkisg | test_: x11vnc has some keyboard problems, can you press "|" there? | 11:23 |
| test_ | do u want me to start italc | 11:27 |
| test_ | ok u did someting:) so what was wrong? | 11:28 |
| alkisg | Nope, I didn't do anything | 11:28 |
| alkisg | I was just checking and everything looked ok so I just ran italc | 11:29 |
| test_ | then :) some ghost | 11:29 |
| test_ | i ran italc from the applications system tools | 11:29 |
| alkisg | I don't know, I didn't do anything, I just ran the same thing from the command line. | 11:30 |
| alkisg | OK, back to my phd... :) | 11:31 |
| test_ | yeh, will restart and hopefully all will work. | 11:31 |
| test_ | will let u know | 11:31 |
| kidar | hi alkisg, its working now. no idea why it did not initially. thx for all the help Kidar. | 12:11 |
| alkisg | Good to know :) | 12:12 |
| kidar | going to take a break now :) | 12:12 |
