| mhall119 | morning | 14:56 |
| LedHed | If I want to install a package on LTSP clients, do I install the software in the chroot then update the image, or do I just install it directly on the server? | 16:47 |
| alkisg | the server usually, except for any "localapps" | 16:51 |
| alkisg | !localapps | 16:51 |
| LedHed | ok, and do I have to update the image each time I install new software? | 16:54 |
| LedHed | sorry, I'm a total n00b with LTSP | 16:54 |
| alkisg | No, whenever you install software on the server you don't have to update the image | 17:15 |
| alkisg | Only if you install something on the chroot | 17:15 |
| AlanBell | hi all | 17:24 |
| AlanBell | I am using the edubuntu DVD and trying to get the live LTSP thing going, is there a wiki page or something on the requirements? not sure if I need a separate DHCP server or not | 17:24 |
| alkisg | AlanBell: I don't think that you need a separate dhcp server | 17:31 |
| alkisg | It configures dnsmasq in the nic you tell it to, to function as a dhcp server in 192.168.0.x | 17:32 |
| AlanBell | ah, got it | 17:34 |
| AlanBell | the crossover cable I was using actually wasn't a crossover | 17:34 |
| AlanBell | is there a wiki page or something about the live LTSP and networking? | 17:38 |
| alkisg | I don't think so, what problem are you facing? | 17:39 |
| AlanBell | I don't have any problem at the moment | 17:39 |
| AlanBell | I was going to update it/write it | 17:39 |
| alkisg | highvoltage: ^^^ ? | 17:39 |
| AlanBell | I am trying a few different things like running the DVD in a VM | 17:39 |
| AlanBell | at the moment I have the DVD on hardware and I am booting VMs off it | 17:40 |
| AlanBell | but it would have been good to have a description of what exactly the start LTSP live thing does | 17:41 |
| alkisg | I think it could use a faster user account creation mechanism, and more choices about the network (e.g. function as a proxydhcp server with an external dhcp server around), but other than that it seems fine | 17:41 |
| alkisg | gedit /usr/sbin/ltsp-livecd ;) | 17:41 |
| AlanBell | alkisg: actually yes! that does explain it all :-) | 17:42 |
| alkisg | A wiki page would be nice to have though, for people that don't have code-reading skills | 17:43 |
| AlanBell | yup, tell me where to put it and I will make a start on one | 17:44 |
| alkisg | Hmmm highvoltage should be the one to ask about that, I think | 17:45 |
| AlanBell | things like setting up bridged networking in virtualbox guests would be good to put somewhere | 17:54 |
| AlanBell | any idea how many guests you can get on an Atom based server before it explodes? | 17:55 |
| alkisg | RAM-wise, you need about 512 + 192*guests | 17:58 |
| alkisg | (for a full experience, not just an xterm) | 17:58 |
| alkisg | CPU-wise, it very much depends on if you have LDM_DIRECTX=True (which is true on the livecd), | 17:59 |
| alkisg | and on the apps you use - e.g. flash really hogs the cpu | 17:59 |
| LedHed | whats the benefit of "localapps" ? | 18:43 |
| alkisg | Powerful clients run the apps with their own CPU, relieving the server and the network | 18:46 |
| vmlintu | joerg: hi.. do you have any installation instructions for the portal? | 20:13 |
| joerg | vmlintu, not yet :) sorry | 20:14 |
| joerg | vmlintu, you can try it on our demo server first if you like ;) | 20:14 |
| vmlintu | joerg: how do I do that? | 20:15 |
| vmlintu | joerg: we have now also the user management tool here: http://github.com/opinsys/puavo-users | 20:15 |
| joerg | vmlintu, that looks good. gonna check it out later.... | 20:17 |
| joerg | vmlintu, could be interesting for us as well - the django framework has it's own user management, but some schools will definitely need to use ldap - for printing and proxy auth at least | 20:17 |
| vmlintu | joerg: it works with and without kerberos now and you can administer as many schools as you want in separate ldap databases in single installation | 20:19 |
| joerg | vmlintu, well, that's nice but we won't need it :) | 20:21 |
| joerg | vmlintu, because the schools manage their users themselves... | 20:21 |
| joerg | we have got enough other stuff to do :) | 20:21 |
| joerg | but it is useful for support and backup... | 20:21 |
| vmlintu | joerg: we don't manage the users either, but provide the tools that are centrally managed | 20:21 |
| joerg | we don't have the bandwidth to manage anything centrally | 20:22 |
| vmlintu | joerg: where does the "My files" part store the files? | 20:22 |
| joerg | dsl is unreliable, the upload is quite slow and some schools in the villages only have ISDN dialup | 20:22 |
| joerg | vmlintu, django has the concept of a "storage" | 20:23 |
| joerg | in the demo installation it is simply a folder in the filesystem | 20:23 |
| joerg | but it could be a BLOB field in the DB as well | 20:23 |
| joerg | or you could use the Amazon S3 storage plugin | 20:24 |
| vmlintu | so the files are only accessible through the web interface? | 20:24 |
| joerg | vmlintu, and webdav | 20:24 |
| vmlintu | is webdav working? | 20:24 |
| joerg | sure | 20:24 |
| joerg | at least I hope so :) | 20:24 |
| joerg | vmlintu, http://demo.myserv-project.org/fs/dav | 20:25 |
| vmlintu | ValueError at /fs/dav/ | 20:25 |
| joerg | vmlintu, don't open it in the browser, as it returns an ugly traceback | 20:25 |
| vmlintu | ok | 20:25 |
| joerg | vmlintu, yeah, because you are doing a GET on a webdav collection. | 20:25 |
| joerg | vmlintu, should return a 403 Forbidden or so... | 20:26 |
| joerg | didn't catch that exception yet. | 20:26 |
| joerg | vmlintu, in nautilus you can simply go to: dav://demo.myserv-project.org/fs/dav | 20:26 |
| vmlintu | seems to work | 20:28 |
| vmlintu | do you know if it could use cifs as backend? | 20:29 |
| joerg | vmlintu, hmm, depends what you mean with "backend" | 20:32 |
| joerg | you can store it on an auto mounted cifs storage, sure... | 20:33 |
| joerg | vmlintu, in case that you want your users to access their "My Files" via cifs, it could be a bit tricky... | 20:34 |
| vmlintu | we have used before a web interface that reads everything through cifs with user permissions | 20:35 |
| vmlintu | http://www.simple-groupware.de/cms/WebDisk/IntegraTUMWebDisk | 20:35 |
| joerg | vmlintu, the problem is the permissions: in myserv you can add shares to your profile or to the profile of the group that you just founded. | 20:35 |
| vmlintu | alternative would be to figure out how windows users get the files working without cifs | 20:35 |
| joerg | vmlintu, hmm? just mount it! | 20:36 |
| joerg | vmlintu, I have tried it under Windows XP - just add one of these so called "web folders" | 20:36 |
| joerg | which is just a webdav client | 20:37 |
| vmlintu | hmm.. I guess I have to try that once I find a windows box.. | 20:38 |
| joerg | hehe....that's sometimes difficult, I know. | 20:40 |
| joerg | but there was an issue I think | 20:40 |
| joerg | with webdav stuff not sitting at the webservers root | 20:41 |
| joerg | that caused problems on windoze | 20:41 |
| joerg | that's why I should add a vhost webdav.demo.myserv-project.org if anybody wants to test it on windows | 20:41 |
| joerg | vmlintu, another idea would be to automount that stuff using davfs | 20:42 |
| joerg | vmlintu, and export that through samba | 20:42 |
| vmlintu | I wonder how fast that would be.. | 20:44 |
| vmlintu | I'll do some testing with the portal later this week and check the sources | 20:51 |
| joerg | vmlintu, I wouldn't use that as home dir... | 20:52 |
| joerg | it is a place in the web to share stuff with others... | 20:52 |
| joerg | not a place for heaps of dot files and app data :P | 20:52 |
| vmlintu | are you planning on acls for the shares? | 20:55 |
| joerg | vmlintu, well there are acls :P | 21:28 |
| joerg | vmlintu, you can edit/view them in a very uncomfortable way right now by right click on a file and "Edit ACL..." | 21:29 |
| joerg | vmlintu, they are automatically generated if you add a share to a profile | 21:30 |
| joerg | but from our experience, manually setting acls is overkill for students and especially teachers | 21:31 |
| joerg | they love you if you make things easy. | 21:31 |
| joerg | that's why the share concept exists: | 21:31 |
| joerg | if I want to share a folder I add it to my profile and select read/write for my friends and/or everybody | 21:31 |
| joerg | if I want to share a folder in a group, I add it to the group profile and select read/write for the group members | 21:32 |
| vmlintu | yes, it really should be kept simple for the users | 21:35 |
| joerg | vmlintu, got a demo server of your project as well? | 22:07 |
| vmlintu | joerg: not a public one at the moment | 22:09 |
| joerg | vmlintu, hmm, ok....is it easy to install? then I'd just check it out right now ;) | 22:12 |
| joerg | got a meeting concerning these things tomorrow..... | 22:12 |
| vmlintu | there's a setup tool here: http://github.com/opinsys/puavo-tools | 22:13 |
| vmlintu | it has been tested on clean lucid server installs only, though | 22:14 |
| vmlintu | the installation instructions for the whole thing are here: http://wiki.github.com/opinsys/puavo-users/ | 22:15 |
| vmlintu | I'm working on an actual website and demo server now.. just need to get some new servers installed | 22:17 |
| joerg | vmlintu, ah okay....well, I am too tired to follow all that instructions right now.... | 22:53 |
| joerg | doesn't look like if I could make that in 20 minutes... | 22:54 |
| joerg | I don't have more if I want to have 7 hours of sleep :) | 22:54 |
| vmlintu | 20 minutes is probably not enough if you haven't done it before | 22:59 |
| joerg | vmlintu, well, slapd and ldap auth is running here :) | 23:19 |
| vmlintu | did you use the script? | 23:20 |
| joerg | vmlintu, yes, your script....ages ago | 23:21 |
| joerg | you certainly remember | 23:22 |
| joerg | when I found an error which was not an error :) | 23:22 |
| vmlintu | I mean the scripts here: http://github.com/opinsys/puavo-tools | 23:22 |
| joerg | ah, no.....I was brushing my teeth :) | 23:23 |
| vmlintu | that does all the steps I wrote in the blog | 23:23 |
| joerg | vmlintu, just a hint to make it easier: apt-add-repository ppa:opinsys does the sources list thing and the key import :) | 23:37 |
| joerg | do I need that kerberos stuff? | 23:41 |
| joerg | I dont want it :P | 23:41 |
| joerg | and I don't want samba | 23:42 |
| vmlintu | kerberos is not required, but the setup script configures it now always | 23:42 |
