| ogra | nubae1, i dont like kiwi because it completely breaks the concept of ltsp5 to integrate deeply with the distro and through that improve the upstream packages, because it reimplements ltsp4 on a different level and because it prevents any kind of upstream contribution through suse users ... | 08:58 |
|---|---|---|
| ogra | nubae1, it has *noting at all* to do with paths but with selfish attitude and breaking of concepts | 08:59 |
| ogra | nubae1, its great that it exists for the users wanting it but its a 100% fork | 08:59 |
| alkisg | ogra, if I made something similar with ubuntu, i.e. a live ubuntu dvd with ltsp preinstalled and ready to function, and with some edu* packages installed, would I be able to redistribute it without having to call it with a name other than "ubuntu"? | 09:02 |
| highvoltage | ogra: someone was arguing yesterday that it isn't a fork, but I agree with you that it's clearly a fork. | 09:30 |
| ogra | well, i dont mind the fork that much, but the rest | 09:31 |
| ogra | good blog post btw :) | 09:32 |
| tsurc | good morning all :) | 09:32 |
| highvoltage | thanks ogra, I didn't know how you'd react to it (or anyone else for that matter) | 09:35 |
| highvoltage | but I just needed to say something about it at least | 09:35 |
| tsurc | does anyone know the reasons for having defining a terminal in the /etc/hosts file? I'm having a problem where if our internal dns server is down we get a grey screen | 09:47 |
| ogra | ltsp5 doesnt use DNS at all, ltsp4 where you actually needed that for the highly insecure XDMCP connection it uses was never supported in ubuntu | 10:04 |
| tsurc | ah sorry I should have been clearer, I'm on a box with ltsp 4.2 on, my question was less about fixing the problem (as I soon fixed it by updating the /etc/hosts file and restoring internal dns) but more about understanding why this would happen | 10:10 |
| tsurc | I guess I'm on the wrong channel... #ltsp? | 10:11 |
| ogra | well, even in #ltsp its a matter of luck to get ltsp4 support, ltsp4 is dead since 4 years | 10:12 |
| ogra | the last security fixes were in 2005 ... running ltsp4 anywhere is just adding a big security hole to your system | 10:13 |
| tsurc | like I said I was more about curiosity and better understanding that support :) | 10:14 |
| tsurc | maybe its one of those things that I needn't concern myself with | 10:15 |
| ogra | XDMCP looks up the hostname and IP on connect | 10:15 |
| ogra | if it cant find either it cant start | 10:16 |
| ogra | well, it can start but not connect to any remote display manager | 10:16 |
| ogra | so what you see is the local start of the X server ... | 10:16 |
| tsurc | ah right, so if a client is not in /etc/hosts... and not in DNS (read they weren't in dns anyway, but I guess the xdmcp server was expecting "some" response as opposed to "no" response) then the xdmcp server will not allow the connect | 10:18 |
| ogra | right | 10:18 |
| tsurc | and the difference in the way ltsp5 does it? | 10:18 |
| ogra | it uses ssh | 10:19 |
| ogra | not XDMCP | 10:19 |
| tsurc | so you tunnel the users x server session to the client machines x server | 10:20 |
| ogra | right, which means for example you dont need to have X running on the server | 10:21 |
| ogra | and you cant run a tcpdump from anywhere in your network and produce screenshots of password captures from it like with XDMCP | 10:21 |
| tsurc | ah cool :) | 10:22 |
| tsurc | but you have the overhead of everything running through ssh... small price to pay though I guess :) | 10:23 |
| ogra | you can switch encryption off for the actual X traffic with LDM_DIRECTX=True in lts.conf | 10:24 |
| tsurc | yeah I read that one somewhere | 10:24 |
| tsurc | and this makes ldm revert to xdmcp? | 10:24 |
| ogra | that will only keep the password and feature communication (ltspfs etc) in ssh, but your payload X traffic will be redirected through a plain DISPLAY forwarding | 10:25 |
| tsurc | nice :) | 10:25 |
| ogra | so at least the password handshake is more secure than XDMCP ... i wouldnt advise my users to do any onlinebanking in that ode though ;) | 10:25 |
| tsurc | your all very very clever people.... I really wouldnt know where to start, lol | 10:25 |
| ogra | *mode | 10:26 |
| tsurc | thank for your help :) | 10:32 |
| alkisg | ogra: if I took the ubuntu desktop cd, and installed a lot of educational apps into it (from the ubuntu repositories), and installed ltsp-server and build an ltsp chroot, and used dnsmasq instead of dhcpd3-server to be able to function as a live-ltsp-server with a dynamic IP, and produced a live dvd with all that, would I be permitted to redistribute the .iso and still call it Ubuntu? Or is what I'm thinking yet another distro? | 13:07 |
| ogra | ubuntu-edu-ltsp-remix ? :) | 13:07 |
| alkisg | Yeah, sure :) | 13:08 |
| alkisg | I can find hosting, and I think it'll be useful, but I don't want to get into trouble with the naming thing... | 13:08 |
| ogra | http://www.canonical.com/projects/ubuntu/unr -> see the "what is a remix" section | 13:08 |
| alkisg | Ahhh ok looking... | 13:08 |
| alkisg | Yup, ogra, I think you're the goddad (if that's what it's called) of my remix :) "ubuntu-edu-ltsp-remix" it is! | 13:11 |
| ogra | :) | 13:11 |
| alkisg | I think doing a remix isn't too hard, is it? | 13:11 |
| ogra | well, depends how you do it :) | 13:12 |
| alkisg | Hmmm any links for a how-to or something? | 13:12 |
| ogra | just changing the iso is quite easy | 13:12 |
| ogra | look for LiveCDCustomization on the wiki | 13:13 |
| alkisg | Thanks ogra! I think I just found out what to do in the summer vacations... :P | 13:13 |
| ogra | https://wiki.ubuntu.com/MobileTeam/Mobile/HowTo/ImageModification has some hints about how to edit a squashfs | 13:13 |
| ogra | (note this doesnt use an iso, you need the mkisofs magic from the wiki howto for isos) | 13:15 |
| * alkisg is reading https://help.ubuntu.com/community/LiveCDCustomization ... | 13:15 | |
