| ace_suares | hi LaserJock ! | 01:14 |
| LaserJock | ace_suares: hi, what's new in Edubuntu land? | 01:17 |
| ace_suares | I wish I knew | 01:18 |
| ace_suares | I am still fighting with win98 under ltsp to get my education programs working. | 01:19 |
| LaserJock | hi ogra | 02:32 |
| === ogra_ is now known as ogra | ||
| jimjimovich | does someone know of install and configure docs for ubuntu 8.04? I installed from the alternative cd but have no idea where to go from here | 11:48 |
| Feldegast | what state in the system in? | 13:19 |
| jimjimovich | actually, got it working. it would be nice if there were some docs ... maybe i'll have to make some :) | 14:02 |
| ogra | http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/ | 14:02 |
| jimjimovich | this seems to be very outdated | 14:13 |
| ogra | its from gutsy | 14:14 |
| ogra | one releae behind (the same handbook is installed on your system if you have edubuntu btw) | 14:14 |
| jimjimovich | i'm actually upgrading (redoing from scratch) a system that we put in place 2 years ago. | 14:14 |
| jimjimovich | oh, i thought it was from 6.06 | 14:14 |
| jimjimovich | i must say, i'm rather impressed with the 8.04 version | 14:15 |
| jimjimovich | very very slick | 14:15 |
| ogra | :) | 14:16 |
| jimjimovich | i think the main confusion with the docs is the change with the edubuntu server install | 14:16 |
| jimjimovich | now that you install it from the Ubuntu alt cd | 14:16 |
| jimjimovich | are most of the docs i'll find for gutsy configuration pretty much the same? | 14:17 |
| ogra | yeah http://wiki.ubuntu.com/HardyClassroomServer was supposed to explain that | 14:17 |
| ogra | most of the options are, yes | 14:17 |
| jimjimovich | that page is nice. just very hard to find | 14:18 |
| jimjimovich | ogra, you're one of the main developers, right? | 14:18 |
| ogra | yep | 14:18 |
| jimjimovich | i seem to remember talking to you 2 years ago when we first set up our lab | 14:18 |
| jimjimovich | so, question for you | 14:18 |
| ogra | heh, might be | 14:18 |
| jimjimovich | i have one major problem with our lab. we recently upgraded our internet gateway | 14:19 |
| jimjimovich | and it authenticates based on network cards (plus username and password) | 14:19 |
| jimjimovich | it's necessary for users to log into this gateway. the problem is with LTSP, once one person logs in, everyone is sharing their access | 14:20 |
| ogra | cant you do it by username ? | 14:20 |
| jimjimovich | is there some way to make each user have a different virtual network interface or do some spoofing to make each user look like a different MAC address? | 14:20 |
| jimjimovich | well, the gateway authenticates with username | 14:21 |
| ogra | identd shoudl give you the ability to tranfer the usernames o the GW | 14:21 |
| jimjimovich | but then uses the network device MAC address for keeping track of the session | 14:21 |
| ogra | and you cant switch that to usernames a well ? | 14:22 |
| ogra | *as | 14:22 |
| jimjimovich | well, the problem isn't authentication | 14:22 |
| jimjimovich | the problem is that this gateway counts user traffic | 14:22 |
| jimjimovich | that's why it binds to the network card after authentication | 14:22 |
| jimjimovich | but it's binding to the server network card | 14:23 |
| ogra | indeed, because the user session runs on the server | 14:23 |
| jimjimovich | exactly | 14:23 |
| ogra | thats pretty hard to do ... | 14:24 |
| jimjimovich | that's what i figured :( | 14:24 |
| ogra | you could run LDM_DIRECTX=True | 14:24 |
| jimjimovich | what would that do? | 14:24 |
| ogra | that would give you the client ip in the DISPLAY variable | 14:24 |
| ogra | it drops ssh encryption | 14:24 |
| ogra | similar to what XDMCP did but keeps the ssh tunnel for communicaion of the other services in place and does the password handshake throuh ssh as well | 14:25 |
| ogra | so its similar to XDMCP but adds some security | 14:25 |
| ogra | the advantage is that you get DISPLAY pointing to the client ip | 14:26 |
| ogra | oh, wait, you can get it easier | 14:26 |
| jimjimovich | what exactly is DISPLAY? | 14:26 |
| ogra | the LTSP_CLIENT variable holds the client ip | 14:26 |
| ogra | the display variable is what X uses to output its display :) | 14:26 |
| jimjimovich | ok. i guess the problem then becomes forwarding that info to the gateway | 14:27 |
| ogra | but use LTSP_CLIENT ... that way you can get the ip .... | 14:27 |
| ogra | with the ip you can do an arp lookup to get the actual client MAC | 14:27 |
| jimjimovich | though i think that info doesn't really help me, unfortunatly | 14:27 |
| ogra | now how you can spoof that is beyond my knowledge though | 14:27 |
| jimjimovich | mine too | 14:28 |
| ogra | but that way you have the MAC in your session available | 14:28 |
| jimjimovich | thought maybe you'd have heard of a similar situation. the tips you've given me might lead me in the right direction | 14:28 |
| ogra | no, i havent ... | 14:28 |
| jimjimovich | you haven't heard of any traffic accounting software that works with ltsp have you? | 14:28 |
| ogra | well, probably iptraf run locally on the server | 14:33 |
| ogra | but no, not explicitly | 14:33 |
| jimjimovich | ok, thanks | 14:33 |
| jimjimovich | and thanks for working on all this! it's really saving us a lot of time and money!!!! | 14:34 |
| ogra | i hope so :) | 14:34 |
