[01:07] <LaserJock> hi all
[01:14] <ace_suares> hi LaserJock !
[01:17] <LaserJock> ace_suares: hi, what's new in Edubuntu land?
[01:18] <ace_suares> I wish I knew
[01:19] <ace_suares> I am still fighting with win98 under ltsp to get my education programs working.
[02:32] <LaserJock> hi ogra
[11:48] <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
[13:19] <Feldegast> what state in the system in?
[14:02] <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/
[14:13] <jimjimovich> this seems to be very outdated
[14:14] <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
[14:15] <jimjimovich> i must say, i'm rather impressed with the 8.04 version
[14:15] <jimjimovich> very very slick
[14:16] <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
[14:17] <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
[14:18] <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
[14:19] <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)
[14:20] <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?
[14:21] <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
[14:22] <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
[14:23] <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
[14:24] <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
[14:25] <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
[14:26] <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 :)
[14:27] <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
[14:28] <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?
[14:33] <ogra> well, probably iptraf run locally on the server
[14:33] <ogra> but no, not explicitly
[14:33] <jimjimovich> ok, thanks
[14:34] <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 :)
