<nubae>
alkisg, hey... do you have a moment?
11:04
<alkisg>
Hi nubae, sure, but I'm also programming now so it might take me some time to answer
11:05
<nubae>
no problem... first question... do u think its worth me upgrading a school system running 10.04 LTS to natty?
11:06
ie... do u think a straight up dist-upgrade is going to work without too many complications?
11:07
<alkisg>
For the first question, (worth to update), imho no
11:08
For the second question (if it'll work), no idea
11:08
<nubae>
second question is, I've seen its possible to install vmware player/virtualbox in a fatclient environment... do u know if there is documentation on this soimewhere and have u ever tried it out?
11:08
<alkisg>
I've successfully tried installing vbox. I don't know if there are any docs for it.
11:09
Use gdebi for the installation so that it pulls dependencies
11:09
<nubae>
ok so u chrooted in and did it that way?
11:09
<alkisg>
I downloaded the latest .deb from virtualbox.org, chrooted with /proc etc mounted, and ran gdebi vbox.deb
11:10
<nubae>
coolio and did u try running win 7 in that or win xp?
11:11
<alkisg>
The teacher that asked me to helped him with that ran windows, yes, I'm not sure about the version, probably xp
11:11
<nubae>
so how did he install windows inside the fatclient?
11:11
<alkisg>
It doesn't matter then that it's a fat client, vbox files are in $HOME
11:11
So, normally
11:12
<nubae>
ah ok.. so i can just run vbox normally and install
11:12
cool
11:13
that was the main stuff thanks... I'll leave system as is then since fatclients seem to work fine here and install XP in vbox... its a tradeoff with the new IT teacher who refuses to believe open office is as good as the ms version
11:14
<alkisg>
how much ram do the clients have?
11:17
<nubae>
2 gig/1 gig
11:18
i want to take load off the server as its going to crash if he starts running vbox sessions on multiple desktops
11:19
Last question... in the primary they bought 10 netbooks with 500mb ram and intel celeron cpus... do u advise fat or thin?
11:20
<alkisg>
Server and network specs?
11:21
<nubae>
gigabit network
11:21
<alkisg>
Generally with <500 I advice thins, with > 500 fats, but for exactly 500 it depends on the server cpu + network
11:21
<nubae>
rolled down to 100mbit in primary router
11:21
<alkisg>
If the server is lame though, fat clients with e.g. lxde would go better
11:22
<nubae>
server cpu xeon quad
11:22
<alkisg>
How many clients?
11:22
(thins only)
11:22
<nubae>
approx 25
11:23
<alkisg>
And client cpu MHz?
11:23
<nubae>
the netbooks?
11:23
<alkisg>
Yes
11:23
<nubae>
ill go check... back in 5
11:23
<alkisg>
nubae: check the processor type better
11:24
So that we get its benchmark from http://www.cpubenchmark.net/common_cpus.html
11:25
<nubae>
amd sempron 1.5 ghz/1 gig ram
11:25
was wrong about ram
11:25
<alkisg>
Surely fats then
11:26
<nubae>
they currently are fats but not ltsp based... im better connecting them to the ltsp network, dont u think?
11:26
i mean they are running ubuntu natty fat
11:26
<alkisg>
Yes, less maintainance. You might want to add a second nic to your server, to have 2 gbps, if needed.
11:27
<nubae>
yep
11:28
well i'll try it as u suggested and let u know how it goes... wasnt too impressed with natty myself either... I will wait for next lts release
11:29
ah last last thing... in documentation it talks about installing ltsp_chroot, do u recommend that, is there an advantage or can I build up the fats the old fashioned way?
11:30
<alkisg>
Do you want to build the fats (ltsp-build-client) or install vbox (ltsp-chroot)?
11:30
<nubae>
vbox, already have the fats
11:30
though really need 2 versions
11:31
so maybe use this one for primary
11:31
and make a new one with vbox
11:31
<alkisg>
Just remember to mount /proc etc in case vbox needs them
11:31
<nubae>
ok
11:32
I'll try vbox on the current fats mounting /proc etc as u suggest then
12:02
<andygraybeals>
i've been wondering, ubuntu 10.04 server expires in 2014; ubuntu desktop before that; i'm running ubuntu server with ubuntu-desktop package on top and ltsp... so is this okay until 2014, or am i thinking incorrectly?
12:10
<alkisg>
April 2013 (Desktop), April 2015 (Server)
12:11
That means that your desktop packages, e.g. firefox, won't be updated for security vulnerabilities
12:11
But it still leaves you 1 year to update to the next LTS, 12.04
12:11
Updating every 2 years doesn't sound often to me...

<andygraybeals>
alkisg, aah so your going to upgade to 12.04 ?
13:18
<alkisg>
Yes, or clean install
13:18
<andygraybeals>
yea, i guess i meant clean install
13:19
yea, i just want to do what you do :)
13:20* alkisg goes to take a nap :D
13:20
<andygraybeals>
;)))
13:25
<nubae>
hmmm how does one force proc to umount again?
13:27
ah -l that was it
13:30
<alkisg>
You shouldn't ever need to force unmount
13:30
That was probably proc/binfmt still mounted
14:03
<nubae>
yep
14:04
question about users and groups every user should have their own group right so in /etc/passwd it looks like:
14:04
kdancer:x:1008:1008:Kathy Dancer,,,:/home/kdancer:/bin/bash
14:05
because here everything is all over the place, with most users being in one group
14:05
but that not always being the case
14:05
think I inherited some nasty problems
14:07
ugh... /etc/group looks even crazier :-/
14:13
question about defaulting printers... on thin clients defaults are correct, but fatclients have copied those defaults, can I just go ahead and change them?
14:13
in the fatclients?
