Ahmuckis there a way to audit user accounts on a system?00:26
Ahmuckunder a multi user system, isn't the user's directories supposed to be in-accessible from other users?00:31
mhall119Ahmuck: no00:38
mhall119they're usually not writable by other users00:38
Ahmuckreadable by others?00:40
mhall119the base of the folder is, yeah00:53
Ahmuckopening individual images/documents?00:54
Ahmuckopening of ?00:54
sbalneavEvening all01:55
Ahmuckok, back to user directories.  should user directories be "locked" to prevent traversing them?03:44
sbalneavAhmuck: Depends.04:02
sbalneavHow are you planning on sharing files?04:03
sbalneavAre you going to create separate "shared areas" for your people to share documents?04:03
Ahmuckwell, isn't "Public" a shared folder for public?04:03
sbalneavPublic, where?04:03
Ahmuckmy concern is students traversing home directories and "snooping" in other student's files04:03
sbalneavIn a users home dir?04:03
Ahmuckyes, it's here on our system by default04:04
Ahmuckeach user's home directory has a "Public" folder04:04
sbalneavyeah.  In my view, it's kinda dumb.04:04
sbalneavhere's how we do it.04:04
sbalneavEach user has their own primary group04:04
sbalneavso I'm sbalneav:sbalneav04:05
sbalneavmy home dir is mode 77004:05
sbalneavand I set the umask on the system to be 00704:05
sbalneavI create a /home/share04:05
sbalneavowned by nobody:share, which is a group I create, gid > 1000004:06
sbalneavIn the members of the group, I list all the userid's who need access to the share.04:06
sbalneavthe mode on the share directory is 277004:06
sbalneavi.e. the setgid bit is set.04:07
sbalneavthat way, any user who creates a file in that dir, the file is created group owned "share"04:07
Ahmuckunderstood, that i agree with04:07
sbalneavThat's how I've been sharing files at Legal Aid for 15 years.04:07
sbalneavit's always worked like a charm04:08
Ahmucki'll probally make it "public" rather than share04:08
Ahmuckso, can your users drop into each other's directory and see their files? open jpgs, etc.?04:09
Ahmuckcan they view what's in each other's directory?04:09
sbalneavno04:10
Ahmuckie, my love letter to Daniel, etc.04:10
Ahmuckhrm, i must have something wrong on my system then04:10
sbalneavNo you dont04:10
Ahmuckcreated a new user today, and that user can traverse any directory04:10
Ahmuckand view, open files, etc.04:10
sbalneavSure04:10
sbalneavby default, the umask's set to 00204:10
Ahmuckso ur saying that the procedure above is what you use to restrict that?04:10
sbalneavand /etc/skel's got too wide a permission.04:11
sbalneavWell, I don't use the graphical user creator04:11
Ahmuckneither do i04:11
Ahmucki use "adduser someuser"04:11
sbalneavsince I use LDAP for my account creation, I have custom scripts for adding users.04:12
Ahmuckah04:12
Ahmuckwell, i'll touch base with you tomorrow, i'm exhausted today04:12
Ahmuckfell asleep on the floor at work today, napping04:13
sbalneavlsbalneav@phobos:/etc/pam.d$ ls -la /etc/skel04:13
sbalneavtotal 3204:13
sbalneavdrwxr-xr-x   2 root root  4096 2009-10-28 18:55 .04:13
sbalneavyou'll want to start by toning down the permissions on /etc/skel, iirc04:13
sbalneavsince it uses those to creat the home dir.04:13

highvoltagekeffie_jayx: how are things?12:47
sbalneavMorning all14:48
highvoltagemorning sbalneav15:41
highvoltagesbalneav: I saw lts.conf.xlm for the first time yesterday... wow15:41
sbalneavwhich? In the docs you mean?15:45
sbalneavyeah15:45
sbalneavI've put a bit of work into that.15:45
sbalneavhighvoltage: So, you in Canada yet?15:45
highvoltagesbalneav: not yet, it will probably be another month or so before I'm there15:46
jbichais it cold in S Africa?15:46
sbalneavhighvoltage: excellent!  We should be deep in winter by that time :)15:47
sbalneavPing me when you're here, I'll gve you a buzz15:47
highvoltagesbalneav: I'll do so! I'm actually quite scared about the cold :)15:49
highvoltagejbicha: it's summer in south africa atm, so it's quite warm15:49
jbichaoh, I forgot15:49
sbalneavWell, it doesn't get down to -40C in Montreal like it does here.15:49
highvoltagejbicha: :)15:49
sbalneavMaybeeee -15 to -2015:50
highvoltageyeah coldest it gets in Cape Town is about 5C. coldest I ever experienced was about 1C when I was in Johannesburg last year15:50
jbichait's still around 30C/90F this week here15:51
highvoltagejbicha: where is 'here'?15:51
jbichaBahrain15:51
* highvoltage loves Bahrain15:51
jbichamy parents live in northern Alberta though15:51
jbichado you still plan on visiting Bahrain in a few months15:52
highvoltagejbicha: if there's time and if I can afford it15:52
highvoltagejbicha: I'd love to be able to take my father to a grand prix race, he's a big fan but has never been to one15:53
jbichaI expect to be living in the DC area next August so the climate should be more "normal" there15:53
effie_jayxhighvolt1ge: ping18:16
highvolt1geeffie_jayx: pong18:19
=== highvolt1ge is now known as highvoltage
effie_jayxhighvoltage: did you ever find that guide on teaching kids about free software?18:21
highvoltageeffie_jayx: no I didn't, at some point I'll have to do a thorough search on some old backups and get in contact with some people to see if they have it, I'm slightly worried that it might be gone forever18:23
effie_jayxhighvoltage: I should show you what my daughter is learning at school18:26
effie_jayxthe book is filled with WIN XP screenshots18:26
effie_jayxnothing against WIN XP SSs18:27
effie_jayxbut even if she tried any other product from microsoft she would be so lost with the ui changes18:27
effie_jayxshe is only 718:27
highvoltageeffie_jayx: ouch18:34
highvoltageeffie_jayx: yeah it's been a big topic in some places, should you teach someone how to use a specific OS, or should you rather teach them general concepts that are universal that they can use everywhere?18:35
highvoltageeffie_jayx: it's also a similar issue with openoffice vs ms office18:35
highvoltageeffie_jayx: in some institutions they spend lots of time teaching very specific parts of specific versions of ms office, then one day when the user has to move to another version or to another office suite, they're not sure how to figure out where to find the features18:36
LaserJockit's really hard even with different versions of MS Office18:36
LaserJockI've got MS Office 2007 here at work and I have no idea how to run the thing18:37
keffie_jayxyeah, but it is just scary how fosilized that can get18:45
keffie_jayxm dughter has been using linux as long as I have18:45
highvoltagekeffie_jayx: just saw your private dents... did you perhaps mean http://jonathancarter.co.za/files/static/docs/cookbook.html ?18:47
highvoltagekeffie_jayx: that was more meant towards teachers than kids :)18:47
keffie_jayxhighvoltage: right right18:49
keffie_jayxhighvoltage: right... but it is still good quality material19:03
highvoltagewow, welcome to everyone who joined!20:01
stgrabergreat to see more people in that room ;)20:02
ewaldmireI hope the group doesn't mind a follow-up question about LTSP-Cluster.... I'm just having a hard time finding more info about it:  Is it ready for production use?  Is there a place with screenshots/more info?20:02
highvoltageI wonder if there's already any software packaged that we should include for special-needs students20:03
stgraberit's deployed and used by over 60000 users mostly in Canada and it's getting to be used in companies as well20:03
stgraberdocumentation is mostly available on http://wiki.ltsp-cluster.org20:03
stgraberyou have a guide here "OpenVZ installation guide" on how to install it with OpenVZ, the same can be applied to physical servers20:04
stgraberthe code and bug tracking is done on Launchpad at https://launchpad.net/ltsp-cluster20:04
stgraberand we unfortunately don't have screenshot of our web UI (maybe because I'm not exactly proud of it ;)) but we probably should have some20:04
stgraberof both the current web interface and the new one on which highvoltage is working at the moment20:05
ewaldmirestgraber:  Got it - that's what I was looking for.  Sounds like I just need to install it and check it out.  :-)20:05
stgraberthe howto refers to the PPA as it was done for Jaunty, if you do it on Karmic, then you can simply use the regular package archive20:05
stgraberhighvoltage got all the packages in the archive with karmic20:05
rodneyorpheuswho should I talk to about getting a new package added to Edubuntu?20:07
stgraberrodneyorpheus: what software would that be ?20:09
stgraberI don't think we have a clear process there though we should establish a list of candidates and packages to work on during UDS20:09
rodneyorpheusSandbox, it's a 3D game design environment for kids20:09
highvoltagerodneyorpheus: it's the same process as getting a package into Ubuntu, although you could bring it to our attention by filing a needs-packaging bug in launchpad and subscribing us to it20:09
stgraberso sending me a list before UDS is probably the easiest20:09
highvoltagerodneyorpheus: ah :)20:09
stgraberhighvoltage: sounds like a great way of handling needs-packaging for education20:10
stgraberso just do as highvoltage said and I'll look at that list of bugs ;)20:10
LaserJockSandbox has been around for a while20:10
highvoltagerodneyorpheus: they send us announcements to our lists when they make new releases, it's been on my radar for packaging work for a while20:10
LaserJocklast time I looked at it needed some work to get it ready for packaging20:10
rodneyorpheusyeah, I was helping the devs and the GetDeb people make a debian package of the new version20:10
highvoltagerodneyorpheus: I've only become a motu last week, I'll add it to my list of things to package, but if anyone wants to beat me to it they are welcome :)20:10
rodneyorpheusso that's done now20:10
rodneyorpheusoh it's done20:10
Jesi-Idlethere is going to be a web interface to?20:11
rodneyorpheusand working wel20:11
LaserJockrodneyorpheus: so you have a source package?20:11
rodneyorpheussource is available, and c_korn from GetDeb already made a working ubuntu package20:11
stgraberrodneyorpheus: I don't see the package in Debian itself so it won't get imported automatically, though if you have a source package, that'll help us include it in Ubuntu directly20:11
rodneyorpheusplease have a look here20:15

Jesi-IdleQuestion: I'm a guy and I support what your doin, I'm not really sure what to say for this session, and I think that goes for most here and is why you're not getting many replies, I've never had a problem when it comes to gender equality and it's something I promote,   but I know that allot of my male friends really aren't that sensitive here, but they often don't realize it, what steps can one take to make sure the eviro20:27
Jesi-Idlenment doesn't seem so male-dominated, because I garuntee you many guys are completely oblivious20:27
Jesi-Idlesorry wrong channel20:27
HedgeMagerofl20:27
Ahmuck_anki would be a good one to package20:37
Lnslol20:53
LnsOk, do you need anything else from the store besides milk and bread? Oh, sorry wrong channel ;)20:53
Ahmuck_is everybody lost today?20:56
LnsAhmuck: have you seen my baseball?21:04
Sarten-XI'm trying to prepare a set of disks for use in a school in rural Africa. The donated machines there have only CD drives, not DVD. Is there a smaller version of edubuntu available, or an easy way to produce one?21:05
LaserJockSarten-X: would USB sticks be available at all?21:08
Sarten-XPossibly, but i'm not sure21:09
Jesi-Idleis you cant use any kind of USB/Thumb Drive.... I would suggest putting Ubuntu on a CD, installing it and then have them install the Edubuntu packages21:09
LaserJockthe DVD image can be burned to a USB stick using USB Startup Disk Creator21:09
Jesi-Idleprovided they have internet21:10
LaserJockand if not you might have to do something like AptOnCD21:10
Sarten-XWhat made Edubuntu so big? As I recall, 8.10 was only 300 megs or so...21:11
LaserJockSarten-X: it was just an addon Cd with the educational apps21:13
LaserJockSarten-X: it's now a full installation disk,so like Ubuntu + all the apps and language packs + LTSP rolled together21:13
Jesi-Idlehopefully it wont get so big we'll need to go blue-ray....... I'd like to see allot of stuff added....  but that may cause headaches21:15
Sarten-Xoh... so it no longer needs a separate ubuntu install first?21:15
LaserJockwell21:15
LaserJockSarten-X: exactly21:15
LaserJockit's all in one21:16
LaserJockSarten-X: we also added a Live session too where you can play around with it from the DVD without installing21:16
LaserJocksimilar to the Ubuntu Desktop CD21:16
Sarten-Xcan it still use a separate installation? Most of the machines wouldn't even run the desktop installer, and needed the alternate.21:16
LaserJockSarten-X: the alternate is there too21:17
LaserJockthe DVD has both21:17
LaserJockwhich is part of why it's so big21:17
Sarten-Xah... this is going to take more preparation than I was expecting...21:17
LaserJockwell, we made the DVD so that hopefully it would need *less*21:18
Sarten-Xoh21:19
Sarten-Xno no no...21:19
Sarten-Xit'll be less work for the person going over there...21:19
Sarten-Xjust I need to figure out logistics again21:19
Jesi-IdleI think the Live CD feature is going to be very important in getting people to try it.... is there/ will there be a WUBI version of Edubuntu?21:20
rodneyorpheusyes, WUBI would be great!21:21
rodneyorpheusthe biggest problem is getting people to do that first install21:22
rodneyorpheusonce they've crossed that barrier you're halfway there21:22
rodneyorpheusand WUBI is really good for that21:22
Sarten-Xheh21:22
Sarten-Xwubi is awesome21:22
Sarten-Xit has only one problem...21:23
Sarten-Xwhen I demonstrate it, I can only describe it as "magic"21:23
rodneyorpheushehe, so true21:25
rodneyorpheusI use it to teach my students about alternative operating systems, and they honestly can't believe  that it will work21:26
rodneyorpheusgood talking to you all - bye!21:45
wiehanwhere can I get an add-on iso for 9.10?21:55
LaserJockyou can't21:55
wiehanLaserJock: that isn't cool21:55
LaserJockyou need to either download the Edubuntu DVD or install via internet21:55
wiehanLaserJock: If I download the Edubuntu package from ubuntu 9.10 - How large download would that be megabyte wise?21:56
LaserJockwiehan: hmm, maybe 200MB21:57
wiehanI do not understand that, because Ubuntu is ~700mb + 200mb for edubuntu package, Edubuntu is 3.3gb?21:58
LaserJockwell21:58
LaserJockthere's a lot more to it21:58
LaserJockthe Edubuntu DVD includes both text-based and graphical installers21:58
wiehanLaserJock: I understant that more stuff is on the DVD so that you don't have to download it.21:58
LaserJockand there are a whole lot of language packs21:58
LaserJockUbuntu + educational apps is ~ 1GB21:59
LaserJockbut we have both graphical and text-based installers, which doubles that21:59
LaserJock2GB21:59
LaserJockthen we have about 1GB worth of language packs21:59
LaserJock3GB21:59
wiehanOk, would there really be any other advantage than downloading the DVD versus downloading the edubuntu package (Except for not having to download stuff I want later)21:59
LaserJockwell, if you already have Ubuntu installed, no, not really22:00
LaserJockwith the DVD you can install everything together pretty quickly and you can also run the educational apps from the DVD itself (for demos)22:00
wiehanwhat does the "not really" part implies? Because I really can't download that much now, but I really want the best for the kid I'm doing this for?22:01
LaserJockwiehan: I can probably cut it down22:01
LaserJockwiehan: what age?22:01
wiehanLaserJock: I really do not mind for the stuff you just mentioned22:01
wiehanAge 1222:01
LaserJockhmm22:02
LaserJockyou might try just installing ubuntu-edu-primary22:02
LaserJockI my machine that takes 218MB to download22:02
LaserJockunfortunately a lot of that is because of the KDE dependencies of KDE Edu22:03
LaserJockbut it's a very nice suite of software22:03
wiehanI would just use gnome?22:03
wiehanAre there some default KDE apps bundled with the standard gnome edubntu?22:04
LaserJockyes22:04
LaserJockthe KDE Edu suite comes with Edubuntu22:04
wiehanI understand22:04
LaserJockit's a lot to download but Gnome doesn't really have equivalent apps22:04
LaserJockif it was me I'd probably just install ubuntu-edu-secondary22:06
wiehanCan I just deliver one interesting comment: Edubuntu is Free, and Free is GREAT. Where does free-software have the most 'value'? The answer is simply put - in "poor" countries. "Poor countries" have expensive internet - then why only the DVD image? It makes no sense to some, like me, from where I come.22:06
LaserJockwiehan: well, its a complicated issue22:09
Jesi-Idlethe dvd image is great for that very reason, if internet isn't an option you need another method....the DVD is that method.... that hope usually is the CD22:09
Jesi-Idleor DVD can be sent to you22:10
LaserJockwiehan: we hope that people can share DVDs as much as possible22:10
Jesi-Idleif you cant download it22:10
Jesi-Idleit's complicated22:10
wiehanJesi-Idle: That is easy to say if internet has never been a problem.22:10
LaserJockthe addon CD was causing use quite a bit of issues22:10
LaserJockone problem was basically stigma, people didn't think Edubuntu was a distro because it was an add-on22:11
LaserJockfor instance, DistroWatch dropped us22:11
wiehanSo why not create specialzed downloads: Like Edubuntu-9.10-English22:11
LaserJockwe don't have bandwidth for it22:11
LaserJockinternet is not just an issue for poor countries22:12
LaserJockwe have only enough "hosting" space for 1 .iso file22:12
LaserJockwe decided to make the most of it we could22:12
wiehanDoesn't the same amount for of smaller downloads equal less than the same amount times 3.3gb of downloads?22:12
LaserJockno22:12
wiehanLaserJock: Ah, but isn't hosting space a difference issue than bandwaith?22:12
LaserJockbecause we currently ship ~ 100 languages worth22:13
Jesi-Idlewiehan: you can install the packages on top of Ubuntu, provided language isn't an issue.... that's 200some MB yeah but have you seen an Ubuntu ISO less than 200Mb?22:13
LaserJockif we made a CD for each22:13
LaserJockit's something like 50GB easily22:13
wiehanLaserJock: I understand, just curious22:13
LaserJockyeah, we put off doing a DVD for years22:14
LaserJock*specifically* because of poor countries22:14
LaserJockit was not an easy decision to make22:14
LaserJockanother big issue was that there was no way to demo Edubuntu using a Cd22:14
Jesi-IdleLaserJock: what is the storage and bandwidth limit you have to deal with?22:14
wiehanIt still is tough for so many people to download 3.3gb (it takes for ages and it's expensive) - it really is tough to understand if you live in a first world country an Internet in an legal right even...22:15
LaserJockJesi-Idle: Canonical will only host us if we limit ourselves to 1 .iso22:15
LaserJockwiehan: I understand22:15
LaserJockwiehan: hopefully if things progress we can do something better for people22:16
Jesi-Idleinternet isn't a legal right here, were I live....  USA22:16
wiehanJesi-Idle: Well, it still is dirt cheap and hell fast there22:16
LaserJockwe don't often have usage caps in the US, which is a real issue in a lot of countries22:17
LaserJockeven if it is slow here, we can just leave it downloading for however long it takes without a problem22:18
LaserJockmy parents have a 2GB cap/ month I think22:18
LaserJockso they couldn't download it22:18
Jesi-IdleWiehan: most of the time, like he said usage caps are the big difference......22:18
LaserJockanyway, I gotta run home22:19
wiehanbut your "slow" is really different than ours22:19
LaserJocknot always, you'd be suprised22:19
wiehanI still really appreciate what you guys are doing22:19
wiehankeep it up22:19
Jesi-IdleLaserJock: have you considered using other places to store filkes as well, like a mirrorbut a "mirror" per sey?22:19
LaserJockthe US can have some of the worst internet connections on the planet22:19
LaserJockJesi-Idle: well, we'd love to have just plain mirrors22:20
Jesi-Idleyep, when I had SB Yahoo, it went out all the time22:20
wiehanLaserJock: Do you often download stuff at a rate of 5kB/s22:20
LaserJockthe problem is with the Addon Cd nobody was taking Edubuntu seriously22:20
LaserJockwiehan: my parents do, usually 3kB/s22:20
wiehanWell..22:21
LaserJockthey just upgraded last week to a satellite internet thingy so they're no beyond a 28.8 modem :-)22:21
Jesi-Idlethe internet, one of our biggest resources yet one of our biggest limitations22:21
LaserJockwiehan: it depends on where in the US you are22:21
LaserJockwiehan: some places are very fast, but some places have horrible horrible phone lines that can't take DSL, etc.22:21
LaserJockJapan has some screaming fast internet22:22
LaserJockman I wish I had their connections22:22
wiehanAnd I wish I had yours22:22
Jesi-Idlesame, Japan has allot of the cool tech as well22:22
wiehanAnyways, I also need to go22:22
LaserJocka friend in Tokyo gets a 100MB/s optical T1 straight to his house for < $50 USD22:22
Jesi-Idle LaserJock: are you serious? that would be so expensive in the US22:23
LaserJockwiehan: thanks for stopping by22:23
LaserJockJesi-Idle: crazy I know, he has full mirrors of everything *buntu (archives, isos, etc.)22:24
Jesi-IdleI plan to set up a home server, if Fiver Oprics come out here, I'd be so happy.....22:24
Jesi-IdleI would to if I had that kind of connection :), what about Australia and China, do you know?22:25
