I have got entry in /opt/i386/etc/lts.conf [172.16.0.27] PRINTER_1_DEVICE=/dev/lp0 PRINTER_1_TYPE = P but terminal not starting anymore. Then, when I nmap'ing this machine (during start), port 9100 is open and in few seconds no port 9100 open. Sorry for my english.
| |
| 07:05 | Without this entry terminal starting normally.

| 08:50 | <Hyperbyte> eh... I just subscribed to the ltsp-discuss mailing list, the first e-mail I received has the subject "OMGZORS!! WTF!! nsfsmount: need a path"
| |
| 08:51 | Have I just picked a wrong time to join the mailing list, or is this representative for the usual communication in the list? :-)
| |
| 08:52 | <bauerski> Hyperbyte: wait a moment.
| |
| 08:53 | <knipwim> perhaps the same dude as yesterday?
| |
| 08:53 | the unfriendly one?
| |
| 08:54 | <Hyperbyte> knipwim, hehe, you mean the one who said I'm a useless cunt? :-D
| |
| 08:54 | <bauerski> http://pastebin.com/LGFn8Ke4
| |
| 08:54 | <knipwim> yeah
| |
| 08:55 | <Hyperbyte> That's what I thought. :-)
| |
| 08:55 | bauerski, between the []'s you specify the mac address, not the IP address
| |
| 08:56 | <bauerski> OK. I'll try in the moment.
| |
| 08:56 | <Hyperbyte> Something like [00:e0:c5:45:46:16], rather than [172.16.0.27]
| |
| 09:04 | <bauerski> Still the same. Retrieves the address from dhcp and freezes after: filename: ltsp/i386/pxelinux.0
| |
| 09:08 | <Hyperbyte> And if you comment out the last three lines, the client does boot?
| |
| 09:08 | <bauerski> Yes
| |
| 09:14 | But when nmap'ing host, client boot. http://pastebin.com/VMFRtBPf

| 11:54 | <Hyperbyte> IAssBurgers, what do you want them to save, specifically? And which distro/version are you using?
| |
| 11:55 | Oh - wait a second
| |
| 11:55 | I forgot
| |
| 11:56 | You're the guy who called me a useless cunt yesterday. Guess you're on your own. :-)
| |
| 11:56 | andygraybeal, what's up! :-)
| |
| 11:57 | <andygraybeal> heya Hyperbyte. i'm working on using 'liferay' cms .. how about you?
| |
| 11:58 | <Hyperbyte> Working on the CMS/automation system they have here... my "todo"-list for that system insanely huge... 1st of april I'll be getting a new colleague though, so it'll become managable then.
| |
| 11:58 | Should've said CRM instead of CMS by the way
| |
| 11:58 | <andygraybeal> that's bad ass, i hope you two get along.
| |
| 11:58 | aah CRM.. *run away* *run away* *run away!!!!*
| |
| 11:58 | <Hyperbyte> Heh - we will... he's one of my best buddies, we know eachother from ICT college.
| |
| 11:58 | :-)
| |
| 11:59 | Run away? Why?
| |
| 11:59 | <andygraybeal> omg, crms?!!?!!?
| |
| 11:59 | <Hyperbyte> Customer database/relation management?
| |
| 11:59 | <andygraybeal> yes yes, i wouldn't go near them!!
| |
| 11:59 | i'm having a hard enough time with plain regular apps.
| |
| 12:00 | but, i mean, congrats on doing it! i support you.
| |
| 12:00 | which one have you chosen to use?
| |
| 12:01 | <IAssBurgers> well hyperbyte you are pretty damn useless, this channel is here for people seeking knowledge
| |
| 12:01 | <Hyperbyte> Well, I'm calling it CRM because I don't know the proper term for it
| |
| 12:01 | <IAssBurgers> I came and asked you and all you did was act like an elitist jerk
| |
| 12:01 | I figured out on my own
| |
| 12:01 | with some help from the email list
| |
| 12:02 | I have thick clients booting again
| |
| 12:02 | Just havent figured out how to get them to save or sync when I shut down
| |
| 12:02 | <Hyperbyte> IAssBurgers, check the IRC logs. You'll find I'm very helpful & willing to help. Too bad you won't get any first-hand experience with that from me anymore. Also - this is the last thing I'm gonna say to you.
| |
| 12:02 | <IAssBurgers> But I did get swap file working
| |
| 12:02 | Sir I dont keep irc logs, only fgts log irc conversations
| |
| 12:02 | <Hyperbyte> andygraybeal, basically, it's an application I've made myself... it manages lots of work processes here, clients, travels, bookings, travel managers, etc....

| |
| 12:03 | <alkisg> The cunt etc stuff will always be online for everyone to see
| |
| 12:03 | <andygraybeal> Hyperbyte, aah cool, yea, i good luck :)
| |
| 12:03 | <Hyperbyte> andygraybeal, it's my long-term project here. Been building it for five years or so.
| |
| 12:04 | And people constantly want extra features, and stuff... ;-)
| |
| 12:05 | <andygraybeal> i've had a look at tigercrm and others, just to keep them in my peripheral, nothing more.
| |
| 12:06 | IAssBurgers, when you say 'sync' do you mean ... like saving files? on my fat clients, i mount a share from the server.. and save the data to it like that. i wonder though, your probably way more advanced than me and already know this and you actually mean something else.
| |
| 12:06 | <Hyperbyte> Well, years back we made concious decision that we wanted a system that facilitated and automated communication with customers, volunteer travel guides and external relations, without losing the personal touch. With those goals, you really need something custom-made.
| |
| 12:07 | <IAssBurgers> well yeah like say, I change my home page in the browser, set some shortcuts on a box, w/e when I reboot, the thick client comes up ok, but none of those changes are saved
| |
| 12:07 | <andygraybeal> ah that is all inside of your image that you build
| |
| 12:08 | <IAssBurgers> no it should have autosave option
| |
| 12:08 | it doesnt, so derp
| |
| 12:08 | * Hyperbyte grins madly. :-D | |
| 12:08 | <IAssBurgers> dont go there bro
| |
| 12:08 | <andygraybeal> hm.. lltsp-update-image .. i think is what you'll need to do to work like this.
| |
| 12:09 | errrr too many ll's.
| |
| 12:09 | everytiime you want to make a change to your image, you have to run that command.
| |
| 12:09 | <IAssBurgers> anyway to make that happen when the ltsp fat client shutsdown?
| |
| 12:09 | <andygraybeal> you have to do that inside a chroot, not on the client.
| |
| 12:10 | <IAssBurgers> fuck that
| |
| 12:10 | it should have option to do that
| |
| 12:10 | <andygraybeal> well, why? chroot works fine.
| |
| 12:10 | <IAssBurgers> why the hell would o chroot from the fat client every time I shut down?
| |
| 12:10 | lol
| |
| 12:10 | use your brains, your the smart ones here
| |
| 12:10 | figure it out
| |
| 12:11 | <andygraybeal> you wouldn't, you'd build your chroot the way you want it.. then update your image. easy.
| |
| 12:11 | <IAssBurgers> lord
| |
| 12:11 | ok so yeah thats a great idea in fact, why do computers save data at all? maybe they should all reboot and come up as a static image
| |
| 12:11 | <andygraybeal> you wouldn't chroot from the fat client at all, i don't think you understand.
| |
| 12:12 | i don't think you understand how to implement the environment
| |
| 12:12 | <IAssBurgers> no you dont get what Im saying
| |
| 12:12 | derp, I know how to chroot and make changes and update the image
| |
| 12:12 | what I asked, and let me ask it again so you understand
| |
| 12:12 | I want any changes I make ON the fat client, to save to the image automatically when I shut down
| |
| 12:12 | <andygraybeal> well, i don't know if it works like that.
| |
| 12:13 | <IAssBurgers> I know, thats what Im sayin
| |
| 12:13 | would be nice feature to ad
| |
| 12:13 | <andygraybeal> i think all the changes need to be made on the chroot, then update t he image.
| |
| 12:13 | ah then, there you have it. feature request :)
| |
| 12:13 | but i don't see a need for it.
| |
| 12:13 | <IAssBurgers> look, hyperbyte are you a developer of ltsp?
| |
| 12:13 | <andygraybeal> i think using chroot to update the image is just fine.
| |
| 12:13 | <Hyperbyte> IAssBurgers, no.
| |
| 12:14 | Oh, I forgot. I'm not talking to you. :-D
| |
| 12:14 | <andygraybeal> i wouldn't want people updatnig their own image from within the image itself. that gets haphazard.
| |
| 12:14 | <Hyperbyte> I can tell you this: http://www.middelkoop.cc/yrdiw.jpg
| |
| 12:14 | <IAssBurgers> sure Im not complaining about chroot procedure
| |
| 12:14 | mmhmm..
| |
| 12:14 | there is a way to do it
| |
| 12:15 | <andygraybeal> well, i think the idea is central control of the image... done with the chroot.
| |
| 12:15 | <IAssBurgers> well thats a great feature too
| |
| 12:15 | but Ive got multiple machines here that I personally use, its not a classroom
| |
| 12:15 | <Hyperbyte> Great thing is: LTSP has the best of both worlds combined.
| |
| 12:16 | Too bad I'm so useless... :(
| |
| 12:16 | <IAssBurgers> well, thinclient loads the os off the main system which is nice, but it also sucks balls using the cpu, ram, sound on the server
| |
| 12:17 | <andygraybeal> i guess, i figure it's just something i've gotten used to IAssBurgers. I think that i'm still getting used to it.
| |
| 12:17 | I just recently starting using fatclients.
| |
| 12:17 | <IAssBurgers> would be nice to load the os the way thinclient does, AND use local cpu, ram gpu the way thin client images do
| |
| 12:18 | thick client images, sorry my bad
| |
| 12:18 | thick/fat w/e same thing
| |
| 12:18 | <andygraybeal> i think the devs are planning what you are saying to the feature set.
| |
| 12:18 | <IAssBurgers> ltsp 6?
| |
| 12:18 | <andygraybeal> i can't say.
| |
| 12:19 | <IAssBurgers> hey hyperbyte, sorry for being a douchebag, I was up for 50+ hours
| |
| 12:19 | <alkisg> Wow, I thought I wouldn't speak to IAssBurgers until he apologized to Hyperbyte, not sure if I should help him now that he did
| |
| 12:19 | <andygraybeal> wow 50 hours :)
| |
| 12:20 | <Hyperbyte> IAssBurgers, sometimes I have horrible days as well. I still don't go around on the internet calling random people who are trying to help me "useless cunts".
| |
| 12:20 | <andygraybeal> he said sorry, take it. don't keep arguing
| |
| 12:20 | <Hyperbyte> Apology accepted, but being up 50+ is no reason to be a douche.
| |
| 12:20 | <andygraybeal> lets get over it, i hate to see drama in this channel.
| |
| 12:20 | no buts! :P
| |
| 12:21 | i need more coffee guys :)
| |
| 12:21 | <Mava> mm.. coffee <3
| |
| 12:21 | <IAssBurgers> i know....
| |
| 12:22 | I was raging coz I couldnt figure out how to thick client
| |
| 12:22 | but I know now,
| |
| 12:22 | artista_frustrad has joined IRC (artista_frustrad!~fernando@200.247.43.2) | |
| 12:22 | <IAssBurgers> In debian squeeze you ltsp-chroot --mount-proc
| |
| 12:22 | then apt-get install and make w/e changes you want, create users etc
| |
| 12:22 | THEN you ltsp-update-image
| |
| 12:23 | voila, generates the image
| |
| 12:23 | <andygraybeal> yea, i can't remember what dev was talking about an interface to make changes to chroot, or even if i remember correctly that being what they said.
| |
| 12:23 | <IAssBurgers> also u can set the swap file enabled and setup a conf for that
| |
| 12:23 | <Hyperbyte> IAssBurgers, I know where you're going wrong.
| |
| 12:23 | <IAssBurgers> ?
| |
| 12:23 | <Hyperbyte> And I will tell you.
| |
| 12:24 | <andygraybeal> Mava, :) mmm mmm
| |
| 12:24 | <IAssBurgers> well I dont know where I could be going wrong, its working
| |
| 12:24 | <Hyperbyte> Before I do that, I would ask you to please think about that everyone in this channel is here to help you, voluntary... we like sharing knowledge. I would love for you to participate in this, but please - start being a little more laid back. :-)
| |
| 12:25 | <IAssBurgers> ah, yes
| |
| 12:25 | <Hyperbyte> Have some coffee, relax... like Andy. ;-)00000000
| |
| 12:25 | Now here's where you're going wrong:
| |
| 12:25 | Even though fat clients don't run any software on the server, they're still using the user database from the server, and storing user files on the server.
| |
| 12:26 | You have to create the fat clients users on the server, not inside the chroot.
| |
| 12:26 | <IAssBurgers> also had some trouble getting sound to work, but that had nothing to do with ltsp, had to manually install the modules for this ESScrapware soundchip
| |
| 12:26 | orly
| |
| 12:26 | <andygraybeal> i have to install extra modules for my asus eeebook
| |
| 12:26 | too
| |
| 12:26 | <IAssBurgers> yeah I noticed that
| |
| 12:27 | only one of my user accounts was automatically in the fatclient image
| |
| 12:27 | but I have the same user account on my thick client that I login with as my server
| |
| 12:27 | and its not saving anything when I shut down
| |
| 12:27 | <Hyperbyte> You shouldn't have any users in the fatclient image. You should have them on the server. When you login with LDM, the user on the server is created on the client, and their home is mounted from the server.

| 12:27 | <IAssBurgers> um
| |
| 12:28 | no it doesnt work like that, for me, im confused, let me clarify...
| |
| 12:28 | <andygraybeal> yes, home is auto mounted, you can mount other things manually also (like i do /srv)
| |
| 12:28 | <IAssBurgers> I cannot login to the image unless I chroot and create users
| |
| 12:28 | <alkisg> That's because you're using gdm instead of ldm
| |
| 12:28 | <IAssBurgers> ahhh
| |
| 12:29 | <alkisg> Anyway, I can't read more of orly wut etc, bb
| |
| 12:29 | <andygraybeal> ldm is awesome it's orange and it looks bad ass!
| |
| 12:29 | <IAssBurgers> well ldm is installed on both the image and the server
| |
| 12:29 | I guess Im just not using it atm
| |
| 12:29 | alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Quit: Leaving.) | |
| 12:30 | <IAssBurgers> so would I have to make ldm the default on the server to achieve this?
| |
| 12:30 | <Hyperbyte> IAssBurgers, LDM is installed on the server? If that's the case, then you have screwed up your installation badly. You flipped yesterday when I said this, but I'm gonna say it again: reinstall.
| |
| 12:30 | You shouldn't have LDM on the server, just on the client.
| |
| 12:30 | <IAssBurgers> lemme check, one sec
| |
| 12:30 | deviant:/opt/ltsp/i386# aptitude search ldm
| |
| 12:30 | i ldm - LTSP display manager
| |
| 12:30 | i A ldm-server - server components for LTSP display manager
| |
| 12:31 | yup its installed on the server
| |
| 12:31 | <Hyperbyte> I'm gonna get back to work here, lots to do... but let me give you some real good advice (and I know you don't like it, but please take it): install Ubuntu, configure fat clients and see how they work - experiment with them.
| |
| 12:31 | <andygraybeal> ot: grr one of my vm's isn't coming up.. i hate this.
| |
| 12:31 | <IAssBurgers> well it sort of installed it automatically when I install ltsp-server-standalone
| |
| 12:31 | <Hyperbyte> Once you learn how it works with Ubuntu, you'll have an easier time understanding how it should work on Debian.
| |
| 12:31 | <IAssBurgers> I refuse to use ubuntu
| |
| 12:32 | ubuntu server is fine, but I wont use ubuntu-desktop
| |
| 12:32 | <andygraybeal> i don't t hnk you need to use ubuntu-desktop you can use somethign else.
| |
| 12:32 | <IAssBurgers> besides, I have an established debian server
| |
| 12:32 | <andygraybeal> i know people in here use lxde and others.
| |
| 12:32 | <IAssBurgers> runs my squid and webserver, sql stuff
| |
| 12:32 | <Hyperbyte> It won't kill you to try it, just to see how it works. I frequently install all kinds of distros to see how things work. My LTSP server was RedHat before I settled on Ubuntu.
| |
| 12:32 | Either way, back to work. --->
| |
| 12:33 | <IAssBurgers> k
| |
| 12:33 | thanks
| |
| 12:33 | <Hyperbyte> You're welcome.
| |
| 12:33 | :)
| |
| 12:34 | <andygraybeal> don't be mean to me, but i'm an idiot and i got it to work on ubuntu no probs.. just followed the docs on ubuntu.com: https://help.ubuntu.com/community/UbuntuLTSP
| |
| 12:34 | i install it on ubuntu server, then run with the fatclient install.
| |
| 12:34 | i do use ubuntu-desktop inside my image, but that is because i don't mind the 10.04 way of doing things.
| |
| 12:35 | soon, i won't be able to do that though :(
| |
| 12:35 | hopefully i can use the failback-gnome.
| |
| 12:35 | i haven't tested that stuff yet, i've been waiting to hear what others report back.
| |
| 12:37 | <IAssBurgers> yeah in debian-squeeze the only issue I had actually booting the fatclient was that shitty network-manager garbage breaking my connection during boot
| |
| 12:40 | <andygraybeal> ot: omg, rebooting my vm server.. i can hear my heartbeating...
| |
| 12:40 | <IAssBurgers> lol
| |
| 12:40 | <andygraybeal> i have too much anxiety for this.
| |
| 12:41 | <IAssBurgers> well ltsp-server-standalone and fatclient is not the same in debian as it is in ubuntu
| |
| 12:41 | there is no ltsp-build-image --fatclient option
| |
| 12:41 | you just build the image
| |
| 12:41 | but set fatclient=true in the lts conf before u build
| |
| 12:42 | other than that It looks the same

| |
| 13:39 | <Hyperbyte> How old is 11 years in Freenode terms anyways?
| |
| 13:40 | <jammcq> I think the formula is: Multiply by 9, divide by 5, add 32
| |
| 13:41 | <Hyperbyte> 51,8, wow!
| |
| 13:41 | <andygraybeal> wow 11 years, for real?
| |
| 13:41 | <jammcq> yeah, that's about right
| |
| 13:41 | <alkisg> Wow, I'm 100 years old in freenode terms :P
| |
| 13:41 | <Hyperbyte> Haha
| |
| 13:41 | <alkisg> Happy birthday LTSP, thanks jammcq :)
| |
| 13:41 | <jammcq> alkisg: you don't look a day over 90
| |
| 13:41 | <Hyperbyte> alkisg, Freenode itself isn't even that old in Freenode terms! ;-)
| |
| 13:41 | <jammcq> we were using freenode since before it was called freenode
| |
| 13:42 | <Hyperbyte> This channel is only one year younger than Freenode and it's predecessors itself, according to Wikipedia.
| |
| 13:43 | * Hyperbyte high fives jammcq :-D | |
| 13:43 | <Hyperbyte> Wait - no - I'm counting completely wrong here
| |
| 13:44 | About five years younger.
| |
| 13:47 | jammcq, 11 years ago, did you ever dream secretly that LTSP would power hundreds and thousands of thin clients around the world? ;-)

| 14:17 | <alkisg> Since the system certificate is also for 10 years, I think I'll go for that
| |
| 14:18 | <neyder_> Hi!
| |
| 14:18 | <alkisg> (maybe reusing the system certificate itself, instead of generating ours...)
| |
| 14:18 | <neyder_> how can i restart epoptes client?
| |
| 14:18 | <alkisg> neyder_: you just run /usr/sbin/epoptes-client
| |
| 14:18 | It'll automatically kill the other instances of the same user
| |
| 14:18 | <stgraber> alkisg: well, the snakeoil certificate is actually a problem with an expiry of 10 years, that's why we usually recommend generating a new one instead of using it
| |
| 14:19 | <alkisg> stgraber: is that an advice towards system administrators, or towards packages?
| |
| 14:20 | I mean, if epoptes uses the snakeoil certificate, and the system administrator generates another for 40 years, we wouldn't mind,
| |
| 14:20 | ...anyway
| |
| 14:20 | <stgraber> alkisg: administrators usually. The snakeoil is usually used by apache where the client (a web browser) will clearly show that the certificate expired making it easy for the administrator to go and re-generate it.
| |
| 14:21 | <alkisg> It'll be much quicker to just increase the certificate life
| |
| 14:21 | And we can consider on another release if we want to use the system snakeoil instead of generating our own
| |
| 14:21 | I wonder if we could use the ssh keys as certificates... since the chroot already has the server keys
| |
| 14:21 | <neyder_> gracias!
| |
| 14:21 | <stgraber> I kind of like having a separate CA for epoptes especially if we eventually want to have the central server stuff with the admin authentication using SSL client certificates
| |
| 14:22 | like I demoed at the hackfest
| |
| 14:22 | <alkisg> neyder_: you're welcome
| |
| 14:22 | <stgraber> so yeah, I think the easiest is to bump the expiry to something big enough that we won't ever have to care about it :)
| |
| 14:23 | (sadly SSL doesn't support certificates without expiry)
| |
| 14:23 | <alkisg> stgraber: about the "cannot find an appropriate pixmap format" problem, what's your color depth? 24?
| |
| 14:23 | Ah just saw your answer
| |
| 14:23 | <stgraber> alkisg: I replied in the bug, yeah it's 24bit at 1024x768 with a cirrus video card
| |
| 14:23 | <alkisg> OK, it seems like I finally have to try out KVM :)
| |
| 14:24 | It's an xvnc4viewer bug though... and x11vnc -24to32 was supposed to work around it
| |
| 14:24 | <neyder_> to make epoptes work (no ltsp) with mixed distros (lucid, maverick, oneiric) you should first install the server, after on clients put the ip on /etc/default/epoptes-client and las copy the certificate "sudo /usr/sbin/epoptes-client -c" ;) Thanks!
| |
| 14:25 | <alkisg> neyder_: or you could put "server" in /etc/hosts
| |
| 14:25 | Instead of modifying /etc/default/epoptes-client
| |
| 14:25 | <neyder_> my teacher machine is not server :)
| |
| 14:25 | <alkisg> Even if your server is not named server
| |
| 14:25 | It doesn't matter
| |
| 14:26 | <neyder_> like: "ip.ip.ip.ip server" in /etc/hosts ?
| |
| 14:26 | <alkisg> Yup
| |
| 14:26 | (or in your DNS server, if you're using one)
| |
| 14:26 | <neyder_> sure ill do it in the installation methods i'm doing (a personalized ubuntu for my school) ? but for now i'm just tryin,
| |
| 14:27 | * neyder_ sorry for the english | |
| 14:27 | <alkisg> No problem at all :) Is epoptes translated to your language?
| |
| 14:27 | <neyder_> yes!
| |
| 14:28 | <alkisg> Nice
| |
| 14:28 | <neyder_> it is, but i'll check on the way. if anything is wrong, and to work for another local languages (aymara and quechua)
| |
| 14:28 | alkisg: i'm working on this project http://escuelabpuno.org (in spanish sorry)
| |
| 14:28 | <alkisg> Cool, more info in http://www.epoptes.org/translations
| |
| 14:29 | Sugar desktop?
| |
| 14:29 | <neyder_> yup

| |
| 14:42 | <ogra_> well, last time i looked at it i wouldnt have used it in production, the code quality was rather uhmmm ...
| |
| 14:42 | but that might have improved... my last look was years ago
| |
| 14:42 | back then it was a big collection of hacks

| |
| 14:44 | i really wonder if its still alive

| |

| |
| 15:03 | <andygraybeal> alkisg, i wonder if you've had a chance to work on the script that ends users tasks on the fatclient from the server for me?
| |
| 15:03 | alkisg, it's no rush if you haven't, i'm just wondering.
| |
| 15:04 | <alkisg> andygraybeal: thanks for reminding me, no, I completely forgot about it after the initial implementation
| |
| 15:04 | <andygraybeal> alkisg, maybe you've forgotten too :) i'll have to remind myslf of the details as well!
| |
| 15:04 | ah thank you! :)
| |
| 15:05 | <alkisg> So, when user u1 logs in client c1, and he's already logged in client c2, you want that c2 processes forcibly terminated, right?
| |
| 15:05 | (even if that's really bad and should be prohibited etc etc?)

| |
| 15:13 | yes, that is correct. - but with a prohibitive prompt, letting him know he's on his own :P
| |
| 15:13 | i guess i can edit the prompts if it is regular text, myself.
| |
| 15:13 | i think the prompt that you hvae given me, works well.
| |
| 15:13 | *already given me
| |
| 15:14 | and i keep reminding them at our weekly meeting, so the people that it matters to understand the consequences.
| |
| 15:15 | <alkisg> The difficult part is that fat clients are involved, which cannot be easily informed about the server ssh process getting killed
| |
| 15:15 | I'll put it (again) in my todo list :)
| |
| 15:15 | But we're trying to solve some bugs in ltsp and epoptes these days, so it might take a while...

| |
| 15:17 | <andygraybeal> alkisg, for sure!
| |
| 15:17 | <alkisg> where when the ssh connection of a fat client login is killed,
| |
| 15:17 | <andygraybeal> the prob is it's confusing to explain :)
| |
| 15:17 | <alkisg> that user processes in the fat client die too
| |
| 15:17 | <andygraybeal> but yes, i will do my best.
| |
| 15:18 | rock on, you just explained it!
| |
| 15:18 | <alkisg> No need to involve autologins in the explanations
| |
| 15:18 | It would be a separate option
| |
| 15:18 | And you'd just combine the two options to get what you want

| 15:20 | <Hyperbyte> Doesn't LDM already have a limit one session configuration option?
| |
| 15:20 | <andygraybeal> Hyperbyte, yes, it does
| |
| 15:20 | <alkisg> It does, and it can kill processes of the same user in the ltsp server,
| |
| 15:20 | but of course that doesn't include processes running on other fat clients
| |
| 15:20 | <Hyperbyte> Ah, not on fat clients
| |
| 15:20 | Right. :)
| |
| 15:20 | <andygraybeal> yes, that'c correct Hyperbyte

| 15:21 | er, atleast close
| |
| 15:22 | <alkisg> Nah, that's roughly equivalent to bad ram
| |
| 15:22 | <andygraybeal> maybe that's like having an ltsp image loaded everyday and losing anythign recent.

| |
| 18:20 | Even if I change the size= parameters in lts.conf (tried 256, 512, and 1024)
| |
| 18:21 | <vagrantc> it's not lts.conf
| |
| 18:21 | <hydruid> oh lts.conf is not the proper place to setup the swap?

| |
| 18:37 | <hydruid> vagrantc, thank you, I think it's working because when i enabled it, the swap size does increase
| |
| 18:37 | it just doesn't get as big, according to top, as it is
| |
| 18:37 | <vagrantc> hydruid: top on the thin client? or on the server?
| |
| 18:37 | <hydruid> client
| |

| 18:53 | <alkisg> Hi vagrantc, hi all :)
| |
| 18:53 | <vagrantc> alkisg: i was surprised to find out yesterday that backporting to squeeze was trivial
| |
| 18:54 | <alkisg> Yey! It seems we're good coders :P :D
| |
| 18:54 | <vagrantc> in fact, it was a simple rebuild.
| |
| 18:55 | <alkisg> Is there something against chroot series-upgrading now?
| |
| 18:55 | E.g. can someone upgrade a squeeze chroot to wheezy?
| |
| 18:55 | <vagrantc> haven't tried, but in theory it should work.
| |
| 18:56 | i usually build a new chroot, just because it's makes it easier to revert if needed.
| |
| 18:57 | <alkisg> Yeah I also advice teachers here to reinstall newer OS versions in a second partition, so that they can revert to the old one by just selecting it in grub
| |
| 18:58 | Btw stgraber started filing bug reports for epoptes, we'll need a new release soon :D
| |
| 18:58 | <vagrantc> yes, gave me a heads up last night
| |
| 18:58 | <alkisg> One of them was about the certificate expire date, he says we would have less troubled users if we used an e.g. 40 years expiry date
| |
| 18:58 | <vagrantc> in theory, i'll have time friday
| |
| 18:59 | 5 years is too short?
| |
| 18:59 | <alkisg> 5 years is the time that LTS releases are supported
| |
| 18:59 | <vagrantc> people really should do some sort of security audit at least once every 5 years...
| |
| 18:59 | <alkisg> So if someone upgrades an LTS release...
| |
| 18:59 | The preinstalled snakeoil is valid for 10 years
| |
| 18:59 | <vagrantc> i'd rather see epoptes give a heads up when the certificate is getting close to expiring
| |
| 19:00 | <alkisg> But he prefers epoptes not using that
| |
| 19:00 | <vagrantc> right
| |
| 19:01 | <alkisg> So anyway now I'm not sure what I should do, put it for 5, 10, 20 or 40 years
| |
| 19:02 | For teachers here 40 would sound fine :P
| |
| 19:02 | Mava has left IRC (Mava!~Mava@ip-45-224.dhcp.opintanner.fi, Ping timeout: 246 seconds) | |
| 19:02 | <stgraber> vagrantc: the problem here is that the client side downloads the certificate, so we'd also need the client to check the expiry and warn the user somehow (hard when it's a background process)
| |
| 19:02 | srdjo has left IRC (srdjo!~srdjo@109.228.93.179, Quit: Leaving) | |
| 19:02 | <vagrantc> stgraber: sure...
| |
| 19:02 | <stgraber> vagrantc: so renewing the certificate means manual action on every client...
| |
| 19:03 | vagrantc: that's quite a bit worse than for example a web server where the client just prints a scary warning and easily lets the user load the new one
| |
| 19:04 | * vagrantc considers that even worse... | |
| 19:04 | <vagrantc> but that's a larger topic
| |
| 19:04 | <alkisg> In the far future, sure, epoptes-client could also pop up a dialog and use policykit for a user authentication to accept the certificate, but until then... :)
| |
| 19:04 | <vagrantc> 40 years seems absurdist.
| |
| 19:05 | <alkisg> Can we settle on 10, the default for snakeoil too?
| |
| 19:05 | I'm sure that epoptes won't be using the same certificate mechanism after 10 years :)
| |
| 19:05 | <vagrantc> i guess.
| |
| 19:07 | though auto-updating the cert shouldn't be needed, should it?
| |
| 19:07 | i.e. like the last one, which expired after a month?
| |
| 19:08 | <alkisg> I think that leaving the existing installations to 5 years is fine
| |
| 19:08 | <vagrantc> on package upgrades, it could warn the admin if the cert is going to expire "soon"
| |
| 19:08 | <alkisg> No need to force them sooner to transfer the certificate, if they have to do it in 5 years, let them do it then
| |
| 19:08 | <vagrantc> that would handle LTS -> LTS upgrades fairly reasonably.
| |
| 19:09 | <alkisg> I think that the epoptes package for the next LTS won't be using the same certificate mechanism :)
| |
| 19:09 | So it's a moot point anyway
| |
| 19:09 | <vagrantc> but if it is...
| |
| 19:09 | <alkisg> If it is, sure
| |
| 19:09 | <vagrantc> should use monkeysphere to verify the certs :)
| |
| 19:09 | http://web.monkeysphere.info
| |
| 19:10 | that provides an update mechanism that could be used.

| 21:06 | <epaphus> I know how LTSP works.. but is there any project out there that I can boot a vnc client... so that i can simply make X sessions on a thin client?
| |
| 21:06 | simplistic.
| |
| 21:07 | <Hyperbyte> epaphus, why would you want to use VNC rather than remote X?
| |
| 21:07 | <epaphus> Hyperbyte, whats the difference?
| |
| 21:14 | <vagrantc> epaphus: you could probably do what you want with LTSP
| |
| 21:14 | <Hyperbyte> Lots. Remote X uses tons of bandwith, but is very fast. VNC uses little bandwith, but is very slow.
| |
| 21:15 | <vagrantc> and there's also NX
| |
| 21:16 | <epaphus> ok how about Remote X? or VNC... is that possible? This way its extremely easy for the user to pick which X server to connect to... its a fast failover solution in case one isnt available or busy or under maintenance
| |
| 21:16 | <vagrantc> what's your goal? connect to a server on the local network?

| |
| 21:16 | vagrantc, yes
| |
| 21:17 | <vagrantc> epaphus: DHCP is one protocol that ltsp uses, not the only.
| |
| 21:17 | <epaphus> vagrantc, what other does it use? I just want to know what my options are :)
| |
| 21:17 | risca has left IRC (risca!~risca@wi-secure-3639.cc.umanitoba.ca, Ping timeout: 248 seconds) | |
| 21:17 | <vagrantc> epaphus: well, you can write hooks to use whatever protocols you want for information dissemination
| |
| 21:18 | LTSP is a collection of services to boot an operating system.
| |
| 21:18 | <epaphus> vagrantc, in ltsp?
| |
| 21:19 | <vagrantc> that operating system can be configured to do just about anything you could do with a disk'ed machine.
| |
| 21:19 | the default behavior is to connect to an LTSP server and run applications displayed locally.
| |
| 21:20 | epaphus: yes, LTSP has many places you can write hooks or plugins or configuration options.
| |
| 21:20 | risca has joined IRC (risca!~risca@wi-secure-3639.cc.umanitoba.ca) | |
| 21:21 | <epaphus> ok.. so on the other hand... what options do I have to simply let the user pick the vnc server.. or x server to connect to.
| |
| 21:23 | <vagrantc> i don't know that there's support for VNC out of the box, but it probably wouldn't be hard to write.
| |
| 21:23 | there are other similar protocol scripts for RDP
| |
| 21:23 | epaphus: why don't you just try it out and see what's there by default, and start tinkering with it?
| |
| 21:24 | epaphus: i don't feel like we have enough shared vocabulary to make meaningful recommendations.
| |
| 21:24 | <epaphus> ok. anybody else is welcome to suggest me then ... :)
| |
| 21:25 | <vagrantc> it just seems like you're stabbing in the dark without understanding what LTSP even is.
| |
| 21:28 | <epaphus> ok ill read more on ltsp... thank you vagrantc
| |
| 21:35 | <vagrantc> epaphus: if ii understand what you're saying, i think LTSP's default behavior would get 80-90% of what you're trying to do, but there are some corner cases that might be trickier.
| |
| 21:37 | <epaphus> vagrantc, ok. In this case any link you can provide me is appreciated.

| 21:43 | <naptastic> This isn't *quite* LTSP but is related. I'm setting up PXE / root over NFS on Debian, and some of my clients, some of the time, stop booting with "nfs: server 192.168.0.1 not responding, still trying"
| |
| 21:44 | Before that, there's a warning that "mount.nfs: remote share not in 'host:dir' format", but the clients that succeed at booting also show this warning.

| 21:44 | <IAssBurger> check your firewall
| |
| 21:44 | I had to iptables -F to get through to nfs even tho I had the ports open
| |
| 21:44 | iptables -F
| |
| 21:45 | <naptastic> IAssBurger, yeah, it's not the firewall. Some clients are able to boot, some of the time, and they're all on the same switch and interface.
| |
| 21:45 | <IAssBurger> k
| |
| 21:45 | <naptastic> I suspect that it's a race condition between something and something else, like the network not coming up fully before nfs tries to work its magic or something
| |
| 21:45 | but I have no idea how to troubleshoot or even diagnose that
| |
| 21:45 | I figured y'all would be the most likely crowd to know :-)
| |
| 21:46 | <IAssBurger> yeah I have a pxe client that wont boot to pxe at all, some Intel crap
| |
| 21:46 | <naptastic> mmm
| |
| 21:46 | <IAssBurger> Ive read that Intel PXE booting has its own caveats
| |
| 21:46 | <naptastic> this is all pro/100's on Transmeta Crusoe boards... it's weird.
| |
| 21:46 | <IAssBurger> yea my pro100 boots with no problem
| |
| 21:46 | <naptastic> hmm
| |
| 21:47 | the frustrating thing is that they *were* working
| |
| 21:47 | <IAssBurger> im a total noob in here, I just got fat clients booting
| |
| 21:47 | <naptastic> ah, ok
| |
| 21:47 | <IAssBurger> but I am using debian squeeze
| |
| 21:48 | and I assume I must share your frustration that the majority of the documentation or informationals online are geared toward ubuntu
| |
| 21:49 | in regards to ltsp, I mean
| |
| 21:49 | <naptastic> yeah... I don't really mind that part, though these things are ssh and serial interface only

| 21:49 | <IAssBurger> might be an issue with ssh
| |

| |
| 21:50 | <IAssBurger> did you tail -f /var/log/auth.log on the server abd watch whats going on with ssh in real time in regards to your issue
| |
| 21:50 | ssh might not be authenticating
| |
| 21:50 | its just a guess
| |
| 21:50 | but worth checking
| |
| 21:50 | <naptastic> well, I'm not trying to use ssh... it hasn't even had a chance to start on the client before their deaths

| |
| 21:50 | cant even load the pxelinux.0

| |
| 21:50 | <naptastic> they have to finish booting before I can try sshing in :-)

| 21:50 | oh no, they get past that
| |
| 21:51 | they get the kernel and initrd, set a bunch of stuff up
| |
| 21:51 | and then try to mount / over nfs and hang and die
| |
| 21:51 | <IAssBurger> so your ltsp server is also the dhcp server?
| |
| 21:51 | <naptastic> the funny thing is, I've done a tcpdump on the server, and they're actually not requesting anything
| |
| 21:51 | yeah, it's all one box
| |
| 21:51 | dhcp, tftp, nfs...
| |
| 21:51 | <IAssBurger> hey
| |
| 21:51 | I had a similar issue because network-manager was installed
| |
| 21:52 | it kept breaking the network connection
| |
| 21:52 | are these thick clients or thin
| |
| 21:52 | <naptastic> totally thin
| |
| 21:52 | there's physically no way to add hard drives :-)
| |
| 21:52 | <IAssBurger> I had to chroot and apt-get remove network-manager on my client images, but im using fat/thick clients so thats a totally diff issue
| |
| 21:52 | I have no hard disk in mine either
| |
| 21:52 | <naptastic> well... I wonder if it is
| |
| 21:53 | <IAssBurger> I like the power I get from using the local resourced on the client
| |
| 21:53 | <naptastic> I'm not even sure if it's installed.
| |
| 21:53 | <IAssBurger> doesnt bog out my server
| |
| 21:53 | <naptastic> yeah
| |
| 21:53 | well, that's the whole point of these. Distributed computing.
| |
| 21:53 | I was about to start on installing distcc, and then this problem started
| |
| 21:53 | <IAssBurger> what kind of terminals are you usin?
| |
| 21:54 | cpu, ram gpu etc?
| |
| 21:54 | <naptastic> Transmeta Crusoe's between 400 - 900mhz, 512MB RAM, 3 pro/100 nics, and a serial port.
| |
| 21:54 | That's IT.
| |
| 21:55 | <IAssBurger> yeah
| |
| 21:56 | wonder if there is a limitation on how many connections your nfs server can have
| |
| 21:56 | or if cpu load has anything to do with it
| |
| 21:57 | also are all the clients loading the same image?
| |
| 21:57 | ive no idea if that can be an issue or not, I would assume not
| |
| 21:59 | <naptastic> yeah, they're all using the same everything except for one client, which is different hardware, so it's got some different pxe options
| |
| 21:59 | it has the same problem, just more reliably.

| 22:04 | artista_frustrad has left IRC (artista_frustrad!~fernando@200.247.43.2, Quit: Leaving) | |
| 22:05 | <IAssBurger> have you been monitoring the cpu loads on your server?
| |
| 22:05 | <Hyperbyte> naptastic, sounds like something wrong with /etc/exports on the server. Wild guess here, before nap time. :-)
| |
| 22:05 | G'night.
| |
| 22:05 | <IAssBurger> ahhh could be
| |
| 22:05 | whats your /etc/exports look like?
| |
| 22:06 | I just use
| |
| 22:06 | /opt/ltsp/ *(ro,no_root_squash,async,no_subtree_check,fsid=0)

| 22:11 | <naptastic> IAssBurger, yeah, mine's exactly the same except it's /srv/nfs but yeah
| |
| 22:11 | <IAssBurger> hey can u tail -f /var/log/syslog
| |
| 22:11 | you even tail your logs like that?
| |
| 22:11 | basically shows them in real time
| |
| 22:11 | might be something relevant in your syslog
| |
| 22:13 | mount.nfs: remote share not in 'host:dir
| |
| 22:13 | hmm in your dhcp.conf do you have root dir speficied?
| |
| 22:13 | <naptastic> IAssBurger, okay, so after many failed attempts
| |
| 22:13 | (yeah, and I've tried with and without the ip address)
| |
| 22:13 | I've determined that the "remote share not in 'host:dir' format" is NOT part of the problem
| |
| 22:14 | that warning appears on clients that succeed and fail, both
| |
| 22:14 | <IAssBurger> option root-path "/opt/ltsp/i386";
| |
| 22:14 | <naptastic> yep, that's definted
| |
| 22:14 | <IAssBurger> I also have this entry below mine
| |
| 22:14 | if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
| |
| 22:14 | filename "pxelinux.0";
| |
| 22:14 | } else {
| |
| 22:14 | filename "nbi.img";
| |
| 22:14 | <naptastic> oh yeah, ok
| |
| 22:14 | <IAssBurger> read that in a ubuntu tut
| |
| 22:15 | no idea if its doing me any good
| |
| 22:15 | lol
| |
| 22:15 | <naptastic> you can do the same thing using MAC-specific pxelinux.cfg files
| |
| 22:15 | (which is how I'm discriminating between my RXL cards and my Dell workstation)
| |
| 22:16 | <IAssBurger> NFS Server Is Not Responding
| |
| 22:16 | If your clients exhibit an error, similar to nfs warning: server not responding, it is possible that the kernel is using too large a block size for the NFS packets
| |
| 22:16 | <alkisg> naptastic: I've seen 2 problems with nfs, not sure if any of those helps. In the first one, I needed to use "nolock" on the clients because statd sometimes wasn't starting due to race conditions. On the other, I had to change the window size on atheros nics, otherwise they had problems (i.e. hanged) specifically with nfs.
| |
| 22:16 | Both in Ubuntu
| |
| 22:16 | <IAssBurger> In essence the kernel uses a 32K block size, which must be broken down into 1,500 byte datagrams. Since this results in a large number of small datagrams being sent, the client can time out before receiving all the data. Fortunately, the fix is simple enough.
| |
| 22:17 | You must load the file /var/lib/tftpboot/ltsp/pxelinux.cfg/default so that it can be edited. To do this you can use any of the methods previously described in this chapter. Once the file is open, there is a line beginning with APPEND; to the end of this line, you must add one of the following:
| |
| 22:17 | <naptastic> alkisg, that sounds likely--since some clients work and some clients don't, a race condition seems most likely
| |
| 22:17 | <alkisg> naptastic: you're using nfsroot=xxx, so that initramfs is mounting root?
| |
| 22:17 | <naptastic> alkisg, yeah. Does nolock go on the append line too?
| |
| 22:17 | <IAssBurger> NFSOPTS="-o nolock,ro,wsize=2048,rsize=2048"
| |
| 22:18 | its here
| |

| |
| 22:18 | <alkisg> http://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt
| |
| 22:18 | nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>]
| |
| 22:19 | naptastic: also, since you said they had 3 nics, did you take measures to have the correct one used for the nfs mounting?
| |
| 22:19 | * naptastic reads, parses, groks... | |
| 22:19 | <alkisg> E.g. ipappend 2?
| |
| 22:20 | <naptastic> alkisg, yeah, they're on the right nic. That's one nice thing about these: they're set up so ethx *ALWAYS* stays the same
| |
| 22:20 | I actually had to turn the persistent device names off to get it working right
| |
| 22:21 | <alkisg> IPAPPEND 2 passes BOOTIF in the kernel command line so that you don't have to care about that
| |
| 22:22 | <naptastic> The parameter in mine is ip=:::::eth2:
| |
| 22:22 | which I find hilarious
| |
| 22:23 | "Use eth2, you're on your own for the rest!!!"
| |
| 22:23 | <alkisg> Yes, it is, BOOTIF uses mac address and it's much better
| |
| 22:23 | <naptastic> oh yeah but then I'd need a file for every client, and in the near future there will be hundreds
| |
| 22:23 | no quiero
| |
| 22:23 | <alkisg> You just put IPAPPEND 2 at the end of pxelinux.cfg/default
| |
| 22:23 | The BOOTIF is passed by pxelinux.0 itself, not by your configuration files
| |
| 22:24 | So you don't need to know the clients mac addresses
| |
| 22:25 | <naptastic> ...interesting...
| |
| 22:25 | it's this whole freaking world of options... who can understand it all?????
| |
| 22:25 | <IAssBurger> I have an issue gentlement, the time is correct on my server, it is correct in the bios on my client, but when my fat client boots, the time is HOURS off, and if I try to set the time on the client the box freezed
| |
| 22:26 | <alkisg> Anyway, it's later here, 'night all

| 22:35 | <IAssBurger> hey guys
| |
| 22:36 | one thing I noticed . when using thin client, from 1 server to 1 machine I would see upwards of 100mbps traffic when just browsing
| |
| 22:36 | but fat client uses nowhere near that much bandwidth
| |
| 22:36 | running snmp with dude network monitor i can see it
| |
| 22:37 | as well as iptraf from command line on the server
| |
| 22:40 | <naptastic> ...I think I need a drink... <--lol
| |
| 22:46 | NFSOPTS="-o nolock,ro,proto=tcp"
| |
| 22:53 | <naptastic> IAssBurger, that's because the thin client has to transfer all the pictures of the browser window, where the fat client just needs the actual web data
| |
| 22:54 | <IAssBurger> yeah I couldnt imagine the demands of a production environment with multiple active thin clients
| |
| 22:54 | would be absurd even on gb
| |
| 22:54 | no wonder your having race conditions
| |
| 22:54 | thats not even considering cpu usage on the server
| |
| 23:03 | <naptastic> heh
| |
| 23:03 | these are non-graphical, which makes things a lot easier
| |
| 23:03 | but when we get them crunching numbers, we will run into the limits
| |
| 23:03 | anyway, I'm pretty sure at this point that something is really wrong with this server.
| |
| 23:04 | I started suspecting the NIC, so I traded it places with another, re-assigned things, and now none of the networking is, well, working.
| |
| 23:05 | <IAssBurger> your os will see it as a diff network card
| |
| 23:05 | if your old adapter was eth0
| |
| 23:05 | it will likely see it as eth1
| |
| 23:05 | so edit /etc/network/interfaces
| |
| 23:05 | and change the eth0 lines to eth1 or whatever it happens to now be
| |
| 23:05 | then reboot
| |
| 23:06 | but dont forget to also change it in your dhcp server
| |
| 23:06 | ifconfig and see what it is now
| |
| 23:06 | should be pretty straight forward
| |
| 23:07 | wouldnt hurd to reboot your switches too when you do that, sine your ip will have a new mac adress associated with it, so you avoid any stale arp
| |
| 23:09 | <naptastic> IAssBurger, yeah, I updated that. You can also change the device names that are being forced by editing /etc/udev/rules.d/70-persistent-net-rules.conf (or equivalent)
| |
| 23:09 | ...which apparently I screwed up somehow on this server, because it's empty and my interfaces are getting shuffled...
| |
| 23:10 | ...maybe it will regenerate it if I reboot enough times...
| |
| 23:12 | <IAssBurger> hey, if your devices on your lan are still associating your old nics mac with that ip, packets wont be able to make it to your server
| |
| 23:12 | reboot your stuff, all of it, if you change the nic
