| 06:31 | <Barco> Morning, how do I get a LTSP client to boot from the server's Eth1?
| |
| 06:32 | <vagrantc> !seen alkisg
| |
| 06:32 | <ltsp> vagrantc: alkisg was last seen in #ltsp 8 hours, 23 minutes, and 15 seconds ago: <alkisg> Anyway, time to go. bb all.
| |
| 06:37 | <vagrantc> Barco: so you have eth0 connected to the rest of the network/internet, and eth1 connected to it's own network?

| 06:45 | <Hyperbyte> Morning. :_
| |
| 06:45 | ** :)
| |
| 06:51 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 06:54 | <alkisg> Good morning
| |
| 06:58 | * vagrantc waves | |
| 07:00 | Parker955 is now known as Parker955_Away | |
| 07:13 | Parker955_Away is now known as Parker955 | |
| 07:17 | Parker955 is now known as Parker955_Away | |
| 07:20 | Parker955_Away is now known as Parker955 | |
| 07:25 | <Barco> No, I have both nic's available on Lan and use 3G for internet. But Eth1 is a Gigabit connection and Eth0 is 100mb
| |
| 07:27 | Would be nice if I could serve client requests from both Eth1 and Eth0 for traffic sake
| |
| 07:27 | <alkisg> Are your switch/clients gigabit?
| |
| 07:29 | <Barco> Switch is Gigabit, clients are 100mb
| |
| 07:29 | <alkisg> Make sure you don't have the flow control problem: https://help.ubuntu.com/community/UbuntuLTSP/FlowControl
| |
| 07:29 | If you don't have it, then only use the gigabit connection, it's not worth it to bond the other one
| |
| 07:30 | To make sure the clients boot from the gigabit nic, just set your IPs and dhcpd.conf to match
| |
| 07:30 | How many clients?
| |
| 07:32 | <Barco> I have 10clients. But even If just 4 run the whole thing lags. How do I do set Ip's and to match dhcpd.conf?
| |
| 07:32 | Running 2 unmanaged Dlink 8port Gigabit Switches. Dgs1008D
| |
| 07:33 | <alkisg> Barco: it's very probable that you're hitting the flow control problem. Which nic do you have on the server?
| |
| 07:33 | lspci -nn -k | grep -A 2 Ethernet
| |
| 07:33 | and:sudo ethtool --show-pause eth0
| |
| 07:33 | With the flow control problem, your whole network functions as 100 mbps instead of gigabit
| |
| 07:34 | That would explain the lag
| |
| 07:34 | For 10 clients, you should be able to have them all watch a divx video full screen, with no lost frames
| |
| 07:34 | <vagrantc> or the bottleneck might not be network...
| |
| 07:34 | <Barco> Realtek Rtl8111/8168B - see the onboard is gigabit too, that makes flow control probable
| |
| 07:35 | <alkisg> Not probable, certain
| |
| 07:35 | <muppis> I wonder what would happen if there is bonded 2 x 10 Gbps in server and 1 Gbps in clients.
| |
| 07:35 | <alkisg> Barco: the best solution for you is to go and buy an intel card for your server
| |
| 07:35 | Or better yet, 2 of them, because you have 2 cheap switches
| |
| 07:35 | <Barco> Running 4gb ram with a 3Gb Core2duo processor
| |
| 07:36 | <alkisg> So even if your server <=> 1st switch won't have the problem, the swich<=> switch connection will
| |
| 07:36 | So my advice is, buy 2 intel gigabit nics, you'll see more than 10 times better network bandwidth
| |
| 07:36 | * alkisg unfortunately has had this problem in dozens of labs so far :-/ | |
| 07:37 | <Barco> As in Intel 1Gb net connected to the one switch and the other to the other switch?
| |
| 07:37 | <alkisg> Yes
| |
| 07:38 | <Barco> aha, how would I setup availability of both network cards for tftp boot?
| |
| 07:38 | <alkisg> You'd just use different subnets, e.g. 192.168.0.x and 192.168.1.x
| |
| 07:38 | tftpd would work automatically, and you'd need to define ranges for dhcpd
| |
| 07:39 | <Barco> That's great in theory and I'll do that in a snap for Windows but I'm not so clued up on all the deeper details on Ubuntu yet
| |
| 07:39 | <alkisg> You can set it up now, with your existing cards
| |
| 07:40 | But you'll only have 200 mbps bandwidth instead of 2 gigabit
| |
| 07:40 | So it'll be much much slower, yet a little faster than what you have now, which is 100 mbps
| |
| 07:40 | <Hyperbyte> I can't believe how many people buy good computers for LTSP and then try to save a few bucks on network
| |
| 07:41 | I mean, a Realtek onboard network card, are you serious? I wouldn't trust these things to route network traffic even if my job didn't depend on it...
| |
| 07:41 | <alkisg> Realteks work fine on full gigabit networks
| |
| 07:41 | It's the gigabit/100mbps mix that causes the problem,
| |
| 07:41 | <Hyperbyte> Realteks are aweful. They don't achieve full gigabit potential and they get way too hot and die way too easily.
| |
| 07:41 | <alkisg> and it's due to those silly switches that supposedly offer "flow control", while their implementation is broken
| |
| 07:42 | <Barco> LOL, I was kinda on a budget, the second one is also realtek chipset. So I started with what I have took it from there.
| |
| 07:42 | <alkisg> Barco, with at least one, or better yet with two, intel gigabit nics you'll be pretty much ok
| |
| 07:43 | <Barco> Agreed, how much does a decent intel gig nic cost?
| |
| 07:43 | <alkisg> Here, 25€
| |
| 07:43 | (greece)
| |
| 07:44 | <Barco> Not too bad! About what the switches cost ;)
| |
| 07:44 | <alkisg> The best solution would be to buy a descent 16 port switch
| |
| 07:44 | E.g. a linksys or hp one
| |
| 07:44 | <Hyperbyte> Barco, what kind of cabling do you use?
| |
| 07:45 | <alkisg> Those don't have the flow control problem, so it's solved automatically, and you'll get better performance if you ever upgrade the clients to gigabit
| |
| 07:45 | The downside is that they cost > 200€ here :-/
| |
| 07:45 | That's why we settle with intel nics instead, too...
| |
| 07:45 | <Barco> I use cat6 between the switches and server. and Cat5.e to clients
| |
| 07:46 | Seems like a good low cost solution to get better nic's instead of fork out 200 euro for a Switch
| |
| 07:47 | <alkisg> A thing to keep in mind, is that the pci bus only goes up to a gigabit in speed
| |
| 07:47 | So for 2 nics, it's better to use pci-e
| |
| 07:48 | <Barco> I could make the whole thing gigabit later, But was figuring that providing 100mb connection on 10 pc's is like QOS without expensive hardware
| |
| 07:48 | <alkisg> A dvd needs 125 mbps for playback
| |
| 07:48 | So with 100mbps connection you get a few dropped frames
| |
| 07:48 | <Barco> I'll keep that in mind when I purchase. I want to run flash video content
| |
| 07:48 | <alkisg> Otherwise yeah it works like a qos
| |
| 07:49 | Flash video is much worse, it doesn't use xv
| |
| 07:49 | And it wastes a *lot* of server/client cpu
| |
| 07:49 | <Barco> Ugh,
| |
| 07:49 | <alkisg> So you might hit other bottlenecks there
| |
| 07:49 | For non-full-screen youtube you'll be ok, for full screen... not so much
| |
| 07:49 | <Barco> I'm running Flash and Firefox as local apps
| |
| 07:49 | <alkisg> Ah, different story there, you don't need good network for that
| |
| 07:50 | Just good client cpu
| |
| 07:50 | Parker955 is now known as Parker955_Away | |
| 07:50 | <Barco> Not doing flv, Using SWF for Training. So it's basicly Presentation with sound.
| |
| 07:51 | Runs with dropped frames on 3-4 clients. Entire file around 6mb
| |
| 07:52 | So it seems to still have a perfomance issue. Clients run Older Celeron 465 Cpu's 2ghz and above
| |
| 07:53 | <alkisg> Wait, I didn't understand, does that run locally or not?
| |
| 07:55 | For content that runs on the server: you currently have 100 mbps network. In the future you'll have gigabit. So, however well it runs on ONE client now, it'll run on 10 clients in the future. Of course that's true only if you don't hit bottlenecks other than the network.
| |
| 07:55 | <Barco> Well... difficult to say. I've setup Firefox and Flash as local apps as described in LTSP docs But the content still comes from a webserver over the network...
| |
| 07:55 | <alkisg> If firefox is local, then flash is local, it shouldn't be affected by your slow 100mbps network
| |
| 07:55 | <Barco> How stable is 64bit ltsp server?
| |
| 07:55 | <alkisg> Run ps -ef on the server to verify
| |
| 07:56 | If you don't see a firefox process, you're ok
| |
| 07:57 | <Barco> Seems I'm ok :)
| |
| 07:58 | What could be causing the slowdown then? Cause navigating content is slow motion when more clients run.
| |
| 07:59 | <alkisg> Content that runs locally should run as fast as if the client was booted with a live cd/usb stick
| |
| 07:59 | So to verify that nothing is wrong with your ltsp installation, try with a live stick
| |
| 07:59 | <Barco> BTW what do you use LTSP for - Own lab or manage labs?
| |
| 08:00 | <alkisg> Me? I have my own school lab, but I also help about 250 more schools here with their installations
| |
| 08:00 | <Barco> Ok, Will try that and see. But as I understand the content would still technicly come from server over network as the clients are diskless?
| |
| 08:00 | <alkisg> As it usually does with e.g. youtube
| |
| 08:01 | I.e. the content is already compressed, and it's streamed, so it shouldn't need much bandwidth
| |
| 08:01 | E.g. < 1 mbps for each client
| |
| 08:01 | <Barco> Cool, I want to start doing that when I am up. There are many rural schools here in my town in South Africa
| |
| 08:02 | <alkisg> The client cpu might also be a problem with fullscreen flash apps
| |
| 08:02 | Run top while watching the presentation, to verify
| |
| 08:02 | <Barco> If it's still slow after this I guess I would need to not run Firefox as a local app an make my server do the work?
| |
| 08:02 | Top?
| |
| 08:03 | <Hyperbyte> Type 'top' in a terminal :)

| 08:03 | <alkisg> !localxterm
| |
| 08:03 | <ltsp> alkisg: localxterm: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client..
| |
| 08:05 | <Barco> I see. I have much to learn yet. I kinda jumped in the deep end and started swimming for dear life
| |
| 08:05 | So top is a system monitor on command line...
| |
| 08:07 | <Hyperbyte> Barco, basically. Server management in Linux is designed to be done from the command line. You'll find the command line is very powerful and has lots of tools available. :)
| |
| 08:08 | (one of the things I've always loved about it :))
| |
| 08:08 | <Barco> I noticed the lack of GUI management. Used some Commandline but have yet to read the manual. Therein lies the problem :)
| |
| 08:10 | I love commandline when you get used to the commands. It's more efficient. But in Linux I'm still a bit lost appart from installing apps, navigating dir and editing files.
| |
| 08:11 | alkisg - CPU load seems low peaks at 30% with 40% mem free. Seems to be slow network. Using one client is fine
| |
| 08:11 | <Hyperbyte> Barco, well, the command 'man' will be useful to you. It calls manual pages for other commands. Try 'man top', for example. :)
| |
| 08:11 | <alkisg> Barco: if one client is fine, and 4 clients are not fine, then you're not using localapps?!
| |
| 08:11 | Something's wrong there, have another look at what you're doing
| |
| 08:12 | Localapps should be mostly unaffected by the local network speed, and by how many clients run the same localapp in parallel
| |
| 08:13 | Localapps shouldn't show up in the server `top`, and they shouldn't affect the server CPU usage
| |
| 08:16 | <Barco> It's on the client that I pulled stats with top.
| |
| 08:17 | <alkisg> Yes, but what you're reporting doesn't explain why the app doesn't run OK for 4 clients, if it runs OK for 1 client.
| |
| 08:18 | <Barco> Question, after loading Firefox into the i386 boot image as local app...
| |
| 08:18 | and adding localapps=yes ... and menu items to Config file, should I open Firefox using ltsp-localapps Firefox from terminal?
| |
| 08:19 | Or can I open it from the GUI?
| |
| 08:20 | <alkisg> LOCAL_APPS is true by default, you don't need that. But you do need to set LOCAL_APPS_MENU=True in lts.conf
| |
| 08:20 | After you do that, you can run firefox from the menu, and it'll run locally.
| |
| 08:20 | <Barco> one moment, I'll pull what I have in lts.conf
| |
| 08:20 | <alkisg> To verify that it runs locally: (1) `ps -ef | grep firefox` on the localxterm should show it, and `ps -ef | grep firefox` on the server should not show it.
| |
| 08:21 | <Barco> Umh, Still running on server....
| |
| 08:22 | [default] LDM_THEME=edubuntu LDM_XSESSION="gnome-session -- session=classic-gnome" VOLUME=90 PCM_VOLUME=90 LOCAL_APPS=TRUE LDM_DIRECTX=TRUE NETWORK_COMPRESSION=TRUE LOCAL_APPS_MENU = True LOCAL_APPS_MENU_ITEMS = firefox
| |
| 08:22 | <alkisg> On the local xterm, run: getltscfg -a
| |
| 08:22 | And put the output to pastebin
| |
| 08:22 | !pastebin
| |
| 08:22 | <ltsp> alkisg: pastebin: the LTSP pastebin is at http://ltsp.pastebin.com. Please paste all text longer than a line or two to the pastebin, as it helps to reduce traffic in the channel. Don't forget to paste the URL of the text here..

| 08:30 | <Barco> ltsp-client core not installed... Should I install to Client Image?
| |
| 08:32 | <Hyperbyte> Barco, you are not executing the command on the client I bet.
| |
| 08:32 | ltsp-client is already in the image, else it would never work.
| |
| 08:32 | Did you run getltscfg in a local xterm?
| |
| 08:32 | <alkisg> !localxterm
| |
| 08:32 | <ltsp> alkisg: localxterm: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client..

| |
| 08:44 | <alkisg> Barco: your lts.conf seems ok

| 08:51 | <Barco> Local processes on the server show Lab002 running Firefox - shouldn't show up right? http://pastebin.com/Hf7UbwRE -
| |
| 08:51 | <alkisg> Barco: if you mark things on an xterm, you can paste them somewhere else with the middle mouse click
| |
| 08:52 | <Barco> That's fine but once I enable Inet on the terminal the servers Inet connection goes down.
| |
| 08:52 | <alkisg> Barco: right, so, your problem for slow performance so far is "my localapps firefox is not working, it's running on the server instead"
| |
| 08:52 | leio has joined IRC (leio!~leio@gentoo/developer/leio) | |
| 08:52 | <alkisg> If you open firefox on a thin client, you get disconnected?!!
| |
| 08:53 | <Barco> Also I havn't quite figured out how to access my server File system from a client...
| |
| 08:53 | <Hyperbyte> There's no LOCAL_APPS_MENU=True in your lts.conf
| |
| 08:53 | Shouldn't there be?
| |
| 08:53 | <Barco> No If I enable the second network card I have internet on the clients but not the server
| |
| 08:53 | * Hyperbyte reads manpage | |
| 08:53 | <Hyperbyte> Yes there should.
| |
| 08:56 | Barco, stick with one problem at a time. Right now we're trying to get Firefox running as a local app on the thin client, after that we'll get to the rest.
| |
| 08:56 | :)
| |
| 08:56 | <Barco> Ok let me try to paste ISO type... One moment
| |
| 08:57 | <Hyperbyte> Did you see what I wrote?
| |
| 08:57 | 10:53 <Hyperbyte> There's no LOCAL_APPS_MENU=True in your lts.conf
| |
| 08:57 | There should be. So add that to lts.conf
| |
| 08:57 | <alkisg> Hyperbyte: I'm guessing that's a typo too, a little before he had pasted LOCAL_APPS_MENU = True
| |
| 08:57 | Barco: sit on a client, open a gnome terminal
| |
| 08:57 | <Barco> Here's the actua paste http://pastebin.com/YS2Uwqse
| |
| 08:57 | <alkisg> Run: ltsp-localapps xterm to get a localxterm
| |
| 08:58 | And run: firefox to get a firefox running on the server, so that you can paste stuff
| |
| 08:58 | OK, it seems that you managed it :)
| |
| 08:58 | <Hyperbyte> Yeah, that looks better. :)
| |
| 08:58 | <Barco> Sneakernet ;)
| |
| 08:58 | What would we do without flash drives
| |
| 08:59 | <alkisg> Barco: now, from the localxterm, run firefox
| |
| 08:59 | That will run firefox locally
| |
| 08:59 | Can you access the internet with that firefox?
| |
| 08:59 | <Barco> Yes if I enable eth1 but then the server Internet becomes inacessable for some reason
| |
| 09:00 | <alkisg> Don't enable eth1
| |
| 09:01 | Did the local firefox open?
| |
| 09:01 | <Barco> Correction - I have internet on client without Eth1
| |
| 09:01 | Firefox has opened fine...
| |
| 09:02 | <alkisg> Barco: ok, then you can copy stuff from the localxterm, and paste them to pastebin from that firefox
| |
| 09:02 | So, run this command on the localxterm, and paste the output to pastebin: ps -ef
| |
| 09:02 | You can see all the output with shift + page up
| |
| 09:03 | In other words, "show us the process list from your client, while firefox is supposed to be running locally there"
| |
| 09:05 | <Barco> http://pastebin.com/Yk1QYZmF
| |
| 09:06 | <alkisg> http://pastebin.com/Vk1QYZmF is the correct one
| |
| 09:06 | Barco: do you see that firefox is *not* there?
| |
| 09:06 | So, you didn't run it from the localxterm
| |
| 09:07 | Close firefox completely
| |
| 09:07 | <Barco> Ok,
| |
| 09:07 | <alkisg> Then, go to the localxterm, and type: firefox
| |
| 09:08 | So to sum up, so far you've been unable to run firefox locally, and that's why it runs OK for 1 client but not for 4 clients, because it runs on the server.
| |
| 09:08 | <Barco> When I type firefox in localxterm I get "command not found"
| |
| 09:08 | <alkisg> So, firefox isn't installed in your chroot
| |
| 09:09 | Ghidorah has left IRC (Ghidorah!4a7e0f79@gateway/web/freenode/ip.74.126.15.121, Ping timeout: 252 seconds) | |
| 09:09 | <alkisg> Let's move to your server now. Are you seated physically on your server? Or do you have access through ssh etc?
| |
| 09:10 | <Barco> I am seated at the server
| |
| 09:10 | <alkisg> OK. What's the output of this command? sudo chroot /opt/ltsp/i386 dpkg -l firefox
| |
| 09:11 | <Barco> http://pastebin.com/iWZMYUHU
| |
| 09:12 | <alkisg> OK, and the output of this command? sudo mount -o loop /opt/ltsp/images/i386.img /mnt && sudo chroot /mnt dpkg -l firefox && sudo umount /mnt
| |
| 09:13 | <Barco> No packages found matching firefox.
| |
| 09:13 | <alkisg> So the problem is that you installed firefox in the chroot, but you didn't run ltsp-update-image
| |
| 09:13 | So, run: sudo ltsp-update-image
| |
| 09:14 | And then reboot your client
| |
| 09:15 | <Barco> Thanks, I must have forgotten. I was a bit rushed when installing...
| |
| 09:16 | One moment...
| |
| 09:21 | Ok it's running, I have Firefox open through local Xterm on the client. It's not connecting to the web or localhost anymore
| |
| 09:23 | Where do I set the DNS and GATEWAY for the local Browser?
| |
| 09:24 | <alkisg> Now you need to do NATting on your server for the clients to access the internet: https://help.ubuntu.com/community/UbuntuLTSP/ThinClientHowtoNAT
| |
| 09:24 | leio has left IRC (leio!~leio@gentoo/developer/leio, Remote host closed the connection) | |
| 09:25 | <alkisg> Barco: start from step "4" there, the previous shouldn't be needed
| |
| 09:26 | And instead of step "6", just use the DNS_SERVER directive of lts.conf
| |
| 09:26 | leio has joined IRC (leio!~leio@gentoo/developer/leio) | |
| 09:26 | <alkisg> (meh that natting page needs to be rewritten from scratch)
| |
| 09:31 | <Barco> cant find /etc/network/interfaces to add the line http://pastebin.com/Wtu0Vcpx
| |
| 09:31 | last ran sudo sh -c 'iptables-save > /etc/ltsp/nat'
| |
| 09:32 | <alkisg> How did you set the ip for your server? From network-manager?
| |
| 09:32 | cyberorg has left IRC (cyberorg!~cyberorg@opensuse/member/Cyberorg, Read error: Connection reset by peer) | |
| 09:32 | <Barco> Used default provided by edubuntu.
| |
| 09:32 | <alkisg> Ah so you don't have a static ip?
| |
| 09:33 | Run these 2 commands on your server:cat /etc/network/interfaces; sudo ls /etc/NetworkManager/system-connections/
| |
| 09:33 | <Barco> No, not yet. Thought it would be a good thing for future
| |
| 09:34 | <alkisg> You need a static IP for ltsp to work properly, otherwise whenever it changes the ssh keys change and the clients are unable to login until you update the keys + image
| |
| 09:35 | <Barco> http://pastebin.com/iNqe1M2b here's what I have on the first cmd Server IP is 192.168.0.254
| |
| 09:35 | <alkisg> OK, so, what you need to do is (1) use a static ip for your server and (2) do NATting.
| |
| 09:35 | /me needs to do some work, I hope some other will be able to follow up and help you
| |
| 09:35 | Right that's the interfaces file
| |
| 09:35 | Why did you say you couldn't find it?
| |
| 09:36 | * alkisg bbl | |
| 09:36 | <Barco> Tried looking for it as a location as opposed to running it from term
| |
| 09:36 | Thank you so much for your help!
| |
| 09:36 | Enjoy Work...

| |
| 12:14 | <Ghidorah> Lunching firefox I get a failed to contact configuration server
| |
| 12:14 | common cause is misconfigured D-Bus
| |

| 12:15 | <Hyperbyte> Ghidorah, check that home directory is mounted and writable on the client
| |
| 12:15 | <alkisg> sudo chroot /opt/ltsp/i386 dpkg -l '*firefox*' | grep ^ii
| |
| 12:16 | (or amd64)
| |
| 12:17 | <Ghidorah> alkisg: firefox 5.0+build1+nobinonly-0ubuntu0.11.04.2
| |
| 12:17 | <alkisg> Do the same on your server, and install the missing packages for gnome support
| |
| 12:17 | firefox-gnome-support
| |
| 12:18 | <Ghidorah> Hyperbyte: it appears that it is /home mounted and writable
| |
| 12:21 | :-/ firefox-gnome-support is installed on both the chroot and app server
| |
| 12:21 | it is not install on the ltsp-cluster root server because I don't have X on it.
| |
| 12:23 | <alkisg> Hmmm do paste the actual lines because pasting only half of them is confusing
| |
| 12:24 | So let's start over: paste the exact error when you start firefox
| |
| 12:24 | <Ghidorah> I'm sorry about that
| |
| 12:24 | hang on
| |
| 12:28 | GConf Error: Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. (Details - 1: Failed to get connection to session: Error or spawning command line 'dbus-launch --autolaunch=ae7be12d89f6bd292fbb4fc00000004 --binary-syntax --close-stderr': Failed to execute child process "dbus-lunch" (No such file or directory))
| |
| 12:33 | <alkisg> dbus-lunch?
| |
| 12:33 | Or dbus-launch?
| |
| 12:34 | Because if it's dbus-lunch, then it's mispelled, probably a firefox bug. Try symlinking dbus-lunch to dbus-launch until the bug is fixed.
| |
| 12:35 | <Ghidorah> launch, sorry I had to type it out... couldn't figure out how to extract that message from local-apps xterm
| |
| 12:35 | <alkisg> Ah. Select + middle click
| |
| 12:35 | <Ghidorah> dang.
| |
| 12:35 | <alkisg> In a localxterm, if you run `which dbus-launch`, is it there?
| |
| 12:36 | <Ghidorah> No.
| |
| 12:36 | <alkisg> That's the problem then, missing dbus-x11 package
| |
| 12:37 | <Ghidorah> alkisg: which state do you live in?
| |
| 12:37 | <Hyperbyte> Heh
| |
| 12:37 | <Ghidorah> or country...
| |
| 12:37 | <alkisg> I don't know why firefox wants to contact dbus though, and if installing it will actually help in anything
| |
| 12:37 | State... Epirus :P
| |
| 12:37 | Greece
| |
| 12:38 | <Ghidorah> dang... Its hard to buy you a beer from here then.
| |
| 12:38 | <alkisg> Hehe
| |
| 12:38 | I think I saw e-pizza and e-beer services somewhere in the net
| |
| 12:38 | <Ghidorah> I do truely appreciate your patience and help
| |

| |
| 12:46 | Not as a local app though.
| |
| 12:46 | <Ghidorah> :(
| |
| 12:46 | <Hyperbyte> But it works as a local app too (I tested)
| |
| 12:47 | <Ghidorah> It works as a localapps
| |
| 12:47 | just having a heck of a time getting flash to work in it
| |
| 12:47 | I know local app flash works... chromium + flash in local app works without issue.
| |
| 12:49 | <Hyperbyte> But ehm... when did you flash get in here?
| |
| 12:49 | Because you were having issues with running Firefox as a local app I believe.
| |
| 12:49 | dbus related issues.
| |
| 12:50 | <Ghidorah> I couldn't confirm it was a dbus related issue. It was the only error that I had to work with so far.
| |
| 12:50 | I was praying it was a dbus issue :-/
| |
| 12:54 | <Hyperbyte> But Firefox doesn't start all?
| |
| 12:54 | *at all
| |
| 12:54 | You need to explain a bit better... what happens and when do you get the error?
| |
| 12:55 | <Ghidorah> Firefox runs without issue.
| |
| 12:55 | Flashplugin crashes
| |
| 12:55 | Firefox stays open
| |
| 12:56 | <Hyperbyte> And at what point do you get the GConf/dbus error?
| |
| 12:56 | <Ghidorah> When I launched firefox from xterm it presented the dbus error, firefox continued to function
| |
| 12:56 | <Hyperbyte> Okay, so disregard that
| |
| 12:57 | <Ghidorah> My hope was that firefox was calling dbus because of flash
| |
| 12:57 | <Hyperbyte> The point where the flashplugin crashes, and what Firefox prints to the console then, that would be interesting
| |
| 12:57 | <Ghidorah> That is what I'm trying to figure out how to get
| |
| 12:57 | When the plugin crashes I get no output in the terminal
| |
| 12:57 | <Hyperbyte> Okay
| |
| 12:57 | Go to about:plugins in Firefox
| |
| 12:58 | <Ghidorah> k
| |
| 12:58 | there.
| |
| 12:58 | <Hyperbyte> One moment
| |
| 12:58 | Need to call it as well to remember what the page looks like
| |
| 13:00 | There's a header there from the flash plugin
| |
| 13:00 | And below it says file is libflashplayer.so
| |
| 13:00 | Pastebin that whole section, or make a screenshot of it and upload it somewhere
| |
| 13:02 | <Ghidorah> http://pastebin.com/rbiNHn08
| |
| 13:03 | <Hyperbyte> How did you install this flash plugin?
| |
| 13:04 | <Ghidorah> I've tried it several ways now.
| |
| 13:04 | First apt-get install flashplugin-installer
| |
| 13:04 | I've tried it with apt-get install flashplugin-nonfree

| |
| 13:06 | <Hyperbyte> Have you tried fetching one directly from Adobe?
| |
| 13:06 | Also, there should be some messages about libflashplayer crashing somewhere
| |
| 13:06 | Either with command 'dmesg' or in '/var/log/syslog' (both on the client)

| 17:47 | <warren> who is doing all those PPA builds with mail going to ~ltsp-upstream?
| |
| 17:48 | I'm getting flooded with a ton of Ubuntu specific mail
| |
| 17:48 | it is highly improper to do it using the ~ltsp-upstream group for notification
| |
| 17:48 | <Hyperbyte> warren: stgraber explained in a mail to ltsp-developers
| |
| 17:49 | <warren> odd, I'm not on ltsp-developers anymore...
| |
| 17:51 | <Hyperbyte> <stgraber> The result is daily build packages for lucid, maverick, natty and oneiric showing up in: https://launchpad.net/~ltsp-upstream/+archive/daily/+packages
| |
| 17:51 | <stgraber> Once I'm done fixing the packaging and making sure everything builds, you should only receive e-mail for when there's an actual build failure
| |
| 17:51 | <warren> stgraber, could you please build it using an account that is NOT ltsp-upstream? this is totally irrelevant to other distros and quite annoying.
| |

| |
| 17:54 | <Hyperbyte> warren, according to stgraber the mails have quite distinctive headers, which make them easy to filter if you don't want them.

| 18:01 | roasted has joined IRC (roasted!~jason@206.82.22.190) | |
| 18:01 | <roasted> Is there a place anywhere that I need to change the IP of the server?
| |
| 18:02 | I'm running a server with 2 NIC's and my clients aren't PXE booting off it.
| |
| 18:02 | just curious if I need to bind to LTSP which IPs are being used, etc.
| |
| 18:03 | <Hyperbyte> roasted, your server needs to have a statically configured IP, else LTSP will not work.
| |
| 18:03 | <roasted> Hyperbyte, it does.
| |
| 18:03 | <abeehc> it'll work; not awesome practice though obviously
| |
| 18:03 | <roasted> sec, let me skip the switch thing and plug in my laptop directly to the server
| |
| 18:03 | and see if that boots
| |
| 18:04 | that way I can tell if its the box or the network
| |
| 18:04 | <Hyperbyte> abeehc, it won't work unless you hack dhcpd to point to different server automatically, as well as regenerate ssh keys and client image on every new IP.
| |
| 18:04 | <abeehc> yep
| |
| 18:05 | hacking dhcpd is pretty much the ticket
| |
| 18:05 | <alkisg> ip -oneline -family inet addr show
| |
| 18:05 | netstat -nap | grep :67
| |
| 18:05 | Those should reveal the problem...
| |
| 18:05 | <roasted> doesnt work with my laptop plugged in directly
| |
| 18:08 | I'm not using this server for dhcp. I have commented lines in my ltsp dhcpd.conf because I originally thought I was.
| |
| 18:08 | wonder if that's why
| |
| 18:09 | <alkisg> Hehe... that was some vital info missing there :D
| |
| 18:09 | <roasted> I had forgotten about it to be honest. :P
| |
| 18:09 | <alkisg> So troubleshooting the dhcp server should come first
| |
| 18:09 | <roasted> I had one of those "wait a minute, why isn't dhcp running"
| |
| 18:10 | I'm tempted to fire up dhcp on this server actually
| |
| 18:10 | to test
| |
| 18:10 | but that may make a mess
| |
| 18:14 | <abeehc> it is worth properly understanding dhcpd; hacking or otherwise
| |
| 18:14 | there are ways to not make a mess

| 18:26 | <roasted> abeehc, yeah, I had just forgotten that we switched it up at the last minute
| |
| 18:26 | abeehc, however, I'm thinking it'd just be easier to implement dhcp on the ltsp servers
| |
| 18:26 | and let them run in their own subnet
| |
| 18:28 | seems strange that eth0 is configured for a static IP yet it pulled a DHCP addy
| |
| 18:30 | leio has left IRC (leio!~leio@gentoo/developer/leio, Remote host closed the connection) | |
| 18:30 | <abeehc> it seems impossible
| |
| 18:31 | am i mistaken in thinking currently you are using windows dhcpd?
| |
| 18:31 | i'd go with it on the ltsp servers too in that case.
| |
| 18:31 | <roasted> yeah, my interface config file is 17.2 for eth0, yet it just pulled a 17.11
| |
| 18:31 | which our range is 17.10 to 17.254
| |
| 18:32 | its set to static in the interface file. net manager uninstalled.
| |
| 18:32 | I just restarted the net services and now its 17.2 as it should be
| |
| 18:32 | it just shocked me to see 17.11 when it clearly was 17.2 in the config file
| |
| 18:32 | leio has joined IRC (leio!~leio@gentoo/developer/leio) | |
| 18:32 | <roasted> but yeah, we're using windows dhcp :( I think it'd be cleaner to use ltsp for dhcp in its own subnet

| 18:53 | <Ghidorah> roasted: I'm using windows dhcp without issues with LTSP.
| |
| 18:54 | granted every ltsp client gets a reservation.
| |
| 18:56 | <roasted> Ghidorah, just got one working
| |
| 18:56 | one lab anyway
| |
| 18:56 | I have two labs off this server, with each lab being in its own subnet
| |
| 18:56 | the other still isnt working though
| |
| 18:57 | I'd much rather have ltsp do the dhcp, though
| |
| 19:03 | <alkisg> This way you can have a windows server, and manage everything on the ltsp server instead: https://help.ubuntu.com/community/UbuntuLTSP/ProxyDHCP
| |
| 19:15 | <roasted> where are ltsp logs stored? Im getting images to boot from one subnet, but not the other.
| |
| 19:16 | <alkisg> There are no ltsp logs related to booting
| |
| 19:16 | If you mean dhcp logs or tftp logs or ... then look at daemon.log
| |
| 19:16 | Or just paste the exact error that you're seeing on the client, that will help more :)
| |
| 19:21 | <jhutchins> If you run dhclient on a static-configured interface it will override the static address.
| |
| 19:27 | <Ghidorah> Does anyone know if you have to copy the public/private keys from italc-master into the italc-client (in chroot)?
| |
| 19:38 | <alkisg> Ghidorah: there are 2 ways to install italc. First, the easiest, is to just install it on the server.
| |
| 19:38 | Second method = install it to the chroot as well
| |
| 19:38 | In the second method you need to copy the keys, yeah
| |
| 19:41 | <Ghidorah> Thank you sir.
| |
| 19:43 | alkisg: if I install it via option 2 do I still need to install italc-client on the server?
| |
| 19:44 | <alkisg> apt-cache show italc-master | grep Depends ==> you'll see there that's a dependency
| |
| 19:44 | So you cannot have italc-master without the client
| |
| 19:45 | <abeehc> i'm having mostly random non-booting clients with a new lucid server i did recently; primarly done following the existing ubuntu ltsp fat client instructions - maybe something along the lines of lp 589034?
| |
| 19:46 | <Ghidorah> Thank you for supplying the command, it is very helpful.
| |
| 19:49 | <alkisg> abeehc: it's been causing problems in many setups, so remove nbd-proxy and see if the problem persists
| |
| 19:51 | <abeehc> well that's the thing i did roll through your instructions and still persists .. i replaced that file, updated initramfs and ltsp-update-kernsl then i modified the pxelinux.cfg/default
| |
| 19:51 | i removed queit splash at that point to so I know that part worked
| |
| 19:51 | short of a way to confirm i did properly disable nbd-rpoxy i'll try those isntructions again sfrom the start
| |
| 19:51 | <alkisg> abeehc: to check if it worked, run `ps -ef | grep proxy` on a localxterm
| |
| 19:51 | !localxterm
| |
| 19:51 | <ltsp> alkisg: localxterm: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client..
