| 00:32 | <jimjimovich> anyone know how to disable the system error "beep" on ubuntu ltsp? it's about 100 times louder than any other sound and scares people because it's so loud.
| |
| 00:38 | BenG has joined #ltsp | |
| 00:42 | <muppis> jimjimovich, do you mean tha one what comes out from pc-speaker, not from soundcard?
| |
| 00:42 | <jimjimovich> muppis: it comes out of the sound card
| |
| 00:43 | <muppis> jimjimovich, have look from soundsettings?
| |
| 00:43 | <jimjimovich> yeah, i have all system sounds turned off
| |
| 00:46 | <muppis> Using some branded HW, like HP, Dell... ?
| |
| 00:47 | <jimjimovich> muppis: no, it's on all the terminals, and they're all random generic PC parts
| |
| 00:47 | it makes the error noise, for example, when there is an error in the terminal (like if you're backspacing too far, etc)
| |
| 00:48 | or if you hit "tab" to complete something and there's an error
| |
| 00:50 | <alkisg> jimjimovich: in gnome-volume-control there's an option to mute alerts
| |
| 00:51 | vmlintu has joined #ltsp | |
| 00:54 | <BenG> I got my vserver based install of LTSP-5 almost completely working
| |
| 00:54 | one remaining issue is USB keys
| |
| 00:54 | I've seen there is some trouble with local devices in Squeeze
| |
| 00:54 | did anyone find the problem?
| |
| 00:55 | ltspfsmounter script looks sensible, but haven't a clue if it's working as meant to
| |
| 00:56 | I get a mount remote fs in /tmp/.<user>-ltspfs/usbdisksda1, but nothing in /media/
| |
| 00:56 | also the clean up doesn't work
| |
| 00:57 | <muppis> BenG, there can be missing something. Take a look Ubuntu's script, as it works.
| |
| 00:58 | <BenG> Debian packages are based on Ubuntu though
| |
| 00:58 | but yes, a good starting point would be to look at the differences
| |
| 01:05 | <muppis> jimjimovich, did you get it disabled?
| |
| 01:07 | <jimjimovich> muppis: got called away to another issue, will try now
| |
| 01:08 | <alkisg> jimjimovich: there's no need to mute it, you can just lower its volume if you want from the slider there.
| |
| 01:08 | <BenG> muppis, packages look identical, save for one file, which is purely documentation
| |
| 01:09 | <muppis> BenG, bummer. Any mark of failing in logs?
| |
| 01:09 | <BenG> no
| |
| 01:09 | also I don't have the system to hand, so it's very limited what I can now
| |
| 01:10 | I'm researching possibilities
| |
| 01:10 | do people has this working on both maverick and natty?
| |
| 01:10 | perhaps I'm missing a log file
| |
| 01:11 | I have syslog remotely logging on the server from each client, and I've looked at /var/log/ldm.log on the clients
| |
| 01:11 | <muppis> Got Maverick installed at home, but my thins mb failed so I can't test right now.
| |
| 01:11 | <BenG> anywhere else I should look?
| |
| 01:11 | <jimjimovich> alkisg: you talking about the "Alert volume" slider?
| |
| 01:11 | <alkisg> Yes
| |
| 01:11 | <jimjimovich> for some reason, I can't even replicate the problem now
| |
| 01:12 | <alkisg> cat sldkfjlskjd<tab><tab>
| |
| 01:12 | <muppis> BenG, how about serverside logs?
| |
| 01:12 | <BenG> what would log ltspfs though?
| |
| 01:12 | I'd love to see a direct output of ltspfsmounter as it ran
| |
| 01:13 | <jimjimovich> alkisg: yeah, that's what I did before and it would beep, now it doesn't beep for me at all. Thanks for the info though, now I'll know where to start next time it pops up.
| |
| 01:13 | <muppis> If there permission issue on server, then it logged on server. I think.
| |
| 01:14 | <alkisg> jimjimovich: there's a mute button there, if you clicked on it then it's completely disabled
| |
| 01:14 | <BenG> muppis, I have access to the logs from here
| |
| 01:14 | <jimjimovich> alkisg: yeah, I see that, muted or not, and changing the volume, no beep. it's strange.
| |
| 01:15 | <muppis> alkisg, do you know the trick for server without soundcard and Gnome?
| |
| 01:15 | <alkisg> muppis: what trick?
| |
| 01:16 | <muppis> alkisg, to mute that annoying beep..
| |
| 01:16 | <alkisg> muppis: it's a user setting, you can do that from any thin client
| |
| 01:16 | If you want to enforce a gconf default for all users, you can use gconftool-2 --direct etc
| |
| 01:17 | <muppis> alkisg, I meant at console ofregular server, not just ltsp.
| |
| 01:17 | <jimjimovich> okay, so i went to another terminal, and there, it beeps through the soundcard no matter if it's muted or not (and the volume control has no effect)
| |
| 01:17 | <alkisg> muppis: you mean the pc speaker beep? That's a different problem...
| |
| 01:17 | muppis: disconnect the speaker? :D
| |
| 01:18 | <jimjimovich> the problem is that the beep is incredibly loud, much louder than any other sounds on the speakers
| |
| 01:18 | <muppis> alkisg, well.. HP service wont be happy then..
| |
| 01:18 | <alkisg> jimjimovich: what about the *global* volume control? Does it lower that beep's volume?
| |
| 01:18 | <jimjimovich> tried that too, and it doesn't have any effect
| |
| 01:18 | <alkisg> muppis: no idea, maybe you can blacklist the pc speaker module
| |
| 01:19 | jimjimovich: then it's the internal speaker in your case too
| |
| 01:19 | It's not the soundcard
| |
| 01:19 | <jimjimovich> it's the speakers connected to the soundcard
| |
| 01:19 | <alkisg> jimjimovich: it's possible that the pc speaker gets directed through the soundcard
| |
| 01:19 | <jimjimovich> hmmm
| |
| 01:19 | <alkisg> If the master volume has no effect in it, then that's what's probably happening
| |
| 01:19 | <muppis> jimjimovich, onboard soundcard?
| |
| 01:19 | <alkisg> Try removing the pc speaker module
| |
| 01:19 | <jimjimovich> yes, onboard
| |
| 01:20 | i wonder if the bios has a way to turn it off. they are intel boards with atom processors
| |
| 01:20 | <muppis> Propably not.
| |
| 01:20 | <jimjimovich> how would you remove the pc speaker module?
| |
| 01:20 | <alkisg> modprobe -r
| |
| 01:21 | (locally on the client, not on the server)
| |
| 01:21 | <jimjimovich> in the chroot then?
| |
| 01:21 | <alkisg> (i.e. you'd blacklist it on the chroot if that works)
| |
| 01:21 | !SCREEN_02
| |
| 01:21 | <ltspbot`> alkisg: "SCREEN_02" :: to get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using%20a%20shell%20SCREEN
| |
| 01:21 | <jimjimovich> ah, got ya
| |
| 01:21 | <alkisg> That's how to test if it works ^^
| |
| 01:21 | Then if you make it work from the command line, you blacklist it in the chroot
| |
| 01:22 | blacklist pcspkr or something like that

| |
| 01:26 | mistik1 has quit IRC | |
| 01:36 | <jimjimovich> alkisg: yeah, it doesn't work to remove that mod. according to the bug you posted, that's what other people experienced too. it only silences the actual internal speaker (of which there is none, in my case)
| |
| 01:36 | <alkisg> Strange, I'd expect that it doesn't allow port 0x61 output after that
| |
| 01:37 | (that's where the speaker sound is controlled from)
| |
| 01:37 | <jimjimovich> in the bug, people are saying that the beep still comes through speakers and headphones
| |
| 01:37 | <alkisg> I see. Then maybe some other module is responsible for that.
| |
| 01:38 | Try asking in #ubuntu
| |
| 01:44 | <jimjimovich> alkisg: yeah, I'll ask over there. it's kinda crazy. pcspkr is actually disabled by default. also it's interesting that in screen 02, the beep is a different sound than in the normal ltsp environment
| |
| 01:45 | <alkisg> Hmmm then it probably isn't related to your pc speaker
| |
| 01:46 | The local pc speaker beep is the one from screen_02
| |
| 01:48 | <jimjimovich> the screen_02 beep also comes through the speakers, but sounds more like a pc beep. the one in the full gnome interface is less annoying sounding but extremely loud

| 03:27 | <BenG> okay, question about usb keys, when the icon pops up on the gnome desktop showing you the key, how does it find it?
| |
| 03:27 | how does gnome know about the key?
| |
| 03:35 | <johnny> because the client connects to the server and hooks up a directory in /media
| |
| 03:35 | and gnome knows about /media
| |
| 03:46 | bobby_C has quit IRC | |
| 03:48 | <BenG> johnny, it's the "knows about" bit I want to understand
| |
| 03:48 | also wondering why I don't get proper mounts in /media
| |
| 03:50 | <johnny> that's a gnome question, you'd have to read more about that
| |
| 03:50 | and also read about ltspfs
| |
| 03:51 | and possibly reading the source
| |
| 03:53 | <BenG> yep, read the ltspfsmounter script this morning
| |
| 03:53 | looks like it should work :)
| |
| 03:53 | reading on the gnome-volume-manager for clues too, but might have the wrong end of the stick
| |
| 03:54 | or indeed completely the wrong stick

| 04:45 | <jimjimovich> alkisg and muppis: I found the solution to the beep problem if you need it.
| |
| 04:45 | shamino has joined #ltsp | |
| 04:46 | <alkisg> jimjimovich: well out of curiosity, sure, say it...
| |
| 04:46 | <jimjimovich> need to add "set bell-style none" to /etc/inputrc in chroot (I did it on the server too)
| |
| 04:47 | shamino has quit IRC | |
| 04:47 | <jimjimovich> or you can do "set bell-style visible" to get a visible indicator of the error
| |
| 04:47 | shamino has joined #ltsp | |
| 04:47 | <alkisg> Isn't that for "readline" only? That won't affect GUI apps...
| |
| 04:47 | shamino has quit IRC | |
| 04:47 | <jimjimovich> well, it works
| |
| 04:48 | no more beeps
| |
| 04:48 | shamino has joined #ltsp | |
| 04:48 | <alkisg> ok, thanks for sharing

| 05:09 | <elias_a> Hello, folks!
| |
| 05:11 | A friend of mine has problems with HP Compaq D51S as thin clients: the user is spontaneously logged out of the session and returned to login screen. Any similar experiences?
| |
| 05:14 | My friend says that the logout occurs after 1-2 hours of use. All clients of this type behave in the same way. Other TC's work ok.

| |
| 07:00 | usb keys mounting on the desktop is the problem
| |
| 07:00 | they aren't finding their way to /media for a start

| 07:47 | <dgroos> Hi
| |
| 07:48 | I've got a classroom set of thin clients (old p4's) using localapps for firefox.
| |
| 07:48 | It works great.
| |
| 07:49 | <mgariepy> morning everyone
| |
| 07:49 | <dgroos> I have made instructional videos for students to help them learn how to use different tools.
| |
| 07:49 | Howdy mgariepy
| |
| 07:50 | <highvoltage> morning mgariepy and dgroos
| |
| 07:51 | <dgroos> Flash and sound work great, the problem is that when a student plugs in a headphone, while sound comes out of the headphone, it *still* comes out of the speaker on the computer! This is distracting!
| |
| 07:51 | Morning highvoltage--kinda early out west there?
| |
| 07:52 | <highvoltage> dgroos: 8:52
| |
| 07:52 | <mgariepy> maybe you need to load the soundcard module with some option
| |
| 07:52 | <dgroos> Hmmm I thought you were in western Canada...
| |
| 07:52 | <highvoltage> dgroos: nope, east :)
| |
| 07:53 | dgroos: I favourited some instructional videos on youtube just yesterday: http://www.youtube.com/user/edubuntuproject
| |
| 07:53 | they're quite nice, just a pity about the bad sound quality
| |
| 07:53 | <mgariepy> sometimes the card doesn't detect correctly when the headphone is plugged-in and doesn't mute the other channel.
| |
| 07:53 | <highvoltage> dgroos: if any of yours are on youtube, let me know and I'll add it too
| |
| 07:54 | <dgroos> mgariepy--I'll check into sound cards after school, thanks. Interesting that almost all google hits about sound issues seem to be from Hardy or earlier days...
| |
| 07:55 | highvoltage: Unfortunately I can't even check out those videos now as my district blocks youtube :( though can on cell :)
| |
| 07:56 | <highvoltage> dgroos: heh, ok
| |
| 07:58 | <dgroos> Here are 3 that I made for today--posted them on a wiki supplied to me by the district... http://wiki.mpls.k12.mn.us/groups/gcos/wiki/42568/FLE4.html They are not exciting but do what I need them to do.
| |
| 08:01 | mgariepy: do you have any favorite pages that explain the process of ltsp-soundcards-localapps-lucid? This one will be helpful, I believe: http://manpages.ubuntu.com/manpages/lucid/man5/lts.conf.5.html
| |
| 08:07 | Gadi has joined #ltsp | |
| 08:10 | <dgroos> I wonder what percentage of school districts in US and other countries block youtube?
| |
| 08:11 | <highvoltage> I guess quite a lot, considering just the amount of bandwidth it eats
| |
| 08:11 | <mgariepy> sorry dgroos i don't have documentation on soundcard i just remember we had a few problem back on interpid or something like that
| |
| 08:13 | <dgroos> hmmm... I know that there are commands to find out one's soundcard and that I can find docs about finding and installing drivers, I'm just wondering how configure. Maybe I'll be back here after school :)

| 09:21 | <Mip5> G'morning all - LTSP on 10.04, dual xeon 3 GHz, RAID1, 8 gb ram. I lost connection to the server doing a dist-upgrade to get the new kernels. I was able to get back in and ssh, but couldn't reconnect to apt-get session (didn't know how). I restarted, and ran dpkg --configure -a to resume.
| |
| 09:22 | It appeared to work, GRUB ncurses screen came up, I installed it on all 3 disks in the RAID, it appeared to successful. On a reboot, I'm stuck at the initramfs. Any ideas? TIA
| |
| 09:25 | <Gadi> any errors before the initramfs prompt?
| |
| 09:26 | <Mip5> Yes - one about udev, I think. Can I scroll back on this console screen, or should I reboot and look again (this happened last night)
| |
| 09:28 | <Gadi> try shift-pageup to scrool
| |
| 09:28 | *scroll
| |
| 09:29 | <Mip5> shift page up didn't do it, but I just remembered this: ALERT! /dev/disk/by-uuid/3 does not exist. Dropping to a shell.
| |
| 09:29 | litlebuda has joined #ltsp | |
| 09:30 | <Mip5> That's a search string I put - uuid was long, and contained my unique blkid
| |
| 09:30 | <Gadi> ah, seems initramfs is looking for a device that does not exist
| |
| 09:30 | and I doubt your uuid is actually 3
| |
| 09:30 | <Mip5> yeah, sorry.
| |
| 09:30 | <Gadi> do: ls /dev/disk/by-uuid
| |
| 09:31 | <Mip5> No such file or directory found
| |
| 09:31 | I tried searching /dev/ for md* or disk* - no luck
| |
| 09:32 | <Gadi> software RAID or hardware?
| |
| 09:32 | <Mip5> Software
| |
| 09:33 | <Gadi> ah
| |
| 09:33 | hmm...
| |
| 09:34 | have you tried loading an older kernel?
| |
| 09:34 | <Mip5> no - but I don't even get to a grub menu - so I'm not sure how I'd do that.
| |
| 09:34 | <alkisg> Press left shift while booting
| |
| 09:35 | <Mip5> alkisg: I assume I'd hit shift after the scsi stuff?
| |
| 09:35 | <highvoltage> or just keep it in all the way
| |
| 09:35 | <alkisg> Mip5: when you see the white BIOS letters, press shift and keep it pressed
| |
| 09:36 | <Mip5> ok - here goes - it takes a while....

| |
| 09:41 | <Gadi> Mip5: I suggest you boot from a livecd, get the raid array mounted, chroot into it, and do a dist-upgrade
| |
| 09:42 | FYI: "dpkg --configure -a" will fix partially installed packages, but it will not finish a dist-upgrade
| |
| 09:43 | <Mip5> Rats - I don't have a cd drive on this hardware, and I haven't been able to get it to boot from usb thumb drive. I have access to usb drive though (in another building). Is there no way to chroot into it from here (initramfs)?
| |
| 09:43 | <Gadi> in the future, run apt-get dist-upgrade again after that
| |
| 09:43 | Mip5: only if you can get the chroot to load the proper drivers and recognize the disk
| |
| 09:44 | but, seeing as that is the problem to begin with....
| |
| 09:44 | :)
| |
| 09:45 | <mgariepy> Mip5, don't you have an older kernel you can boot on the system ?
| |
| 09:45 | <Mip5> Ah - okay - thanks. I'll go get the drive, and check in with y'all when I get back. Thanks *so* much for your help.
| |
| 09:45 | mgariepy: I don't know how to get to it. I don't get a grub menu, and holding down shift didn't seem to stall the process - I still got dropped to the initramfs shell (busybox)
| |
| 09:46 | <mgariepy> ok
| |
| 09:46 | <Mip5> Back in a bit - thanks again

| 10:04 | <Mip5> Gadi: I'm back at the office. Which disk should I have with me when I get back to the server? Initially I used an alternate 10.04
| |
| 10:05 | gnunux has quit IRC | |
| 10:05 | <Gadi> you can probably use anything. maybe easier for you if it brings up a gnome desktop that automounts the drive
| |
| 10:05 | then, you can just open a terminal window and chroot into it
| |
| 10:06 | <Mip5> so 10.04 desktop would do the trick
| |
| 10:06 | ?
| |
| 10:06 | <Gadi> I think so - bring both
| |
| 10:06 | :)
| |
| 10:06 | <Mip5> ok!
| |
| 10:11 | MorningSon has quit IRC | |
| 10:12 | <alkisg> Mip5: you can also use network booting if cd / usb won't work
| |
| 10:12 | https://wiki.ubuntu.com/LiveCDNetboot#line-77
| |
| 10:19 | <Kyle__> alkisg: For the base install? It works, but it is a bit of a pain, and depending on your connection, it can be painfully slow. (I did that before I tried LTSP).
| |

| 10:29 | <alkisg> Kyle__: no, for booting a live usb served from a different pc on the local network
| |
| 10:29 | E.g. if you want to install ubuntu on 12 netbooks, you can use that
| |
| 10:30 | Much much faster than usb, even for 1 netbook
| |
| 10:30 | It's so handy I've even scripted it into 1 single command ;)

| 11:12 | <Mip5_> Gadi: my machine is booting the desktop install now, I selected "Try" ubuntu, and am awaiting the desktop
| |
| 11:17 | Gadi: /dev/disk/by-id shows the bare drives in my raid array, and also shows the separate partitions. I don't see /dev/md0, which is my root partition. Not sure what to do next, but I'm thinking I'm going to have get mdadm going
| |
| 11:19 | Question for anyone - does an italicized / grayed out username indicate the user is offline?
| |
| 11:22 | <dberkholz> in most clients that would indicate away
| |
| 11:22 | <Mip5_> ok - thanks
| |
| 11:22 | <dberkholz> the user wouldn't show up in the list if offline
| |
| 11:22 | <Mip5_> Ah - that makes sense
| |
| 11:22 | <dberkholz> try right-clicking on a user and see if it will show you an away message
| |
| 11:27 | <Mip5_> Anyone have an idea of how to mount a software raid array from a live cd?
| |
| 11:39 | <Kyle__> Mip5_: You need to make sure that the kernel has the software-raid drivers.
| |
| 11:40 | Mip5_: Modern kernels autodetect some (most? all?) types of mdadm devices, so if there are no /dev/md devices, you need to modprobe the drivers, or use a different live-cd.
| |
| 11:41 | <Mip5_> Thanks - what parameters should I use on modprobe?
| |
| 11:42 | <Kyle__> Mip5_: It's been so long, I can't actually recall. Google for a linux-software-raid howto. Look for the kernel modules.
| |
| 11:42 | <Mip5_> ok - thanks

| |
| 12:59 | <Mip5_> I've chrooted into my /dev/md0, my system root. Anyone know how to verify that GRUB is setup correctly?
| |
| 13:00 | One other thing - when I was running 9.04 on this same box, (using old grub), I had a rootdelay=200 entry there so that the system would wait to see the root filesystem. I haven't had to do that since moving to 10.04, but I don't even know *how* to do that in GRUB2. Ideas?

| 13:06 | <cody_> on a fresh install of 10.10 I get Error: failed to connect to NBD server, even though I can see it is spawning a nbd session on the server

| |
| 13:20 | Do I have to specifically mount /dev in this chrooted environment? I guess I'm confused. I thought I was running from the chroot, in which case, /dev (and the things I see there) are already available to the system. Any ideas?
| |
| 13:39 | Gadi - you there? Any chance we can pick this back up?
| |
| 13:42 | <alkisg> rootdelay=200? Pause for 3 minutes before mounting the root file system?!
| |
| 13:42 | https://wiki.ubuntu.com/Grub2#Recover Grub 2 via LiveCD
| |
| 13:42 | <ogra_ac> ugh
| |
| 13:42 | <alkisg> See how to mount /dev etc and chroot there
| |
| 13:43 | <ogra_ac> dont use rootdelay
| |
| 13:43 | way obsolete
| |
| 13:43 | just use rootwait
| |
| 13:44 | <johnny> ogra, obsolete rootwait and rename it to rootstandstill
| |
| 13:46 | <Mip5_> Thanks - so I'd swap out rootdelay=200 for rootsandstill (and not provide any other parameter)?
| |
| 13:50 | <alkisg> Mip5_: johnny was just joking
| |
| 13:50 | The parameter name is rootwait
| |
| 13:52 | <Mip5_> oh - thanks,...
| |
| 13:53 | [GuS] has quit IRC | |

| 14:48 | <Mip5_> alkisg: I've read the wiki and have been successful up until grub-install - I'm not sure how to specify this with my software raid disks. I tried using grub-install /dev/md0, and got the error (Attemping to install GRUB to a partition instead of the MBR. This is a BAD idea.
| |
| 14:49 | alkisg: followed by embedding is not possible , but this is required when the root device is on a RAID array
| |
| 14:50 | alkisg: I was able to execute update-grub after editing the /etc/default/grub file. Maybe that will do the trick anyway....

| |
| 14:57 | Are they Debian guys, Ubuntu guys or mostly who?
| |
| 15:02 | <Mip5_> alkisg: if you're still around, I'm still getting dropped to the shell (initramfs), but at least I'm now seeing GRUB. I guess I'll try to boot the previous kernel .... I'm happy to see GRUB, so this feels like some success (btw - same error as before can't find disk by-uuid - is the last error I see before the shell
| |
| 15:06 | vagrantc has joined #ltsp | |
| 15:09 | <Mip5_> Booting to the other options doesn't seem to help. Given that it's saying it can't find disk-by-uuid-xxxx, should I try using the /dev/md0 instead?

| 16:01 | <Mip5_> alkisg: do you mean use /dev/md0 in /etc/fstab?

| |
| 16:02 | In the initramfs prompt, can you see the raid disk?
| |
| 16:02 | <Mip5_> I can't see /dev/md0, which is the raid disk, from initramfs
| |
| 16:04 | <alkisg> I've never used a software raid so I can't help you there, but trying to see the disk from the initramfs sounds like the way to go there. Try asking in #ubuntu or in #ubuntu-server.

| |
| 16:54 | <alkisg> What does it give you if you don't put anything in lts.conf?
| |
| 16:54 | (in that case screen=ldm is used)

| |
| 16:55 | screen = ldm is not used, I mean

| |
| 22:52 | <johnny> depends on the clients
| |
| 22:52 | it's really more about ram than anything else
| |
| 22:53 | you want 256 + (192 * clients)
| |
| 22:54 | alkisg has joined #ltsp | |
| 22:54 | <johnny> of coruse.. that also depends on the workload.. that's a minimum there

| 23:02 | <Naruni> yeah probably the same stuff, only thing they use different is a win32 application that calculates loan payments and junk
| |
| 23:03 | <johnny> no.. i mean.. i had to run those apps on teh server
| |
| 23:03 | so i do't really know what it actually looks like to run a normal ltsp setup :)
| |
| 23:03 | <Naruni> ok so if there are 3 clients all running firefox, the server has to be running firefox 3 times?
| |
| 23:03 | <johnny> with an unladen server.. no personal experience
| |
| 23:03 | <Naruni> ah i get it now
| |
| 23:04 | <johnny> in my case. .it would be 4 firefoxes :)
| |
| 23:04 | it was the main computer at a coffeeshop
| |
| 23:04 | and there wasn't much room for other server hardware to go.. just room for the 3 public internet terminals
| |
| 23:04 | originally they were various donated pcs .. i ran through eight of those as more people kept donating
| |
| 23:04 | i even had a gumdrop imac once
| |
| 23:05 | <Naruni> what were you using as a server?
| |
| 23:05 | <johnny> 2gb ram (it's now 3gb) .. and some sort of dual core athlon
| |
| 23:05 | x2 maybe?
| |
| 23:05 | i don't really remember
| |
| 23:06 | i never really considered the cpu speed to be the blocker (except in the case of flash.. FLASH IS THE WORST)
| |
| 23:06 | so i started by trying to run firefox and flash locally on the client pcs
| |
| 23:06 | <Naruni> if you dont mind me asking, did you get paid to set this up? and did you have to ever service call
| |
| 23:06 | <johnny> since the music on the server would get skipped
| |
| 23:06 | if the people on the terminals were watching youtube or whatever
| |
| 23:06 | <Naruni> yeah flash sucks
| |
| 23:07 | <johnny> so.. i had say .. 2 p3s witth 512mb ram and a p4 with 128mb ram :)
| |
| 23:07 | err .. sorry .. 256.. not 128..
| |
| 23:07 | i added 128 more..
| |
| 23:08 | but.. it was still too much load on the server.. so with the tech budget i get, i saved up enough and bought 3 new dual core atom boxes (msi wind) and loaded em up with 2gb ram (it was only $15 more than 1gb)
| |
| 23:08 | and now they run the os completely locally
| |
| 23:08 | the server machine os only exists to serve up the images and save the client machine /home directories
| |
| 23:08 | <Naruni> yeah thats the kinda setup i want
| |
| 23:09 | <johnny> we call that fat client
| |
| 23:09 | <Naruni> those dual core atoms are pretty decent, but how are they running flash (youtube and such)
| |
| 23:09 | <johnny> you'd want 512mb ram on the clients for that
| |
| 23:09 | ah.. just fine i think
| |
| 23:09 | ram is really the problem..
| |
| 23:09 | cpu speed not so much for that.. since everything atom was already 1ghz..
| |
| 23:10 | and it matters more in ltsp when running things locally, as you don't want to use network swap if you don't have to
| |
| 23:10 | in that case.. the server box can be really minimal
| |
| 23:13 | <Naruni> running the OS on the client... how does that happen?
| |
| 23:13 | <johnny> oh.. you asked how much i set it up for.. ah.. it's a business i'm coowner of
| |
| 23:13 | <Naruni> yeah im trying to get into that business 8)
| |
| 23:13 | <johnny> well in regular ltsp, you do run an os anyways.. just enough of one to be abl to connect to the server
| |
| 23:13 | <Naruni> oh nevermind not the coffee business
| |
| 23:13 | <johnny> coffeeshop?
| |
| 23:14 | <Naruni> stripclub
| |
| 23:14 | j/k
| |
| 23:14 | <johnny> no.. i mean i coown the coffeeshop, i'm on the tech committee
| |
| 23:14 | there are quite a few other owners
| |
| 23:14 | i rarely ever get support calls
| |
| 23:15 | <Naruni> so on a client boot, does it call the DHCP server and get a pxe boot command? or does it boot into a OS stored on the client?
| |
| 23:15 | <johnny> at least once i switched to the new hardware..
| |
| 23:15 | the first
| |
| 23:15 | in both regular ltsp, and this
| |
| 23:15 | this use the same base layer for what regular ltsp uses, it just adds more packages, and tells it to boot the local install
| |
| 23:15 | instead of trying to connect to the remote server
| |
| 23:15 | but it's still retrieved in the same way
| |
| 23:23 | <Naruni> interesting
| |
| 23:23 | thank, gnight
