| 03:32 | <lfs> hi
| |
| 03:33 | i have dobt about dhcp configuration
| |
| 03:34 | anybody will help me out.
| |
| 03:34 | how to create new interfaces in dhcp.conf file
| |
| 03:34 | <alkisg> lfs: be more specific, it'll be easier to get any answers...
| |
| 03:34 | <lfs> ok
| |
| 03:35 | <alkisg> Network interfaces are declared in /etc/network/interfaces, not in /etc/ltsp/dhcpd.conf
| |
| 03:36 | <lfs> i mean to run dhcp server we first change the configuration file
| |
| 03:36 | there i'm not able to create conf file
| |
| 03:38 | syslog is saying that i'm not having subnet declaration file for my ip
| |
| 03:40 | can u give me the format for new subnet declaration in configuration file
| |
| 03:40 | <alkisg> There is an example subnet in the default /etc/ltsp/dhcpd.conf
| |
| 03:40 | But I'
| |
| 03:41 | But I'm not sure I understand what you want to do
| |
| 03:41 | <ogra> or what you did already
| |
| 03:41 | <alkisg> Can you upload those 2 files? /etc/network/interfaces and /etc/ltsp/dhcpd.conf in http://pastebot.ltsp.org ?

| 14:02 | <beer30> If anyone has experience with running ltsp-build-client in Gentoo, please help! I have been trying to runt ltsp-build-client for 2 days now and everytime it errors out when trying to build the kernel. The specific message is: "/var/tmp/spawn.sh: line 2: genkernel: command not found". The ODD part is that genkernel IS installed, but it gets installed to the wrong directory. In fact, it appears that when genkernel is installed there is a dou
| |
| 14:06 | I don't know if this is a quickstart profile.qs problem, a quickstart module problem, or something completely different. I have tried specifically adding a 'spwan_chroot "emerge --nodeps genkerenel" to the profile.qs, but it still ends up getting put into the wrong directory (/opt/ltsp/x86/opt/ltsp/x86/).
| |
| 14:08 | If anyone has any sugguestions, tips, questions... drop 'em in here. I will be hanging out in #ltsp for the next few days until I can get this resolved. Thx!

| 15:54 | <Ahmuck> beer30: use ubuntu :)
| |
| 15:55 | beer30: from the topic "Gentoo is close", whereas Ubuntu, Debian, Fedora - awesome
| |
| 16:13 | <beer30> ya, I've tried ubuntu and I might have to go with it, but I am stubborn and I can't give up on Gentoo just yet ;).
| |
| 16:14 | <alkisg> beer30: have you talked to johnny? He's the gentoo guy...
| |
| 16:14 | <beer30> no, I was hoping he'd pop in here this weekend, but haven't seen him yet.
| |
| 16:14 | <alkisg> !seen johnny
| |
| 16:14 | <ltspbot> alkisg: johnny was last seen in #ltsp 4 days, 4 hours, 7 minutes, and 4 seconds ago: <johnny> and that would be annoying on a terminal wouldn't it :)

| 16:31 | <beer30> maybe he'll pop in here this week sometime. I've kinda hacked my way around getting it to install, but keep running into walls. finally got it to build the kernel, but I had to do some manual intervention.... now it is building a whole bunch more more stuff... so I guess we'll wait and see if it finishes this time.
| |
| 16:34 | btw, the thing I didn't like about ubuntu was that my server has a crappy apseed video driver and ubuntu doesn't have drivers for it, and vesa doesn't want to work, so I had to use fbdev?! (framebuffer)... knowning darn well that the server will not be accessed on a daily basis, but the fact that it didn't have the AST drivers really bugged me ;). Don't have to worry about that with Gentoo.

| 16:38 | <beer30> OH, and get this... I wanted to try Debian 5 (lenny), but the installer would not setup/recognize my raid, so I tried a unstable iso... it worked great with my raid, but it would not recognize my NICs!!!... I guess I could download the entire 5/6 DVDs (instead of doing netinstall) and worry about getting the network installed after the fact, but 'cmon! ;)

| 17:54 | <beer30> Has anyone tried ltsp w/ fedora 11? I was waiting on the "F-11 final coming mid-June 2009" K12Linux Live Server (which never came), to try it out. Turns out (after trudging thru the mailing list) that he (the maintainer) didn't have time to do the spin, but he said you could just install ltsp in fed11 "in the usual way"... I wouldn't mind trying it, but not sure what the "usual" way is. Any howtos/guides out there? Seems most information I
| |
| 17:56 | I regress... it is the "other" way ;) Here is the quote: "Things are busy, I didn't spin a final. You could just install K12Linux the other way and get the latest version.

| |
| 17:57 | bobby_C has quit IRC | |
| 18:01 | <beer30> also... can I just use the Fedora-11-x86_64-Live.iso, or do I have to download the whole 4G DVD?

| 20:16 | <ball> Why does the application server have to run NFS?
| |
| 20:16 | Selveste1 has joined #ltsp | |
| 20:25 | vvinet has quit IRC | |
| 20:27 | <beer30> ball: that is how the thin client gets its initial root directory structure.
| |
| 20:28 | <ball> beer30: is NFS optional if the thin client can have everything in flash?
| |
| 20:30 | <beer30> ya, I don't think nfs is needed after the client boots, so ya, if the thin client already has it's root dir in flash nfs should not be needed.
| |
| 20:31 | <ball> Hmm... now I have to decide which way I want to do that.
| |
| 20:31 | <beer30> I haven't done this with ltsp5 yet, but I did load the ltsp4 root dir stuff on a pen drive and it works w/o nfs or dhcp (I statically set the ip address on the usb stick).
| |
| 20:32 | <jammcq> If it's got the root fs in flash, then it's not LTSP
| |
| 20:32 | <ball> I have some boards that can PXE boot, perhaps I'm best off tolerating NFS on the terminal LAN
| |
| 20:32 | <jammcq> ball: what distro are you using?
| |
| 20:32 | <ball> jammcq: I haven't decided yet, but perhaps Ubuntu Server
| |
| 20:33 | <jammcq> Ubuntu doesn't need NFS. It uses NBD for the root filesystem
| |
| 20:33 | Debian is still using NFS as far as I know
| |
| 20:33 | <ball> NBD = network block device? <- wild guess
| |
| 20:33 | <jammcq> yep
| |
| 20:33 | turns out to be faster at serving thin client root filesystems images than NFS
| |
| 20:34 | <ball> Faster and less insecure?
| |
| 20:34 | <jammcq> well... NBD is a pretty simple protocol, so it seems that it should be less insecure
| |
| 20:38 | <beer30> jammcq: can't you still have the initial boot stuff on say a flash drive and still use the ltsp stuff for the rest of it and still esentially have ltsp?
| |
| 20:38 | <jammcq> LTSP IS the root filesystem
| |
| 20:38 | anything else is just an X terminal
| |
| 20:38 | <ball> I may have to reinstall the server for ltsp, but that shouldn't be too painful.
| |
| 20:38 | jammcq: any advantages to LTSP over a traditional X terminal?
| |
| 20:39 | <jammcq> LTSP supports local devices, local applications, audio
| |
| 20:39 | try2free has joined #ltsp | |
| 20:39 | <ball> local devices as in storage?
| |
| 20:39 | Selveste1 has quit IRC | |
| 20:40 | <jammcq> yeah, usb thumb drives, cdroms, floppies
| |
| 20:40 | <ball> Are those exported via nfs?
| |
| 20:40 | <jammcq> nope. ltspfs
| |
| 20:40 | built on top of fuse
| |
| 20:40 | * ball writes that down | |
| 20:40 | <jammcq> nfs doesn't handle removeable media very well
| |
| 20:40 | <ball> What protocol is used for sound?
| |
| 20:41 | Selveste1 has joined #ltsp | |
| 20:41 | <jammcq> pulse audio
| |
| 20:41 | <ball> Thanks
| |
| 20:41 | Does LTSP support Xvideo and AIGLX?
| |
| 20:41 | <jammcq> i'm pretty rusty on how all that works. I've not done actual work on LTSP for a couple years now
| |
| 20:42 | yeah, there's a way to do the fancy blingy stuff
| |
| 20:42 | but others will have to tell you how
| |
| 20:42 | <ball> ok
| |
| 20:42 | Wasn't sure whether I could expect it to "just work"
| |
| 20:44 | If I could bring up LTSP tonight, I could test things like that out.
| |
| 20:44 | * ball ponders. | |
| 20:44 | <ball> First step is to backup my old Web server and to burn myself a new Ubuntu CD.
| |
| 20:44 | <beer30> ubuntu is probably the quickest way to test it... and it pretty much just works ;) use the ubuntu alternate install cd though since it has the option to install an ltsp server.
| |
| 20:44 | <ball> I think their "alternate" CD includes LTSP
| |
| 20:44 | * ball nods | |
| 20:44 | <beer30> jinx
| |
| 20:48 | <ball> Hmm... don't think I have any CD burning software.
| |
| 20:51 | <beer30> what OS?
| |
| 20:51 | * ball looks around the room | |
| 20:52 | <ball> Ubuntu (desktop) or MS Windows
| |
| 20:52 | Selveste1 has quit IRC | |
| 20:52 | <ball> ...have to be something pretty straightforward.
| |
| 20:53 | cdrecord?
| |
| 20:53 | <beer30> Ubuntu should have something... but I don't use it. M$, of course has lots... but I perfer... umm.... ImgBurn.
| |
| 20:53 | <ball> Come to think of it, I may also be able to boot NetBSD from a USB flash stick.
| |
| 20:53 | <Lns> ball, nautilus (gnome) has an integrated cd burn app
| |
| 20:53 | <ball> Lns: can that burn an ISO?
| |
| 20:53 | <Lns> right-click on ISO and select "Burn to CD"
| |
| 20:53 | or "Burn Image to CD" i think it is
| |
| 20:53 | <ball> Lns: Excellent, I'll try that now.
| |
| 20:53 | Thanks!
| |
| 20:53 | <beer30> ubuntu is cool like that ;)
| |
| 20:53 | <Lns> np
| |
| 20:55 | beer30, Ubuntu definitely has some talent in the usability department =)
| |
| 20:55 | <ball> I've been impressed with Ubuntu. It's the first Linux that I could think about putting in front of civilians
| |
| 20:55 | <Lns> heh, 'civilians'
| |
| 20:55 | <beer30> lol... ya, I think that is their motto... linux for civies
| |
| 20:55 | <Lns> LTSP works very well on it, and gets better all the time (along w/the other distros of course as well)
| |
| 20:56 | <beer30> ya, I was impressed by ubu 9.04 when it prompted me to install missing software... I think it was flash, and it actually installed it the "ubuntu way"...
| |
| 20:56 | Jorophose has joined #ltsp | |
| 20:57 | <Lns> well it inherits a lot of standardized methodology from debian, for sure
| |
| 20:58 | <Jorophose> not so much LTSP, but more thin clients in general... wasn't sure where else to ask. Is it possible to make the clients run their own copies of Linux, XOrg, and their own DE, and then run everything else on the server? I'm aiming for as seamless as possible, though, so I can't make the users log in to the other computer and launch apps, but I'm willing to modifiy launchers to do that...
| |
| 20:58 | * ball read that as "standardized mythology" on first pass. | |
| 20:59 | <beer30> lol @ ball
| |
| 20:59 | Selveste1 has joined #ltsp | |
| 20:59 | <Lns> heh
| |
| 20:59 | <ball> Jorophose: I was wondering earlier today whether I could run the wm on the terminal, but I wouldn't want a DE and things.
| |
| 21:00 | ...that would sort of miss the point I think.
| |
| 21:00 | <Lns> Jorophose, you can run things like that w/localapps
| |
| 21:00 | <beer30> @Jorophose if the clients ran their own stuff, that won't make them very thin... ;)
| |
| 21:00 | <Jorophose> ball: true, I meant something light like LXDE or xfce
| |
| 21:00 | <ball> Xfce != light
| |
| 21:00 | <Jorophose> haha, true, maybe I'm just overestimating the clients
| |
| 21:00 | <ball> No idea what LXDE is
| |
| 21:00 | <Jorophose> yeah, it has become more bloated =/
| |
| 21:00 | <Lns> Jorophose, what kind of power are you talking about on the clients?
| |
| 21:01 | <Jorophose> currently I'm working with Pentium 2s in the 450MHz-500MHz range, with 192MB to 384MB of RAM
| |
| 21:01 | <Lns> hmm...the 384mb ones *might* be ok to do it with
| |
| 21:01 | <Jorophose> powerful enough to be stand-alone, but browsers are really pig now.
| |
| 21:01 | <Lns> but that's a unique setup
| |
| 21:02 | yeah - they're hogs on the server too ;)
| |
| 21:02 | specially with things like flash (or anything else adobe ;) )
| |
| 21:02 | <beer30> you might want to look into ltsp fat clients ;)
| |
| 21:02 | <Jorophose> haha yeah, but I might be buying a Phenom II X4 920 for myself, so I can take most of the bloat
| |
| 21:02 | <beer30> http://www.nubae.com/creating-a-low-fat-client-environment-for-ltsp
| |
| 21:03 | <Jorophose> it's when I see stuff like this: http://www.norhtec.com/products/mctc/index.html it makes me wonder why all the power for nothing
| |
| 21:03 | * ball fires up rtorrent | |
| 21:03 | <Jorophose> but then again, I guess it's there so that you can have a working OS without the server
| |
| 21:03 | <ball> Jorophose: I'd rather have a matched pair of Shanghais
| |
| 21:03 | <Jorophose> yeah but I'm just a poor student ;P
| |
| 21:04 | I don't even know if I should go 920 or scale back to an X3 710 (the X4 920, stupidly enough, is the same price as the X3 720. Exacty same models except the X4 has 4 cores, and the X3 has unlocked multipliers)
| |
| 21:04 | <ball> Jorophose: Me too, which is why I can't buy a matched pair of Shanghais
| |
| 21:04 | Selveste1 has quit IRC | |
| 21:04 | <Jorophose> haha, but we can dream
| |

| 21:05 | <ball> If I had the money for a new server, I'd get some repairs done on my house.
| |
| 21:05 | ...or pay off some debt.
| |
| 21:05 | * ball shrugs | |
| 21:05 | <ball> Anyway, the ltsp stuff I'm tinkering with is mostly for someone else
| |
| 21:06 | ...and they have a dual-core Xeon box now.
| |
| 21:06 | ...with RAID and RAM and things.
| |
| 21:06 | FGXR6 has quit IRC | |
| 21:07 | <ball> ...I'm thinking of ltsp to replace MS Windows on the desktop. I recognize that we'll have to beef up the server a bit, but that's okay.
| |
| 21:08 | <Lns> ball, what kind of environment?
| |
| 21:08 | <Jorophose> oo, I was thinking that too. I've got two old computers, one runs linux, the other runs windows 2000, and both are starting to show their age. I was hoping through a kind of fat/thin client I could make them last longer
| |
| 21:08 | or were you thinking of something different?
| |
| 21:10 | <ball> Lns: a small office. We've pretty much standardized on SeaMonkey (Internet suite) and OpenOffice.org (Office suite) and the GIMP (bitmapped graphics). There are a few nasties out there still, but I'm tooling up.
| |
| 21:10 | <Lns> nice.
| |
| 21:10 | I run LTSP in my office too (just 2 clients), Ubuntu 8.04
| |
| 21:10 | and some schools in my area too
| |
| 21:10 | <Jorophose> ball: I've thought about pushing for thin clients in the office I work in. but they only recently bought a whole bunch of vostro desktops, so it would be a bit of a waste.
| |
| 21:11 | Lns: thin clients in schools are definately a great idea =O, it's just too bad the schools are often crooked with budgets =/
| |
| 21:11 | <ball> Jorophose: We have one new workstation. The others are at the end of their Windows lives, but that could be the beginning of a beautiful ltsp existance.
| |
| 21:11 | <Jorophose> ball: definately, I'd go for it if I were you.
| |
| 21:11 | <ball> ...until they die and are replaced by something solid state.
| |
| 21:12 | <Lns> Jorophose, that's the beauty - ltsp saves them money
| |
| 21:12 | <ball> Printing is an obstacle, but I'll work on that.
| |
| 21:12 | <Jorophose> I've always wanted something purely solid-state and netbooting
| |
| 21:12 | it would be cool to have
| |
| 21:12 | <ball> Jorophose: I have something like that, but have yet to tinker with it much.
| |
| 21:12 | <Jorophose> doesn't printing work fine if it's connected to the server?
| |
| 21:13 | <Lns> Even if you did fat client setups, you get the benefit of centralized administration
| |
| 21:13 | <ball> Jorophose: The office printer (colour laser printer) silently discards PostScript jobs. Unfortunately the Linux driver sends PostScript jobs and I don't know of a way to ask it to send PCL6 instead.
| |
| 21:13 | <Jorophose> that's true, it's easier to keep everything up to date
| |
| 21:14 | ball: oh, so this is printer-specific? does it work with normal linux desktops though?
| |
| 21:14 | <ball> Jorophose: no.
| |
| 21:14 | <Jorophose> oh, that sucks. I'm so glad I've just got a samsung laser printer at home. samsung is love <3
| |
| 21:15 | <ball> Not being able to print was a show-stopper during my first, very short, Linux trial.
| |
| 21:15 | "If we can't print, then we can't run Linux".
| |
| 21:15 | <Jorophose> what kind of printer? what about using silly hacks?
| |
| 21:15 | <Lns> I don't ever think I've seen a printer (besides those crappy 'winprinters') that didn't work with Linux
| |
| 21:16 | <ball> This definitely isn't a Winprinter
| |
| 21:16 | <Jorophose> Lns: I had an HP "winprinter" that worked great under linux
| |
| 21:16 | <Lns> at least on a 'standard printing' basis
| |
| 21:16 | <Jorophose> is it a lexmark?
| |
| 21:16 | <ball> I forget what it is now, and the office is 130 miles away.
| |
| 21:16 | <Jorophose> mm
| |
| 21:16 | <ball> Some fancy network-attached colour laser printer.
| |
| 21:16 | <Lns> well it's a long drive, you better get headed out ;)
| |
| 21:16 | <Jorophose> do you guys know anyone who makes innexpensive thin clients?
| |
| 21:16 | the cheapest I've found is NorhTec, but it's still 100USD.
| |
| 21:17 | <ball> Jorophose: I found some on the Web today
| |
| 21:17 | <Lns> Jorophose, www.disklessworkstations.com
| |
| 21:17 | <ball> Ah, the ones I was looking at were about US$ 300 +ehft
| |
| 21:17 | <Jorophose> eh, that's pretty pricey
| |
| 21:17 | <beer30> asus has eee boxes now... complete with wireless and 160gb hdd :D
| |
| 21:17 | <ball> ...I could buy a desktop PC for US$ 400, but the TCO would be much higher.
| |
| 21:17 | <Jorophose> is that normal for thin clients?
| |
| 21:17 | still, with a desktop you can do so much more =/
| |
| 21:18 | F-GT has joined #ltsp | |
| 21:18 | <beer30> asus b202's are about $280 and come with some cheesy linux os on the hard drive... but easily wiped out ;)
| |
| 21:19 | <ball> Jorophose: video editing springs to mind. Apart from that a terminal should be able to keep up.
| |
| 21:19 | <Lns> Jorophose, also http://www.thesymbiont.com/index.php?option=com_content&task=blogcategory&id=80&Itemid=109
| |
| 21:19 | there's other (cheaper) ones out there, but you get what you pay for..
| |
| 21:19 | you need to look at what kind of CPU & chipset (video included) you get with it
| |
| 21:19 | <ball> beer30: if it has a hard disk, it's not thin ;-)
| |
| 21:19 | <beer30> :P
| |
| 21:20 | <ball> I should just pick up a fleet of refurbished VT-220s ;-)
| |
| 21:20 | <Lns> beer30, wow the asus b202s look nice for a tc
| |
| 21:20 | <beer30> ya, but it's cheaper than most others... and you can always run firefox off the hard drive (among other apps) and still be ltsp.
| |
| 21:20 | <Jorophose> what about ARM on the client and x86 on the server
| |
| 21:20 | <Lns> beer30, easier to use localapps to run FF than from the hdd
| |
| 21:20 | <beer30> Lns, ya and they even come with a mounting bracket so you can attach them to the back of an lcd... plus they have dvi :D
| |
| 21:20 | artista has quit IRC | |
| 21:20 | <Lns> wow
| |
| 21:21 | wonder how much power they suck down
| |
| 21:21 | <ball> Jorophose: Why would that be a problem?
| |
| 21:22 | artista has joined #ltsp | |
| 21:22 | <beer30> lns is green ;)
| |
| 21:23 | <Jorophose> incompatible binaries
| |
| 21:23 | esp. for fatclients with ltsp?
| |
| 21:23 | <ball> Jorophose: with an X terminal that would be a non-issue.
| |
| 21:23 | <Jorophose> hmm, true.
| |
| 21:23 | <ball> ...also for LTSP?
| |
| 21:24 | <Lns> beer30, well i do work for schools. we have budget cuts you know. ;)
| |
| 21:24 | <Jorophose> nvm ball
| |
| 21:24 | it's too late, I should probably go to bed ;p
| |
| 21:24 | <ball> Until recently I ran X servers on PowerPC gear and apps on amd64
| |
| 21:24 | ...and SPARC, and i386...
| |
| 21:24 | <Jorophose> but were any programs being run locally? or all executed on server?
| |
| 21:24 | <ball> s/apps/clients/
| |
| 21:24 | <Lns> Jorophose, the ltsp-build-client has an --arch (i386, amd64, etc) switch
| |
| 21:24 | <beer30> ya, I hear ya.... nothing wrong with that
| |
| 21:24 | <ball> Jorophose: a mixture
| |
| 21:25 | <Jorophose> Lns: so you can say like i386+AMD64+ARM for example?
| |
| 21:25 | and each different arch gets its binaries?
| |
| 21:25 | <Lns> Jorophose, sure, at least the first 2
| |
| 21:25 | <Jorophose> hmm
| |
| 21:26 | <Lns> might wanna ask ogra (when he's on) about arm
| |
| 21:26 | <ball> On LTSP, wouldn't there be a text file somewhere with a list of MAC addresses and details of which image to feed them?
| |
| 21:26 | <Lns> plenty of people have amd64 ltsp servers and i386 clients
| |
| 21:26 | <Jorophose> ball: that would make sense too
| |
| 21:26 | <Lns> dhcpd.conf
| |
| 21:26 | <ball> Lns: there you go.
| |
| 21:27 | <Jorophose> ok, now somebody is jumping at me trying to get me to play mario kart. a good night to you, gentlemen (women?).
| |
| 21:27 | Jorophose has left #ltsp | |
| 21:28 | <Lns> heh
| |
| 21:28 | the asus b202 kinda looks like a wii
| |
| 21:28 | <beer30> lol... ya, but probably more powerful.
| |
| 21:30 | * Lns wonders if anyone has tried the b202 on ltsp | |
| 21:30 | <Lns> with any dist
| |
| 21:30 | <beer30> me
| |
| 21:30 | w/ ubuntu
| |
| 21:30 | it works pretty good.
| |
| 21:31 | <ball> That's damn shiny.
| |
| 21:31 | <beer30> the intel graphics are nothing to write home about though.... they have a b206 which has ati radeon though... and hdmi! ;) I have one of those too... but haven't tested it with ltsp yet.
| |
| 21:31 | <ball> ...I wonder if it'll boot without a hard disk.
| |
| 21:32 | <beer30> ya, I had to yank the hard drive out of the b206 'cause it kept wanting to boot to windows... that version has xp home and some special partition that by passes the bios and boots directly into windows... pita!
| |
| 21:33 | <Lns> gross
| |
| 21:33 | <beer30> lol... ya tell me about it.
| |
| 21:33 | <ball> That disk would see "dd" very quickly
| |
| 21:33 | <beer30> lol
| |
| 21:34 | Sarten-X has quit IRC | |
| 21:34 | <beer30> ya, I proably need to give it the axe. I felt pity on it though.
| |
| 21:35 | I did wipe out that crappy linux that comes on the b202 though and installed Sabayon since it has compiz out of the box ;)
| |
| 21:37 | the desktop effects worked pretty well, but I think the radeon chip would do much better. the intel graphics are passable though.
| |
| 21:38 | <ball> Meh, compiz
| |
| 21:39 | <beer30> no likey?
| |
| 21:39 | <ball> I'm not a fan, but that's hardly surprising given my background.
| |
| 21:41 | <beer30> dos?
| |
| 21:41 | <ball> No, I predate DOS ;-)
| |
| 21:41 | <beer30> yikes!
| |
| 21:41 | ;)
| |
| 21:42 | dos is probably why I like Gentoo... command line!!!
| |
| 21:42 | <ball> ...but for the past ten years I've lived in NetBSD with Blackbox as the window manager.
| |
| 21:42 | ...so I flick between virtual desktops with one mouse click and no animation ;-)
| |
| 21:42 | <beer30> heh
| |
| 21:42 | <ball> *lightning* fast.
| |
| 21:44 | Come to think of it, we did that back on the Concurrent CP/M-86 machines. Keypress or two and we're instantly looking at a different virtual console. That was text-based, but on some of the systems graphics was there too.
| |
| 21:44 | ...and on the boxen I'm thinking of, we could have four people simultaniously running four different apps each.
| |
| 21:44 | <beer30> ya, fast is good. compiz has gotten waaaay better in the last year or so though. but I like blackbox too... first thing I do when I install a new Gentoo box is install blackbox since it compiles in like no time flat.
| |
| 21:45 | <ball> ...on a 12 MHz 80186
| |
| 21:45 | <beer30> wow, that was way ahead of its time.
| |
| 21:45 | <ball> beer30: compact too, about the size of a shoe box
| |
| 21:46 | preemptive multitasking, very smooth. It's no wonder MS Windows never really impressed me.
| |
| 21:48 | johnny has left #ltsp | |
| 21:48 | <ball> That b202 looks alright, but it may burn more power than what we have now.
| |
| 21:49 | <beer30> very well could. I don't know how to figure power consumption.
| |
| 21:50 | <ball> beer30: I measure it.
| |
| 21:50 | <beer30> for a living or as a hobby ;)
| |
| 21:52 | a test on hothardware.com shows the full load bing 22.3W...
| |
| 21:53 | <ball> beer30: at various times during my career, both.
| |
| 21:53 | <beer30> not sure how they did their test though... says "Please keep in mind that we were testing total system power consumption here at the outlet. In this test, we're showing you a ramp-up of power from idle on the desktop to full CPU load."
| |
| 21:53 | <ball> Hmm, I could run four Sun Ray terminals for that ;-)
| |
| 21:54 | <beer30> wow
| |
| 21:54 | <ball> (not including their screens)
| |
| 21:56 | maginot has joined #ltsp | |
| 21:56 | <maginot> good evening .. =)
| |
| 21:56 | <beer30> good evening
| |
| 21:57 | * beer30 is reading up on sunrays ball turned him on to | |
| 21:58 | <ball> beer30: Main thing that puts me off Sun Ray is that it requires closed software running on the application server.
| |
| 21:59 | <beer30> ya, I figured. but makes you think about all the power you could be wasting/saving....
| |
| 22:00 | <ball> Proportionally the display is likely to burn a lot more.
| |
| 22:00 | ...but I would like to see X terminals (or ltsp-compatible "thin clients") with similar power footprint.
| |
| 22:03 | <beer30> hopefully in the near future... 23W for a thin client appears to about common place... but I wonder how much the hdd uses.
| |
| 22:04 | <ball> 5-10 Watts
| |
| 22:05 | ...I should think.
| |
| 22:05 | ...though I haven't measured that recently
| |
| 22:05 | (perhaps less for a 2.5" drive)
| |
| 22:06 | <beer30> ya, that is what I was thinking.
| |
| 22:13 | <ball> Does ltsp use xdmcp?
| |
| 22:16 | <Lns> ball, beer30: the disklessworkstation 1220pxe thin client runs on 8-11W total
| |
| 22:17 | <beer30> that is pretty acceptable
| |
| 22:17 | <ball> Lns: very nice. The 1220 is one I was looking at with great interest.
| |
| 22:18 | ...earlier today.
| |
| 22:18 | <Lns> ball, i use one every day. love it.
| |
| 22:18 | <ball> Lns: I should probably evaluate one.
| |
| 22:18 | <beer30> only bummer is that it doesn't have dvi
| |
| 22:19 | <Lns> talk to can-o-spam (when he's in the channel) he owns dw along with some others
| |

| 22:19 | lupo2 has joined #ltsp | |
| 22:19 | <lupo2> hello
| |
| 22:20 | <beer30> I bought my first round of thin clients from them.... can't think of the model off hand right now, but they work well.
| |
| 22:20 | hi lupo2
| |
| 22:20 | <lupo2> im need information of stress test of AS400
| |
| 22:20 | <ball> lupo2: You need to be more specific
| |
| 22:20 | <lupo2> stress test
| |
| 22:20 | <ball> more specific
| |
| 22:21 | <lupo2> test aplication
| |
| 22:21 | <ball> ...or more bilingual.
| |
| 22:21 | <lupo2> whit 9999 user
| |
| 22:21 | <Lns> beer30, they better - the guys who make them also do ltsp development ;) they're pretty much the only 'certified' ltsp terminals out there
| |
| 22:21 | <ball> Ah, okay. What does that have to do with ltsp?
| |
| 22:21 | <Lns> not that others don't work very, very well as well, ..
| |
| 22:22 | <ball> Lns: is the certification procedure expensive?
| |
| 22:22 | <Lns> ball, no clue
| |
| 22:22 | <ball> ok
| |
| 22:23 | <lupo2> test aplication of as400 with 9999 users? how?
| |
| 22:23 | <ball> lupo2: If you don't know, you probably shouldn't be trying it.
| |
| 22:23 | <beer30> off the wall question... why whould anyone want to use etherboot/gpxe over plain pxe? eg ltsp term 1220 vs 1225?
| |
| 22:24 | * ball shrugs | |
| 22:25 | <ball> If PXE does what I want it to, I'll happily use that.
| |
| 22:25 | Etherboot should achieve the same result I think. No idea what gpxe is
| |
| 22:25 | <beer30> ya, that is how I see it. back when I setup our ltsp 4.2 server I messed around with etherboot, but I can't recall if it had any advantages.
| |
| 22:26 | <ball> Perhaps its easier to burn onto an EPROM <- wild guess
| |
| 22:27 | <Lns> gpxe is kind of liked gpl-pxe (pxe is owned by intel) iirc
| |
| 22:27 | etherboot is also open source i believe
| |
| 22:27 | <ball> okay, so they're all ways of getting a bootloader onto the terminal
| |
| 22:27 | ...which can then fetch the kernel?
| |
| 22:27 | ...or can fetch something that can fetch the kernel ;-)
| |
| 22:28 | <Lns> an initramfs and kernel iirc
| |
| 22:28 | <ball> Ah, that initramfs isn't in the kernel?
| |
| 22:29 | <Lns> pxe = dhcp, tftp kernel, ..yes, initramfs is created by kernel i think..its been a while since i read about it
| |
| 22:29 | <ball> ok
| |
| 22:29 | <Lns> kernel executes everything (hw detection, setup of filesystem, etc.) and launches X server to connect to an app server on the network (a lot of times the same ltsp server)
| |
| 22:30 | <ball> I'll probably be back later. I would rather stop here and talk and learn, but I have some things to do.
| |
| 22:30 | <Lns> err, rather ldm, to choose app server and launch x server w/that
| |
| 22:30 | cheers =)
| |
| 22:30 | <beer30> L8r!
| |
| 22:30 | <ball> is ldm related to xdm?
| |
| 22:30 | <Lns> they're both display managers
| |
| 22:30 | ;)
| |
| 22:30 | <beer30> ldm = ltsp display manager
| |
| 22:31 | ldm provides ssh security
| |
| 22:32 | <ball> Hmm... okay.
| |
| 22:32 | back later (I hope)
| |
| 22:32 | ball has quit IRC | |
| 22:36 | * beer30 is going to try to intall Fedora 11 now | |
| 22:36 | <beer30> doh! I hate typos!
| |
| 22:37 | RobertBerger has joined #ltsp | |
| 22:39 | <lupo2> test aplication of as400 with 9999 users? how?
| |
| 22:40 | <Lns> lupo2, that isn't an ltsp question
| |
| 22:42 | <lupo2> mmm ok
| |
| 22:42 | lupo2 has left #ltsp | |
| 22:42 | RobertBerger2 has joined #ltsp | |
| 22:51 | ball has joined #ltsp | |
| 22:51 | <ball> Quick question, does ltsp run an XDMCP Chooser on the thin client at boot?
| |
| 22:52 | (can it?)
| |
| 22:52 | <jammcq> that's what LDM is for. IT's XDMCP. it uses ssh, and it can have a list of servers to choose from
| |
| 22:52 | err
| |
| 22:52 | it's NOT xdmcp
| |
| 22:53 | xdmcp has no encryption, so no security
| |
| 22:55 | RobertBerger1 has quit IRC | |
| 22:56 | <ball> That sounds like a point in ldm's favour then.
| |
| 22:56 | ;-)
| |
| 22:57 | <jammcq> LDM is more like a gui front end for SSH. It asks for a user-id and password, then launches the session on the server. It supports themes, and it sets up some ssh tunnels for handling audio and local devices
| |
| 22:58 | <ball> jammcq: does that mean that the server only needs to expose port 22?
| |
| 22:58 | <jammcq> yeah, I think so
| |
| 22:58 | and NBD
| |
| 22:58 | I forget what port that runs on
| |
| 22:59 | <ball> Hmm... okay.
| |
