| 04:04 | <alibaba> alkisg: Hello, I was told you are an "gPXE guru". May I please you for a little help, please?
| |
| 04:04 | <alkisg> Heh I was typing a gpxe script here!!!!
| |
| 04:04 | OK let me type it and go ahead
| |
| 04:05 | Here's a gpxe script that can be used to boot LTSP clients with an external, unmodifiable DHCP server:
| |
| 04:05 | dhcp net0
| |
| 04:05 | # Put the LTSP server IP in the following line
| |
| 04:05 | set next-server 10.160.31.10
| |
| 04:05 | kernel tftp://${next-server}/ltsp/i386/vmlinuz ro initrd=initrd.img nbdroot=${next-server}:2000
| |
| 04:05 | initrd tftp://${next-server}/ltsp/i386/initrd.img
| |
| 04:05 | boot vmlinuz
| |
| 04:05 | To use it, just go to http://rom-o-matic.net/gpxe/gpxe-1.0.0/contrib/rom-o-matic/build.php and put it in the [Embedded script] box.
| |
| 04:06 | alibaba: ok done, shoot!
| |
| 04:06 | (I was writing that to find it in the logs when I need it)
| |
| 04:07 | <alibaba> alkisg: I have an very old AXUS TC200 series device I want to reuse. I got gPXE working, but I always must press Ctrl-B, wait on the prompt for ~10 seconds, then enter autoboot. Without that, it doesn't get DHCP working.
| |
| 04:07 | <alkisg> Woah
| |
| 04:07 | Which gpxe version is that?
| |
| 04:08 | <alibaba> Current one, I got it a few days ago from rom-o-matic, and with kindly help i could install it on a CF card.
| |
| 04:08 | <alkisg> OK. First, I'd report the problem to #etherboot
| |
| 04:08 | Then I'd try the method that I said above,
| |
| 04:09 | but putting "autoboot" in the embedded script instead of my script above
| |
| 04:09 | In essense it's like pressing ctrl+b and typing autoboot yourself...
| |
| 04:10 | (ehm, some explanation: the rom-o-matic site allows you to embed some commands in the gpxe.krn/dsk/iso/usb you download...)
| |
| 04:10 | <alibaba> Do you have any idea what can cause this problem at all?
| |
| 04:11 | <alkisg> I'm guessing some BIOS initialization problems, but you'd need to ask a gpxe coder for details
| |
| 04:12 | Join #etherboot in IRC and ask there...
| |
| 04:12 | <alibaba> thank you.
| |
| 04:12 | <alkisg> alibaba: if it's just that terminal, you can make a script that completely bypasses dhcp..
| |
| 04:13 | (or, that waits 10 seconds and runs autoboot afterwards)
| |
| 04:13 | <alibaba> Yes, only this one.
| |
| 04:14 | <alkisg> Try embedding a script then, it's the easiest method
| |
| 04:14 | <alibaba> I don't want to bother Marty Connor again. He himself helped me to get this CF card booting at all.
| |
| 04:15 | Does gPXE automatically search and execute a script file?
| |
| 04:15 | <alkisg> OK, just go to the rom-o-matic site...
| |
| 04:15 | See the link I posted above.
| |
| 04:16 | (11:01:54 πμ) alkisg: To use it, just go to http://rom-o-matic.net/gpxe/gpxe-1.0.0/contrib/rom-o-matic/build.php and put it in the [Embedded script] box.
| |
| 04:17 | <alibaba> I'll do so... Which commands does it uinderstand?
| |
| 04:17 | <alkisg> Type `help` in the gpxe prompt to get the list
| |
| 04:17 | <alibaba> ok. Thank you.
| |
| 04:17 | <alkisg> (i.e. `autoboot` etc...)
| |
| 04:17 | You're welcome

| 09:15 | <infro> hello
| |
| 09:15 | <sbalneav> hello
| |
| 09:15 | <infro> I have another problem with my ltsp
| |
| 09:15 | most client can access with same username
| |
| 09:15 | when I disable it?
| |
| 09:17 | it's possible?
| |
| 09:17 | <sbalneav> Not sure what you mean.
| |
| 09:18 | Do you mean you want to stop people from logging in multiple times with the same username?
| |
| 09:18 | <infro> yes
| |
| 09:18 | in this moment
| |
| 09:19 | if I have 3 client up
| |
| 09:19 | I can login with same username
| |
| 09:19 | <sbalneav> right
| |
| 09:19 | so, don't do that :)
| |
| 09:19 | <infro> simultaneously
| |
| 09:20 | hahahah :D
| |
| 09:20 | ok
| |
| 09:20 | but in one university this is the problem
| |
| 09:20 | epaphus has joined #ltsp | |
| 09:20 | <sbalneav> That's not really an LTSP problem.
| |
| 09:21 | If you'd like to restrict that, then set up an Xsession.d script that detects multiple logins, and boot the person off.
| |
| 09:22 | You can set LDM_LIMIT_ONE_SESSION_PROMPT
| |
| 09:22 | to true
| |
| 09:22 | but that only helps if you only have one server.
| |
| 09:22 | <cyberorg> sbalneav, LDM_LIMIT_ONE_SESSION?
| |
| 09:23 | or is it _PROMPT now?
| |
| 09:23 | <infro> I have one server
| |
| 09:23 | sbalneav: it's on lts.conf?
| |
| 09:24 | <sbalneav> Sorry, that's the prompt
| |
| 09:24 | it's LDM_LIMIT_ONE_SESSION
| |
| 09:24 | It's not in the docs, I'll have to add it.
| |
| 09:25 | infro: yes, that's where everyhting gets set on thin clients.
| |
| 09:25 | <cyberorg> i think both are required, just read ldm-trunk/rc.d/S15-userLoginCheck
| |
| 09:26 | <sbalneav> That's what I'm doing.
| |
| 09:27 | No.
| |
| 09:27 | LDM_LIMIT_ONE_SESSION_PROMPT isn't required
| |
| 09:27 | if it's not set, there's a default message.
| |
| 09:28 | <cyberorg> ok
| |
| 09:30 | <infro> I test it
| |
| 09:30 | it's not work :(
| |
| 09:37 | cyberorg: I have find S15-userLoginChect
| |
| 09:37 | I copy in in etc/rc.d/ and update the image?
| |
| 09:38 | <cyberorg> infro, no it will already be in right place where ldm expects it, just change lts.conf adding those variables to True
| |
| 09:40 | <infro> I have only add True at the variable, but not work
| |
| 09:40 | Do can I update the image?
| |
| 09:49 | pths has quit IRC | |
| 09:54 | <sbalneav> infro: Does your lts.conf sit in the tftp area? Or in the /opt/ltsp area? If the latter, then yes, you'll have to update the image.
| |
| 09:55 | <infro> tftp
| |

| 12:19 | <anivair> does anyone know if dicklessworkstations.com has any thin clients that are POE compatible? it's be great not to have to run power cords here.
| |
| 12:20 | <Lns> anivair: if you wait around maybe CAN-O-SPAM will show up, he works there
| |
| 12:21 | <anivair> coolness. I'll hang for a bit
| |
| 12:21 | if I end up having to go, i'll ask the list
| |
| 12:22 | <Lns> anivair: did you look on their website? I'd think that it would tell you as well ;)
| |
| 12:23 | <anivair> I looked. nothing says it specifically, but Im thinking it might be me (I've never really looked for it before)
| |
| 12:24 | <Lns> what kind of environment are you in that you don't want power run to the terminals?
| |
| 12:25 | infro has quit IRC | |
| 12:30 | <anivair> we're in a call center. Mostly I just want to cut down on as many cables as I can and if I can get it down to just one net/power cable, that would be easier
| |
| 12:30 | also, my switches are more reliable than the power outlets here
| |
| 12:31 | jammcq has joined #ltsp | |
| 12:40 | <johnny> does POE really offer enough power for those?
| |
| 12:40 | is it even possible?
| |
| 12:42 | it doesn't sound possible..
| |
| 12:43 | vvinet has joined #ltsp | |
| 12:54 | <Lns> johnny: there are thin clients w/PoE
| |
| 12:58 | <anivair> I'm sure it's possible. I power a lot of stuff on a POE switch.
| |
| 12:59 | <johnny> Lns, i wonder what the max is..
| |
| 12:59 | <jammcq> the switch docs will tell you how much power can be delivered
| |
| 12:59 | with that, it just becomes a simple math problem
| |
| 13:01 | <Lns> Too bad LCDs don't have the extra AC input that the old PC power supplies used to have..
| |
| 13:01 | Anyone remember those?

| 13:09 | <johnny> Lns, i do..
| |
| 13:09 | never used it tho..
| |
| 13:10 | <Lns> Would seem logical to, now that LCDs and TCs are such low power, to have a single power cord for them
| |
| 13:12 | <vagrantc> power-over-ethernet sounds pretty ideal
| |
| 13:14 | <alkisg> There are cords that can at the end of the LCD power cord and before the LCD itself, and "fork" the current to the TC...
| |
| 13:15 | Some speakers have those
| |
| 13:15 | <Lns> stgraber: http://pastebin.com/K7QAtgYH - just caught this while upgrading my lucid chroot.. is this an issue?
| |
| 13:15 | alkisg: hmmmmm
| |

| 13:19 | ogra_cmpc has quit IRC | |
| 13:19 | <Lns> those would work really well, especially if the client was vesa mounted and thus very close to the lcd

| 13:26 | Remaille has joined #ltsp | |
| 13:27 | <Lns> How exactly does LOCAL_APPS_MENU_ITEMS work under the hood? Does it watch out for those local processes?
| |
| 13:27 | For example, how would it know to run openoffice writer locally if you hvae LOCAL_APPS_MENU_ITEMS = ooffice -- vs -- LOCAL_APPS_MENU_ITEMS = oowriter ?
| |
| 13:28 | (should be ooffice -writer in the first one)
| |
| 13:29 | <sbalneav> I believe it's just doing its work with .desktop files
| |
| 13:30 | No "process" magic.
| |
| 13:31 | <alkisg> So it should be openoffice.org-writer, because it is openoffice.org-writer.desktop
| |
| 13:31 | (i.e. it looks at the desktop file name afaik)
| |
| 13:32 | <Lns> oh! ok
| |
| 13:32 | thx guys

| 13:40 | <Lns> i'm impressed at how well some of this localapp stuff performs
| |
| 13:40 | OOo doesn't break a sweat
| |
| 13:40 | on an atom 1.6 (course it's 4 cores lol).. need to grab some clients from the schools to see how well they'll perform next school year
| |
| 13:42 | <Blinny> I'm very excited about the prospects of moving to Lucid.
| |
| 13:43 | My hardy boxes have been gems, but OO has shown its age. PPAs don't quite work for me with some files.
| |
| 13:43 | leio_ is now known as leio | |
| 13:51 | <Lns> Blinny: i'm in your boat too. Testing lucid from hardy. I'll be upgrading from i386 -> amd64 server, too.
| |
| 13:52 | besides the cosmetics in the themes and stuff, i'm really really liking lucid's performance
