| 04:55 | <map7_> I'm setting up an ubuntu machine as a LTSP server should I be using NBD or NFS?
| |
| 05:00 | I'm currently getting this error on my LTSP clients 'mount: mounting /dev/nbd0 on /rofs failed: Input/output error'
| |
| 05:00 | has anyone experienced this?
| |
| 05:17 | <alkisg> Ubuntu is using NBD by default, so you should prefer that unless you have specific needs
| |
| 05:18 | map7_: That error means that the client has problems reading the nbd mounted disk. Which ubuntu version are you using?
| |
| 05:18 | E.g. if you exported a directory instead of /opt/ltsp/images/i386.img, then you'd get this error.
| |
| 05:20 | <map7_> alkisg, I've just been playing around with the nbdport variable on the kernel boot line and got it to work! So it looks like the client was looking on the wrong port number
| |
| 05:23 | alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Quit: Leaving.) | |
| 06:19 | <map7_> Will the mythbuntu switch on ltsp-build-client work with nbd?
| |
| 06:27 | freedomrun has joined IRC (freedomrun!~quassel@BSN-176-166-151.dial-up.dsl.siol.net) | |
| 06:53 | <map7_> Looks like the problem is when I start using 'mythbuntu' switches on the ltsp-build-client command
| |
| 06:58 | VectorX has joined IRC (VectorX!knight@unaffiliated/vectorx) | |
| 06:59 | <VectorX> is there such a setup where when you drag windows apps around in the gui on thin clients there is no lag ? or will there always be a lag noticed ?
| |
| 07:00 | <map7_> VectorX, check out crossover linux, I use it for thin clients and it works well for most apps
| |
| 07:01 | <VectorX> the main os is ubuntu, so how would this help with the speed ?
| |
| 07:05 | <map7_> i thought you were asking about 'microsoft windows apps' running within linux
| |
| 07:06 | <VectorX> im sorry my bad wrong wording, i mean drag apps in the gui so you dont notice a lag
| |
| 07:06 | on tha thin client, ubuntu based
| |
| 07:07 | <map7_> first make sure you are using 2d only, not compriz or any effects
| |
| 07:07 | pick a lighter theme
| |
| 07:07 | upgrade your network to 1Gbit
| |
| 07:07 | <VectorX> net is 1gbit but client cards are 100
| |
| 07:07 | <map7_> use more power graphics cards on thin clients
| |
| 07:08 | i don't have any lag at work, but my thin clients have 1Gbit and an intel on-board GPU (Intel 510MO Atom motherboard)
| |
| 07:09 | It could be the number of clients you have and the amount of traffic
| |
| 07:09 | <VectorX> im just testing 2
| |
| 07:09 | but pemtium 2gz 512ram, basic onboard gfx
| |
| 07:10 | <map7_> it could be the graphics card, I remember having the same issue with older thin clients
| |
| 07:10 | check that it's 2d
| |
| 07:11 | <VectorX> although let me try a much faster system and see if there is a differece

| 12:33 | <muppis> alkisg, you should update gPXE in win-loader. ;)
| |
| 12:35 | <alkisg> muppis: why 1.0 doesn't have a driver for your card?
| |
| 12:35 | <muppis> Nop.e.
| |
| 12:35 | <alkisg> 1.0.1 didn't work with proxydhcp, and ipxe had some other bugs, so I was waiting for ipxe to have a release
| |
| 12:35 | <muppis> nForce 2
| |
| 12:35 | <alkisg> And ipxe has a driver for that?
| |
| 12:35 | You can just copy ipxe.lkrn and override that file
| |
| 12:35 | Here's a freshly compiled one:
| |
| 12:36 | http://people.ubuntu.com/~alkisg/tmp/ipxe.lkrn
| |
| 12:36 | <muppis> Grabbed new gpxe from rom-o-matic and it worked.
| |
| 12:36 | <alkisg> Nice
| |
| 12:37 | Now if anyone could write a wiki page about ipxe + win32-loader... :)

| 14:44 | <piet> hi folks, is there a way to change the hostname via lts.conf. Read about an undocumented possibility to do that . . .
| |
| 14:44 | <alkisg> HOSTNAME=XXX
| |
| 14:45 | Under [mac:address] sections
| |
| 14:45 | <||cw> wouldn't that be better set via dhcp?
| |
| 14:45 | so it gets dns integrated?
| |
| 14:45 | <piet> I want the original dns name instead of the <ltsp5> etc.
| |
| 14:46 | how to do that?
| |
| 14:46 | <||cw> so your dhcp server doens't kow the mac is supposed to have that dns name?
| |
| 14:47 | I guess if it's separate and you have mappings for mac to ip and dns to ip then the lts.conf is the place to do it
| |
| 14:47 | <piet> I didnt get the point . . .
| |
| 14:48 | in dhcp I have . . .
| |
| 14:48 | static ips via mac-addresses
| |
| 14:48 | and I want the ltsp to take those dns names
| |
| 14:49 | <||cw> normally, as in not ltsp, if you want a certain mac address to get a certain hostname (except with windows) you put the host name mapping in your dhcp server
| |
| 14:49 | <piet> what would be the best way to do that
| |
| 14:49 | <alkisg> If your dhcp/dns servers are configured correctly, it's done automatically
| |
| 14:50 | <piet> do You want to see an example?
| |
| 14:50 | <alkisg> Is your ltsp server the only dhcp server in your network?
| |
| 14:50 | <piet> Yes
| |
| 14:50 | * ||cw <3 dnsmasq | |
| 14:50 | * alkisg too :) | |
| 14:51 | <||cw> makes these things so simple
| |
| 14:51 | <alkisg> piet: edit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
| |
| 14:51 | Put "break=mount" there
| |
| 14:51 | Then do: cat /tmp/net-eth0.conf
| |
| 14:51 | You'll see the info the client gets from your dhcp server there
| |
| 14:51 | If you do see a correct HOSTNAME, then it's an ltsp problem
| |
| 14:51 | If you don't, it's a dhcp/dns configuration problem
| |
| 14:52 | dead_inside has joined IRC (dead_inside!~dead_insi@76.75.3.174) | |
| 14:52 | <piet> ok I try this immediately . . .
| |
| 14:52 | <alkisg> (break=mount will drop you to an initramfs prompt when the client boots)
| |
| 14:53 | <piet> and there I do the cat thing?
| |
| 14:53 | <||cw> alkisg: did you see my 3M touch driver solution?
| |
| 14:53 | <alkisg> ||cw: nope
| |
| 14:53 | <||cw> also I reported that X -configure issue to the X package
| |
| 14:54 | https://help.ubuntu.com/community/UbuntuLTSP/3MMicroTouchDriver
| |
| 14:54 | <alkisg> piet: did you put it in the same line as "quiet splash"?
| |
| 14:54 | <||cw> i put it on the wiki :)
| |
| 14:54 | <alkisg> piet: boot the client, you'll get a text prompt, run the command there
| |
| 14:54 | ||cw: let me read...
| |
| 14:55 | ||cw: very good! I think you'll be the ubuntultsp wiki maintainer for the next year... :D
| |
| 14:55 | <||cw> heh
| |
| 14:59 | <stgraber> hmm, I guess I'll need to convince vagrantc to tag 1.0 of ltsp-docs and upload that to Debian :)

| 16:29 | <piet> alkisg gave me a hint how to find out why I get a wrong hostname. This trick didnt work so I couldnt find out whos fault it is. DHCP or ltsp.
| |
| 16:30 | <alkisg> piet: put your pxelinux.cfg/default file to pastebin
| |
| 16:30 | !pastebin
| |
| 16:30 | <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.

| 16:33 | <piet> Because I have a section for every client in my lts.conf it wouldnt be a problem for me to set the hostname for every client. But for this I need the undocumented order to do that . . .
| |
| 16:34 | anybody who knows, whats going on?
| |
| 16:34 | <alkisg> piet: did you see my answer above?
| |
| 16:34 | <piet> this pastebin stuff?
| |
| 16:36 | Right now I feel a little disorientated I guess I didnt see Your answer . . .
| |
| 16:38 | ah you mean the pxelinux.cfg/default . . . wait
| |
| 16:38 | <alkisg> That's the file where I told you to put the break=mount parameter
| |
| 16:39 | <piet> yes Im on my way gimme some time . . .

| |
| 16:50 | What do You mean by <quiet splash>?
| |
| 16:50 | <alkisg> Read the file
| |
| 16:50 | Find those words in it
| |
| 16:51 | You were supposed to put "break=mount" in line 6, but you put it in line 13
| |
| 16:51 | <piet> ahhh, thank U
| |
| 16:52 | <alkisg> Don't worry about your english they're fine. Just read what people tell you many times and ask if you don't understand something.
| |
| 16:52 | I'm not a native english speaker either, I'm greek :)
| |
| 16:55 | <piet> @ alkisg: dont worry there are worst things ;-) I hope we 'll work it out -> I'll leave for the test . . .

| 17:27 | <tkteun> Hi, I recently started experimenting with LTSP for simple SDL games (like OpenTTD)
| |
| 17:28 | Now this spikes sometimes and this breaks gameplay
| |
| 17:29 | I've read the manual but somethings aren't really clear
| |
| 17:29 | Is it possible to configure client side channel bonding (prefferably LACP) in lts.conf?

| |
| 17:30 | <alkisg> piet: I'm not using dhcp3-server, so I don't know that file syntax
| |
| 17:31 | <mnevans> @alkisg, @stgraber, just to let you know, I revised the ltsp wiki page on setting up the AMD E-350 reflecting your help with that yesterday.
| |
| 17:31 | It is here: https://help.ubuntu.com/community/UbuntuLTSP/AMDE-350?highlight=%28\bCategoryLtsp\b%29
| |
| 17:31 | <alkisg> tkteun: no, you can't do bonding from lts.conf
| |
| 17:32 | <mnevans> To be specific: usb support at the localdev for a 64 bit client.
| |
| 17:32 | <alkisg> mnevans good work :)
| |
| 17:32 | <mnevans> Thanks again!
| |
| 17:32 | No, the work was all yours!
| |
| 17:32 | <tkteun> about half of my clients have 3 rtl81.. chips, the others usually just one
| |
| 17:32 | mnevans has left IRC (mnevans!~mnevans@zero.geol.umd.edu) | |
| 17:33 | <alkisg> tkteun: try running your game as a localapp, if your clients are good enough it'll run better
| |
| 17:33 | <tkteun> I tried it, but with 800MHz they're not up to it
| |
| 17:33 | even worse than 100Mbps on ltsp
| |
| 17:34 | <alkisg> I'm not sure if bonding on the client is worth the trouble... isn't it easy to upgrade them to gigabit?
| |
| 17:35 | <tkteun> Is it possible to share one image across all my clients or should I make one especially for these clients?
| |
| 17:35 | CV 860A 3R80: http://www.synertrontech.com/products/Embedded%20Boards/cv_860a.htm
| |
| 17:35 | <alkisg> You would setup bonding in the initramfs, before the image (assuming you're talking about nbd) is loaded
| |
| 17:36 | <piet> @alkisg: What Do You meant about setting the hostname explicitly in lts.conf?
| |
| 17:37 | <alkisg> piet: if a client has a mac address of 01:02:03:04:05:06, you put this in lts.conf:
| |
| 17:37 | [01:02:03:04:05:06]
| |
| 17:37 | HOSTNAME=pc01
| |
| 17:37 | And you'd need another such section for any other client
| |
| 17:37 | <tkteun> The settings from initramfs remain in the nbd image?
| |
| 17:37 | <alkisg> initramfs == initrd.img
| |
| 17:37 | nbd image == /opt/ltsp/images/i386.img
| |
| 17:37 | Unrelated
| |
| 17:37 | <piet> @alkisg: thanx a lot . . .
| |
| 17:40 | <alkisg> tkteun: the network is set up in the initramfs. After that, the connection must stay up at all times, no reconfiguration can be done. After that, the nbd image is mounted.
| |
| 17:41 | You did try LDM_DIRECTX=True, right?
| |
| 17:41 | <tkteun> yes, definitely
| |
| 17:41 | <alkisg> And also lowering the resolution or using 16 bit color depth helps
| |
| 17:41 | <tkteun> generally it's alright, but it stalls every 1~2 seconds
| |
| 17:42 | So the initramfs is also where ipconfig resides?
| |
| 17:42 | <alkisg> Yes, and udhcpc too
| |
| 17:43 | <tkteun> because I ran into a little bug in there too where ipconfig decides on which 1 of the ports it takes dhcp from
| |
| 17:44 | ending up in a kernel panic if there's no connection on the last interface
| |
| 17:44 | eth2 in my case
| |
| 17:44 | <alkisg> Which distro/version are you using?
| |
| 17:45 | <tkteun> debian on the ltsp server with another debian dhcp server

| 17:57 | <tkteun> I think I'll let pxelinux do the discrimination between clients and make changes in the initrd, at least for this dhcp issue
| |
| 17:58 | have you got any recommendations for documentation on this?
| |
| 17:59 | ||cw has left IRC (||cw!~chris@phpgroupware/cw, Remote host closed the connection) | |
| 18:02 | <alkisg> tkteun: you just need to put an "if" in the initramfs, no different images or whatsoever
| |
| 18:02 | If it's one of those special clients, do bonding
| |
| 18:03 | <vagrantc> initramfs tweaking?
| |
| 18:03 | <alkisg> But you'll need to dig into how to add stuff to the initramfs etc
| |
| 18:03 | He wants to do bonding in the clients
| |
| 18:03 | <vagrantc> bonding in the initramfs... whoah.
| |
| 18:03 | <alkisg> In some of them, that is
| |
| 18:03 | <vagrantc> a most unusual use case?

| 18:04 | <tkteun> sounds like an adventure :)
| |
| 18:04 | <alkisg> Yeah I tried to tell him it's usually easier to upgrade the clients to gigabit, but he has 2-3 ethernet port in his motherboards
| |
| 18:04 | Yes, it is an adventure :)
| |
| 18:04 | <vagrantc> an educational experience you'll learn from ... other than that, probably not worth the hassel :)
| |
| 18:04 | <tkteun> strange motherboards... no pcmcia but three 8139's
| |
| 18:05 | <alkisg> It would probably be easier to fix your lag problem though, if it's only once per 1-2 seconds
| |
| 18:05 | <tkteun> so, does anyone have any recommended reading for custom initrd-ltsp
| |
| 18:05 | <alkisg> Try man initramfs-tools
| |
| 18:06 | <tkteun> on my gigabit client the bandwidth spikes to 40MB/s when the others lag
| |
| 18:06 | <alkisg> Is that spike caused by the game?
| |
| 18:06 | <tkteun> think it's an sdl problem
| |
| 18:06 | <alkisg> Maybe you could change the code a bit so that it doesn't use network spikes but it causes more regulated traffic
| |
| 18:07 | <||cw> sdl over 100Mbit?
| |
| 18:07 | * ||cw shudders | |
| 18:07 | <tkteun> bubble breaker is more continuous
| |
| 18:07 | especially in the intro
| |
| 18:07 | <alkisg> And _that_ advanture would be worth the hussle, if it helps playing sdl games over 100mbps :D
| |
| 18:08 | <tkteun> but I must say it's amazing that vlc player and flash works quite good already
| |
| 18:09 | <||cw> those then to stream and constant rates, and most videos are only 1Mbps anyway
| |
| 18:09 | <alkisg> Vlc uses xvideo, i.e. 12 bpp resized on the client
| |
| 18:09 | So it's about 50 mbps for a normal divx
| |
| 18:09 | <||cw> still, stream
| |
| 18:09 | games burst
| |
| 18:10 | <alkisg> ||cw: the 1mbps stream is until the server, then it's normal X traffic, not compressed video
| |
| 18:10 | E.g. you can't watch a dvd with 100mbps, it requires 125 mbps
| |
| 18:10 | And if I remember well HD video is about 600mbps
| |
| 18:11 | <tkteun> the traffic is usually 7MiB/s with 11MiB/s spikes
| |
| 18:11 | <alkisg> That's bytes, not bits, right?
| |
| 18:11 | <tkteun> with youtube/vlc
| |
| 18:11 | <alkisg> Youtube is much different than vlc
| |
| 18:12 | Don't compare them
| |
| 18:12 | One uses xvideo, the other not
| |
| 18:12 | If you switch to fullscreen, flash uses more bandwidth, vlc not
| |
| 18:12 | The formula for xvideo is video width * video height * 12 bpp * frame rate
| |
| 18:12 | <tkteun> yeah, flash fullscreen is the devil
| |
| 18:12 | <alkisg> While for flash it's window width * window height * screen bpp * frame rate
| |
| 18:13 | (with video i mean the original video dimentions, independed of the size you're watching it in)
| |
| 18:13 | <tkteun> isn't it possible to limit that screen bpp to 12 then?
| |
| 18:13 | xorg.conf?
| |
| 18:13 | <alkisg> No
| |
| 18:13 | !flash
| |
| 18:13 | <ltsp> alkisg: flash: Yes, flash sucks. Make sure you have LDM_DIRECTX=True in your lts.conf file, or if it's just youtube you're after, try some flash replacing plugin like https://addons.mozilla.org/el/firefox/addon/161869/ (per user installation, gecko-mediaplayer is also needed).
| |
| 18:13 | <alkisg> Only with different youtube players that would use xvideo
| |
| 18:14 | <tkteun> still no html5 youtube
| |
| 18:15 | <alkisg> I haven't checked if html5 capable browsers use xvideo
| |
| 18:15 | It'd be very nice for ltsp if they did
| |
| 18:15 | <tkteun> but they would use some ffmpeg player
| |
| 18:16 | vlc/mplayer
| |
| 18:19 | Well thanks for the insights, I'll make sure to make a nice Guide when I succeed
| |
| 18:19 | see you later

| 18:59 | <markit> hi, anyone with the correct line to add in /etc/network/interfaces to direct traffic to squid transparently? Or, with the system correctly setup (I use shorewall), be able to "extract" the command to give to iptables?
| |
| 19:02 | <mmetzger> markit: You mean an IPTables Redirect?
| |
| 19:03 | <markit> mmetzger: something like (shoudl work, but yesterday did not) iptables -t nat -A PREROUTING -m owner ! --uid-owner proxy -p tcp --dport 80 -j REDIRECT --to-port 3128
| |
| 19:03 | I've 2 interfaces
| |
| 19:03 | I've enabled forwarding and nat, from fat clients and from server navigation is ok
| |
| 19:03 | I've also setup squid, and now I would like to use it as transparent proxy
| |
| 19:04 | with shorewall I'm able to do so
| |
| 19:04 | but would love avoid shorewall and just setup iptables directly
| |
| 19:04 | <mmetzger> And Squid is running on the same box as where you have the iptables rule?
| |
| 19:04 | <markit> yes
| |
| 19:04 | that's why I need ! --uid-owner
| |
| 19:04 | to avoid the "recursion"
| |
| 19:05 | <mmetzger> any other port blocking on the INPUT chain? (or at least, is 80 open?)
| |
| 19:05 | <markit> I ask just in case that someone already has the 3-4 rules needed to make ltsp work like I want
| |
| 19:05 | mmm with iptables "clean" I apply
| |
| 19:05 | echo 1 > /proc/sys/net/ipv4/ip_forward
| |
| 19:06 | iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
| |
| 19:06 | <mmetzger> I've set something up similar recently, but it's not quite the same deal
| |
| 19:06 | <markit> (eth0 is WAN)
| |
| 19:06 | and it works fine
| |
| 19:06 | but I know almost nothing about iptables (ok, shame on me)
| |
| 19:07 | btw, my ltsp server is on a pc that at the moment is used by one of my childre, so cant' directly experiment right now
| |
| 19:08 | <mmetzger> My setup doesn't use the --uid-owner piece as it's actually a completely separate firewall but I am redirecting port traffic for a few specific ports.
| |
| 19:09 | My main issues were the INPUT chain being open for the ports being accepted, and then remembering that REDIRECT only works locally.
| |
| 19:14 | <markit> I've the feeling I 've to stick with shorewall and the config I know works, and then study iptables working
| |
| 19:15 | <alkisg> If shorewall configures your iptables ok, why don't you just dump them and examine them?

| |
| 19:21 | markit: transparent proxy, that is
| |

| 19:23 | <markit> vagrantc: I have a shorewall setup that works

| 21:02 | <markit> that, except if I did something wrong, removed the comment in NO_COMP
| |
| 21:02 | <alkisg> It needs to put a comment, not remove it
| |
| 21:02 | <markit> ops, commented sorry
| |
| 21:02 | <alkisg> OK
| |
| 21:03 | <markit> system(%q[sed -i '/^NO_COMP.*/s/^/# /' /etc/ltsp/ltsp-update-image.conf])
| |
| 21:03 | <alkisg> What are your client specs?
| |
| 21:03 | <markit> P4 with 1.5GB ram
| |
| 21:03 | P4@3 ghz
| |
| 21:03 | video board is not very good, sort of SiSomething
| |
| 21:03 | <alkisg> How long does it take to reach the LDM screen?
| |
| 21:04 | <markit> let me negotiate with my children :)
| |
| 21:04 | <alkisg> From the moment that the kernel is loaded, to ldm
| |
| 21:04 | Haha
| |
| 21:04 | Nah never mind let the kids play
| |
| 21:04 | Time for me to go anyway
| |
| 21:04 | <markit> naaaa, too games is not good
| |
| 21:04 | I do it for his health ;P
| |
| 21:04 | <alkisg> Hehe
| |
| 21:04 | <markit> ah, I see
| |
| 21:04 | ok, no problem
| |
| 21:05 | <alkisg> With your specs, I'd say about 20 secs to LDM and another 20 to login
| |
| 21:05 | <markit> KDE in fat looks so slow
| |
| 21:05 | <alkisg> If it takes 20 + 1 minute for you, there's something wrong with the KDE login, or with sshfs, etc
| |
| 21:05 | <markit> server, that is a dual core, goes to KDM in 20 seconds
| |
| 21:05 | <alkisg> Or maybe dns timeouts, etc etc
| |
| 21:06 | <markit> etc etc is my problem
| |
| 21:06 | really I feel myself not good enough to troubleshoot yet
| |
| 21:06 | is like a "ritual"
| |
| 21:06 | if I do things correct, it works
| |
| 21:06 | <alkisg> If it takes 1 minute to reach LDM, then it's another problem
| |
| 21:06 | <markit> if I do some mistake, the God punishes me
| |
| 21:06 | and I have to call alkisg for the rescue
| |
| 21:06 | ;P
| |
| 21:06 | <alkisg> Haha what did you do wrong, burned the food while cooking? :D
| |
| 21:07 | You deserve 5 min boot times then
| |
| 21:07 | <markit> hehehe, I want to script everything to avoid possible mistakes of "oh, yep, that other 51° parameter..."
| |
| 21:08 | dmesg shows NBD_DISCONNECT and googling I've found a chat transcription
| |
| 21:08 | where a certain alkisg says it's normal, it's how LDM checks for a newer version of the nbd disk, to offer to reboot the client
| |
| 21:08 | <alkisg> If it's for /dev/nbd9, ignore it
| |
| 21:08 | Haha
| |
| 21:09 | I've been here too long, time to let others speak more :D
| |
| 21:09 | <markit> :)

| 23:09 | <piet> hi folks, I had been here this afternoon with a question about hostnames already . . .
| |
| 23:11 | ltsp unfortunately doesnt set the dnsdomainname as the hostname of the client . . .
| |
| 23:12 | I didn't find a way to make dhcp giving ltsp this name to handle . . .
| |
| 23:12 | <Hyperbyte> piet, why do you need hostnames like that on your client?
| |
| 23:12 | <piet> it could be easily scripted like <hostname $(hostname -A)> . . .
| |
| 23:13 | @Hyperbyte: because its normal . . .
| |
| 23:14 | in my network the dns-name is e.g. <fibu.medianet> so I want the hostname to be <fibu> . . .
| |
| 23:15 | <Hyperbyte> DNS name is something different than hostname though.
| |
| 23:15 | <piet> the same network handles this (without ltsp) exactly this way . . .
| |
| 23:16 | I have expiriences in ubuntu, suse and gentoo and have never seen it different with dhcp and bind9 working . . .
| |
| 23:17 | only ltsp names my ws <ltsp3>. That makes administration for me more complicated . . .
| |
| 23:17 | <Hyperbyte> piet, since all LTSP clients use the same image, hostname isn't hard-coded but decided dynamically.
| |
| 23:17 | piet, why does it make administration more complicated? I'm trying to understand your actual problem here, to hopefully give you useful advice...
| |
| 23:18 | vagrantc has joined IRC (vagrantc!~vagrant@c-76-105-252-50.hsd1.or.comcast.net) | |
| 23:19 | <piet> I dont wat to have a list aside to translate the <ltsp3> of one of my ws to <fibu> . . .
| |
| 23:20 | dynamically generation is ok but why not <hostname $(hostname -A)>?
| |
| 23:20 | <Hyperbyte> So basically, you want to pre-determine the hostname of LTSP clients?
| |
| 23:21 | <piet> not me, the system automatically . . .
| |
| 23:22 | <Hyperbyte> I'm sorry, I don't understand the question. The system does automatically assign the hostnames, as 'ltsp' and the last digits of the IP address.
| |
| 23:22 | If you want a client that normally uses 'ltsp3' to have a hostname of 'fibu', you can do so in the lts.conf file.
| |
| 23:22 | <piet> and I want it to be equal to its dnsdomainname . . .
| |
| 23:22 | <vagrantc> by default, ltsp clients determine their hostname by prepending ltsp to a number based on the ip address.... but you can change that behavior with configuration values
| |
| 23:23 | should be able to do that
| |
| 23:23 | not sure if we have code for it built in, but it shouldn't be hard to write a patch and get it applied upstream.
| |
| 23:24 | Trixboxer has left IRC (Trixboxer!~Trixboxer@115.124.115.71, Remote host closed the connection) | |
| 23:24 | <piet> I mean I k n o w how ltsp does it . . .
| |
| 23:24 | <vagrantc> although i am merely speaking for ubuntu/debian... i don't know how other distros handle this.
| |
| 23:24 | piet: then file a patch to get it to do what you want.
| |
| 23:24 | <piet> but the normal behaviour under ubuntu in a net is the way I want it to, because its logic, isnt it?
| |
| 23:26 | Im a real newbie in here so pls, what do You mean by <file a patch>?
| |
| 23:27 | <vagrantc> it's free software, propose an actual fix.
| |
| 23:27 | rather than a theoretical one...
| |
| 23:27 | Parker955 is now known as Parker955_Away | |
| 23:27 | <vagrantc> i don't think there will be objection to the idea... it requires some implementation though
| |
| 23:28 | or file a bug, and see if people fix it...
| |
| 23:28 | Parker955_Away is now known as Parker955 | |
| 23:29 | <piet> I tested the small code <hostname $(hostname -A)> and that seems to work on a running ltsp workstation . . .
| |
| 23:31 | but I have absolutely no idea and no plan, where I could place that code. I told You Im an absolute newbie in ltsp and Im realy glad having been lucky to get the whole thing working at all
| |
| 23:32 | <vagrantc> piet: ok, so you've got a feature request, you've got some idea technically what needs to be done ... you use ubuntu?
| |
| 23:32 | <piet> yes
| |
| 23:33 | <vagrantc> so you should file a bug report, i think at launchpad: https://bugs.launchpad.net
| |
| 23:34 | <piet> do You think this is a bug?
| |
| 23:34 | <vagrantc> or a feature request... same difference
| |
| 23:34 | <piet> more a feature than a bug, isnt it?
| |
| 23:35 | <vagrantc> not an important distinction, really.
| |
| 23:36 | <piet> don't You have an idea where I could place this little code-piece? <rc.local> in chroot wouldnt be that good, because the network stuff is not necessarily finished.
| |
| 23:38 | <vagrantc> piet: put it in the chroot (i.e. /opt/ltsp/i386/etc/mycustomrcfile) and use RCFILE_01=/etc/mycustomrcfile
| |
| 23:39 | you'll have to run ltsp-update-image for it to take effect.
| |
| 23:40 | <piet> 1st thing is understood the rcfile doesnt mean anything to me
| |
| 23:41 | <stgraber> vagrantc: hey, I was wondering if you'd be interested in tagging ltsp-docs 1.0 and getting that in Debian? We've been on 0.99~bzrSOMETHING for years now ;)
| |
| 23:43 | <piet> hey my dear fellow English is not my native tongue . . .
| |
| 23:44 | what do You think: a nearly 60 year old guy could do to Your documentation?
| |
| 23:45 | <vagrantc> stgraber: seems reasonable.
| |
| 23:45 | <piet> so what do You mean by <RCFILE_01=/etc/mycustomrcfile> ?
| |
| 23:46 | <vagrantc> piet: add it in lts.conf
| |
| 23:46 | piet: it's a configuration option
| |
| 23:47 | piet: do you have ltsp-docs installed? you can read the manpage for lts.conf: man lts.conf
| |
| 23:47 | <piet> ahhhhhhhhhh, thats what I wanted to hear. thank You, thank You, thank You
| |
| 23:47 | <vagrantc> piet: the manual shipped with ltsp-docs is also useful, in /usr/share/doc/ltsp-docs/
| |
| 23:48 | piet: what do you keep using <> for?
| |
| 23:49 | <piet> little separation of text like quotes but for shure that it will look like it should . . .
| |
| 23:51 | You could also do something like >>Hello<<

| 23:51 | darkpixel_ has left IRC (darkpixel_!~darkpixel@curetheitch/staff/darkpixel, Quit: Leaving.) | |
| 23:52 | <piet> thank U for the hints of documentation <good to know> ;-)
| |
| 23:54 | pls dont missunderstand me, Im not ungradeful. But I have my own project around ubuntu running - with lots of work and just comming from gentooly thin-client project..
| |
| 23:55 | So I dont want to stand up over here trying to tell the cracks of this beautiful software, that is going to minimize my administrational work, how to do there job.
| |
| 23:56 | so pls forgive me, if I dont start a bug-report for <hostname $(hostname -A)> ok?
| |
| 23:59 | isn't there a possibility to set the code-piece into the <lts.conf> file without the detour around a file?
