| 00:01 | <markit> bakytn: no keyboard setting, was wondering if is the case to add one
| |
| 00:02 | and no, I had never such problems too, so I'm surprised
| |
| 00:02 | just for safe, I reboot the server :)
| |
| 00:02 | (some old habbits are hard to die...)
| |
| 00:06 | no way :( wondering if I have to install something special in chroot
| |
| 00:07 | or check if something is missing
| |
| 00:09 | bakytn: do you have kubuntu or ubuntu 11.04?

| 00:18 | <markit> funny, alkis was fighting with a similar bug some year ago
| |
| 00:18 | https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/173067
| |
| 00:18 | This bug fixed in ubuntu hardy
| |
| 00:19 | or maybe mine is a brand new one, lol
| |
| 00:19 | <bakytn> markit, I have ubuntu 11.04 64bit
| |
| 00:19 | <markit> me kubuntu 64 bit, and ltsp chroot at 32 bit
| |
| 00:22 | in chroot /etc/default/keyboard has wrong values
| |
| 00:22 | wondering if I build the chroot before setting locales of the host, but I dubt

| 00:29 | <bakytn> still wondering why the clietns are so slooooow within my cluster network. tcpdump is showing that LDM_DIRECTX is set to True and only on login packets are encrypted

| 00:33 | <markit> bakytn: do you have a gbit switch and 100mb clients?
| |
| 00:34 | <bakytn> markit, yes but it works much much faster on a standalone server
| |
| 00:34 | markit, on the same network
| |
| 00:35 | markit, I have virtual machines so I could compare by shutting down one and turning another on etc.
| |
| 00:35 | <markit> bakytn: can't find my notes about it, but there is a feature in some switch about collisions
| |
| 00:36 | that in some circustamces, like the above, can make it act so dumb that is like a 10MB one
| |
| 00:36 | <bakytn> markit but 10Mb is still very enough to work smoothly
| |
| 00:36 | markit in a local network
| |
| 00:37 | markit, with only one client.
| |
| 00:38 | <markit> oh, I see
| |
| 00:38 | <bakytn> soemthing is wrong with my setup.
| |
| 00:39 | <nroussi> bakytn: ifconfig on the client show lo and eth0 of the client. the server btw is an ldap client and the home directories are on another nfs server. Ldap login and nfs mounts work on the clients but not internet
| |
| 00:40 | <markit> bakytn: what about using tshark and check with visual filters for errors like: tcp.analysis.retransmission or tcp.analysis.out_of_order or tcp.analysis.duplicate_ack_frame or tcp.analysis.lost_segment
| |
| 00:43 | <pmatulis> by default i'm getting extended screen mode with my 2 monitors on my client. how to get mirror mode by default?

| 03:29 | <muppis> Morning.
| |
| 03:30 | Still trying to get up from bed. >)
| |
| 03:32 | <alkisg> Yeah we need better software for that part :-
| |
| 03:32 | Morning :)
| |
| 03:33 | <muppis> I think it's more hardware related at me.
| |
| 03:37 | <computer_freak_8> !gnome-classic
| |
| 03:37 | <ltsp> computer_freak_8: Error: "gnome-classic" is not a valid command.
| |
| 03:37 | <alkisg> !classic-gnome | echo computer_freak_8
| |
| 03:37 | <ltsp> computer_freak_8 classic-gnome: To set classic-gnome as the default session instead of Unity in Ubuntu >= 11.04, put LDM_XSESSION="gnome-session --session=classic-gnome" in lts.conf.
| |
| 03:37 | <computer_freak_8> !classic-gnome
| |
| 03:37 | <ltsp> computer_freak_8: classic-gnome: To set classic-gnome as the default session instead of Unity in Ubuntu >= 11.04, put LDM_XSESSION="gnome-session --session=classic-gnome" in lts.conf.
| |
| 03:38 | <computer_freak_8> ha, yeah, I was a bit slow on the re-type
| |
| 03:38 | now I don't have to keep scrolling :)
| |
| 03:43 | So, I'm working on the auto-login, but I noticed something: if I use the remote-login feature (XDMCP), it does the auto-login sequence exactly as I have told it to. However, when the LTSP client boots, it goes to the LTSP login screen.
| |
| 03:44 | I don't know if this is a configuration goof, or if that is normal.
| |
| 03:45 | <alkisg> computer_freak_8: XDMCP is a protocol to connect to a remote X display server, unrelated to autologin and ltsp
| |
| 03:45 | Autologin in LTSP only works with the LDM display manager
| |
| 03:46 | <computer_freak_8> Okay.... so maybe I need to transfer that (working) config from my server "main" to my server's chroot?
| |
| 03:46 | <alkisg> I think you should start with saying what you want to do
| |
| 03:47 | <computer_freak_8> get the autologin working, but have it be easily configurable.
| |
| 03:47 | <alkisg> autologin is already working, did you read the lts.conf man page about the configuration variables?
| |
| 03:47 | It just needs 3 lines in lts.conf
| |
| 03:47 | !lts.conf
| |
| 03:47 | <ltsp> alkisg: lts.conf: http://manpages.ubuntu.com/lts.conf.
| |
| 03:47 | <computer_freak_8> Yeah, it didn't work.
| |
| 03:47 | <alkisg> Paste your current lts.conf then
| |
| 03:47 | <computer_freak_8> let me try again, though
| |
| 03:48 | <alkisg> LDM_AUTOLOGIN, LDM_USERNAME, LDM_PASSWORDS
| |
| 03:48 | *without the S
| |
| 03:48 | You just need to set those 3 variables
| |
| 03:50 | <computer_freak_8> Nope, didn't work
| |
| 03:50 | <alkisg> (06:47:58 πμ) alkisg: Paste your current lts.conf then
| |
| 03:50 | Put xxx in place of the password
| |
| 03:51 | <computer_freak_8> Eh, I'm just using a test password: http://pastebin.com/8bYn44qV
| |
| 03:51 | that's the actual password for the user "guest", but I'll change it once I get it all working.
| |
| 03:51 | <alkisg> And if you try to login on LDM with guest/test, it works?
| |
| 03:52 | <computer_freak_8> username "guest"/password "pass"
| |
| 03:52 | <alkisg> guest/pass
| |
| 03:52 | <computer_freak_8> yeah, it logs in
| |
| 03:52 | <alkisg> OK, once it logs in, run: ltsp-localapps xterm
| |
| 03:52 | Did an xterm open?
| |
| 03:54 | <computer_freak_8> I hit [Alt]+[F2] to bring up that prompt, but yes, it does.
| |
| 03:54 | <alkisg> In that xterm, run: getltscfg -a
| |
| 03:54 | <computer_freak_8> "guest@ltsp196~$"
| |
| 03:54 | <alkisg> Do you see LDM_USERNAME/LDM_PASSWORD etc in the output?
| |
| 03:54 | <computer_freak_8> okay, it spit back:
| |
| 03:54 | no, I don't....
| |
| 03:55 | it has two lines:
| |
| 03:55 | <alkisg> On your server, ls /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 03:55 | <computer_freak_8> LTSP_CONFIG=True
| |
| 03:55 | <alkisg> Ah
| |
| 03:55 | <computer_freak_8> and export LTSP_CONFIG
| |
| 03:55 | <alkisg> You're the one that uses debian and switched to nbd by mistake, right?
| |
| 03:55 | <computer_freak_8> wait, it has double-quotes around the "True"
| |
| 03:55 | yup!
| |
| 03:55 | <alkisg> Debian uses nfs, and /opt/ltsp/i386/etc/lts.conf by default
| |
| 03:56 | <computer_freak_8> okay.
| |
| 03:56 | <alkisg> Since you switched to nbd, you shouldn't use that file
| |
| 03:56 | <computer_freak_8> Oh!
| |
| 03:56 | <alkisg> Because every time you change it, you also need to run ltsp-update-image, which takes a lot of time
| |
| 03:56 | <computer_freak_8> oh....
| |
| 03:56 | <alkisg> So with nbd, lts.conf was moved to /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 03:56 | Just copy your lts.conf there
| |
| 03:56 | <computer_freak_8> is there an easy way to switch back to NFS?
| |
| 03:57 | <alkisg> Not sure about all that's needed, if you see vagrantc around here ask him
| |
| 03:57 | <computer_freak_8> Ah, okay.
| |
| 03:57 | <alkisg> You may have to change a couple of configuration files for bind_mounts etc
| |
| 03:57 | <computer_freak_8> oh, okay.
| |
| 03:58 | <alkisg> For now it's not a big deal, just use /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 03:58 | <computer_freak_8> Does the /var/lib/tftpboot/ltsp directory basically mirror the /srv/tftp/ltsp directory?
| |
| 03:58 | <alkisg> You only need one of those, delete the other
| |
| 03:59 | There's a transitional period from /var/lib/tftpboot to /srv/tftp where both of them are supported
| |
| 03:59 | <computer_freak_8> I only modify the /srv/tftp directory contents, but it auto-propagates to the /var/lib/tftpboot directory (somehow...)
| |
| 03:59 | <alkisg> No, don't do that
| |
| 03:59 | Just delete one of the 2
| |
| 03:59 | <computer_freak_8> okay.
| |
| 04:00 | <alkisg> It makes no sense to have to update both of them
| |
| 04:00 | <computer_freak_8> I'll delete the /var/lib/tftpboot one then..
| |
| 04:00 | <alkisg> Yup, completely rm -rf it
| |
| 04:00 | <computer_freak_8> and put my configuration at /srv/tftp/ltsp/i386/lts.conf, then?
| |
| 04:00 | <alkisg> Yes
| |
| 04:00 | Also you may need to update your tftp server
| |
| 04:00 | So that it points to /srv/tftp
| |
| 04:01 | Probably /etc/default/tftpd-hpa
| |
| 04:01 | <computer_freak_8> yeah, it already does
| |
| 04:02 | is NFS or NBD better for low-RAM capacity thin (diskless) clients, or does it matter?
| |
| 04:03 | <alkisg> The main pros/cons:
| |
| 04:03 | Compressed NBD is maybe 5 times faster. That mostly affects boot time, localapps and fat clients
| |
| 04:04 | <computer_freak_8> Oh, okay
| |
| 04:04 | <alkisg> And, with NFS, you don't need to run ltsp-update-image every time you change /opt/ltsp/i386/*
| |
| 04:04 | <computer_freak_8> which is nice
| |
| 04:04 | <alkisg> Select which of the above is more significant for you...
| |
| 04:04 | <computer_freak_8> is one being depreciated? or just newer?
| |
| 04:04 | I prefer NFS in that case
| |
| 04:04 | <alkisg> None. Debian defaults to NFS, while Ubuntu to NBD, mainly for the boot speed
| |
| 04:05 | <computer_freak_8> oh, okay
| |
| 04:05 | <alkisg> E.g. if one only updates his chroot every few months, why not have that extra speed
| |
| 04:05 | <computer_freak_8> true.
| |
| 04:05 | <alkisg> But while setting up a chroot, ltsp-update-image is a pain in the *
| |
| 04:05 | <computer_freak_8> I'm always changing things
| |
| 04:06 | comes in handy to have it ready right away
| |
| 04:07 | wait, is this correct? Or do I need to bump it down a directory, into an "etc" sub-directory? sudo cp -a /opt/ltsp/i386/etc/lts.conf /srv/tftp/ltsp/i38
| |
| 04:07 | 6/
| |
| 04:07 | <alkisg> No etc
| |
| 04:07 | <computer_freak_8> okay. cool
| |
| 04:09 | Is there an easy way to keep ltsp-update-image from messing up my /srv/tftp/ltsp/i386/pxelinux.cfg/default file?
| |
| 04:09 | Sweet, autologin works - and I didn't even have to run the ltsp-update-image!
| |
| 04:09 | <alkisg> It shouldn't be touching it unless you specify the --force option
| |
| 04:09 | <computer_freak_8> Thanks.
| |
| 04:09 | hm, odd.
| |
| 04:10 | <alkisg> If it does, I'd consider it a bug...
| |
| 04:10 | <computer_freak_8> each time I have run it so far, it replaces it - and I have to fix it.
| |
| 04:10 | <alkisg> cat /opt/ltsp/i386/boot/pxelinux.cfg/default
| |
| 04:10 | Maybe it calls ltsp-update-kernels, which copy that file
| |
| 04:11 | In that case, you can either run ltsp-update-image --force, which updates both files, or just edit that file too
| |
| 04:11 | <computer_freak_8> could be - one has :
| |
| 04:11 | label ltsp
| |
| 04:11 | kernel vmlinuz
| |
| 04:11 | append ro initrd=initrd.img
| |
| 04:11 | and the other:
| |
| 04:11 | label ltsp
| |
| 04:11 | kernel ltsp/i386/vmlinuz
| |
| 04:11 | append ro initrd=ltsp/i386/initrd.img
| |
| 04:11 | (that's not the whole thing - just the changed parts)
| |
| 04:11 | it must think my root is different?
| |
| 04:13 | (the real location is in the "ltsp/i386/" directory - it always strips that part, though)
| |
| 04:14 | But hey, auto-login works, so thanks again - I'm all set until I break it again!

| 08:08 | <reuss_> hi, I have some problem with dhcp in ltsp: this is a mixed network with clients that boot from pxe, the others not. The problem is with these last ones: they could not connect to the internet. Any clue? Please...
| |
| 08:13 | I would like to ensure that the ltsp server become a simple network gateway for the non pxe booters.

| 08:33 | <Hyperbyte> Morning Alkis. :)
| |
| 08:36 | <alkisg> Hey Neo
| |
| 08:37 | <reuss_> hyperbyte: ltsp clients do connect the internet
| |
| 08:38 | <alkisg> reuss_: https://help.ubuntu.com/community/UbuntuLTSP/ThinClientHowtoNAT
| |
| 08:40 | <reuss_> alkisg: hi again, I am checking. I found finally on a french forum the steps to configure italc and updated the ubuntu help page too with it.
| |
| 08:41 | <alkisg> Thanks, I hope people can follow the new page :)
| |
| 08:43 | We should make a bonus system, every person updating a wiki page would be entitled to one good answer in irc :P :D
| |
| 08:44 | <Hyperbyte> reuss_, the 'other non-pxe clients'... are those Linux machines as well, or Windows?
| |
| 08:46 | <reuss_> hyperbyte: both
| |
| 08:46 | hyperbyte: for now, it is a linux client
| |
| 08:46 | <Hyperbyte> Okay
| |
| 08:46 | Run 'ifconfig' and 'ip route show' on the Linux client that can't connect to the internet, and pastebin those
| |
| 08:46 | !pastebin | echo reuss_
| |
| 08:46 | <ltsp> reuss_ pastebin: the LTSP pastebin is at http://ltsp.pastebin.com. Please paste all text longer than a line or two to the pastebin, as it helps to reduce traffic in the channel. Don't forget to paste the URL of the text here..
| |
| 08:48 | <reuss_> hyperbyte, ltsp: it would be difficult without a connection, but I am trying to connect it from the server by ssh
| |
| 08:49 | <Hyperbyte> ifconfig > debuginfo.txt
| |
| 08:49 | ip route show >> debuginfo.txt
| |
| 08:49 | scp debuginfo.txt user@ltspserver
| |
| 08:49 | That'll copy the file to a user's home directory on the LTSp server
| |
| 08:58 | <reuss_> hyperbyte: I copied it, but I cant see it on the server...
| |
| 08:58 | <Hyperbyte> Sorry
| |
| 08:59 | You need a colon after that

| 08:59 | Without the : it copies the file locally, like 'cp' would.
| |
| 09:00 | <reuss_> hyperbyte: I got it
| |
| 09:00 | <Hyperbyte> :)
| |
| 09:01 | <reuss_> hyperbyte: here is: http://paste.ubuntu.com/673644/
| |
| 09:01 | <Hyperbyte> And you said your main router is 192.168.1.111 ?
| |
| 09:02 | <reuss_> hyperbyte: yes, but the ltsp server hides it
| |
| 09:02 | <Hyperbyte> What is 192.168.0.1 ?
| |
| 09:02 | <reuss_> hyperbyte: the ltsp server dhcp offers addresses on 192.168.0.0
| |
| 09:03 | hyperbyte: nothing
| |
| 09:04 | <Hyperbyte> And you are 100% sure your LTSP clients -can- connect to the internet?
| |
| 09:04 | Or do you mean the applications running on the server, displayed on the thin client, can connect to the internet? :-)
| |
| 09:05 | Because if that's the case, your thin clients in fact can not connect to the internet, and you'll need to follow the howto that Alkis posted a bit earlier.
| |
| 09:06 | Thin clients by default run everything on the server. If you start Firefox on a thin client, it doesn't actually run on the client, it runs on the server. So it's the server that's connecting to the internet, not the clients. The clients probably can't access the internet themselves, you'd need to set up NAT for that.
| |
| 09:07 | <reuss_> hyperbyte: booting as thin client with pxe, I can connect to internet, the chroot environment could too, only this fat client without pxe could not
| |
| 09:07 | <Hyperbyte> Okay
| |
| 09:07 | <reuss_> hyperbyte: I am checking the doc and will report its success (if any). thanks
| |
| 09:07 | <Hyperbyte> Boot a thin client, and start a local xterm
| |
| 09:07 | !localxterm
| |
| 09:07 | <ltsp> Hyperbyte: localxterm: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client..
| |
| 09:08 | <Hyperbyte> And type ping 192.168.1.111
| |
| 09:08 | If that doesn't work, you need to set up NAT. :-)
| |
| 09:14 | <reuss_> hyperbyte: ping 192.168.1.111 ping: icmp open socket: operation not permitted
| |
| 09:26 | <Hyperbyte> Oh, nuts.
| |
| 09:26 | Well you could try via
| |
| 09:26 | !SCREEN_02
| |
| 09:26 | <ltsp> Hyperbyte: SCREEN_02: to get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using%20a%20shell%20SCREEN.
| |
| 09:26 | <Hyperbyte> If you're really curious to confirm that your clients cannot access the internet
| |
| 09:29 | <alkisg> By default, the thin clients behind 2-nic servers cannot access the internet, so I'm not sure if it's worth all the troubleshooting to verify that this is indeed the case...
| |
| 09:29 | Once reuss_ enables ip forwarding and NAT, he'll be able to verify the result with the standalone client

| 10:25 | <Hyperbyte> mgariepy, your trick with disabling transparency doesn't work. My thin client still freezes completely while printing those files.
| |
| 10:26 | reuss_, you're welcome
| |
| 10:28 | <reuss_> hyperbyte: just a last question: if I install gimp, firefox in the chroot environment, this will decrease the network load?
| |
| 10:41 | <alkisg> reuss_: yes, localapps need much less bandwidth, if your client specs are good enough for them
| |
| 10:51 | Trixboxer has joined IRC (Trixboxer!~Trixboxer@office.supportdepartment.net) | |
| 10:51 | <Hyperbyte> reuss_, gimp sounds like a pretty heavy load for a thin client though. What hardware (cpu/ram) do your clients have?
| |
| 10:52 | Parker955_Away is now known as Parker955 | |
| 10:52 | <reuss_> athlon 1700
| |
| 10:52 | hyperbyte: athlon xp 1700 or similar with 400 mb ram
| |
| 10:53 | hyperbyte: with 10 clients, it worked fine when the gimp was running on the server
| |
| 10:58 | <Hyperbyte> reuss_, it's your choice. If your server + network is powerful enough ...
| |
| 10:58 | 400 MB ram isn't a lot, but should be able to handle Firefox. Dunno about Gimp.
| |
| 11:00 | <alkisg> How is "400 MB RAM" possible? 256+128+16 ?
| |
| 11:01 | <reuss_> alkisg: 400 something mb, with shared video ram maybe from 512
| |
| 11:01 | <alkisg> Which graphics card? It matter for youtube etc...
| |
| 11:01 | <reuss_> alkisg: mostly integrated nvidias from 5 years ago
| |
| 11:02 | <alkisg> That's pretty good then, if you enable the proprietary driver
| |
| 11:02 | Then yeah, firefox+flash locally would be better than from the server
| |
| 11:03 | <reuss_> alkisg: thanks, I will implement it then. from the server, it was sometimes quite slow (but a lot better then a non maintened windows xp)
| |
| 11:04 | <alkisg> You need to install the proprietary driver in the chroot, and enable it on selected clients from lts.conf
| |
| 11:05 | Also enable and increase nbd_swap (or some local swap partition, if your clients have local disks)
| |
| 11:05 | Otherwise you'll probably get firefox crashes, too little ram
| |
| 11:05 | Parker955 is now known as Parker955_Away | |
| 11:08 | <reuss_> alkisg: If i have firefox installed both in chroot and server and local_apps_menu enabled on ltsp.conf and I dont want anymore the clients to run from clients, I remove at chroot and that is all?
| |
| 11:09 | s/to run/to run firefox
| |
| 11:09 | alkisg: s/to run/to run firefox
| |
| 11:09 | <alkisg> You can also just remove it from lts.conf
| |
| 11:09 | But yeah, that's about it
| |
| 11:10 | If you want, it's easy to keep a backup from your whole /opt/ltsp directory...
| |
| 11:10 | sudo rsync -a /opt/ltsp /opt/ltsp-before-trying-localapps
| |
| 11:11 | <reuss_> alkisg: after every installation, I should run tsp-update-image ?
| |
| 11:12 | <Hyperbyte> reuss_, modifications to /opt/ltsp/ only apply after running ltsp-update-image
| |
| 11:12 | <alkisg> !learn ltsp-update-image as If you use NBD (e.g. Ubuntu), every time you change something in your chroot (e.g. /opt/ltsp/i386), you need to run ltsp-update-image and reboot the thin clients for the changes to take effect

| |
| 14:10 | <tl1000s77> Quick question, I'm trying to get sound working on my thin client (Ubuntu 10.04 ) using rdesktop and the -r sound:local command but it's not working. Should I install ltspfs on the thin client or is that only for local devices?
| |
| 14:12 | <Gadi> tl1000s77: what version of windows
| |
| 14:12 | (and no to the ltspfs question)
| |
| 14:12 | <tl1000s77> Server 2008 R2
| |
| 14:12 | <Gadi> and audio mapping is enabled on the server?
| |
| 14:12 | <tl1000s77> I get sound using rdesktop from my desktop and that's running ubuntu 10.10
| |
| 14:13 | Yes
| |
| 14:13 | <Gadi> are you running ldm and rdesktop on 2 different screens?
| |
| 14:13 | <tl1000s77> No
| |
| 14:13 | I'm using the SCREEN_07 = rdesktop
| |
| 14:14 | <Gadi> try setting SOUND=False in lts.conf - this will, in effect, disable pulseaudio and volume adjustment, but alsa sound will still work
| |
| 14:14 | it could be that sound via pulseaudio on the client is not working
| |
| 14:15 | <tl1000s77> I have tried that, can I show you my lts.conf file?
| |
| 14:16 | <Hyperbyte> nroussi, type 'ifconfig' and 'ip route show' on the client, then put the output on pastebin.
| |
| 14:17 | <Gadi> tl1000s77: sure
| |
| 14:17 | tl1000s77: also, get a shell on another screen (say, screen2)
| |
| 14:18 | that way, you can debug some things on the client
| |
| 14:23 | <tl1000s77> Gadi: I also wanted to ask you about the XRANDR variable, it doesn't seem to call --addmode anywhere.

| |
| 14:39 | <shawnp0wers> I thought Edubuntu didn't use Unity, but I guess I"m wrong… :(
| |
| 14:39 | <Gadi> tl1000s77: and the -f (not needed)
| |
| 14:40 | -f and -u '' are automatically added
| |
| 14:40 | <Hyperbyte> shawnp0wers, search the IRC logs for user Hyperbyte and text classic-gnome
| |
| 14:40 | <shawnp0wers> ok thanks Hyperbyte
| |
| 14:40 | <Gadi> tl1000s77: and why not put the server at the end, so you have one line
| |
| 14:41 | <Hyperbyte> Alternatively....
| |
| 14:41 | !classic-gnome
| |
| 14:41 | <ltsp> Hyperbyte: classic-gnome: To set classic-gnome as the default session instead of Unity in Ubuntu >= 11.04, put LDM_XSESSION="gnome-session --session=classic-gnome" in lts.conf.
| |

| |
| 14:41 | <tl1000s77> the -f isn't added...I just took it out and it's not in full screen mode anymore :)
| |
| 14:42 | <Gadi> what?
| |
| 14:42 | somebody messed with the script, then
| |
| 14:42 | sigh
| |
| 14:43 | <tl1000s77> mine is a vanilla install...I promise :)
| |
| 14:43 | <Gadi> can you paste: /opt/ltsp/i386/usr/share/ltsp/screen.d/rdesktop
| |
| 14:43 | <anivair> Anyone know a good way to figure out what ip addresses the ghcp on my server is currently assigning?
| |

| 14:53 | For some reason i thought it JustWorked™ — but for the life of me I can't figure it out
| |
| 14:53 | <Gadi> shawnp0wers: try setting REMOTE_APPS = True
| |
| 14:54 | alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg) | |
| 14:54 | <tl1000s77> I still have the rdesktop session...
| |
| 14:54 | <dberkholz> ltsp just work? that would kill off a whole consulting industry =P
| |
| 14:54 | <shawnp0wers> If that does it, I may crap a brick. Just a warning… ;)
| |
| 14:54 | <tl1000s77> it's line 30 that we're talking about changing right?
| |

| 14:55 | <Gadi> tl1000s77: yes
| |
| 14:56 | <tl1000s77> Gadi: That didn't work, can I just change my lts.conf file and restart the thin client?
| |
| 14:56 | <Gadi> change your lts.conf to what, tho?
| |
| 14:57 | <tl1000s77> ldm?
| |
| 14:57 | <Gadi> if you like, you can change that file in the chroot and update the chroot temporarily
| |
| 14:57 | no, you dont want ldm
| |
| 14:58 | <tl1000s77> k
| |
| 14:58 | <Gadi> if you make that change and update the chroot, when you reboot, you should get an xterm instead of rdesktop
| |
| 14:58 | from the xtrem, we can try:
| |
| 14:58 | 1. playing a sound with aplay
| |
| 14:58 | 2. checking the volume levels with alsamixer
| |
| 14:59 | 3. running rdesktop from command line with the params and see if we can play a sound
| |
| 14:59 | <alkisg> rm rdesktop at the filesystem level, and symlink it to xterm :P
| |
| 14:59 | <Gadi> yeah, or that
| |
| 14:59 | without changing the chroot
| |
| 14:59 | <alkisg> Yup, while the thin client runs, not in the server chroot
| |
| 14:59 | <Gadi> and, whaa...... alkisg is back!
| |
| 14:59 | :)
| |
| 14:59 | <alkisg> !Gadi
| |
| 14:59 | <ltsp> alkisg: Error: "Gadi" is not a valid command.
| |
| 14:59 | <alkisg> !g
| |
| 14:59 | <ltsp> alkisg: g: Gadi!!!!!!!!!!!!!!!!!!!!!!!!.
| |
| 15:00 | <nroussi> alkisg, I followed your guide to do the NATing but I need some help. Can you take a look at this: http://pastebin.com/PEUG83dn
| |
| 15:00 | <Gadi> alkisg: so you changed behavior of rdesktop screeen script on me
| |
| 15:00 | :)
| |
| 15:00 | my advice is totally useless now
| |
| 15:00 | :P
| |
| 15:00 | <anivair> dhcpd.conf tells me what the range is. i'm looking fora list of addresses already assigned currently
| |
| 15:00 | <alkisg> Gadi: hey, I asked you 5-6 times to comment on the changes :D
| |
| 15:00 | <Gadi> I am deaf in that ear
| |
| 15:00 | :)
| |
| 15:01 | <alkisg> Gadi: it made more sense to me this way, I didn't like having to specify half of the command line... either no command line (RDP_OPTIONS, RDP_SERVER etc), or full command line
| |
| 15:01 | And, omitting "-f" and "-u" wasn't anywhere on the docs
| |
| 15:02 | ...erm, and rdesktop, RDP_OPTIONS etc too :P
| |
| 15:02 | <Gadi> nothing but excuses
| |
| 15:02 | :)
| |
| 15:02 | * alkisg admits he only has lame excuses to offer | |
| 15:02 | <Gadi> think of all the poor people who just added one or two params
| |
| 15:02 | and upgrade to find that root wants to now login!
| |
| 15:02 | <alkisg> But I heard that good excuses make up for poor code quality :D
| |
| 15:03 | <Gadi> you should add -f -u '' to the COMMAND line
| |
| 15:03 | rdesktop will override them with later params
| |
| 15:03 | ie, -u '' -u foo brings up the user foo
| |
| 15:04 | <shawnp0wers> Gadi: Ok, I haven't shat a brick quite yet, but I'm close. The REMOTE_APPS directive is working for 11.04. However, it doesn't work for .doc attachments. Is there a way to configure mime types for ltsp-open ?
| |
| 15:04 | <alkisg> Gadi, but why modify the default rdesktop command line anyway?
| |
| 15:04 | <Gadi> shawnp0wers: ltsp-open calls xdg-open on the server
| |
| 15:04 | so, if you associate it on the server, it should work
| |
| 15:05 | <shawnp0wers> That's strange, on the server a quick double-click opens them fine...
| |
| 15:05 | <tl1000s77> I now have a small xterm window
| |
| 15:05 | Parker955 is now known as Parker955_Away | |
| 15:05 | <tl1000s77> but it's only a bash
| |
| 15:05 | shell
| |
| 15:05 | <shawnp0wers> Perhaps I should clarify — firefox doesn't even try to open .doc attachments with ltsp-open
| |
| 15:05 | <Gadi> tl1000s77: right
| |
| 15:05 | tl1000s77: perfect
| |
| 15:05 | first, try playing a sound with aplay
| |
| 15:06 | (say, some wav file in /usr/share/sounds/)
| |
| 15:06 | <tl1000s77> I get sound with aplay
| |
| 15:06 | <Gadi> tl1000s77: ok, now run rdesktop -r sound:local -u '' 10.1.1.10
| |
| 15:07 | <tl1000s77> no sound :(
| |
| 15:08 | <alkisg> nroussi: you tell the clients that your gateway is 192.168.0.1 while it's 192.168.0.254. Your server is the gateway to your clients.
| |
| 15:09 | nroussi: so change " option routers 192.168.0.1;" to " option routers 192.168.0.254;"
| |
| 15:09 | In dhcp.conf, router means the gateway. And for your clients, the gateway is your server, it does NAT for them.
| |
| 15:09 | <nroussi> alkisg: ok let me try that, thanks
| |
| 15:12 | <Gadi> tl1000s77: how are you testing sound in Windows?
| |
| 15:14 | <tl1000s77> I open up Sound, and try to play one of the sounds
| |
| 15:14 | scottmaccal has left IRC (scottmaccal!~scottmacc@firewall.portland.lib.me.us, Ping timeout: 250 seconds) | |
| 15:14 | <tl1000s77> Doing it that way from my Ubuntu desktop works
| |
| 15:15 | <Gadi> ok
| |
| 15:16 | log out of windows, so it drops you back to the xterm
| |
| 15:16 | are tehere any errors in the xterm?
| |
| 15:16 | *there
| |
| 15:16 | <tl1000s77> only a warning about colour depth, but nothing about sound
| |
| 15:17 | <Gadi> yeah, I noticed you set 24 bit - a no no for w2k8r2
| |
| 15:17 | (you should either use 16 or 32)
| |
| 15:17 | but thats a different story
| |
| 15:17 | <tl1000s77> I'll change that now
| |
| 15:17 | <Gadi> note: if you choose 32, make sure your video driver can do that
| |
| 15:18 | and you need to add: -a 32 to the rdesktop line
| |
| 15:18 | <tl1000s77> will do
| |
| 15:18 | <Gadi> maybe it is a problem with rdesktop?
| |
| 15:18 | what version do you have there?
| |
| 15:19 | Parker955_Away is now known as Parker955 | |
| 15:19 | <tl1000s77> 1.6.0
| |
| 15:19 | <Gadi> oh, and in the current scenario, is pulseaudio running or not?
| |
| 15:21 | <tl1000s77> I don't think so, I did a ps -ef and I didn't see it
| |
| 15:21 | Gremble has joined IRC (Gremble!~Ben@cpc12-aztw24-2-0-cust146.aztw.cable.virginmedia.com) | |
| 15:22 | <Gadi> hmmm
| |
| 15:22 | all very strange
| |
| 15:22 | <alkisg> tl1000s77: ubuntu? which version?
| |
| 15:22 | <Gadi> and nothing in the Windows event viewer
| |
| 15:22 | <tl1000s77> 10.04
| |
| 15:22 | <alkisg> tl1000s77: do you want to temporarily install xfreerdp from my ppa and try with that?
| |
| 15:23 | <tl1000s77> I'll try anything
| |
| 15:23 | <Gadi> xfreerdp is better anyway
| |
| 15:23 | :)
| |
| 15:23 | <alkisg> Gadi, I haven't read all the conv, am I interrupting any experiments?
| |
| 15:23 | <Gadi> no, go ahead
| |
| 15:23 | <alkisg> ok, let me write the commands...
| |
| 15:24 | <nroussi> alkisg: thanks. It is working now
| |
| 15:24 | nroussi has left IRC (nroussi!~nroussi@209.155.76.243, Quit: Leaving) | |
| 15:25 | <tl1000s77> nothing in the logs on the windows server
| |
| 15:26 | dtcrshr has joined IRC (dtcrshr!data@unaffiliated/datacrusher) | |
| 15:26 | <alkisg> sudo chroot /opt/ltsp/i386
| |
| 15:26 | apt-get update
| |
| 15:27 | apt-get --yes install python-software-properties
| |
| 15:27 | add-apt-repository ppa:ts.sch.gr
| |
| 15:27 | apt-get update
| |
| 15:27 | apt-get --yes install freerdp-x11
| |
| 15:27 | rm /etc/apt/sources.list.d/ts.sch.gr-ppa-lucid.list

| |
| 15:27 | exit #from chroot
| |
| 15:27 | sudo ltsp-update-image
| |
| 15:27 | tl1000s77: ^
| |
| 15:28 | Ping me on any warnings/errors etc
| |
| 15:28 | (of the above commands)
| |
| 15:30 | And modify your lts.conf so that you call "xfreerdp params" instead of "rdesktop params"
| |
| 15:33 | <tl1000s77> Great. Everything installed OK, Now I need to change the lts.conf
| |
| 15:34 | Should I change my rdesktop back to what it was instead of /usr/bin/xterm?
| |
| 15:34 | <Gadi> yes
| |
| 15:36 | so, we often get asked "How can I help with LTSP?"
| |
| 15:36 | do we have that somewhere on our website?
| |
| 15:36 | :)
| |
| 15:36 | <tl1000s77> :)
| |
| 15:36 | <alkisg> "To help with LTSP, write a web site about that"
| |
| 15:36 | <Gadi> I feel like we do wonderful things and get propelled along by the random contributions of folks who pass like ships
| |
| 15:36 | <alkisg> (about how to help with ltsp :P)
| |
| 15:37 | <Gadi> we should definitely discuss this in October at BTS
| |
| 15:37 | if not before
| |
| 15:37 | brb
| |
| 15:37 | <shawnp0wers> Today is proving to be mind numbing. I would like to turn today off and turn it back on. :)
| |
| 15:37 | <alkisg> I think that the wiki is the only item in the BTS agenta :)
| |
| 15:38 | So I'm sure we/you'll talk about that part
| |
| 15:38 | <shawnp0wers> Does anyone know how to tell firefox to globally use a certain program to open a certain type of file? (Yes, more ltsp-open stuff)
| |
| 15:38 | <tl1000s77> alkisg, does xfreerdp take the same commands as rdesktop?
| |
| 15:38 | <alkisg> tl1000s77: not exactly, the sound param is different, see the script that you pasted in pastebin
| |
| 15:39 | or use man xfreerdp
| |
| 15:39 | <shawnp0wers> I can do it for my user, in prefs, but while .odt and .pdf are automagically assigned to ltsp-open, .doc is not...
| |
| 15:39 | <alkisg> tl1000s77: the equivalent of "-r sound:local" is "--plugin rdpsnd"
| |
| 15:43 | <tl1000s77> something like this under the mac address of the client: SCREEN_07 = "xfreerdp -f -a 16 -d ssww --plugin rdpsnd 10.1.1.10"
| |
| 15:43 | <alkisg> tl1000s77: sounds good
| |
| 15:43 | Not sure about the -d (domain)
| |
| 15:43 | Is it in the man page?
| |
| 15:43 | Yup it is
| |
| 15:43 | <tl1000s77> yes
| |
| 15:45 | how can I tell that it's using the xfreerdp instead of rdesktop?
| |
| 15:46 | Would that be from the shell?
| |
| 15:46 | <alkisg> tl1000s77: ps -ef|grep xfreerdp
| |
| 15:47 | <Gadi> shawnp0wers: I believe it grabs everything from the server's /usr/lib/mime/packages directory
| |
| 15:47 | <tl1000s77> ok, it's using it
| |
| 15:47 | anivair has left IRC (anivair!~joe@69.58.115.123, Quit: Leaving) | |
| 15:48 | <tl1000s77> still no sound :(
| |
| 15:49 | <Gadi> tl1000s77: the user you are using in windows has logged out and logged in, right?
| |
| 15:49 | and is not blocked by a policy?
| |
| 15:49 | <tl1000s77> Gadi: many times
| |
| 15:50 | no group policies in place to block sound
| |
| 15:50 | <Gadi> ie, it is that same user that gets sound from ubuntu desktop?
| |
| 15:50 | ie ubuntu desktop -> rdesktop
| |
| 15:50 | <tl1000s77> correct
| |
| 15:50 | <shawnp0wers> Gadi: That makes sense, but I can't find *any* reference to ltsp-open anywhere. I have no idea where that action is coming from.
| |
| 15:51 | <Gadi> shawnp0wers: let me tell ya how it works
| |
| 15:51 | (since it was mgariepy and myself who coded it over beer)
| |
| 15:51 | :)
| |
| 15:51 | <shawnp0wers> :D
| |
| 15:51 | I may have found something in /usr/share/ldm/rc.d/X01-remoteapps
| |
| 15:51 | parsing that now...
| |
| 15:52 | <Gadi> right
| |
| 15:52 | so it grabs the files from /usr/lib/mime/packages on the server and copies them locally
| |
| 15:52 | then does a bunch of editing to call ldm-open instead of whatever it is that they call
| |
| 15:53 | well, cctually, I think we make one file on the client
| |
| 15:53 | /usr/lib/mime/packages/ltsp
| |
| 15:53 | and play with the priority
| |
| 15:54 | so that admins can optionally prefer a locally installed app to a remote one
| |
| 15:54 | it was all very clever after the third bottle or so
| |
| 15:54 | <shawnp0wers> Gadi: Ok, that at least makes sense. And I do see (in a live chroot) that the mime/packages files are changed. I need to figure out why firefox isn't using ltsp-open for .doc files now
| |
| 15:55 | but I have a place to look, thank you so much. :)
| |
| 15:55 | <Gadi> np - btw, I know we tested with doc files
| |
| 15:55 | and they worked
| |
| 15:55 | <shawnp0wers> maybe it's my firefox prefs that are screwy
| |
| 15:55 | <Gadi> maybe
| |
| 15:55 | * shawnp0wers goes to check | |
| 15:55 | <Gadi> can you try a fresh user account?
| |
| 15:56 | and you said when you click on a doc, it doesnt prompt you to open with ltsp-open, right?
| |
| 15:57 | (maybe you had at one point told firefox to "always open docs with soffice" or some such
| |
| 15:57 | <shawnp0wers> just deleted my firefox prefs completely
| |
| 15:57 | <Gadi> and now, it is still doing that
| |
| 15:57 | <shawnp0wers> and no, when opening a DOC file, it doesn't ask to open with
| |
| 15:57 | just defaults to save
| |
| 15:57 | <Gadi> huh
| |
| 15:57 | <shawnp0wers> with no options in the "open with" area
| |
| 15:57 | <Gadi> doc or docx?
| |
| 15:58 | <shawnp0wers> doc
| |
| 15:58 | <tl1000s77> Is there anything else I can try to get the sound working?
| |
| 15:58 | <shawnp0wers> attached in gmail
| |
| 15:58 | <tl1000s77> It didn't work with xfreerdp
| |
| 15:59 | <Gadi> shawnp0wers: what if you do a google search for: filetype:doc test
| |
| 16:00 | <shawnp0wers> same issue
| |
| 16:00 | but .odt works fine
| |
| 16:00 | oy
| |
| 16:01 | <tl1000s77> brb
| |
| 16:01 | <shawnp0wers> I'll keep playing with it. Thanks for the quick "how it works" tutorial. :)
| |
| 16:01 | <Gadi> np
| |
| 16:02 | tl1000s77: xfreerdp actually spits out much more to the command line. So, it may help you debug better. Oh, wait! Also check /proc/asound/cards
| |
| 16:02 | and see how many cards youhave listed
| |
| 16:03 | perhaps there is more than one and something is getting confused

| 18:46 | <alkisg> dgroos: hi, remember https://bugs.launchpad.net/sch-scripts/+bug/761717?
| |
| 18:47 | <dgroos> alkisg: howdy, indeed.
| |
| 18:47 | <alkisg> I need some testing, if it's easy for you as I won't be near a lab for some time
| |
| 18:47 | loather-work has joined IRC (loather-work!~khudson@206.169.71.12) | |
| 18:47 | <dgroos> not going to be a problem with remote apps?
| |
| 18:48 | <alkisg> No no just speed testing
| |
| 18:48 | <dgroos> I don't have any thin clients set up--just fat'uns
| |
| 18:48 | <alkisg> You can just set LTSP_FATCLIENT=False in lts.conf
| |
| 18:48 | If you have some time for the test, that is
| |
| 18:49 | Ah, it doesn't even matter, fats will also do
| |
| 18:49 | <dgroos> I'd be happy to test later on this afternoon, I'm a bit under a schedule right now
| |
| 18:49 | <alkisg> Sure, or tomorrow, no hurry
| |
| 18:50 | <dgroos> sure, can you describe it or does it have to be back-and-forth?
| |
| 18:50 | <alkisg> What I wanted to test is if -noshm makes a difference in broadcasting speed when the teacher is seated on the server and the clients are thin
| |
| 18:51 | (the lack of -noshm in this case)
| |
| 18:51 | In all other cases, we can put -noshm there
| |
| 18:51 | But if even on that first case it doesn't make things go faster, then we can always put -noshm there without special casing anything
| |
| 18:51 | So the test is:
| |
| 18:51 | 1) put LTSP_FATCLIENT=False in lts.conf
| |
| 18:51 | 2) put the -noshm bit (I think you already have that there)
| |
| 18:52 | 3) Sit on the server (...i don't know if that's easy for you... vnc?) and start broadcasting
| |
| 18:52 | Then, remove -noshm and do that again, and see if it's faster
| |
| 18:52 | <dgroos> I've got openNX working great...
| |
| 18:52 | <alkisg> If it's not, we don't need to special case it
| |
| 18:52 | <dgroos> right.
| |
| 18:53 | <alkisg> Thanks!
| |
| 18:53 | <dgroos> Is there some sort of numerical metric or just looking for 'as best it seems...'?
| |
| 18:53 | <alkisg> iftop is some numerical metric, but just looking also does it for me :)
| |
| 18:54 | If you can't see a difference, I'll just always put -noshm there
| |
| 18:54 | (iftop running on the server)
| |
| 18:54 | <dgroos> for sure, makes sense.

| 19:27 | Parker955_Away is now known as Parker955 | |
| 19:33 | <alkisg> tl1000s77: so you say that you have sound on the thin client, but not with rdesktop/xfreerdp, but if you run the same command on a standalone ubuntu pc, you get sound from the w2008 server?
| |
| 19:34 | <tl1000s77> alkisg: yes. In the xterm session on the thinclient I have sound, but with rdesktop or xfreerdp nothing
| |
| 19:34 | <alkisg> And the next part, about the standalone ubuntu pc connecting to the w2008 server?
| |
| 19:34 | with rdesktop ?
| |
| 19:35 | <tl1000s77> Yes that works too with rdesktop
| |
| 19:35 | <alkisg> OK, let's see if it's hardware specific
| |
| 19:35 | Try to (1) boot the thin client from an ubuntu live usb stick, or
| |
| 19:36 | (2) boot that standalone pc as a thin client, from your ltsp server
| |
| 19:36 | <tl1000s77> When I boot into the thin client using the ldm desktop I get sound
| |
| 19:36 | <alkisg> Maybe there's something in your hardware that confuses rdesktop
| |
| 19:36 | So testing with different hardware helps there
| |
| 19:36 | shogunx has joined IRC (shogunx!~shogunx@rrcs-67-79-182-235.se.biz.rr.com) | |

| |
| 19:52 | I get sound on the tc but not using rdesktop to the server...

| 19:58 | <alkisg> So it's not at all LTSP related. Maybe hardware related, e.g. rdesktop may be sending the sound to some unused output of your sound card.
| |
| 19:58 | If you can, also try (2)
| |
| 19:59 | <tl1000s77> k
| |
| 19:59 | before I do that, would there be something in the logs?
| |
| 19:59 | <alkisg> Maybe... open the log viewer, and THEN run rdesktop
| |
| 19:59 | And see if some log file gets bold

| |
| 20:12 | <Gadi> tl1000s77: have you tried: -r sound:local:oss
| |
| 20:12 | (with rdesktop)
| |
| 20:12 | <tl1000s77> Gadi: no, not yet
| |
| 20:12 | <Gadi> maybe alsa is not really working
| |
| 20:12 | and you need the old oss method
| |
| 20:12 | <tl1000s77> I'll try that now
| |
| 20:12 | <Gadi> or try: -r sound:local:alsa
| |
| 20:12 | maybe it is the other way
| |
| 20:12 | :)
| |
| 20:13 | of course, if pulseaudio is running, I doubt oss will work
| |
| 20:13 | because it would hog the device
| |
| 20:14 | you would need to have pulseaudio-utils installed and run: padsp rdesktop -r sound:local:oss ....
| |
| 20:14 | loather-work has joined IRC (loather-work!~khudson@206.169.71.12) | |
| 20:14 | <Gadi> alkisg: remember all that yummy pasuspender/padsp from the screen script... ;)
| |
| 20:14 | we must have had that for some corner case somewhere
| |
| 20:14 | :)
| |
| 20:15 | <alkisg> Hey Gadi
| |
| 20:15 | I asked and asked and only mgariepy said he needed those,
| |
| 20:15 | but then he realized that SOUND=False was better, so he didn't need them anymore
| |
| 20:15 | Where do you need those?
| |
| 20:16 | <Gadi> ah
| |
| 20:16 | :)
| |
| 20:16 | <alkisg> And if you do, I think they should be generic, not specific to the rdesktop script
| |
| 20:16 | <Gadi> Im just messin with ya
| |
| 20:16 | <alkisg> Haha
| |
| 20:16 | <Gadi> I hear ya
| |
| 20:16 | * alkisg wasn't reading the conv... looking up... | |
| 20:16 | <tl1000s77> Even using tsclient it doesn't work...frustrating...
| |
| 20:17 | <Gadi> I think they may have crept in for things like running ldm on one screen and rdesktop on another and wanting sound
| |
| 20:17 | but pulseaudio being greedy
| |
| 20:17 | or something
| |
| 20:17 | I dunno
| |
| 20:17 | tl1000s77: tsclient uses rdesktop
| |
| 20:18 | so, makes sense that it doesnt
| |
| 20:18 | <alkisg> Gadi, previously pulseaudio needed exclusive access to the soundcard, now it works alongside alsa, so ldm/rdesktop isn't a problem
| |
| 20:18 | <Gadi> alkisg: ah legacy workarounds
| |
| 20:18 | :)
| |
| 20:18 | loather-work has left IRC (loather-work!~khudson@206.169.71.12, Ping timeout: 258 seconds) | |
| 20:18 | <tl1000s77> got it!! with the sound:local:oss
| |
| 20:19 | <Gadi> yay
| |
| 20:19 | <alkisg> From the early pulse days where everyone was cursing and wanted it gone etc :D
| |
| 20:19 | <Gadi> hehe
| |
| 20:19 | most of ltsp is working around stuff
| |
| 20:19 | :)
| |
| 20:19 | <tl1000s77> You guys rock!! Thank you!!
| |
| 20:19 | <Gadi> then the stuff gets fixed and we are left with workarounds
| |
| 20:19 | :)
| |
| 20:19 | <alkisg> hehe
| |
| 20:19 | <Gadi> tl1000s77: only took us weeks, right?
| |
| 20:19 | :D
| |
| 20:20 | <alkisg> ...and uncomprehensible code
| |
| 20:20 | <tl1000s77> no matter how long it took...you guys stuck through it!
| |
| 20:20 | I'll try it now on the tc running off of the ltsp server
| |
| 20:21 | <Gadi> tl1000s77: btw, sounds like an alsa driver bug with that particular sound card or something
| |
| 20:21 | if it has to use the oss emulation
| |
| 20:21 | I mean, great that it works, dont get me wrong
| |
| 20:21 | :)
| |
| 20:21 | <alkisg> Or maybe rdesktop sends the sound to some unused output and it's an rdesktop/xfreerdp bug
| |
| 20:21 | <Gadi> true
| |
| 20:21 | could be the frequency mismatch
| |
| 20:21 | or something
| |
| 20:22 | there's a lot of crap like that in this world
| |
| 20:22 | unfortunately for most engineers, they are illiterate and can't read the standard specs
| |
| 20:22 | :)
| |
| 20:22 | <tl1000s77> :)
| |
| 20:22 | <Gadi> I think standards docs should be written as anime cartoons
| |
| 20:23 | then, things would work better
| |
| 20:23 | <alkisg> Nah, something with porn would work better than cartoons :P
| |
| 20:23 | <Gadi> then NOTHING would get coded
| |
| 20:23 | <alkisg> Haha
| |
| 20:24 | <Gadi> and the keyboards would get all sticky
| |
| 20:24 | <alkisg> But the coders would know the standards in depth :P
| |
| 20:24 | <Gadi> and bts would be a much weirder experience
| |
| 20:24 | (than it already is)
| |
| 20:24 | :)
| |
| 20:26 | <alkisg> That's because the ltsp devs are stinky phallocrates and don't accept women in their team
| |
| 20:26 | How many female applications you turned down? dozens...
| |
| 20:26 | <Gadi> phallocrates?
| |
| 20:26 | <tl1000s77> So do I still need the sound=false with sound:local:oss?
| |
| 20:26 | <Gadi> is that some greek philosopher?
| |
| 20:26 | <alkisg> Haha
| |
| 20:26 | <Gadi> lol
| |
| 20:26 | * alkisg couldn't find a better word in his dict :P | |
| 20:26 | <alkisg> *translation
| |
| 20:27 | <Gadi> ha!
| |
| 20:27 | * Gadi wonders what dictionary | |
| 20:27 | <Gadi> lol
| |
| 20:27 | <alkisg> tl1000s77: if it works from the usb stick, you shouldn't need it, but it's better to have SOUND=False when you use rdesktop anyway
| |
| 20:27 | It uses less memory, it's just a bit faster, etc
| |
| 20:28 | <Gadi> http://www.merriam-webster.com/dictionary/phallocratic
| |
| 20:28 | nice
| |
| 20:29 | <tl1000s77> ok, so still no sound using rdesktop with my lts.conf looking like this...SCREEN_07 = "rdesktop -f -a 16 -d domain -r sound:local:oss 10.1.1.10"
| |
| 20:29 | <Gadi> there's a new toilet paper word of the day for me
| |
| 20:29 | :)
| |
| 20:29 | tl1000s77: with SOUND=False?
| |
| 20:29 | <tl1000s77> yes
| |
| 20:30 | <Gadi> when it worked, were you using padsp?
| |
| 20:30 | <bakytn> mgariepy, hi you helped me yesterday, just wanted to Thank you!
| |
| 20:30 | <tl1000s77> What is padsp?
| |
| 20:30 | <Gadi> I guess not, then :)
| |
| 20:30 | <alkisg> Try with SOUND=True too :P
| |
| 20:30 | <Gadi> yeah - do what alkisg says

| |
| 20:32 | <mgariepy> bakytn you are welcome!
| |
| 20:32 | <tl1000s77> I logged into the thin client via ldm desktop, got sound, tried to use rdesktop with sound and it didn't work. Even with sound:local:oss
| |
| 20:33 | <Gadi> using rdesktop from the ldm session?
| |
| 20:33 | <tl1000s77> Gadi: yes

| 20:33 | <Gadi> oh!
| |
| 20:33 | bakytn_ has joined IRC (bakytn_!~bakytn@31.29.17.125) | |
| 20:33 | <Gadi> well, for ldm, you need SOUND=True
| |
| 20:33 | otherwise you won't get any sounds
| |
| 20:33 | oh, but you did get
| |
| 20:33 | so it is true
| |
| 20:33 | bakytn has left IRC (bakytn!~bakytn@31.29.17.125, Read error: Operation timed out) | |
| 20:33 | <Gadi> do you have padsp on the server?
| |
| 20:34 | <tl1000s77> I don't know, how do I look for it?
| |
| 20:34 | <Gadi> oh wait
| |
| 20:34 | but with -r sound:local you DO get sound in an ldm session
| |
| 20:34 | right?
| |
| 20:34 | that makes complete sense
| |
| 20:34 | <alkisg> He does?!
| |
| 20:34 | <Gadi> in ldm it needs to use alsa so it can forward to pulse
| |
| 20:34 | <alkisg> And it makes sense?!
| |
| 20:34 | <tl1000s77> I get the regular sounds on the ldm session, but not using rdesktop
| |
| 20:35 | <Gadi> not with :oss , but without it does
| |
| 20:35 | (i thought)
| |
| 20:35 | if you use ldm to connect to the server and run rdesktop, you need:
| |
| 20:35 | SOUND=True
| |
| 20:36 | rdesktop -r sound:local
| |
| 20:36 | if SOUND=False, you get no sounds
| |
| 20:36 | if rdesktop -r sound:local:oss you get no rdesktop sound
| |
| 20:36 | that all makes sense
| |
| 20:36 | <tl1000s77> OK, so I changed that to SOUND=True and try rdesktop with sound:local...but using SCREEN_07 = rdesktop ... sound:local:oss didn't work
| |
| 20:37 | <Gadi> have you tried:
| |
| 20:37 | SOUND=False
| |
| 20:37 | <alkisg> ..but using SCREEN_07 = rdesktop ... sound:local:oss didn't work ==> that's both with SOUND=False and True?
| |
| 20:37 | <Gadi> SCREEN_07 = "rdesktop -r sound:local:oss ...
| |
| 20:37 | because that combination should work
| |
| 20:37 | <tl1000s77> Yes with SOUND=False for the SCREEN_07
| |
| 20:38 | alkisg: yes
| |
| 20:38 | Gadi: it should...but it doesn't
| |
| 20:39 | <alkisg> tl1000s77: and, with SOUND=True, ldm, login, and rdesktop -r sound:local ?
| |
| 20:39 | <Gadi> get a shell on the client and do: lsmod|grep oss
| |
| 20:39 | <tl1000s77> Using ldm with rdesktop and SOUND=True and rdesktop sound:local didn't work either
| |
| 20:39 | <Gadi> maybe thae alsa-oss driver is not loaded
| |
| 20:40 | <alkisg> It's not loaded in my lucid laptop either...
| |
| 20:40 | <tl1000s77> I don't see alsa-oss but I do see snd
| |
| 20:40 | <Gadi> do you see: snd_pcm_oss
| |
| 20:41 | <tl1000s77> yes
| |
| 20:41 | first one
| |
| 20:41 | <Gadi> and snd_mixer_oss

| 20:41 | hmm
| |

| 21:58 | <anivair> umm ... so I edited by dhcpd.conf to shorten my range and now I can't start dhcp services. Any advice?
| |
| 21:58 | changing it back doesn't seem to help
| |
| 21:58 | which confounds me

| |
| 22:01 | that's it
| |
| 22:03 | .... or it just came back up
| |
| 22:03 | I tried to start it like three times to no effect, now it comes up ... i didn't change anything
| |
| 22:03 | very odd, but this is me not looking the gift horse in the mouth right yet
| |
| 22:04 | <Hyperbyte> anivair, look at the /var/log/dhcpd.log if it's there
| |
| 22:04 | Else start dhcpd manaually, it'll spit out the errors as well then.
| |
| 22:08 | <anivair> log not there, sadly
| |
| 22:08 | I rebooted the server, edited dhcpd.conf and started manually
| |
| 22:08 | <Hyperbyte> No need to reboot the server
| |
| 22:09 | <anivair> (I didn't reboot it for that, i rebooted it because we had network issues before and it was easier than killing everyone one at a time)
| |
| 22:09 | but I got the generic "errr in your conf file operation not permitted" error
| |
| 22:09 | and then it just came back up
| |
| 22:10 | <Hyperbyte> dhcpd spits out 'error in your config file' and still starts?
| |
| 22:10 | <anivair> oh! i am so stupid!
| |
| 22:10 | no, it spit that out and would not start
| |
| 22:10 | .... because I was no running the start as root
| |
| 22:10 | wow, i'm dumb
| |
| 22:10 | this is why I should never admin under pressure
| |
| 22:11 | it "magically" started when I did a sudo su to make my commands easier
| |
| 22:11 | dumb dumb
| |
| 22:11 | okay, please ignore me
| |
| 22:11 | happy night
