12:58 | <pem725> can someone help me setup virtualbox for my thin clients? I want my thin clients to be able to boot Windows when necessary. Any help would be greatly appreciated.
| |
12:59 | specifically, I have virtualbox installed but I am not sure how to get the kernel modules to load for the thin client kernels.
| |
13:07 | <alkisg> pem725: vbox clients or vbox server?
| |
13:09 | <johnny> you really don't wanna put vbox in the chroot
| |
13:10 | it's gonna be suck
| |
13:10 | <pem725> good question. I am not sure. The vbox client complains that the kernel driver is not loaded.
| |
13:10 | so I am not sure.
| |
13:10 | <johnny> if you wanna boot windows.. put a hard drive in there
| |
13:10 | <alkisg> pem725: I didn't understand what you want to do, can you elaborate?
| |
13:10 | <johnny> or.. use rdesktop to talk to windows server via remote desktop
| |
13:10 | <pem725> alkisg
| |
13:11 | ok, I have two thin clients that need to use windows but only on rare occasions
| |
13:11 | <johnny> why not install vbox on the server?
| |
13:11 | <pem725> so I wanted to allow them to startup a vbox instance.
| |
13:11 | I have vbox on the server and it runs well.
| |
13:11 | <johnny> so use that..
| |
13:11 | <pem725> can my thin clients access it?
| |
13:11 | how?
| |
13:11 | <johnny> same way?
| |
13:11 | <pem725> sorry for being so obtuse.
| |
13:11 | <alkisg> pem725: so you need rdesktop on the client, and windows vbox on the server, right?
| |
13:11 | <johnny> it should appear in their menu
| |
13:11 | <pem725> ah.
| |
13:12 | yes, it appears in their menu.
| |
13:12 | <johnny> first see if that is fast enough before trying anything else that might be difficult
| |
13:12 | <pem725> alkisg, yes, I think that sounds right.
| |
13:13 | I guess I have vbox setup as a user on the server.
| |
13:13 | <johnny> the open version of virtualbox doesn't support rdesktop service does it?
| |
13:13 | <alkisg> ok, you can do it as johnny said, and if the performance doesn't suit you, you can try to run a local rdesktop from the clients
| |
13:13 | <pem725> ok
| |
13:13 | <alkisg> I think it does
| |
13:14 | <pem725> I have vbox setup on the server but one user has an image setup in his directory.
| |
13:14 | <johnny> pem725, if you run vbox headless with rdesktop.. you can login somewhat more directly (but not really ) and tell your clients to rdesktop to it
| |
13:14 | altho you probably need the appropriate number of licenses for that..
| |
13:14 | <pem725> when I try to run it using that user's profile on the thin client, the vbox program tells me that the kernel module is not loaded.
| |
13:14 | <alkisg> Put the user in the vboxusers group
| |
13:14 | <pem725> licenses are not an issue.
| |
13:14 | ok
| |
13:15 | I will try those suggestions. Thanks for your quick responses.
| |
13:20 | <johnny> ah yes.. that is probably the key
| |
13:20 | putting the user in the group :)
| |
13:20 | hehe

18:26 | <damo221> how do i read mouse events from the local thin client?
| |
18:26 | /dev/input is on the server right/
| |
18:26 | ?
| |
18:27 | <vagrantc> typically, yes.
| |
18:28 | you'll have to get them from the X Display somehow...
| |
18:28 | damo221: what are you trying to do?
| |
18:29 | <damo221> vagrantc: i want to write a script that reads mouse events and sends them to some sort of audio player so i can set up a transcription tool
| |
18:29 | but my machine is an ltsp client.. i got audio to work using pulseaudio
| |
18:30 | <vagrantc> damo221: you'll have to write code that reads it from the X display
| |
18:30 | <damo221> okay....
| |
18:31 | can i do it with bash? or i need something like python
| |
18:32 | i know that bash "read" can read mouse clicks
| |
18:32 | <vagrantc> it would probably be a bad idea to try in bash.
| |
18:33 | <damo221> can php do it? its the only other language i really know
| |
18:33 | lo
| |
18:33 | lol
| |
18:34 | <vagrantc> you just need a language with a decent interface to X
| |
18:34 | <damo221> ok
| |
18:37 | cant i just read some sort of device node
| |
18:37 | hersonls has quit IRC | |
18:37 | <damo221> and parse it
| |
18:38 | <vagrantc> damo221: for the third time, you need to use something that gets it from the X display.

| |
20:09 | <pmatulis> sbalneav: what is cnetworkmanager?
| |
20:11 | <sbalneav> command line interface to network manager
| |
20:11 | try2free has left #ltsp | |
20:11 | <sbalneav> you can control network manager without having to use one of the gui apps
| |
20:12 | sbalneav@phobos:~$ cnetworkmanager -s
| |
20:12 | Active | Name | Type
| |
20:12 | -------+-----------------+--------------- | Ifupdown (eth0) | 802-3-ethernet
| |
20:12 | * | Auto eth1 | 802-3-ethernet
| |
20:12 | So, if you run a low-end laptop, that's running, say, icewm, but you still want the convenience of NM for wireless
| |
20:13 | you can control it with cnetworkmanager
| |
20:14 | <pmatulis> sbalneav: sweet
| |
20:14 | sbalneav: has it been around for a while?
| |
20:15 | <sbalneav> Not too long
| |
20:15 | Anyway there wasn't a debian or ubuntu package for it, so I packaged it.

20:25 | <sl00> Hi. I have installed Fedora 12 and then installed the LTSP package. I have been following the guides but it seems the DHCP is not running or something? I have tried 'service dhcp start' but that fails. What is wrong?
| |
21:10 | rjune has quit IRC | |
21:12 | <sl00> Now the thin client boots up and I get a login screen but when I try to login it just says "verifying.." for a while then the screen flicker with some console text (cannot read it) and then I am back at the login screen for another attempt. Why can I not login and where can I find logs for these failures?
| |
21:13 | <johnny> do you have sshd running?
| |
21:13 | do you have an account on the server?
| |
21:14 | <sl00> 'service sshd status' shows it is running and yes I have tried with two accounts that exist on the server.
| |
21:14 | <vagrantc> sbalneav: cool!
| |
21:17 | <johnny> try sshing to one of em..
| |
21:18 | the logs are on the chroot, so you could add SCREEN_02=shell
| |
21:18 | to your lts.conf and drop into to look at /var/log/ldm.log
| |
21:21 | <sl00> johnny: SSH to the thin client?
| |
21:24 | If I just type 'ssh 172.31.100.100' in a terminal at the server then it says 'connection refused'
| |
21:26 | <pmatulis> for multiple client images, after creating them and assigning a different NBD port to each in inetd.conf do i just need to create corresponding pxelinux.cfg files and configure DHCP appropriately?
| |
21:28 | <vagrantc> or configure pxelinux.cfg to have a menu to select which one to use
| |
21:31 | <pmatulis> vagrantc: that sounds good
| |
21:32 | <vagrantc> depends on if you'd prefer specific thin clients to use a different default, or the users choose
| |
21:32 | <pmatulis> vagrantc: right

21:49 | <sl00> Hm... my /opt/ltsp/i386/etc/lts.conf is empty on the server. Is that correct?
| |
21:49 | I just ran ltsp-build-client.
| |
21:50 | <vagrantc> normally, you only need lts.conf entries if the defaults don't work
| |
21:50 | and some distros now place it in /var/lib/tftpboot/ltsp/i386/lts.conf now
| |
21:51 | <sl00> Okey.. I will check "/var/lib/tftpboot/ltsp/i386/lts.conf" then.
| |
21:52 | <johnny> it might be empty
| |
21:52 | or not there
| |
21:52 | in which case you need to be
| |
21:52 | need to put*
| |
21:52 | [default]
| |
21:53 | before
| |
21:53 | no.. ssh to a user to make sure it works
| |
21:53 | from another computer
| |
21:53 | as ldm just does ssh
| |
21:54 | <sl00> I added SCREEN_02=shell now under [default] in "/var/lib/tftpboot/ltsp/i386/lts.conf" but nothing happends when I press ALT+F2. SCREEN_01 is set to ldm.
| |
21:55 | johnny: I have no other computer right now. Running the server on a netbook (just to get this working) and the client is connected directly to its wired ethernet port.
| |
21:56 | <johnny> you have to reboot it
| |
21:57 | <sl00> Yes I did... but hm... now the login worked!!
| |
21:57 | <johnny> ah.. well good
| |
21:57 | there ya go
| |
21:57 | <sl00> So I guess it works now because I ran ltsp-build.client again... but I do not really understand why it works now and now before tho :(
| |
21:57 | <johnny> maybe you mistyped the password
| |
21:57 | or maybe you had changed the ip of your server
| |
21:58 | in which case you have to run ltsp-update-sshkeys, which is run after ltsp-build-client
| |
21:58 | but can be run manually if your ip changes
| |
21:58 | vagrantc, how come we can't detect that the server ip changed and print that in ldm?
| |
21:58 | and tell people to run ltsp-update-sshkeys on their server
| |
21:59 | <sl00> johnny: Hmm okey.
| |
21:59 | <vagrantc> johnny: how do you distinguish between a hostile server and one where the keys have changed?
| |
22:00 | <johnny> we can mention that either the server ip changed, or something bad happened
| |
22:00 | and say to notify the admin
| |
22:00 | i didn't suggest that we take the new key or anything
| |
22:00 | <vagrantc> at any rate, one of the breakages with the switch to NBD was that you have to rebuild the image every time you change ip addresses because of that
| |
22:00 | <johnny> only notify
| |
22:00 | since when? i've never had t do that on ubuntu?
| |
22:00 | <sl00> johnny: When and why do I have to run ltsp-build-client after this?
| |
22:00 | <johnny> you won't
| |
22:00 | <sl00> (if you know what I mean)
| |
22:00 | <johnny> just run ltsp-update-sshkeys
| |
22:00 | next time
| |
22:00 | if your ip changes
| |
22:00 | server ip*
| |
22:01 | <vagrantc> johnny: how do you propegate the new keys to the NBD image?
| |
22:01 | Egyptian[Home] has joined #ltsp | |
22:01 | <vagrantc> er, key/ip/hostname matching
| |
22:01 | <johnny> oh.. you're right.. :(
| |
22:01 | <sl00> johnny: Okey. So I should not need to run ltsp-build-client ever again?
| |
22:01 | <johnny> duh :(
| |
22:01 | <vagrantc> johnny: you probably don't change the server ip very often.
| |
22:01 | <johnny> you have to urn ltsp-update-image next time..
| |
22:01 | sl00, only if you rebuild the image..
| |
22:01 | afrer deleting the old one
| |
22:02 | if your server ip changes, just run ltsp-update-image then
| |
22:02 | unless fedoar doesn't use nbd.. i can't recall
| |
22:02 | i know gentoo doesn't
| |
22:02 | as we can't control our server kernels
| |
22:02 | <sl00> AFAIK it uses NFS right now.
| |
22:02 | <johnny> ah.. then just ltsp-update-sshkeys
| |
22:03 | <sl00> Okey. I do not think the IP will ever change. What I wonder is what updates to the server requires me to update the image really?
| |
22:04 | <johnny> there is no image
| |
22:04 | if you use nfs
| |
22:04 | but if you did use nbd.. like ubuntu uses by default.. then you would
| |
22:05 | every change to the image (anything affecting client behaviour like ssh keys change, or local apps are installed) would require it then
| |
22:05 | <sl00> johnny: Okey. So if I install say OpenOffice on the server now the client will get it right away?
| |
22:05 | <johnny> yes
| |
22:05 | <sl00> Cool :)
| |
22:05 | <johnny> anyything on the server.. runs on the server..
| |
22:05 | so no client mods necessary..
| |
22:06 | <sl00> johnny: But if I were to run NBD I have to ltsp-update-image?
| |
22:06 | <johnny> yes..
| |
22:06 | <sl00> How much faster/better is NBD over NFS?
| |
22:07 | <johnny> fast enough
| |
22:07 | never benched.. but i could tell the difference
| |
22:07 | <sl00> So NBD is recommended then I guess.
| |
22:08 | <johnny> it is default on ubuntu..
| |
22:08 | not on fedora.. i'm not sure why
| |
22:08 | and definitely not on debian
| |
22:08 | and not on gentoo.. altho for other reasons..
| |
22:09 | /me runs to the store

| |
22:09 | <sl00> Okey..thanks for the help.
| |
22:16 | Seems one of the reasons I could not login with one of the accounts was because the password contains the " character.
| |
22:16 | <vagrantc> if you installed openoffice on the server, you normally wouldn't have to run ltsp-update-image, unless you were using LOCAL_APPS or LTSP_FATCLIENT
| |
22:17 | <sl00> vagrantc: AH I see.
| |
22:18 | <vagrantc> nearly everything happens on the server in a traditional thin client environment: user creation/deletion/managemant, software installs/removals

22:33 | <pmatulis> vagrantc: re multiple images, i now have separate chroots for TFTP (ltsp and ltsp2) but in the pxelinux.cfg/default i'm not sure how to specify the port to use (i have 2000 and 2001 in inetd.conf)
| |
22:34 | (each TFTP chroot has it's own default file)
| |
22:43 | <vagrantc> pmatulis: nbdroot=ip.address.of.server:port
| |
22:44 | maybe nbdport too
| |
22:44 | <pmatulis> this is in the default file?
| |
22:45 | <vagrantc> yeah
| |
22:47 | <sl00> vagrantc: Is it possible to get the fedora login screen, the one I get if I login locally on the server, instead of this k12linux one (ldm)?
| |
22:48 | <johnny> sl00, it's an ldm theme
| |
22:48 | we can't use gdm themes..
| |
22:48 | sl00, try searching the internet to see if somebody has created another ldm theme
| |
22:48 | we don't actually have an ldm theme repository...
| |
22:48 | <vagrantc> and i hear recent versions of gdm have dropped support for logging in over the network...
| |
22:48 | <sl00> Okey.
| |
22:49 | <johnny> vagrantc, that has little to do with using their themes :)
| |
22:49 | <vagrantc> johnny: well, it would be trivial to use GDM's theme if you were logging in via XDMCP using GDM
| |
22:49 | <johnny> sl00, or you would work out how to modify that one
| |
22:49 | vagrantc, sure.. but we don't really recommend that anyways..
| |
22:50 | <sl00> johnny: Will do!
| |
22:51 | Found /opt/ltsp/i386/usr/share/ldm/themes so far... I will play around alittle.
| |
22:52 | <johnny> sl00, there are docs for .gtkrc
| |
22:52 | all over the internet i bet.. so you should be able to figure out.. it's not quite css.. but it does about the same thing..
| |
22:52 | <sl00> Okey
