| 01:28 | <tech_dvo> can I use multiple nic cards in a server?
| |
| 01:28 | to serve thin clients?
| |
| 01:29 | <muppis> tech_dvo, haven't done that, but I don't see any reason why not.
| |
| 01:38 | <alkisg> Sure, I've used 4
| |
| 01:42 | <tech_dvo> how do I do that? :)
| |
| 01:42 | <alkisg> Either put them on separate subnets or use bonding
| |
| 01:42 | <tech_dvo> how do I set it up?
| |
| 01:43 | <alkisg> Which of those two you want? Separate subnets (IPs) or all of them with the same IP like one card?
| |
| 01:44 | <tech_dvo> which is easier to maintain?
| |
| 01:45 | <alkisg> How are your clients wired?
| |
| 01:45 | How many switches, how many clients, how are those connected etc?
| |
| 01:45 | <tech_dvo> one big subnet -- around 50 clients
| |
| 01:46 | 4 16port switch
| |
| 01:46 | 100Mbps
| |
| 01:47 | <alkisg> And the switches are interconnected? Again at 100 mbps?
| |
| 01:48 | <tech_dvo> yes
| |
| 01:48 | interconnected
| |
| 01:48 | <alkisg> First of all 100 mbps is tooooooo slow for 50 clients
| |
| 01:49 | And even if you put 4 nics on the server and go up to 400 mbps, it'll still be too slow
| |
| 01:49 | I'd use 4 *gigabit* nics on the server if I were you, to get the network bandwidth up to 4 gbps
| |
| 01:49 | <tech_dvo> okay
| |
| 01:50 | <alkisg> Since you have 4 switches, it's easier to use different IPs on the server
| |
| 01:50 | And only update /etc/ltsp/dhcpd.conf
| |
| 01:50 | So put IP1 = 192.168.0.10, IP2=192.168.1.10, IP3=xxx, 4 separate subnets
| |
| 01:50 | <tech_dvo> okay -- that sounds easy enough
| |
| 01:55 | is there a sample reference for this?

| 02:10 | <gnunux> hi
| |
| 02:19 | dobber has joined #ltsp | |
| 02:20 | <tech_dvo> Hi gnunux
| |
| 02:21 | basically this is a dhcp server thing -- if all goes well at dhcp then ltsp is okay?
| |
| 02:27 | <alkisg> Yes
| |
| 02:31 | <tech_dvo> thanks, I got it.
| |
| 02:41 | <alkisg> Btw you'll need to un-connect the switches for this to work well
| |
| 02:41 | As you'll have 4 dhcp servers running
| |
| 02:42 | (1, listening on 4 interfaces)
| |
| 02:47 | <tech_dvo> 1 dhcp server port per switch, right?
| |
| 02:48 | hmmmm...where do my router or the internet fit in?
| |
| 02:48 | do I have to set up NAT for this?
| |
| 02:50 | <alkisg> For thin clients you don't need NAT
| |
| 02:50 | For fat or localapps, you do
| |
| 02:50 | The router can be in any switch
| |
| 02:54 | (10:47:23 AM) tech_dvo: 1 dhcp server port per switch, right? ==> the dhcp port will be the same, i.e. port 68. The IP will be different, i.e. the static one you've defined for that NIC.
| |
| 03:04 | <tech_dvo> yup, sorry -- what I mean is the rj45 outlet
| |
| 03:07 | where can I disable one user logging into many clients?
| |
| 03:09 | <alkisg> !lts.conf
| |
| 03:09 | <ltspbot> alkisg: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
| |
| 03:09 | <alkisg> Read about the LDM_LIMIT_ONE_SESSION variable there

| 04:43 | <tech_dvo> why do I get the message: INFO task lsb_release:356 blocked for more than 120 seconds
| |
| 04:44 | /proc/sys/kernel/hung_task_timeout_secs" disable this message
| |
| 04:45 | and it's not booting -- this is one thin client that I specified to use XSERVER=vesa
| |
| 04:45 | using the [mac:address] then XSERVER=vesa
| |
| 04:45 | in lts.conf
| |
| 04:54 | <alkisg> It might be yet another problem with nbd proxy: https://bugs.launchpad.net/ltsp/+bug/589034
| |
| 05:02 | <tech_dvo> how do I troubleshoot thin clients that doesn't go back to login window after a log out -- it's just a black screen
| |
| 05:03 | i tend to restart to thin client -- but that is inconvenient when restarting more than 10 and at different location in the classroom
| |
| 05:03 | <alkisg> Heh, you do have a lot of problems with LTSP, don't you?
| |
| 05:04 | <tech_dvo> hehehe -- seems that way, but I don't mind as long as I can make it work
| |
| 05:04 | <alkisg> Did you solve the nbd problem?
| |
| 05:05 | It might be related to other types of hangs...
| |
| 05:05 | So solve that first before you try to troubleshoot them all at once
| |
| 05:05 | <tech_dvo> the error i got before, just disappeared. I used the program you gave me. maybe it just need to wait for the internet traffic to slow down and everythings fine
| |
| 05:06 | i manage to load the login from two different thin clients
| |
| 05:06 | diff in video cards
| |
| 05:06 | <alkisg> The nbd-proxy problem doesn't happen all the time
| |
| 05:06 | <tech_dvo> used the man page link you gave me
| |
| 05:06 | <alkisg> So you might see hangs 1-2 times out of 10
| |
| 05:07 | <tech_dvo> I also have thin clients NIC (Davicom) that doesnt boot well
| |
| 05:07 | <alkisg> What do you mean? Error messages? When does it stop? etc
| |
| 05:07 | Be more descriptive
| |
| 05:08 | <tech_dvo> let me see...
| |
| 05:16 | alkisg:i'll try to catch you next time -- had to go out -- something came up. thanks for your expertise, sir. :)

| 07:35 | <_UsUrPeR_> morning all
| |
| 07:35 | having problems with a 10.04 ltsp installation that will not mount USB storage devices
| |
| 07:35 | running lsusb, the device is detected
| |
| 07:36 | in dmesg, the drive is assigned a device name (sda in this case)
| |
| 07:36 | it's capable of being mounted on the client if I do it manually from root
| |
| 07:37 | however, it does not mount itself and show up on the desktop

| 07:50 | <mgariepy> good morning everyone
| |
| 07:50 | <_UsUrPeR_> here's a pastebin of /ver/log/messages http://pastebin.com/CDangzK2
| |
| 07:50 | mgariepy: good morningh
| |
| 07:50 | (the h is silent)
| |
| 07:50 | <mgariepy> hehe :)
| |
| 07:50 | <_UsUrPeR_> ...or mis-typed
| |
| 07:51 | about the pastebin: again, this is a problem I am having with a 10.04 server which is not automatically mounting USB storage devices
| |
| 07:51 | as you can see, there is no problem with detection
| |
| 07:52 | <mgariepy> is your user member of fuse group
| |
| 07:52 | ?
| |
| 07:53 | what's the permission on /dev/fuse ?
| |
| 07:54 | <_UsUrPeR_> let me check
| |
| 07:55 | <mgariepy> i'll be back in 30 minutes or so.
| |
| 07:55 | i'll continue helping you then
| |
| 07:55 | <_UsUrPeR_> ok
| |
| 08:05 | mgariepy: yeah, the user is part of the fuse groups
| |
| 08:05 | I am running ltsp-cluster, btw
| |
| 08:05 | though this has not been a problem in the past
| |

| 08:14 | * _UsUrPeR_ waves at shawnp0wers | |
| 08:14 | <_UsUrPeR_> Gadi: ping?
| |
| 08:14 | <shawnp0wers> Howdy _UsUrPeR_!
| |
| 08:14 | <Gadi> no Gadis - only us penguins
| |
| 08:14 | <_UsUrPeR_> shawnp0wers: how's the school business going? All well I hope.
| |
| 08:14 | * Gadi shivers | |
| 08:15 | <_UsUrPeR_> Gadi: pm'ing you with an issue I posted up here before you got on
| |
| 08:15 | don't want to flood
| |
| 08:17 | <shawnp0wers> _UsUrPeR_: Meh, same old same old. I haven't had to log into my new LTSP servers in months though, so there's that. :)
| |
| 08:18 | <robehend1> shawnp0wers: ha, how did you manage that ;)
| |
| 08:18 | <shawnp0wers> robehend1: They just work. Really, once they're set up, they tend to just work.
| |
| 08:18 | <_UsUrPeR_> shawnp0wers: hey nice. Nothing like predictability and reliability.
| |
| 08:18 | though it does make for a boring time at work :/
| |
| 08:19 | <shawnp0wers> heheh, I've got lots of other computers to work on. :)
| |
| 08:19 | (Including my old LTSP server, which is long in the tooth, with even older clients)
| |
| 08:19 | When your client computers are P133's, you're bound to have headaches. :)
| |
| 08:20 | But the new LTSP 5 servers are great.
| |
| 08:20 | Along with their new thin clients
| |
| 08:20 | <robehend1> what kind of specs, may I ask? in the process of designing a new infastructure for a new building going in this fall
| |
| 08:21 | <shawnp0wers> the thin clients are from disklessworkstations.com — the 1620 I think
| |
| 08:21 | The servers are actually old rackmount servers I recommissioned this year
| |
| 08:21 | dual 3.2Ghz, 32bit Xeon
| |
| 08:21 | They have 6GB of RAM
| |
| 08:22 | I'm actually running a lab of 32 thin clients from one of those servers
| |
| 08:22 | with localapps, the server load is fairly low
| |
| 08:23 | Yeah, this is the thin client I use: http://www.disklessworkstations.com/200122.html?id=IysAWXqp
| |
| 08:23 | Plus the vendor (ahem… _UsUrPeR_ …ahem) is really great to work with. :)
| |
| 08:23 | I'm using Ubuntu 10.04.1 for the server OS, only because that's what was out when I installed it.
| |
| 08:24 | <_UsUrPeR_> :D
| |
| 08:24 | * _UsUrPeR_ blushes | |
| 08:24 | <mgariepy> _UsUrPeR_, how about the permission of /dev/fuse ?
| |
| 08:25 | and do you have ltspfsd and ltspfsd-core installed in your chroot ?
| |
| 08:25 | <_UsUrPeR_> sorry was just discussing this very problem with Gadi
| |
| 08:25 | * Gadi recognizes mgariepy as the authority | |
| 08:25 | <Gadi> :)
| |
| 08:26 | and yields the floor
| |
| 08:26 | <mgariepy> ok then no problem ;)
| |
| 08:26 | <_UsUrPeR_> but yeah, ltspfs is installed on both appserves
| |
| 08:26 | I am not seeing anything mounted in /media when connecting
| |
| 08:28 | <robehend1> shawnp0wers: hmm, i've been looking at those. Currently, i'm running fat-clients on some old p4s and celerons, but we're looking to go more green..
| |
| 08:29 | <mgariepy> what's in your lts.conf ?
| |
| 08:29 | <shawnp0wers> robehend1: Power usage was huge for us. Not because we're eco-friendly, sadly, but because the room just didn't have the power for 32 computers.
| |
| 08:29 | <mgariepy> in /var/cache/getltscfg-cluster/lts.conf
| |
| 08:30 | <shawnp0wers> But with LCD monitors and those thin clients, we haven't had a problem with power or heat
| |
| 08:30 | <_UsUrPeR_> mgariepy, one moment and I'll get that
| |
| 08:32 | <robehend1> shawnp0wers: we're looking for power and heat, as the building is extremely low in budget. Do you think one of those would be a decent fat client? looks like its netbook-like for specs, so i'd assume so..
| |
| 08:33 | <_UsUrPeR_> mgariepy, http://pastebin.com/U0KhhK6a
| |
| 08:33 | that's the lts.conf
| |
| 08:34 | <shawnp0wers> robehend1: It's basically a netbook without a screen. It has no hard drive, but booting a complete OS would probably be very doable. I like LTSP for the central point of configuration, but if you're booting an OS image, and just mounting /home — it would probably work fine.
| |
| 08:34 | In fact, I'd like to know how it works if you do it — there would be some advantage to that setup. :)
| |
| 08:34 | <robehend1> shawnp0wers: we want the single point of config as well, but since the kids like to do things with Openshot and PiTiVi, i've found fat clients work the best.
| |
| 08:35 | ha, for sure. I take extra care to document all my steps, to the command
| |
| 08:39 | <mgariepy> the permission on /dev/fuse on the applications server are ok ?
| |
| 08:40 | <robehend1> shawnp0wers: out of curiosity, how warm does that 1620 get with extended operation? I've used things like the Zotac box and Acer Revo, and they got warm, same specs/size
| |
| 08:40 | <_UsUrPeR_> mgariepy: what should they be set at?
| |
| 08:41 | <shawnp0wers> I think it gets *warm* to the touch, but not hot. Since there is no fan, I think the heat it does create stays local, and is easier to notice. I think similar computers with fans get just as hot, but send the heat to the atmosphere more efficiently
| |
| 08:41 | <_UsUrPeR_> mgariepy: right now the permissions are as follows: crw-rw-rw- 1 root:fuse
| |
| 08:41 | <shawnp0wers> the room itself doesn't heat up though, which isn't true withfull computers crammed in there.
| |
| 08:41 | <mgariepy> 0 crw-rw-rw- 1 root fuse 10, 229 2011-01-02 18:18 /dev/fuse
| |
| 08:41 | hmm does the usb mounts on the thin client itself ?
| |
| 08:42 | <_UsUrPeR_> mgariepy: it does not mount, however it is detected, and may me mounted manually
| |
| 08:43 | i.e. mount /dev/sda1 /home/Desktop/whatever etc...
| |
| 08:43 | that needs to be run locally from the client
| |
| 08:44 | <mgariepy> ok. on the appserv, does it mounts somewherE?
| |
| 08:45 | ex: /tmp/.whatever
| |
| 08:45 | toscalix has quit IRC | |
| 08:45 | toscalix has joined #ltsp | |
| 08:46 | <_UsUrPeR_> mgariepy: I am not seeing any detected USB connections or mount attempts on the appserve logs, nor do I see anything pertaining to the USB storage device in /tmp/.anything.
| |
| 08:47 | <mgariepy> ps aux | grep ltspfsmounter
| |
| 08:47 | <_UsUrPeR_> mgariepy: here's a ls of /tmp/ http://pastebin.com/4vfeB35b
| |
| 08:49 | mgariepy: output of ps aux http://pastebin.com/XwPLCNyp
| |
| 08:49 | directories in /tmp/ltsp-localapps-jsass-5p5gPb/ are applications and icons
| |
| 08:52 | <mgariepy> yeah, when the usb key is in the thin client do you have a directory : /var/run/drive/usbdisk-* ?
| |
| 08:53 | <_UsUrPeR_> mgariepy: I see one, but it is empty
| |
| 08:54 | on the client locally
| |
| 08:55 | <robehend1> shawnp0wers: hmm, alright. I'm going to have to see if i can order one, to give it a shot. right after i figure out how if testnav will run on ubuntu ;)
| |
| 09:00 | <shawnp0wers> robehend1: Also, if you want to try LTSP, using localapps works great for intensive applications
| |
| 09:00 | I have a CAD program running as a local app, and it works great
| |
| 09:03 | <robehend1> shawnp0wers: I did localapps before I went to thin clients. Works great for most things, I agree.
| |
| 09:04 | <shawnp0wers> cool, then I'm even MORE interested in your fat client results. :D
| |
| 09:04 | Not that there's anything wrong with LTSP. (pats the #ltsp channel on the back)
| |
| 09:04 | ;)
| |
| 09:04 | <robehend1> I've got fat clients currently running on all my ltsp deployments, actually
| |
| 09:04 | <_UsUrPeR_> mgariepy: any further ideas?
| |
| 09:05 | I am wondering if a rebuild of the cleint image may be a good idea
| |
| 09:07 | <mgariepy> _UsUrPeR_, can you try to add the LOCALDEV=True in your configuration ?
| |
| 09:08 | which version of ltsp do you have ?
| |
| 09:09 | komunista has joined #ltsp | |
| 09:09 | <_UsUrPeR_> mgariepy, ltsp-server 5.2.1-0ubuntu9
| |
| 09:11 | also ltsp-cluster-lbserver 2.0.0-0ubuntu2, ltsp-cluster-lbagent 2.0.2-pubuntu1, ltsp-cluster-control 2.0.200ubuntu1 ltsp-cluster-accountmanger 2.0.3-0ubuntu1
| |
| 09:11 | mgariepy: ^^
| |
| 09:11 | I will set localdev=true
| |
| 09:12 | mgariepy, LOCALDEV is not an option in cluster's admin interface
| |
| 09:13 | is there a simple way to add that? If not, this will take me a bit to kae changes to the admin database
| |
| 09:14 | <mgariepy> yes there is how did you first add the option in the LTSP_CC ?
| |
| 09:15 | did you uses a python script ?
| |
| 09:15 | <_UsUrPeR_> no, I manually edited the postgres databse
| |
| 09:16 | <mgariepy> ok,
| |
| 09:16 | _UsUrPeR_, INSERT INTO attributesdef (name) VALUE ('LOCALDEV')
| |
| 09:17 | INSERT INTO attributesdef (name,attributetype) VALUES ('LOCALDEV','1');
| |
| 09:17 | <_UsUrPeR_> mgariepy: is there a script for this? If so, what is it?
| |
| 09:17 | <mgariepy> stephane made a script for this
| |
| 09:17 | <robehend1> shawnp0wers: I've found that with fat clients, things tend to just "work" easier. Kids are able to , say, plug in a webcam and have it work in cheese. same with scanners and such. also have less issues with speed, espicially with some java-based programs, like the PhET series for education.
| |
| 09:18 | <mgariepy> it's in ltsp-cluster-control bzr branch
| |
| 09:18 | but the 5 SQL lines a quite simple
| |
| 09:18 | <shawnp0wers> robehend1: Do you have a writeup of how you do it? You're making me more and more interested...
| |
| 09:18 | <mgariepy> i can give them to you
| |
| 09:18 | <robehend1> shawnp0wers: simple as day. just build a normal client, and attach the --fat-client operator. It's all scripted.
| |
| 09:19 | komunista has quit IRC | |
| 09:19 | <_UsUrPeR_> mgariepy: I would appreciate that
| |
| 09:19 | <shawnp0wers> OH, so using the LTSP "sub-system" for lack of a better word.
| |
| 09:19 | robehend1: I thought you built your own solution
| |
| 09:19 | <robehend1> shawnp0wers: I'd recommend also giving it a different name, like fati386, to help differentiate between your existing chroots. So the command would be "sudo ltsp-build-client --arch i386 --fat-client --chroot fati386"
| |
| 09:19 | komunista has joined #ltsp | |
| 09:19 | <shawnp0wers> cool, I'll have to try it… :)
| |
| 09:20 | <robehend1> oh, nope. i'm going off the work thats already done, since 5.2 came out.
| |
| 09:20 | one if the biggest benefits, at least to my users, was having the mime-types just work. click on a pdf download, it opens a pdf viewer, etc.
| |
| 09:20 | <mgariepy> _UsUrPeR_, first you add the attribute in the DB
| |
| 09:21 | you need how to connect to postgresql database first
| |
| 09:22 | _UsUrPeR_, just ping me when you are connected to your DB with psql
| |
| 09:23 | <_UsUrPeR_> ok, no problem

| 09:24 | <_UsUrPeR_> typically I create a file with something like this in it -- "INSERT INTO attributesdef (name, etc...)" into a file, then psql ltsp < add.sql
| |
| 09:25 | mgariepy: I am in psql though. go ahead with your instructions
| |
| 09:25 | <mgariepy> i would do like : psql -h localhost ltsp
| |
| 09:25 | ok :) perfect
| |
| 09:25 | komunista has quit IRC | |
| 09:25 | <mgariepy> first create the attribute LOCALDEV: INSERT INTO attributesdef (name) VALUE ('LOCALDEV');
| |
| 09:26 | then change the type of the attributes: INSERT INTO attributesdef (name,attributetype) VALUES ('LOCALDEV','1');
| |
| 09:27 | <_UsUrPeR_> mgariepy, ERROR: syntax error at or near "VALUE"
| |
| 09:28 | <mgariepy> INSERT INTO attributesdef (name,attributetype) VALUES ('LOCALDEV','1');

| |

| 09:30 | <mgariepy> SELECT id,name FROM attributesdef where name='LOCALDEV'

| |
| 09:32 | <mgariepy> ok, so set this to true and then restart your thin client
| |
| 09:32 | <_UsUrPeR_> mgariepy: ok, /var/cache/getltscfg-cluster shows LOCALDEV="TRUE" now along with the previous copied statements
| |
| 09:32 | <mgariepy> problably just logout and login would do.

| |

| |
| 09:38 | <_UsUrPeR_> mgariepy / Gadi: I rebooted the client. Do you think the app servers/cluster server need to be rebooted as well?

| 09:40 | <Gadi> _UsUrPeR_: is there a /var/run/ltspfs_fstab?

| 09:40 | on the client
| |

| |
| 09:42 | <Gadi> sounds like a server-side problem to me
| |
| 09:43 | firewall on the server?
| |
| 09:43 | I guess that wouldn't matter
| |
| 09:43 | hmm...
| |
| 09:44 | <_UsUrPeR_> mgariepy, replace it? should I download a replacement or just re-install a package?
| |

| |
| 09:49 | <_UsUrPeR_> mgariepy: ok, done.
| |

| 09:52 | <_UsUrPeR_> ok
| |
| 09:53 | <mgariepy> does the /tmp/ltspfsmounter.log contain somethings ?
| |
| 09:55 | <_UsUrPeR_> mgariepy, I am not seeing any output to the temp file. here's the information http://pastebin.com/QWbBFzSr
| |
| 09:56 | <mgariepy> hmm
| |
| 09:56 | weird
| |
| 09:57 | <_UsUrPeR_> indeed :/
| |
| 09:58 | * _UsUrPeR_ reboots client | |
| 09:58 | <_UsUrPeR_> I made the change on both app servers
| |
| 09:59 | <mgariepy> gadi any idea ?
| |
| 10:01 | Gadi _UsUrPeR_, i'm out of idea, udev works since /var/run/ltspfs_fstab is populated
| |
| 10:01 | but ltspfsmounter doesn't get mounted with the right options
| |
| 10:01 | <Gadi> on phone - but if the log exists and is empty that is more troublesome than if the log does not exist at all
| |
| 10:02 | <_UsUrPeR_> hwoop
| |
| 10:02 | hold. I just rebooted the client
| |
| 10:02 | and attempted to plug in again

| |
| 13:35 | <Appiah> dist and version?

| |
| 13:36 | yes
| |
| 13:36 | <Gadi> ls -l /dev/fuse
| |
| 13:37 | <Guest14144> according to Ubuntu Wiki DebugLocalDev it should show fuse is loaded
| |
| 13:38 | crw-rw-rw- 1 root fuse
| |
| 13:38 | <Appiah> ltspfs on the server and ltspsd(?!) in the chroot
| |
| 13:38 | <Gadi> fuse is no longer a modulee, but in-kernel
| |
| 13:38 | <Guest14144> how do i check?
| |
| 13:38 | <Gadi> user is in fuse group?
| |
| 13:38 | <Appiah> k
| |
| 13:39 | <Guest14144> root is member of fuse, yes
| |
| 13:39 | <Gadi> gack! don't log in as root
| |
| 13:39 | you logging in as root from the thin client?
| |
| 13:39 | <Guest14144> i just added a shell screen
| |
| 13:39 | to troubleshoot
| |
| 13:39 | default is root
| |
| 13:39 | <Gadi> oh
| |
| 13:39 | I meant in ldm
| |
| 13:39 | the user you use to log into the server
| |
| 13:39 | <Guest14144> no ldm, running rdesktop
| |
| 13:40 | <Gadi> should be a member of the fuse group
| |
| 13:40 | ah, well, you need to start with that info
| |
| 13:40 | :D
| |
| 13:40 | <Guest14144> i login as root on server
| |
| 13:40 | bad?
| |
| 13:40 | <Gadi> you are not logging into the server at all
| |
| 13:40 | if you run rdesktop as SCREEN_07
| |
| 13:40 | instead of ldm
| |
| 13:41 | <Guest14144> no running as SCREEN_02
| |
| 13:41 | make a difference?
| |
| 13:41 | <Gadi> can you paste your lts.conf?

| 13:46 | that's a : and a D

| |
| 13:46 | <Guest14144> lol
| |
| 13:46 | k
| |
| 13:46 | one sec
| |
| 13:46 | <Gadi> then do this:
| |
| 13:46 | sudo chroot /opt/ltsp/i386 apt-get install ltspfs
| |
| 13:47 | <highvoltage> looks like a smiley to me
| |
| 13:47 | <Gadi> sudo ltsp-update-image --arch i386
| |
| 13:47 | then, reboot the client
| |
| 13:47 | and you should have a "Drives" folder in Windows under My Computer
| |
| 13:48 | usb sticks will appear as folders under the Drives foler when inserted
| |
| 13:48 | and will disappear when removed
| |
| 13:49 | <Guest14144> ok updating
| |
| 13:50 | will give it a go... stay tune
| |
| 13:51 | Should i be using SCREEN_07 instead of SCREEN_02?
| |
| 13:51 | <Gadi> doesnt matter
| |
| 13:52 | as long as you know where you put it
| |
| 13:52 | :)
| |
| 13:52 | 2 means you use ctrl-alt-f2 to switch to it
| |
| 13:52 | if you have multiple screens
| |
| 13:52 | <Guest14144> your a genius...it works!!!
| |
| 13:52 | <Gadi> as opposed to ctrl-alt-f7
| |
| 13:52 | <Guest14144> couldn't find any docs to fix this
| |
| 13:52 | <Gadi> we like to keep as much undocumented as possible to frustrate users
| |
| 13:53 | blame the marketing department
| |
| 13:53 | :)
| |
| 13:53 | <Guest14144> i really appreciate your help. so it was only missing ltspfs on the client?
| |
| 13:53 | <Gadi> so, rdesktop runs locally on the client
| |
| 13:53 | <Guest14144> yes
| |
| 13:53 | <Gadi> and the client, by default, doesnt have any kind of automounter to manage mounting drives
| |
| 13:53 | <Guest14144> well the ltsp client
| |
| 13:53 | <Gadi> as the client has no desktop environment
| |
| 13:54 | so, since we use ltspfs as our network automounter for mounts from Linux to the client
| |
| 13:54 | <Guest14144> well i guess that step should be added in the documentation
| |
| 13:54 | :(
| |
| 13:54 | <Gadi> we thought it suitable to use ltspfs also to automount locally on the client for non-Linux sessions
| |
| 13:54 | <Guest14144> that's great, all is good now
| |
| 13:55 | <Gadi> but, since by default, EVERYONE uses LTSP to connect to Linux... :)
| |
| 13:55 | <Guest14144> you saved me a lot of troubleshooting time
| |
| 13:55 | * Gadi is being a bit facetious | |
| 13:55 | <Guest14144> thanks again
| |
| 13:55 | <Gadi> though nonetheless factually accurate
| |
| 13:55 | np
| |
| 13:55 | enjoy!
| |
| 13:56 | <Guest14144> should i see a folder for the cdrom in the Drives folder?
| |
| 13:57 | there is one for Floppy and usb but none for cdrom
| |
| 13:59 | <Gadi> only when you insert a CD
| |
| 14:00 | <Guest14144> Just discovered that

| 14:19 | <rpm_> Hi all, I have a strange issue, I am running ltsp-cluster on ubuntu 10.04.1 and when I have a new user login for the first time the gnome panel never loads. I have to open a terminal with ctrl+alt+t and then killall gnome-panel. once that is done the problem goes away. Does anyone have any ideas?
| |
| 14:21 | <Gadi> rpm_: are you using likewise to authenticate?
| |
| 14:21 | <rpm_> yes
| |
| 14:21 | <Gadi> I have been seeing the same thing!
| |
| 14:21 | <rpm_> that sucks!
| |
| 14:21 | <Gadi> yeah
| |
| 14:21 | I think it is a race condition
| |
| 14:21 | between gnome and likewise's mkhomedir equivalent
| |
| 14:22 | <rpm_> any ideas on how to fix it?
| |
| 14:23 | <Gadi> not yet - but if you find one I am very interested
| |
| 14:23 | :)
| |
| 14:24 | <rpm_> Didn't think so, bummer.
| |
| 14:24 | <Gadi> I can tell you it happens with likewise-open version 6, as well
| |
| 14:24 | so, upgrading doesnt help
| |
| 14:24 | (with that bug)
| |
| 14:24 | <rpm_> Have you tried CentrifyExpress?
| |
| 14:25 | I tried that initialy but didn't like the response time from there customer service so I went with likewise
| |
| 14:25 | Guest14144 has quit IRC | |
| 14:26 | <Gadi> I have not
| |
| 14:29 | Guest14144 has joined #ltsp | |
| 14:30 | <rpm_> I am gonna try contacting likewise and see if they can resolve the issue, I was in contact with Joshua M. from their support staff and he was very helpfull and even went as far as setting up a lab wiht ltsp to fix an issue I was having wher only 15 or so clients could log in. I will also try centrify in parallel to see if that just fixes the issue. Thanks, knowing that it is probably likewise helps alot.
| |
| 14:30 | Guest14144 is now known as ebelanger | |
| 14:33 | <Gadi> rpm_: was it a problem with lsassd hanging?
| |
| 14:34 | rpm_: I found that problem, too after 20 or so clients - upgraded to version 6 just today to see if that resolves the issue
| |
| 14:34 | <rpm_> don't known, he didn't specify what the actual issue was but was able to fix it.
| |
| 14:34 | <Gadi> what was the fix?
| |
| 14:35 | Guest14144 has joined #ltsp | |
| 14:36 | <rpm_> The latest version of likewise seemed to fix it. I have to run I'll be back later though. thanks again

| |
| 15:35 | would it be overkill to run LTSP in qemu to serve a PowerPC?
| |
| 15:36 | i have this nice 20" imac g5 i would like to give a second life
| |
| 15:37 | <alkisg> remote: you don't need to constantly run it in qemu
| |
| 15:37 | You just need a powerpc kernel + virtual disk (chroot)
| |
| 15:38 | So if you prepare such a kernel + disk in qemu or even in some real powerpc hardware, then you can just use them on an i386 machine without qemu
| |
| 15:41 | <remote> oh really this is great news
| |
| 15:42 | i worked with LTSP in 2002 i'm sure it changed a lot since

| |
| 16:14 | <NeonLicht> Is Ubuntu going back to NFS?
| |
| 16:16 | <remote> they're providing nbd-server with the ltsp package
| |
| 16:16 | why do you ask?
| |
| 16:17 | <NeonLicht> I'm curious. It's not that I ever plan to use it or anything. Just curious.
