| |
| 10:00 | so much for that idea
| |
| 10:01 | <vnc786> just to share : this is what i did to add libreoffice extension for all fat clients (instead of adding one extension per user) http://pastebin.com/fiskzWhL

| |
| 13:37 | <muppis> For scripting or something for more general?

| 13:58 | JuJuBee has joined IRC (JuJuBee!~mike_knic@24-148-112-102.ip.mhcable.com) | |
| 13:58 | <JuJuBee> What is the procedure for ltsp fat client users to change their login password? in terminal just use passwd or ssh to server then passwd?
| |
| 13:59 | <workingcats> not sure how you mean the question. basically i want the IP to automatically pick a default username for an unrelated system
| |
| 13:59 | naboo has left IRC (naboo!~naboo__@afla45.neoplus.adsl.tpnet.pl, Remote host closed the connection) | |
| 13:59 | <workingcats> e.g. if the IP is x.y.z.74 my app would use user74 as username
| |
| 14:00 | <muppis> workingcats, I meant it as do you just want to see it or do need it in some script?
| |
| 14:00 | Phantomas has left IRC (Phantomas!~Phantomas@ubuntu/member/phantomas, Read error: Connection reset by peer) | |
| 14:00 | <workingcats> muppis, i need it in a script that runs server-side (on the account of the logged in user)
| |
| 14:01 | oh and i just found it
| |
| 14:01 | <muppis> Good. :)
| |
| 14:01 | <workingcats> env variable LTSP_CLIENT. also, "env" prints out all env vars hehe
| |
| 14:02 | in case anyone else was wondering
| |
| 14:02 | <muppis> JuJuBee, I'm not used fat clients much, but afaik user needs to ssh to server to change it.
| |
| 14:02 | <JuJuBee> muppis: thanks. will try that
| |
| 14:09 | <Hyperbyte> Hi JuJuBee :)
| |
| 14:09 | <JuJuBee> Hey Hyperbyte
| |
| 14:09 | Hows tings
| |
| 14:09 | <Hyperbyte> My things are good. How are your things?
| |
| 14:10 | <JuJuBee> My things are marvelous
| |
| 14:10 | <Hyperbyte> :)
| |
| 14:10 | That's always good to hear.
| |
| 14:12 | <JuJuBee> Yep, a very successful school year with ltsp. Very happy with the results
| |
| 14:14 | <Hyperbyte> Good. :-)
| |
| 14:15 | I got to spend around 20k euros on new server and new printer this month. :)
| |
| 14:15 | naboo has joined IRC (naboo!~naboo__@user-188-33-65-64.play-internet.pl) | |
| 14:15 | <Hyperbyte> Which is... you know, always nice, since I'm the one buying, but not the one paying. :P
| |
| 14:17 | <JuJuBee> Lucky you....
| |
| 14:19 | <vmlintu> JuJuBee: do you use /etc/passwd or LDAP or something else to store your users and passwords?
| |
| 14:19 | <JuJuBee> just / etc / passwd
| |
| 14:19 | Ive never been able to get ldap working
| |
| 14:20 | <vmlintu> With LDAP you could change the passwords directly from fat clients, but with /etc/passwd and /etc/shadow you have to do it locally..
| |
| 14:20 | locally on the server that is
| |
| 14:21 | What problems did you have with ldap?
| |
| 14:21 | <JuJuBee> I don't mind using the ssh to server method... until I get ldap working
| |
| 14:21 | Was a couple years ago, so I don't recall
| |
| 14:21 | I need a good how-to
| |
| 14:22 | <vmlintu> Are you going to use ldap just for users or also something else?
| |
| 14:23 | <JuJuBee> Don't know, prolly just users
| |
| 14:23 | Haven't given much thought
| |
| 14:23 | <vmlintu> This is how I did it before: http://labs.opinsys.com/blog/2010/01/27/setting-up-openldap-on-ubuntu-10-04-alpha2/
| |
| 14:24 | Nowadays I'm using Puavo to manage users and devices, so it's different..

| 14:37 | ltspuser_22 has joined IRC (ltspuser_22!c31772ca@gateway/web/freenode/ip.195.23.114.202) | |
| 14:37 | <DJUnreal> JuJuBee: you could probably use NIS too
| |
| 14:37 | <ltspuser_22> Hi
| |
| 14:37 | <DJUnreal> and change passwords using yppasswd
| |
| 14:37 | <ltspuser_22> I need an advice
| |
| 14:37 | <DJUnreal> hey ltspuser_22
| |
| 14:37 | 'sup?
| |
| 14:37 | <anivair> Morning. I'm back again to try to finish off the only problem I think I have left on my new server: graphics gone bad.
| |
| 14:37 | I'm getting graphhics distortion on the old red disklessworkstations boxes.
| |
| 14:38 | it's all slanted and off kilter
| |
| 14:38 | <ltspuser_22> I need to do some tests to check how many ldm sessions my server can handle
| |
| 14:38 | is there any way to simulate a ldm session??
| |
| 14:38 | I only have 2 terminals...
| |
| 14:39 | <unkmar> ltsp-chroot install cups. Setup the printer in a client. Copy /etc/cups/printers.conf and /etc/ppd/* from client to /opt/ltsp/arch/etc/cups/ of LTSP server.
| |
| 14:39 | <||cw> anivair: crt sacreens?
| |
| 14:39 | screens...
| |
| 14:39 | <anivair> nope. lcd
| |
| 14:39 | <||cw> ltspuser_22: spin up some virtual machine clones?
| |
| 14:40 | does vbox do page sharing? if so you could get about 30 128MB vm's in 1GB ram
| |
| 14:42 | <ltspuser_22> how much bandwith a ldm session needs? (normal situation)
| |
| 14:42 | <||cw> docs say it does, to an extent http://docs.oracle.com/cd/E26217_01/E35769/html/virtualbox.html
| |
| 14:42 | <DJUnreal> ltspuser_22: install oracle virtualbox on a spare pc and hammer the hell out of the server with it :)
| |
| 14:42 | <anivair> there IS a difference in that the ones that are not working are using vga ports and the new one uses dvi by default. I'll have to bring it up in a bit and check a new thin client with an old port
| |
| 14:42 | <ltspuser_22> are you trying to say that I can run some VMs and boot with PXE??
| |
| 14:43 | <DJUnreal> yes
| |
| 14:43 | <jammcq1> ltspuser_22: LDM needs very little
| |
| 14:43 | <||cw> just an idle session? likely nearly nothing.
| |
| 14:43 | <DJUnreal> set your VMs to use a shared port
| |
| 14:43 | they'll emulate their own MAC addresses
| |
| 14:43 | <vmlintu> ltspuser_22: I've seen thin client sessions using 0.1 - 125Mbps of bandwidth depending on what the user does..
| |
| 14:43 | <jammcq1> it's the applications that you choose to run that will dictate how many users your server can handle
| |
| 14:43 | <DJUnreal> and request DHCP across the cable
| |
| 14:43 | <||cw> ltspuser_22: yes, vbox supports PXE booting in a vm, as long as you're using the bridged config and not the default NAT
| |
| 14:43 | <DJUnreal> fwiw... our kids tend to DESTROY our server just by running badly-coded flash games
| |
| 14:43 | <ltspuser_22> ok...
| |
| 14:43 | I will try
| |
| 14:44 | thks
| |
| 14:44 | <DJUnreal> ||cw: most of the configs (NAT excepted) allow PXE :)
| |
| 14:44 | <||cw> DJUnreal: flash does software rendering on the host anyway, instead of offloading that to the client graphics like normal movie playing can
| |
| 14:45 | DJUnreal: well, the options are nat, host only, and bridged. the only one that's going to boot from the lan's pxe is bridged

| |
| 14:50 | <alkisg> Hello
| |
| 14:51 | <ltspuser_22> vmlintu: are you saying that if I have a 100 Mbps ethernet card could not work only for 1 user? Because if a user can use 125Mbps in a ldm session....
| |
| 14:53 | <vmlintu> ltspuser_22: fullscreen youtube with flash uses that much
| |
| 14:53 | naboo has left IRC (naboo!~naboo__@user-31-175-144-54.play-internet.pl, Ping timeout: 248 seconds) | |
| 14:54 | <DJUnreal> and THAT is one of the reasons we block youtube at our events
| |
| 14:55 | <vmlintu> Last time I tested 10 thin clients running youtube used ~850Mbps

| 14:56 | <DJUnreal> aggregate NIC transfer rates to allow multiple gigabit sessions to each LTSP backend server
| |
| 14:56 | * DJUnreal can't see a reason that bonding wouldn't work with LTSP either - you just set the IP on bond0 instead of eth0/eth1 | |
| 14:56 | <||cw> yup.
| |
| 14:56 | <DJUnreal> and the OS handles the rest
| |
| 14:56 | <||cw> well, OS and switch
| |
| 14:57 | <ltspuser_22> ok
| |
| 14:57 | I understand
| |
| 14:57 | thank you
| |
| 14:57 | <DJUnreal> as far as i know, the switch doesn't care?
| |
| 14:57 | <vmlintu> so I wouldn't try running an ltsp server with 100 Mbps ports
| |
| 14:57 | <DJUnreal> you don't need to port-channel a pair of switchports to get a bond working
| |
| 14:57 | <||cw> if the switch and OS aren't configured for the same type of balancing, then only outgoing traffic from the server will get balanced
| |
| 14:58 | <DJUnreal> true... maybe port channelling is worth looking at too
| |
| 14:58 | <||cw> yeah the bond will work, but the switch will send all new connections to whichever port it last saw the MAC address on
| |
| 14:58 | * DJUnreal isn't gonna be using it in his environment lol | |
| 14:58 | <||cw> which might end up looking like it's balanced sometimes
| |
| 15:00 | pretty much all managed and semi-managed switches have some type of trunking. LACP is best, but even when not, the balance method should be documented somewhere (mac hash usually) and you can tell the bonding driver to do the same
| |
| 15:00 | <DJUnreal> once i get some higher-end servers... i'll be looking at that kinda stuff
| |
| 15:00 | my switches are awesome...
| |
| 15:00 | if you set up a port-channel on them
| |
| 15:00 | you can do src-ip
| |
| 15:00 | src-mac
| |
| 15:00 | dst-ip
| |
| 15:00 | dst-mac
| |
| 15:00 | <||cw> for a new server, just get a 10G card
| |
| 15:00 | <DJUnreal> src-dst-ip
| |
| 15:00 | src-dst-mac
| |
| 15:00 | <||cw> though then you need a switch too
| |
| 15:01 | <DJUnreal> haha... only if you have 10G switching infrastructure
| |
| 15:01 | * DJUnreal is on a budget of 0 here | |
| 15:04 | <||cw> then "high end" is kinda not gonna happen either?
| |
| 15:05 | <DJUnreal> HaHa
| |
| 15:05 | you'd be surprised
| |
| 15:05 | <workingcats> thanks from me too for that bonding advice, very good to know :)
| |
| 15:06 | <DJUnreal> the words "scouts" and "charity donation" tend to get you quite a lot of kit
| |
| 15:06 | looks like one of the guys i know may be able to blag me some brand new laptops from dell for free
| |
| 15:06 | * DJUnreal is also working on getting some UPS gear | |
| 15:06 | <DJUnreal> APC are very happy to donate, or so i'm told
| |
| 15:06 | mikkel has left IRC (mikkel!~mikkel@80-198-36-38-static.dk.customer.tdc.net, Quit: Leaving) | |
| 15:07 | <DJUnreal> and i've got enterprise class switching gear (and a current pile of 13 enterprise servers from 10 years ago that got decommed from a datacentre by my old company)
| |
| 15:09 | it's not what you know... it's who you know (and i may be getting satellite internet gear donated soon!!!)
| |
| 15:09 | * alkisg has successfully tried bonding with 4 nics on the ltsp server, and a cheap switch, using round-robin on the server side | |
| 15:09 | <||cw> huh, netgear has a 100/1G/10G 8 port switch for under $1000
| |
| 15:10 | XS708E
| |
| 15:10 | <DJUnreal> ||cw... I might try to get Cisco to donate us a Nexus 5k setup :P
| |
| 15:11 | <||cw> that'd be nice
| |
| 15:11 | * DJUnreal would love a nexus core and a bunch of FEX's | |
| 15:11 | <DJUnreal> or better still, the same thing on our boats... dual nexii stacked into one virtual switch with FEX's hanging off it
| |
| 15:12 | <alkisg> New DEs rely on opengl so they won't work over the network no matter its speed... so for higher budgets, fat clients may work best
| |
| 15:13 | <DJUnreal> DEs?
| |
| 15:14 | <alkisg> desktop environments, like gnome3
| |
| 15:14 | <DJUnreal> 'ah
| |
| 15:14 | 'we use LXDE
| |
| 15:14 | clean, simple, and 'just works'
| |
| 15:14 | <alkisg> LXDE is trying to get merged with razor-qt?
| |
| 15:15 | <DJUnreal> it is?
| |
| 15:16 | and alkisg: what are you referring to as a 'fat client'?
| |
| 15:16 | <alkisg> I think so... pcmanfm was rewritten in qt, and there was a very long mailing list thread about them joining forces
| |
| 15:16 | !fatclients
| |
| 15:16 | <ltsp> fatclients: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
| |
| 15:16 | <DJUnreal> as in... are you expecting to hand images to them from LTSP as normal? or effectively use them as workstations on a domain?
| |
| 15:17 | <alkisg> Netbooted from ltsp server, but using their own cpu+ram to run programs
| |
| 15:17 | anivair has left IRC (anivair!~joe@69.58.115.123, Quit: Leaving) | |
| 15:17 | <DJUnreal> right right
| |
| 15:18 | so kinda what i'm expecting to do once i get drivers etc sorted for the machines we have
| |
| 15:18 | * DJUnreal has a very mixed bunch of systems | |
| 15:18 | <DJUnreal> that's my next project once i get load balancing working
| |
| 15:18 | hand out amd64 images to capable clients
| |
| 15:18 | hand out images with the correct video drivers for the 20 different sodding video cards we have
| |
| 15:19 | * DJUnreal is assuming ltsp can be customised to do this, right? | |
| 15:19 | <alkisg> Sure, although usually 1 image is enough
| |
| 15:19 | <DJUnreal> one image with drivers for all the cards?
| |
| 15:19 | * DJUnreal will need two... one for amd64 and one for i386-only | |
| 15:19 | <DJUnreal> luckily... debian 7 supports multiarch as well
| |
| 15:20 | so the server running amd64 debian can run i386 packages nicely
| |
| 15:20 | <alkisg> The benefit of running 64 bit clients is sometimes negligible... i386+pae might be enough for all

| 15:21 | naboo has joined IRC (naboo!~naboo__@user-188-33-65-64.play-internet.pl) | |
| 15:21 | <DJUnreal> maybe... but the kids we have tend to suck the life out of the server
| |
| 15:22 | so if i'm switching local apps on
| |
| 15:22 | i want to make use of everything available
| |
| 15:23 | have i mentioned my project is a bleedin' nightmate?
| |
| 15:23 | <alkisg> Hehe, why so?
| |
| 15:23 | * DJUnreal never did get those baby thinclients working | |
| 15:23 | <DJUnreal> that's another challenge for another day
| |
| 15:23 | alkisg: i get upwards of 20 machines required as clients
| |
| 15:24 | * DJUnreal gets given random hardware with unknown specs half the time | |
| 15:24 | <DJUnreal> the servers we have are out of date and suffering badly, hence my current challenge being to configure load balancing
| |
| 15:24 | <alkisg> We've deployed ~500 schools here, with random hardware... yours sounds like a piece of cake :)
| |
| 15:24 | With < 500€ budget per school, most of them with < 100€
| |
| 15:24 | <DJUnreal> the admins i have that go to site with me are a complete bunch of muppets - one of them tried to restart his client a while back while testing, typed init 6 in a shell, and managed to take the core freakin' server down instead
| |
| 15:25 | oh, and we aren't a school... we're truly portable/mobile
| |
| 15:25 | so we turn up somewhere
| |
| 15:25 | set up a cafe for a weekend
| |
| 15:25 | then rip it apart and go home
| |
| 15:25 | wgreenhouse has joined IRC (wgreenhouse!~wgreenhou@fsf/member/wgreenhouse) | |
| 15:25 | <DJUnreal> the guys who want it running are expecting us to run things like openarena (with 3d rendering etc) on it
| |
| 15:25 | so i need to find a way to make the clients work with that nicely
| |
| 15:26 | <alkisg> We've done that in ~20 workshops in different cities, with random hardware... we didn't have any problems, we only brought our switches along
| |
| 15:26 | <DJUnreal> HeHe
| |
| 15:26 | the majority of the kids all load flash games
| |
| 15:26 | and when you get 20 sessions full of flash games... the server starts to suffer
| |
| 15:26 | <alkisg> That's where localapps and fat clients come in
| |
| 15:26 | !flash
| |
| 15:26 | <ltsp> flash: Yes, flash sucks. An HD full screen 30 fps video needs 2.5 Gbps bandwidth (1920×1080×4×30)! 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 http://linterna-magica.nongnu.org
| |
| 15:26 | <DJUnreal> indeed
| |
| 15:26 | that's what i'm starting to work

| 15:31 | wgreenhouse has joined IRC (wgreenhouse!~wgreenhou@fsf/member/wgreenhouse) | |
| 15:31 | <DJUnreal> so anyway... last night i installed ltsp-server on the second machine
| |
| 15:31 | guess it's just the lts.conf i need to tweak now
| |
| 15:31 | to assign some clients to each server
| |
| 15:31 | got NIS set up... got /opt/ltsp and /home shared as NFS mounts automounted on the second server
| |
| 15:31 | <alkisg> dhcpd.conf
| |
| 15:32 | <DJUnreal> yeah, i guess i need to tweak that too
| |
| 15:32 | question...
| |
| 15:32 | ltsp-build-client
| |
| 15:32 | <alkisg> Unless you only want to balance the session and not the nbd image serving
| |
| 15:32 | ltspuser_22 has left IRC (ltspuser_22!c31772ca@gateway/web/freenode/ip.195.23.114.202, Quit: Page closed) | |
| 15:32 | <DJUnreal> does that do anything other than just creating the client image?
| |
| 15:33 | <alkisg> It configures nbd too, and updates the kernels in the tftp dir
| |
| 15:33 | <DJUnreal> right
| |
| 15:33 | so if i'm happy to have the images handed out from my master server
| |
| 15:33 | and literally just want my secondary server to be an extra 'login node' as it were
| |
| 15:33 | i can just tweak lts.conf?
| |
| 15:33 | <alkisg> Then just play with LDM_SERVER in lts.conf, yeah
| |
| 15:33 | <DJUnreal> cool
| |
| 15:33 | * DJUnreal hasn't had issues with clients getting an image | |
| 15:34 | * DJUnreal has only suffered from server overload once the clients are booted | |
| 15:34 | <DJUnreal> i've given my two servers static IPs and linked them in the hosts files on both machines
| |
| 15:34 | <alkisg> Did you set LDM_DIRECTX=True?
| |
| 15:34 | <DJUnreal> NFS automounts are working, NIS is working
| |
| 15:34 | not started doing that yet... that's the next step
| |
| 15:34 | it's a fresh build because the last lot of builds i had were catastrophically flawed
| |
| 15:35 | * DJUnreal learned from that not to let his admins do his job... | |
| 15:35 | * DJUnreal is the architect | |
| 15:35 | <DJUnreal> the other guys are cable/reboot monkeys
| |
| 15:35 | and they made a right mess of the last server build
| |
| 15:36 | wgreenhouse has left IRC (wgreenhouse!~wgreenhou@fsf/member/wgreenhouse, Quit: ZNC - http://znc.in) | |
| 15:38 | <DJUnreal> but yeah
| |
| 15:38 | i shall be turning on local apps
| |
| 15:38 | and directx
| |
| 15:38 | wgreenhouse has joined IRC (wgreenhouse!~wgreenhou@fsf/member/wgreenhouse) | |
| 15:38 | <DJUnreal> and maybe even turning off encryption
| |
| 15:38 | as there's nothing secure going over the LAN
| |
| 15:38 | it's VLAN'd from the internet
| |
| 15:38 | twice
| |
| 15:38 | * DJUnreal has quite a good setup there... | |
| 15:39 | <DJUnreal> VLAN for filthy-internet
| |
| 15:39 | output from that goes to a filtering and firewalling router/server
| |
| 15:39 | output from there into clean-internet
| |
| 15:39 | which pipes into the ltsp front-end NICs
| |
| 15:39 | and output from the LTSP back-end NICs goes into trusted-backend VLAN
| |
| 15:40 | which /only/ contains thinclients
| |
| 15:40 | and fatclients
| |
| 15:40 | and idiots
| |
| 15:40 | but those come as standard
| |
| 15:41 | 3 VLANs, 3 DHCP scopes, two of which are under my control
| |
| 15:42 | the specific reason for a clean-internet VLAN is that we sometimes get asked to allow certain devices straight through our filtered feed to the net rather than managing them
| |
| 15:42 | like, for example, our localised wifi hotspot for the kids' phones etc

| 15:45 | <DJUnreal> Welcome Back alkisg1
| |
| 15:48 | <alkisg1> :) bad connection!
| |
| 15:50 | * DJUnreal gets the gaffa tape, superglue and soldering gear out | |
| 15:51 | * DJUnreal guesses you missed most of his setup info | |
| 15:51 | <alkisg1> Nah, I only got disconnected for a minute.... and it's all in the irclogs
| |
| 15:51 | * DJUnreal laughs | |
| 15:52 | <DJUnreal> but yeah... i don't think i've got any security issues to worry about if i turn off encryption
| |
| 15:52 | only issue i can potentially see is if i'm sharing /home from my master server... disk i/o may start to suffer at some point
| |
| 15:53 | but then... most of the stuff the kids do shouldn't need to write to /home anyway
| |
| 15:53 | not if it's web browsing
| |
| 15:53 | <||cw> async nfs works pretty well if data isn't mission critical
| |
| 15:53 | <DJUnreal> of course... once i eventually get a server upgrade
| |
| 15:54 | i'll either rsync the /home volumes across both sides
| |
| 15:54 | or stick a NAS in the mix
| |
| 15:54 | <||cw> ofcs/gfs?
| |
| 15:54 | <DJUnreal> and have that hooked up over quad gigabit connections
| |
| 15:54 | which, incidentally, will probably return the bottleneck to my NAS i/o

| 15:55 | <DJUnreal> but at that point, i'll run a large raid 0+1 anyway, and just have it running across lots of spindles
| |
| 15:56 | don't care about capacity particularly... but if the bottleneck starts to be disk i/o rather than LAN access, i just add more spindles and that sorts it (up to a point - i know about diminishing returns etc, but in the small-scale it'll be fine)
| |
| 15:57 | and hopefully by the time i start bottlenecking at i/o i'll be given some upgrades from U320 SCSI to SAS (ideally 6GB/sec SAS)

| |
| 15:59 | but they won't end up in my servers...
| |
| 15:59 | * DJUnreal smells a desktop upgrade if that happens | |
| 15:59 | <||cw> iops-wise, one ssd vs 6 sas
| |
| 15:59 | <DJUnreal> yeah
| |
| 15:59 | <||cw> so, it's already a better deal
| |
| 15:59 | <DJUnreal> hence why it'd end up in my desktop ;)
| |
| 15:59 | you think i'd sacrifice my gaming rig to boost server i/o for a cybercafe? :P
| |
| 16:01 | <||cw> if you're buying one, no, but if it's donated for the cafe...
| |
| 16:02 | <DJUnreal> HeHe true
| |
| 16:02 | * DJUnreal needs an infrastructure that can use it though | |
| 16:02 | <DJUnreal> all my servers are old SCSI behemoths atm
| |
| 16:08 | so yeah
| |
| 16:09 | when i get some donations
| |
| 16:09 | we'll be well away
| |
| 16:09 | tonight, though

| |
| 18:43 | [19:30] <DJUnreal> does the sub-section machine-specific setting override the default?

| 21:38 | <dawydiuk> I'm trying to tweak the desktop for client machines to add shortcuts and what not. It's kind of painful in that I'm not familiar where all the config files and syntax are for xfce4. Is there a better way to go about this?
| |
| 21:39 | More specifically I'm trying to install a theme(to make it look more windows'ish) and put some desktop icons on the desktop to run some windows programs
| |
| 21:39 | how do you guys go about this(command line on server...)?
| |
| 21:40 | I was hoping there was a way to boot into the image in a writeable way so I could set it up how I want, like mounting via nfs r/w
| |
| 21:41 | <DJUnreal> it all depends... your best bet is to google for an xfce setup tutorial - what you're looking at is the actual desktop environment per user rather than ltsp
| |
| 21:45 | <dawydiuk> the trouble I'm having is all the guides are for using a gui my clients that access the gui have a read only image so I can't do much with this approach. I'm currently digging through the /opt/ltsp/i386/home/__user__ /.config/ scripts trying to figure out how to configure things like I want but there doesn't seem to be much documentation on how to do things this way, everything is guy based
| |
| 21:46 | s/guy/gui/g
| |
| 21:46 | <DJUnreal> you /can/ log in to the gui on the server
| |
| 21:46 | configure it there as the user your clients will use
| |
| 21:46 | <dawydiuk> I think theres got to be a better way to do this
| |
| 21:46 | <DJUnreal> then log out again
| |
| 21:46 | <dawydiuk> ahhh
| |
| 21:46 | <DJUnreal> and once you set it up for one user
| |
| 21:46 | you can just copy the settings to other users
| |
| 21:46 | your read-only image for ltsp isn't the actual client image
| |
| 21:47 | it's just an image that says "now open a remote X session to the server" and takes everything from the server side
| |
| 21:47 | <dawydiuk> my server is command line only, but this might be a good reason to install gui
| |
| 21:47 | <DJUnreal> it can't be command line only if you can get a gui on the clients
| |
| 21:47 | you simply log into the server and run startx
| |
| 21:47 | <dawydiuk> hmm
| |
| 21:47 | let me try startx
| |
| 21:47 | <DJUnreal> and it should fire up your x session on the server locally
| |
| 21:48 | i'd be recommending doing this on a local console though, not on an ssh session
| |
| 21:50 | <dawydiuk> no luck on startx missing packages
| |
| 21:50 | <DJUnreal> try ctrl+alt+f7
| |
| 21:50 | see if that loads a gui
| |
| 21:51 | <dawydiuk> no luck
| |
| 21:51 | I installed the ubuntu server command line then added the ltsp-server package
| |
| 21:52 | <DJUnreal> do your clients actually go all the way through to a gui?
| |
| 21:52 | <dawydiuk> yep, but isn't that using a different root filesystem
| |
| 21:52 | in /opt/ltsp/i386 vs /
| |
| 21:52 | <DJUnreal> up to a point
| |
| 21:53 | however if you want to work with that filesystem
| |
| 21:53 | <dawydiuk> I guess your right I would have to have an x server running on the server
| |
| 21:53 | <DJUnreal> you can just chroot to it on the server
| |
| 21:53 | <dawydiuk> thats what I've been doing to tweak the config files, but it's taking a really long time as i have to update the image and see if my changes worked
| |
| 21:54 | I'm thinking apt-get ubuntu-desktop from my server should get the correct packages for startx to work. What do you think?
| |
| 21:54 | <DJUnreal> uhh... i wouldn't do that tbh
| |
| 21:54 | you want to run xfce4 right?
| |
| 21:54 | <dawydiuk> yep
| |
| 21:54 | <DJUnreal> apt-get install xfce4
| |
| 21:54 | and it'll sort the dependencies
| |
| 21:55 | <dawydiuk> good call
| |
| 21:55 | <DJUnreal> on our servers here (running debian)
| |
| 21:55 | although we have lxde installed
| |
| 21:55 | we never log in locally on the server
