| 04:22 | <vas> Hi
| |
| 04:23 | Can anyone tell me ltsp-pnp is possible in ubuntu version 16.04
| |
| 04:23 | And i am looking for using more softwares like freecad,aurdino and some other designing tools
| |
| 04:31 | <vagrantc> !ltsp-manager | echo vas
| |
| 04:31 | <ltsp> vas ltsp-manager: LTSP Manager is a GUI tool that makes LTSP maintenance easy. It's the recommended way to install LTSP in common setups. More info: http://wiki.ltsp.org/wiki/Ltsp-manager
| |
| 04:31 | <vagrantc> vas: that documents a frontend that should work
| |
| 04:33 | it should also be possible using the manual methods
| |
| 04:34 | you'll probably want to use the ppa:
| |
| 04:34 | !greek-schools-ppa | echo vas
| |
| 04:34 | <ltsp> vas greek-schools-ppa: https://launchpad.net/~ts.sch.gr/+archive/ppa/ supports LTS Ubuntu releases with newer LTSP versions, bug fixes etc
| |
| 04:41 | <vas> Thanks Vagrant..Lemem check and revert back to you if i have any concern
| |
| 04:41 | <vagrantc> just ask in the channel, i might not be around

| 07:22 | <JerryT> alkisg, that cause poor colors/resolution?
| |
| 07:23 | <alkisg> JerryT: no, that causes more color/resolution and it goes a bit slower
| |
| 07:23 | The default for thin clients is 16 bit, this forces 32 bit
| |
| 07:24 | <JerryT> Gotcha, I can't really tell right now cause I'm not in the office but judging by my laptop's camera the room lit up when I rebooted.
| |
| 07:24 | So I think that worked.
| |
| 07:25 | I'll know for sure in the morning when I get in.
| |
| 07:25 | <alkisg> JerryT: why are you forcing them to be thin clients instead of fat?
| |
| 07:25 | Doesn't fat mode work better for you?
| |
| 07:26 | <JerryT> Actually I want them to be FAT
| |
| 07:26 | But I had an issue with our voip software
| |
| 07:26 | <alkisg> (11:06:29 μμ) JerryT: It seems that the video is just an issue if we set FATCLIENT=False
| |
| 07:26 | <JerryT> Really wierd one
| |
| 07:26 | <alkisg> That makes them *thin*
| |
| 07:26 | Ah sorry
| |
| 07:26 | I didn't read your second sentence there :)
| |
| 07:27 | voip usually has issues in thin mode, so yeah that's rather strange
| |
| 07:27 | forum has left IRC (forum!~Thunderbi@193-80-178-210.adsl.highway.telekom.at, Quit: forum) | |
| 07:27 | <JerryT> Well the issue was it couldn't bind to a socket
| |
| 07:28 | And it also couldn't find system libraries.
| |
| 07:28 | <alkisg> You should troubleshoot those issues instead of forcing fat mode
| |
| 07:29 | <JerryT> Yah, I spent a couple days on google and what not but I couldn't find anything regarding it.
| |
| 07:29 | Felt like the only one that's ever experienced it, lol.
| |
| 07:30 | <alkisg> I don't remember you asking here or in the list about it...
| |
| 07:30 | <JerryT> True, I think I stumbled in here after I had given up on that.
| |
| 07:30 | I'll take a look real quick and see if remotely I can reproduce it.

| 07:43 | <max2206> Hi, I need your help
| |
| 07:44 | <alkisg> Hello max2206
| |
| 07:45 | <max2206> I install ltsp on ubuntu server 16.04 everything works except a thin client
| |
| 07:45 | <alkisg> What error message do you see?
| |
| 07:47 | max2206 has left IRC (max2206!8d6506cc@gateway/web/freenode/ip.141.101.6.204, Client Quit) | |
| 07:47 | max2206 has joined IRC (max2206!8d6506cc@gateway/web/freenode/ip.141.101.6.204) | |
| 07:50 | <max2206> error only in work nbd-server he write me "nbd_server Client is not authorized to access"
| |
| 07:51 | but I created file "/etc/ltsp/nbd-server.allow" ind insert ip and mask my network
| |
| 07:53 | <alkisg> Delete /etc/ltsp/nbd-server.allow and try again
| |
| 07:54 | Do other clients work?
| |
| 07:54 | By default, there is no ip checking
| |
| 07:57 | max2206_ has joined IRC (max2206_!42bb4c8f@gateway/web/freenode/ip.66.187.76.143) | |
| 07:57 | <max2206_> I remove file
| |
| 07:58 | but I not connect on freerdp to my server
| |
| 07:58 | <alkisg> Freerdp is not nbd
| |
| 07:58 | What is the error message?
| |
| 07:59 | <max2206_> only ndbserver error in syslog
| |
| 08:00 | Statler has joined IRC (Statler!~Georg@p5B30E83E.dip0.t-ipconnect.de) | |
| 08:00 | <JerryT> alkisg, when things are ran as a fat client how does that work? Is it almost like a liveCD?
| |
| 08:01 | <max2206_> yes, run lubuntu with mount home directory with server
| |
| 08:02 | <alkisg> max2206_: what is the error message on the client?
| |
| 08:03 | JerryT: yes, the root / comes from the server via nbd which is like booting from a usb disk, and then /home comes from the server via sshfs
| |
| 08:04 | <max2206_> rdesktop couldn't be found but I install him and write option to lts.conf
| |
| 08:08 | <alkisg> OK, so now do you see any error?
| |
| 08:10 | <JerryT> So any ideas why a user wouldn't be able to bind() to sockets?
| |
| 08:11 | <max2206_> on server only : Can't open authorization file /etc/ltsp/nbd-server.allow
| |
| 08:11 | <alkisg> JerryT: exact error messages please
| |
| 08:11 | max2206_, no, we need error messages or screenshots of the client
| |
| 08:11 | <max2206_> on client: rdesktop couldn't be found
| |
| 08:11 | <alkisg> max2206_: do other clients work?
| |
| 08:13 | <JerryT> single instance bind: : Operation not permitted
| |
| 08:13 | <alkisg> JerryT: which port? under 1024?
| |
| 08:14 | <max2206_> error on client:
| |
| 08:16 | <JerryT> alkisg would strace show that possibly?
| |
| 08:17 | <max2206_> rdesktop couldn't be found some destributions have now switched to xfreerdp instead of rdesctop you may want to change screen_xx entry to that instead
| |
| 08:18 | <alkisg> max2206_: you don't answer to questions... do other clients work?
| |
| 08:18 | JerryT: when you run it in a thin client, does it work without using sudo?
| |
| 08:18 | (or without prompting you for password...)
| |
| 08:19 | <max2206_> alkisg - sorry, no
| |
| 08:20 | <alkisg> max2206_: what is your SCREEN_ entry in lts.conf?
| |
| 08:21 | <JerryT> alkisg, yes
| |
| 08:21 | Without sudo
| |
| 08:22 | <max2206_> SCREEN_07=rdesktop
| |
| 08:23 | <alkisg> JerryT: so if you run this from a terminal on a fat client, that' s the only line that you see, single instance bind: : Operation not permitted ?
| |
| 08:24 | max2206_: and the rest of the rdesktop lines, the options etc
| |
| 08:24 | Just remove the password if you have one
| |
| 08:25 | JerryT: ah, a possibility is that it tries to create a socket inside sshfs instead of a real fs, and it fails
| |
| 08:25 | E.g. trying to create a socket under ~/
| |
| 08:25 | This isn't related to ports then
| |
| 08:25 | <JerryT> Ohhhhhhh
| |
| 08:25 | <alkisg> The workaround would be to divert it to a real file system like /run/user
| |
| 08:25 | <JerryT> YES
| |
| 08:26 | <alkisg> If you need professional help in troubleshooting this, ping me in PM, but it's not really ltsp related...
| |
| 08:26 | <JerryT> It's trying to create it in ~/.Zoiper/zoiper.socket
| |
| 08:26 | I see that now in the strace
| |
| 08:29 | Ok, thanks. I may take you up on that.
| |
| 08:29 | I'm probably going to get some sleep and regroup my head in the AM.
| |
| 08:30 | <alkisg> Cool
| |
| 08:42 | <max2206_> thin client work ) I write to lts.conf "SCREEN_07=xfreerdp"
| |
| 08:42 | <alkisg> Yes, that's the solution
| |
| 08:46 | <max2206_> but now I do not have the ability to boot a thick client
| |
| 08:47 | <alkisg> max2206_: it's difficult to communicate that way... put your lts.conf to pastebin if you want us to understand better.
| |
| 08:49 | <max2206_> my conf: [default] SCREEN_07=xfreerdp LOCALDEV=True MODULE_01 = usb-storage RDP_SERVER=192.168.100.1 RDP_OPTIONS="--ignore-certificate --no-nla -d GPRC -a 32 -f -x l"

| 08:51 | <alkisg> max2206_: how do you plan to use it as a fat client? with SCREEN_08=ldm?
| |
| 08:55 | <max2206_> I created images
| |
| 08:55 | ltsp-build-client --dist xenial --arch i386 --fat-client-desktop lubuntu-desktop
| |
| 08:58 | <alkisg> You can add SCREEN_08=ldm. This will allow you to press alt+ctrl+f8 to switch to ldm and login as a fat client

| 17:26 | <JerryT> The files in /run/user/ what happens to them on shutdown, etc?
| |
| 17:27 | <vagrantc> they're stored in ram, so when the power is removed, they're gone
| |
| 17:28 | which is the exact intention for all files in /run ... it's only supposed to be used for transient files for a "run"ning system

| 17:52 | <Psyco40> hi all
| |
| 17:53 | <alkisg> Hello
| |
| 17:53 | <Psyco40> i have a problem with thin/fat Client, after boot always say "a new version of the system is availabe, rebooting in 10 sec
| |
| 17:54 | <alkisg> That should happen when you run ltsp-update-image, not after client boot
| |
| 17:55 | Which distro/version?
| |
| 17:55 | <Psyco40> ltsp run on a 16.04 ubuntu server 64 bit
| |
| 17:56 | <alkisg> Do you have anything weird wrt nbd server?
| |
| 17:57 | <Psyco40> nope
| |
| 17:58 | <alkisg> dd if=/opt/ltsp/images/i386.img of=/dev/stdout bs=64 count=1 2> /dev/zero | sha1sum -
| |
| 17:58 | The code that checks that is in $CHROOT/usr/share/ldm/rc.d/I01-nbd-checkupdate
| |
| 17:59 | Compare the output of the above dd ^ with a similar dd from a client /dev/nbd0
| |
| 17:59 | If they're different, you have something weird in your nbd setup
| |
| 18:00 | If you want do just disable that behavior, put this in lts.conf: INIT_COMMAND_RM_NBD_UPDATE="rm -f /usr/share/ldm/rc.d/I01-nbd-checkupdate"
| |
| 18:01 | <Psyco40> they are different
| |
| 18:01 | <alkisg> You have root access on the client?
| |
| 18:01 | Doesn't it reboot?
| |
| 18:02 | dd if=/dev/nbd0 of=/dev/stdout bs=64 count=1 2> /dev/zero | sha1sum -
| |
| 18:02 | <Psyco40> yes, i have a root access and yes, the client reboot
| |
| 18:02 | <alkisg> You can get root access without the client rebooting if you put SCREEN_07=shell
| |
| 18:03 | <Psyco40> i nou, i have enable it
| |
| 18:28 | after reboot client and server, the output of dd if=/opt/ltsp/images/i386.img of=/dev/stdout bs=64 count=1 2> /dev/zero | sha1sum - is tha same, but nothing change, always "a new version of the system is availabe, rebooting in 10 sec"

| |
| 18:44 | It may be a problem with nbd kernel module that I reported a month ago
| |
| 18:47 | <Psyco40> i tried disabling it but, after login bring me back to login window
| |
| 18:48 | <alkisg> Erm, this is unrelated to nbd issues
| |
| 18:48 | Did it work before, or you never got it to work?
| |
| 18:49 | <Psyco40> only with fat client, with thin client it never work
| |
| 18:49 | Statler has left IRC (Statler!~Georg@gwrz3.lohn24.de, Remote host closed the connection) | |

| |
| 18:50 | *now
| |
| 18:50 | <Psyco40> before, now both the fat and thin client dont work
| |
| 18:52 | i have change this line in CMDLINE_LINUX_DEFAULT="init=/sbin/init-ltsp forcepae" to MDLINE_LINUX_DEFAULT="init=/sbin/init-ltsp quiet" in /opt/ltsp/i386/etc/ltsp/update-kernels.conf
| |
| 18:52 | lucascastro has joined IRC (lucascastro!~lucas@201.182.221.14) | |
| 18:53 | <Psyco40> before this, thin client dosent boot, only fat client
| |
| 18:53 | and i have add LTSP_FATCLIENT=False in lts.conf
| |
| 18:58 | <alkisg> Psyco40: which desktop environment?
| |
| 18:58 | opengl desktop environments have issues working over network
| |
| 18:59 | <Psyco40> unity
| |
| 19:01 | <alkisg> Yeah unity doesn't really work over the network
| |
| 19:02 | Go for mate if you want thins
| |
| 19:02 | It might be possible to get it to work but it'll be so slow it's not worth it
| |
| 19:03 | <Psyco40> ok i try
| |
| 19:03 | <alkisg> !ltsp-manager
| |
| 19:03 | <ltsp> ltsp-manager: LTSP Manager is a GUI tool that makes LTSP maintenance easy. It's the recommended way to install LTSP in common setups. More info: http://wiki.ltsp.org/wiki/Ltsp-manager
| |
| 19:03 | <alkisg> This is the recommented way to install ltsp, it includes a link to the ubuntu mate cd
| |
| 19:09 | Btw why thin clients? Too old hardware?
| |
| 19:10 | <Psyco40> pentium 3 or 4 with less the 512 mb ram
| |
| 19:10 | <alkisg> Well then avoid unity at all costs :)
| |
| 19:10 | Go for mate, that's what I'm using here with p3/p4
| |
| 19:10 | Although p4 with > 2GHz cpu is better off with 1 GB DDR-1 as a fat client
