| 06:49 | <alkisg> Happy new year to everyone
| |
| 06:53 | Ark74 has joined IRC (Ark74!~Luis@177.246.232.49) | |
| 07:00 | <alkisg> Maijin: as Hyperbyte said, ask your question and wait for an answer. If you don't ask it first, how can we answer?
| |
| 07:01 | Ark74: if that thing can't pxe boot, it's possible to put the kernel+initrd locally
| |
| 07:01 | Since a couple of months ago, ltsp supports auto-updating a local kernel+initrd copy
| |
| 07:03 | <Ark74> alkisg, the info i could get from the device, is a NAND flash storage with a arm1176zfj processor
| |
| 07:03 | <alkisg> Can it boot linux?
| |
| 07:06 | <Ark74> i really can't boot anything yet, it boots WinCE 6
| |
| 07:06 | so i'm looking, maybe i can flash it with uboot
| |
| 07:06 | <alkisg> If you can't get it to boot linux, and you need a linux session, then just use rdp/vnc to connect to a server
| |
| 07:07 | How much ram does that have?
| |
| 07:07 | <Ark74> 128MB
| |
| 07:07 | <alkisg> Is that RAM or DOM (disk)?
| |
| 07:07 | teknkik has left IRC (teknkik!tek@kapsi.fi, Ping timeout: 276 seconds) | |
| 07:07 | <alkisg> Usually wince devices are so low spec'ed that they're not worth the trouble to make them ltsp clients
| |
| 07:08 | <Ark74> http://www.sharethinclient.com/products_show_6.html
| |
| 07:09 | <alkisg> So both RAM and DOM are 128MB...
| |
| 07:09 | <Ark74> yep
| |
| 07:10 | so, i can use rpd to boot the LTSP session?
| |
| 07:10 | <alkisg> No, but you can use rdp to connect to the ltsp server
| |
| 07:10 | <Ark74> *rdp
| |
| 07:10 | <alkisg> Although that's not related to ltsp of course, it's just rdp
| |
| 07:10 | rdp can be used to connect either to windows pcs, or to linux pcs that have xrdp installed
| |
| 07:12 | <Ark74> ohh, that's something new, a xrdp and a x over ssh is the same?
| |
| 07:12 | <alkisg> rdp is a windows protocol
| |
| 07:12 | X is a linux protocol
| |
| 07:12 | xrdp is an rdp server that runs on a linux machine
| |
| 07:12 | So yes it's very different from x over ssh
| |
| 07:13 | <Ark74> ok, also, you can boot a machine directly to a rdp session, right?
| |
| 07:13 | or can you?
| |
| 07:13 | <alkisg> rdp is an application like a calculator or an editor or vnc
| |
| 07:13 | You first boot the computer to any OS, then run the rdp application
| |
| 07:14 | In your case, you boot to wince, and run the rdp client from there
| |
| 07:14 | If you want to autorun the rdp client, you can configure that inside wince like all other apps
| |
| 07:14 | <Ark74> so is like the vnc to gnu/linux, then rdp to windows?
| |
| 07:15 | <alkisg> There are clients and servers for both vnc and rdp, for all OSes
| |
| 07:15 | <Ark74> a ltsp server has xrdp installed?
| |
| 07:15 | <alkisg> So you can rdp from windows to linux, or vnc from windows to windows, etc etc, any combination
| |
| 07:15 | You can install xrdp to any linux distro. No, it's not preinstalled, but you can install it.
| |
| 07:16 | All these things are not related to ltsp. You can install rdp to an ltsp server, or you can install it to a linux machine that doesn't have ltsp, whatever you want.
| |
| 07:16 | <Ark74> ok, it's just that i read somewhere that rdp is supported on ltsp, or maybe a rdp session login
| |
| 07:17 | <alkisg> That the opposite of what you want
| |
| 07:17 | That is about booting an ltsp client, and then using the display manager (LDM) to connect via the xfreerdp client to a windows server
| |
| 07:18 | <Ark74> xDD
| |
| 07:18 | hehehe
| |
| 07:18 | <alkisg> You don't have an ltsp client in this case, you just want to use the rdp application
| |
| 07:18 | (or the vnc application)
| |
| 07:18 | <Ark74> ok, thanks
| |
| 07:19 | <alkisg> Note that the client specs are too low, so you'll get better performance from a 15 year old p4
| |
| 07:19 | You're welcome
| |
| 07:19 | <Ark74> you mention a really good point, i don't know if it's worth it to mess around and try to flash this thin client
| |
| 07:19 | <alkisg> You don't need to flash it to use rdp
| |
| 07:19 | It's already installed in wince
| |
| 07:19 | <Ark74> to get pxe
| |
| 07:20 | <alkisg> Yup, it's not worth to get uboot etc running on that
| |
| 07:20 | <Ark74> so it boots directly
| |
| 07:21 | thanks alkisg i get the clear picture now
| |
| 07:21 | <alkisg> :)
| |
| 07:21 | <Ark74> \o/!

| 07:41 | <alkisg> Happy new year vagrantc
| |
| 07:42 | NeonLicht has joined IRC (NeonLicht!~NeonLicht@darwin.ugr.es) | |
| 07:43 | <vagrantc> alkisg: indeed!
| |
| 07:43 | alkisg: happy new year to the likes of you!
| |
| 07:43 | <alkisg> Let 2016 bring ltsp6
| |
| 07:43 | <vagrantc> there is a certain logic there
| |
| 07:44 | introduced ltsp5 in 2005, ltsp6 in 2016... :)
| |
| 07:44 | (although it was muekow in 2005...)
| |
| 07:45 | * alkisg would like to hear the story behind the muekow name... | |
| 07:45 | <vagrantc> first version i see called ltsp5 wasn't until 2007
| |
| 07:46 | <alkisg> As for the name MueKow, it was part of an inside joke between sbalneav and myself. Somehow, the name stuck. If the experiment works out, this will likely become LTSP-5.0. -- JimMcQuillan - 28 Feb 2005
| |
| 07:46 | <vagrantc> right
| |
| 07:46 | <alkisg> sbalneav: so, what was the inside joke?! :)
| |
| 07:47 | * vagrantc vaguely recalls something about "longhorn was already taken" | |
| 07:47 | <alkisg> Hehe

| |
| 13:52 | Hyperbyte: as well

| 14:14 | quinox has joined IRC (quinox!~quinox@ghost.qtea.nl) | |
| 14:35 | <alkisg> Meh. /usr/share/initramfs-tools/hooks/intel_microcode puts GenuineIntel.bin to the initramfs, tailored to the *current system*. That doesn't sound good for booting e.g. amd clients from an intel server...
| |
| 14:36 | NeonLicht has left IRC (NeonLicht!~NeonLicht@darwin.ugr.es, Ping timeout: 250 seconds) | |
| 14:40 | <alkisg> The whole intel blob is 744740 bytes, quite big to include it in the initramfs by default...
| |
| 14:41 | If needed, we can do it from /etc/default/intel-microcode
| |
| 14:42 | IUCODE_TOOL_SCANCPUS=yes
| |
| 15:08 | <quinox> https://ghost.qtea.nl/tmp/virtual_ltsp_boot_via_qemu.mp4 booting LTSP via PXE via QEMU works just fine
| |
| 15:11 | it currently boots off our real LTSP server; next steps are to use the auto-login feature of LDM to login+screenshot+shutdown without manual interaction, put the LTSP server itself inside docker or something and get QEMU to boot from the docker image
| |
| 15:13 | once that step is achieved it should be fairly easy to automatically test if <your-OS-choice> can run LTSP
| |
| 15:15 | boot from the docker image --> boot via PXE using the services inside the docker image
| |
| 15:15 | and apparently I'm missing "/etc/ltsp/ntpupdate" inside my client image, I never noticed that error before
| |
| 15:22 | https://ghost.qtea.nl/tmp/qemu-0650.jpeg <-- the error is the 7th line from the bottom... I suppose "/etc/rc.local: 27:" refers to line 27 of rc.local, but that one just contains "exit 0"

| 18:02 | <alkisg> quinox: I don't think /etc/ltsp/ntpdate exists in LTSP, it sounds like a local thing in your installation

| 21:27 | vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc) | |
| 21:34 | <quinox> might be, although I know we use -s inside /etc/default/openntpdate for that as well
| |
| 21:35 | * quinox will track it down somehow | |
| 21:42 | <quinox> yeah it's a RCFILE_01, it's surrounded by LOCAL_APPS and we switched to fat clients many years ago already so it's probably an ancient entry
