| 09:36 | <alkisg> !print
| |
| 09:36 | <ltspbot> I do not know about 'print', but I do know about these similar topics: 'fatclient-printers', 'printer'
| |
| 09:36 | <alkisg> !fatclient-printers
| |
| 09:36 | <ltspbot> fatclient-printers: You can publish printers on your network so that fat clients see them, by launching "system-config-printer" and selecting Server → Settings → Publish shared printers connected to this system
| |
| 09:36 | <alkisg> !printer
| |
| 09:36 | <ltspbot> printer: Quick how-to: RCFILE_01="/usr/sbin/jetpipe /dev/usb/lp0 9100 &" in lts.conf, reboot client, then go to server's add printer dialog, and specify network printer → jetdirect → ltsp123.local

| 10:58 | <Torsten> Hi, I'm trying to run ltsp with a virtualbox-image. Although I installed ltsp inside the image,
| |
| 10:58 | I'm still getting a: "mounting dev/loop0 on run/initramfs/ltsp/0/looproot failed: No such device" -error during boot :(
| |
| 10:58 | Any ideas ?
| |
| 11:04 | where I can look for
| |
| 11:05 | <alkisg> Hi Torsten,
| |
| 11:06 | !boot
| |
| 11:06 | <ltspbot> I do not know about 'boot', but I do know about these similar topics: 'BOOTPROMPT_OPTS', 'boot-partition', 'bootfloppy', 'local-boot', 'panic-reboot'
| |
| 11:06 | <alkisg> !boot-partition
| |
| 11:06 | <ltspbot> boot-partition: If you're using a separate partition for /boot, you need to define it like e.g. "ltsp image /,,/boot,subdir=boot". See "man ltsp ipxe" for more on "advanced image sources".
| |
| 11:06 | <alkisg> Check that one
| |
| 11:17 | <Torsten> Hi alkisg, thanks for the reply
| |
| 11:17 | I just have one big partition - no seperate boot or var partions
| |
| 11:18 | <alkisg> Is it flat vmdk?
| |
| 11:18 | <Torsten> Yes
| |
| 11:19 | <alkisg> What's the output of: sudo fdisk -l path-to-vmdk
| |

| |
| 11:23 | <alkisg> It doesn't show up, add a space in front of the initial /

| |
| 11:25 | Hmm - ok
| |
| 11:30 | <alkisg> Torsten: that was it? just the symlink name?
| |
| 11:31 | <Torsten> Hmm -ok
| |
| 11:31 | I will trz
| |
| 11:32 | I will try
| |
| 11:33 | <alkisg> setxkbmap de ==> to restore the keyboard
| |
| 11:33 | <Torsten> should I update ltsp initrd as well
| |
| 11:33 | <alkisg> No need
| |
| 11:34 | <Torsten> ok I reboot the client then :)
| |
| 11:35 | Yes works now - thanx a lot :D
| |
| 11:35 | So it was just the image name ...
| |
| 11:36 | <alkisg> The symlink name, yeah. I'm not sure what command you were running though.
| |
| 11:36 | You can also run: ltsp image /path/to/vmdk, directly, without a symlink; but it's easier if the symlink is named /srv/ltsp/blah.img
| |
| 11:37 | <Torsten> Hmm, going through the install manual - but ok ... surely made a mistake there
| |
| 11:37 | Enjoy your nap :)
| |
| 11:38 | Thanx a lot (y)

| 12:47 | <seb87> Hello, so no diagram describing the client startup sequence.
| |
| 12:47 | Can you describe these steps to me?
| |
| 12:57 | <alkisg> seb87: no. But if you have a specific question, maybe we can answer it
| |
| 12:58 | In general, the ltsp client boot sequence is 95% the same as with any other linux computer, and 99% the same as any netbooted linux computer
| |
| 12:58 | So you should be able to find generic information online
| |
| 13:10 | <seb87> in fact I have to make a diagram describing the steps of the boot of a client starting from the ignition I up to the display
| |
| 13:15 | <alkisg> seb87, ok, then google "diagram for linux booted computers", good luck! Is it a homework?
| |
| 13:18 | <seb87> school work
| |
| 13:19 | <alkisg> Did they specifically ask for ltsp? Or for any netbooted computer? Or for any linux computer?
| |
| 13:19 | <seb87> specialy thin client on ltsp
| |
| 13:20 | <alkisg> Wow, weird :)
| |
| 13:21 | <seb87> I would tell my teacher
| |
| 13:21 | :)
| |
| 13:28 | <alkisg> Where is that, France?
| |
| 13:32 | <ogra> googling "netbooting linux diagram" shoudl find you a bunch of images to steal from
| |
| 13:37 | <alkisg> Essentially is: BIOS/UEFI > PXE > TFTP > KERNEL/INITRD > DHCP > NFS rootfs > authenticate with SSH > SSHFS /home
| |
| 13:37 | If you make a diagram with these, and google the meaning of the words, you should be good to go

| 13:55 | <ogra> yo highvoltage !
| |
| 13:55 | <highvoltage> o/
| |
| 13:56 | * ogra thinks the freenode disaster was the best thing that happened to IRC in a long time ... everything got more active all of a sudden 🙂 | |
| 13:57 | <ogra> (even though its a shame and all ... it really triggered revival)
| |
| 13:57 | <highvoltage> *nod*
| |
| 13:57 | although for the most part for me it ended up being s/irc.freenode.net/irc.libera.chat/g .irssi/config :)
| |
| 13:57 | <seb87> ok thank you
| |
| 13:58 | <ogra> yeah, similar here (just hexchat)
| |
| 13:59 | <seb87> ok thank you
| |
| 14:05 | it's correct this ? https://ptgmedia.pearsoncmg.com/images/chap10_9780132354134/elementLinks/hill_fig10-01.gif

| 14:49 | <alkisg> seb34: eh, not exactly accurate, maybe 70%
| |
| 14:54 | ogra, highvoltage, (hi btw!) I have the following issues with IRC, do you have any workarounds?
| |
| 14:54 | (1) popup notifications in xorg. I guess hexchat can do that, but what about irssi?
| |
| 14:54 | (2) to be able to chat from different devices without confusing the users with multiple usernames or connections/disconnections => I guess I'll need znc there?
| |
| 14:54 | (3) a decent android client; I tried yaaic but it doesn't handle wifi disconnections/reconnections gracefully
| |
| 14:54 | That's why I'm considering matrix... it's OK if we plan to completely move to matrix rooms, but as an IRC bridge, it's not that good
| |
| 14:55 | <ogra> i use bip for 2 (in fact i maintain a snap for this to protect my server ... it is called "ircproxy")
| |
| 14:55 | seb34 has left IRC (seb34!~seb@90.85.91.40, Ping timeout: 250 seconds) | |
| 14:56 | <ogra> i used to use AndIRC for 3 ... but have not touched that in 1-2y ... not sure how well it still works ... kiwiirc works well in mobile browsers though
| |
| 14:57 | for 1 i guess you could do something with libnotify-bin ... not using irssi here though
| |
| 15:01 | <alkisg> bip => thanks googling, kiwirc => nah I don't want to have to enter my username again and again every 5 minutes :D, libnotify-bin => meh, let's keep our coding time for the "serious" projects like ltsp, snap, debian etc :D
| |
| 15:02 | <highvoltage> matrix is quite good. I run irssi in tmux. and then juicessh from my phone so I don't have to change nicks. there's a plugin for irssi that can show pop-ups in your gui although I don't use it. not sure my setup is necessarilly best for you but irssi in tmux has been working for me for years
| |
| 15:03 | <ogra> alkisg, libnotify-bin -> ships the notify-send command ... not much to code here except some script fired by irssi on pings
| |
| 15:04 | <alkisg> Thank you guys, I'll do some reasearch and give it some more thought
| |
| 15:05 | <ogra> https://www.chiark.greenend.org.uk/~cjwatson/code/notifications/
| |
| 15:05 | actually even from colin !
| |
| 15:06 | heh "Last modified: $Date: 2008-05-06" ... perhaps not very recent anymore
| |
| 15:08 | <alkisg> For comparison, in matrix I just log in from the web ui from any device and it automatically syncs all the logs of my single account,
| |
| 15:08 | in Android I have the elementio application; the notifications work; and I can even go to settings and ask for an extra notification when anyone mentions alkisg or ltsp in any room
| |
| 15:08 | It would be nice if some protocols like IRC got upgraded periodically; like programming languages etc; or maybe it's indeed time to switch to something more recent...
| |
| 15:09 | <ogra> i thnik there was some work going on towards "IRC 3.0"

| 15:25 | <muhwalt> re: notifications. I have weechat running on a box @ home and I just SSH into it if I want to IRC. I've used pushover in the past to get mobile (android) notifications. There was a script for weechat.
| |
| 15:31 | <alkisg> Thank you muhwalt . The problem with ssh/tmux/screen is that it imposes a fixed layout of COLUMNSxROWS, which doesn't fit properly in all devices...
| |
| 15:31 | Meh maybe I'm just weird. I spend 90% of my time in a terminal, yet I do like to use proper GUIs in the rest of the time when I'm on IRC or browsing...

| 16:11 | <quinox> for what it's worth, I run weechat inside tmux over mosh; it resizes on-the-fly to fit all devices (smallest colxrows), if I am working on a big screen and I want weechat to be bigger I use tmux '^b D' to see the list of connections, and kick the other device that is limiting me

| 16:37 | <seb18> =(
| |
| 16:56 | the tftp is before the dhcp?
| |
| 17:00 | <alkisg> There are 2 dhcp, one before and one after tftp
| |
| 17:00 | First dhcp is from bios/pxe, second is from linux
| |
| 17:00 | <seb18> ok !
| |
| 17:04 | if i resume bios > pxe > dhcp > tftp > kernel / initrd > dhcp > nfs > authenticate machine with ssh > sshfs > login
| |
| 17:05 | it's correct or no ?

| 18:31 | <muhwalt> alkisg: I use tmux/weechat. Citrassh on android seems to work fine, re: columnsxrows
| |
| 18:32 | seems terminal dependant. I'm stuck using windows on my wrk laptop, and have had mixed experiences with putty and terminus
| |
| 18:32 | ...and git-bash
| |
| 18:50 | <alkisg> At least windows 10 have ssh built-in; that and realvnc is all I need to reach my work pc :)
| |
| 18:54 | !learn windows-ltsp-ccboot as TODO: check https://www.ccboot.com and icafe8, they seem a bit similar to LTSP but for Windows
| |
| 18:54 | <ltspbot> The operation succeeded.
