| 02:08 | <map7> Hi I'm trying to setup LTSP to PXE boot over http to a remote LTSP server (using a chroot image) under Debian Bullseye and I've got a 'mount' issue during boot
| |
| 02:08 | https://ibb.co/pQ86rtG
| |
| 02:09 | That's a picture of the error
| |
| 02:09 | mount: No such file or directory
| |
| 02:17 | When I can /proc/cmdline I can see nfsroot has the wrong IP, how do I set this?
| |
| 02:34 | I added 'set srv [ip address]' to my ltsp.ipxe, but I still have an issue with /scripts/init-bottom/ltsp-initrd-bottom: Permission denied
| |
| 03:24 | I've just setup a new LTSP server on my local network setup with the same proceedure and get the same error. I must be doing something wrong.

| 04:28 | <alkisg> map7: can you upload a screenshot of the new error message?
| |
| 04:34 | <map7> alkisg: I just got it all working :)
| |
| 04:34 | Just then would you believe it
| |
| 04:34 | <alkisg> 👍
| |
| 04:35 | <map7> So I can now boot my diskless machines using PXE to a remote server in a VPS
| |
| 04:35 | over http
| |
| 04:35 | Using real thinclients
| |
| 04:35 | (Had to build a custom iPXE file)
| |
| 04:36 | Finally I can get rid of all hardware at work and live the dream!
| |
| 05:25 | <alkisg> Haha, is it fast enough over VPS?
| |
| 05:26 | * alkisg doesn't understand that use case though, an ltsp server is essentially a file server, it's much faster and cheaper to have a local file server than a remote one... | |

| 08:40 | <nikoh77[m]> hello, good morning, I would like to use the directive "POST_INIT_SERVICE" (actually alkisg suggested it to me) to start a service only on clients; the question is: on the server can I "disable" it or just stop it?
| |
| 08:42 | antaresgades has joined IRC (antaresgades!~antaresga@ieocadiz.cd.ieo.es) | |
| 08:45 | <alkisg> nikoh77: on the server you can either disable it or stop it, whatever you prefer
| |
| 08:57 | <nikoh77[m]> <alkisg> "nikoh77: on the server you can..." <- on client booting...: "LTSP command failed: eval systemctl restart my.service aborting ltsp"
| |
| 08:57 | <alkisg> Boot the client normally. Then run `sudo systemctl restart my.service`. Does that succeed?
| |
| 08:58 | If not, you'll need to troubleshoot why the service doesn't start
| |
| 08:58 | E.g. maybe it relies on stuff that you have on your server, that are not published in the image?
| |
| 08:58 | <nikoh77[m]> must I rebulid image after disabled the service on server?
| |
| 09:01 | <alkisg> You shouldn't need to; systemctl restart service works whether it's initially disabled or enabled
| |
| 09:04 | <nikoh77[m]> <alkisg> "Boot the client normally. Then..." <- in my service there is "After = network.target", could it be that the post_init_service loading happens too soon?
| |
| 09:05 | <alkisg> Did I write POST_INIT_SERVICE? I meant POST_SERVICE_X="..."
| |
| 09:05 | POST_SERVICE runs when systemd etc is up; POST_INIT_x runs before it's up
| |
| 09:06 | You can also enable it like this:
| |
| 09:07 | POST_INIT_ENABLE_MY_SERVICE="systemctl enable --quiet --root=/ --no-reload my.service"
| |
| 09:07 | This tells systemd to enable that service very early on boot, even before systemd is loaded, and later on, when it's loaded, it'll start it
| |
| 09:12 | <nikoh77[m]> ok so i try with POST_SERVICE_X
| |
| 09:12 | just one doubt: X do I have to replace it with something or do I leave it like this?
| |
| 09:12 | <alkisg> You replace it with a name. Try POST_INIT_ENABLE_MY_SERVICE instead, it's better.
| |
| 09:13 | As it takes effect even before systemd loads
| |
| 09:30 | <nikoh77[m]> YEAH it work, thanks a lot ;-)

| 13:09 | <antaresgades> Hello. Regarding to administrative raspberry pi's... It is supposed to be sufficient to put inside ltsp.conf the MAC of the PI in ADMINISTRATIVE_CLIENT=[MAC] and then initrd and reboot client, isn't it?
| |
| 13:51 | Well, I finally managed to fix it (just messing with the wrong ltsp.conf file). But I have an issue. I am able to login with he pi user but even with sudo I cant apt-get or whatever (permission denied). I created a new LTSP installation and copied a raspios chroot from another machine. Clients work ok, but I am not able to apt-get, etc
| |
| 13:51 | even with the administrative cliente
| |
| 13:52 | in fact with sudo su I see root@raspberry but it says "Unable to acquire the dpkg frontend, are you root?

| |
| 17:36 | <MUHWALT> Hey everyone. Maybe this is premature, but what is the 22.04 situation looking like with LTSP? Has there been any pre-release testing?
| |
| 17:37 | <alkisg> Hi MUHWALT, as usual I tested everything and released a new 22.01 LTSP in January
| |
| 17:37 | It went to Debian and from there to Ubuntu 22.04 and I've been using it since, with no known issues
| |
| 17:37 | If you see any issues, ping...
| |
| 17:37 | <MUHWALT> Fantastic, thanks! I finally hired a minion, which is freeing up my time for these larger projects :D
| |
| 17:37 | such as finally getting rid of LTSP5
| |
| 17:37 | * alkisg wish he had a million minions :D | |
