| 13:14 | <markit> hi alkisg :) I'm planning to try ltsp in 18.04 (Kubuntu), is it stable / works fine? There are a lot of "bad" things there, like systemd-resolver and netplan I guess
| |
| 13:15 | btw, is it me, or the more Ubuntu "advances" and the harder becomes the network setup? Long time ago was just a matter of 2 files, /etc/network/iterfaces and /etc/resolv, now is a mess :(
| |
| 13:32 | <alkisg> markit: ltsp works fine here in mate 18.04
| |
| 13:32 | I haven't tested kubuntu
| |
| 13:32 | Use network manager to set up networing
| |
| 13:32 | Via gui
| |
| 13:33 | <markit> alkisg: -pnp too? Just an apt install or do I have to run some script to "fix" configurations?
| |
| 13:33 | <alkisg> apt install
| |
| 13:33 | !install
| |
| 13:33 | <ltsp> install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
| |
| 13:33 | <markit> (long time I've no installed ltsp nor updated)
| |
| 13:35 | I've 2 installations with a bridge on the client side in /etc/network/interfaces, 14.04 version, is that file still relevant or I have to fight with netplan or ltsp wants networkmanager (that I avoided to prevent teacher to mess things up)?
| |
| 13:39 | <alkisg> there was not change in ltsp wrt networking
| |
| 13:39 | The only new thing is `ltsp-config dnsmasq --enable-dns` if you want a dns server
| |
| 13:40 | <markit> so tftpd-hpa/isc-dhcp-server is deprecated / better remove it and go to dnsmasq, correct?
| |
| 13:41 | <alkisg> well, dnsmasq is just easier so we default to that
| |
| 13:41 | as it supports proxydhcp too
| |
| 13:42 | but if you want to use the others, you sure can
| |
| 13:42 | Btw you can easily prevent the teacher from changing connections with network manager
| |
| 13:42 | <markit> finally, do you suggest remove ltsp packages, upgrade 14.04 -> 16.04, then -> 18.04, reinstall ltsp and reconfigure? backup and restore data + users + whatever to a new 18.04 scares me
| |
| 13:42 | <alkisg> Either don't make him sudoer, or edit the policy kit configuration
| |
| 13:42 | I've no idea about kubuntu migration
| |
| 13:43 | The upgrade is scary when the desktop environment has setting upgrades
| |
| 13:43 | <markit> never messed with policy kit ;P
| |
| 13:43 | <alkisg> I don't know kubuntu settings, so I can't comment
| |
| 13:46 | <markit> I've to leave, thanks a lot as usual, see you later, I want also to know how your life is going and how greek's schools are moving

| 15:25 | <mwalters> http://wiki.ltsp.org/wiki/Ltsp-manager/Netboot_clients < Is the bit about UEFI not being supported still accurate?
| |
| 15:35 | <||cw> mwalters: should just be a matter of put the signed grub uefi file in place and pointing the dhcp settings to it
| |
| 15:35 | I've not tried though, and ltsp doesn't do it for you in any way
| |
| 15:36 | see https://wiki.ubuntu.com/UEFI/PXE-netboot-install and https://wiki.ubuntu.com/UEFI/SecureBoot/PXE-IPv6?action=show&redirect=UEFI%2FSecureBoot-PXE-IPv6
| |
| 15:44 | <mwalters> ||cw: thanks, I'll check it out
| |
| 18:11 | alright, I got the uefi client booting a signed grub img... doesn't seem to be loading grub.conf, though
| |
| 18:15 | <alkisg> mwalters: you can enable tftp logging to see which files the client tries to access
| |
| 18:15 | E.g. it might be searching in a wrong path
| |
| 18:16 | What are you using, dnsmasq, isc-dhcp, tftpd-hpa?
| |
| 18:18 | <mwalters> isc-dhcp
| |
| 18:20 | looks like logging is already on, taking a look now
| |
| 19:02 | til: grub looks for grub.cfg, not grub.conf.
| |
| 19:14 | aw yiss, got it working. Thanks everyone. I was making way harder in my head than it really was
| |
| 19:25 | hrm, tge yefu ckuebt seens ti taje firever ti biit cinoared ti tge regular pxelinux clients
| |
| 19:25 | oops
| |
| 19:25 | the uefi client seems to take considerably longer
| |
| 19:25 | to boot
| |
| 19:44 | <alkisg> mwalters: can you pastebin your config somewhere?
| |
| 19:45 | <mwalters> the grub config?
| |
| 19:45 | <alkisg> grub and isc-dhcp, for reference
| |
| 19:45 | In case others want to try out uefi
| |
| 19:45 | <mwalters> grub loads quick, after pulling vmlinuz and initrd.img things take 5eva
| |
| 19:45 | <alkisg> I've tested it in the past, but it's been 3 years now, so my tests are stale...
| |
| 19:45 | <mwalters> lemme see what I can do
| |
| 19:46 | <alkisg> *after* vmlinuz and initrd? It would be strange for the kernel to be slower in uefi...
| |
| 19:46 | <mwalters> yeah, it's odd
| |
| 19:46 | <alkisg> If you were saying "downloading initrd takes minutes", I wouldn't be surprised, but now... hm...
| |
| 19:46 | <mwalters> server/chroot is 14.04, though... and I'm getting stuck at 800x600 on this thing once all loaded up... I'm suspecting I'm having module issues
| |
| 19:46 | could be that's downloading initrd
| |
| 19:47 | I just saw the req in syslog
| |
| 19:47 | after that req it's slow
| |
| 19:47 | this is a newer intel nuc
| |
| 19:47 | <alkisg> I think ipxe is much faster wrt networking than grub
| |
| 19:48 | <mwalters> maybe, this seemed like the path of least resistance, though ;)
| |
| 19:49 | https://pastebin.com/PGsZt83H grub.cfg
| |
| 19:49 | most of the gfx stuff is me goofing around
| |
| 19:49 | <alkisg> Btw, once the client boots, does `dmesg` show a small boot time like 20 secs, or the big one like 2 minutes?
| |
| 19:51 | <mwalters> https://pastebin.com/BHfFzJB1 relevant parts of dhcpd.conf?
| |
| 19:52 | let me check
| |
| 19:53 | what am I looking for in dmesg?
| |
| 19:54 | assuming this should be run from a vterm on the client?
| |
| 19:57 | final stamp in dmesg is 300
| |
| 19:57 | the stamp immediately preceeding is 11
| |
| 19:59 | the few entries prior to the long wait: "nbd9: unknown partition table", "nbd9: NBD_DISCONNECT", "nbd9: Receive control failed (result -32)", "NBD9: queue cleared"
| |
| 19:59 | the the final entry is "MCE: [hardware error]: Machine check events logged"
| |
| 20:03 | ok, the 300 is something else... dmesg shows 11s
| |
| 20:04 | when run right after booting
| |
| 20:04 | so might just be initrd taking forever
| |
| 20:05 | https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1514038 possibly this
| |
| 20:12 | <alkisg> mwalters: try a newer grub from bionic
| |
| 20:13 | (although it says fix released for trusty...)

| |
| 20:19 | just as fast as the legacy clients now
