| 12:48 | <Helenah> I can't figure out what "Error: unknown error in reply to NBD_OPT_GO: cannot continue" means.
| |
| 12:49 | I also don't have the netstat command on my server, and can't find a package for it meaning I'm not sure which port NBD is listening on. Something on Google suggested port 2000, however nbd-client, when I use it for debugging gives me "Connection Refused".
| |
| 12:50 | I was removing metacity packages, clearly this has removed some sort of LTSP dependancy.
| |
| 12:51 | However, when I checked what APT wanted to remove beforehand, I was pretty convinced it was only removing UI libraries and the likes.
| |
| 12:52 | Oh, and another note, I only made changes to the fat client chroot.
| |
| 12:59 | GodFather_ has left IRC (GodFather_!~rcc@2600:1007:b104:a30a:7d8c:48f4:4b89:81, Ping timeout: 264 seconds) | |
| 13:03 | <||cw> Helenah: net-tools
| |
| 13:03 | <Helenah> hmm
| |
| 13:03 | Thanks
| |
| 13:05 | Hmm, appears to be running on 9571 as a inetd service.
| |
| 13:05 | That's more helpful.
| |
| 13:09 | ||cw: How do I pass a password to nbd-client? "INIT_PASSWD bad"
| |
| 13:09 | GodFather_ has joined IRC (GodFather_!~rcc@2600:1007:b104:a30a:7d8c:48f4:4b89:81) | |
| 13:09 | <Helenah> I couldn't find an argument in the manpage.
| |
| 13:10 | <||cw> I've not dug that far in. sounds like the ltsp scripts/config in your fat client chroot is buggered.
| |
| 13:10 | <Helenah> o.o
| |
| 13:11 | Ubuntu APT always does crap like this to me.
| |
| 13:11 | I guess I'll probs be best regenning the chroot.
| |
| 13:11 | Can chroots be assigned to clients via lts.conf these days? I remember previously, I had to use DHCP servers.
| |
| 13:14 | <||cw> you do it in the pxe config
| |
| 13:19 | <Helenah> hmm
| |

| 13:59 | <Helenah> ||cw: Are there any guides on using the pxe config for this?
| |
| 14:03 | I can't for the life of me get ltsp-build-chroot to stop installing gnome bloat.
| |
| 14:04 | I know most of these packages aren't needed because I've purged them from chroots.
| |
| 14:06 | To me it's bloat, I use prefered alternatives to applications such as gnome-terminal.

| 14:08 | <Hyperbyte> Helenah, you can always chroot into the ltsp dir (ltsp-chroot command) and uninstall them
| |
| 14:09 | <Helenah> Hyperbyte: Not the point
| |
| 14:09 | It takes time away from more important things, when it's best to have the solution to not have these apps install in the first place.
| |
| 14:10 | <||cw> Helenah: http://manpages.ubuntu.com/manpages/bionic/man8/ltsp-build-client.8.html --exclude seems promising
| |
| 14:10 | <Helenah> hmm
| |
| 14:10 | GodFather__ has left IRC (GodFather__!~rcc@2600:1007:b104:a30a:7d8c:48f4:4b89:81, Ping timeout: 276 seconds) | |
| 14:11 | <||cw> it's a script though right? the source can reveal many secrets
| |
| 14:11 | <Helenah> ||cw: LTSP definately doesn't depend on a DE, right?
| |
| 14:12 | It is entirely down to the end user, am I correct?
| |
| 14:12 | <||cw> I'd expect fat client would imply a DE, thin client does not
| |
| 14:13 | <Helenah> What I was meaning to say was, it doesn't depend on the gnome DE, right?
| |
| 14:13 | It's just, LTSP can work with KDE which doesn't depend on gnome.
| |
| 14:14 | <||cw> I'd guess you could --exclude ubuntu-desktop and --early-packages whatever DE you want
| |
| 14:14 | <Helenah> So technically, I could do --exclude mate-desktop
| |
| 14:14 | ubuntu-desktop? Interesting
| |
| 14:16 | <||cw> ubuntu-desktop is the virual package that includes all the default ubuntu things. for my PC I tend to do a server iso install and then manually install cinnamon-desktop
| |
| 14:17 | I'd likely use something else for ltsp tho
| |
| 14:18 | <Helenah> Yeah, I did --early-packages mate-session-manager terminator i3-wm conky xkbset
| |
| 14:20 | <||cw> there is an ubuntu-mate-desktop package, but that's probably also more stuff than you need.
| |
| 14:22 | though might be easier to remove a few things from that one than you try to include all the stuff you need
| |
| 14:39 | GodFather__ has joined IRC (GodFather__!~rcc@96-92-43-9-static.hfc.comcastbusiness.net) | |
| 14:41 | <Helenah> :/
| |
| 14:42 | ||cw: Yeah, you've to kinda excludes a lot of packages...
| |
| 14:43 | It was still installing gnome-terminal and mate stuff which I don't need lol
| |
| 14:43 | so I added even more packages to the exclude
| |
| 14:43 | heh
| |
| 14:47 | Now it's installing things like caja.

| 15:37 | alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Quit: Leaving.) | |
| 15:42 | <||cw> Helenah: have you considered copying the main -desktop package, remove the stuff you specifically don't want, and making your own local apt repo to add?
| |
| 15:53 | alkisg has joined IRC (alkisg!bc043b10@ubuntu/member/alkisg) | |
| 15:56 | <alkisg> !nbd-client
| |
| 15:56 | <ltsp> nbd-client: To try mounting the NBD image from the client initramfs: nbd-client 192.168.67.1 -N /opt/ltsp/i386 /dev/nbd0
| |
| 15:57 | <alkisg> Helenah: you can use this command to test ^
| |
| 15:57 | nbd-server listens in the iana-assigned port 10809

| 17:01 | <Helenah> ||cw: I think I can sort out the bloat by adding more packages to the exclude argument, such as caja and plank. Almost cleaned it up.
| |
| 17:02 | And it would be better this way in terms of chroot deployment.
| |
| 17:04 | alkisg: What would be the best way to allocate chroots to specific clients without DHCP?
| |
| 17:04 | I'm using proxy-DHCP
| |
| 17:05 | ||cw mentioned the pxelinux config, however I can't seem to find anything regarding the IP/MAC addresses of specific clients.
| |
| 17:06 | As for now, I'm going to use nbd-client accordingly to your suggestions.
| |
| 17:09 | <||cw> pxelinux.cfg/, make a file with the mac address and it'll load that instead of the "default" file. I think you can do mac prefixes too, enable more logging in dnsmasq and it'll tell you what files it's looking forand
| |
| 17:11 | use the nbd-client for debugging, it's not a production solution
| |
| 17:25 | <alkisg> Helenah: in pxelinux.cfg/01-mac-address you can put nbd chroots per client, nbdroot=server-ip/nbdname
| |
| 17:27 | <Helenah> alkisg: So, that would be in the format of 00:00:00:00:00:00:00, or 00-00-00-00-00-00-00-00?
| |
| 17:28 | <alkisg> dashes, the second one
| |
| 17:28 | <Helenah> And why do the MAC address format look long? I may have added too many digits there.
| |
| 17:28 | Thanks
| |
| 17:28 | <alkisg> read the pxelinux wiki if you need examples
| |
| 17:28 | <Helenah> I had an idea it would be the second one.
| |
| 17:28 | I'll take a look now thanks once again
