| 07:50 | <vagrantc> alkisg: just to be clear, my pull request was different than the patch in the bug ... not sure which you tried
| |
| 07:51 | alkisg: regarding epoptes...
| |
| 07:51 | <alkisg> vagrantc: ah, sorry, let me check again
| |
| 07:52 | vagrantc: indeed, I only tested the patch in the bug, sorry about that
| |
| 07:52 | I committed a fix already, is it ok that I didn't merge even though it's pretty much the same?
| |
| 07:52 | <vagrantc> heh
| |
| 07:52 | <alkisg> I can re-push :)
| |
| 07:53 | <vagrantc> of course it's fine ... important thing is to get it fixed :)
| |
| 07:54 | <alkisg> vagrantc: I had to force-push due to some launchpad sync issues :/
| |
| 07:54 | In another issue: https://github.com/epoptes/epoptes/commit/61df1fc94cbabc6384257a8ddf5fb5614740a337
| |
| 07:54 | ==> override_dh_installinit: # epoptes does not currently ship any init scripts
| |
| 07:54 | That doesn't mean "services" as well, right? Because we do have a systemd epoptes.service...
| |
| 07:55 | <vagrantc> so i couldn't reproduce the reported issue with ltsp image failing , but at least it caused me to find the epoptes issue
| |
| 07:55 | <alkisg> Haha, nice
| |
| 07:55 | Well, that user just had a bad passwd file,
| |
| 07:55 | mentioning a group 1027 that he had manually deleted from /etc/group,
| |
| 07:55 | <vagrantc> garbage in, garbage out
| |
| 07:56 | <alkisg> so... it's not really an issue with ltsp at all, it's a user issue.
| |
| 07:56 | Not sure how/if I should close it, or even tag it :D
| |
| 07:56 | <vagrantc> alkisg: yes, that's strictly /etc/init.d/ scripts
| |
| 07:56 | <alkisg> Great, thanks for that ^
| |
| 07:56 | <vagrantc> alkisg: the .service files are still installed
| |
| 07:59 | <alkisg> vagrantc: do you think it's time for epoptes 21.02-1? Should I release it? Do you want to? I don't mind whatever you choose
| |
| 08:04 | <vagrantc> alkisg: have a few more days where i can push changes to Debian freely
| |
| 08:05 | alkisg: as long as there aren't major changes ... or i can easily fork and apply selected patches
| |
| 08:05 | <alkisg> vagrantc: if you want me to release a new one right now, I can... there were only shellcheck fixes involved, no major changes to test
| |
| 08:05 | I tested in precise, focal and bullseye, it works
| |
| 08:06 | (precise ==> only the latest epoptes-client changes)
| |
| 08:07 | <vagrantc> i don't have shellcheck readily on hand ... where does it come from? what is it checking?
| |
| 08:08 | it looks even more pedantic that the checks i used to run :)
| |
| 08:08 | <alkisg> It's a debian package that checks shell scripts. It can be integrated into visual studio code, which now is my favorite IDE, and it underlines a lot of silly things like forgotten quotes etc
| |
| 08:09 | I wouldn't have caught the tr -d '[]' thing without shellcheck
| |
| 08:09 | I thought tr wanted character classes inside [] like the other tools, but it doesn't
| |
| 08:10 | Btw visual studio code even comes with a shell check code formatter / beautifier... I'll probably start using that one too
| |
| 08:10 | (all related tools and plugins are open source)
| |
| 08:10 | <vagrantc> i don't imagine i'll start using visual studio :)
| |
| 08:11 | <alkisg> In a few years, we'll have "code ltsp online on github" environment
| |
| 08:11 | The good thing about vscode is that it can run inside a web browser, that's why all companies, redhat included, are investing on it
| |
| 08:11 | So github already has "workspaces" in beta, with vscode
| |
| 08:12 | This will be very handy when I'm at my silent rpi2 and I want a full blown IDE
| |
| 08:12 | <vagrantc> not your space-heater rpi4 ?
| |
| 08:12 | <alkisg> Hehe, nah, rpi4 is ok too. It just needs a thermal cooler
| |
| 08:13 | * alkisg also has collected odroid-c2 and rockpine64 | |
| 08:13 | <vagrantc> rock64-rk3328 ?
| |
| 08:13 | or rockpro64-rk3399 ? :)
| |
| 08:14 | i seem to collect a lot of the pine64 boards...
| |
| 08:14 | <alkisg> rockpro64, but I don't recall the number
| |
| 08:15 | It stutters a bit at youtube videos, probably due to bad hw acceleration drivers in browsers
| |
| 08:15 | <vagrantc> it's a nice one ... haven't used the video output though ... but decent mainline support
| |
| 08:16 | <alkisg> My main use for these are "tv boxes" or "remote desktop to work boxes"... so I usually have the most common/recommended distro for them
| |
| 08:16 | <vagrantc> alkisg: well, if you feel like releasing a new epoptes, then i can probably upload it to debian in a day or two
| |
| 08:17 | <alkisg> vagrantc: sure, thanks, doing so within a few minutes :D
| |
| 08:17 | !tag
| |
| 08:17 | <ltspbot`> tag: tag: git tag -s v20.03 -m 'Version 20.03' && git push --tags
| |
| 08:17 | <vagrantc> if you don't do local tagging a lot, you can default to pushing tags
| |
| 08:17 | [push] followtags = true
| |
| 08:18 | <alkisg> I don't do local tagging at all, so I need the reminder for the `git tag` syntax as well :D
| |
| 08:19 | <vagrantc> :)
| |
| 08:20 | <alkisg> vagrantc: ready (hopefully) :)
| |
| 08:20 | <vagrantc> the newer socat version was uploaded to debian just a few days after i last uploaded epoptes ... good thing i had an excuse to test
| |
| 08:20 | one of the problems of not actually *using* the things i upload :/
| |
| 08:24 | <alkisg> vagrantc: I'm having good progress with my phd; I plan to be finished by summer. So in autumn I'll have enough time to really start supporting debian for school installations
| |
| 08:24 | I'll spend a few months there fixing issues like bad greek fonts etc, and I think I'll apply for a DD,
| |
| 08:24 | and then I'll start migrating most schools to debian :)
| |
| 08:25 | So then I'll know about "debian testing" issues on the day that they happen!
| |
| 08:25 | <vagrantc> hah
| |
| 08:25 | well, by then bullseye should be the new stable release
| |
| 08:26 | but glad to hear you'll be using debian in schools :)
| |
| 08:28 | anyways, i should head off...
| |
| 08:28 | * vagrantc waves | |
| 08:33 | vagrantc has left IRC (vagrantc!~vagrant@unaffiliated/vagrantc, Quit: leaving) | |
| 08:52 | <fiesh> it seems that since /etc/shadow isn't shared to the clients (gentoo), sudo doesn't work... is this a common issue or just something broken under the gentoo installation?
| |
| 08:53 | but I guess it makes sense not to share the server's /etc/shadow
| |
| 08:53 | so I suppose hand-crafting one would be an acceptable solution, only giving sudo rights to those users explicitly?
| |
| 08:53 | <sebd> here sudo works on LTSP clients
| |
| 08:54 | <fiesh> does it copy the server's /etc/shadow?
| |
| 08:54 | <sebd> (debian)
| |
| 08:54 | It copies a stripped-down copy of /etc/shadow
| |
| 08:55 | <fiesh> ah hmm
| |
| 08:55 | <sebd> I just added my admin to the sudo group (/etc/groups)
| |
| 08:57 | <fiesh> ok I don't even have a sudo group but the traditional unix `wheel` instead -- so maybe that's the reason why the users aren't included
| |
| 08:58 | <sebd> In /etc/sudoers : %sudo ALL=(ALL:ALL) ALL
| |
| 09:01 | <fiesh> yeah I have the same for wheel
| |
| 09:01 | <alkisg> fiesh: new or old ltsp?
| |
| 09:01 | <fiesh> uhm
| |
| 09:01 | probably old ;)
| |
| 09:01 | <alkisg> Then sudo doesn't work
| |
| 09:01 | <fiesh> oh, heh ok
| |
| 09:01 | that answers that, thanks
| |
| 09:01 | <alkisg> The old LTSP doesn't use PAM, it only uses SSH on the custom display manager, LDM
| |
| 09:02 | <fiesh> ah yes indeed
| |
| 09:02 | Aison has joined IRC (Aison!~Asion0@2a02:168:200f:110:69c6:120a:877c:5a19) | |
| 09:02 | <sebd> unless you use the old LTSP with thin clients of course
| |
| 09:02 | * sebd does | |
| 09:02 | <alkisg> Eh, then it would be on the server :)
| |
| 09:02 | Not on the client

| 09:08 | <alkisg> !sudo
| |
| 09:08 | <ltspbot`> I do not know about 'sudo', but I do know about these similar topics: 'fat-sudo', 'sudoers'
| |
| 09:08 | <alkisg> !fat-sudo
| |
| 09:08 | <ltspbot`> fat-sudo: to allow members of the sudo group to execute "sudo" in fat clients without a password prompt, put this in lts.conf: RCFILE_01="echo '%sudo ALL=NOPASSWD: ALL' >> /etc/sudoers"
| |
| 09:08 | <alkisg> !sudoers
| |
| 09:08 | <ltspbot`> sudoers: Not recommented for security reasons: RCFILE_01="echo USER ALL=NOPASSWD: /path/to/program >> /etc/sudoers". USER and /path/to/program can also be ALL.
| |
| 09:08 | <alkisg> fiesh: possible workarounds for ltsp5 ^
| |
| 09:09 | <fiesh> hmm yeah, I don't think I want to go for NOPASSWD, thanks
| |
| 09:09 | <alkisg> https://en.wikipedia.org/wiki/Wheel_(computing) => The term was derived from the slang phrase big wheel, referring to a person with great power or influence
| |
| 09:09 | Meh I prefer "sudoers" :)
| |
| 09:09 | <fiesh> but putting entries into the clients' /etc/shadow by hand is an acceptable workaround for me
| |
| 09:09 | <alkisg> !root
| |
| 09:09 | <ltspbot`> I do not know about 'root', but I do know about these similar topics: 'ROOT_PASSWORD_HASH', 'chroot'
| |
| 09:10 | <alkisg> !ROOT_PASSWORD_HASH
| |
| 09:10 | <ltspbot`> ROOT_PASSWORD_HASH: To be able to login as root in vt1, with password "qwer1234", put this in lts.conf: INIT_COMMAND_ROOT_HASH="sed 's!^root:[^:]*:!root:\$6\$p2LdWE6j\$PDd1TUzGvvIkj9SE8wbw1gA/MD66tHHlStqi1.qyv860oK47UnKcafSKqGp7cbgZUPlgyPv6giCVyCSCdJt1b0:!' -i /etc/shadow"
| |
| 09:10 | <alkisg> While this is for the new ltsp, you can see the idea ^
| |
| 09:10 | <fiesh> wheel's the old school unix group for administrators
| |
| 09:10 | <alkisg> This will allow you to put only a "root" shadow entry, a bit safer
| |
| 09:10 | <fiesh> yeah I have a root entry, doing an `su` works on the clients
| |
| 09:10 | so it's all not a big deal
| |
| 09:11 | was just wondering if there was an elegant solution, but it's ok that old ltsp doesn't have that
| |
| 09:11 | <alkisg> I know that fedora etc use "wheel" instead of "sudo", I was just curious about the origin, as I didn't know the phrase "big wheel"
| |
| 09:11 | We do say "the last wheel of the car" here, but we don't have a "big wheel" expression
