| 01:25 | <MarkH> Hello - we're trying to save files to our LTSP guest instances (specifically RDP links) so they will persist between reboots. We had this working in a lab environment, however we're now running on our production hardware, and files saved to client desktops are not surviving reboots. Can anyone please point me at the doco that covers enabling this ?

| 14:37 | <BuddyButterfly> alkisg: Cups printing works now fine! Tnx! saned also.
| |
| 14:48 | <alkisg> BuddyButterfly: np
| |
| 14:48 | BuddyButterfly: there's no option for saned, but yeah you can do it from net.conf
| |
| 14:48 | Hey sbalneav :)
| |
| 14:49 | <sbalneav> Morning alkisg
| |
| 14:50 | <BuddyButterfly> alkisg: yep, tested it. works fine from net.conf.
| |
| 14:50 | alkisg: also saw that printer config should be done from user dir as to not have to generate a new image when changing printers. Anyway, they do not change very often ;-)
| |
| 14:51 | and when using printer server it is 1 time config globally.
| |
| 14:51 | <alkisg> BuddyButterfly: I'm not sure what you mean there
| |
| 14:51 | Typically, you configure the printer on the server only, not on the image
| |
| 14:51 | And it's only 1 time config globally
| |
| 14:52 | In your case you have a separate printer server? Then you only configure them there 1 time
| |
| 14:52 | And point the client cups to that server
| |
| 14:52 | <BuddyButterfly> alkisg: exactly! That is what I also prefer.
| |
| 14:53 | https://help.ubuntu.com/community/UbuntuLTSP/localprinter
| |
| 14:53 | <alkisg> BuddyButterfly: you don't need to re-generate the image for that
| |
| 14:53 | At all
| |
| 14:53 | No, that's the wrong way to do it
| |
| 14:53 | You don't want local printers, but global printers
| |
| 14:53 | <BuddyButterfly> alkisg: ah, was not aware of this. But now, where you mention it, true, it comes via tftp....
| |
| 14:54 | <alkisg> It's also much easier if the ltsp server is also the printer server
| |
| 14:54 | <BuddyButterfly> so I can leave this step away also ;-)
| |
| 14:54 | <alkisg> But you can put printers to the clients and redirect them to the server via jetpipe
| |
| 14:54 | (included with ltsp)
| |
| 14:55 | <BuddyButterfly> jetpipe, interesting. will also look into it.
| |
| 14:55 | will be afk for some minutes. cu.
| |
| 14:55 | tnx a lot!

| 16:15 | <vagrantc> sbalneav: hrm. latest ltsp-pam git doesn't seem to work for me... maybe i needed to change something in the packaging?
| |
| 16:17 | yup, getting python tracebacks in auth.log
| |
| 16:18 | sbalneav: loosely copied: ioerror, no such file or directory, /var/lib/extrausers/passwd
| |
| 16:20 | * vagrantc dives in and debugs | |
| 16:26 | <vagrantc> touching the /var/lib/extrausers/passwd,group,shadow files seems to partially work around the issue
| |
| 16:27 | but it's not creating a socket
| |
| 16:27 | does look like multi-user support has somewhat been added, though
| |
| 16:34 | sbalneav: do you remember what permissions the /var/lib/extrausers/* should have?
| |
| 16:36 | yup, permissions issues
| |
| 16:37 | so at least passwd and group need to be world-readable
| |
| 16:37 | in general, shadow shouldn't be
| |
| 16:37 | though i suspect this implementation doesn't write anything dangerous in /etc/shadow ... but better to be cautious than reckless
| |
| 16:38 | <sbalneav> Yeah, should be world readable.
| |
| 16:39 | I suppose we should have a chmod in there to ensure the perms.
| |
| 16:39 | Shadow shouldn't be, tho' 600 perms
| |
| 16:43 | <vagrantc> so, it seems like the old code created the file as needed, and for some reason this code doesn't
| |
| 16:45 | <sbalneav> hm
| |
| 16:45 | <vagrantc> working around that bug, it seems to be working nice
| |
| 16:45 | multiple concurrent users work, on console and lightdm ...
| |
| 16:45 | although if you have a user on console and lightdm, whichever logs out first unmounts the homedir
| |
| 16:45 | <sbalneav> Hmm
| |
| 16:45 | <vagrantc> fairly minor issue, though
| |
| 16:46 | <sbalneav> I suspect it's failing when it tries to open the file for read.
| |
| 16:46 | <vagrantc> unlocking screen locker works
| |
| 16:46 | probably just test if it exists and create it if not
| |
| 16:46 | even i could probably come up with a patch for that
| |
| 16:47 | <sbalneav> one sec
| |
| 16:48 | vagrantc: Try that push
| |
| 16:50 | * vagrantc monkey-patched in an "if os.path.exists(fname):" that seemed to work, although shadow is a bit too permissive with permissions | |
| 16:51 | <vagrantc> try/except should work too :)
| |
| 16:51 | <sbalneav> Either-or
| |
| 16:52 | yeah, I'll add in some code to chmod things appropriately.
| |
| 16:52 | I just want to see if that fixes the failure.
| |
| 16:54 | <vagrantc> works for me, just needs some chmod
| |
| 16:54 | <sbalneav> ok
| |
| 16:55 | 644 for passwd and group, 600 for shadow
| |
| 17:00 | <vagrantc> sounds about right
| |
| 17:04 | hah! i can even su from one pam-sshauth authenticated user to another as long as they've logged in at least once
| |
| 17:04 | <sbalneav> vagrantc: try that push
| |
| 17:05 | <vagrantc> don't see it yet
| |
| 17:05 | <sbalneav> derp
| |
| 17:05 | <vagrantc> might be some propegation delay on launchpad
| |
| 17:05 | <sbalneav> git commit and git push are different, REMEMBER that sbalneav
| |
| 17:05 | <vagrantc> oh
| |
| 17:05 | <sbalneav> try now
| |
| 17:07 | <vagrantc> sbalneav: works for me
| |
| 17:08 | <sbalneav> Sets the right perms on shadow?
| |
| 17:08 | <vagrantc> yup
| |
| 17:08 | although it does technically do that after the data ha been written...
| |
| 17:09 | there's a window in which the file is probably world-readable
| |
| 17:09 | small though it may be
| |
| 17:09 | i wonder if it would be better to create the file, chown the file, write data...
| |
| 17:12 | <sbalneav> Well, in our case, since we're not writing anything to it other than "userid:*::::::::"...
| |
| 17:12 | I'd say the added complication isn't worth it.
| |
| 17:12 | If we actually, for some unknown reason, DO end up *actually* storing a password, then I'd say yes.
| |
| 17:12 | <vagrantc> we're not doing that today, but we might want to protect our future forgetful selves :)
| |
| 17:13 | <sbalneav> You can't actually authenticate from extrausers anyway, so...
| |
| 17:13 | There's no pam-extrausers
| |
| 17:13 | <vagrantc> but the file needs to exist, somehow?
| |
| 17:13 | <sbalneav> pam_unix specifically only gets it's info from /etc/{passwd,group,shadow}
| |
| 17:14 | Yeah, lightdm checks to see if it can do a getent shadow user, for some unknown reason.
| |
| 17:14 | And then won't log the user in since they're not a "real" user.
| |
| 17:15 | I'd prefer not to create a shadow entry at *all*.
| |
| 17:15 | <vagrantc> right
| |
| 17:16 | <sbalneav> Let me try again, just to be certain.
| |
| 17:16 | measure twice, cut once.
| |
| 17:21 | yeah
| |
| 17:21 | If you comment out the line where it adds the shadow, lightdm just won't log in
| |
| 17:22 | :(
| |
| 17:22 | You get an "authentication succeeded" message in the auth log, and lightdm just... sits there like a goof.
| |
| 17:24 | Soon as you put the line back in, everything works.
| |
| 17:31 | hmmm
| |
| 17:31 | I wonder....
| |
| 17:31 | epicurus was smart

| 17:49 | <sbalneav> Yeah, I can't find it in the code, but somewhere, if that shadow line isn't there, it just won't work.
| |
| 17:50 | wait
| |
| 17:52 | got it.
| |
| 17:54 | <vagrantc> though fixing lightdm (and possibly other DMs) everywhere would be the ideal long-term, probably need to keep the workaround for now

| |
| 20:29 | <sbalneav> I have to say, I'm kinda excited.
| |
| 20:29 | * vagrantc too | |
| 20:29 | <sbalneav> This is actually working kinda good.
| |
| 20:30 | <vagrantc> suspiciously
| |
| 20:30 | <sbalneav> Waiting for that other shoe.
| |
| 20:30 | <vagrantc> like someone is taunting us
| |
| 20:30 | <sbalneav> Console logins work fine too, now.
| |
| 20:30 | You even get your home dir.
| |
| 20:31 | <vagrantc> should i just release this as libpam-sshauth 1.0 ? :)
| |
| 20:31 | <sbalneav> Logging in multiple times doesn't work; I could make that work by just coming up with a random socket name.
| |
| 20:31 | What do you think?
| |
| 20:31 | <vagrantc> the socket name can be passed around some way?
| |
| 20:32 | <sbalneav> It *should* be in the PAM_SSHAUTH_SOCKET environment variable.
| |
| 20:32 | let me play with it for another day.
| |
| 20:32 | <vagrantc> so it's already done ... nice
| |
| 20:33 | a predictible socket name has some potential exploits anyways, so if it's not too hard, a variable name would be helpful
| |
| 20:33 | <sbalneav> Let me play.
| |
| 20:33 | It may be simple.
| |
| 20:33 | <vagrantc> first i'll test what you've done so far :)

| 21:10 | <vagrantc> sbalneav: works for me, tested: 471430845aab31eeb2eea2f5e08447b149b73fcb Slight amount of code simplification
| |
| 21:11 | <sbalneav> cool
| |
| 21:23 | vagrantc: Multiple same-user login code added; socket is now a tempdir.
| |
| 21:25 | This isn't perfect, and we'll need to figure something out in the session script.
| |
| 21:25 | Here's the problem:
| |
| 21:26 | If you log in once, and your sshfs homedir is mounted, you now have a .ssh dir
| |
| 21:26 | Then the second tunnel, ssh balks, because now the server has a real name, per your .ssh directory, instead of the "server" default one set up by the ltsp ssh host keys.
| |
| 21:27 | so we have to now start the ssh tunnel -O StrictHostKeyChecking=no
| |
| 21:27 | as well
| |
| 21:27 | we need to do something about handling the naive "just mount the sshfs homedir"
| |
| 21:27 | if you log in a second time, you shouldn't re-mount
| |
| 21:28 | but you ALSO can't just execute the fusermount on logout too, since then you'll yank the homedir out from under the other session.
| |
| 21:29 | Logging in multiple times on the same box like this will be... difficult to plumb. And, I'd expect, a very small edge case.
| |
| 21:29 | Not sure if we even want to try solving it.
| |
| 21:34 | <vagrantc> disabling stricthostkeychecking doesn't seem like a good idea
| |
| 21:34 | <sbalneav> No
| |
| 21:34 | It doesn't, does it?
| |
| 21:34 | <vagrantc> yeah, i'd rather not add more insecurities in order to support an edge case
| |
| 21:34 | <sbalneav> ok
| |
| 21:34 | So I'll yank that bit.
| |
| 21:35 | But now, at least, your socket dir is a random string.
| |
| 21:35 | <alkisg> sbalneav, vagrantc, so switching to vt1 and logging in to troubleshot something wrong in xorg, won't be supported?
| |
| 21:35 | I don't think that's an edge case...
| |
| 21:36 | <vagrantc> oh, stricthostkeychecking isn't as bad as i thought
| |
| 21:36 | * vagrantc also tends to set checkhostip=no | |
| 21:37 | Freejack has joined IRC (Freejack!~Freejack@unaffiliated/freejack) | |
| 21:37 | <sbalneav> Well, leave it as is, for the moment, which means the ssh tunnel gets plumbed correctly.
| |
| 21:38 | Then we just need to figure out a good way to not mount and unmount an already mounted homedir
| |
| 21:38 | <alkisg> To not mount ==> easy part, if it's already mounted
| |
| 21:38 | <sbalneav> right
| |
| 21:38 | but how do we know not to UNmount
| |
| 21:38 | <alkisg> To not unmount ==> will need some `loginctl` or `w` magic...
| |
| 21:38 | <sbalneav> lsof, maybe?
| |
| 21:40 | <alkisg> One way would be with pids
| |
| 21:41 | But personally i'm fine with relying on systemd for that... :)
| |
| 21:42 | `loginctl list-sessions` seems fine...
| |
| 21:43 | ...better yet, loginctl user-status alkisg
| |
| 21:43 | It has a "sessions" variable there
| |
| 21:47 | <sbalneav> ah, so if sessions > 1, don't fusermount?
| |
| 21:48 | seems.... logical :D
| |
| 21:48 | <vagrantc> might be a tiny chance of race conditions if both were logging out at the same time...
| |
| 21:49 | <alkisg> loginctl show-user alkisg | awk '/^Sessions=/ { print NF }'
| |
| 21:49 | This should return the number of sessions
| |
| 21:49 | <sbalneav> Would you quit poking holes in this, geez :D
| |
| 21:50 | <vagrantc> but the worst that happens is the homedir stays mounted, no?
| |
| 21:50 | <sbalneav> it may not even be a problem, hold on.
| |
| 21:51 | <alkisg> ...we could also just keep a counter...
| |
| 21:51 | <vagrantc> i'm more worried about the counter getting out of sync than about loginctl showing the wrong output
| |
| 21:51 | or, the right output at the wrong time :)
| |
| 21:51 | really, it's a minor risk, i think
| |
| 21:51 | <sbalneav> hahahaha
| |
| 21:51 | it's not a problem
| |
| 21:52 | log in on console
| |
| 21:52 | get homedir
| |
| 21:52 | log in on X
| |
| 21:52 | get homedir
| |
| 21:52 | log out on X
| |
| 21:52 | homedir still exists in console
| |
| 21:52 | log out of console
| |
| 21:52 | all homedirs gone
| |
| 21:52 | <alkisg> is this because of double mounts?
| |
| 21:52 | <sbalneav> Not sure why it works
| |
| 21:53 | <vagrantc> i've definitely seen it fail
| |
| 21:53 | <sbalneav> Intuition tells me it shouldn't
| |
| 21:53 | <alkisg> I think it'll be error-prone if it's double mounts
| |
| 21:53 | <vagrantc> e.g. unmount the homedir
| |
| 21:53 | <alkisg> I.e. if it fusermounts over the existing fusermount
| |
| 21:53 | <sbalneav> Try it and see, with what's in there.
| |
| 21:53 | I'm thinking that's what's happening.
| |
| 21:53 | ohh, wonder if I mix them ip
| |
| 21:53 | up
| |
| 21:53 | <alkisg> Try removing the allow_non_empty or whatever it's called
| |
| 21:55 | <sbalneav> I gotta go soon, but yeah, we should have some logic in there
| |
| 21:55 | I like the loginctl idea
| |
| 21:55 | we could use that for both login and logout.
| |
| 21:57 | <vagrantc> i've definitely got double-mounts
| |
| 21:58 | and it unmounted the homedir ...
| |
| 21:59 | but because we're doing a lazy unmount, it left it open or soemthing?
| |
| 22:04 | <sbalneav> Yeah, maybe
| |
| 22:04 | It's sub-optimal, as it is now, and "works" by accident, and not design :D
| |
| 22:04 | <vagrantc> sbalneav: that said, your multi-login code for a single user seems to work :)
| |
| 22:05 | * vagrantc relocates for lunch | |
| 22:05 | <sbalneav> I'd relocate to italy. They have some nice lunches there.
| |
| 22:06 | <vagrantc> no experience with italy, but you should totally try greece!
