| 20:10 | <sbalneav> vagrantc: have a look now
| |
| 20:10 | I now have the sshfs mounts happening
| |
| 20:10 | plus the cleanup
| |
| 20:10 | I've simplified the tree completely.
| |
| 20:10 | Now the python module's doing most of the work.
| |
| 20:12 | On a fat client, I can now:
| |
| 20:12 | log in with lightdm + gtk_greeter
| |
| 20:12 | home dir is mounted with sshfs
| |
| 20:12 | user geom is brought over into extrausers
| |
| 20:13 | auth during screen lock works.
| |
| 20:13 | Can launch X programs on the server and display on the client.
| |
| 20:14 | On logout, sshfs is unmounted, tunnel is terminated, and processes are cleaned up.
| |
| 20:19 | * vagrantc cheers! | |
| 20:24 | <sbalneav> What I really should do is get off my butt and replace ltspfs.
| |
| 20:26 | <vagrantc> i know alkisg had at one point thought about just using sshfs with reverse mounts or something
| |
| 20:27 | <sbalneav> Here was my thought
| |
| 20:27 | Write a fuse filesystem that uses X atoms to communicate.
| |
| 20:28 | That way, if you have an SSH tunnel, the filesystem stuff would be encrypted over the tunnel
| |
| 20:28 | <vagrantc> given that many projects are moving away from X ... might be good to not rely on X specific features
| |
| 20:28 | even crusty old X developers are nudging people to move away from it
| |
| 20:29 | <sbalneav> What replaces X?
| |
| 20:30 | <vagrantc> i think it's still open what will replace it
| |
| 20:31 | that's why i like sticking to the ssh tunnel and whatnot
| |
| 20:32 | although, from what i gather, noting really replaces network-transparent X :/
| |
| 20:32 | nothing
| |
| 20:32 | <sbalneav> Wonder if we could write something that uses stdio and makes use of the existing pre-plumbed tunnel.
| |
| 20:33 | Everybody's down on X. But it *works*.
| |
| 20:33 | <vagrantc> yes, i think using the ssh tunnel for communications might be the best way forward
| |
| 20:34 | <sbalneav> And so far as I've ever seen, none of the so-called "alternatives" do even 1/4 of what X can do.
| |
| 20:34 | <vagrantc> that said, i've been long thinking we should move towards defaulting to a fat client model, in which case these things become moot, except for maintaining compatibility with thin client implementations
| |
| 20:35 | <sbalneav> I'm fine with going fat client.
| |
| 20:35 | <vagrantc> sbalneav: i hear you! at the same time, i don't want to invest new technology into something that's softly deprecated
| |
| 20:35 | <sbalneav> Yeah, fair enough. Fat client makes the problem go away, and quite frankly, I'm perfectly happy saying "Thin client only just doesn't get localdevices anymore"
| |
| 20:36 | <vagrantc> e.g. keep maintaining the stuff we have with X, but probably not develop new stuff
| |
| 20:36 | <sbalneav> Well, with this pam module method, we're really not dependent upon X at all.
| |
| 20:36 | <vagrantc> exactly why it's so exciting! :)
| |
| 20:37 | frees up a lot of options
| |
| 20:37 | whatever way going forward will almost surely support PAM
| |
| 20:37 | <sbalneav> right.
| |
| 20:37 | Well, what's there right now, at least for me, is workable.
| |
| 20:38 | <vagrantc> sbalneav: so, my rough idea for a plan to keep moving forward is to get fat clients working beyond a proof of concept, and then spend some time seeing what we can do for thin clients
| |
| 20:38 | <sbalneav> Yes. Seems logical; get the fat client stuff working, which, unless my setup is somehow really wierd, should be working mostly as-is and where-is now.
| |
| 20:38 | <vagrantc> once we have a solid fat client implementation, it'll inform how difficult it will be to do the remaining thin client bits
| |
| 20:40 | <sbalneav> The nice thing is with this; there's next to no C code left.
| |
| 20:43 | <vagrantc> cool as C code is, i think that's a good thing :)
| |
| 20:43 | <sbalneav> I'm happy to shrink LTSP down to a bare minimum.
| |
| 20:44 | <vagrantc> yeah. make other projects do the work. :)
| |
| 20:53 | gp has joined IRC (gp!~gp@104-14-168-137.lightspeed.rcsntx.sbcglobal.net) | |
| 21:12 | <vagrantc> sbalneav: looking forward to taking your new code for a spin :)
| |
| 21:12 | <sbalneav> Cool
| |
| 21:13 | I think it's gonna need a bit more bulletproofing. But, I think it's workable as-is.
| |
| 21:14 | <vagrantc> though for now, i should get a short walk in and get some sleep and adjust my timezone before my visit with alkisg tomorrow :)
| |
| 21:15 | this hotel wifi is silly ... it blocks http connections with a registration/login page, but all other ports, including https, work fine :)
| |
| 21:16 | <sbalneav> "no one does anything else but web, right?!"
| |
| 21:17 | <vagrantc> what's funny, is with the https-everywhere extension, i didn't even figure it out the pattern for quite a while
| |
| 21:18 | * vagrantc is also glad that this new code is conforming to vagrantc's plot to switch to git | |
| 21:20 | <sbalneav> Oh, quite happy with going to git.
