sbalneav: so, did some brief testing beffore sleeping
06:39
sbalneav: worked fine for fat client for the most part, although screen locking needed additional updates for /etc/pam.d/*screensaver*
06:39
sbalneav: i tried using *-common unsuccessfully
06:39
sbalneav: thin clients hang on logout, though
06:39
sbalneav: the ltsp-cleanup.sh disappeared, not sure if we need something to replace that
06:40
e.g. ltsp-cleanup.sh was removed from git

SCREEN_07_WAIT_FGCONSOLE=False
07:30
SCREEN_08="ldm -seat seat0"
07:30
SCREEN_08_LDM_USERNAME="administrator"
07:30
So, we support directives with SCREEN_xx in front of them
07:30
They override the generic ones
07:30
E.g. SCREEN_08_LDM_USERNAME overrides LDM_USERNAME
07:31
so... WAIT_FGCONSOLE=False to start all the screens, or SCREEN_07_WAIT_FGCONSOLE=False to only start the 7th screen
07:32
Any better names for that directive? :)

08:07
vagrantc: next I'd like to push this one: https://bugs.launchpad.net/ltsp/+bug/1610304
08:21
vagrantc: i.e. this one: https://launchpadlibrarian.net/277285066/X01-localapps.patch
08:21
So whatever you want changed there... tell it now before the push :P

09:04
2) Remove the "root/.*" line from the same file, otherwise your authorized_keys will get excluded
09:05
1) Remove the "etc/ssh/ssh_host_*_key" line from /etc/ltsp/ltsp-update-image.excludes
09:10
<vagrantc>
so i think we should remove the ssh_host_*_key line from the .excludes
09:11
and if they want to log in as root, they can edit /etc/ssh/sshd_config to use AuthorizedKeysFile
09:11
either through an init-ltsp.d hook or in the server's config
09:12
if they want to same keys to be useable on the server
09:12
<alkisg>
I think they were trying to make it simpler, but works for me... :D
09:12
<vagrantc>
or implemented in this future overlay thing

Should be easy to fix and include it to the next ldm, so that it doesn't have a single commit :D

<sbalneav>
Morning
13:41
alkisg, vagrantc I'm on station
13:44
<vagrantc>
sbalneav: did you catch my comments from backscroll?
13:45
<sbalneav>
Yeah, looks like it's mostly working? Not sure why adding them to -common didn't work, that's what I was doing in my vm
13:45
<vagrantc>
sbalneav: did a bit of testing with your libpam-python hooks, and then started wrapping up some ldm/ltsp5.x issues for debian
13:45
sbalneav: most likely i just did it wrong :)
13:45
<sbalneav>
But you were able to login?
13:45
And you got an SSH tunnel?
13:45
<vagrantc>
was able to log in via lightdm, with ssh tunnel and sshfs
13:46
<sbalneav>
Sweeeeet
13:46
the ltsp-cleanup.sh should be rolled into the ssh.py script.
13:46
If something gets left behind, we'll clean it up in there.
13:46
on the close-session
13:46
<vagrantc>
i did manually tweak the pam.d stuff to get xscreensaver to work ... and while lightdm was logged in, i could also manually configure pam.d to allow login on console
13:47
but i couldn't login via console without lightdm
13:47
my guess is that's just a matter of getting the pam settings correct
13:47
<sbalneav>
We should just figure out what's up with -common, and add it there, then everything would work.
13:47
<vagrantc>
unless there's an issue with it attempting to mount the homedir multiple times or something?
13:48
<sbalneav>
hmmm, that may be.
13:48
I don't detect if it's already mounted.
13:48
I can do that.
13:48
<vagrantc>
i didn't dig in too much deeper as i want to get an ltsp/ldm upload into debian soon to have plenty of grace period for the freeze
13:48
hopefully get that over with tonight and then we can focus on the ltsp6 stuff :)
13:48
<sbalneav>
ok
13:49
I'll look at adding the detect as well.
13:49
<vagrantc>
cool
13:49
<sbalneav>
for already mounted homedir.
13:49
I'm off sick today, spent all weekend with a lung infection. So I have some time today :D
13:50
<vagrantc>
sbalneav: gak! no sooo happy to hear that
13:50
though thankful you find ltsp hacking as a restful activity :)
13:51
<sbalneav>
Doing something useful always makes me happy :D
13:52
<vagrantc>
alkisg pushed multi-seat support for LTSP/LDM today :)
13:59
highvoltage: oh, did you get a chance to take a stab at LDM artwork?
14:00
highvoltage: probably best to get that updated before freeze :)
14:05
<highvoltage>
vagrantc: it's high on my priority list. I was meaning to get to it over the weekend but that didn't work out.

alkisg: got it:
14:44
-exec xinit /usr/share/ltsp/xinitrc /usr/sbin/ldm -- ${DISPLAY} vt${TTY} -auth ${XAUTHORITY} ${X_ARGS} "$@" -br >/dev/null 2>&1
14:44
+exec xinit /usr/share/ltsp/xinitrc /usr/sbin/ldm -- ${DISPLAY} vt${TTY} -auth ${XAUTHORITY} ${X_ARGS} $@ -br >/dev/null 2>&1
14:45
alkisg: quoting the "$@" passed a null argument to Xorg that it didn't like
14:45
alkisg: i don't *think* that will negatively impact multi-seat

sbalneav: oh, i had also asked about some of the leftover dependencies for the ltsp-pam package ...
14:55
sbalneav: can python-daemon be dropped?
14:56
sbalneav: and maybe net-tools
15:13gvy has joined IRC (gvy!~mike@altlinux/developer/mike)
15:15
<sbalneav>
Yup
15:16
vagrantc: any changes to ltsp-pam to push?
15:23
<vagrantc>
sbalneav: oh yeah, i forgot to push my changes ... just some packaging
15:23
sbalneav: oh, there's no licensing on any of this yet :)
15:24
sbalneav: i'm thinking GPLv3 would be good. libpam-python is GNU AGPLv3
15:25
<sbalneav>
Yeah, I'm fine with that.
15:25
<vagrantc>
though technically, since it's just a module called by libpam-python, i don't think that restricts the licensing really
15:25
<sbalneav>
I'll do whatever's easiest.
15:26
I'm just working on the detect now. I'll just read /proc/mounts.
15:29
<vagrantc>
sbalneav: there is the possibility of using something other than sshfs ... and the mount could be all of /home rather than per-user ... so not sure exactly what should be detected
15:29
such as NFS_HOME and such.
15:30
i think some folks use NFSv4 with kerberos

1) Use the setgid permissions, and handle it with group permissions
