03:26work_alkisg is now known as alkisg
03:40
<alkisg>
New debian policy: "The default web document root is now `/var/www/html'"
03:41
...tftp goes in /var/tftp?
03:43
<vagrantc>
i didn't think there was a policy regarding tftp
03:43
<alkisg>
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=485559
03:43
==> Also, Russ Allbery[2] argued that using /srv/* might violate the FHS. So I've switched to /var/lib/tftpboot.
03:43* alkisg shrugs...
03:49* vagrantc shrugs harder
03:56
<alkisg>
OK, at the end they seem to agree with /srv/tftp, but packages should not ship files there,
03:56
...so we could switch our defaults there in ltsp6...
04:01
vagrantc: have you seen this one? https://packages.debian.org/search?keywords=xserver-xorg-video-modesetting
04:01
...is that an alternative to XSERVER=vesa? What would we need to put in lts.conf to use that?
04:03
<vagrantc>
alkisg: my guess is it would only work with the KMS framebuffer
04:04
<alkisg>
vagrantc: that's better than vesa though, right?
04:04
i.e. it would allow all resolutions, vt switching...
04:04
<vagrantc>
for drivers that support it, i presume so
04:05
it's probably highly dependent on the driver
04:05
<alkisg>
Wait, isn't that a generic driver to be used with vesa-compliant cards?
04:05* vagrantc has no idea
04:05
<alkisg>
I thought its goal was to "replace" vesa xorg driver in the kms world
04:08
http://manpages.ubuntu.com/modesetting
04:35
stgraber: # grep echo debian/40-ltsp
04:35
DESKTOP_SESSION=$(echo $1 | sed "s/gnome-session --session=//g")
04:35
That echo $1 there should be echo "$1"
04:35
It breaks Lubuntu logins, https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/1330252
04:35
You're the only one with access to commit that, right?
04:35
(Ubuntu-specific...)
04:37
maxtrax: see above ^
04:38
<vagrantc>
oh no, ive gone another huge release cycle without adding support for ltsp-config nfs
04:39
<alkisg>
:)
04:41
<vagrantc>
alkisg: you saw wouter fixed an issue with NBD copy-on-write support?
04:41
alkisg: so that you can set up the cow file in a separate location or something...
04:41
<alkisg>
vagrantc: the one that allows specifying the temp file location/
04:41
<vagrantc>
yeah
04:41
<alkisg>
Right, we could do that before but only with symlinks
04:41
<vagrantc>
right, which was ugly.
04:41
<alkisg>
The problem with cow is that squashfs isn't writeable anyway
04:42
<vagrantc>
but there are so many other filesystems
04:42
<alkisg>
But now that btrfs is mainstream and stable enough, we could probably switch to btrfs-with-compression images
04:43
The other problem there, is what to do with the "remaining free space"
04:43
E.g. suppose a chroot is 1 GB uncompressed, 300 MB compressed with btrfs,
04:43
how large would the btrfs loopback image be? 1 GB?
04:43
Sparse?
04:44
With squashfs+tmpfs+aufs/overlayfs, we don't need to care about those questions...
04:45
Also, in the future, ssd disks are going to beat the lan speed by a long margin
04:46
We'll probably want to use them then, for local caching of the nbd image
04:46
So if we're going there, there's not much point in server-side cow anymore...

!lubuntu

retrieving files and updates from archive.ubuntu.com is slow

I thought that there are problems with debootstrap but it looks like apt-get retrieve hangs also

hi alkisg, I know you’re busy, but have you had any more thoughts about the USB drive mounting issue?

woops, wrong window.
10:06
alkisg: I think I’ve solved it, it’s a polkit issue.
10:06
<alkisg>
Yes, we've committed a fix about that
10:06
So it shouldn't be a polkit issue anymore ;)
10:06
See the ltsp-trunk about polkit commits
10:06
<rickogden>
when was that committed?
10:06
ah ok
10:07
has that been pushed to the repositories?
10:09
<alkisg>
Before 14.04
10:09
What's your version again?

With the greek school ppa or not?

alkisg: yes :)
10:13
<alkisg>
It should be ok then, the session is considered active
10:14
<rickogden>
well, I’ve just added a pkla for a few udisks policies, set them all to “yes”, and that seems to have worked

12:22
following this: https://help.ubuntu.com/community/UbuntuLTSP/LTSP-Cluster tutorial

<gothaggis>
what needs to be done to allow ssh to thin client from server? i generated keys, copied public key to thin client root (.ssh/authorized_keys) - updated thin client image....and when i try to ssh from server to a thin client (while specifying the key to use) i get 'read from socket failed: connection reset by peer". this is Ubunt 14.04 btw
19:14
last couple lines of ssh verbose:
19:14
debug1: Enabling compatibility mode for protocol 2.0
19:14
debug1: Local version string SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2
19:14
debug1: Remote protocol version 2.0, remote software version OpenSSH_6.6.1p1 Ubuntu-2ubuntu2
19:14
debug1: match: OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 pat OpenSSH_6.6.1* compat 0x04000000
19:14
debug1: SSH2_MSG_KEXINIT sent
19:14
Read from socket failed: Connection reset by peer
19:15
I enabled root account on thin clients
19:15
and PermitRootLogin is set to yes in sshd_config
19:18
<Hyperbyte>
gothaggis, is sshd started on your clients?
19:23
<elias_a>
Hyperbyte: Not before the voting has ended? :P
19:42
<gothaggis>
Hyberbyte, sshd is indeed running on the client
19:44
and if i telnet to the thinclient on port 22 i get the SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2 prompt
