flash: Yes, flash sucks. An HD full screen 30 fps video needs 2.5 Gbps bandwidth (1920×1080×4×30)! Make sure you have LDM_DIRECTX=True in your lts.conf file, or if it's just youtube you're after, try some flash replacing plugin like http://linterna-magica.nongnu.org

<Guest86370>
Hi, to prevent the Google Chrome warning about 32 bit systems. I have install a 64bit image on the server which is working fine. 2 machines are old and can not boot 64bit is there a way to boot those with the old i386 image? Thanks
08:15
<alkisg>
Guest86370: sure, you can configure the dhcp server to send a different boot filename for those clients
08:16
You can also use chromium-browser, which doesn't show a warning for i386 clients
08:18
<railr>
Hi Alkisg, if I am transferring an entire LTSP server to a new LTSP server, how exactly would this work? Would I only have to copy across the data using rsync or would the trasnferring process be much harder?
08:19
<Guest86370>
yes but then you have all the plugin issues. I would rather have a bias towards 64 bit clients.
08:19
<alkisg>
railr: this is a generic question not related to ltsp, you can use a distro channel for that, e.g. #ubuntu.
08:20
Guest86370: then go to option (1), configure your dhcp server or pxelinux.cfg/01-mac-address
08:21
<Guest86370>
ok that can be done? I have looked for examples and can not see any. I am using standalone server. So is this done on /etc/ltsp/dhcpd.conf?
08:22
<alkisg>
Either on /etc/ltsp/dhcpd.conf or on /etc/dnsmasq.d/ltsp-server-dnsmasq.conf or on /var/lib/tftpboot/ltsp/amd64/pxelinux.cfg/01-mac-address
08:23
I don't know the syntax for dhcpd.conf, I'm using dnsmasq, but you just need to define a section for two specific mac addresses
08:24
<Guest86370>
Great, thanks. I will look at this and report back. I think this maybe an increasing issue. I have always used 32 bit clients but times change.
08:24
<railr>
I'm actually using a boot option on my mikrotik to do network booting.
08:27
<alkisg>
Guest86370: it would be best if i386 support was dropped from google-chrome in e.g. 5 years, because then all i386 clients would only be able to function as thin clients anyway, not as ltsp fat clients, so a generic thin image could be used as a fallback for them
08:27
!precise-i386
08:27
<ltsp>
precise-i386: Ubuntu 12.04 compressed btrfs chroot to boot really old clients (non-pae, >=64MB RAM): http://ts.sch.gr/repo/livecd/images. You can find the image, a screenshot and a README there.
08:31
<Guest86370>
Thanks for that, I am not using btrfs though. I have my server running on Proxmox so I can keeps snapshots that way.

08:40
<alkisg>
Guest86370: that's a generic image that can boot all i386 clients, it doesn't involve using btrfs on your server, but anyway ignore it, it was just meant as a thought for the future

<||cw>
Statler_: so that execs in-session if it's not a thin client?
13:50
<Statler_>
yes
13:50
we have clients, taht connects via X2Go
13:50
that
13:50
<||cw>
you should do a diff -u and post on https://bugs.launchpad.net/ltsp
13:52
<railr>
Statler_: Hi Statler, how exactly are you using x2go to connect up your thin clients?
13:53
<Statler_>
we connect the server which is lts-server with client running x2go too
13:54
with this patch the call for i.e. firefox is the same for all cleints
13:58ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu)
14:09
<railr>
Statler_: I see, because currently the thin clients at my site get pointed towards my ltsp server and it boots up that way.
14:09
<||cw>
railr: they're doing both, regular thin clients and also remote x2go clients
14:11
the patch allows that thin clients exec localapps locally like normal, but x2go or vnc clients would exec the localapps in the remote session
14:11
also could be useful for multiseat
14:32
<Statler_>
right
14:32
one menuentry for all :)
14:42
<alkisg>
Statler_: you can create program overrides in /usr/local/bin. Then menus will use those. And those wrapper entries can have the "run natively or via ltsp-localapps" code that you want.

14:43
<Statler_>
alkisg, yes. but I thought that others have perhaps the same ...
14:43
<alkisg>
Unfortunately ltsp followed the "don't modify the server" approach, while `ltsp-config localapps add/remove/list xxx` would be much easier to code
14:44
Maybe we'll do that in ltsp 6, we'll see
14:44
Statler_: in any case, as ||cw said, merge requests should be filed in a bug report in launchpad...
14:44

<ltsp>
ltsp-bug: To file a bug report for upstream LTSP, go to https://bugs.launchpad.net/ltsp

<Statler_>
for me it works. only an idea for all ...

||cw, has instructed me ;)

So, I can login with XDM and a combination of pam_external and nss_external.

So there's something that nss_external is doing that lightdm *specifically* doesn't like.

<sbalneav>
Worked on it all day today. Didn't make progress. Not sure what I'm doing wrong; I'll get into it on the weekend. Problem appears to be in the nss side of things, so worst case, nss_extrafiles is a workable fallback.
21:08
I'll do some more hacking this weekend when I'm up at the cottage
21:11
<vagrantc>
sbalneav: ok, so still hold off a bit for further packaging?
21:11
<sbalneav>
Yeah.
21:12
<vagrantc>
sbalneav: main advantage of the nss-external over extrafiles is just one of flexibility?
21:12
<sbalneav>
Yes.
