| |
| 04:02 | <ltsp> The operation succeeded.

| |
| 07:29 | <ltsp> 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

| 08:04 | <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

| 13:49 | <||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
| |
| 13:58 | ben_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.
| |
| 14:42 | GodFather has left IRC (GodFather!~rcc@96-35-101-212.dhcp.bycy.mi.charter.com, Ping timeout: 276 seconds) | |
| 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-bug
| |
| 14:44 | <ltsp> ltsp-bug: To file a bug report for upstream LTSP, go to https://bugs.launchpad.net/ltsp
| |
| 14:44 | <Statler_> for me it works. only an idea for all ...
| |
| 14:45 | https://bugs.launchpad.net/ltsp/+bug/1588847
| |
| 14:45 | ||cw, has instructed me ;)
| |
| 14:45 | <alkisg> Nice :)
| |
| 14:45 | <Statler_> alle done!

| 21:07 | <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?
| |
