| |
| 08:58 | <vasanth> Sorry what commands are all these?/
| |
| 09:01 | what will this nbd image compression do for us....i have actually removed the conf file

| 09:43 | <vasanth> ok thank you
| |
| 09:44 | Any manager for thin client??
| |
| 09:44 | <alkisg> !epoptes
| |
| 09:44 | <ltsp`> epoptes: Epoptes is a computer lab administration and monitoring tool. It works on Ubuntu and Debian based labs with LTSP or non-LTSP servers, thin and fat clients, standalone workstations, NX clients etc. More info: http://www.epoptes.org
| |
| 09:44 | <vasanth> especially on ubuntu??
| |

| 12:47 | <pingufan> Hello, can somebody, please, help me with openSUSE 12.3 x64 and kiwi-ltsp? It was working fine, but since a system update the client only boots up a part and then reboots after displaying incorrect kernel version.
| |
| 12:48 | Sad to say, but in #kiwi-ltsp noone is present, and in #suse also noone answers.

| 14:08 | <schlady> Hello! Does anybody else experience very poor performance when viewing/scrolling pdf files in evince? I am using ubuntu 14.04 lts. When scrolling in the document I see about 600Mbit/s going over network, that’s insane!

| 14:30 | work_alkisg is now known as alkisg | |
| 14:30 | <alkisg> !flash
| |
| 14:30 | <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
| |
| 14:30 | <alkisg> schlady: ^
| |
| 14:31 | Sure pdf is not flash, just to get an idea why remote desktop is so heavy for the network
| |
| 14:31 | Where applicable, do prefer diskless ltsp fat clients instead of thins...
| |
| 14:33 | <schlady> Yes, this was also the solution I proposed - going to fat diskless clients.
| |
| 14:33 | <alkisg> You can also use localapps, but they're more error prone and more difficult to maintain
| |
| 14:35 | <schlady> But the performance with evince was much with 10.04. I always used encrypted traffic without LDM_DIRECTX.
| |
| 14:35 | … much better
| |
| 14:36 | Do you use NBD images with fat clients?
| |
| 14:36 | <alkisg> Maybe they introduced "smooth scrolling" after 10.04
| |
| 14:36 | <schlady> might be, yes.
| |
| 14:36 | <alkisg> Maybe there's even some gsetting to disable it, you could google a bit
| |
| 14:36 | Yes, nbd with fats
| |
| 14:36 | !ltsp-pnp
| |
| 14:36 | <ltsp`> ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
| |
| 14:36 | <alkisg> Specifically, this ^
| |
| 14:37 | <schlady> Ok. So you always have to rebuild the nbd images when you install new software?
| |
| 14:38 | <alkisg> Yes, unless I'm in a testing mode, where I use btrfs+nbd, or nfs
| |
| 14:40 | <schlady> I couldn’t get ltsp to work with nfs the last time I tried.
| |
| 14:41 | btrfs just for snapshots?
| |
| 14:42 | <alkisg> No, for compression too
| |
| 14:42 | It needs 3 times less network bandwidth
| |
| 14:42 | Switching to nfs is very easy at least on debian/ubuntu
| |
| 14:48 | alkisg is now known as work_alkisg | |
| 14:48 | <schlady> I think I have to try that again. Thanks so far!

| 20:14 | <djeis97> How difficult is it to configure a second terminal server? I figure it's not as simple as installing the ltsp packages and adding the second server's ip to the lts.conf...
| |
| 20:15 | But I don't have access to my setup atm, and I was curious.
