| 12:08 | <gp> does anyone have any recommendations for an IDE that works well with LTSP? I am using Ubuntu14.04/Mate-Desktop. I've been trying Liclipse which is a version of eclipse that comes configured for python/html/javascript coding... but the performance with eclipse is terrible. Hoping I can find something with a similar feature set that performs better in this enviornment
| |
| 12:10 | <muppis> gp, I think performance issue more related do you run it as local or remote app. Tried run it as local?
| |
| 12:11 | <gp> I am even having problems on fat clients. Maybe it is an issue with networked filesystem?
| |
| 12:12 | <muppis> That's one possibility.
| |
| 12:13 | If you can, drop fat client to local hdd and try there. Then you can rule out is it network related.
| |
| 12:14 | <gp> Do you mean that there is an option to have the fat client copy the image to a local hard drive?
| |
| 12:14 | Or do you mean use a local os to test the program?
| |
| 12:15 | <muppis> I mean fat client loaded from local hdd. That has to bee done manually, because there's few trick to do to make fully boot from local.
| |
| 12:16 | I think more easier to make local os use nfs mounted homes. :D
| |
| 12:17 | Enabled direct X?
| |
| 12:17 | Less secure, but lot faster.
| |
| 12:17 | And reduces network traffic which can help as well.
| |
| 12:17 | <gp> I could try direct X if that will tell me something. But I do not think that can be the solution because of what it gives up
| |
| 12:18 | <muppis> You can get a clue about solutions at least.
| |
| 12:18 | <gp> good point. i will try that first
| |
| 12:19 | If that helps, does that mean to keep the option enabled I would need to have more cpu/memory on the fat client?
| |
| 12:21 | <muppis> Not really. Direct X should be easier to client, because doesn't need to do encryption/decyrption anymore.
| |
| 12:23 | <gp> Right. I mean if I want to keep it enabled. If disabling it helps, then to keep it enabled I would need more cpu/ram on the client?
| |
| 12:28 | <muppis> Lost in sentense. :D If you enable direct X, it doesn't use encryption and transfer display data as is, so it screen update is faster and uses less cpu and network.
| |
| 12:32 | <work_alkisg> gp, what's your client CPU/RAM?
| |
| 12:32 | work_alkisg is now known as alkisg | |
| 12:32 | <alkisg> Also, do you have a full gigabit network?
| |
| 12:32 | <gp> yes full gigabit.
| |
| 12:33 | <alkisg> CPU/RAM?
| |
| 12:34 | <gp> I haven't tested this on lots yet. But the one is an http://ark.intel.com/products/33924/Intel-Core2-Quad-Processor-Q9550-12M-Cache-2_83-GHz-1333-MHz-FSB with 4gb ram
| |
| 12:35 | <alkisg> And is that a fat client or thin?
| |
| 12:35 | <gp> Fat
| |
| 12:35 | I've watched with process manager and the client hasn't run out of ram
| |
| 12:35 | <alkisg> Then it should run as good as if you had liclipse installed in a local hard disk
| |
| 12:36 | Maybe there's no problem at all with ltsp and it's just that that program is slow?
| |
| 12:36 | <gp> Thats what I thought. So I think I need to find another IDE
| |
| 12:36 | <alkisg> It's not an ltsp question then, though...
| |
| 12:36 | People here would tell you about fixing ltsp, while you need another app
| |
| 12:36 | So better ask in #ubuntu etc
| |
| 12:36 | And no need to mention ltsp at all when you're asking there..
| |
| 12:37 | <gp> Well I was asking for recommendations for an IDE that people have used successfully with LTSP
| |
| 12:37 | <alkisg> I understand that you think that it's related, but it's not "related enough" to get good answers here
| |
| 12:38 | I could also ask here about "good keyboards that people have used with ltsp", but it's also not related
| |
| 12:38 | <gp> I understand.
| |
| 12:38 | <alkisg> I.e. I think you'll get better answers if you ask to appropriate channels
| |
| 12:40 | <gp> But I would tell you I like the logitech wireless keyboards with the little solar panel so you don't have to walk around and change batteries. =)
| |
| 12:40 | <muppis> 4~ nbnnhttp://kuvaton.com/kuvei/when_mom_tries_to_wake_me_up_early_in_the_weekend.gifµ
| |
| 12:40 | <alkisg> Ouch that had to hurt :)
| |
| 12:41 | <gp> oh ouch
| |
| 12:41 | <alkisg> gp, I'm sure that even if I asked about "running shoes" here I'd also get some good answers, but there's a reason that different channels exist and we're not all in a single "#chat-about-anything" channel :)
| |
| 12:42 | <gp> sorry I was just being funny
| |
| 12:42 | <alkisg> :)

| 19:30 | <johndoc> is this an active channel?
| |
| 19:30 | <quinox> kind of
| |
| 19:30 | <johndoc> great, i could really use some guidance
| |
| 19:31 | I built an ltsp server in KVM and when I load up my thin client i get "Error: Socket Failed: Connection timed out" and drops me into busybox
| |
| 19:32 | I was following this guide if that helps any: http://www.havetheknowhow.com/Configure-the-server/Install-LTSP.html
| |
| 19:32 | <quinox> let me check my problem solving manual
| |
| 19:33 | <johndoc> it worked (mostly) on a regular server, but not much luck in KVM
| |
| 19:33 | championofcyrodi has joined IRC (championofcyrodi!~cott@50-205-35-98-static.hfc.comcastbusiness.net) | |
| 19:33 | <quinox> In case you get BusyBox when booting something went wrong. Ways to debug:
| |
| 19:33 | On duivenkracht: tail -f /var/log/syslog | grep nbd while booting will tell you information about the client mounting the fs
| |
| 19:33 | On thin client: nbd-client 10.50.0.8 2000 /dev/nbd0 will mount the image manually
| |
| 19:33 | duivenkracht = the main LTSP (TFTP/NBD/NFS) server
| |
| 19:34 | 10.50.0.8 2000 -> duivenkracht's IP and NBD's port number
| |
| 19:34 | although I recently switched from NBD ports to NBD names, so that last command should be updated
| |
| 19:35 | I'd start with the last command
| |
| 19:36 | manually mounting the FS from busybox
| |
| 19:47 | with a mount name it should be in my case: nbd-client --name /opt/ltsp/amd64 10.50.0.8 /dev/nbd0
| |
| 19:48 | I'm not entirely sure about this, but AFAIK the /opt/ltsp/ is used by default and the amd64 is derived from ... your tftp folder name maybe?
| |
| 19:49 | I do know it can be overwritten by adding nbdroot= to the kernel parameters inside the pxelinux.cfg/default file on the TFTP
| |
| 19:54 | by default it uses the IP of the machine that provided the TFTP btw
| |
| 20:06 | johndoc: if you stick around other people can help you as well... a connection timeout sounds like either (A) the client is connecting to the wrong (A1) IP or (A2) port, or (B) the NBD isn't accessible because it's (B1) not started or (B2) it's firewalled
| |
| 20:07 | oh, or NFS
| |
| 20:08 | my root FS comes over NBD and my homes come over NFS, but you might have a different setup
| |
| 20:13 | <alkisg> johndoc: distro/version?
| |
| 20:14 | khildin has joined IRC (khildin!~khildin@ip-62-235-41-100.dial.scarlet.be) | |
| 21:09 | <johndoc> so I had to run (drive) 50 miles to plug a network cable in a wall, before I left I reset the client for the 5th time in a row. I just got back and it's booting now
| |
| 21:09 | the distro is ubuntu 14.04
| |
| 21:13 | server
| |
| 21:14 | I'm using NBD as it is the default for Ubuntu. I'm impartial to either at the moment since this is my first experience with NBD

| 21:57 | <alkisg> johndoc: nbd is fine, nfs currently has problems with overlayfs
| |
| 21:57 | OK if it's booting now, problem solved... :)
