[00:56] [FuriousGeorge] hey all
[00:56] [FuriousGeorge] one of my clients wants me to run kb / mouse /vid cables from the server room to an adjacent room where they want to use the server directly
[00:57] [FuriousGeorge] i don't see why not, but it just feels wrong
[00:57] [FuriousGeorge] can anyone talk me down?
[01:00] [appiah] for server console access? sure why not?
[01:01] [appiah] many places has a console room where you can access your servers without entering the server room
[01:04] *** Lns wants a console room
[01:05] [appiah] but it can be nice once in a while to enter the server room and try to work with all that noise
[01:06] [Lns] I have 4 rackmount servers right by me every day
[01:06] *** frederickjh wants a server room too 8-)
[01:06] [Lns] it gets old =p
[01:07] [Lns] FuriousGeorge, console access is always really good (for when you need bios/etc. access, or if the server doesn't come up right)..but other than that you can always just use an x server anywhere on the network to get to her
[01:11] [Lns] I was just talking to my wife yesterday about wanting a IP-KVM... *drool*
[01:16] [FuriousGeorge] Lns: of course i have console access, and i don't see what damage my users could do, but I was just nervous about it

[01:57] [Briareos1] will nbd make a swapfile for every client - or only of the client runs out of ram / needs it?
[02:00] [alkisg] If nbd_swap is enabled, then it will make a swap file for every client. By default it's disabled, unless the client has < 48 ram.
[02:01] [Briareos1] alkisg, strange - i just followed the guide to set it up, booted a thin client - but theres only one file in /tmp that _is not_ the size i provided nbdswapd.conf
[02:01] [alkisg] What guide?
[02:02] [Briareos1] https://help.ubuntu.com/community/UbuntuLTSP/EnableNBDSWAP

[02:04] [Briareos1] yes
[02:05] Egyptian[Home] (~EgyptianH@62.117.46.249) joined #ltsp.
[02:05] [alkisg] Enter those commands, and upload the result to pastebin:
[02:05] [alkisg] cat /var/lib/tftpboot/ltsp/*/lts.conf
[02:05] [alkisg] cat //etc/ltsp/nbdswapd.conf
[02:05] [alkisg] *with one slash, not two...
[02:05] [Briareos1] SIZE=1024
[02:05] [Briareos1] for the second
[02:06] [Briareos1] NBD_SWAP = True
[02:06] [Briareos1] for the first
[02:07] [alkisg] You need a [Default] on top of that
[02:07] [Briareos1] and the date of the tmp-file is also not current - so it's probably not related to the setup i just did :)
[02:07] [alkisg] [Default]
[02:07] [Briareos1] ah
[02:07] [alkisg] NBD_SWAP=True
[02:07] [Briareos1] is it normal that the file didn't exist at all?
[02:07] [alkisg] Yes
[02:07] [Briareos1] i had to create it ...
[02:07] [Briareos1] ok
[02:07] [alkisg] How much RAM do your clients have?
[02:08] [Briareos1] not too sure, but i think the lowest could even be 128
[02:08] [alkisg] And, why do you want such a big swap space?
[02:08] [Briareos1] or 256 is possible as well
[02:08] [alkisg] And, are you using localapps?
[02:08] [Briareos1] well ... i just thought for testing i can make it that big - as the space is available anyways
[02:09] [Briareos1] localapps - not yet ... i wanted to take all the hints i got here yesterday and run them down sequentially (if that's proper english :))
[02:09] [alkisg] And, do your clients have local disks? if so, you could make a swap partition in them...
[02:09] [Briareos1] most of them do.
[02:09] [alkisg] OK, my advice is:
[02:10] [alkisg] With 128 or 256 RAM, you can't use localapps, no matter how much swap space you make
[02:10] [alkisg] So you don't really need a big swap space
[02:10] [alkisg] If your clients have a local disk, and you're able to make an e.g. 512 MB swap partition, do that
[02:11] [Briareos1] i could switch all clients to ~1 GB ram
[02:11] [Briareos1] okay, can you hint me any documents on the local swap partition?
[02:11] [alkisg] If you can put more RAM in the clients, then you'll be able to use localapps or even fat clients
[02:11] [Briareos1] btw: I put the [Default] there - and still no new tmp-file
[02:12] [alkisg] I assume they also have CD drives? You can boot them with an ubuntu live cd, and use gparted to make a swap partition...
[02:12] [Briareos1] ah will ltsp automatically notice a normal swap partition on the client?
[02:12] [alkisg] I think an extra line is needed - just a minute...
[02:13] [alkisg] USE_LOCAL_SWAP=True
[02:13] [alkisg] (in lts.conf)
[02:13] [Briareos1] very interesting
[02:14] [alkisg] If you have local disks, there's no reason to use nbd_swap
[02:14] [Briareos1] but for a quick solution without the need to configure all the clients it'd be
[02:16] [Briareos1] there are about 15 users on it and they're complaining about a lack of speed :)
[02:16] [alkisg] Well swapping won't get you speed :)
[02:16] [Briareos1] well ... one is not complaining - he's got the strongest clientmachine
[02:17] [alkisg] swap == stability, avoiding crashes etc. It doesn't offer any speed at all.
[02:17] [Briareos1] okay ... that would be a start
[02:17] [Briareos1] hangs also occur frequently
[02:17] [Briareos1] :)
[02:18] [Briareos1] what could be another reason for the nbd_swap not to work? is there anything else i can check?
[02:23] [alkisg] You rebooted the client?
[02:24] [Briareos1] several times
[02:24] [alkisg] Append these on lts.conf:
[02:24] [alkisg] SCREEN_02=shell
[02:24] [alkisg] SCREEN_07=ldm
[02:24] [Briareos1] ldm? is it ldm not gdm?
[02:24] [alkisg] Reboot the client. Press alt+ctrl+f2. A terminal will appear. On that, enter: getltscfg -a
[02:25] [alkisg] Yes, it's ldm
[02:25] [alkisg] The "LTSP Display Manager"
[02:25] [Briareos1] somehow i was thinking it was changed to gdm at some point of the ltsp development ...
[02:26] [Briareos1] anyways i'll try that
[02:26] [Briareos1] one moment
[02:28] [alkisg] Also, the best thing you can do for speed, is to enable LDM_DIRECTX. See the lts.conf man page for a description of the speed vs security story.

[02:58] [Briareos1] could it be that the "/var/lib/tftpboot/ltsp/i386/lts.conf" isn't used at all? how can i check that?
[03:04] Egyptian[Home] (~EgyptianH@62.117.46.249) joined #ltsp.
[03:09] [alkisg] Briareos1: if you put "SCREEN_02=shell" and that didn't work, then probably the clients don't get lts.conf at all.
[03:09] [alkisg] To verify that, open /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default, and add "break=init" at the end of the kernel line
[03:09] [alkisg] Then reboot a client. It should spawn a shell while booting.
[03:09] [alkisg] In that shell, enter: cat /etc/lts.conf
[03:10] [alkisg] If you see your lts.conf there, the clients get it, otherwise they don't.
[03:10] [alkisg] Other than typos, one reason for the clients not to get lts.conf is if the dhcp server doesn't send the "filename" field to the ipconfig client.
[03:16] [Briareos1] ok i'll check the dhcp - cuz i get "no such file or dir" for the cat

[04:40] [isojussi] it has worked before but when i updated from 8.04-->9.10 I can't edit/create user accounts from clients. The button which allow to modify user accounts is greyed out

[04:43] [isojussi] I can make/edit user accounts in server, but other admin has no physical access to it, so it would be great that he could manage them from clients
[04:45] [ogra] sadly that wont work due to the new policykit/consolekit architecture ...
[04:46] [isojussi] is there a reason to that?
[04:46] [ogra] policykit forbids people that are not on the local to change user credentials
[04:46] [ogra] i *think* you can configure it but i'm not sure
[04:47] [ogra] there has been a graphical policykit tool, noit sure it still exists, i'd do a test install and play with it
