morning everyone
09:12
<Trixboxer>
evening :)
09:12
Anyone using konversation in ltsp ?
09:14
I dont know why but the setting are not getting persistent after the user logs out from the client screen (fat-client)
09:18
<alkisg>
Where does it store its settings? In $HOME or in some obscure /var/* directory?
09:19
<Trixboxer>
after scanning I think its $HOME but not sure
09:19
<alkisg>
Urm wait, so if the user logs out and then logs back in on the same fat client without rebooting, the settings are lost?
09:20
<Trixboxer>
yes
09:20
<alkisg>
Is that with sshfs or nfs?
09:20
(/home ?)
09:20
<Trixboxer>
nbd
09:20
i think that is sshfs
09:21
<alkisg>
Right... maybe konversation has problems with it. Try running it from the command line and watch for any errors/warnings
09:22
<Trixboxer>
hmm ok wll try
10:00
alkisg: The message pops up as could not lock file
10:00
<alkisg>
Trixboxer: see the paragraph about some apps using locks which doesn't work with sshfs on this wiki page:
10:00
!fatclients
10:00
<ltspbot`>
alkisg: "fatclients" :: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
10:00
<alkisg>
If konversation is one of them, either a workaround or NFS would be needed
10:01
<Trixboxer>
:9 again NFS
10:01
I think I must take it seriously and fire it up :)
10:19
<AndyGraybeal>
i've been thining about nfs also.
10:19
NFSv4, yes?
10:23
<Trixboxer>
yeah I'm just checking the link provided by alki**
10:38
<AndyGraybeal>
is anyone running openindiana with ltsp? or given it any thought? i might try to do it.. but i know i will fail misrably if it's too different than ubuntu :)

<Uzzi>
Is it possible a wifi boot?
10:45Uzzi has quit IRC
10:52
<AndyGraybeal>
uzi, yes, but your gone :)
10:53
<Trixboxer>
AndyGraybeal: Have you tried ?
10:53
I started working for it using gPXE but left due to some other emergencies
10:53
<AndyGraybeal>
no, but i read all you need is a wifi router hooked up to your ethernet
10:54
i think i asked in here a while back about it, and i read about it too
10:55
like you get yourself a wap and tie it to your ethernet port on your laptop and then you boot like that.
10:55
<Trixboxer>
I dint get that.. I meant booting a fat client on a wifi enabled laptop for a *roamig* profile :0
10:55
:)
10:55
<AndyGraybeal>
i don't think you can boot directly off the interface, because most interfaces don't support PXE booting
10:56
that's why oyu need to boot off the ethernet port tied to the wap
10:56
<Trixboxer>
yeah but few readings conformed me that I can do it
10:56
though I dont have a evidence yet
10:56
<AndyGraybeal>
oh i'm sure there are interfaces out there that can do it.
10:56
it would be nice to know which ones :)
10:56
<Trixboxer>
the thing is called a kernel booting kerne
10:56
<AndyGraybeal>
okay, then i'm sure you know more about this than i do.
10:57
<Trixboxer>
you can do it on any interface, I think u just need a usb key with proper kernel and driverfs
10:57
drivers*
10:57
<AndyGraybeal>
usb key?
10:57
<Trixboxer>
and then that kernel boots up another kernel by removing self .. technically called kexec
10:57
usb drive
10:57
<AndyGraybeal>
ah ok
10:58
<Trixboxer>
small usb pen drive of few kb (if available ;)
10:58
<AndyGraybeal>
yes, i'm not that smart, carry on :)
10:58
<Trixboxer>
aah common .. I just want to share what I come to know
10:59
<AndyGraybeal>
i said, go ahead :)
10:59
please share, i have no idea about a kernel removing itself :)
11:00
<Trixboxer>
yeah there is a function called kexec which loads another kernel on top of existing kernel and the new kernel removes the old one
11:01
old kernel boots with wifi drivers and details of wifi connections are passed to kernel over its boot command
11:01
then new one is downloaded from the dhcp and you know the rest of the story :)
11:01
<AndyGraybeal>
but doesn't the wifi port still need to be able to pxe boot?
11:02
but nevermind, i'm sure i just don't know enough, and embarress myself by asking such a question.
11:03
<Trixboxer>
hmm I may be misunderstood the question but as I recall its said that the kernel is instructed to boot up the new system in all possible ways such as etherboot, wifi, cdrom, hdd etc
11:03
if you read XEN, it works near same
11:04
<AndyGraybeal>
i've been using kvm/libvirt
11:04
<Trixboxer>
dom0 is a VM on top of a bare os
11:04
<AndyGraybeal>
so i haven't read xen
11:06
<Trixboxer>
Once I get free I'll give a try to wifi boot..
11:34
<AndyGraybeal>
i know it's o/t but i'm reading about zfs and zpool
12:01
<alkisg>
Why zfs and not btrfs?
12:02
I'm not sure that wireless booting makes much sense for fat clients, due to bandwidth constrains. I think it'd be much better if the whole chroot was written on the usb stick...
12:11alkisg has quit IRC
12:36
<johnny>
AndyGraybeal, not sure why you would bother with zfs unless you're using solaris
12:36
btrfs will win on linux
12:37
<AndyGraybeal>
btrfs ? i've never heard of it
12:38
i was thinking about using openindina or freebsd but i will look into btrfs
12:38
thank you
12:38
<johnny>
it's sponsored by oracle
12:38
before they bought sun obviously
12:38
oracle seems to be letting solaris die
12:38
which i'm happy with, but i'm sure all the solaris people aren't
12:39
sure openindiana still exists, but i doubt it's going anywhere with the lip service oracle is giving it
12:39
there's no reason to use solaris unless you're paying for it it seems
12:39
<AndyGraybeal>
that's pretty negative thoghts .
12:47
<Trixboxer>
Good night guys :)

AndyGraybeal, ?
13:04
loook up the history of the open solaris board since oracle bought sun
13:06
<AndyGraybeal>
well, i was hoping that openindiana would slowly gain strength
13:14
<johnny>
not exactly sure how it will ever match linux
13:19
<AndyGraybeal>
okay, well i don't know..

i might be thinking the wrong way anyhow. i think that all i need is NFSv4 acl's

alkisg: hi, I've a dubt about some detail of disabling nbd_proxy in maverick
13:36
do you have 2 minuts for me?
13:36
or anyone else that knows the matter :)
13:36
in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
13:37
I've "append ro initrd=initrd.img quiet splash nbdport=2000"
13:37
so there is the "nbdport=2000" parameter
13:37
when you say to add in /etc/ltsp/ltsp-update-image.conf
13:37
BOOTPROMPT_OPTIONS="quiet splash nbd_proxy=false"
13:38
have you missed that nbdport=2000 parameter, or does not matter?
13:38
(bottom of https://bugs.launchpad.net/ltsp/+bug/589034 )
13:42
<johnny>
it's not necessary
13:42
i do'nt think..
13:45
<markit>
wondering why to disable nbd-proxy the parameter is named nbd_proxy
13:48
<johnny>
in case the default option changed to false, then you would change it to true to enable it..
13:53
<alkisg>
markit: nbdport is added automatically by ltsp-build-client and by ltsp-update-image --force, no need for it to be in a configuration file. About the underscore in nbd-proxy, usually the kernel parameters are with underscores.

<crazed>
hm
19:29
is there a way to do local apps firefox without a proxy
19:29
i guess not really
19:29
<vagrantc>
use NAT
19:30
<crazed>
well i have LTSP servers that are allowed out to the internet
19:30
and the thin clients are on the same network
19:30
<vagrantc>
configure your firewall to NAT traffic, or run it on a routeable network
19:30
<crazed>
but firewall stops them from going out
19:30
security wants to limit points of exit
19:30
<vagrantc>
that's your firewall, not LTSP
19:30
<crazed>
yeah i know
19:31
so firefox running on ltsp works just fine, it's that i want the added performance from running it locally
19:31
so i'd need some sort of proxy service at that point
