| 08:59 | <AndyGraybeal> 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 :)
| |
| 10:43 | Uzzi has joined #ltsp | |
| 10:43 | <Uzzi> Is it possible a wifi boot?
| |
| 10:45 | Uzzi 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...
| |
| 12:11 | alkisg 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 :)

| 13:04 | <johnny> 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..
| |
| 13:19 | ToncsiBit has joined #ltsp | |
| 13:21 | <AndyGraybeal> i might be thinking the wrong way anyhow. i think that all i need is NFSv4 acl's

| 13:36 | <markit> 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.

| 19:29 | <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
