| 01:07 | <vagrantc> jammcq: high five
| |
| 01:07 | <jammcq> hey
| |
| 01:07 | awesome success today with kiosk mode
| |
| 01:08 | <vagrantc> ah, good.
| |
| 01:08 | <jammcq> I gave a demo to my customer and they are quite impressed
| |
| 01:08 | as am I
| |
| 01:08 | remember last night, I was having the permission problem running X ?
| |
| 01:08 | odd thing. /usr/bin/X is setuid, but /usr/bin/Xorg isn't
| |
| 01:08 | Parker955_Away is now known as Parker955 | |
| 01:09 | <jammcq> so I'm wondering if you are running /usr/bin/X and I'm running /usr/bin/Xorg
| |
| 01:09 | dunno why i'd be running something different from you
| |
| 01:09 | anyway, I added the setuid bit to Xorg and the perms problem went away
| |
| 01:09 | BUT... a new problem appeared. Xorg doesn't like using a -config with a file that has a leading '/'
| |
| 01:10 | it thinks that's a security problem. So, I had to modify ${CHROOT}/usr/share/ltsp/screen-session.d/XS00-setvars to remove the leading '/' on the config file

| 01:28 | <vagrantc> jammcq: oh, that's interesting.
| |
| 01:28 | <jammcq> yeah, dunno why you didn't have the same problem
| |
| 01:29 | <vagrantc> well, i didn't use X_CONF or any features that require it ... for the latter part of your problem.
| |
| 01:29 | <jammcq> neither did I
| |
| 01:29 | <vagrantc> it shouldn't need a config file at all...
| |
| 01:30 | <jammcq> I didn't specify anything in the lts.conf file, other than SCREEN_07=kiosk
| |
| 01:30 | and KIOSK_EXE, KIOSK_WM
| |
| 01:31 | could be 2 issues: 1) didn't really need a config file. 2) If it does use a config file, needs to NOT have a leading '/'
| |
| 01:31 | but I found another oddity.
| |
| 01:31 | my chroot is called /opt/ltsp/kiosk_amd64
| |
| 01:31 | but when the client boots, it tries to grab /var/lib/tftpboot/i386/lts.conf
| |
| 01:32 | I was expecting it to look in kiosk_amd64 for the lts.conf file
| |
| 01:32 | adrianorg_ has joined IRC (adrianorg_!~adrianorg@187.113.246.239) | |
| 01:33 | <jammcq> but it seems like it would make more sense to look for /var/lib/tftpboot/lts.conf, without the arch in the path
| |
| 01:33 | <vagrantc> ah, root can specify the leading / ... but in kiosk mode you're not running as root...
| |
| 01:33 | <jammcq> ah, right
| |
| 01:34 | turns out, the cwd is /, so removing the leading '/' from the path works
| |
| 01:34 | <ball> Does ltsp have to be netbooted?
| |
| 01:34 | ...or could I stick it on a flash drive?
| |
| 01:35 | <jammcq> I don't think it supports flash drive booting, although I'd like it if it did
| |
| 01:35 | <Enslaver> Gpxe support local flash booting?
| |
| 01:36 | <vagrantc> it's actually possible to boot off of a flash drive, but that requires some tinkering.
| |
| 01:36 | not really hard or anything
| |
| 01:37 | <ball> Hmm... I'll have a poke around then.
| |
| 01:37 | <jammcq> well... theres two things. 1) the kernel 2) the root fs
| |
| 01:37 | <vagrantc> a more important question is why would you want to? :)
| |
| 01:37 | not that there aren't valid use-cases...
| |
| 01:38 | <jammcq> in my case, as a kiosk, I really have no need for a server at all
| |
| 01:38 | <ball> Well, aside from the place where I want to use it the right way, I'm also thinking of using it at another place, where it'd take some shoehorning to get it into the network.
| |
| 01:38 | <Enslaver> Technically don't we boot off flash anyway? I mean initram is just non persistent memor
| |
| 01:39 | <vagrantc> flash/usb/hard drive/whatever
| |
| 01:39 | all the same as far as LTSP is concerned.
| |
| 01:39 | <jammcq> Enslaver: yeah, but turn the machine on and have it find the kernel and the rootfs
| |
| 01:39 | <Enslaver> Just write init rd to dd
| |
| 01:39 | <jammcq> it really just ends up being a little tiny distro
| |
| 01:40 | but you need a bootloader
| |
| 01:40 | so what do you use instead of the pxelinux.0? grub?
| |
| 01:41 | <Enslaver> Tiny core Linux :)
| |
| 01:41 | <jammcq> do you format the flash disk as 2 filesystems? one to hold grub and the kernel, and the other to hold the root fs?
| |
| 01:41 | so while it's not impossible, there's a bit of work to do, to make it all happen
| |
| 01:41 | <Enslaver> I would
| |
| 01:42 | why not this, install a very small linux distro on a flash drive, nfs/nbd mount remote server partition, union that partition with a cow overlay and pivot
| |
| 01:43 | thats basically all my overlay does in initram
| |
| 01:43 | <jammcq> but then you are back to using nfs/nbd
| |
| 01:43 | from a server
| |
| 01:43 | where I think flash makes sense is to do a wireless workstation
| |
| 01:44 | you can't PXE boot via wireless
| |
| 01:44 | <Enslaver> all we can do until libpam_ssh is ready
| |
| 01:44 | <jammcq> huh?
| |
| 01:44 | dunno what libpam_ssh has to do with it
| |
| 01:44 | <Enslaver> due to the lack of a ldm port
| |
| 01:44 | well, not lack of, ease of portablity
| |
| 01:45 | <jammcq> ldm comes way after the kernel+initramfs+rootfs stuff
| |
| 01:45 | <Enslaver> You lack a auth protocol, the small linux can do everything except that
| |
| 01:45 | I think thats where berryterminal is struggling atm
| |
| 01:46 | although ive never played much with wireless pxe, is there something out that works securely?
| |
| 01:46 | <jammcq> there is no wireless pxe
| |
| 01:47 | at the pxe level, you don't have enough of an operation system to do the wireless stuff
| |
| 01:47 | s/operation/operating/
| |
| 01:48 | <Enslaver> probably etherboot tho?
| |
| 01:48 | <jammcq> no
| |
| 01:48 | etherboot/pxe doesn't matter
| |
| 01:48 | you don't have enough OS to do the wireless stuff
| |
| 01:49 | <Enslaver> even if they had hw support?
| |
| 01:49 | <jammcq> hw support?
| |
| 01:49 | etherboot is tiny, like less than 32k
| |
| 01:50 | there's certainly no room in there for doing anything with a wireless card
| |
| 01:50 | wired is easy. a driver for wired card is very little code
| |
| 01:50 | <vagrantc> Enslaver: ldm works on arm just fine.
| |
| 01:51 | there's no portability issue there...
| |
| 01:52 | <Enslaver> Can i have my pi release plz :)
| |
| 01:52 | i'll be your friend
| |
| 01:52 | on facebook
| |
| 01:52 | <jammcq> hmm, sounds creepy
| |
| 01:52 | <Enslaver> (creepy would be to let him know i already am)
| |
| 01:53 | * Enslaver winks at vagrantc. | |
| 01:53 | <jammcq> vagrantc on facebook... that'd be funny
| |
| 01:53 | <vagrantc> Enslaver: pi release?
| |
| 01:54 | <Enslaver> si si
| |
| 01:54 | <vagrantc> como?
| |
| 01:54 | <Enslaver> el pi
| |
| 01:55 | poor fever
| |
| 01:55 | <vagrantc> no entiendo, amigo.
| |
| 01:55 | <Enslaver> que?
| |
| 01:55 | tu es bueno ;)
| |
| 01:55 | <vagrantc> no conoce "pi release"
| |
| 01:55 | <Enslaver> love u long time?
| |
| 01:55 | <vagrantc> no conozco
| |
| 01:56 | * vagrantc yawns | |
| 01:56 | <Enslaver> Las tango el gato los pantalones
| |
| 01:56 | vivia pi!
| |
| 01:57 | * Enslaver dances | |
| 01:57 | <vagrantc> quieres un HOWTO para el Raspberry PI?
| |
| 01:58 | <Enslaver> http://www.berryterminal.com/doku.php/berryboot
| |
| 02:00 | <vagrantc> berryboot is slightly interesting.
| |
| 02:00 | but i prefer to build it out of Debian's armhf port...
| |
| 02:01 | although the bootloader is something i'd like to hack up
| |
| 02:01 | <Enslaver> more like a raspian with that bootloader?
| |
| 02:01 | I thought berryterm was based on deb?
| |
| 02:03 | <vagrantc> doesn't look like it to me.
| |
| 02:03 | looks more like openembedded or something
| |
| 02:03 | ah right, not debian's armhf port, raspbian ...
| |
| 02:04 | out of all people, i shouldn't fail to make that distinction. hah!
| |
| 02:05 | <Enslaver> Don't worry vagrant, there is a fedora port for the pi!
| |
| 02:05 | <vagrantc> i don't need to worry about fedora, it's true :)
| |
| 02:06 | <warren> I'm glad I'm not the lone crazy one here anymore.
| |
| 02:06 | <Enslaver> debatable
| |
| 02:06 | <vagrantc> sing us a song, warren!
| |
| 02:07 | or not...
| |
| 02:07 | <Enslaver> There once was a man from nantucket, he invented fedora so he could
| |
| 02:07 | lol
| |
| 02:07 | howdy warren

| 02:36 | <Enslaver> There some open source software that will auto-connect to a any open-wifi it sees?
| |
| 02:36 | like what autoap does for dd-wrt

| 03:18 | <baptiste> scripting something with wicd-cli, maybe?
| |
| 03:19 | I've never used it but it may help
| |
| 03:39 | <Enslaver> Never heard of that one, trying a script with network manager now
| |
| 03:44 | <baptiste> wicd looks less complex
| |
| 03:47 | at least, the GUI veersion is smaller than network manager, if you want something a bit lighter and easy but with less features
| |
| 03:48 | it has wicd-curses client to connect from a terminal/ssh session the easy way
