| 00:08 | <joe_sizlack> ah, sorry, you still around vagrantc?
| |
| 00:09 | <vagrantc> little bit
| |
| 00:09 | <joe_sizlack> is mounted as an aufs overlay on /rofs/. When I update my chroot, /rofs/ gets the new changes but / still has the old stuff
| |
| 00:09 | say I add a printer in /etc/cups in my chroot for instance
| |
| 00:09 | <vagrantc> reboot
| |
| 00:10 | <joe_sizlack> ahh
| |
| 00:10 | no way around it?
| |
| 00:10 | <vagrantc> don't know of one, but that's not saying a lot
| |
| 00:10 | <joe_sizlack> haha, you were supposed to be the aufs goto man :)
| |
| 00:10 | <vagrantc> the changes should get reflected automatically, though
| |
| 00:11 | unless they are files that were changed in the tmpfs layer
| |
| 00:11 | this is with NFS or NBD?
| |
| 00:11 | <joe_sizlack> nfs
| |
| 00:11 | on fat clients
| |
| 00:12 | <vagrantc> nbd would require a reboot for sure ... nfs *might* be able to get away without it
| |
| 00:12 | <joe_sizlack> right
| |
| 00:12 | one of the reasons I liked nfs over nbd
| |
| 00:12 | <vagrantc> joe_sizlack: if some of the modified files are in the /cow, you could try deleting those files from the /cow ... but i'm not even sure that's accessible anymore
| |
| 00:13 | <joe_sizlack> what does /cow do?
| |
| 00:14 | where does it fall in the scheme of / and it's relationship to /rofs/ I mean
| |
| 00:14 | I can access it
| |
| 00:14 | <vagrantc> that's where the tmpfs is
| |
| 00:15 | the / dir is an aufs filesystem composed of /rofs and /cow
| |
| 00:15 | the writes go to cow
| |
| 00:15 | <joe_sizlack> ah
| |
| 00:15 | <vagrantc> (Copy-On-Write)
| |
| 00:15 | <joe_sizlack> got it
| |
| 00:15 | well I hope to sort out a way to do this
| |
| 00:15 | <vagrantc> i suspect cups files get written, as there's ltsp-specific code that updates the printer settings from lts.conf
| |
| 00:16 | <joe_sizlack> well any conf really
| |
| 00:16 | <vagrantc> you could run something like puppet on the fatclients to apply changes locally
| |
| 00:16 | but clients would accumulate a bunch of changes over time
| |
| 00:17 | <joe_sizlack> i'd like to be able to chroot the chroot on the server and make common day to day changes
| |
| 00:17 | without having my guys reboot 'n all
| |
| 00:18 | I just finished my HA ltsp setup
| |
| 00:18 | about to spin it up tonight
| |
| 00:18 | it's gonna be rad
| |
| 00:22 | <vagrantc> nice
| |
| 00:24 | NFS is a lot more forgiving about reconnects to the server

| 19:28 | <gbaman> Ok, here is one for you guys... wifi...
| |
| 19:28 | Raspberrry Pi LTSP via wifi..
| |
| 19:29 | seeing as the pi already has the kernel on the SD card
| |
| 19:30 | Is that even possible alkisg and vagrantc?
| |
| 19:44 | bennabiy has joined IRC (bennabiy!~Thunderbi@24-181-55-79.dhcp.gnvl.sc.charter.com) | |
| 19:45 | <gbaman> ?
| |
| 20:00 | alkisg?
| |
| 20:23 | <alkisg> !arcfour | echo Hyperbyte:
| |
| 20:23 | <ltsp> Hyperbyte: arcfour: http://en.wikipedia.org/wiki/RC4 is an SSH cipher which is more than 2 times faster than the default aes128-ctr. To enable it, set LDM_SSHOPTIONS="-o Ciphers=arcfour128".
| |
| 20:23 | <gbaman> ?
| |
| 20:24 | <alkisg> gbaman: no need to ask specific persons, just mention your questions in the channel, and anyone that has something to say about them will do so...
| |
| 20:24 | <gbaman> :)
| |
| 20:24 | <alkisg> Personally I never had a pi, I don't plan on getting one because it's too slow, and I never plan on using wifi for thin clients because it's terribly slow
| |
| 20:25 | So slow + slow ==> unusable...
| |
| 20:25 | <gbaman> yes yes, but is it possible?
| |
| 20:25 | <alkisg> Sure
| |
| 20:26 | <gbaman> ok...
| |
| 20:28 | is it easy?
| |
| 20:36 | <effenberg> Pi as client or server?
| |
| 20:36 | <ogra_> lol
| |
| 20:36 | that was a rhetorical question i hope :)
| |
| 20:36 | <effenberg> ;)

| 20:40 | <gbaman> back
| |
| 20:40 | pi as a fat client

| 20:53 | adrianorg has joined IRC (adrianorg!~adrianorg@187.113.247.233) | |
| 20:54 | <Lumiere> pi doesn't really have enough power for a fat client
| |
| 20:54 | it really isn't a good option
| |
| 21:00 | <gbaman> it does, works perfectly fine
| |
| 21:02 | We basically want the functionality of LTSP, but also access to the local hardware on the pi
| |
| 21:03 | like GPIO pins
| |
| 21:03 | stuff like booting from a network image, so only 1 mast image
| |
| 21:03 | *master
| |
| 21:20 | We have it already booting fine and it runs at a similar speed to a normal pi, we are not loosing much speed if any
