| azend | I may be stuck with the job of setting up a lab of 18 laptops | 00:16 |
|---|---|---|
| azend | any advice on setting up linux for cloning? | 00:17 |
| BobJonkman1 | azend Check out Clonezilla | 01:19 |
| BobJonkman1 | There's a server component that does multi-cast. Boot each laptop from a USB stick (or even from PXE), when they're all ready select "go" on the server, and they all chug along at the same rate. | 01:20 |
| BobJonkman1 | I used to update labs at The Working Centre (2 labs, 16 workstations each) with that. | 01:21 |
| BobJonkman1 | Paul Nijjar set up the server end; you may want to ask on the KWLUG mailing list where he hangs out | 01:21 |
| azend | Cool | 01:23 |
| azend | yeah, I've used Clonezilla before but I've only ever used the one to one tools | 01:24 |
| azend | I guess I'm more asking if there is anything I should know in terms of hiccups when you clone ubuntu/linux to another machine | 01:24 |
| azend | windows isn't great at cloning either | 01:25 |
| BobJonkman1 | The linux kernel is a remarkable beast. | 01:25 |
| azend | you can clone it fine but all of the security keys stay the same | 01:25 |
| azend | so if you crack one machine, you crack them all | 01:26 |
| BobJonkman1 | I've pulled a hard drive out of one P4 single core machine and put it into a P5 four core with more RAM and a better video card and it just worked | 01:26 |
| azend | very cool | 01:26 |
| BobJonkman1 | When I cloned WIndows we had a license that allowed duplicates (some kind of low-cost institutional license) | 01:27 |
| BobJonkman1 | There's also a way to set up a central license server | 01:27 |
| BobJonkman1 | The biggest problem is that after the clone you have to bang each machine to change hostname | 01:28 |
| BobJonkman1 | Of course, you can do that with a script, maybe based on MAC address or DHCP address. | 01:28 |
| BobJonkman1 | Also, since we had two labs, on one we had to change things like default printer definition | 01:28 |
| BobJonkman1 | But on Linux if you're not worried about customizing each box then you only have to worry about hostname | 01:29 |
| azend | yeah, I'm not really worried about that | 01:30 |
| azend | I figure I could just make the host names "DIYODE-<last two bytes of mac address>" | 01:30 |
| azend | ie. DIYODE-3E4F | 01:31 |
| BobJonkman1 | Before we had the multi-cast server I just pulled the Clonezilla images off my laptop. Took more bandwidth (and was much slower), but easy to do | 01:31 |
| azend | how much resources does the server take | 01:31 |
| azend | can you run it on a raspberry pi with a hard drive? | 01:32 |
| BobJonkman1 | Right, so set the hostname to "unconfigured", then have a bootup script check for that and change if necessary | 01:32 |
| azend | or an nslu2? | 01:32 |
| BobJonkman1 | rpi will probably work. | 01:32 |
| BobJonkman1 | The multi-cast doesn't take nearly as much bandwidth. But images can be big, so you need storage. But you can probably keep an image on a 16 GB sdcard, so a rpi should be oK | 01:33 |
| * BobJonkman1 doesn't know what an nslu is | 01:34 | |
| BobJonkman1 | Gotta go. I'm changing the faucet on the kitchen sink. I hate plumbing, and it's already taken all afternoon. | 01:35 |
| azend | It's an old linksys network appliance | 01:35 |
| azend | https://en.wikipedia.org/wiki/NSLU2 | 01:35 |
| azend | It is a device that you plug hard drives into and it becomes your nas | 01:35 |
| azend | but it became famous because you could reflash the firmware with debian | 01:35 |
| azend | and could run whatever you wanted | 01:36 |
| BobJonkman1 | You can boot each laptop with Clonezilla and just pull the image from any network accessible storage. So that nslu should work | 01:36 |
| azend | we used one at hillside a few years ago to act as a wifi portal and web chat server | 01:36 |
| azend | very cool | 01:36 |
| BobJonkman1 | And if it runs Debian then you can run the clonezilla server (which isn't called "clonezilla server") | 01:37 |
| * BobJonkman1 goes to look for the web site | 01:37 | |
| BobJonkman1 | http://clonezilla.org/clonezilla-SE/ | 01:39 |
| BobJonkman1 | The server was DRBL | 01:39 |
| azend | I'm there thanks | 01:39 |
| BobJonkman1 | But Paul Nijjar set it up. | 01:39 |
| azend | dribble is a terrible name :P | 01:39 |
| BobJonkman1 | I seem to recall he had some issues before it worked | 01:39 |
| BobJonkman1 | I pronounce it dur-bull | 01:40 |
| azend | that makes more sense | 01:40 |
| BobJonkman1 | (because dribble is a terrible name) | 01:40 |
| azend | It sounds like a dog salivating on all of your machines | 01:40 |
| BobJonkman1 | Anyway, I'm off to do some recreational plumbing | 01:40 |
| azend | I love recreational plumbing! :_ | 01:41 |
| azend | :) | 01:41 |
| azend | It's like plumbing but with water everywhere | 01:41 |
| azend | not to say regular plumbing isn't the same | 01:42 |
| azend | but with recreational plumbing it's intentional! | 01:43 |
| BobJonkman1 | As soon as I twisted the knob on the shutoff valve it started to spray water. | 01:43 |
| BobJonkman1 | And things got worse from there | 01:43 |
| * BobJonkman1 is procrastinating | 01:43 | |
| * BobJonkman1 hates plumbing | 01:44 | |
| BobJonkman1 | The only up side to having to do this plumbing is that I don't have to do the dishes. | 01:44 |
| BobJonkman1 | But as soon as the plumbing is done then the dishes can be done too. | 01:44 |
| BobJonkman1 | So the more I put it off... | 01:44 |
