Dec 01 16:47:03 raffo: same as on the beaglebone I presume, allowing users to connect via usb instead of ethernet Dec 02 01:03:50 hiya i have a question about persistence when booting from a microsd card Dec 02 01:04:32 i wrote the latest debian image to a micro sd card and then created another partition on the back half of the disk to use as storage Dec 02 01:04:57 why a second partition? Dec 02 01:04:59 Hello :) Dec 02 01:05:10 well i thought anything i did within debian would not be persisted Dec 02 01:05:20 like a live usb Dec 02 01:05:20 uhh, why would you think that? Dec 02 01:05:32 i thought it was going to behave like a usb Dec 02 01:05:40 live usb Dec 02 01:05:44 Anyone face "connection refused" for no reason? BBB with Ubuntu 16.04 on microSD Dec 02 01:06:11 but the thing is that's actually the behavior i want Dec 02 01:06:38 crumpets: those usb images you're thinking of are directly derived from "live cds", which were obviously necessarily read-only and therefore load the whole system into ram and run from that Dec 02 01:06:44 ya Dec 02 01:07:13 is something analogous possible on the beaglebone? Dec 02 01:07:43 i guess not directly since there isn't enough RAM to do that Dec 02 01:07:46 the beaglebone images are simply a prefab installed system, which you can either run directly from card or install onto eMMC Dec 02 01:07:55 gotcha Dec 02 01:08:23 if you want to use the full space of your card, I recommend removing the second partition and expanding the first partition to span the whole card Dec 02 01:08:42 I'll be glad if somebody can help me troubleshoot. I am new to BBB and I have spent 2 days and nights unsuccessfully trying to set up :( :( Dec 02 01:09:50 shiva_: I've never used ubuntu on a beaglebone, I don't think many people here have... how are you trying to connect to it? is the ubuntu system set up to accept any connections at all? (desktop ubuntu systems aren't, so I wonder) Dec 02 01:10:54 @zmatt I used "sudo dd if=bone-ubuntu-16.04.3-console-armhf-2017-10-12-2gb.img of=/dev/sdb bs=4M conv=fsync status='progress'" and then tried "sudo ssh 192.168.7.2" Dec 02 01:11:15 maybe you need to start sshd on the beagle ? Dec 02 01:11:31 crumpets: and you could make such an environment for the beaglebone, certainly. e.g. make the root filesystem a union of a squashfs image on the sd card and a tmpfs.... no idea why you'd want that though Dec 02 01:11:55 shiva_: does it even appear as usb network device at all? Dec 02 01:12:21 I have no idea how ubuntu for beaglebone is configured by default Dec 02 01:12:38 @zmatt I get two new network connections after holding down the button and powering the BBB Dec 02 01:13:49 and your computer obtains the ip 192.168.7.1 on one of them? Dec 02 01:14:00 also, why on earth would you do "sudo ssh" ? that makes absolutely zero sense Dec 02 01:14:28 It shows as Ethernet network (I am only connected to USB). And connection is refused for ssh to both 192.168.7.2 and 192.168.6.2. How do I check if my computer obtains 192.168.7.1 on one of them? Dec 02 01:14:37 and like crumpets said, maybe check if sshd is installed at all on the ubuntu system Dec 02 01:14:40 ip addr Dec 02 01:16:01 ip addr shows both 192.168.7.1 and 192.168.6.1. I do not know how I can check if sshd is installed without gaining access through ssh first. This is however the latest official ubuntu image Dec 02 01:17:05 @zmatt Dec 02 01:17:14 if you don't have display+mouse+keyboard connected to the beaglebone, why would you use ubuntu instead of debian? Dec 02 01:17:28 (actually, even if you do I would still wonder the same) Dec 02 01:17:53 just get the latest debian stretch iot image Dec 02 01:18:00 @zmatt I am going to install ROS. That is why I have Ubuntu. Dec 02 01:18:48 thanks zmatt. i think i will just use a tmpfs. reason being is that i need to generate some cryptographic keys in an extremely paranoid manner and don't want them written to disk ever Dec 02 01:19:18 crumpets: uhh, so don't write them to disk? (or, card) Dec 02 01:20:18 shiva_: so... why would you want ubuntu for that? Dec 02 01:21:03 ROS (Robot Operating System) is made for Ubuntu. It is not supported for other OSes Dec 02 01:21:08 @matt Dec 02 01:21:16 that's complete nonsense Dec 02 01:21:26 ros is packaged for debian stretch, you can simply apt-get install it Dec 02 01:23:18 hmm. Now it logged in Dec 02 01:23:20 fwiw I also use Ubuntu LTS on Beaglebone, for headless tasks (OpenVPN) and such. I'm sure you could use Debian also. I'm not using the same RCN image though, and not using the ethernet-over-USB stuff. Dec 02 01:23:38 My hypothesis is that it took a long time to boot Dec 02 01:23:46 About 10 minutes Dec 02 01:23:51 lol wow Dec 02 01:24:09 Of course I do not know much. I might be wrong Dec 02 01:24:25 Can I share my internet connection with BBB? @zmatt Dec 02 01:24:37 well if it's a complete desktop os with gui that's starting up, yeah it might be a bit slow Dec 02 01:25:32 thanks again ! later beaglers Dec 02 01:25:54 Thanks zmatt Dec 02 01:26:27 brtlin: does ubuntu still pull in plymouth as mandatory package, even on a completely gui-less machine? :P Dec 02 01:26:53 shiva_: and yes you can, but doing so is a bit tricky Dec 02 01:27:08 depends how it was built; mine doesn't Dec 02 01:27:51 brtlin: okay, at some point the mountall package had a dependency on plymouth Dec 02 01:27:55 no X at all, it's headless mostly, but will give you a getty on HDMI Dec 02 01:28:52 https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/556372 Dec 02 01:30:00 although it seems the claim is that plymouth is still useful on non-gui systems... if true that's news to me Dec 02 01:30:13 from shutdown to ssh-login takes about 25 seconds here Dec 02 01:30:33 I'm pretty pleased with my boot time... https://liktaanjeneus.nl/boot.svg Dec 02 01:31:11 yes - angstrom also is very fast, lots of effort went into that. but 26s != 10min Dec 02 01:31:27 never tried angstrom Dec 02 01:31:45 that's what is on the default image right? at least used to be Dec 02 01:31:55 uhh, many many ages ago I think Dec 02 01:32:03 ah... my bones are that old then Dec 02 01:32:11 it's been debian for as long as I've used beaglebones Dec 02 01:32:15 ok Dec 02 01:32:42 bed time for me... nn **** ENDING LOGGING AT Sat Dec 02 02:59:59 2017
