Using a Mac for prepping the SD-card for an ODROID-C1+

Posted by jpluimers on 2018/02/12

Some notes based on The woods and trees of OpenSuSE on single-board computers – image abbreviations – and getting it installed using OS X « The Wiert Corner – irregular stream of stuff.

I needed to get Ubuntu on an ODROID-C1+ (as it looks like nobody is maintaining a current OpenSuSE for it).

Installing the ODROID-C1+ image using OS X

Download image

Download either of these (note that “minimal” is different from “mate minimal”; see https://www.youtube.com/watch?v=jOYWx_YToh8) from de.eu.odroid.in/ubuntu_16.04lts:

Put image on SD card

I installed on a 8 gigabyte SD card that revealed itself as /dev/disk1 using this diskutil command (via osx – List all devices connected, lsblk for Mac OS X – Ask Different [WayBack])

diskutil list

So this wrote the image to SD card in a sudo su - prompt:

targetDevice="disk1"
unxz --keep ubuntu-16.04-minimal-odroid-c1-20160817.img.xz; \
diskutil umount "/dev/${targetDevice}s1"; \
dd bs=1m of="/dev/r${targetDevice}" if=ubuntu-16.04-minimal-odroid-c1-20160817.img; \
sync; \
diskutil list; \
diskutil eject "/dev/${targetDevice}"

Boot and first time steps on Odroid

Use the default user and password that [WayBackODROID Forum • View topic – Ubuntu Minimal User / Password mentions:

odroid login: root
Password: odroid

From there, create a new user and add it to the sudo group (I used visudo to check the correct group for sudoers) :

adduser jeroenp
addgroup jeroenp sudo

And then hook it up to the network and get the IP address:

ifconfig

Now you can ssh into the odroid with user jeroenp and the password assigned to it. You can also perform a sudo su - to get to root level.

ssh and configure a few things

First of all, install etckeeper as it’s a life saver:

apt-get install etckeeper

This will install some other packages, but that’s OK; it will end suggesting you to enter email address, name and perform an initial commit:

Initialized empty Git repository in /etc/.git/

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'root@odroid.(none)')
etckeeper commit failed; run it by hand

Do that:

cd /etc
git config --global user.email "example@example.org"
git config --global user.name "Example User"
git commit -m "initial commit"

Now perform these steps:

  1. Change the root password
  2. Disable etckeeper daily autocommits
  3. Change the hostname
  4. Update/Upgrade/Distribution-upgrade
  5. Fix the cursor in console mode

Change root password:

# sudo su -
# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

Disable etckeeper daily autocommits involves one line in /etc/etckeeper/etckeeper.conf:

-#AVOID_DAILY_AUTOCOMMITS=1
+AVOID_DAILY_AUTOCOMMITS=1

Change the hostname; assuming your new host name is newHostName.

  1. edit /etc/hosts and replace the old hostname with newHostName
  2. Perform these commands:
    hostnamectl set-hostname newHostName
    exec bash
    hostname -f

Both the command prompt and the hostname output should show newHostName.

Update/Upgrade:

apt-get update
apt-get upgrade

Fix the cursor in console mode:

Somehow the Odroid C1+ does not support a blinking hardware text cursor.

On my research list: migrate from OpenSuSE SuSEfirewall2 to firewalld

Posted by jpluimers on 2018/02/11

The [WayBack] github.com/openSUSE/susefirewall2-to-firewalld is on my research list as right before going on holiday, upgrading broke my firewall configuration (:

Tumbleweed sometimes means living on the bleeding edge (which forces you to learn new things faster), so I knew things like this could be coming.

From the IRC chat at #opensuse-factory:
[5:25pm] <wiert> Something odd happened today: on an x64 system, I did zypper dist-upgrade, and now apache2 ports 80 and 443 are not reachable from the outside any more (only on localhost)
[5:25pm] <wiert> sysconf_addword /etc/sysconfig/SuSEfirewall2 FW_CONFIGURATIONS_EXT apache2
[5:25pm] <wiert> "apache2" already present
[5:26pm] <wiert> same fore apache2-ssl
[5:27pm] <wiert> sshd on the same line works fine. Apache runs.
[5:30pm] <wiert> What could I have broken? I went from 20180129 to 20180209
[5:30pm] Son_Goku joined the chat room.
[5:31pm] <wiert> Ah, I see that /etc/sysconfig/SuSEfirewall2.d/services/apache2 and /etc/sysconfig/SuSEfirewall2.d/services/apache2-ssl got deleted. Why?
[5:32pm] <simonizor> AFAIK, it was replaced by firewalld
[5:33pm] <simonizor> Both use iptables as a backend, so functionality should be relatively the same
[5:34pm] <wiert> Any URLs for migration tips?
[5:35pm] <wiert> For now I’ve done sysconf_addword /etc/sysconfig/SuSEfirewall2 FW_SERVICES_EXT_TCP 80
[5:35pm] <wiert> and sysconf_addword /etc/sysconfig/SuSEfirewall2 FW_SERVICES_EXT_TCP 443
[5:35pm] <wiert> now it “works” but I need to migrate one day.

OpenSuSE on ODROID? Maybe one day I get to researching that

Posted by jpluimers on 2018/01/01

For my research list (thanks Mariusz Fik ‏@Fisiu):

Actually: this was more of a reminder checking out if someone else by now has made OpenSuSE Tumbleweed builds for ODROID (:

Some notes on having static-web site owners upload their content over SFTP

Posted by jpluimers on 2017/12/14

Yes, there are still static web-sites. A long time ago, they were uploaded over FTP. Now many use more secure protocols.

So here are some links and notes to allow this on a Linux based host running OpenSSH.

I got to the above via these two links:

An alternative might be web-dave, but that would probably mean some hassle to separate uploading the site from accessing the site.

Re: [opensuse-factory] openssl dependency problems with snapshot 2017112

Posted by jpluimers on 2017/12/01

I had zypper being confused about the dist-upgrade between these snapshots:

< CPE_NAME="cpe:/o:opensuse:tumbleweed:20171125"
---
> CPE_NAME="cpe:/o:opensuse:tumbleweed:20171129"

It ran into this:

Problem: libopenssl-1_0_0-devel-1.0.2m-1.1.x86_64 conflicts with libopenssl-devel > 1.0.2m provided by libopenssl-devel-1.1.0g-1.1.noarch

Based on [WayBackRe: [opensuse-factory] openssl dependency problems with snapshot 2017112 after discussing with DimStar, I choose to have zypper dist-upgrade to perform

deinstallation of libopenssl-1_0_0-devel-1.0.2m-1.1.x86_64

Now all is fine.

Thanks Dominique a.k.a. DimStar!
