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.

Related:

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.

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!

SuSEconfig is dead…

Posted by jpluimers on 2017/11/30

SuSEconfig has been dead for a while, but still indexed at quite a few of the official sites stressing the importance to use it.

It used to apply the configuration in /etc/sysconfig to the system.

The rationale for removal was simple:

Let’s remove all SuSEconfig scripts since only YaST calls SuSEconfig but other tools like rpm and zypper do not call it.

If scripts are needed, they need to be invoked as part of the postinstall.

Now most services either know to directly handle the configuration data there (and apply it during reload/restart/start of the service), or have a tool (like postfix now has /usr/sbin/config.postfix) to apply the settings.

MX Backup – Postfix Email Server | samhobbs.co.uk

Posted by jpluimers on 2017/11/09

Interesting as it has steps for both OpenSuSE and Debian each well suited for running on a Raspberry Pi.

[WayBackMX Backup – Postfix Email Server | samhobbs.co.uk

It seems postfix is a lot easier to configure than sendmail so I already like it.

First I need to read a bit more in Postfix greylisting.

I’ll need to catch up on Sam’s other parts with the postfix tag as well:
