Debian¶
Some notes from my Debian 5.0 (Lenny) to 9.0 (Stretch) server experiences.
Hostname¶
Set hostname for IPv4 and IPv6 on loopback interface:
hostname=foo
domain=felixhummel.de
fqdn=$hostname.$domain
cat <<EOF > /etc/hosts
127.0.0.1 localhost
127.0.1.1 $hostname $fqdn
::1 localhost ip6-localhost ip6-loopback $hostname $fqdn
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
EOF
echo $hostname > /etc/hostname
hostname -F /etc/hostname
exec $SHELL
hostname
hostname -f
python -c 'import socket; print socket.getfqdn()'
python3 -c 'import socket; print(socket.getfqdn())'
https://github.com/saltstack/salt/issues/36619 “grains.fqdn value is difficult to rely on”

Git 1.9 on Debian Wheezy¶
apt-get -t wheezy-backports install git
echo 'deb http://cloudfront.debian.net/debian wheezy-backports main' \
>> /etc/apt/sources.list
Debian Locale¶
Error:
perl: warning: Falling back to the standard locale ("C").
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.utf8"
are supported and installed on your system.
Fix:
sudo dpkg-reconfigure locales
Add Another Locale¶
E.g. for German UTF-8:
grep de_DE.UTF-8 /usr/share/i18n/SUPPORTED
echo "de_DE.UTF-8 UTF-8" >> /var/lib/locales/supported.d/local
dpkg-reconfigure locales
