+= how to add a new machine =
-Note: this is partially obsolete now that we have [[puppet-setup|puppet]]. We should probably update/rework some parts.
+Note: this has recently been changed to rely more on [[puppet|howto/puppet-setup]]. If stuff breaks fix it.
-** Warning: This procedure has not been tested since being moved to the wiki. Beware. **
-* install ssh if it isn't there already
+* some initial stuff:
{{{
- apt-get install ssh
+ apt-get install --no-install-recommends ssh vim &&
+ echo -n > /etc/environment &&
+ echo -n > /etc/default/locale &&
+ apt-get install --no-install-recommends dialog &&
+ echo "debconf debconf/priority select high" | debconf-set-selections &&
+ echo "debconf debconf/frontend select Dialog" | debconf-set-selections
}}}
-* make apt sane
+* unless we want to keep it:
{{{
- echo 'Acquire::PDiffs "false";' > /etc/apt/apt.conf.d/local-pdiff
- echo 'APT::Install-Recommends 0;' > /etc/apt/apt.conf.d/local-recommends
+ dpkg -l postfix | grep '^ii postfix' && (dpkg --purge postfix && rm /etc/aliases)
}}}
-* sane locales:
+* on draghi, add the host to the ldap using ud-host. Set the ssh key and the IP Address attributes.
- make sure there is _no_ locale defined in /etc/environment and /etc/default/locale
-
-* make debconf the same on every host: - dialog, - high
-{{{
- dpkg-reconfigure debconf
-}}}
-
-* add db.d.o to sources.list:
-{{{
- cat > /etc/apt/sources.list.d/debian.org.list << EOF
-deb http://db.debian.org/debian-admin lenny main
-deb-src http://db.debian.org/debian-admin lenny main
