+= how to add a new machine =
Note: this has recently been changed to rely more on [[puppet|howto/puppet-setup]]. If stuff breaks fix it.
-* install ssh if it isn't there already
+* some initial stuff:
{{{
- apt-get install ssh
-}}}
-
-* make apt sane
-{{{
- echo 'Acquire::PDiffs "false";' > /etc/apt/apt.conf.d/local-pdiff
- echo 'APT::Install-Recommends 0;' > /etc/apt/apt.conf.d/local-recommends
-}}}
-
-* sane locales: (make sure there is _no_ locale defined in /etc/environment and /etc/default/locale)
-{{{
- echo -n > /etc/environment
- echo -n > /etc/default/locale
-}}}
-
-* make debconf the same on every host: - dialog, - high
-{{{
- apt-get install dialog &&
+ apt-get install --no-install-recommends ssh vim &&
+ echo -n > /etc/environment &&
+ echo -n > /etc/default/locale &&

echo "debconf debconf/frontend select Dialog" | debconf-set-selections
}}}
dpkg -l postfix | grep '^ii postfix' && (dpkg --purge postfix && rm /etc/aliases)
}}}
-* setup [[puppet|howto/puppet-setup]] (run the puppet client two or three times until things converge.)
-
-* on draghi, add the host to /home/sshdist/.ssh/authorized_keys and generate.conf
-(you want the host's rsa host key there: {{{cat /etc/ssh/ssh_host_rsa_key.pub}}})
-{{{
- : :: draghi :: && sudo vi /home/sshdist/.ssh/authorized_keys
- : :: draghi :: && sudo vi /etc/userdir-ldap/generate.conf
-}}}
-* run generate, or wait until cron runs it for you
-{{{
- : :: draghi :: && sudo -u sshdist ud-generate
-}}}
+* on draghi, add the host to the ldap using ud-host. Set the ssh key and the IP Address attributes.
-* fix nsswitch for ud fu. (you might have to restart sshd here)
+* run generate, or wait until cron runs it for you. Update DNS.
