== setup/integrate 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
{{{
    apt-get install --no-install-recommends ssh
}}}

* sane editor
{{{
    apt-get install --no-install-recommends vim
}}}

* 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 --no-install-recommends dialog &&
    echo "debconf debconf/priority        select high" | debconf-set-selections &&
    echo "debconf debconf/frontend        select Dialog" | debconf-set-selections
}}}

* unless we want to keep it:
{{{
    dpkg -l postfix | grep '^ii  postfix' && (dpkg --purge postfix && rm /etc/aliases)
}}}

* on draghi, add the host to the ldap using ud-host.  Set the ssh key and the IP Address attributes.

* run generate, or wait until cron runs it for you.  Update DNS.
{{{
    : :: draghi :: && sudo -u sshdist ud-generate && sudo -H ud-replicate && sudo -H puppetd -t
    : :: orff :: && sudo -H ud-replicate
}}}

* setup [[puppet|howto/puppet-setup]]  (run the puppet client two or three times until things converge.)


* fix nsswitch for ud fu.  (you might have to restart sshd here)
{{{
    sed -i -e 's/^passwd:\[[:space:]]\+compat$/passwd:         compat db/;
              s/^group:\[[:space:]]\+compat$/group:          db compat/;
              s/^shadow:\[[:space:]]\+compat$/shadow:         compat db/' \
        /etc/nsswitch.conf
    (cd / && env -i /etc/init.d/ssh restart)
}}}

* on the host, run ud-replicate
{{{
    echo draghi.debian.org,draghi,db.debian.org,db,82.195.75.106,::ffff:82.195.75.106 ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAy1mAS0xIOZH9OrJZf1Wv9qYORv5Z5fmpF0o8Y4IMdS+ZzTjN1Sl8M77jaFTJbumJNs+n2CMcX8CoMemQEPBoRe20a5t3dExPQ3c7FNU0z+WIVFbu/oTTkAWGp5gCDwF3pg2QxUjqYc0X4jpv6pkisyvisij6V/VJ5G1hsIMuKqrCKYyyyiJJytfzSfRrBx2QvB5ZWQxhYeSYDoLDvuF31qUy4TLZ/HR3qZQ1cBrP9dCh5d+GQxdY9LuO6zjlnSyU64GHkyjYt3p03AKG4plD7WHX01bD0DQQ/NOFVwFhOZ63mePyridPuqBMFW39jBf4jSsewV95RE5VbY04+MY4XQ== root@draghi >> /etc/ssh/ssh_known_hosts &&
    ud-replicate
}}}

* check if it worked:
{{{
    id weasel
}}}

* install debian.org which brings you shells and much other fun
{{{
    apt-get install debian.org debian.org-recommended
}}}

* On handel, make sure the certs exist for the new host
{{{
  : :: handel :: : && sudo -u puppet make -C /srv/puppet.debian.org/ca/ install
}}}

* run puppet a couple times
{{{
    puppet agent -t; puppet agent -t; puppet agent -t; puppet agent -t
}}}

* try to login using your user and ssh key.  you should get a homedir.

* try to become root using sudo.

* make ca-certificates sane:  (choose to *not* trust new certs, and we only want the spi cert activated)
{{{
    echo "ca-certificates ca-certificates/trust_new_crts  select no" | debconf-set-selections
    sed -i -e 's/^[^#!].*/!&/; s#^!spi-inc.org/spi-cacert-2008.crt#spi-inc.org/spi-cacert-2008.crt#' /etc/ca-certificates.conf
    dpkg-reconfigure ca-certificates
}}}

* Add debian-admin@debian.org to root in /etc/aliases
{{{
  if ! egrep '^root:' /etc/aliases > /dev/null; then
    echo "root: debian-admin@debian.org" >> /etc/aliases
  elif ! egrep '^root:.*debian-admin@debian.org' /etc/aliases > /dev/null; then
    sed -i -e 's/^root: .*/&, debian-admin@debian.org/' /etc/aliases
  fi
  newaliases
}}}

* install samhain and get puppet to configure it
{{{
  apt-get install samhain
  puppet agent -t
}}}

* if it is a HP Proliant, or has other management fu, read [[howto/ilo-https]]

* edit dedication into in $DSA-PUPPET/modules/debian-org/misc/local.yaml

* Add host to smarthost machines in $DSA-PUPPET/modules/debian-org/misc/local.yaml (if so desired).  Set MX in ud-ldap.

* add to nagios
