3 Note: this has recently been changed to rely more on [[puppet|howto/puppet-setup]]. If stuff breaks fix it.
6 * install ssh if it isn't there already
16 * sane locales: (make sure there is _no_ locale defined in /etc/environment and /etc/default/locale)
18 echo -n > /etc/environment
19 echo -n > /etc/default/locale
22 * make debconf the same on every host: - dialog, - high
24 apt-get install dialog &&
25 echo "debconf debconf/priority select high" | debconf-set-selections &&
26 echo "debconf debconf/frontend select Dialog" | debconf-set-selections
29 * unless we want to keep it:
31 dpkg -l postfix | grep '^ii postfix' && (dpkg --purge postfix && rm /etc/aliases)
34 * on draghi, add the host to the ldap using ud-host. Set the ssh key and the IP Address attributes.
36 * run generate, or wait until cron runs it for you
38 : :: draghi :: && sudo -u sshdist ud-generate && sudo -H ud-replicate
41 * setup [[puppet|howto/puppet-setup]] (run the puppet client two or three times until things converge.)
44 * fix nsswitch for ud fu. (you might have to restart sshd here)
46 sed -i -e 's/^passwd:\[[:space:]]\+compat$/passwd: compat db/;
47 s/^group:\[[:space:]]\+compat$/group: db compat/;
48 s/^shadow:\[[:space:]]\+compat$/shadow: compat db/' \
50 (cd / && env -i /etc/init.d/ssh restart)
53 * install userdir-ldap
55 apt-get update && apt-get install userdir-ldap
58 * on the host, run ud-replicate

69 * install debian.org which brings you shells and much other fun
71 apt-get install debian.org debian.org-recommended
74 * in /etc/ssh/sshd_config:
75 ** disable the DSA hostkey, so that it only does RSA
76 ** remove old host keys:
77 ** disable X11 forwarding
78 ** Tell it to use alternate authorized_keys locations
79 ** maybe link root's auth key there:
81 #| HostKey /etc/ssh/ssh_host_rsa_key
83 #| AuthorizedKeysFile /etc/ssh/userkeys/%u
84 #| AuthorizedKeysFile2 /var/lib/misc/userkeys/%u
86 cd /etc/ssh/ && rm -f ssh_host_dsa_key ssh_host_dsa_key.pub ssh_host_key ssh_host_key.pub &&
87 mkdir -p /etc/ssh/userkeys && ln -s /root/.ssh/authorized_keys /etc/ssh/userkeys/root &&

91 $ a AuthorizedKeysFile2 /var/lib/misc/userkeys/%u' sshd_config &&
92 (cd / && env -i /etc/init.d/ssh restart)
95 * try to login using your user and ssh key. you should get a homedir.
97 * try to become root using sudo.
99 * disable password auth with ssh (again: once you verified you can log in and become root using keys.)
101 #vi /etc/ssh/sshd_config
102 # | PasswordAuthentication no
104 sed -i -e 's/^PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config &&
105 (cd / && env -i /etc/init.d/ssh restart)
108 * make ca-certificates sane: (choose to *not* trust new certs, and we only want the spi cert activated)
110 echo "ca-certificates ca-certificates/trust_new_crts select no" | debconf-set-selections
111 sed -i -e 's/^[^#!].*/!&/; s#^!spi-inc.org/spi-cacert-2008.crt#spi-inc.org/spi-cacert-2008.crt#' /etc/ca-certificates.conf
112 dpkg-reconfigure ca-certificates
115 * Add debian-admin@debian.org to root in /etc/aliases
117 if ! egrep '^root:' /etc/aliases > /dev/null; then
118 echo "root: debian-admin@debian.org" >> /etc/aliases
119 elif ! egrep '^root:.*debian-admin@debian.org' /etc/aliases > /dev/null; then
120 sed -i -e 's/^root: .*/&, debian-admin@debian.org/' /etc/aliases
125 * add to munin on spohr
127 : :: spohr :: && sudo vi /etc/munin/munin.conf
130 * if it is a HP Proliant, or has other management fu, read [[howto/ilo-https]]
132 * edit dedication into in $DSA-PUPPET/modules/debian-org/misc/local.yaml
