1 == setup/integrate a new machine ==
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
13 echo 'Acquire::PDiffs "false";' > /etc/apt/apt.conf.d/local-pdiff
14 echo 'APT::Install-Recommends 0;' > /etc/apt/apt.conf.d/local-recommends
17 * sane locales: (make sure there is _no_ locale defined in /etc/environment and /etc/default/locale)
19 echo -n > /etc/environment
20 echo -n > /etc/default/locale
23 * make debconf the same on every host: - dialog, - high
25 apt-get install dialog &&
26 echo "debconf debconf/priority select high" | debconf-set-selections &&
27 echo "debconf debconf/frontend select Dialog" | debconf-set-selections
30 * unless we want to keep it:
32 dpkg -l postfix | grep '^ii postfix' && (dpkg --purge postfix && rm /etc/aliases)
35 * setup [[puppet|howto/puppet-setup]] (run the puppet client two or three times until things converge.)
37 * on draghi, add the host to /home/sshdist/.ssh/authorized_keys and generate.conf
38 (you want the host's rsa host key there: {{{cat /etc/ssh/ssh_host_rsa_key.pub}}})
40 : :: draghi :: && sudo vi /home/sshdist/.ssh/authorized_keys
41 : :: draghi :: && sudo vi /etc/userdir-ldap/generate.conf
43 * run generate, or wait until cron runs it for you
45 : :: draghi :: && sudo -u sshdist ud-generate
48 * fix nsswitch for ud fu. (you might have to restart sshd here)
50 sed -i -e 's/^passwd:\[[:space:]]\+compat$/passwd: compat db/;
51 s/^group:\[[:space:]]\+compat$/group: db compat/;
52 s/^shadow:\[[:space:]]\+compat$/shadow: compat db/' \
54 (cd / && env -i /etc/init.d/ssh restart)
57 * install userdir-ldap
59 apt-get update && apt-get install userdir-ldap
62 * on the host, run ud-replicate

73 * install debian.org which brings you shells and much other fun
75 apt-get install debian.org debian.org-recommended
78 * in /etc/ssh/sshd_config:
79 ** disable the DSA hostkey, so that it only does RSA
80 ** remove old host keys:
81 ** disable X11 forwarding
82 ** Tell it to use alternate authorized_keys locations
83 ** maybe link root's auth key there:
85 #| HostKey /etc/ssh/ssh_host_rsa_key
87 #| AuthorizedKeysFile /etc/ssh/userkeys/%u
88 #| AuthorizedKeysFile2 /var/lib/misc/userkeys/%u
90 cd /etc/ssh/ && rm -f ssh_host_dsa_key ssh_host_dsa_key.pub ssh_host_key ssh_host_key.pub &&
91 mkdir -p /etc/ssh/userkeys && ln -s /root/.ssh/authorized_keys /etc/ssh/userkeys/root &&
92 sed -i -e 's/^HostKey.*_dsa_key/# &/;
93 s/^X11Forwarding yes/X11Forwarding no/;
94 $ a AuthorizedKeysFile /etc/ssh/userkeys/%u
95 $ a AuthorizedKeysFile2 /var/lib/misc/userkeys/%u' sshd_config &&
96 (cd / && env -i /etc/init.d/ssh restart)
99 * try to login using your user and ssh key. you should get a homedir.
101 * try to become root using sudo.
103 * disable password auth with ssh (again: once you verified you can log in and become root using keys.)
105 #vi /etc/ssh/sshd_config
106 # | PasswordAuthentication no
108 sed -i -e 's/^PasswordAuthentication yes/PasswordAuthentication no/' /etc/ssh/sshd_config &&
109 (cd / && env -i /etc/init.d/ssh restart)
112 * make ca-certificates sane: (choose to *not* trust new certs, and we only want the spi cert activated)
114 echo "ca-certificates ca-certificates/trust_new_crts select no" | debconf-set-selections
115 sed -i -e 's/^[^#!].*/!&/; s#^!spi-inc.org/spi-cacert-2008.crt#spi-inc.org/spi-cacert-2008.crt#' /etc/ca-certificates.conf
116 dpkg-reconfigure ca-certificates
119 * Add debian-admin@debian.org to root in /etc/aliases
121 if ! egrep '^root:' /etc/aliases > /dev/null; then
122 echo "root: debian-admin@debian.org" >> /etc/aliases
123 elif ! egrep '^root:.*debian-admin@debian.org' /etc/aliases > /dev/null; then
124 sed -i -e 's/^root: .*/&, debian-admin@debian.org/' /etc/aliases
129 * sane default editor
131 apt-get install vim && update-alternatives --set editor /usr/bin/vim.basic
134 * add to munin on spohr
136 : :: spohr :: && sudo vi /etc/munin/munin.conf
139 * if it is a HP Proliant, or has other management fu, read [[howto/ilo-https]]
141 * edit dedication into in $DSA-PUPPET/modules/debian-org/misc/local.yaml
145 * add host to ldap: ud-host -a $USER -h ....
