    8585
    86 === Syn Cookies ===
    87 
    88  * Enable syncookies:
    89 
    90 {{{
    91 echo 1 > /proc/sys/net/ipv4/tcp_syncookies
    92 }}}
    93 
    94  * Preserve syncookies on reboot:
    95 
    96 {{{
    97 echo 'net.ipv4.tcp_syncookies=1' >> /etc/sysctl.conf
    98 }}}
    99 
    100 === Install and configure mandatory packages ===
    101 
    102  * Login as root and install the following packages (if you plan to install postfix, replace esmtp-run with postfix)
    103 
    104 {{{
    105 # aptitude install ssh ntp less emacs21-nox cron-apt iproute mailx esmtp-run locales
    106 }}}
    107 
    108  * Configure locales to use en_US.UTF-8 (run dpkg-reconfigure locales if necessary)

    114 }}}
    115

    125 }}}
    126 
    127  * Configure ssh to only accept connections with auth keys (unless this is a server that should be accessible by members). Edit /etc/ssh/sshd_config and uncomment/change these lines:

    140 === Fix Bash ===
    141 
    142  * Overwrite /root/.bashrc with:

    146 export PS1='$? \h:\w\$ '
    147 umask 022
    148 
    149 # You may uncomment the following lines if you want `ls' to be colorized:
    150 # export LS_OPTIONS='--color=auto'
    151 # eval "`dircolors`"
    152 # alias ls='ls $LS_OPTIONS'
    153 # alias ll='ls $LS_OPTIONS -l'
    154 # alias l='ls $LS_OPTIONS -lA'
    155 #
    156 # Some more alias to avoid making mistakes:
    157 alias rm='rm -i'
    158 alias cp='cp -i'
    159 alias mv='mv -i
    160 }}}
    161 
    162  * Modify the following lines in /etc/skel/.bashrc
    163 {{{

    171 {{{
    172 mkdir /etc/skel/.ssh
    173 touch /etc/skel/.ssh/authorized_keys
    174 }}}
    175 
    176 === Serial console login (not for DomU's!) ===
    177 
    178 If you did not use the serial console installer, then perform the following:
    179 
    180  * Edit the /etc/inittab file. Uncomment and modify:
    181 
    182 {{{
    183 T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100
    184 }}}
    185 
    186  * Refresh:
    187 
    188 {{{
    189 $ sudo init q
    190 }}}

    196 terminal --timeout=10 serial console
    197 }}}
    198 
    199  * Add the following lines to the Start Default Options. You should already have a line such as:
    200 
    201 {{{
    202 # kopt=root=/dev/mapper/vg_servername0-root ro
    203 }}}
    204 
    205  add to it, so that your final line says:
    206 
    207 {{{
    208 # kopt=root=/dev/mapper/vg_servername0-root ro console=ttyS0,115200n8
    209 }}}
    210 
    211  Refresh grub's config file:
    212 
    213 {{{
    214 # update-grub
    215 }}}
    216
