====== Necessary Changes After Cloning A System ======

  - Change the hostname in the files ''/etc/hostname'', ''/etc/mailname'' and ''/etc/hosts''. Afterwards run the script ''/etc/init.d/hostname.sh'' to set the new hostname on the running system:

<cli prompt='#'>
root@host:~# /etc/init.d/hostname.sh
</cli> <
  - Remove the SSH host keys which were generated on the old system:

<cli prompt='#'>
root@host:~# rm /etc/ssh/ssh_host_*key{,.pub}
</cli>

and create new SSH host keys for the new system:

<cli prompt='#'>
root@host:~# ssh-keygen -A
</cli> <
  - If a static IP address configuration is used, change the IP addresses in ''/etc/network/interfaces'' <
  - If postfix is installed change the hostname in the file ''/etc/postfix/main.cf'':

<file ini /etc/postfix/main.cf>
myhostname = <new hostname>
mydestination = <new hostname>, <new fqdn>, localhost.localdomain, localhost
</file>

Update the local aliases file:

<cli prompt='#'>
root@host:~# newaliases
</cli> <
  - Reboot the system. <
