Executive summary: hostname(1) isn't enough.

Core networking

  • Update /etc/hostname

  • Update /etc/hosts, so local address(es) resolves with the new system name.

  • Reload the network configuration. You have two options

      invoke-rc.d hostname.sh start
invoke-rc.d networking force-reload
invoke-rc.d network-manager force-reload
