IP fisso in partizione recupero OS X

This small hint may be of some help when you have to reinstall OS X from a recovery partition in a network environment that does not have an active DHCP server. In this case, a small intervention in the Terminal is required.

Once you’ve booted into the Recovery partition, open Terminal by clicking its icon in the Utilities menu. Then:

  • Get a list of the network interfaces for the Mac you are installing Lion on:

networksetup -listallnetworkservices

  • Set up the network interface, as listed by the output of the command mentioned above (Ethernet or otherwise):

networksetup -setmanual {INTERFACE NAME} {IP ADDRESS} {SUBNET MASK} {ROUTER}

  • Set the name (DNS) servers:

networksetup -setdnsservers {INTERFACE NAME} {YOUR DNS SERVER}

  • Verify that the changes have been correctly saved:

ifconfig

  • Examine all the entries and find the one you have actually worked on (ex. en0 is generally, but not always Ethernet).
  • Quit Terminal and continue with your installation by following the onscreen steps.
  • Wait for the download to finish
  • Enjoy
