Change FOG Server IP Address

Procedural Steps

  • Follow appropriate steps for your Linux distribution to change the OS’s IP address.

  • Update the ipaddress= field (and other fields if necessary) inside the /opt/fog/.fogsettings file. More information about the fogsettings file.

  • Rerun the installer, you’ll need to use –recreate-CA and –recreate-keys keys as the installer provides a certificate with a Common Name based on the ip which will be shipped in the iPxe kernel and failed to load any https resources as the certificate isn’t valid anymore.

  • Update the IP address inside /tftpboot/default.ipxe (look for the chain line i.e chain https://x.x.x.x/fog/service/ipxe/boot.php##params)

  • Update the IP address for the storage node on the FOG system where you changed the IP address Web Interface -> Storage Management

  • Update the IP address on a any master storage node that may reference this FOG server Web Interface -> Storage Management

  • (For master server) Update the FOG_WEB_HOST value Web Interface -> FOG Configuration -> FOG Settings -> Web Server -> FOG_WEB_HOST

  • (For master server) Update the FOG_TFTP_HOST value Web Interface -> FOG Configuration -> FOG Settings -> TFTP Server -> FOG_TFTP_HOST

Optionaly if you have configured a dhcpd:

  • Update IP addresses (fog and gateway) inside the /etc/dhcp/dhcpd.conf.

  • Don’t forgot to check your /etc/export for nfs server as well as your apache2 configuration as the installer override it.
