Change FOG Server IP Address

If we need to transfer the server from one network to another or provide another interface on the fog server or to provide another static IP as per the requirement, then we can change the FOG server IP.

Main Steps:-

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

• Rerun the installer

• 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

FOG Settings File

Update the /opt/fog/. file:

sudo vim /opt/fog/.fogsettings

Instructions on using Vim: Vim

There are several settings in here that may need updated depending on if you're running DHCP on the fog server or not. But the one that must be updated is the ipaddress=x.x.x.x setting. Update this with the correct IP. Save your changes and quit, and then re-run the fog installer.

Additional information about the /opt/fog/.fogsettings file can be found here: .fogsettings

DHCP server configuration file (/etc/dhcpd.conf) restart service after changes are made.

PXE Menu changes ( //pxelinux.cfg/default)

Replace any previous IP addresses with new IP address

This also applies if your DNS server has changed. You would replace all previous DNS IP addresses with new DNS server IP address.

Example (no change to DNS):

Old line in /tftpboot/pxelinux.cfg/default:

append initrd=fog/images/init.gz root=/dev/ram0 rw ramdisk_size=127000 ip=dhcp dns=X.X.X.1 mode=quickimage keymap=web=X.X.X.X/fog/ loglevel=4 consoleblank=0

New line in /tftpboot/pxelinux.cfg/default:

append initrd=fog/images/init.gz root=/dev/ram0 rw ramdisk_size=127000 ip=dhcp dns=192.168.1.1 mode=quickimage keymap= web=X.X.X.X/fog/ loglevel=4 consoleblank=0
