Support for multiple nics / subnets

[Tom Elliott]

the interface for udp-sender is stored in /var/www/fog/lib/fog/Config.class.php under svc_setting method. I believe it’s defined value is:
MULTICASTINTERFACE

Hi, thanks. I tried this already, but tried it once again and the same result. Then I realized, that maybe it needs /etc/init.d/FOGMulticastManager restart and yes, now the interface is changed

Few questions however - what is that setting - FOG_UDPCAST_INTERFACE - in FOG Configuration for? And why are there 2 configuration places - database and config file? Is it for some legacy reasons, or?

[Tom Elliott]

I think UDPCAST_INTERFACE is the intentional item to be used for dynamics. I can take a look on the SVN side of the house and get the interface from there.

[Tom Elliott]

SVN 2004 now uses the FOG_UDPCAST_INTERFACE rather than the defined interface in Config.class.php.

So, if I upgrade to SVN 2004, it should no longer use config and there will by only database (via FOG Configuration web interface) as configuration storage?

And what’s “dynamics”?

Thanks.

[Tom Elliott]

Dynamics, I am only guessing here that it works in this way now that we’re pulling from db. You wouldn’t have to restart the FOGMulticastManager service to change which interface you’re attempting to use.

It seem to work - svn 2014 - creates udp-sender processes with right interface no matter what’s in /var/www/fog/lib/fog/Config.class.php. Didn’t test deploying.

OK, so here is what’s needed to switch FOG 1.2.0 between networks (interfaces):

• FOG System Settings -> FOG Configuration:
  * General Settings: FOG_WOL_HOST (change ip); FOG_WOL_INTERFACE (change iface)
  * Multicast Settings: FOG_UDPCAST_INTERFACE (change iface)
  * NFS Server: FOG_NFS_ETH_MONITOR (change iface)
  * TFTP Server: FOG_TFTP_HOST (change ip)
  * Web Server: FOG_WEB_HOST (change ip)
• Storage Management -> DefaultMember:
  * IP Address (change ip)
  * Interface: (no changes)
• /tftpboot/default.ipxe: change ip in last line
• change default gateway using ip command (to make wake on lan work - it uses default gw for broadcasts):
  * ip r del default - delete current
  * ip r add default via <gw for second network>
