Bandwidth monitoring interface for default storage node is incorrectly set by installer.

[Wayne Workman]

svn 4405 cloud 5469 Fedora 23 Server minimal

The installer correctly identified my external interface name in Fedora 23 server, when it asks for confirmation on the interface name. It’s ens3 in this case. But, the default storage node created with a fresh installation sets the interface for this node as eth0, which obviously breaks the bandwidth monitor.

I’ve done a little digging, trying to figure out where the initial configuration is happening, and I’ve found two files (in the installation files) that have different settings set in them.

inside of /svn/trunk/packages/web/lib/fog/Config.class.php

Line 48:

define( "MULTICASTINTERFACE", "eth0" );

lines 100 and 101:

define('NFS_ETH_MONITOR', 'eth0');
define('UDPCAST_INTERFACE', 'eth0');

However, inside of svn/trunk/lib/common/functions.sh, it looks like the interface is being set, but it’s not working?

I don’t think it was incorrectly set by installer, but rather, it was incorrect (defaulting to eth0) from a long time ago. Probably before I started reading the name of the interface.
