Also, change the way uptime is captured. The mpd console is no longer used to
get PPP uptime data, which will prevent spamming of PPP logs with console access messages.
This means we no longer have to write out mpd_<interface>.query files to /var/etc.
Now, a simple calculation of the age of the /tmp/<interface>up file is used. This
gives the same data within the second as the console data so it seems acceptable.
I removed some "rm -f" calls from ppp-linkdown as there was already code in interfaces.inc
interface_bring_down function that unlinks the <interface>up and <interface>_router files.
There is still the rm -r nameserver_<interface> call in the linkdown script. Maybe this should
be moved to the interfac_bring_down function for consistency? Also, I commented out the
ngctl shutdown <interface>: call. I think it's probably not necessary any more.
Moved three "unlink_if_exists" calls to happen after calling kill_by_pid for mpd processes.
The unlinked files are useful during the process of brining down the mpd interfaces
for calculating the link uptime in the "linkdown" script.
The interface configure function is called after "write_config()" because
we must write the new data to the config before reading the config to
bring up the interface with the new settings.
The "local" search domain signifies to local hosts that are running
mDNS (bonjour or avahi) that mDNS is to be used to look up local hosts
instead of doing a normal DNS query to the server listed in
/etc/resolv.conf on the local host.
Also, hosts running bonjour or avahi can not ping or reach *any* other
host by name if it is not running some mDNS implementation.
Essentially, if DHCP tells the local host that it's search domain is
"local" then hosts running mDNS will not query the pfsense DNS server
for any local lan DNS lookups.
