[App_rpt-users] New ACID release - BeagleBoard MAC Address

[Jim Duuuude]

This "somewhat misfeature" of Pickle (or at least the Ubuntu distro) was
never intended. However when it was first pointed out to me a realized
how much of an incredible blessing in disguise it was.

The reason being is: Threre is NEVER, EVER, EVER, *ANY* reason 
why ANYONE should trust a "toy" router to even accurately keep track of
much less observe static DHCP bindings. That is *JUST NOT* an acceptable
way of assigning a "static" LAN IP address.

Routers that allegedly support this "feature" (boy that's being nice) generally
don't very well and/or stably. I have had NOTHING BUT HEADACHES over
the year when people attempt to do this. PLEASE, DONT LET IT HAPPEN
TO YOU.

Just assign a *REAL*static LAN IP on the Pickle system. Use the netsetup
script if you arent comfortable with editing files in the Ubuntu distro. Assign
a LAN IP address that is outside the range that the router assigns DHCP
addresses. Sometimes, in rare cases, some routers will, by default
use the entire LAN range for assigning DHCP address. If so you
will need to configure the router to change this behavior, and "create"
a range of LAN addresses outside the routers range of DHCP addresses.

Believe me, this small amount of extra work when setting up a system
TOTALLY is worthwhile and WILL save you some major grief in the future.
