[PLUG] Linux on AT&T Cable Modem

[Sean Whitney]

It should work out of the box with linux, mine does, just make sure you use 
dhcpcd and not pump.  Pump doesn't have all the bells and whistles of pump 
and seems to perform better.  

Note: I don't advise getting a DHCP address and then assigning that to 
yourself as static.  Although this will work perfectly fine with normal dhcp 
servers.  Cisco ubr routers have a option called cable source verify that 
will lock your modem out unless it has optained a proper dhcp lease.

This is an especially good time for you vacationers who plan to fly, because
the Reagan administration, as part of the same policy under which it
recently sold Yellowstone National Park to Wayne Newton, has "deregulated"
the airline industry.  What this means for you, the consumer, is that the
airlines are no longer required to follow any rules whatsoever.  They can
show snuff movies.  They can charge for oxygen.  They can hire pilots right
out of Vending Machine Refill Person School.  They can conserve fuel by
ejecting husky passengers over water.  They can ram competing planes in
mid-air.  These innovations have resulted in tremendous cost savings which
have been passed along to you, the consumer, in the form of flights with
amazingly low fares, such as $29.  Of course, certain restrictions do apply,
the main one being that all these flights take you to Newark, and you must
pay thousands of dollars if you want to fly back out.
