[K12OSN] tftp problem on client after IP change on server

[rmcdaniel at indata.us]

Well, TFTP isn't running.  Hmmm, could be the problem.  Why doesn't TFTP
get setup to start automatically???  If TFTP isn't in my list of
services, how do I configure the box to start it automatically??  
Sorry for the trivial questions.


Thanks,

Ron
