First of all, thanks for directing me to think about this repair,
instead of giving instruction to be followed blindly, it's the only
way I'll really learn anything.
Secondly, I'm wondering, after digesting the wiki, if I haven't misled
everyone by not relating the whole story.
This set-up used to start and connect without any problem, until I ran
an inappropriate command effectively starting the backend a second
time. (you may recall this Bill)
What seems to be a functional hack at this point is adding a stop and
start BE command separated by a sleep 5 in the mythfrontend file.
The wiki may be the correct fix, however, bit it leaves me wondering
why did it work before and not now.
