[Xastir] Running wxnowsrv.pl

[Joseph LaFerla]

Hi Tom

No other messages, just what I mentioned.  

When I run the script on the machine which has the wx station, it all works.  I can do it that way, but it would be cleaner for me if I didn’t have to.

This is wrong.  The script is not set up to fetch the wxnow.txt file from 
another machine on the network, it's set to read a local file, and *provide*
its data to another machine on the network.  It knows nothing windows-style 
network share syntax like you're using.  I'm surprised you didn't get an
error about not being able to read the file.

You need to run the script on the machine where the wxnow file lives 
(192.168.1.20), and the path would be "/home/pi/CumulusMX/wxnow.txt".

When you do it this way, the pi with your weather station is running a simple
server daemon that your other pis on the network (e.g., the one with xastir)
can connect to to get weather data.  That daemon listens on port 5500 by 
default (unless you give an extra argument with the port number).

This suggests that the call that creates a new socket a few lines up from line
155 is failing.  $listen should be defined there, and so $listen->accept
should work.  If you're getting this, the problem is somewhere else.

It is wrong, but you clearly have some other issue, too, because the 
network port initialization seems not to have worked.  Are you getting any
other error messages from the program besides the one about the undefined
value.
