[arm-allstar] Address to use SuperMon away from home network

Simon,

   Enquiries to asnode sends you to the IP address of a given node number
it does not actually connect you to a specific port unless specified. The
point is since node numbers are just sequential numbers a hacker or anyone
could write a script to probe every Allstar IP address and its ports. Here
is an example -

 http://41245.asnode.org:8181/allmon/about.php

I pulled this info from google so its no secret. This individual has put
their allmon out there for anyone to see, Since the CURRENT allmon is very
insecure a hacker could get into this system very easily. There are
hundreds out there like this.

So lets say your node was 40000 -

http://40000.asnode.org:80/     << the 0 is default and not needed but you
could put any port there.

would in fact connect a user to your default Allstar web page if it was
port forwarded and you would see this -

THIS IS A TEST !

If you see this the web server is working.

Likewise if you used ssh or putty, etc.   -   ssh 40000.asnode.org -p 222
- you would be connected to this node ssh port assuming it was on port 222.
