[aprssig] IRLP APRS Status Script: Multiconnect Bug?

Recently Ken, G7VJA, of T2 ENGLAND had discovered that some
of the IRLP nodes are connected to several Tier 2 servers at the same
time.

Looking at the code of the IRLP APRS script ( last version 4.0 )  reveals
that it is using netcat to send the APRS object to the APRS-IS. The
default DNS address is rotate.aprs2.net.

Netcat seems to establish a new connection to rotate.aprs2.net without
disconnecting the previous connections. After a day or so the IRLP
APRS script maintains a tcp connection with all Tier 2 servers in the
rotate list. All but the most recent connection are useless and hanging.
They waste resources of the systems at both ends.

Just as an example. At present K7FED‑15 is connected with 22 (yes,
twenty-two) servers at the same time.

If you are using the script, please do not use rotate.aprs2.net as the server
in the config file aprs_status.conf. Use just one server of your choice from
the list of the 48 T2 servers ( http://www.aprs2.net/ ).
