[IDD #ZEM-237169]: Starting LDM Feed

Hi Shengting,

The fact that your 'notifyme' invocation does not connect
to idd.unidata.ucar.edu, but your 'telnet idd.unidata.ucar.edu 388'
does and then the connection is broken, is puzzling:

$ telnet idd.unidata.ucar.edu 388
Trying 128.117.140.3...
Connected to idd.unidata.ucar.edu.     <- the telnet invocation connects
Escape character is '^]'.
Connection closed by foreign host.     <- something is closing the connection

It is as if something is interrupting the port 388 connection to
idd.unidata.ucar.edu.  To my knowledge, nothing on our end should
be terminating the connection.  Also, I verified that no LDM on
the real server backends of the idd.unidata.ucar.edu cluster
received the connection attempt(s) by your 'notifyme' invocation(s).

We will need to consult our system administrator to see if he
can figure out what may be happening

Cheers,

Tom
