Hi Hongming,

This is not enough information for me to say whether the error was
significant or not.  However, from the information gathered below, I
suspect that is not the problem.

It looks like for some reason access is blocked to your ldm port, 388. 
Here are a few diagnostics I ran:

        (anne) imogene:/home/anne/ldm/notes 149 % ping gp7.wwb.noaa.gov
        PING gp7.wwb.noaa.gov (140.90.195.39) from 128.117.140.28 : 56(84)

        --- gp7.wwb.noaa.gov ping statistics ---

        round-trip min/avg/max/mdev = 52.255/67.604/92.294/16.307 ms

So, ping tells me your machine is up.

        (anne) imogene:/home/anne/ldm/notes 150 % rpcinfo -p gp7.wwb.noaa.gov
        No remote programs registered.

rpcinfo tells me that for some reason I can't get information about your
ports.

        (anne) imogene:/home/anne/ldm/notes 151 % telnet gp7.wwb.noaa.gov 388
        Trying 140.90.195.39...
        Connected to gp7.wwb.noaa.gov.
        Escape character is '^]'.
        Connection closed by foreign host.

This telnet tells me that for some reason I'm not allowed to connect to
port 388, the ldm port.


        (anne) imogene:/home/anne/ldm/notes 152 % telnet gp7.wwb.noaa.gov 390
        Trying 140.90.195.39...
        telnet: connect to address 140.90.195.39: Connection refused

This telnet seems to tell me that there's nothing running on port 390. 
I tried this just for comparison with the telnet to port 388 above. 
With that telnet it appears that something is running but that the
connection was denied for some reason.

This leads me to suspect that something is not allowing connections to
port 388.  Do you have a firewall in place?  If so, is port 388 open? 
Is your portmapper running?  Is your /etc/hosts.allow correctly
configured?

I will be attending a meeting all day today, and thus won't be
responding to my email probably until tomorrow.  Please let me know what
you find out about this problem.
