Actually, this does not look OK.  A successful 'ldmping' would look like:

ldmping idd.unidata.ucar.edu
Oct 07 15:16:07 INFO:      State    Elapsed Port   Remote_Host

Oct 07 15:16:07 INFO: RESPONDING   0.006607  388   idd.unidata.ucar.edu  

Your test did not get the RESPONDING message.

It is likely being caused by lack of reverse DNS (IP -> name).

Your new IP address does not resolve into any name:

% nslookup 130.206.30.83
Server:         128.117.140.56
Address:        128.117.140.56#53

** server can't find 83.30.206.130.in-addr.arpa.: NXDOMAIN

Without reverse DNS your feed REQUEST(s) will be denied.

Forward DNS, on the other hand, is correctly setup:

nslookup eady.uib.es
Server:         128.117.140.56
Address:        128.117.140.56#53

Non-authoritative answer:
Name:   eady.uib.es
Address: 130.206.30.83

The solution for the problem is to get your networking folks to
setup reverse DNS for your LDM machine.

re:
> Thanks,

No worries.

Cheers,

Tom
