Hi Yoshihiro,
I apologize for not being able to get back to you sooner on your problem
(we are holding training workshops at the moment).
re:
> Yes, the ldm is running on the atm77.fis.ua.pt but I am
> not receiving any data at all.
I just checked and see that atm77.fis.ua.pt is contacting idd.cise-nsf.gov
to request CONDUIT data:

Even though it looks like the data should flow to atm77, it is not.
Interesting observations:
1) An 'ldmping' to from idd.cise-nsf.gov to atm77 does not work:

It appears that something changed either in a firewall somewhere or some
network routing
configuration.
> Is there any way to check all my conection with ldm ??
> best regards,
In addition to the checks above, I tried using 'rpcinfo' to interrogate your
machine:
/usr/sbin/rpcinfo -p atm77.fis.ua.pt
This got no response.
Questions:
- what is the operating systme on atm77 (please return results of 'uname -a')
- was the operating system on atm77 upgraded recently
- do you have an 'allow' line in your ~ldm/etc/ldmd.conf file for all machines
from the unidata.ucar.edu domain? It should look like:
# ALLOW anything to your own machine and all Unidata machines
allow ANY
^((localhost|loopback)|(127\.0\.0\.1\.?$)|([a-z].*\.unidata\.ucar\.edu\.?$)
- when you did your LDM installation, did you remember to change the mode/owner
of
~ldm/bin/rpc.ldmd and ~ldm/bin/hupsyslog using the command:
<as 'ldm'>
cd ~ldm
cd ldm-6.4.6.4/src
make distclean
./configure
make
make install
sudo make install_setuids <- the line I am referring to
cd ~
rm runtime
ln -s ldm-6.4.6.4 runtime
I am working with our system administrator to try and figure out why data
products
are not flowing to you even though both idd.unidata.ucar.edu and
idd.cise-nsf.gov
are receiving AND honoring feed requests.
Cheers,
Tom
