I was getting ready to contact you about trying some data feed experiments that I would like to run. >It took some time but today I finaly got back to installing LDM. Execllent. What version did you install? I ask because I put together a 5.2.2 release the day before yesterday for people building from source code to grab. >My systema manager pulled down the firewall for a some minutes and we tried >connecting to atm.geo.nsf.gov and had the following answer: > >trixie% ldmping -i 2 atm.geo.nsf.gov >Nov 15 13:44:06 State Elapsed Port Remote_Host rpc_stat >Nov 15 13:44:06 ADDRESSED 0.339920 0 atm.geo.nsf.gov RPC: Unable to >receive; errno = Connection reset by peer >Nov 15 13:44:23 NAMED 15.000104 0 atm.geo.nsf.gov can't contact >portmapper: RPC: Timed out >Nov 15 13:44:26 ADDRESSED 0.342186 0 atm.geo.nsf.gov RPC: Unable to >receive; errno = Connection reset by peer > >Any idea? I logged onto atm.geo.nsf.gov right after I saw this and saw the connection attempt from trixie.at.fcen.uba.ar. I then looked up the allows in atm's ~ldm/etc/ldmd.conf file and found that I had a typo in the line that allows connections from UBA. I have fixed the problem, and am restarting the LDM on atm even as I write this message. You should be able to connect to atm now. I want to bring you up to date on what has happened in the past two months. The University of Rio de Janerio has agreed to act as a top level IDD redistribution node for Brazil. I am hoping that they will also be willing to feed UBA and potentially other universities in Argentina and even Paraguay. At the same time, based on exerience we gained by working with the University of Para in Belem, we have been making major modifications to the LDM so that it will be better able to distribute data to remote sites (sites that are electronically far away from feed sites). A test version of this LDM release should be ready by the end of today or sometime on Monday. This is why your email is so timely! Until I can get you the new LDM, I would like you to once again try connecting to atm.geo.nsf.gov from trixie. Also, instead of your system administrator bringing down the entire firewall, it would be better if s/he simply allowed bidirectional access for port 388. This way we could run tests at will. >Thanks Cheers, Tom
