yyamasaki, > As requested, the 3 computerś IP with ldm are: > > atm77.fis.ua.pt : 193.137.81.77 > atm78.fis.ua.pt : 193.137.81.78 > pp42.fis.ua.pt : 93.137.81.42 Should 93.137.81.42 be 193.137.81.42, instead? An LDM on 193.137.81.78 will not be able to connect to idd.cise-nsf.gov or idd.unidata.ucar.edu because a reverse-name lookup on that IP address fails.
