Dean, I tried to reproduce this problem, but cannot. I am able to access the metar data without any problems. You may have Internet connectivity problem at your local institution. There are several ports you need open at your institution in order to run the IDV so that it may connect to different data servers. In general, ports 112, 8080 and 80 are required. This is especially true for the metar data accessed from ADDE. You must have access to port 112. http://www.unidata.ucar.edu/software/idv/docs/userguide/Systems.html Best, Unidata IDV Support > Full Name: Dean Steinmetz > Email Address: address@hidden > Organization: None > Package Version: 5.2 build date:2015-08-26 18:19 UTC > Operating System: Linux > Hardware: Java: home: /usr/local/IDV_5.2/jre version: 1.8.0_45 > j3d:1.6.0-pre9-daily-experimental daily > Description of problem: Error connecting to: adde.ucar.edu > Connection refused > > This has happened more than once.
