Russ, Our LDM didn't log this connection attempt -- not even to say that your LDM wasn't allowed. I suspect, therefore, that your LDM was unable to establish a TCP connection to ours. What is the output of the following command executed by the LDM user on Geoprod4: telnet uni14.unidata.ucar.edu 388 Regards, Steve Emmerson Ticket Details =================== Ticket ID: VVJ-331218 Department: Support LDM Priority: Normal Status: Closed
