From the faq <http://www.opendx.org/faq.html#cantconnect>
The user interface and the server (exec) communicate over sockets. Netwoking must work in order for this process to work completely. There are several reasons why this communictaion may fail. One may be that your hostname does not resolve properly. You can test this by using the ping, and hostname commands to determine if you can ping your own machine or you can try setting the DXHOST environment variable to "unix" to default to the local machine. A second reason may be that you have a firewall running on your system that refuses the socket communication over the IP ports that DX uses. Try shutting off your firewall to see if this fixes the problem.
Other tests to try: Does dx -execonly work? -- ............................................................................. David L. Thompson Visualization and Imagery Solutions, Inc. mailto:[EMAIL PROTECTED] 5515 Skyway Drive, Missoula, MT 59804 Phone : (406)756-7472
