In order to fully test the data capabilities of the D-STAR units, we needed to build a network around it to test. Below is our network:
Some of the Particulars:
RedHat Server: Served as the DNS server for the entire network, and ran IPTABLES as a firewall. The server was connected to a Road Runner connection that was up 24 x 7. The server was running web, ftp, email, Novell Netware, Samba (Windows), and Appletalk (netatalk) services.
Switches: We had to use network switches instead of hubs. Why? Basic networking theory: a switch will only pass required traffic along the network, whereas a hub passes all traffic to all nodes. If we had hubs, if the Mac and PC wanted to talk to each other on the same side of the network (not needing the D-STAR), then the D-STARS would have transmitted non-essential data. In order to limit D-STAR transmissions, use switches in strategic locations.
Computer Selection: The protocol of choice was IP, allowing Macintosh, Windows, and Linux to all interact with each other. Because the Linux Server also operates as a Netware server (mars-nwe), a Windows server (samba), and a Macintosh server (netatalk), we were able to test each computer with native protocols. All connections worked impressively.
