Connecting to Your Network (LAN) 112 Getting Started Guide To just test your network, you can use the ping utility. With a known IP address on your network, from the main menu select Internet|Network utilities. Select the Ping tab, type the IP address (such as 192.66.100.5), and click on Go! After a moment, you should see messages that begin with “64 bytes from...” appearing on your screen. If instead you get a “Network is unreachable” message, your net- work is not configured properly to reach that IP address. If there is a long pause with no messages, the network might be working, but the computer you are try- ing to connect to may not be available. Click on Stop to stop pinging that IP address. If those tests fail, or if you don’t have an internal Web site that is convenient for testing, review the configuration information that follows to help establish a con- nection. Checking Your Ethernet Card Most LAN connections these days are established via an Ethernet card. Other types of connections include ATM and Token Ring, which Linux does support. Only Ethernet connections are described in this section. The easiest method of setting up your Ethernet card with the correct network address information is via the Coas administration interface. To start this utility, choose COAS|Network|Ethernet Interfaces on the KDE main menu. The main window of the Ethernet configuration screen is shown in Figure 59.
