| ===Use ifconfig to find your IP address===
| | | |
| * In Windows, you use i<font color=blue>p</font>config. In Linux, you use i<font color=read>f</font>config.
| | |- |
| * The ifconfig command will show you your IP address and MAC address as well as how many packets have been sent/received.

| ===Using Ethernet=== | | |- |
| The Linux OS used on the RZ boards brings up the Ethernet interface automatically during startup. This is done by the "systemd-networkd" service that is automatically start each time you boot. If your RZ board is connected to a network that has a DHCP server, the board will obtain an IP address from it automatically. You just need to execute ‘ifconfig’ to see what the assigned IP address is.
| | | colspan="2"| <br> |
| <pre> | | |} |
| $ ifconfig
| |
| </pre> | |
| | |
| In some scenarios the Ethernet interface may not be active (meaning "systemd-networkd" is not started or used). In this case, you would enter the follow to enable it and use the ifconfig to show what interfaces are active.
| |
| <pre> | |
| $ ifconfig
| |
| $ ifconfig eth0 up
| |
| $ ifconfig
| |
| </pre> | |
| | |
| After the interface is enabled, you will need to assign an IP address. You can either do that manually or use DHCP if it is available on the network.
| |
| | |
| Manual:
| |
| <pre> | |
| $ ifconfig eth 1925.168.0.55
| |
| </pre> | |
| | |
| DHCP:
| |
| <pre> | |
| $ udhcpc -i eth0
| |
| </pre> | |
| | |
| NOTE: After ‘ifconfig eth0 up’, you may notice that it already has an IPv6 address even though it doesn’t have a IPv4 address yet. No one really assigned that IPv6 address. In IPv6, you can always assign yourself a 'link local' address by just taking your MAC address and putt putting "fe80" at the beginning and "fe00" in the middle.
