See also /Wireless#Get the name of the interface. Wireless device names can also be retrieved using iw dev. Note that lo is the virtual loopback interface and not used in making network connections. Listing network interfacesīoth wired and wireless interface names can be found via ls /sys/class/net or ip link. Tip: To change interface names, see #Change interface name and #Revert to traditional interface names. Also note that ip commands can generally be abbreviated, for clarity they are however spelled out in this article.īy default udev assigns names to your network interface controllers using Predictable Network Interface Names, which prefixes interfaces names with en (wired/ Ethernet), wl (wireless/ WLAN), or ww ( WWAN). For persistent configuration, you can use a network manager or automate ip commands using scripts and systemd units. Be aware that configuration made using ip will be lost after a reboot. Iproute2 is a dependency of the base meta package and provides the ip(8) command-line interface, used to manage network interfaces, IP addresses and the routing table. Deprecated commandįor a more complete rundown, see Deprecated Linux networking commands and their replacements. net-toolsĪrch Linux has deprecated net-tools in favor of iproute2. Note: The installation image uses systemd-resolved and systemd-networkd, which is configured as a DHCP client for Ethernet, WLAN and WWAN network interfaces. Plug in the Ethernet cable or connect to the wireless LAN. Ensure your network interface is listed and enabled.To set up a network connection, go through the following steps: You can run a traceroute to further diagnose the route to the host. If you receive an error message (see ping error indications) or no reply, this may be related to incomplete configuration, but also your default gateway or your Internet Service Provider (ISP). Note that computers can be configured not to respond to ICMP echo requests.

For more information see the ping(8) manual. Ping is used to test if you can reach a host.

Check if you can resolve domain names (e.g.

9.9.9.9, which is a DNS server operated by the Quad9 Foundation and is a convenient address to test with).

You can ping a public IP address (e.g.

Your routing table is correctly set up.

Your network interface has an IP address.

The cable is plugged in or you are connected to the wireless LAN.

Otherwise, check the device driver – see /Ethernet#Device driver or /Wireless#Device driver. Your network interface is listed and enabled.To troubleshoot a network connection, go through the following conditions and ensure that you meet them:
