If you want to disable IPv6, see IPv6#systemd-networkd.Note that Type=ether will also match virtual Ethernet interfaces ( veth*), which may be undesirable. Type=ether for Ethernet, Type=wlan for Wi-Fi and Type=wwan for WWAN. Devices can also be matched by their type.It is also possible to use a wildcard, e.g.See Network configuration#Network interfaces for checking your adapter names. These names can be different on different systems. In the examples below, enp1s0 is the wired adapter and wlp2s0 is the wireless adapter.The options specified in the configuration files are case sensitive.Use networkctl list to list the devices on the system.Īfter making changes to a configuration file, restart rvice. Systemd/udev automatically assigns predictable, stable network interface names for all local Ethernet, WLAN, and WWAN interfaces. For a full listing of options and processing order, see #Configuration files and work(5). to wait for enp1s0, disable rvice and enable systemd-networkd-wait-online(8) for more details.Īll configurations in this section are stored as foo.network in /etc/systemd/network/. etc/systemd/system//nf ĮxecStart=/usr/lib/systemd/systemd-networkd-wait-online -anyĪlternatively, use to wait for a specific interface. To change the behaviour to wait for any interface rather than all interfaces to become online, edit the service and add the -any parameter to the ExecStart line: This may cause an unwanted delay in the startup process. if you have a dual-port Ethernet card, but only one cable plugged in), starting rvice will fail after the default timeout of 2 minutes. If your system has multiple network interfaces, but some are not expected to be connected all the time (e.g. See also systemd#Running services after the network is up.īy default, rvice waits for all links managed by systemd-networkd to be fully configured or failed, and for at least one link to be online. The latter has WantedBy=network-online.target, so it will be started only when network-online.target itself is enabled or pulled in by some other unit. Note that systemd-resolved can also be used without systemd-networkd.Įnabling rvice also enables rvice, which is a oneshot system service that waits for the network to be configured.(by setting ( DHCP= and/or IPv6AcceptRA= in the section, and UseDNS=yes (the default) in the corresponding section(s), ,, see work(5)). systemd-resolved is also required if you want to obtain DNS addresses from DHCP servers or IPv6 router advertisements.systemd-resolved is required if DNS entries are specified in.It is important to understand how nf and systemd-resolved interact to properly configure the DNS that will be used, some explanations are provided in systemd-resolved.It is optional to also configure systemd-resolved, which is a network name resolution service to local applications, considering the following points: You can find a list of the currently running services with systemctl -type=service and then stop them. Note: You must ensure that no other service that wants to configure the network is running in fact, multiple networking services will conflict.
