NAME

org.freedesktop.network1 - The D-Bus interface of systemd-networkd

INTRODUCTION

systemd-networkd.service(8) is a system service that manages and configures network interfaces. This page describes the D-Bus interface.

THE MANAGER OBJECT

The service exposes the following interfaces on the Manager object on the bus:

node /org/freedesktop/network1 {
  interface org.freedesktop.network1.Manager {
    methods:
      ListLinks(out a(iso) links);
      GetLinkByName(in  s name,
                    out i ifindex,
                    out o path);
      GetLinkByIndex(in  i ifindex,
                     out s name,
                     out o path);
      SetLinkNTP(in  i ifindex,
                 in  as servers);
      SetLinkDNS(in  i ifindex,
                 in  a(iay) addresses);
      SetLinkDNSEx(in  i ifindex,
                   in  a(iayqs) addresses);
      SetLinkDomains(in  i ifindex,
                     in  a(sb) domains);
      SetLinkDefaultRoute(in  i ifindex,
                          in  b enable);
      SetLinkLLMNR(in  i ifindex,
                   in  s mode);
      SetLinkMulticastDNS(in  i ifindex,
                          in  s mode);

      SetLinkDNSSEC(in  i ifindex,
                    in  s mode);
      SetLinkDNSSECNegativeTrustAnchors(in  i ifindex,
                                        in  as names);
      RevertLinkNTP(in  i ifindex);
      RevertLinkDNS(in  i ifindex);
      RenewLink(in  i ifindex);
      ForceRenewLink(in  i ifindex);
      ReconfigureLink(in  i ifindex);
      Reload();
      DescribeLink(in  i ifindex,
                   out s json);
      Describe(out s json);
    properties:
      readonly s OperationalState = '...';
      readonly s CarrierState = '...';
      readonly s AddressState = '...';
      readonly s IPv4AddressState = '...';
      readonly s IPv6AddressState = '...';
      readonly s OnlineState = '...';
      @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
      readonly t NamespaceId = ...;
      @org.freedesktop.DBus.Property.EmitsChangedSignal("false")
      readonly u NamespaceNSID = ...;
  };
  interface org.freedesktop.DBus.Peer { ... };
  interface org.freedesktop.DBus.Introspectable { ... };
  interface org.freedesktop.DBus.Properties { ... };
};

Provides information about the manager.

Properties

NamespaceId contains the inode number of the network namespace that the network service runs in. A client may compare this with the inode number of its own network namespace to verify whether the service manages the same network namespace.

NamespaceNSID contains the "nsid" identifier the kernel maintains for the network namespace, if there's one assigned.

      RevertNTP();
      RevertDNS();

EXAMPLES

Example 1. Introspect org.freedesktop.network1.Manager on the bus

$ gdbus introspect --system \
  --dest org.freedesktop.network1 \
  --object-path /org/freedesktop/network1

Example 2. Introspect org.freedesktop.network1.Link on the bus

$ gdbus introspect --system \
  --dest org.freedesktop.network1 \
  --object-path /org/freedesktop/network1/link/_11
