You can use this interface to query network state and the details of network interfaces like current IP addresses or DHCP options, and to activate, deactivate, created, edit, and delete saved network connections. Check the D-Bus API reference: STABLE DEVEL libnm API libnm wraps the D-Bus API in easy-to-use GObjects and is often much simpler for glib-based applications to use. https://networkmanager.dev/docs/man-pages/ Mon, 01 Jan 0001 00:00:00 +0000 https://networkmanager.dev/docs/man-pages/ This page contains a collection of man pages for NetworkManager.

A VPN plugin consists of the editor dialog and a D-Bus service that manages the actual VPN connection. VPN plugins maintained in GNOME This is a list of VPN plugins that are maintained as GNOME projects: NetworkManager-fortisslvpn (releases) Fortinet SSLVPN compatible NetworkManager-libreswan (releases) IPsec IKEv1 VPN, Cisco compatible NetworkManager-openconnect (releases) Cisco AnyConnect, Juniper NetworkManager-openvpn (releases) OpenVPN NetworkManager-pptp (releases) PPTP, Microsoft compatible NetworkManager-sstp SSTP compatible VPN plugin NetworkManager-vpnc (releases) IPsec VPN, Cisco compatible Natively Supported by NetworkManager WireGuard NetworkManager 1. https://networkmanager.dev/docs/rfkill/ Mon, 01 Jan 0001 00:00:00 +0000 https://networkmanager.dev/docs/rfkill/ The rfkill subsystem in Linux provides a mechanism to disable radio transmitters, as Wi-Fi, Bluetooth cards or WWAN modems installed in the system. From the kernel point of view, such devices typically have a associated rfkill device (also called killswitch) that is visible in the output of the rfkill utility. $ rfkill ID TYPE DEVICE SOFT HARD 0 bluetooth tpacpi_bluetooth_sw blocked unblocked 2 wlan phy0 blocked unblocked Each rfkill device has a type (bluetooth, wlan, wwan) and two flags to indicate whether the killswitch is hard-blocked (when radio transmission is blocked via a hardware switch) or soft-blocked (when radio is disabled but can be re-enabled in software). https://networkmanager.dev/blog/networkmanager-1-44/ Thu, 10 Aug 2023 08:00:00 +0000 https://networkmanager.dev/blog/networkmanager-1-44/ Half a year and 796 commits since NetworkManager 1.42, a new release is ready: NetworkManager 1.44. Let’s take a look at the most interesting parts! The ifcfg-rh plugin is deprecated The ifcfg-rh plugin is deprecated; it will only receive bugfixes and no new features. A warning is emitted to the log when a connection in ifcfg-rh format is found. In addition, to automatically migrate existing ifcfg-rh connections to the keyfile format, a new configuration option main. https://networkmanager.dev/blog/networkmanager-1-42/ Fri, 10 Feb 2023 08:00:00 +0000 https://networkmanager.dev/blog/networkmanager-1-42/ Half a year and almost 800 commits since NetworkManager 1.40, a new release is ready: NetworkManager 1.42. Let’s take a look at the most interesting parts! IEEE 802.1X support in nmtui nmtui is a screen-oriented configuration tool for NetworkManager. While not nearly as powerful as nmcli, its command-line based equivalent, it certainly has its niche of users. In the new version, nmtui gained support for configuring IEEE 802.1X. IEEE 802.1X is an authentication method most commonly utilized by secure enterprise Wi-Fi networks. https://networkmanager.dev/blog/using-python-and-networkmanager-to-control-the-network/ Fri, 16 Sep 2022 01:00:00 +0200 https://networkmanager.dev/blog/using-python-and-networkmanager-to-control-the-network/ This article first introduces the API of NetworkManager and presents how to use it from a Python program. In the second part it shows some practical examples: how to connect to a wireless network or to add an IP address to an interface programmatically via NetworkManager.

When programming such client applications it is therefore helpful to understand D-Bus. It took me a long time of try and error to get an understanding of how D-Bus works. I hope to share some of the things I learned and give my perspective about D-Bus. Useful links Much is already written. Some useful links here. https://networkmanager.dev/blog/networkmanager-1-40/ Thu, 25 Aug 2022 15:00:00 +0200 https://networkmanager.dev/blog/networkmanager-1-40/ This is the announcement for the new 1.40.0 NetworkManager release. The tarball can be found on our download page page. This release comes a bit more than 3 months after 1.38.0 release and contains about 600 patches from 29 contributors. See the NEWS file for a list of noteworthy changes and some highlights below. nmcli Offline Commands nmcli now supports an --offline flag, which can process connection profiles in keyfile format without requiring the NetworkManager daemon. https://networkmanager.dev/blog/networkmanager-1-38/ Fri, 13 May 2022 11:29:07 +0200 https://networkmanager.dev/blog/networkmanager-1-38/ A new release of NetworkManager, everybody’s favorite Linux network management service, has been released and is available for download from our download page. It’s also likely to be included in your favorite Linux distribution soon. If you’re a sort of person that’s curious enough to read about a new release of a networking management daemon then read on. This article points out some of the most interesting changes in the release and it has been written just for you (and some others). https://networkmanager.dev/blog/from-ifcfg-to-keyfiles/ Fri, 29 Apr 2022 01:00:00 +0200 https://networkmanager.dev/blog/from-ifcfg-to-keyfiles/ One of the changes in Fedora Linux 36 is that new installations will no longer support the ifcfg files to configure networking. What are those and what replaces them? Read more on Fedora Magazine https://networkmanager.dev/blog/networkmanager-1-36/ Thu, 24 Feb 2022 12:00:00 +0100 https://networkmanager.dev/blog/networkmanager-1-36/ This is the announcement of major release NetworkManager 1.36.0 on 24th February 2022. It comes six weeks after the previous major release. See what is new. Rework IP Configuration The way NetworkManager handles IP configuration internally was heavily reworked. The goal was more maintainable and extendable code (see here). This was a huge rework, but the goal is that it has little visible impact to the user. In the best case, everything still works the same – or better. https://networkmanager.dev/blog/networkmanager-1-34/ Thu, 13 Jan 2022 12:00:00 +0100 https://networkmanager.dev/blog/networkmanager-1-34/ Please welcome 1.34.0, the new major release of NetworkManager. Here are some of the changes that it brings. More privilege separation The new release introduces a new service named nm-priv-helper. At the moment its functionality is very limited, but the idea is that NetworkManager will perform every operation that requires elevated privileges by asking the new service via D-Bus. The goal is to drop more capabilities from the NetworkManager service. https://networkmanager.dev/blog/networkmanager-1-32/ Wed, 16 Jun 2021 12:00:00 +0100 https://networkmanager.dev/blog/networkmanager-1-32/ Four months after 1.30 release, please welcome 1.32.0, the new major release of NetworkManager. Here are some of the changes that it brings. Firewall Mode and nftables When activating a “shared” profile, NetworkManager will enable NAT for IPv4. Until now, it could only call iptables to configure masquerading. With this new version, it can also configure nftables for the same purpose. The firewall backend can be configured via the new [main]. https://networkmanager.dev/blog/networkmanager-1-30/ Thu, 18 Feb 2021 12:00:00 +0100 https://networkmanager.dev/blog/networkmanager-1-30/ Two months and a half after the previous release, NetworkManager 1.30 has seen the light today. The development cycle was shorter compared to past releases and therefore the list of new features is not as exciting as usual. There is however interesting stuff worth mentioning. Create your veth interfaces with NM A virtual Ethernet (veth) is a special kind of network interface supported by the Linux kernel. It is virtual because it doesn’t represent a hardware device. https://networkmanager.dev/blog/initscripts-ifcfg-rh-format-in-networkmanager-and-its-future/ Tue, 02 Feb 2021 12:00:00 +0100 https://networkmanager.dev/blog/initscripts-ifcfg-rh-format-in-networkmanager-and-its-future/ Let’s take a look at the history and future of the ifcfg-rh format.
