LinuxIPv4InterfaceProperties.get_IsDhcpEnabled throws NotSupportedException

[AgnesAarthy]

I am running the same code for getting the network informations in .Netcore 3.0. The Property System.Net.NetworkInformation.LinuxIPv4InterfaceProperties.get_IsDhcpEnabled() givs me the result wen it is Run in Windows Platform but throws the below issue in Linux Platform
Exception :
GetNetworkInterfaceInfo Failed: 'System.PlatformNotSupportedException:
The information requested is unavailable on the current platform.

at System.Net.NetworkInformation.LinuxIPv4InterfaceProperties.get_IsDhcpEnabled()

The depends on the particular distribution and it is not trivial to keep up with all of them. Furthermore, somebody can just start DHCP client on an interface and that would be even more difficult to detect.

Triage: It is useful information for developers. Unclear if it is possible to do -- as next step, we need someone with Linux expertise to do investigation if it is achievable at least on some distros and how.

Anyone interested to do the research?

You need to integrate with whatever is managing the network. For many distros it is NetworkManager. NetworkManager has a D-Bus API which you can use from .NET with Tmds.DBus. The example on the repo readme is using NetworkManager.

I agree, it cannot be implemented in a generic way on Linux.

Even if that is not complete, it may be an improvement if we can talk to NetworkManager via API. Embedded and unsupported distros can keep throwing PNSP.
