Hey @Manouchehri -- I wonder if this is the same underlying issue as #185 . In which case the fix described there should fix this issue too.

There are a lot of good fixes and tricks in this bugtracker that are sometimes hidden amidst the bugs. I recently put up a new forum and have been trying to accumulate them there. The particular relevant fix is here:

http://wsl-forum.qztc.io/viewtopic.php?f=6&t=6

Let me know if it's helpful; also feel free to add to it if I've missed anything.

@Manouchehri - Regarding NETLINK sockets, they are currently not fully supported in WSL and we are looking into getting it into a more complete state. Thanks for trying out WSL and the feedback.

Just an update that network interface enumeration through NETLINK sockets has been working since the last couple of release builds. I tried the repro and it seems to be fixed. I am marking this one as fixed, and will close it out soon. If the issue persists, please let us know or re-open.
