SocketException running on AspNet Core on Linux

[Luiz Tessarolli]

This code works fine on windows, but throws this error on linux.

I'm suspecting I might be missing some .deb's on the linux box, but not sure how to find out which..

Can you help me?

Thanks

Hi,

The only protocol I'm aware this needs is UDP. I'm afraid I'm not familiar with Linux, 'debs' or mono, and have no device(s) on which to test this so I'm not much help.

If there is a 'deb' to add UDP support then I guess try installing that, otherwise perhaps try Googling for that error details and mono and .net.

Sorry, that is not totally accurate... UDP is used primarily, but also HTTP which also requires TCP. In the error above it looks like (multicast) UDP is what is trying to be accessed though.
