Network protocol on SMB share, TCP or UDP?

I couldn’t find any specific info regarding the network protocol used when streaming files from an SMB Share. It is my understanding that it should be TCP port 445, is this the case for OSMC? I want to make sure that is not using UDP, if that is even possible.

Thank you very much!

Files are typically shared over TCP445, but other ports are involved in Samba (SMB) and it uses TCP and UDP for different purposes. See the link below for a little more detail:

It’s a little outdated, but still accurate for the most part. Obviously if you enable advanced services in Samba then you can expect it to use more ports for those too.
