Detect SMB Version about amsmb2

[amosavian]

I don’t get the question. This library is client and supports connecting to SMB2 server and its dialects.

Whether it is a SMB2 Server or not?

For example I tried connecting to a old server (Apple TimeCapsule) and it never returned anything. So my assumption is that it only supports SMBv1

[amosavian]

This library does not provide any way to detect server support. It only will return an error if server doesn’t support SMB2/3 protocol or fails to establish a connection.

You can use a SMB1 library like libdsm (or its objective-c wrappers) as fallback.

My problem is that it doesn't return an error, it only timeouts.

But I'm talking about a method to detect in general besides this library, if there is any (MacOS/Linux)

[amosavian]

Probably the server doesn’t return anything.

Well it could also be a slow connection or slow dns Server that is resolving a hostname. So I don't want to wait 2 minutes to find out whether I need SMBv1 or SMBv2/3

There has to be a way
How is the MacOS Finder then doing it? It always and instantly take the best Version?

[amosavian]

Of course there is. Please read this link to know how this can be done. But the underlying library (libsmb2) supports no protocol other than SMB2 protocol and its dialects and there is no intention to add SMB1/CIFS support. But you can use libdsm to add SMB1/CIFS support.
