Edit: I am talking about the notify function here.

if you put "client min protocol = SMB2" in smb.conf, you get the same result.
Now with the wannacry virus going on, many people are turning off SMB1, so this surely is a problem for many people.

If I put "client min protocol = SMB2" and "client min protocol = SMB3" under [global] in smb.conf I can connect and get no errors. But there is nothing being reported changed. With SMB1 on, it works fine.

This is an upstream limitation of smbclient which only implements notify for smb1

With 2.0.3 you should at least get a relevant error message

I can confirm this.
With smbclient 4.3.11 (it is the default for Ubuntu 16.04) or 4.7.6 (Ubuntu 18.04) and smb2 the notify command returns with _ NT_STATUS_REVISION_MISMATCH_

With an smbclient 4.9.3 and smb2 the notify command works.

But what is the first smbclient version which supports notify with smb2?

You can test your version of smbclient with:

smbclient //server/share -U user -m SMB2

then type:

notify <foldername>

If your version supports notify with smb2 the output will be empty until a change event occur.

Maybe I found the first working smbclient version.
For smbclient 4.7.8 the release note contains something like
BUG #13382: smbclient: Fix broken notify.

Can somebody confirm this with a smbclient 4.7.8?

works for me with version 4.10.8 and even SMB3 as well.
