Samba 4.11 Removes SMB1 File-Sharing Protocol Version By Default
Years late to the SMB1-killing party, Samba finally dumps the unsafe file-sharing protocol version by default

Samba says its next release will switch off previously on-by-default support for the aging and easily subverted SMB1 protocol. It can be reenabled for those truly desperate to use the godforsaken deprecated protocol version.

The open-source SMB toolkit's developers say the Samba 4.11 build, currently in preview, will by default set SMB2_02 as the earliest supported version of the Windows file-sharing protocol.

"This means clients without support for SMB2 or SMB3 are no longer able to connect to smbd (by default)," the 4.11 release notes read.
Admins will still have the option to allow SMB1 on their servers if they so choose, but support will be turned off by default.

The move by Samba to drop SMB1 can be seen as long overdue [...]
Since the Windows 10 1709 build back in 2017, both the desktop and server versions of Windows dropped support for SMB1, and as far back as 2016 Microsoft was urging admins to drop the protocol version altogether.
