Adding more info, next future SAMBA version 4.7 will increase the SMB "client max protocol" to SMB3_11 to be able to connect to servers with SMB1 disabled, "client min protocol" is still SMB1.

It's possible to use the '-m/--max-protocol' option to overwrite the "client max protocol" option temporary. Note that the '-e/--encrypt' option also works with most SMB3 servers (e.g. Windows >= 2012 and Samba >= 4.0.0), so the SMB1 unix extensions are not required for encryption. The change to SMB3_11 as default also means smbclient no longer negotiates SMB1 unix extensions by default, when talking to a Samba server with "unix extensions = yes". As a result some commands are not available, e.g. posix_encrypt, posix_open, posix_mkdir, posix_rmdir, posix_unlink, posix_whoami, getfacl and symlink. Using "-mNT1" reenabled them, if the server supports SMB1. Note the default ("CORE") for "client min protocol" hasn't changed, so it's still possible to connect to SMB1-only servers by default. ###### -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1697817 Title: disable smb1 by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1697817/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
