To require samba clients running 'smbclient' to use
packet signing, add the following to the '[global]' section
of the Samba configuration file, '/etc/samba/smb.conf':
'client signing = mandatory'
Requiring samba clients such as 'smbclient' to use packet
signing ensures they can
only communicate with servers that support packet signing.
Parameter:
[mandatory/auto/disabled]
Technical Mechanism:
Packet signing can prevent
man-in-the-middle attacks which modify SMB packets in
transit.
