Dear Samba community,
My name is Mengxing Cheng and I am HPC system admin at the University of Chicago. We run Samba 3.6.23-25 on Red Hat Enterprise Linux Server release 6.7. We would like to completely close v1 as suggested by the campus security team.
The problem is that, though we have specify min protocol = SMB2 in the [global] section of smb.conf, some v1 communications as follows still appear in the packet captures on the AD controllers.
SMB:C; Negotiate, Dialect = PC NETWORK PROGRAM 1.0, MICROSOFT NETWORKS 1.03
SMB:R; Negotiate, Dialect is NT LM 0.12(#9), SpnegoToken(126.96.36.199.5.5.2)
Does anyone know how to completely disable v1 protocol?
