Instructions

Ab Unity OE 5.4 wurde der neue Parameter cifs.smb2.smb3only eingeführt, um das SMB2-Protokoll auf dem CIFS-NAS-Server zu aktivieren/deaktivieren.

1. Wenn "cifs.smb2.smb3only=0" (Standardeinstellung) festgelegt ist, wird das SMB2-Protokoll auf dem CIFS-NAS-Server aktiviert. Auf den CIFS-NAS-Server kann über den SMB2-Client und den SMB3-Client zugegriffen werden.

root@vsa0 spa:/cores/service/user# svc_nas nas01 -param -f cifs -i smb2.smb3only -v

nas01 :
name                    = smb2.smb3only
facility_name           = cifs
default_value           = 0
current_value           = 0
configured_value        = 0
param_type              = NAS server
user_action             = none
change_effective        = immediate
range                   = (0,1)
description             = Specifies if SMB2 2XX dialects are disabled.

detailed_description
This parameter allows the disabling of SMB2 2XX dialects (SMB2.0/SMB2.0.2, SMB2.1 and SMB2.2). SMB2 is not disabled by default, as the default value is set to 0. Note: The SMB clients must disconnect all the SMB server shares in order to negotiate the appropriate dialect after modifying this parameter.

2. Wenn die Option "cifs.smb2.smb3only=1" (Standardeinstellung) festgelegt ist, ist das SMB2-Protokoll auf dem CIFS-NAS-Server deaktiviert. Auf den CIFS-NAS-Server kann nur über den SMB3-Client zugegriffen werden.

root@vsa0 spa:/cores/service/user# svc_nas nas01 -param -f cifs -i smb2.smb3only -v

nas01 :
name                    = smb2.smb3only
facility_name           = cifs
default_value           = 0
current_value           = 0
configured_value        = 0
param_type              = NAS server
user_action             = none
change_effective        = immediate
range                   = (0,1)
description             = Specifies if SMB2 2XX dialects are disabled.

3. Ändern von cifs.smb2.smb3only

root@vsa0 spa:/cores/service/user# svc_nas nas01 -param -f cifs -m smb2.smb3only -v 1

nas01 : done

Hinweis: Dies ist ein Parameter auf NAS-Serverebene, der nach seiner Änderung sofort wirksam wird.
