Instructions

Unity OE 5.4 -versiossa otettiin käyttöön uusi parametri cifs.smb2.smb3only SMB2-protokollan ottamiseksi käyttöön tai poistamiseksi käytöstä CIFS NAS -palvelimessa.

1. Kun asetus on cifs.smb2.smb3only=0 (oletus), SMB2-protokolla on käytössä CIFS NAS -palvelimessa. SMB2-asiakas ja SMB3-asiakas voivat käyttää CIFS NAS -palvelinta.

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. Kun asetus on cifs.smb2.smb3only=1 (oletus), SMB2-protokolla on poistettu käytöstä CIFS NAS -palvelimessa. Vain SMB3-asiakas voi käyttää CIFS NAS -palvelinta.

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. Kuinka muokata cifs.smb2.smb3only

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

nas01 : done

Huomautus: Tämä on NAS-palvelintason parametri, ja kun sitä muutetaan, se tulee voimaan välittömästi.
