Instructions

Fra Unity OE 5.4 ble en ny parameter, cifs.smb2.smb3only, introdusert for å aktivere/deaktivere SMB2-protokollen på CIFS NAS-serveren.

1. Når angitt cifs.smb2.smb3only=0 (standard), er SMB2-protokollen aktivert på CIFS NAS-serveren. CIFS NAS-serveren kan nås via SMB2-klient og SMB3-klient.

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. Når den er angitt til cifs.smb2.smb3only=1 (standard), er SMB2-protokollen deaktivert på CIFS NAS-serveren. Du får bare tilgang til CIFS NAS-serveren via SMB3-klienten.

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.

Note: The SMB clients must disconnect all the SMB server shares in order to negotiate the appropriate dialect after modifying this parameter.

3. Hvordan endre cifs.smb2.smb3only

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

nas01 : done

Merk: Dette er en parameter på NAS-servernivå, og når den er endret, trer den i kraft umiddelbart.
