Instructions

Da Unity OE 5.4 è stato introdotto un nuovo parametro cifs.smb2.smb3only per abilitare/disabilitare il protocollo SMB2 sul server CIFS NAS.

1. Quando è impostato cifs.smb2.smb3only=0 (impostazione predefinita), il protocollo SMB2 è abilitato sul server NAS CIFS. È possibile accedere al server NAS CIFS dai client SMB2 e SMB3.

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. Quando è impostato cifs.smb2.smb3only=1 (impostazione predefinita), il protocollo SMB2 è disabilitato sul server NAS CIFS. Il server NAS CIFS è accessibile solo dal client SMB3.

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. Come modificare cifs.smb2.smb3only

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

nas01 : done

Nota: Si tratta di un parametro a livello di server NAS e, una volta modificato, avrà effetto immediato.
