Instructions

Unity OE 5.4부터 CIFS NAS 서버에서 SMB2 프로토콜을 활성화/비활성화하는 새로운 매개변수 cifs.smb2.smb3only가 도입되었습니다.

1. cifs.smb2.smb3only=0(기본값)으로 설정하면 CIFS NAS 서버에서 SMB2 프로토콜이 활성화됩니다. CIFS NAS 서버는 SMB2 클라이언트와 SMB3 클라이언트가 액세스할 수 있습니다.

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. cifs.smb2.smb3only=1(기본값)로 설정하면 CIFS NAS 서버에서 SMB2 프로토콜이 비활성화됩니다. CIFS NAS 서버는 SMB3 클라이언트만 액세스할 수 있습니다.

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. cifs.smb2.smb3only를 수정하는 방법

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

nas01 : done

참고: 이는 NAS 서버 수준의 매개변수로, 일단 변경되면 즉시 적용됩니다.
