You can manage CIFS services from iManager. The recommended method to configure, manage, and modify CIFS properties and parameters is by using iManager.
NOTE:Admin equivalent/container admin users should be LUM-enabled in order to manage the CIFS server through the CIFS iManager plug-in. For more information, see Using iManager for Linux User Management
in the OES 23.4: Linux User Management Administration Guide.
Install the CIFS iManager plug-in. For details, see Section 4.5, Installing the CIFS iManager Plug-In.
Install CIFS on at least one OES server. For details, see Section 4.0, Installing and Setting Up CIFS.
Ensure that ndsd is running. Use systemctl status ndsd.service on the server console to check.
In a Web browser, specify the following in the address (URL) field:
http://server_IP_address/nps/iManager.html
where server_IP_address is the IP address of the server on which iManager is running.
For example:
http://192.168.0.1/nps/iManager.html
At the login prompt, specify the server administrator user name, password, and tree name or IP address of the tree, then click Next.
For more information on iManager administration, see the NetIQ iManager Administration Guide.
In the left pane of the iManager application, click File Protocols > CIFS.
The default CIFS parameters page is displayed. Use this page to configure and manage CIFS.
In the Server field, specify the OES server name.
or
Browse and select the server using the object selector.
or
Select the server from the object history list.
Verify the status of the server. If the CIFS server is stopped, click Start to start the CIFS server.
The information displayed changes to reflect the current state and properties of the selected server.
Continue with other administrative actions as necessary:
The server and authentication parameters can be set using the General and Share tabs on the default CIFS server page in iManager.
For information on starting iManager and accessing the CIFS server, see Section 5.1.2, Selecting a Server to Manage.
To change these parameters from command line, see Section 5.2.5, Modifying the CIFS Configuration.
The General page contains the Server and Authentication properties tabs. By default, the Server Properties page is displayed. View or edit the server parameters on this page.
NOTE:For a virtual server, only CIFS Virtual Server Name and Comment are not inherited from the physical server. Hence, only these parameters can be edited for CIFS on a shared pool server.
Table 5-1 CIFS Server Page Parameters
|
Parameter |
Description |
|---|---|
|
CIFS Virtual Server Name |
The name of the server running CIFS services. The length can be a maximum of 15 characters. The default server name is the OES server name. If OES host or a cluster resource is joined to domain and you need to rename this parameter, then follow the procedure provided at Renaming the Netbios Name of OES Host or Cluster Resource in the OES 23.4: NSS AD Administration Guide. |
|
WINS IP Address |
The address of the WINS server. |
|
Comment |
The text in the Comment field is displayed when viewing details of the server. This can be useful if you want to provide a more detailed description of the server. The maximum length is 47 characters. IMPORTANT:You should use single-byte characters in comments. Double-byte characters are not supported. |
|
OpLocks (Opportunistic Locking) |
Improves file access performance. The option is enabled by default. |
|
This option enables Distributed File Services support in CIFS. The option is disabled by default. |
|
|
SMB Signature |
This option is Disabled by default. Select Mandatory or Optional or Disabled. For details, see Enabling and Disabling SMB Signing. |
SMB signing is a security mechanism designed to improve the security of the CIFS protocol. With SMB signing, an authenticating signature is added by placing a digital signature into each SMB packet. The digital signature is then verified by both the client and the server. It can be set to mandatory or optional mode. For more information, see Microsoft Knowledge Base article.
SMB signing should be turned off when domain authentication is configured.
To use SMB signing mode, both the client and the server should be enabled for SMB signing. Use either Optional or Mandatory modes to enable it.
Optional mode: If SMB signing is set to the optional mode (the default mode after enabling it by using console commands), it automatically detects whether or not individual clients have SMB signing enabled. If a client does not have SMB signing enabled, the server does not use SMB signing for client communication. If a client has SMB signing enabled, the server uses SMB signing for client communication.
Mandatory mode: If you set SMB signing to mandatory mode, all clients must have SMB signing enabled or they cannot connect to the server. If SMB signing is set as mandatory on the server, clients cannot establish sessions with the server unless they have SMB signing enabled.
Disable mode: You can disable SMB signing by setting SMB signing to disabled mode.
IMPORTANT:After enabling or disabling SMB signing, or changing the mode to optional or mandatory, clients must reconnect in order for changes to take effect. For example, if SMB signing is enabled on the server, SMB signing is not in effect for individual clients until each of those clients reconnects.
On the General page, select Authentication to view or edit the CIFS authentication parameters. When third party domain authentication is selected, SMB signing is disabled.
The functionality of CIFS third party domain authentication in OES is as same as in NetWare.
Table 5-2 CIFS Authentication Page Parameters
|
Parameters |
Description |
|---|---|
|
Mode |
Indicates the method of authentication used by CIFS. CIFS uses either eDirectory (local) or third-party Domain authentication mechanisms.
IMPORTANT:If you change the modes from Local to Third Party Domain or from Third Party Domain to Local, restart the CIFS server for the changes to take effect. NOTE:Extended Security (NTLMSSP) and SMB2 are not supported for Third Party Domain mode authentication. For more information on enabling Third party domain authentication, see Section 5.5, Third-Party Domain Authentication. |
|
Work Group / Domain Name |
The workgroup or Windows domain to which the CIFS users belong. The domain name should be a valid DNS entry or the NetBIOS name of the domain. |
|
LMCompatibilityLevel |
NTLMv2 is an authentication protocol that is cryptographically stronger than NTLMv1. NTLMv2 is not negotiated between the client and the server. The protocol does not determine the challenge or response algorithms, so it must be configured on both the client and the server. On a Windows client set the LMCompatibilityLevel by modifying the Windows registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA. On the server ser the LMCompatibilityLevel by running the novcifs [-L 0|4|5| --lm=0|4|5] command. CIFS currently supports 0, 4, and 5 compatibility levels for NTLMv2. Select the appropriate LMCompatibilityLevel from the drop-down list.
NOTE:When the Accept NTLMv2 responses only option is selected and you are attempting to map a share from a Windows 7 or Windows 8 workstation, make sure you specify the domain name along with the user name for the mapping to be successful. |
|
Primary Domain Controller Name |
The name of the PDC server. This is needed if the PDC is on a different subnet. This option should be used only when there is a valid reason for overriding WINS or DNS. This field can be changed only if Third Party Domain is selected. |
|
Primary Domain Controller IP Address |
The PDC server’s static IP address. This is needed if the PDC is on a different subnet. This option should be used only when there is a valid reason for overriding WINS or DNS. This field can be changed only if Third Party Domain is selected. IMPORTANT:If this is not a static address, the server running CIFS services cannot contact the PDC when the PDC reboots and the address changes. |
The Share tab on the default CIFS server page in iManager displays the CIFS share details. Use the Shares page to add a new share on the server to be specified as a sharepoint and to be accessible via the Network Neighborhood. NSS Volumes are added by default.
