SNMP settings

2023-12-12T14:48:18Z

Pa-P:

This function enables you to configure access over the '''SNMP''' protocol in versions 2 or 3.

With SNMP enabled, you receive a wealth of information (CPU usage, system load, memory info, ethernet traffic, running processes). System location and system contact are only for your information.  For example, when you connect from an SNMP client, you will see your location and name.

SNMP, version 3 has an encrypted transmission feature as well as authentication by username and password. SNMP, version 2 does not have encrypted transmission, and authentication is done only via the community string.

The community string you set can contain up to 20 characters, while the password needs to have at least 8 characters.

Links to SNMP clients:

*[http://www.muonics.com http://www.muonics.com]
*[http://www.mg-soft.com http://www.mg-soft.com]
*[http://www.manageengine.com http://www.manageengine.com]

{{Note|
Our storage system supports the SNMP protocol in MIB-II standard.  List of MIBs:

*- mib-2.host

*- mib-2.ip

*- mib-2.tcp

*- mib-2.udp

*- mib-2.interfaces

*- mib-2.at

*- system
}}

JovianDSS offers additional SNMP values to monitor Pool and ZFS attributes. It is necessary to query specific OIDs in order to receive those attributes.

For basic ZFS parameters, NYMNETWORKS-MIB mib is included:

*to version v.1.0 up29r4  [[:Media:NYMNETWORKS-MIB.txt|NYMNETWORKS-MIB.txt]]
*from version v.1.0 up30 [[:Media:NYMNETWORKS-MIB-up30.txt|NYMNETWORKS-MIB.txt]]

Additional information, like compression ratio, deduplication ratio, available space (in bytes), age (in seconds) of latest snapshot on volume, can be obtained with standard NET-SNMP-EXTEND-MIB:

JBODs & JBOFs

2023-11-02T07:46:05Z

Pa-P: Created page with "This functionality is available in the '''Storage Settings > JBODs & JBOFs''' tab It’s used to obtain more information about the disks in the JBOD or JBOF by using extern..."

This functionality is available in the '''Storage Settings > JBODs & JBOFs''' tab

It’s used to obtain more information about the disks in the JBOD or JBOF by using external services, e.g. Redfish. For this reason, it is dedicated to disks enclosures with out-of-band management.

The functionality only works on currently supported devices such as '''VORTEX SHELF'''.

In the case of VORTEX SHELF, the Redfish service is used to gain more information about disks, so an account with this service will be needed. To link an enclosure to the service, click on the "'''Add device'''" button. A pop-up with a form will appear. Fill in the form.

To link a device through the service, the following information must be provided:

*'''Name (alias)''' - Set a name for the enclosure that allows the device to be recognized should there be a few machines of the same model.
*'''IP address / domain''' - The domain name or IP address connecting the device to the network.
*'''Port''' - Enter the number of the port used to communicate with the device through the Redfish service. The default port number is 443. Change as needed.
*'''Username''' - Enter the username to the Redfish service.
*'''Password''' - Enter the password that’s associated with the user name that’s been entered above.

After filling in every field, click the "'''Add'''" button. The system will then connect to the service and start to scan all the available disks. This may take some time. The system needs a while to scan a disk. Thus the more disks there are in an enclosure, the more time is needed to scan them all. After all the disks are scanned, the information will be available in the disk details section. Additional data such as:

*Name of the enclosure in which the disk is located,
*Number of the slot in which the disk is located

will also be displayed generally (i.e., in pool's disk groups, pool wizard, etc.).

'''NOTE!''' When the connection status changes, a rescan of all disks is required. This occurs, e.g.:

*When a device configuration is changing,
*When the system is restarted,
*After network reconnection (when the connection has been lost), etc.

The connection status of the enclosure is displayed in the table in the "'''JBODs & JBOFs'''" tab at all times. Next to the connection status there’s a power state displayed that shows if the device is turned on. Every device that has been added can be edited, removed from the table, or selected to display its details.

To do any of the above, use the context menu. The “'''Edit'''” option allows changing the device’s data or credentials. The “'''Details'''” option shows more information about an enclosure such as:

*Name (alias)
*Model
*Vendor name

The “'''Remove'''” option leads to the removal of a device from the table. Removing a device causes it to disconnect from the external service. Any additional information uploaded via the service after removing a device will not be displayed. In some cases, the option to turn on the LED for disks in the JBOD/JBOF may also become disabled.

Lightweight Directory Access Protocol

2022-05-30T08:31:38Z

Pa-P:

This functionality is available in: '''User Management''' > '''Share users/group'''s > '''Authorization protocols''' > '''Lightweight Directory Access Protocol (LDAP)'''

To create and manage a database on a local server, the following information is required:

*'''LDAP domain name''': The name must start with 'dc=' and contain only alphanumeric characters (a-zA-Z 0-9-_.). It cannot begin or end with a space or have several spaces in a row.
*'''Password''': The minimum length of the password is 6 characters.

 '''NOTE''': When mounting the given share with LDAP credentials, please use the following syntax:

*Accessing share: \\server_ip\share_name
*Username: workgroup\username (“Username" must consist of workgroup and actual user name)
*Password: secret pass

The workgroup and username are defined by the system administrator.

'''See Also:  '''[http://wiki.open-e.com/default/wiki/SMB_service SMB service]

A unique ID (UID) is assigned to each new user in the database. Similarly, a unique ID (GID) is assigned to each new user group. Once assigned, the UID or GID cannot be reused, even if the user or user group no longer exists in the database until said database is reset. You can create 899,999 unique users (UIDs) and 99,486 unique user groups (GIDs).

'''To connect to the local LDAP database using an external server, the LDAP client must''':

*use the '''TLS''' protocol with an encrypted connection on '''port 389'''
*accept '''self-signed certificates'''

Below you’ll find an example showing what connecting to the local LDAP database looks like. The "LDAP domain name" is set as "dc=internal,dc=lan": '''Host''': IP or domain name of the server, e.g. 192.168.174.100 '''Port''': 389 (with enabled TLS encryption) '''Base DN''': dc=internal,dc=lan '''Un-K DN''': cn=admin,dc=internal,dc=lan '''Users base DN''': ou=people,dc=internal,dc=lan '''Groups base DN''': ou=groups,dc=internal,dc=lan
