All devices and configuration options outside of the Group Restriction Type are secured from unauthorized access.
Clear the Credentials
Global credentials are credentials that HP Web Jetadmin uses for any device; they are an easy way for you to enter common credentials up front. Global credentials can be set for SNMPv1 Get Community Name, SNMPv1 Set Community Name, SNMPv3 Credentials, and EWS Password. If these credentials have been set, and device operations (for example, device configuration) require credentials, then the global credential will be tried. If the operation succeeds for the devices with the global credential, that global credential will be stored with the device. It still remains a global credential for other devices, but now that specific device has a working credential stored with it.
For example: User “A” enters global credentials for SNMPv1 Get Community Name as “mine” and “yours”. User “B” tries to interact with device “X”, which has a community name already set. HP Web Jetadmin first tries global credentials “yours” and “mine”; “yours” works. “Yours” is the stored as a regular credential for device “X”. The next time any user tries to interact with device “X”, HP Web Jetadmin will use the regular credential for that device (which is now “yours”) and will ignore any global credentials. However, if the regular credential “yours” becomes out of date, this process starts over again.
Following are steps to configure this option:
1.On the top menu bar, access Tools > Options > Shared > Credentials > General.
2.Configure the desired settings:
●Clear global credentials: Clears every temporary, global,
●Clear all stored credentials: Clears every temporary, global,
3.You must then confirm or cancel your request.
Manage the Global SNMPv1 Get Community Names
The SNMP Get Community Name object is configurable from within security settings. It can actually cause a device to disappear. For example:
User A is running an instance of HP Web Jetadmin known as Web Jetadmin A. This user is managing a set of devices that are also being managed by User B. User B is running another copy of HP Web Jetadmin known as Web Jetadmin B. This B copy of HP Web Jetadmin is being used at the help desk.
User B tries to provide a measure of security by changing the default Get Community Name on the set of devices from public to private using HP Web Jetadmin. User A opens HP Web Jetadmin and notices that all the devices have become
CAUTION: Changing the Get Community Name can cause devices to become unresponsive to management applications such as HP Web Jetadmin. The SNMP protocol will no longer respond to public queries and other management applications on the network will not be able to communicate with these devices.
Following are steps to configure this option:
1.On the top menu bar, access Tools > Options > Shared > Credentials > Device > SNMPv1 Get Community Name.
2.To add a community name, click Add and type the community name. Enter an associated (or easier) name in Remember credential as and click OK.
3.To remove a Get Community Name, click Remove.
