Processing wrong values of MIB OID objects by SNMP agent


Processing wrong values of MIB OID objects by SNMP agent



How to make the SNMP agent ignore wrong or inconsistent value of supported generic MIB OID objects, and move ahead, not stumbling on them? Currently, the SNMP agent stumbles on errors in supported MIB OID objects, can't process and reject the configuration file. Although this behavior fully conform to DOCSIS 3.0 specification. But this behavior varies depending on the vendor.
(means there is an option to make error processing less strict).


8.2.4.2 CM configuration TLV-11 elements not supported by the CM

If any CM configuration file TLV-11 elements translate to SNMP MIB OIDs
that are not MIB OID elements supported by the CM, then the CM MUST
ignore those SNMP varbinds, and treat them as if they had not been
present, for the purpose of CM configuration. This means that the CM
will ignore SNMP MIB OIDs for other vendor's private MIBs as well as
standard MIB elements that the CM does not support." ... If any CM
configuration file TLV-11 element(s) are ignored, then the CM MUST
report them via the CM configured notification mechanism(s), after the
CM is registered.
...
8.2.4.4 CM state after CM configuration file processing failure

If any CM configuration file generated SNMP PDU varbind performs an
illegal set operation (illegal, bad, or inconsistent value) to any MIB
OID/instance supported by the CM, the CM MUST reject the configuration
file.

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false. I added itms-apps to my plist: LSApplicationQueriesSchemes and put this in my app delegate: func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return true } func moreTapped() { let url = NSURL(string: "itms-apps://itunes.com/developer/quantum-productions/id979315877") if #available(iOS 10.0, *) { UIApplication.shared.open(url! as URL, options: [:], completionHandler: {(success: Bool) in }) } else { UIApplication.shared.openURL(url! as URL) } } Are you testing on a real device? – rmaddy Jun 21 at 23:57 I try on a device, get "Cannot Connect to App Store".

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
