I need to test some software drivers for SNMP v2 protocol. I am not getting it clear whether this protocol supports BOOL tags or not. I am using this simulator (SNMP Agent simulator (https://ireasoning.com/download.shtml). How do I configure digital tag in this simulator ?

I have an issue where WiFi is not available on an Android device. We want to stream image data from the device using a websocket server (written using WebSocket++) through to the PC. However, I'm not sure if this is possible without operational WiFi. So, the position we are in is that we may only have the USB link available.
Someone today suggested we might be able to get Websockets working using adb port forwarding (see https://developer.android.com/studio/command-line/adb#forwardports), but I'm not sure if that's correct. Could this work, and what would that solution look like?
Are there any other reasonable options. I'm not certain if tethering is available on the device and if that could be another solution?
I have written a simple "Get" request in Delphi7 using the Indy10 TIdSNMP component but it returns an empty reply.
The target device's Agent doesn't support v1 SNMP so I have configured it for SNMP version 2c.
I know that the OID I am requestin is correct as I used a MIB Browser to obtain it from the same device using its MIB.
I vaguely recall seeing a comment on the forums that Indy 9 only supported SNMP version 1, so I am wondering that's still the case for Indy 10?
At this time, Indy 10 still does not support SNMP versions above v1. It is on the TODO list:
#56: Update TIdSNMP to support newer SNMP versions
I'm doing some polling of specific adapters on some PCs running windows via SNMP. I've noticed that polling using an OID constructed with the interface's ifIndex is unreliable as it appears that the ifTable is created dynamically.
I found some Cisco documentation that mentions that ifIndex is no longer persistent as of RFC2863. The documentation introduces a feature of Cisco routers that allows for ifIndex persistence between reboots.
Can such a thing be achieved in Windows? I want to avoid enumeration and identification of interfaces as it is impractical/difficult to do for my application
Unlike (newer, IOS 12+) Cisco devices, Windows does not have a fixed interface scheme.
The interface list is generated on boot and can change while running (think Wireless, dial-up, VPN, or tunneling interfaces; or link loss). That being said, on a stable Windows system the values should be consistent.
I would try the last known value, do a sanity check and re-enumerate the interfaces if it fails.
I'm trying to connect a Glucose and Heartrate monitor LE devices using Windows 8. It is being detected just fine and default LE is used for the device. I'm trying to use the sample BLE http://code.msdn.microsoft.com/windowsapps/Bluetooth-LE-Metro-sample-a2ba1b5b but getting 80070057 error.
I have read some post that a custom driver is required. I run it using the sample in Mac and it works just fine. The sample application was able to use the device without any issues. Is there a way to access and use the device without creating a custom driver?
Thanks!
The sample is just a facade to the user. Driver is always needed in order to communicate with hardware. For some standard devices the OS might include a default driver (e.g., standard Web cam) with a predefined set of functionality but for all the rest a vendor-supplied driver is required.
I need to implement an SNMP manager (client) to run on a vxworks embedded single board computer, in order to monitor and control some other Linux boards, each running an SNMP agents for reading and writing local data.
Windriver supplies an example called 'snmptalk' but with no help on how to use it or how to implement it on vxworks.
option 1. Port snmptalk to vxworks
Windriver supplies snmptalk ( located at: /vxworks...\demo\snmptalk...) but only for non-vxworks implementations.
option 2.
I called Windriver support and they gave me a sample of a working SNMP get and set, and it worked great. My vxworks code can now get and set from any SNMP agent on the network.
I have now implemented an embedded web site for my client, with pages in JavaScript, which can read and write data at any SNMP data object on the network, controlled by the user web page.
