Is there any SNMP manager or trap manger with buzzer notifications on PC normal speaker? With alarms that can be defined to activate this buzzer upon specific traps.
You can use NetDecision TrapVision for that. It comes with built-in trap handler that supports audible alarms.

I have configured a v3 SNMP trap and I have confirmed a trap is being received but the following error is appearing:
"RFC3414 ยง3.2.7.a Not in time window; engineID='', engineBoots=19, engineTime=60374
"
From various articles I can see it is due to the engineBoots and engineTime not being in sync between the sender and receiver of the trap.
Can someone recommend what is the best way to sync the sender and receiver of the trap?
I am new to SNMP and to Kapacitor-InfluxDB. I have InfluxDB and Kapacitor installed on a server. Kapacitor is generating alarms using data pushed into InfluxDB. I was wondering if it is possible to consider the server on which Kapacitor and InfluxDB are installed an SNMP agent and use the alarms that Kapacitor generates as traps to be sent to an SNMP manager installed on a separate machine?
Please let me know if my question is not clear.
You could implement it as an Output Node in Kapacitor: https://docs.influxdata.com/kapacitor/v0.13/about_the_project/custom_output/
Kapacitor can not natively send SNMP traps out of the box (yet). That functionality will likely require adding an SNMP trap event handler to the alert node.
Kapacitor's alert node exec event handler can be set to trigger a SNMP trap via snmptrap or another SNMP command line agent.
Is there any window API to catch the signals sent by the wireless mouse and keyboard ?
How far i know signals from this wireless device are always sent if it is connected but for the cabled mouse/keyboard , when we are moving the device only for that time signals are being sent ..Please correct me if i am wrong ..
If above is the case then please let me know any API to catch the signals sent by the wireless mouse/keyboard ?
Is there any window API
The Windows API (which is a user-mode API) doesn't care what kind of mouse you have: serial port, USB, wireless...
The mouse hardware connection is handled in the kernel, by a device driver.
In 802.11 WLAN, there is data rate change of the connection as Dynamic rate scaling or Automatic Rate Selection is working. Is there any event triggered from the card so as to notify the OS (Linux Kernel event) about the same?
I know something about "iw events". Unfortunately it does give events like association, authentication etc but not of the data rate changes.
Please let me know if anyone aware of such functionality on any wireless card.
Thanks, Kedar
TX or RX rate?
It also depends on what kind of driver is used. If the rate control algorithm is implemented in the firmware then likely it's not possible. If the driver uses mac80211 then you can create a monitor interface and use e.g. tcpdump:
% sudo iw phy0 interface add mon0 type monitor
% sudo ifconfig mon0 up
% sudo tcpdump -ni mon0
Then you'll also get quite some information about the PHY for each packet.
I am writing my own program, which will be running on a 802.11 AP, to capture all the outgoing beacons on the AP. But I just noticed I cannot do it with the current libpcap: the program couldn't capture any outbound beacons. I've also tried Wireshark which gave the same result.
My questions are:
Can anyone shed some lights on the causes of what I saw?
Is there any user space method that I can capture the outbound beacons of a 802.11 AP on that specific AP (rather than capturing on other PCs)? It is better for me if I can do this without hacking into the wireless driver.
I am using Ubuntu 10.04 as the OS, Madwifi as the wireless driver.
Thanks, folks.
I would guess that the WiFi chip is generating the beacons autonomously
so they never pass the driver-chip interface where libpcap intercepts
packets. You'll probably need a second radio to be able to capture the
beacons from the air (when the primary radio is busy sending a beacon
the receiver is turned off so it can't hear what it is transmitting).
You can Capture those packets(Beacon ,Acknowledgement,etc) in wireshark
all you need to do is following :
go to capture menu
after selecting your interface go to option
select the per packet information option in link layer type of your interface
press start
