What is dude server? is it the mikrotik routerOS software?

Hello,
I’m trying to start the dude, and when trying to connect to the remote mikrotik (with the IP and the port connection 8081) it doesn’t connects to it. I have just install the dude application software in my PC and then I’ve tryed to connect remotely to the mikrotik, but I have installed nothing to the remote mikrotik router. What have I to do? Thank you!!
Bye.

The DUDE software is a SNMP network management/monitoring suite. It allows you to monitor all mikrotik/SNMP based devices in your network.
