SNMP error with port already in use

I have created a SNMP agent simulator application which use the port number 161 for the simulated devices. sometimes it occurs the port alredy in use exception. how can i know if the 161 port is busy or not?

Solution

  • By using netstat command.

    Specifically,

    netstat -s [PORT_NO]

    For example,

    netstat -s 161
