I need to send a SNMPv2c trap to a port other than the default 162 however this fails with a trap (see below). From the code it looks like the port is hardcoded (in TrapSession)
def initialize(options = {})
options[:peername] = "#{options[:peername]}:162"
super(options)
end
when passing the port the peername becomes localhost:162:2006. If I remove the 162 everything works fine.
a = Net::SNMP::TrapSession.new(:peername => "localhost", :port => 2006, :community => "whatever", :version => "2c")
a.trap_v2(:oid => "1.3.6.1.6.3.1.1.4.1.0")
