Practically I'm looking for a way to view lagging connections, especially dns connections(udp:53).
The closest I've got was using
tcptrack as it shows idle time, but unfortunately it's only for tcp connections and there is no way to sort by idle time.
What is the simplest way to do this, practically I'm looking for a netstat command with a
connection duration/idle column. It can be a GUI as for now I just want to do some monitoring and see what's holding back.
