Detect a new network connection (linux-server) and it's status in java

Is there any way that java can detect that I have just plugged in a wired-network, and monitor it's bandwith? (I'm using linux, if that matters)

You can run the program

/sbin/ip monitor

And monitor its output using a pipe or whatever.

It will tell you when

  • New network interfaces are configured
  • Network interfaces go up and down because the network becomes ready / not ready (this typically works by detecting an ethernet carrier or wifi access point)

The output is somewhat confusing but should be parseable.

For the sake of simplicity and without using native code, you could try to using java.net.NetworkInterface with polling, so every X seconds you trigger a network interface enumeration in order to see if there are new interfaces.
