Ngrep external machine

I have a machine which sends values to port 2712. Locally I use:

 ngrep -d lo '' 'port 2712'

Which shows me the values:

   U 192.168.122.103:51027 -> 192.168.122.103:2712 
     0.5

How can I from a machine in the same LAN listen to the same port on the 192.168.122.103 machine?

Solution 
  • ngrep -d any '' port 2712 and host 192.168.122.103

    If you know the specific interface (e.g. eth0), use that instead of any.
