Hi, I am trying to configure FBSD 4.8 to do an ethernet loopback test. I want to be able to sent packets over the ethernet interface, and a device hooked up to the ethernet port (at the very minimum, an RJ-45 loopback plug, i.e. with pins 1 & 3 and 2 & 6 connected together) This is to test a type of network transmitter. There exist a description of a test setup done using Linux here http://ronja.twibright.com/tetrapolis/testing.php, but applying the same principles does not seem to work on FBSD. Essentially, I would like to be able to ping the interface, and if the loopback plug is hooked up, then tcpdump should show the packets received, otherwise, nothing should be seen. Anybody knows how to do that ? I have been manipulationg arp tables and routes to no end, I do not see how to make this work. Any help appreciated bruno
