I am writing this e-mail at the recommendation of Alan Cox. I have an
embedded system running on cPCI HW which has two physical Ethernet
connections. This system is connected to an internal network and the IP
addresses are not made public. I use the IP addresses 10.1.1.4 and 10.1.1.5
respectively. The two physical ports are connected to two separate LAN
switches which are connected by an uplink. I want to periodically test this
uplink cable. My plan to do this is to send a simple test message (much like
a ping) from 10.1.1.4 to 10.1.1.5, however, the IP stack does not let me do
this. Is there any specific reason why not?
