NOTE: I'm not looking at using the lo
loopback network interface.
We're developing an embedded device that has its own internal Ethernet network, and a second network that is exposed to the outside world. The plan is to use SSH to tunnel through and access services on that internal network.
Does software exist that has a server part that simply accepts a connection and echoes everything back to the client, and a client part that simply crams data into the pipe and watches it come back, reporting on throughput, or at least simply loading the system so we can see what effect it has?
I had some difficulty searching the 'net for this, since "loopback" nearly always talks about the lo
interface. I could implement myself, but if something already exists...
