Hello folks,
just a quick follow up that... I hit a PEBKAC by observing the output
of ping(8). The various nodes actually communicates.

I have tried on "abacus" (10.2.0.3):

 abacus$ nc -l 8080

...and then on "boh" (10.2.0.4):

 boh$ socat - TCP-CONNECT:10.2.0.3:8080
 foo
 bar
 baz
 ^D

...and then on "abacus" (10.2.0.3) I can see:

 foo
 bar
 baz

So it works!


Sorry for the noise and thanks for several pointers that I've got in
private!
