tcpserver will accept connections for any IP by default. To use several
different tcpservers for the same port, you have to tell each where to bind
with the "host" argument. It will use the "first IP address for that host",
so the easiest is to explicitly use the IP address here.
Alias is fine, e.g. eth0:0 for one and eth0:1 for the other. Of course,
they have to be configured appropriately ...
