Possibly redundant, but if you are connecting these computers via local 
IP only and do not have a router on the LAN, you want each computer to 
have the other's IP address as its own router address.  zum Beispiel:

Computer A:
IP address: 192.168.0.1
Subnet mask: 255.255.255.0
Router address: 192.168.0.2

Computer B:
IP address: 192.168.0.2
Subnet mask: 255.255.255.0
Router address: 192.168.0.1

Normally, the router will have the xx.xx.xx.1 address, and all other 
devices on the network will have addresses between xx.xx.xx.2 and 
xx.xx.xx.254 (xx.xx.xx.255 is reserved for broadcast), but since there 
is no router on this network, each computer has to know that it is 
"routing" through the other computer directly.  This may also explain 
why A is transmitting when you ping and B is not, since the .1 address 
may cause A to assume it is a router for some purposes.  You might get 
more consistent performance by assigning 192.168.0.2 to A and 
192.168.0.3 to B, and changing the router addresses accordingly ..

Heard from a flight instructor:
"The only dumb question is the one you DID NOT ask, resulting in my 
going out and having to identify your bits and pieces in the midst of 
torn and twisted metal."
