I will sketch what we had:
-----------------
router to the university
-----------------
|
switch-----------building A switch
|
And on other ports many other computers in Building B
Well, this is just a little sketch. The network file:
NETMASK=255.255.254.0
NETWORK=152.66.236.0
BROADCAST=152.66.237.255
GATEWAY=152.66.237.254
ifconfig eth0 ${IPADDR} netmask ${NETMASK} broadcast ${BROADCAST}
So we didn't need another router, only one to communicate to the university
and to the outer world (that wasn't even in the dorm, we could just see an
optival wire coming from there), otherwise we could just use both C subnets,
with simple switching.
