Hi.. I have a question about how to view the netmask info in Sun routing
table as shown below? As you can see, there is no netmask info shown. Let
say 192.173.168.0 network, how do I know the netmask is 255.255.255.0 or
255.255.252.0 ? As different netmask represent different hosts range? Linux
one better. What is the different between flags UG and flag U
