Routing Interview Question:

How to Set a Netmask under SunOS?

Submitted by: Administrator

In order to include a permanent netmask on your SunOS machine, you must make an entry in the /etc/netmasks file, in the following format: network-address-without-zeroes netmask For example: %%%% cat /etc/netmasks 150.101 255.255.255.0 The above would subnet the class B network, 150.101.0.0, into 254 subnets, from 150.101.1.0 to 150.101.254.0. It is important to note that the entry in the left hand column must be the original base network number (ie # for a Class A, #.# for a Class B and #.#.# for a Class C), not the subnet.
