Sun systems only support netmasks for networks that are directly connected to a machine. This means that if you try and add a netmask for a network that is not directly connected to your machine, it will fail. If you want to route to a remote network which is subnetted, the correct method is to route to a machine that is directly connected to the subnetted network, and then allow that machine to route to the appropriate subnetwork. When RFC 1219 is implemented on Suns, this functionality may become available. QUESTION: How do I make SunOS 4.x limited broadcast all 1’s like solaris2. ANSWER: Manually specify the broadcast, ——— example: # ifconfig le0 flags=63 inet 1207.48.123.87 netmask ffffff00 broadcast 207.48.123.0 ether 8:0:20:1a:f:83 # ifconfig le0 broadcast 129.151.21.255 # ifconfig le0 flags=63 inet 207.48.123.87 netmask ffffff00 broadcast 207.48.123.255 ether 8:0:20:1a:f:83 ——— Add a ifconfig line to /
