have you tried to ping the ip from another machine? or are you doing it from the same machine with all of the interfaces? if you are trying to ping from the machine(with the network interface) than what will happen is the interface will send out an arp request to the network trying to get the interface's MAC address. interfaces are not allowed to send out and recieve packets to itself... that is what loopback is for. so you need to let the machine know that it owns the interface. you can do this by manipulating the arp table. arp -a... should show all entries in the table. francis (10.0.17.150) at 0:b0:99:99:99:0 permanent [ethernet] if the alias address is 10.0.17.151 what you need to do is arp -s 10.0.17.151 0:b0:99:99:99:0 once the alias address is in the arp table you should be able to ping from the host machine.
