How to make virtual interface ping to a host in the network

Question

I created a virtual interface as indicated in this Unix.SE post. I.e.

sudo modprobe dummy
sudo ip link set name eth10 dev dummy0
sudo ifconfig eth10 up
sudo ifconfig eth10 192.168.1.150

I want to send a ping to a host in my network (ping 192.168.1.133), but it does not work.

I tried to add

sysctl -w net.ipv4.conf.eth10.forwarding=1

But that does not work either.

What should I do to make the ping work?

Answer 1

You make mistake

not

sudo ifconfig eth10 192.168.1.150

you must add network mask

sudo ifconfig eth10 192.168.1.150 netmask 255.255.255.0
