How can I create a virtual interface similar to the following
$ sudo ifconfig eth1 hw ether 00:01:02:aa:bb:cc SIOCSIFHWADDR: No such device
This does not work. I want to set the MAC addresses to test my DHCP server's configuration.
How would I do that with the
iproute2 suite using the ip link command?
$ sudo ip link add type veth
This works, but it randomly assigns a MAC address. This is still useful, but I would like to test my
dhcpd server with some specific MAC addresses in order to see how it handles the classes I have set up.
My current setup:
$ ip ad 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 60:eb:69:1b:a0:88 brd ff:ff:ff:ff:ff:ff inet 172.16.0.93/24 brd 172.16.0.255 scope global eth0 inet6 fe80::62eb:69ff:fe1b:a088/64 scope link valid_lft forever preferred_lft forever 7: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 0a:00:27:00:00:00 brd ff:ff:ff:ff:ff:ff 8: veth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 3a:50:38:2e:24:c4 brd ff:ff:ff:ff:ff:ff
