Public bug reported:
I have noticed a possible regression in ifconfig. When executing #
ifconfig , only parent network interfaces are output. ifconfig is
failing to display child/sub interfaces (aka. secondary interfaces.)
Also, running "# ifconfig -a" doesn't display the child/sub-interfaces.
Although the secondary IP is bound to the parent interface, and
functional. The child/sub-interface IP addresses *can* be properly seen
on eth0 when using iproute, by running "# ip addr", as expected.
The /etc/network/interfaces file specifies two eth0 interfaces and
addresses. Example: (lo entry omitted)
auto eth0
iface eth0 inet static
address 10.10.10.10
netmask 255.255.255.0
broadcast 10.10.10.255
gateway 10.10.10.1
auto eth0:2
iface eth0:2 inet static
address 10.10.10.11
netmask 255.255.255.0
-------------------------
I have observed this on two separate Oneiric-servers, v11.10.
