Hi Stephen, After discussing this issue with the Debian maintainer of iproute, I am bringing this issue to you to see if it can be fixed in upstream.
You can see the bug report and discussion at http://bugs.debian.org/726417 Basically, the issue is that there is an inconsistency in the output of "ip addr show" when the -oneline option is used. If the option is not present, ip shows all interfaces, including DOWN ones. When the option is used, these interfaces do not show. This is a regression from previous versions, as the iproute package in Debian Wheezy does not have this behaviour. An example: $ sudo modprobe dummy $ ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000 [..] 3: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000 [..] 10: wwan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 [..] 358: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default link/ether 42:39:cf:86:bb:39 brd ff:ff:ff:ff:ff:ff $ ip -o addr show 1: lo inet 127.0.0.1/8 scope host lo\ valid_lft forever preferred_lft forever 1: lo inet6 ::1/128 scope host \ valid_lft forever preferred_lft forever 10: wwan0 inet XXX/29 brd XXX scope global wwan0\ valid_lft forever preferred_lft forever 10: wwan0 inet6 XXX/64 scope link \ valid_lft forever preferred_lft forever As Andreas (the Debian maintainer) suggested, a simple patch would be to remove the two lines at http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/tree/ip/ipaddress.c#n1179 Thanks for your time.
