Hi folks,
I have a strange bahaviour using connman 1.20
I have a device with an ethernet card and a wifi card
Both card are with dhcp and are connected to the same network (I know
this is not good, but I can't do in a different way). Furthermore the
ethernet card got a static IP on a different subnet
So my routing table looks like this
root@razor:~# ip route
192.168.10.100 via 192.168.10.100 dev eth0
192.168.10.100 dev eth0 scope link
192.168.10.100 dev wlan0 scope link metric 10
10.189.189.0/24 dev eth0 proto kernel scope link src 10.189.189.1
192.168.10.0/24 dev eth0 proto kernel scope link src 192.168.10.109
192.168.10.0/24 dev wlan0 proto kernel scope link src 192.168.10.107
metric 10
224.0.0.0/24 dev eth0 scope link
default via 192.168.10.100 dev eth0
192.168.10.100 is the dhcp server / default gateway (simply a wireless
router); 10.189.189.0/24 is a control subnet used to reach other devives
through a switch (no VLAN)
You can see that the route via eth0 is preferred because of a lower metric
root@razor:~# ip route get 192.168.10.100
192.168.10.100 dev eth0 src 192.168.10.109
cache ipid 0x34b2 mtu 1500 advmss 1460 hoplimit 64
The problem arise when I disconnect the ethernet cable, because the
routing table doesn't change at all and if I check the previous route I
obtain
root@razor:~# ip route get 192.168.10.100
192.168.10.100 dev eth0 src 10.189.189.1
cache mtu 1500 advmss 1460 hoplimit 64
So the route goes via eth0, using the static configured ip
The interface looks like this
root@razor:~# ip link
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
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,DYNAMIC,UP> mtu 1500 qdisc
pfifo_fast state DOWN qlen 1000
link/ether 00:21:84:30:03:78 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP
qlen 1000
link/ether 00:21:84:26:01:84 brd ff:ff:ff:ff:ff:ff
Is this the expected behaviour under these conditions?
Why routes through eth0 (which is down) aren't removed from routing table?
Thanks you all
G
