Tried again today, in Ubuntu 10.04 with all the updates applied, and the bug is still there.
To Stéphane Graber (stgraber) and Daniel Hahler (blueyed), here are the outputs of the commands when both eth0 and eth1 are "up" and the networking doesn't work: ---------------------------------------------- root@pc1:/# ip link show 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: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ether 00:18:f3:91:08:9d brd ff:ff:ff:ff:ff:ff 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:18:f3:91:11:eb brd ff:ff:ff:ff:ff:ff 4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000 link/ether 00:15:af:08:f6:ea brd ff:ff:ff:ff:ff:ff ---------------------------------------------- root@pc1:/# ip addr show 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 UNKNOWN qlen 1000 link/ether 00:18:f3:91:08:9d brd ff:ff:ff:ff:ff:ff inet 192.168.1.2/24 brd 192.168.1.255 scope global eth0 inet6 fe80::218:f3ff:fe91:89d/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:18:f3:91:11:eb brd ff:ff:ff:ff:ff:ff inet 192.168.1.3/24 brd 192.168.1.255 scope global eth1 inet6 fe80::218:f3ff:fe91:11eb/64 scope link valid_lft forever preferred_lft forever 4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000 link/ether 00:15:af:08:f6:ea brd ff:ff:ff:ff:ff:ff ---------------------------------------------- root@pc1:/# ip route show 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.2 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.3 169.254.0.0/16 dev eth1 scope link metric 1000 default via 192.168.1.1 dev eth1 metric 100 default via 192.168.1.1 dev eth0 metric 100 ---------------------------------------------- root@pc1:/# ip route get 1.2.3.4 1.2.3.4 via 192.168.1.1 dev eth0 src 192.168.1.2 cache mtu 1500 advmss 1460 hoplimit 64 ---------------------------------------------- root@pc1:/# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 192.168.1.0 * 255.255.255.0 U 0 0 0 eth1 link-local * 255.255.0.0 U 1000 0 0 eth1 default 192.168.1.1 0.0.0.0 UG 100 0 0 eth1 default 192.168.1.1 0.0.0.0 UG 100 0 0 eth0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/788301 Title: Networking fails with two interfaces on the same network To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/788301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
