http://unix.stackexchange.com – On debian squeeze, I setup a bridge based on eth0. My /etc/network/interfaces is # The loopback network interface auto lo iface lo inet loopback # The primary network interface #allow-hotplug eth1 #auto eth0 iface eth0 inet manual iface eth0 inet6 manual auto br0 iface br0 inet dhcp bridge_ports eth0 bridge_stp off # bridge_maxwait 0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 Despite setting eth0 to manual, it get's an ip address via DHCP. Setting ifconfig eth0 down explicitly, disables the interface for a few seconds before it comes back up again. How c (HowTos)

Stories similar to eth0 not getting disabled after setting up br0 interface

I have debian hosts which are connected through trunk port on 5 different vlans. But this host respond to arp "who-has" requests of all of their differents ip.

Bridged networking in KVM 51 weeks 5 days ago

I'm using ubuntu 10.04 with qemu-kvm installed. I bridged my eth0 to br0. My problem is that The host OS loses connection. Here is my interfaces file

auto lo iface lo inet loopback

auto eth0 iface eth0 inet manual

auto br0 iface br0 inet dhcp bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0

I can't ifdown an interface on a Debian 6.0.5 box;

user@box:/etc/network$ sudo ifdown eth0 && sudo ifup eth0 ifdown: interface eth0 not configured SIOCADDRT: File exists Failed to bring up eth0.

user@box:/etc/network$ cat interfaces auto lo iface lo inet loopback

allow-hotplug eth0 allow-hotplug eth1

auto eth0 iface eth0 inet static address 10.0.0.1 netmask 255.255.255.0 gateway 10.

I want to use my desktop with a wired ethernet connection (eth0) to operate my USB Wifi Adapter (wlan0) as a non-adhoc access point (so my android can connect to it).

After MUCH searching, I finally found a method that works with about 95% of what I want.

I modified "/etc/network/interfaces" to contain:

auto lo iface lo inet loopback

auto eth0 iface eth0 inet manual

auto br0 iface br0 i

I have an EC2 instance running inside a VPC.

The IP does no longer respond to a remote ping

With restart I mean:

lxc-stop -n vm3 lxc-start -n vm3 -f /etc/lxc/vm3.conf -d

--

/etc/network/interfaces

auto lo iface lo inet loopback up route add -net 127.0.0.0 netmask 255.0.0.0 dev lo down route add -net 127.0.0.0 netmask 255.0.0.0 dev lo

# device: eth0 auto eth0 iface eth0 inet manual

auto br0 iface br0 inet static address 192.22

Debian Squeeze as a router 45 weeks 3 days ago

I'm trying to setup Debian Squeeze (ala Dreamplug) as a router.

I'm wondering if I've found a bug in ifupdown, but I wanted to ask here before reporting a bug:

/etc/network/if-up.d/upstart seems to fail to emit static-network-up if any virtual interfaces are defined.
