Hey everyone,
I've been trying to configure Ubuntu LXC with 2 ip failover from OVH
but i failed :(
I've been reading many howto's and still nothing. I have found on this
list same cool tutorial which has written by Olivier. There is a link:
https://lists.linuxcontainers.org/pipermail/lxc-users/2011-May/001980.html
I don't know why i still can't get access to internet from LXC.
My host ip: 94.23.237.216
My ip fail over ip 1: 91.121.239.228
I'll focus on one failover ip.
I did as Olivier has subscribed.
Host:
root@ns321124:~# cat /etc/network/interface
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
auto br0
iface br0 inet static
bridge_ports eth0
bridge_stp off
bridge_maxwait 0
bridge_fd 0
address 94.23.237.216
netmask 255.255.255.0
network 94.23.237.0
broadcast 94.23.237.255
gateway 94.23.237.254
post-up /sbin/ifconfig br0:0 91.121.239.228 netmask 255.255.255.255
broadcast 91.121.239.228
post-down /sbin/ifconfig br0:0 down
Use either post-up and /sbin/ip or 'iface br0:0 inet static.....'.
root@ns321124:~# cat /var/lib/lxc/Oksymoron/config
# Template used to create this container:
/usr/share/lxc/templates/lxc-ubuntu
# Parameters passed to the template:
# For additional config options, please look at lxc.container.conf(5)
# Common configuration
lxc.include = /usr/share/lxc/config/ubuntu.common.conf
# Container specific configuration
lxc.rootfs = /var/lib/lxc/Oksymoron/rootfs
lxc.mount = /var/lib/lxc/Oksymoron/fstab
lxc.utsname = Oksymoron
lxc.arch = amd64
# Network configuration
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name <http://lxc.network.name> = eth0
lxc.network.ipv4 = 91.121.239.228
Use this IP either here or on the bridge iface, but not at both places.
root@ns321124:~# cat /var/lib/lxc/Oksymoron/rootfs/etc/network/interfaces
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
adress 91.121.239.228
netmask 255.255.255.255
broadcast 91.121.239.228
Define your network either in container:/etc/network/interfaces or in
lxc config file, but not at both places.
post-up route add 94.23.237.254 dev eth0
post-up route add default gw 94.23.237.254
post-down route del 94.23.237.254 dev eth0
post-down route del default gw 94.23.237.254
Why not the standard 'gateway .....' configuration?
For sure i did reboot and lunch lxc.
Checking ifconfig in LXC called Oksymoron
