@Bryn, how is the ROUTER (i.e. 94.23.237.254) setup? Is it configured
to route the additional IP (91.121.239.228) thru host's IP
(94.23.237.216), the way some dedicated server provider does (e.g.
serverloft)?
If yes, then the EASY way would be to put 91.121.239.228 as an alias
in host's interface (I'd just use eth0, no need to use a bridge there)
and setup a static NAT to whatever IP the container has (e.g.
10.0.3.251, connected to host's lxcbr0 bridge)
Hey,
It's server dedicated in OVH.
Then ask OVH how to use that IP.
I have one ip like 94.23.237.216 and i bought one more called "ip failover"
like 91.121.239.228. You say as an alias and setup static NAT. But what
about 2 ip failover ?
If my guess is right, it's similar to serverloft. They will say
"simply put it as an IP alias/additional IP on your server".
As in, the additional IP is routed to ONE of your server's IP.
Permanently. Can't be used on other server. Thus, there can be NO
failover.
It's not a standard failover setup where two or more physical servers
each have an IP in the same network segment, and you can have one or
more virtual IP for your services that can fail over to any of the
servers.
I had a server on FreeBSD-10 before and i had 2 jails with 1 failover ip per
jail, work well.
To prevent confusion and wasting everyone's time, what do you mean by
"failover IP"?
That simply looks like addtional IP (i.e. you only have one server),
not an IP that can be failed over between two physical servers.
OVH says :
post-up /sbin/ifconfig eth0:X IP.FAIL.OVER netmask 255.255.255.255 broadcast
IP.FAIL.OVER
post-down /sbin/ifconfig eth0:X down
Or as bridge:
/etc/network/interfaces
auto lo eth0
iface lo inet loopback
iface eth0 inet static
address IP.FAIL.OVER
netmask 255.255.255.255
broadcast IP.FAIL.OVER
post-up route add IP..SERWERA.254 dev eth0
post-up route add default gw IP.SERWERA.254
post-down route del IP..SERWERA.254 dev eth0
post-down route del default gw IP.SERWERA.254
If that snippet work, you can use it as the container's
/etc/network/interfaces. ONLY put the additional IP there. Do NOT put
the ip address in the host's bridge.
Ehhhh This LXC doesn't work. I don't know what to do. Don't know how to
add secondary ip to lxc.
There are settings by default after install dedicated server (ubuntu 14.04):

I created first lxc by lxc-create -t ubuntu -n Oksymoron and works fine.
And now i want to add additional ip which i bought - 91.121.239.228
I tried fast add alias /sbin/ifconfig eth0:X IP.FAIL.OVER netmask
255.255.255.255 broadcast IP.FAIL.OVER
In my case:
sbin/ifconfig eth0:0 91.121.239.228 netmask 255.255.255.255 broadcast
91.121.239.228
I tried ping and connet by ssh and works perfect.
eth0:0 Link encap:Ethernet HWaddr 00:30:48:bd:ee:08
inet addr:91.121.239.228 Bcast:91.121.239.228
Mask:255.255.255.255
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Interrupt:16 Memory:fbce0000-fbd00000
But still don't know how to add or redirect "ip" to lxc called
Oksymoron. Nothing ways work.
I lost faith that it will work.
