[Lxc-users] Problem with lxc and mutliple ips
Dear list, we are using lxc 0.8 on Debian Wheezy (official debian package). Now we wanted to start a lxc with more than one IP address and we have gotten strange behaviors. As starting the lxc some IPs are reachable, some not. If we shut down the lxc and boot again, some other IPs are reachable. There seams no logic behind this. And - in no time - there were all IPs reachable. If we are using only one IP for LXC, all is fine. Do someone else have gotten this problem? All help and ideas are appreciated.

Dear Andreas, please substantiate your term start a lxc with multiple IPs and the line If we are using only one IP for LXC, all is fine: What kind of network setup do you use, is it e.g. a bridge on the lxc host and veth's on the containers? A guess might be that you have a MAC address clash; did you override the lxc.network.hwaddr?

Re: [Lxc-users] Problem with lxc and mutliple ips
Ok, sorry. You're right. We are using a bridge named br0 bound to eth0 at lxc host. On the containers we are using veth, but this problem happens also with type macvlan. No change at all. We also tried using hwaddr. We're doing further research in hope to show a way to reproduce this for you.

Re: [Lxc-users] Problem with lxc and mutliple ips
Dear Andreas, Thank you for the first clarification. But now I want to ask what exactly is not working: * Are you trying to use more than one Containers with one IP or one Container with more than one IP? * Are you using the same subnets? * From what location you can't reach the IP, did this station list the right MAC in it's ARP table at least? * Can you reach the LXC host from there? Can you reach others from the Host? Can you reach the host or others from the Containers? * Has your host an IP (on the bridge)? Is STP enabled, is the forward delay and hello time at an appropriate low value? * Is the Host connected to a Switched Network? What did you observe here with respect to the used MACs / IPs?

Re: [Lxc-users] Problem with lxc and mutliple ips
Hi, actually can't get lxc nightly compiled with debian right now, configure has problems with pkg-config python3-dev (package pkg-config and python3-dev is installed) (configure line 5588) I tried instead lxc 0.9 from tarball and got the same problem. Our LXC Config is attached, maybe this helps. Our lxc-host bridge is configured like auto br0 iface br0 inet static bridge_ports eth4 bridge_stp off address 10.5.255.80 netmask 255.255.0.0 gateway 10.5.255.252 Andreas Am 11.10.2013 10:45, schrieb Tamas Papp: On 10/11/2013 10:40 AM, Andreas Laut wrote: Ok, sorry.
