If you're on ubuntu, could you go to pad.lv/u/lxc and file a bug so we can better track the configuration info? Otherwise, can you show: uname -r cat /etc/*-release cat /var/lib/lxc/local-server-7/config (*with* the line added) After trying to start the container again the last 200 lines of /va

Depends on how your provider set it up. If it WERE intended to work that way, they would've given you full instructions (e.g. "use this IP, this netmask, and this gateway") instead of just giving the IP (and probably say "add this as a secondary IP on your server). The fact that you say it works

91.143.88.1 actually is the providers gateway for the subnet. The whole IP configuration for the container looks like this: IP address: 91.143.88.119 netmask: 255.255.255.0 broadcast: 91.143.88.255 gateway: 91.143.88.1 So the container is on a totally different subnet, but shouldn't that work a

In your container config you set the IP gateway as: lxc.network.ipv4.gateway=91.143.88.1 But I didn't see that IP addr anywhere else in your email. Where is 88.1 ? Brian ___ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.lin

I'm still confused that is working at the old server, but not at the new one. I wrote an email to my provider asking if they use a kind if MAC filter. I will let you know if this is the solution. Thanks for all your help, Thomas On 11.09.2014 13:08, Tamas Papp wrote: On 09/11/2014 01:06 PM,

Hmm. The old server is also at the same provider and there it is working without a problem (ubuntu 12.04 and lxc 0.7.5). In addition binding the 91.143.88.119 address to the old server in the same way, the setup works without a hassle. Binding the 91.143.88.119 to an aliasing interface (br0:0) o

We face this problem very often. You can try to ping the Host IP and after that the gateway IP from inside the container. If that doesn't work you'll have to send arpings from inside the conainter: arping -I [lxc-interfacename] -U 91.143.88.119 -c4 (arping from iputils package) After that you'll
