[Lxc-users] Broken pipe when ssh from host to container

[Verdi March]

Hi Serge,

here's the requested information.

Quoting Serge Hallyn <serge.hallyn at canonical.com>:
> What does br0's config look like?  Can you show us /etc/network/interfaces

=======================================
verdi.march at opencirrus-07308:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp
=======================================

FYI, the br0 was setup from the command line, hence you don't see it in
the /etc/network/interfaces.

Here're the commands I used to setup the bridge, based on instructions
in https://www.ibm.com/developerworks/linux/library/l-lxc-containers/

brctl addbr br0
brctl setfd br0 0
ifconfig br0 198.55.32.143 promisc up
brctl addif br0 eth0
ifconfig eth0 0.0.0.0 up

The IP address is the same as what's allocated by DHCP to the eth0.
