[Lxc-users] can I use lxc-execute to execute an application with network configured

[Sam Wang]

in my computer,wetherip_forward equals 1,it doesn't work.And lxc-execute
ping 10.0.15 does work.the edition of lxc is 0.7.4.2 and the host OS is
centos 6.2 or fedora 16.what'more,I also have tried setting br0 and eth0 in
promisc mode,which is useless.
