62 | <para> | |
63 | <command>lxc-user-nic</command> is a setuid-root program with which | |
64 | unprivileged users may create network interfaces for use by a lxc container. | |
65 | </para> | |
66 | <para> | |
67 | It will consult the configuration file <filename>@LXC_USERNIC_CONF@</filename> | |
e43157b4 | 68 | to determine the number of interfaces which the calling user is allowed to |
df3415e0 SH |
69 | create, and which bridge he may attach them to. It tracks the |
70 | number of interfaces each user has created using the file | |
71 | <filename>@LXC_USERNIC_DB@</filename>. It ensures that the calling | |
72 | user is privileged over the network namespace to which the interface | |
73 | will be attached. | |
