NAME¶

lxc-user-nic - Create and attach a nic to another network namespace.

SYNOPSIS¶

lxc-user-nic
{ pid} {type} {bridge} [nicname]

DESCRIPTION¶

lxc-user-nic is a setuid-root program with which unprivileged users may create network interfaces for use by a lxc container. It will consult the configuration file /etc/lxc/lxc-usernet to determine the number of interfaces which the calling user is allowed to create, and which bridge he may attach them to. It tracks the number of interfaces each user has created using the file /run/lxc/nics. It ensures that the calling user is privileged over the network namespace to which the interface will be attached.

OPTIONS¶

pid

The process id for the task to whose network namespace the interface should be attached.

type

The network interface type to attach. Currently only veth is supported. With this type, two interfaces representing each tunnel endpoint are created. One endpoint will be attached to the specified bridge, while the other will be passed into the container.

bridge

The bridge to which to attach the network interface, for instance lxcbr0.

nicname

The desired interface name in the container. This will be eth0 if unspecified.
