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 in‐
terfaces for use by a lxc container.
It will consult the configuration file /etc/lxc/lxc-usernet to determine the number of in‐
terfaces 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 in‐
terface will be attached.
OPTIONS
pid The process id for the task to whose network namespace the interface should be at‐
tached.
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.
