lxc-user-nic(1)

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.
