lxc-console(1)

NAME

   lxc-console - Launch a console for the specified container

SYNOPSIS

   lxc-console {-n name} [-e escape character] [-t ttynum]

DESCRIPTION

   If  the  tty  service  has  been  configured  and  is available for the
   container specified as parameter, this command will  launch  a  console
   allowing to log on the container.

   The  available  tty are free slots taken by this command. That means if
   the container has four ttys available and the command has been launched
   four  times  each  taking  a different tty, the fifth command will fail
   because no console will be available.

   The command will connect to a tty. If the connection is lost or broken,
   the  command  can  be launched again and regain the tty at the state it
   was before the disconnection.

   A ttynum of 0 may be given to attach to  the  container's  /dev/console
   instead of its dev/tty<ttynum>.

   A  keyboard  escape sequence may be used to disconnect from the tty and
   quit lxc-console. The default escape sequence is <Ctrl+a q>.

OPTIONS

   -e, --escape escape character
          Specify the escape sequence prefix to use instead of  <Ctrl  a>.
          This  may be given as '^letter' or just 'letter'. For example to
          use <Ctrl+b q> as the escape sequence use -e '^b'.

   -t, --tty ttynum
          Specify the tty number to connect to or 0 for  the  console.  If
          not   specified   the   next   available   tty  number  will  be
          automatically chosen by the container.

COMMON OPTIONS

   These options are common to most of lxc commands.

   -?, -h, --help
          Print a longer usage message than normal.

   --usage
          Give the usage message

   -q, --quiet
          mute on

   -P, --lxcpath=PATH
          Use an alternate container path. The default is /var/lib/lxc.

   -o, --logfile=FILE
          Output to an alternate log FILE. The default is no log.

   -l, --logpriority=LEVEL
          Set log priority to LEVEL. The default log  priority  is  ERROR.
          Possible  values  are  : FATAL, CRIT, WARN, ERROR, NOTICE, INFO,
          DEBUG.

          Note that this option is setting the priority of the events  log
          in  the  alternate  log file. It do not have effect on the ERROR
          events log on stderr.

   -n, --name=NAME
          Use container identifier NAME.  The container identifier  format
          is an alphanumeric string.

   --rcfile=FILE
          Specify  the  configuration file to configure the virtualization
          and isolation functionalities for the container.

          This configuration file if present will be used even if there is
          already  a  configuration file present in the previously created
          container (via lxc-create).

   --version
          Show the version number.

DIAGNOSTIC

   tty service denied
          No tty is available or there is not enough privilege to use  the
          console.  For  example,  the container belongs to user "foo" and
          "bar" is trying to open a console to it.
