lxc-console(1)                                             lxc-console(1)

NAME         top

       lxc-console - Launch a console for the specified container

SYNOPSIS         top

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

DESCRIPTION         top

       If  the  tty  service has been configured and is available for the
       container specified as parameter, this command will launch a  con‐
       sole 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/con‐
       sole 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         top

       -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 au‐
              tomatically chosen by the container.

COMMON OPTIONS         top

       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 ER‐
              ROR. Possible values are : FATAL, ALERT, CRIT, WARN, ERROR,
              NOTICE, INFO, DEBUG, TRACE.

              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 virtualiza‐
              tion 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 previ‐
              ously created container (via lxc-create).

       --version
              Show the version number.

DIAGNOSTIC         top

       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.
