61 | <para> | |
62 | If the tty service has been configured and is available for the | |
63 | container specified as parameter, this command will launch a | |
be43f17e | 64 | console allowing to log on the container. |
b0a33c1e | 65 | </para> |
66 | ||
67 | <para> | |
68 | The available tty are free slots taken by this command. That | |
69 | means if the container has four ttys available and the command | |
76848789 DE |
70 | has been launched four times each taking a different tty, the |
71 | fifth command will fail because no console will be available. | |
b0a33c1e | 72 | </para> |
73 | ||
74 | <para> | |
75 | The command will connect to a tty. If the connection is lost or | |
76 | broken, the command can be launched again and regain the tty at | |
77 | the state it was before the disconnection. | |
78 | </para> | |
79 | ||

80 | <para> |
81 | A <replaceable>ttynum</replaceable> of 0 may be given to attach | |
82 | to the container's /dev/console instead of its | |
83 | dev/tty<<replaceable>ttynum</replaceable>>. | |
84 | </para> | |

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

105 | This may be given as '^letter' or just 'letter'. For example | |
106 | to use <Ctrl+b q> as the escape sequence use -e '^b'. | |
