NAME

6       lxc-console - Launch a console for the specified container
7

SYNOPSIS

9       lxc-console {-n name} [-e escape character] [-t ttynum]
10

DESCRIPTION

12       If  the  tty  service has been configured and is available for the con‐
13       tainer specified as parameter, this command will launch a  console  al‐
14       lowing to log on the container.
15
16       The  available  tty are free slots taken by this command. That means if
17       the container has four ttys available and the command has been launched
18       four times each taking a different tty, the fifth command will fail be‐
19       cause no console will be available.
20
21       The command will connect to a tty. If the connection is lost or broken,
22       the  command  can  be launched again and regain the tty at the state it
23       was before the disconnection.
24
25       A ttynum of 0 may be given to attach to  the  container's  /dev/console
26       instead of its dev/tty<ttynum>.
27
28       A  keyboard  escape sequence may be used to disconnect from the tty and
29       quit lxc-console. The default escape sequence is <Ctrl+a q>.
30

OPTIONS

32       -e, --escape escape character
33              Specify the escape sequence prefix to use instead of  <Ctrl  a>.
34              This  may be given as '^letter' or just 'letter'. For example to
35              use <Ctrl+b q> as the escape sequence use -e '^b'.
36
37       -t, --tty ttynum
38              Specify the tty number to connect to or 0 for  the  console.  If
39              not specified the next available tty number will be automatical‐
40              ly chosen by the container.

DIAGNOSTIC

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