489 * If this is specified, %wpa_supplicant will open a control interface
490 * that is available for external programs to manage %wpa_supplicant.
491 * The meaning of this string depends on which control interface
Dmitry Shmidt1f69aa52012-01-24 16:10:04 -0800492 * mechanism is used. For all cases, the existence of this parameter
Dmitry Shmidt8d520ff2011-05-09 14:06:53 -0700493 * in configuration is used to determine whether the control interface
494 * is enabled.
495 *
496 * For UNIX domain sockets (default on Linux and BSD): This is a
497 * directory that will be created for UNIX domain sockets for listening
498 * to requests from external programs (CLI/GUI, etc.) for status
499 * information and configuration. The socket file will be named based
500 * on the interface name, so multiple %wpa_supplicant processes can be
501 * run at the same time if more than one interface is used.
502 * /var/run/wpa_supplicant is the recommended directory for sockets and
503 * by default, wpa_cli will use it when trying to connect with
504 * %wpa_supplicant.
505 *
506 * Access control for the control interface can be configured
507 * by setting the directory to allow only members of a group
508 * to use sockets. This way, it is possible to run
509 * %wpa_supplicant as root (since it needs to change network
510 * configuration and open raw sockets) and still allow GUI/CLI
511 * components to be run as non-root users. However, since the
512 * control interface can be used to change the network
513 * configuration, this access needs to be protected in many
514 * cases. By default, %wpa_supplicant is configured to use gid
515 * 0 (root). If you want to allow non-root users to use the
516 * control interface, add a new group and change this value to
517 * match with that group. Add users that should have control
518 * interface access to this group.
519 *
520 * When configuring both the directory and group, use following format:
521 * DIR=/var/run/wpa_supplicant GROUP=wheel
522 * DIR=/var/run/wpa_supplicant GROUP=0
523 * (group can be either group name or gid)

527 * to be created. The value can be set to, e.g., udp
528 * (ctrl_interface=udp).
529 *
530 * For Windows Named Pipe: This value can be used to set the security
531 * descriptor for controlling access to the control interface. Security
532 * descriptor can be set using Security Descriptor String Format (see
533 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
