258 | * If this is specified, %wpa_supplicant will open a control interface | |
259 | * that is available for external programs to manage %wpa_supplicant. | |
260 | * The meaning of this string depends on which control interface | |
ffbf1eaa | 261 | * mechanism is used. For all cases, the existence of this parameter |
6fc6879b JM |
262 | * in configuration is used to determine whether the control interface |
263 | * is enabled. | |
264 | * | |
265 | * For UNIX domain sockets (default on Linux and BSD): This is a | |
266 | * directory that will be created for UNIX domain sockets for listening | |
267 | * to requests from external programs (CLI/GUI, etc.) for status | |
268 | * information and configuration. The socket file will be named based | |
269 | * on the interface name, so multiple %wpa_supplicant processes can be | |
270 | * run at the same time if more than one interface is used. | |
271 | * /var/run/wpa_supplicant is the recommended directory for sockets and | |
272 | * by default, wpa_cli will use it when trying to connect with | |
273 | * %wpa_supplicant. | |
274 | * | |
275 | * Access control for the control interface can be configured | |
276 | * by setting the directory to allow only members of a group | |
277 | * to use sockets. This way, it is possible to run | |
278 | * %wpa_supplicant as root (since it needs to change network | |
279 | * configuration and open raw sockets) and still allow GUI/CLI | |
280 | * components to be run as non-root users. However, since the | |
281 | * control interface can be used to change the network | |
282 | * configuration, this access needs to be protected in many | |
283 | * cases. By default, %wpa_supplicant is configured to use gid | |
284 | * 0 (root). If you want to allow non-root users to use the | |
285 | * control interface, add a new group and change this value to | |
286 | * match with that group. Add users that should have control | |
287 | * interface access to this group. | |
288 | * | |
289 | * When configuring both the directory and group, use following format: | |
290 | * DIR=/var/run/wpa_supplicant GROUP=wheel | |
291 | * DIR=/var/run/wpa_supplicant GROUP=0 | |
292 | * (group can be either group name or gid) | |
293 | * | |
294 | * For UDP connections (default on Windows): The value will be ignored. | |
295 | * This variable is just used to select that the control interface is | |
296 | * to be created. The value can be set to, e.g., udp | |
297 | * (ctrl_interface=udp). | |
298 | * | |
299 | * For Windows Named Pipe: This value can be used to set the security | |
300 | * descriptor for controlling access to the control interface. Security | |
301 | * descriptor can be set using Security Descriptor String Format (see | |
302 | * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp). | |
303 | * The descriptor string needs to be prefixed with SDDL=. For example, | |
