185 | * | |
186 | * If this is specified, %wpa_supplicant will open a control interface | |
187 | * that is available for external programs to manage %wpa_supplicant. | |
188 | * The meaning of this string depends on which control interface | |
ffbf1eaa | 189 | * mechanism is used. For all cases, the existence of this parameter |
6fc6879b JM |
190 | * in configuration is used to determine whether the control interface |
191 | * is enabled. | |
192 | * | |
193 | * For UNIX domain sockets (default on Linux and BSD): This is a | |
194 | * directory that will be created for UNIX domain sockets for listening | |
195 | * to requests from external programs (CLI/GUI, etc.) for status | |
196 | * information and configuration. The socket file will be named based | |
197 | * on the interface name, so multiple %wpa_supplicant processes can be | |
198 | * run at the same time if more than one interface is used. | |
199 | * /var/run/wpa_supplicant is the recommended directory for sockets and | |
200 | * by default, wpa_cli will use it when trying to connect with | |
201 | * %wpa_supplicant. | |
202 | * | |
203 | * Access control for the control interface can be configured | |
204 | * by setting the directory to allow only members of a group | |
205 | * to use sockets. This way, it is possible to run | |
206 | * %wpa_supplicant as root (since it needs to change network | |
207 | * configuration and open raw sockets) and still allow GUI/CLI | |
208 | * components to be run as non-root users. However, since the | |
209 | * control interface can be used to change the network | |
210 | * configuration, this access needs to be protected in many | |
211 | * cases. By default, %wpa_supplicant is configured to use gid | |
212 | * 0 (root). If you want to allow non-root users to use the | |
213 | * control interface, add a new group and change this value to | |
214 | * match with that group. Add users that should have control | |
215 | * interface access to this group. | |
216 | * | |
217 | * When configuring both the directory and group, use following format: | |
218 | * DIR=/var/run/wpa_supplicant GROUP=wheel | |
219 | * DIR=/var/run/wpa_supplicant GROUP=0 | |
220 | * (group can be either group name or gid) | |
221 | * | |
222 | * For UDP connections (default on Windows): The value will be ignored. | |
223 | * This variable is just used to select that the control interface is | |
224 | * to be created. The value can be set to, e.g., udp | |
225 | * (ctrl_interface=udp). | |
226 | * | |
227 | * For Windows Named Pipe: This value can be used to set the security | |
228 | * descriptor for controlling access to the control interface. Security | |
229 | * descriptor can be set using Security Descriptor String Format (see | |
230 | * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp). | |
231 | * The descriptor string needs to be prefixed with SDDL=. For example, | |
232 | * ctrl_interface=SDDL=D: would set an empty DACL (which will reject | |
233 | * all connections). | |
