116 | * ctrl_interface - Parameters for the control interface | |
117 | * | |
118 | * If this is specified, %wpa_supplicant will open a control interface | |
119 | * that is available for external programs to manage %wpa_supplicant. | |
120 | * The meaning of this string depends on which control interface | |
ffbf1eaa | 121 | * mechanism is used. For all cases, the existence of this parameter |
6fc6879b JM |
122 | * in configuration is used to determine whether the control interface |
123 | * is enabled. | |
124 | * | |
125 | * For UNIX domain sockets (default on Linux and BSD): This is a | |
126 | * directory that will be created for UNIX domain sockets for listening | |
127 | * to requests from external programs (CLI/GUI, etc.) for status | |
128 | * information and configuration. The socket file will be named based | |
129 | * on the interface name, so multiple %wpa_supplicant processes can be | |
130 | * run at the same time if more than one interface is used. | |
131 | * /var/run/wpa_supplicant is the recommended directory for sockets and | |
132 | * by default, wpa_cli will use it when trying to connect with | |
133 | * %wpa_supplicant. | |
134 | * | |
135 | * Access control for the control interface can be configured | |
136 | * by setting the directory to allow only members of a group | |
137 | * to use sockets. This way, it is possible to run | |
138 | * %wpa_supplicant as root (since it needs to change network | |
139 | * configuration and open raw sockets) and still allow GUI/CLI | |
140 | * components to be run as non-root users. However, since the | |
141 | * control interface can be used to change the network | |
142 | * configuration, this access needs to be protected in many | |
143 | * cases. By default, %wpa_supplicant is configured to use gid | |
144 | * 0 (root). If you want to allow non-root users to use the | |
145 | * control interface, add a new group and change this value to | |
146 | * match with that group. Add users that should have control | |
147 | * interface access to this group. | |
148 | * | |
149 | * When configuring both the directory and group, use following format: | |
150 | * DIR=/var/run/wpa_supplicant GROUP=wheel | |
151 | * DIR=/var/run/wpa_supplicant GROUP=0 | |
152 | * (group can be either group name or gid) | |
153 | * | |
154 | * For UDP connections (default on Windows): The value will be ignored. | |
155 | * This variable is just used to select that the control interface is | |
156 | * to be created. The value can be set to, e.g., udp | |
157 | * (ctrl_interface=udp). | |
158 | * | |
159 | * For Windows Named Pipe: This value can be used to set the security | |
160 | * descriptor for controlling access to the control interface. Security | |
161 | * descriptor can be set using Security Descriptor String Format (see | |
162 | * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp). | |
163 | * The descriptor string needs to be prefixed with SDDL=. For example, | |
164 | * ctrl_interface=SDDL=D: would set an empty DACL (which will reject | |
165 | * all connections). | |
