hostapd:tldr:ec6c8
The command "sudo hostapd -B ${path-to-hostapd-conf}" is used to start the hostapd daemon with a specific configuration file.
Here is the breakdown of the command:
-
"sudo" is a command used in Unix-like operating systems to run a command with administrative privileges or as the root user. It requests elevated privileges to execute the subsequent command.
-
"hostapd" is a user space daemon for access point and authentication servers. It allows you to turn your computer into a WiFi access point and manage various aspects of wireless connectivity.
-
"-B" is an option flag that tells hostapd to run in the background as a daemon. This allows it to start running and continue execution without blocking the terminal.
-
"${path-to-hostapd-conf}" is a placeholder indicating that you should replace it with the actual path to the hostapd configuration file. The configuration file contains various settings and parameters that define the behavior of the access point, such as the SSID, authentication method, encryption, and more.
By running this command, hostapd will start as a background process using the specified configuration file. It will then create a WiFi access point according to the settings defined in the configuration file.
