# Introduction |
|
|
|
This is a short text to introduce you about an OpenBSD feature arrived |
|
in 2018 and that may not be known by everyone. Wifi interfaces can |
|
have a list of network and their associated passphrase to automatically |
|
connect when network is known. |

# How to configure |
|
|
|
The relevant configuration information is in the ifconfig man page, |
|
look for "WIRELESS DEVICES" and check the "join" keyword. |

|
Basically, in your /etc/hostname.if file (if being replaced by the |
|
interface name like iwm0, athn0 etc...), list every access point you |
|
know and their according password. |
|
|
|
```configuration sample |
|
join android_hotspot wpakey t00345Y4Y0U |
|
join my-home wpakey goodbyekitty |
|
join friends1 wpakey ilikeb33r5 |
|
join favorite-bar-hotspot |
|
``` |
|
|
|
This will make the wifi interface to try to connect to the first |
|
declared network in the file if multiples access points are available. |
|
You can temporarily remove a hotspot from the list using "ifconfig iwm0 |
|
-join android_hotspot" if you don't want to connect to it. |
