wpa_supplicant

The new wpa_supplicant packages have removed the /etc/wpa_supplicant.conf file. Wireless LAN is now configured via special commands from /etc/network/interfaces, which looks like an elegant Debian way to do things.

While setting this up, I have learned the following:

  • an ESSID starting with "+" is not accepted
  • You don't enter the passphrase verbatim into /e/n/i, you use wpa_passphrase to hash it
  • wpa_supplicant debugs surprisingly well

Well done, maintainers! Thanks!

Next time I'll figure out how to configure wpa_supplicant to automatically associate to the correct wireless LAN regardless of location
