This is an example of an HTTP server that is accessible via http://esp8266/
|
|
(or perhaps http://esp8266.local/) thanks to the LLMNR responder.
|
|
|
|
Instructions:
|
|
- Update WiFi SSID and password as necessary.
|
|
- Flash the sketch to the ESP8266 board.
|
|
- Windows:
|
|
- No additional software is necessary.
|
|
- Point your browser to http://esp8266/, you should see a response. In most
|
|
cases, it is important that you manually type the "http://" to force the
|
|
browser to search for a hostname to connect to, rather than perform a web
|
|
search.
|
|
- Alternatively, run the following command from the command prompt:
|
|
ping esp8266
|
|
- Linux:
|
|
- To validate LLMNR, install the systemd-resolve utility.
|
|
- Execute the following command:
|
|
systemd-resolve -4 -p llmnr esp8266
|
|
- It may be possible to configure your system to use LLMNR for all name
|
|
lookups. However, that is beyond the scope of this description.
