[](https://ci.sp-codes.de/samuel-p/connectivity-check) [](#license) [](https://hub.docker.com/r/samuelph/connectivity-check)
|
|
|
|
A self-hosted captive portal connectivity check.
|
|
|
|
## Usage
|
|
|
|
Just run the following command:
|
|
|
|
```bash
|
|
docker run -d -p 80:80 -p 443:443 samuelph/connectivity-check
|
|
```
|
|
|
|
Or with docker-compose:
|
|
|
|
```yaml
|
|
version: '3.4'
|
|
|
|
services:
|
|
connectivitycheck:
|
|
image: samuelph/connectivity-check
|
|
restart: always
|
|
ports:
|
|
- 80:80
|
|
- 443:443
|
|
```
|
|
|
|
## Run on a simple web space
|
|
|
|
Instead of running the docker image you also can just use the following `.htaccess` file on your web server:
|
|
|
|
```
|
|
RewriteEngine On
|
|
|
|
Header always set "X-NetworkManager-Status" "online"
|
|
|
|
RewriteCond "%{REQUEST_FILENAME}" "(generate)?_?204"
|
|
RewriteRule "(generate)?_?204" / [R=204,L]
|
|
|
|
RewriteCond %{HTTPS} off
|
|
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
|
|
```
|
|
|
|
## Setup your devices
|
|
|
|
### Android
|
|
|
|
To change the Captive Portal Check in Android, you need a terminal app or a connection via ADB to a computer.
|
|
|
|
To use `http` you can run the following commands with the respective method:
|
|
|
|
```
|
|
# settings put global captive_portal_use_https 0
|
|
# settings put global captive_portal_http_url "http://connectivitycheck.sp-codes.de/generate204"
|
|
```
|
|
|
|
To use `https` you can use the following two commands:
|
|
|
|
```
|
|
# settings put global captive_portal_use_https 1
|
|
# settings put global captive_portal_https_url "https://connectivitycheck.sp-codes.de/generate204"
|
|
```
|
|
|
|
Maybe you have to reboot your phone after updating the settings.
|
|
|
|
If you are using AFWall+ you need to give access to _[1000] Android-System_ and in some cases _[10040] CaptivePortalLogin_ to make it work.

|
|
|
|
### Ubuntu
|
|
|
|
In Ubuntu, the file `/etc/NetworkManager/NetworkManager.conf` must be changed. Add or change the following lines:
|
|
|
|
```
|
|
[connectivity]
|
|
uri=https://connectivitycheck.sp-codes.de/generate204
|
|
```
|
|
|
|
Restart the network-manager:
|
|
|
|
```
|
|
sudo service network-manager restart
|
|
```
|
|
|
|
For more information see [here](https://askubuntu.com/q/1167177/920103).
|
|
|
|
### Firefox
|
|
|
|
Type [about:config](about:config) in the Firefox address bar and search for `captivedetect.canonicalURL` and `network.connectivity-service`. Set the URL values to `https://connectivitycheck.sp-codes.de/generate204`, the domain values to `connectivitycheck.sp-codes.de`. That's it.
