Getting started

After compiling and installing Apfree WiFiDog into your local router, run the ps | grep wifidog command. The ps | grep wifidog command queries the linux system for information about Apfree WiFiDog.

root@lede:~# ps | grep wifidog
 1406 root      6532 S    /usr/bin/wifidog -c /tmp/wifidog.conf -f -d 0

• Using operations of -c -f -d for default parameters, and you can get their by running command wifidog --help.
