## DESCRIPTION

avahi-dnsconfd connects to a running avahi-daemon and runs the script */etc/avahi/avahi-dnsconfd.action* for each unicast DNS server that is announced on the local LAN. This is useful for configuring unicast DNS servers in a DHCP-like fashion with mDNS.

  Kill an already running avahi-dnsconfd. (equivalent to sending a SIGTERM)

- **-r \| --refresh**

  Tell an already running avahi-dnsconfd to refresh the DNS server data. (equivalent to sending a SIGHUP)

- **-c \| --check**

  Return 0 as return code when avahi-dnsconfd is already running.

- **-h \| --help**

  Show help

- **-v \| --version**
