My issue is that the Paper UI does not show the correct ARP state.
I have a .things file with:
Thing network:pingdevice:smartphone "Phone (Lou)" [ hostname=“192.168.1.7”, uses_dhcp_listen=1, uses_arp_pings=1, retry=30, timeout=5000, refreshInterval=10000 ]
…where the device referenced is recognized by the network binding in Paper UI. The network binding has ‘allow system pings’ and ‘listen for dhcp requests’ enabled
I have arping installed at /usr/bin/arping, and the path is written the same in the ‘ARP ping tool path’ of the network binding. $PATH includes /usr/bin. However, the ‘arp_state’ of the device shows ‘Disabled’ even though manually pinging the device with the command /usr/bin/arping 192.168.1.7 is successful.
arping -w 5 -c 1 -I eth0 192.168.1.7
also is successful.
Access rights for arping are elevated:
-rwxr-xr-x root root
My network.cfg file matches the settings in Paper UI:
binding.network:allowSystemPings=true binding.network:allowDHCPlisten=true binding.network:arpPingToolPath=/usr/bin/arping binding.network:cacheDeviceStateTimeInMS=2000
I have read several threads on this subject and have run out of ideas. Any steps I am missing?
Full properties in Paper UI for the phone tested are:
|arp_state |Disabled| |---|---| |dhcp_state |Running normally| |icmp_state |IPUTILS_LINUX_PING| |presence_detection_type || |uses_ios_wakeup |Yes|
Channels for the phone are online, latency, and last seen.
