I am trying to ping a Moxa using a BeagleBone Black, but I keep getting " Network is unreachable"
Here is how my ifconfig looks :

and here is how my interfaces look :
This file describes the network interfaces available on your system
and how to activate them. For more information, see interfaces(5).
The loopback network interface
auto lo
iface lo inet loopback
The primary network interface
#allow-hotplug eth0
#auto eth0
#iface eth0 inet dhcp
Example to keep MAC address between reboots
#hwaddress ether DE:AD:BE:EF:CA:FE
iface eth0 inet static
address 192.168.5.21
netmask 255.255.255.0
The secondary network interface
#allow-hotplug eth1
#iface eth1 inet dhcp
WiFi Example
#auto wlan0
#iface wlan0 inet dhcp
wpa-ssid “essid”
wpa-psk “password”
Ethernet/RNDIS gadget (g_ether)
… or on host side, usbnet and random hwaddr
Note on some boards, usb0 is automaticly setup with an init script
iface usb0 inet static
address 192.168.5.20
netmask 255.255.255.0
network 192.168.5.0
The Moxa IP address is 192.168.5.127
so this should work right ?
but is it not
why?
