[SOLVED] Device (ethernet connection) is pingable from one Linux device but not from another

[tenochtilan]

I have two Debian 8 systems, which can connect via ethernet cable to a circuit board C (ip address: 10.0.0.100)

Debian A: on boot, arp -a does not show the device at all. Upon 'ping 10.0.0.100', board C responds and the device is added to the arp registry on eth1.

Debian B: on boot, arp -a shows '10.0.0.100 on <incomplete>' on eth5 (equivalent to eth1). Upon 'ping 10.0.0.100', typical response is long delays and 'Destination Host is unreachable'.

/etc/network/interfaces on both Debian A and Debian B are set to same parameters (for eth1 and eth5 respectively):
address 10.0.0.1
netmask 255.255.0.0
network 10.0.0.0
broadcast 10.0.255.255

Does anyone know why Debian B is not connecting? I also tried transferring the iptables from Debian A to see if they would work (iptable-restore), with no luck.

SOLVED: Debian B did not have the isc-dhcp-server package installed. After installing and configuring it like Debian A was configured, the connection proceeds.
