An ARP probe in IPv4 is an ARP request constructed with the SHA of the probing host, an SPA of all 0s, a THA of all 0s, and a TPA set to the IPv4 address being probed for. If some host on the network regards the IPv4 address (in the TPA) as its own, it will reply to the probe (via the SHA of the probing host) thus informing the probing host of ...
The arptables computer software utility is a network administrator's tool for maintaining the Address Resolution Protocol (ARP) packet filter rules in the Linux kernel firewall modules. The tools may be used to create, update, and view the tables that contain the filtering rules, similarly to the iptables program from which it was developed.

Linux also features iwspy, to read the signal, noise and quality of a wireless connection. Other related tools for configuring Ethernet adapters are: ethtool, mii-tool, and mii-diag in Linux and the command dladm show-link in Solaris. The ip suite has a similar purpose and is meant to replace the deprecated ifconfig. [6]
