The arping utility sends ARP and/or ICMP requests to the specified host and displays the replies. The host may be specified by its hostname, its IP address, or its MAC address. One request is sent each second. When pinging an IP an ARP who-has query is sent. When pinging a MAC address a directed broadcast ICMP Echo request is sent.


Arping – To Discover Hosts on a Computer Network Arping is a computer software tool that is used to discover hosts on a computer network. The program tests whether a given IP address is in use on the local network, and can get additional information about the device using that address.

And then I use this to show the presence in my sitemap etc. .sitemap file Frame label="Anwesenheit" icon="presence"{ Text Solved: Hello, I was wondering if there's an equivalent feature on the ASA to the Linux command 'arping.' My ISP has a gateway in the building whose ARP cache refresh periods are set to some ridiculously long interval. Only useful if you are arpinging many hosts at once. See for an example).-b Like -0 but source broadcast source address ( Note that this may get the arping unanswered since it’s not normal behavior for a host.-B Use instead of host if you want to address count Use the ARP ping (ARPING) function, also known as Send ARP Request (SNDARPRQS), to test reachability of IP version 4 (IPv4) systems on the local LAN by using the Address Resolution Protocol (ARP). The ARPING function sends a broadcast ARP request on a LAN to solicit a reply from the host that uses the specified IP address.

A: Arping when pinging a MAC relies on the host to answer a broadcast ping ( icmp echo request) properly (IIRC: not the windows way). If you want a host to pop  -b Send only MAC level broadcasts.

Arping then listens for ARP replies and prints them (if any), including the ping reply time: These two uses of arping can help diagnose Ethernet and ARP problems--particularly hosts replying for addresses which do not belong to them.. To avoid IP address collisions on dynamic networks (where hosts are turning on and off, connecting and disconnecting and otherwise changing IP addresses) duplicate address detection becomes important. Searching on the web, i find that a possible way is the ARP method: i must send an ARP request to a suspect no broadcast IP to check if it's in promiscuous mode.

Each try invokes arping with a one second timeout. *interface, char *broadcast); extern int netcfg_gateway_reachable(const struct netcfg_interface *interface); 

ARP also includes a ARP Reply message, which include both the original IP address and the matching MAC address of the network device in question. Detailed ARP Request Process Normally arping starts from sending broadcast, and switch to unicast after reply received. -c count Stop after sending count ARP REQUEST packets. With deadline option, instead wait for count ARP REPLY packets, or until the timeout expires. -D Duplicate address detection mode (DAD). See RFC2131, 4.4.1. arping -U If you're spoofing an address, you may need to run this first: echo 1 > /proc/sys/net/ipv4/ip_nonlocal_bind Finally, because of its spoofing ability, sending Unsolicited ARP packets is sometimes considered a "hostile" activity, and may be ignored, or might lead to being blocked by some third-party firewalls.
