ARP-SK(1)arp-sk - A swiss knife tool for ARP ARP-SK(1)NAMEarp-sk - A swiss knife tool for ARP
SYNOPSISarp-sk MODE OPTIONS
where MODE is either one among BASIC or ADVANCED and OPTIONS lets you
control each address of the ARP message (at link and logical layers -
i.e. Ethernet and IP addresses), and lots of other sending parameters
(interface, frequency, amount, and so on).
DESCIRPTIONarp-sk is an ARP packet generator aimed to illustrate ARP protocol
fails. It allows custom packets to be generated from link layer to ARP
layer.
It supports currently only Ethernet and IP protocols but is designed to
also work with other addresses (in a far away future ;-)
BASIC MODES-w, --who-has
Send an ARP Who-has.
-r, --reply
Send a ARP Reply.
ADVANCED MODES
None are yet implemented but they should appear very soon. They should
be considered as combinations and shortcuts of what you can do by send‐
ing several basic packets.
-o, --spoof
For those used to Dug Song's arpspoof in dsniff (NOT YET IMPLE‐
MENTED)
-p, --arping
(bad) RARP emulation. (NOT YET IMPLEMENTED)
-m, --arpmim
Man in the Middle. (NOT YET IMPLEMENTED)
LINK LAYER OPTIONS
These parameters let you control what will appear in the packet at link
layer (Ethernet addresses of the ARP message). These addresses don't
need to be the same as those specified in the ARP message itself. The
RFC 826 (ARP's one) does not specify that there must be some consis‐
tency between ARP and Ethernet layer. That means you can provide uncor‐
related addresses between these 2 layers.
This is very useful if you want reach all hosts on the network (use
broadcast address as destination) or a particular host (the gateway for
instance), or you can hide the source of the ARP message by providing a
fake source address.
Here, you can provide either a hostname, an IP address or a MAC
address. If you use a hostname or an IP address and that Ethernet
address is not present in your ARP cache, a malformed DNS packet is
sent to the target. But since the cache does not contain the Ethernet
address, an ARP query is firstly sent on the network. The target
answers with an ARP and you got the Ethernet address.
-d, --dst HOST
Set link layer destination. HOST can be a hostname, an IP
address or a MAC address.
-s, --src HOST
Set link layer source. HOST can be a hostname, an IP address or
a MAC address.
--rand-hwa
Set random addresses in link header
--rand-hwa-dst
Set random destination in link header.
--rand-hwa-src
Set random source in link header.
LOGICAL LAYER OPTIONS
These parameters let you control what will appear in the ARP message
itself, that is mainly the pairs <IP:MAC> for both source and destina‐
tion hosts.
You can specify either both IP and MAC (1.1.1.1:11:11:11:11:11:11),
only IP (1.1.1.1, information provided is the link layer will be used
to complete the ARP message), or only MAC (:11:11:11:11:11:11, then IP
is set to broadcast).
-D, --arp-dst HOST[:MAC]
Set logical layer destination. HOST can be a hostname or an IP
address. A MAC address can be specified with MAC. If not, HOST
will be resolved.
-S, --arp-src HOST[:MAC]
Set logical layer source. HOST can be a hostname or an IP
address. A MAC address can be specified with MAC. If not, HOST
will be resolved.
--rand-arp
Set random addresses in ARP message.
--rand-arp-dst
Set random destination adsresses in ARP message.
--rand-arp-src
Set random source addresses in ARP message.
--rand-arp-hwa-dst
Set random destination MAC address in ARP message.
--rand-arp-log-dst
set random dst IP address in ARP message.
--rand-arp-hwa-src
Set random source MAC address in ARP message.
--rand-arp-log-src
Set random source IP address in ARP message.
MISCELLANEOUS OPTIONS-i, --interface IFACE
Use IFACE as output interface (default: eth0).
-c, --count NUM
Send NUM packets
-T, --time NUM
Wait the NUM seconds between sending each packet ( NUM can be
prefixed with u for microseconds)
--rand-time NUM
Randomize the sending period of the packets by adding a random
salt choosen between -NUM and NUM.
--beep Beep for each packet sent.
--use-ts
Send an icmp-timestamp to resolve MAC to IP.
-n, --network ADDRESS
Use ADDRESS as broadcast address for sending icmp-timestamp.
-N, --call-dns
Force address name resolution. This should never be used since
it sends DNS messages on the LAN and slows down performances of
arp-sl.
-V, --version
Print version and exit.
-h, --help
