================================================================================
1. IMPORTANT NOTICE
================================================================================
Since ArpON 3.0-ng (next generation), ArpON has been rewritten from scratch,
therefore all the old versions of ArpON (lower of 3.0-ng) are deprecated.
Please upgrade all installations of ArpON and read carefully the documentation
and the man page of ArpON.
================================================================================
2. WHAT IS ARPON?
================================================================================
ArpON (ARP handler inspection) is a Host-based solution that make the ARP
standardized protocol secure in order to avoid the Man In The Middle (MITM)
attack through the ARP spoofing, ARP cache poisoning or ARP poison routing
attack.
This is possible using three kinds of anti ARP spoofing techniques:
1. SARPI (Static ARP Inspection) for the statically configured networks
without DHCP;
2. DARPI (Dynamic ARP Inspection) for the dynamically configured networks
with DHCP;
3. HARPI (Hybrid ARP Inspection) for the statically and dynamically
configured networks with DHCP.
The goal of ArpON is therefore to provide a secure and efficient network daemon
that provides the SARPI, DARPI and HARPI anti ARP spoofing technique, thus
making the ARP standardized protocol secure from any foreign intrusion.
================================================================================
3. FEATURES
================================================================================
The features of ArpON are:
• FREE. ArpON is released under the BSD open source license. This means that
you have total freedom to modify and use it with your system, even if it's
commercial.
• POPULAR. ArpON is used as the network daemon by many users, both the
network managers and academic researchers. ArpON is downloaded several
hundred of times every month.
• TESTED AND RELIABLE. Many users have contributed over the years in testing
ArpON on a wide range of Man In The Middle (MITM) attack tools through the
ARP spoofing, ARP cache poisoning or ARP poison routing.
• EASY TO USE. ArpON is distributed as a single tarball that once compiled,
runs on every supported Operating System. You launch the executable, and
from that moment the Operating System is able to avoid the Man In The
Middle (MITM) attack through the ARP spoofing, ARP cache poisoning or ARP
poison routing.
• MULTI-PLATFORM. Many developers have contributed over the years in porting
ArpON on a wide range of GNU/Linux distributions.
• COMPATIBLE AND PORTABLE. ArpON is completely compatible with the ARP
standardized protocol. ArpON is an network daemon that runs in user space,
this also means that ArpON will be easily portable to other Operating
Systems.
• WELL DOCUMENTED. The documentation of ArpON is easy and complete. The
documentation contains the retrieving tutorial; the building tutorial; the
installation tutorial; the user tutorial with many examples and scenarios;
the development tutorial with the Activity diagrams of the SARPI, DARPI
and HARPI anti ARP spoofing technique and with modular source code well
commented; the bug report tutorial that takes you step-by-step through all
of the features of ArpON.

================================================================================
12. ARPON DAEMON
================================================================================
The synopsis of ArpON daemon command is:
arpon [OPTIONS] [SARPI | DARPI | HARPI]
ArpON sets of policies in the ARP cache for all the static and or dynamic
entries matching the specified network interface (or that matching the several
specified network interfaces if run concurrently several daemons of ArpON for
different network interfaces), through the run of SARPI, DARPI or HARPI anti
ARP spoofing technique.
ArpON have to be run with the root privileges. ArpON have to be configured using
command-line options and a configuration file. ArpON reloads the configuration
of the specified network interface and rereads its configuration file when it
receives a hangup signal (SIGHUP) by executing itself with the name and options
it was started with. ArpON exits correctly when it receives an interrupt signal
(SIGINT) or a termination signal (SIGTERM).
================================================================================
13. IMPORTANT NOTE
================================================================================
The ArpON daemon sets two fundamental kernel network parameters via the sysctl
interface on the specified network interface:
1. The arp_ignore kernel parameter of the specified network interface is
always setted to 8 by ArpON. This is done to disable, in the specified
network interface of the Operating System, the sending of the ARP replies in
response to received ARP requests for all local addresses (the ARP replies
on the specified network interface, will be sent by ArpON instead of the
Operating System).
2. The arp_accept kernel parameter of the specified network interface is
always setted to 0 by ArpON. This is done to disable, in the specified
network interface of the Operating System, the creating of the new IP
entries in the ARP cache triggered by the unsolicited and gratuitous ARP
requests and replies (the IP entries in the ARP cache on the specified
network interface, will be created or updated by ArpON as static or dynamic
IP entries instead of the Operating System).
The ArpON daemon restores the previously values read from the arp_ignore and
arp_accept kernel parameters of the specified network interface when it receives
an interrupt signal (SIGINT) or a termination signal (SIGTERM). Remember to
restore the values of the arp_ignore and arp_accept kernel parameters of the
specified network interface (the default values are 0 for both), if you have
terminated the ArpON daemon with other signals, e.g. kill signal (SIGKILL).
================================================================================
14. OPTIONS SUMMARY
================================================================================
The available options of ArpON daemon command are:
• General options:
-d, --daemon
Daemonize the ArpON.
-i, --interface <interface>
Use the specified network interface.
• SARPI 'Static ARP Inspection' option:
SARPI anti ARP spoofing technique manages and sets the policies in the ARP
cache only for all the static entries matching the specified network
interface, in order to avoid the Man In The Middle (MITM) attack through
the ARP spoofing, ARP cache poisoning or ARP poison routing. Therefore
SARPI is an optimal choice in those statically configured networks
without DHCP. SARPI sets these policies:
1) CLEAN: SARPI cleans from the ARP cache only all the entries matching
the specified network interface, that are present or not present in the
configuration file;
2) UPDATE: SARPI updates in the ARP cache only all the static entries
matching the specified network interface, that are present in the
configuration file;
3) REFRESH: SARPI refreshes in the ARP cache only a static entry matching
the specified network interface, that is present in the configuration
file;
4) ALLOW: SARPI sets up in the ARP cache only a dynamic entry matching the
specified network interface, that is not present in the configuration
file.
Therefore SARPI requires a specified network interface and the
specification in the configuration file of the ARP cache only for all the
static entries matching the specified network interface.
-S, --sarpi
Run SARPI anti ARP spoofing technique.
• DARPI 'Dynamic ARP Inspection' option:
DARPI anti ARP spoofing technique manages and sets the policies in the ARP
cache only for all the dynamic entries matching the specified network
interface, in order to avoid the Man In The Middle (MITM) attack through
the ARP spoofing, ARP cache poisoning or ARP poison routing. Therefore
DARPI is an optimal choice in those dynamically configured networks with
DHCP. DARPI sets these policies:
1) CLEAN: DARPI cleans from the ARP cache only all the entries matching
the specified network interface;
2) ALLOW: DARPI sets up in the ARP cache only a dynamic entry matching
the specified network interface;
3) DENY: DARPI cleans up from the ARP cache only a dynamic entry matching
the specified network interface.
Therefore DARPI requires a specified network interface and it doesn't
requires any specification in the configuration file of the ARP cache only
for all the dynamic entries matching the specified network interface.
-D, --darpi
Run DARPI anti ARP spoofing technique.
• HARPI 'Hybrid ARP Inspection' option:
HARPI anti ARP spoofing technique manages and sets the policies in the ARP
cache for both all the static and dynamic entries matching the specified
network interface, in order to avoid the Man In The Middle (MITM) attack
through the ARP spoofing, ARP cache poisoning or ARP poison routing.
Therefore HARPI is an optimal choice in those statically and dynamically
configured networks with DHCP. HARPI sets and combines these policies of
the SARPI and DARPI:
1) CLEAN: HARPI cleans from the ARP cache only all the entries matching
the specified network interface, that are present or not present in the
configuration file;
2) UPDATE: HARPI updates in the ARP cache only all the static entries
matching the specified network interface, that are present in the
configuration file;
3) REFRESH: HARPI refreshes in the ARP cache only a static entry matching
the specified network interface, that is present in the configuration
file;
4) ALLOW: HARPI sets up in the ARP cache only a dynamic entry matching
the specified network interface, that is not present in the
configuration file;
5) DENY: HARPI cleans up from the ARP cache only a dynamic entry matching
the specified network interface, that is not present in the
configuration file.
Therefore HARPI requires a specified network interface, the specification
in the configuration file of the ARP cache only for all the static entries
matching the specified network interface; instead it doesn't requires any
specification in the configuration file of the ARP cache only for all the
dynamic entries matching the specified network interface.
-H, --harpi
Run HARPI anti ARP spoofing technique.
• Standard options:
-v, --version
Print the version and exit.
-h, --help
Print the help screen and exit.
================================================================================
15. FILES
================================================================================
The available files of ArpON daemon command are:
• The configuration file contains the configuration data of ArpON and it is
used when run the SARPI or HARPI anti ARP spoofing technique, for the
specification in the ARP cache only for all the static entries matching
the specified network interface (or that matching the several specified
network interfaces if run concurrently several daemons of ArpON for
different network interfaces). This file should be writable by root only
but it is recommended (though not necessary) that it be world-readable.
Please note that:
If you chose the default "/" path of the installation, the configuration
file is:
/etc/arpon.conf
Else the configuration file is:
PATH/etc/arpon.conf
where PATH is the path of your installation.
• The log file contains the log data of ArpON. If there are several
daemons of ArpON running concurrently for different network interfaces,
this contains the log data of all the daemons of ArpON. This file should
be readable only by root, and need not be readable by anyone else. Please
note that:
If you chose the default "/" path of the installation, the log file is:
/var/log/arpon.log
Else the log file is:
PATH/log/arpon.log
where PATH is the path of your installation.
• The pid file contains the process ID of ArpON. If there are several
daemons of ArpON running concurrently for different network interfaces,
this contains the process ID of the one started last. The content of this
file is not sensitive; it can be world-readable. Please note that:
If you chose the default "/" path of the installation, the pid file is:
/var/run/arpon.pid
Else the pid file is:
PATH/run/arpon.pid
where PATH is the path of your installation.
================================================================================
16. EXAMPLES
================================================================================
These examples shows how to use all three kinds of anti ARP spoofing techniques
of ArpON daemon. Note that these examples use the default "/" path of the
installation of the files.
In the same host, we have three network interfaces with different subnet classes
and we would set the ARP cache for all the static and dynamic entries matching
the eth0, wlan0 and eth1 network interfaces. This scenario requires the run
concurrently of three daemons of ArpON:
• SARPI 'Static ARP Inspection' example:
The eth0 network interface has the 192.168.1.2/24 IP address. We have only
three static entries of the ARP cache:
1) 192.168.1.1 at 58:ac:78:10:b9:77;
2) 192.168.1.3 at d4:be:d9:fe:8b:45;
3) 192.168.1.4 at 90:94:e4:bb:1c:10.
and we have no dynamic entries of the ARP cache. This is the ideal case
where we have to use the SARPI anti ARP spoofing technique, therefore
specify in the configuration file of the ARP cache only all the static
entries matching the eth0 network interface:
$ sudo nano /etc/arpon.conf
Therefore:
#
# ArpON configuration file.
#
# See the arpon(8) man page for details.
#
#
# Static entries matching the eth0 network interface:
#
# First static entry:
192.168.1.1 58:ac:78:10:b9:77
# Second static entry:
192.168.1.3 d4:be:d9:fe:8b:45
# Third static entry:
192.168.1.4 90:94:e4:bb:1c:10
Daemonize the ArpON and run SARPI anti ARP spoofing technique on the eth0
network interface:
$ sudo arpon -d -i eth0 -S
Read the log file:
$ sudo tail -f /var/log/arpon.log
Read the pid file:
$ cat /var/run/arpon.pid
• DARPI 'Dynamic ARP Inspection' example:
The wlan0 network interface has the 172.16.1.2/24 IP address. We have no
static entries of the ARP cache, and we have only dynamic entries of the
ARP cache. This is the ideal case where we have to use the DARPI anti ARP
spoofing technique, therefore daemonize the ArpON and run DARPI anti ARP
spoofing technique on the wlan0 network interface:
$ sudo arpon -d -i wlan0 -D
Read the log file:
$ sudo tail -f /var/log/arpon.log
Read the pid file:
$ cat /var/run/arpon.pid
• HARPI 'Hybrid ARP Inspection' example:
The eth1 network interface has the 10.0.1.2/16 IP address. We have only
two static entries of the ARP cache:
1) 10.0.1.1 at 58:ac:78:88:1a:bb;
2) 10.0.10.1 at 90:94:e4:7e:f4:59.
and we have the rest of entries as dynamic entries of the ARP cache. This
is the ideal case where we have to use the HARPI anti ARP spoofing
technique, therefore specify in the configuration file of the ARP cache
only all the static entries matching the eth1 network interface:
$ sudo nano /etc/arpon.conf
Therefore:
#
# ArpON configuration file.
#
# See the arpon(8) man page for details.
#
#
# Static entries matching the eth0 network interface:
#
# First static entry:
192.168.1.1 58:ac:78:10:b9:77
# Second static entry:
192.168.1.3 d4:be:d9:fe:8b:45
# Third static entry:
192.168.1.4 90:94:e4:bb:1c:10
#
# Static entries matching the eth1 network interface:
#
# First static entry:
10.0.1.1 58:ac:78:88:1a:bb
# Second static entry:
10.0.10.1 90:94:e4:7e:f4:59
Daemonize the ArpON and run HARPI anti ARP spoofing technique on the eth1
network interface:
$ sudo arpon -d -i eth1 -H
Read the log file:
$ sudo tail -f /var/log/arpon.log
Read the pid file:
$ cat /var/run/arpon.pid
================================================================================
17. HOW TO USE ARPON
================================================================================
The available scenarios of ArpON, that explain respectively how ArpON works and
how to use ArpON are:
• Half-duplex ArpON defense:
This scenario shows the half-duplex Man In The Middle (half-duplex MITM)
attack through the ARP spoofing. The attacker is attacking only the host
A, therefore the attacker is intercepting only the communications from the
host A to host B:
If you chose the default "/" path of the installation, open with an image
viewer application this file:
/usr/share/doc/arpon/scenario/halfduplexattack.jpg
or open with a Pdf viewer application this file:
/usr/share/doc/arpon/scenario/halfduplexattack.pdf
or open with the OpenOffice Draw application this file:
/usr/share/doc/arpon/scenario/halfduplexattack.odg
Else open with an image viewer application this file:
PATH/share/doc/arpon/scenario/halfduplexattack.jpg
or open with a Pdf viewer application this file:
PATH/share/doc/arpon/scenario/halfduplexattack.pdf
or open with the OpenOffice Draw application this file:
PATH/share/doc/arpon/scenario/halfduplexattack.odg
Run the ArpON only in the host A in order to avoid the half-duplex attack:
If you chose the default "/" path of the installation, open with an image
viewer application this file:
/usr/share/doc/arpon/scenario/halfduplexdefense.jpg
or open with a Pdf viewer application this file:
/usr/share/doc/arpon/scenario/halfduplexdefense.pdf
or open with the OpenOffice Draw application this file:
/usr/share/doc/arpon/scenario/halfduplexdefense.odg
Else open with an image viewer application this file:
PATH/share/doc/arpon/scenario/halfduplexdefense.jpg
or open with a Pdf viewer application this file:
PATH/share/doc/arpon/scenario/halfduplexdefense.pdf
or open with the OpenOffice Draw application this file:
PATH/share/doc/arpon/scenario/halfduplexdefense.odg
The communications between the host A and the host B are back again
secure, leaving the attacker out.
• Full-duplex ArpON defense:
This scenario shows the full-duplex Man In The Middle (full-duplex MITM)
attack through the ARP spoofing. The attacker is attacking both the host
A and the host B, therefore the attacker is intercepting all the
communications between the host A and the host B:
If you chose the default "/" path of the installation, open with an image
viewer application this file:
/usr/share/doc/arpon/scenario/fullduplexattack.jpg
or open with a Pdf viewer application this file:
/usr/share/doc/arpon/scenario/fullduplexattack.pdf
or open with the OpenOffice Draw application this file:
/usr/share/doc/arpon/scenario/fullduplexattack.odg
Else open with an image viewer application this file:
PATH/share/doc/arpon/scenario/fullduplexattack.jpg
or open with a Pdf viewer application this file:
PATH/share/doc/arpon/scenario/fullduplexattack.pdf
or open with the OpenOffice Draw application this file:
PATH/share/doc/arpon/scenario/fullduplexattack.odg
Run the ArpON only in the host A in order to avoid the half-duplex attack:
If you chose the default "/" path of the installation, open with an image

21. ACTIVITY DIAGRAMS
================================================================================
All the available algorithms of ArpON are compatible with the ARP standardized
protocol as described in these official RFC documents:
1. RFC 826:
http://tools.ietf.org/html/rfc826
2. RFC 2131:
http://tools.ietf.org/html/rfc2131
3. RFC 3927:
http://tools.ietf.org/html/rfc3927
4. RFC 5227:
http://tools.ietf.org/html/rfc5227
Note that all the available algorithms of ArpON set the arp_ignore and the
arp_accept fundamental kernel network parameters via the sysctl interface as
described in this official kernel document:
1. IP sysctl:
http://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt
Therefore the available Activity diagrams of ArpON, that explain respectively
the algorithms and the policies of all three kinds of anti ARP spoofing
techniques are:
• SARPI 'Static ARP Inspection' Activity diagram:
If you chose the default "/" path of the installation, open with an image
viewer application this file:
/usr/share/doc/arpon/uml/SARPI.jpg

To understand the SARPI 'Static ARP Inspection' Activity diagram, it is
very important to understand this network diagram, that show a simple
case of execution of the SARPI algorithm, in order to permit the
communication between the host A (with a static IP address) and the host
B (with a static IP address):

To understand the DARPI 'Dynamic ARP Inspection' Activity diagram, it is
very important to understand this network diagram, that show a simple
case of execution of the DARPI algorithm, in order to permit the
communication between the host A (with a dynamic IP address) and the host
B (with a dynamic IP address), checking any network errors:
