packETH 1.4
packETH is a Linux GUI packet generator tool for ethernet. more>>
packETH is a Linux GUI packet generator tool for ethernet. The project allows you to create and send any possible packet or sequence of packets on the ethernet.
Main features:
you can create and send any ethernet packet. Supported protocols:
- ethernet II, ethernet 802.3, 802.1q, QinQ
- ARP, IPv4, user defined network layer payload
- UDP, TCP, ICMP, IGMP, user defined transport layer payload
- RTP (payload with options to send sin wave of any frequency for G.711)
sending sequence of packets
- delay between packets, number of packets to send
- sending with max speed, approaching the teoretical boundary
- change parameters while sending (change IP & mac address, UDP payload, 2 user defined bytes, etc.)
saving configuration to a text file and load from it.
Enhancements:
- new features

Packet Garden is a project that allows you to grow a world from network traffic.
Packet Garden captures information about how you use the internet and uses this stored information to grow a private world you can later explore.
To do this, Packet Garden takes note of all the servers you visit, their geographical location and the kinds of data you access.
Uploads make hills and downloads valleys, their location determined by numbers taken from internet address itself.
The size of each hill or valley is based on how much data is sent or received.
Plants are also grown for each protocol detected by the software; if you visit a website, an HTTP plant is grown. If you share some files via eMule, a Peer to Peer plant is grown, and so on.

NetPacket::IP 0.04
NetPacket::IP is a Perl module to assemble and disassemble IP (Internet Protocol) packets. more>>
SYNOPSIS
use NetPacket::IP;
$ip_obj = NetPacket::IP->decode($raw_pkt);
$ip_pkt = NetPacket::IP->encode($ip_obj);
$ip_data = NetPacket::IP::strip($raw_pkt);
NetPacket::IP provides a set of routines for assembling and disassembling packets using IP (Internet Protocol).
Methods
NetPacket::IP->decode([RAW PACKET])
Decode the raw packet data given and return an object containing instance data. This method will quite happily decode garbage input. It is the responsibility of the programmer to ensure valid packet data is passed to this method.
NetPacket::IP->encode()
Return an IP packet encoded with the instance data specified. This will infer the total length of the packet automatically from the payload lenth and also adjust the checksum.
Functions
NetPacket::IP::strip([RAW PACKET])
Return the encapsulated data (or payload) contained in the IP packet. This data is suitable to be used as input for other NetPacket::* modules.
This function is equivalent to creating an object using the decode() constructor and returning the data field of that object.
Instance data
The instance data for the NetPacket::IP object consists of the following fields.
ver
The IP version number of this packet.
hlen
The IP header length of this packet.
flags
The IP header flags for this packet.
foffset
The IP fragment offset for this packet.
tos
The type-of-service for this IP packet.
len
The length (including length of header) in bytes for this packet.
id
The identification (sequence) number for this IP packet.
ttl
The time-to-live value for this packet.
proto
The IP protocol number for this packet.
cksum
The IP checksum value for this packet.
src_ip
The source IP address for this packet in dotted-quad notation.
dest_ip
The destination IP address for this packet in dotted-quad notation.
options
Any IP options for this packet.
data
The encapsulated data (payload) for this IP packet.

deja-packet 1.0
deja-packet transmits raw packets through a specified interface. more>>
deja-packet transmits raw packets through a specified interface.
Usage: ./deja-packet -pcap < libpcap capture file > < interface name >
or: ./deja-packet -raw < raw packet file > < interface name >
Note: you must be root to successfully transmit packets with deja-packet due to the Linux security restrictions with raw sockets.
In the [-p]cap mode, deja-packet transmits selected packets from a libpcap capture file (such as one created by Ethereal/Wireshark, or tcpdump). In the [-r]aw mode, deja-packet transmits the raw contents of a file as one whole packet.
The [-p]cap mode is interactive: the user will be continuously prompted to select which packet from the libpcap capture file to transmit, until the “q” character is encountered, where the program will quit.
Example pcap mode:
$ sudo ./deja-packet -p icmp_ping.pcap eth0
Select packet number (1 to 6) for transmission or q for quit: 1
Successfully transmitted packet!
Select packet number (1 to 6) for transmission or q for quit: 2
Successfully transmitted packet!
Select packet number (1 to 6) for transmission or q for quit: 5
Successfully transmitted packet!
Select packet number (1 to 6) for transmission or q for quit: 6
Successfully transmitted packet!
Select packet number (1 to 6) for transmission or q for quit: q
$
In the [-r]aw mode, deja-packet exits immediately after the attempted transmission is complete (allows deja-packet to be easily used with a script).
Example raw mode:
$ sudo ./deja-packet -r samplepacket eth0
Successfully transmitted packet!
$
icmp_ping.pcap is included as a sample libpcap capture file.
To compile deja-packet, simply use the command “make”.
deja-packet remains Linux-only because it requires PF_PACKET sockets.
This project is released under the GNU General Public License version 2.

NetPacket::ICMP->decode([RAW PACKET])
Decode the raw packet data given and return an object containing instance data. This method will quite happily decode garbage input. It is the responsibility of the programmer to ensure valid packet data is passed to this method.
NetPacket::ICMP->encode()
Return an ICMP packet encoded with the instance data specified.
<<lessSYNOPSIS
use NetPacket::ICMP;
$icmp_obj = NetPacket::ICMP->decode($raw_pkt);
$icmp_pkt = NetPacket::ICMP->encode();
$icmp_data = NetPacket::ICMP::strip($raw_pkt);

Packet Construction Set 0.5 Beta
Packet Construction Set is a set of Python modules and objects that make building network protocol code easier. more>>
Packet Construction Set is a set of Python modules and objects that make building network protocol code easier for the protocol developer.
The core of the system is the pcs module itself which provides the necessary functionality to create classes that implement packets.
Installation Instructions for Packet Construction Set (PCS)
PCS follows the normal Python conventions for building and installing and there is very little, if any, magic. To install the library and the associated packet classes into your system do:
> python setup.py install < return >
To test your installation do:
> cd tests/ < return >
> python *.py
Some tests fail if you do not have enough privileges to work with the Berkeley Packet Filter. If you wish to run those tests run them using sudo.
To build the documentation you will need pdflatex and a BSD version of make installed. Go into the docs directory and build the documentation:
> cd docs/ < return >
> bsdmake all
you will see PDF versions of the docs.
Enhancements:
- Move my version of Doug Songs Python pcap library into the package.
- Update the Makefile to make sure that we install correctly no matter what target is selected.

RADIUS::Packet 1.0
RADIUS::Packet is an object-oriented Perl interface to RADIUS packets. more>>
RADIUS::Packet is an object-oriented Perl interface to RADIUS packets.
SYNOPSIS
use RADIUS::Packet;
use RADIUS::Dictionary;
my $d = new RADIUS::Dictionary "/etc/radius/dictionary";
my $p = new RADIUS::Packet $d, $data;
$p->dump;
if ($p->attr(User-Name eq "lwall") {
my $resp = new RADIUS::Packet $d;
$resp->set_code(Access-Accept);
$resp->set_identifier($p->identifier);
$resp->set_authenticator($p->authenticator);
$resp->set_attr(Reply-Message) = "Welcome, Larry!rn";
my $respdat = auth_resp($resp->pack, "mysecret");
...
RADIUS (RFC2138) specifies a binary packet format which contains various values and attributes. RADIUS::Packet provides an interface to turn RADIUS packets into Perl data structures and vice-versa.
RADIUS::Packet does not provide functions for obtaining RADIUS packets from the network. A simple network RADIUS server is provided as an example at the end of this document. Also, a RADIUS::Server module is under development which will simplify the interface.

Tapioca VoIP 0.3.9
Tapioca is a framework for Voice over IP (VoIP) and Instant Messaging (IM). more>>
Tapioca is a framework for Voice over IP (VoIP) and Instant Messaging (IM). Its main goal is to provide an easy way for developing and using VoIP and IM services in any kind of application.
Tapioca VoIP project was designed to be cross-platform, lightweight, thread-safe, having mobile devices and applications in mind.
Main features:
- Create a solution that integrates all components used by VoIP and IM applications in a single, reliable and easy to use framework, which is able to work on different platforms.
- Spare resources, providing central services for multiple applications. Eg.: The control of all incoming and outgoing SIP requests are managed by the SIP service, avoiding the creation of one SIP stack and allocation of a network port for each SIP-based application.
- Reduce the overhead of control layers and library dependencies.

Advanced Packet Sniffer 0.19
Aps is a small tool for analyzing network traffic. more>>
Aps is a small tool for analyzing network traffic. It prints out a great deal of information about the relevant protocols including TCP, UDP, ARP, and ICMP.
It allows you to filter IP addresses, hardware addresses, ports, and specific protocols. It comes with a little GTK-GUI displaying packet counters for each protocol.
APS tries to print detailed info about network frames that are received from the SOCK_RAW (ETH_P_ALL) socket. I am not sure if this is the clean way, but it works fine. APS prints info about the hardware layer and the IP and TCP/UDP/ICMP header.
The tail of the packet (mostly the data) wich could not be interpreted is written on the screen as ascii/hex-dump or both (your choice).
