Free build peer packets software for linux

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.

BioCluster is a peer-to-peer clustering platform for Asterisk, the open source PBX, which allows Asterisk to be used as a full carrier-grade telephony solution. This project is meant to be installed on several machines together with Asterisk, turning them into a VoIP cluster.

While the BioCluster peer-to-peer protocol was initially designed to cater to Asterisk-based clustering solutions, the BioCluster framework is capable of being extended to support various forms of normally unclustered devices or software packages.

pyraknet is a Python extension that has bindings for the reliable UDP network library RakNet.
pyraknet allows you to concentrate on your game or application rather then writing a your own networking code. pyraknet is straightforward to implement and you only need a small amount of TCP/IP networking knowledge.
Main features:
- Easy to implement
- Cross platform
- High performance
- Low bandwidth overhead
- Automatic peer management. Each client is assigned an identifier.
- Optonally specify packets to be reliable -- packets will automatically resend themselves if dropped.
- Optonally specify packets to arrive in the right order, or to be discarded if it receives an old packet.
Enhancements:
- pyraknets license has changed to LGPL.
- There are now Mac OS X binaries and a few new methods.

The fairly fast packet filter (FFPF) is an approach to network packet processing that adds many new features to existing filtering solutions like BPF.
fairly fast packet filter is designed for high speed by pushing computationally intensive tasks to the kernel or even network processors and by minimising packet copying.
By providing both access to richer programming languages and explicit extensibility, it is also considerably more flexible than existing approaches.
FFPF provides a complete solution for network monitoring that caters to all applications available today. Exploiting its extensibility, the language can even be used as a meta-filter to `script together filters from other approaches, such as BPF.
Main features:
- fast: processes significantly more packets per second than LSF (reference)
- scalable: transparently supports hardware assist, like that given by the Intel IXP2x00 network processors
- backward compatible: supports all existing libpcap based applications
- extensible: separates functionality from the framework. FFPF currently ships with implementations of BPF, Aho Corasick, Boyer Moore Horspool, and many more
- modular: new functions can be written in as little as 3 lines of code
- secure: relies on Keynote for authentication and resource control
- open and standard adherent: licensed under the GNU General Public License (GPL). It implements the Monitoring API (MAPI) draft as designed by the EU-SCAMPI consortium
Enhancements:
- enabled kernelspace processing
- enabled all 5 buffer implementations (Continuous, Fixed-size slot, Variable sized slot, Double ring and Index)
- added TCP stream reassembly and early implementation of zero-copy reassembly
- added PCAP input and output support, for userspace testing and offline use
- added additional minor functions: TCP Synprotect, output to files, ...
- added support for UDEV
- extended controlplane: flowspaces can now be queried for live state
- fixed up many bugs, hacks and irregularities.

PeerProtect is an addon for Jays firewall that generates a file which contains all IP addresses from the RIAA and MPAA, etc. and will protect peer-to-peer programs from them. The Database can be copied from PEERGUARDIAN or IPPREFIX.

Net::DHCP::Packet is a Perl module with object methods to create a DHCP packet.

SYNOPSIS

use Net::DHCP::Packet;

my $p = new Net::DHCP::Packet->new(
Chaddr => 000BCDEF,
Xid => 0x9F0FD,
Ciaddr => 0.0.0.0,
Siaddr => 0.0.0.0,
Hops => 0);

Represents a DHCP packet as specified in RFC 1533, RFC 2132.

CONSTRUCTOR

This module only provides basic constructor. For "easy" constructors, you can use the Net::DHCP::Session module.

new( )

new( BUFFER )

new( ARG => VALUE, ARG => VALUE... )

Creates an Net::DHCP::Packet object, which can be used to send or receive DHCP network packets. BOOTP is not supported.

Without argument, a default empty packet is created.

$packet = Net::DHCP::Packet();

A BUFFER argument is interpreted as a binary buffer like one provided by the socket recv() function. if the packet is malformed, a fatal error is issued.

use IO::Socket::INET;
use Net::DHCP::Packet;

$sock = IO::Socket::INET->new(LocalPort => 67, Proto => "udp", Broadcast => 1)
or die "socket: $@";

while ($sock->recv($newmsg, 1024)) {
$packet = Net::DHCP::Packet->new($newmsg);
print $packet->toString();
}

To create a fresh new packet new() takes arguments as a key-value pairs :

1 = BOOTREQUEST, 2 = BOOTREPLY
Htype htype 1 Hardware address type, see ARP section in "Assigned

ethernet).

when booting via a relay agent.
Xid xid 4 Transaction ID, a random number chosen by the
