Decapsulate traffic encapsulated within GRE, IPIP, 6in4 and ESP protocols
from a pcap file.
Can also remove IEEE 802.1Q (virtual lan - vlan) header.
Paris traceroute is a new version of the well-known network diagnosis
and measurement tool. It addresses problems caused by load balancers
with the initial implementation of traceroute.
Panoptis is a project started some time ago,
with the aim to stop the Denial of Service
and Distributed Denial of Service attacks that
have been torturing the Internet for the last
few years.
It is based on real-time processing of Cisco (R)
NetFlow (TM) data, since this seems to be the
most efficient approach as it is router-centric,
allowing for automated central response without
intervention from the affected organizations'
network administrators.
Gspoof is a GTK+ program written in C language which makes easier
and accurate the building and the sending of TCP packet with a
data-payload or not. It's possible to modify TCP/IP fields also
Ethernet header working to Link Level.
Plugdaemon acts as a "dumb proxy", forwarding a TCP/IP stream from a port
on one host to a possibly different port on a separate host. It runs as a
daemon to reduce latency in setting up a connection, and optionally logs
every connection via syslog.
PoPToP is a PPTP daemon. It is compatible with the Microsoft Windows
VPN adapter.
Portfwd stands for port forwarding daemon. It's a small C++
utility which forwards incoming TCP connections and/or UDP
packets to remote hosts.
This program forces any TCP connection made by any given TCP client
to follow through proxy (or proxy chain). It is a kind of proxifier.
It acts like sockscap / permeo / eborder driver (intercepts TCP calls).
This is a port of the "pptp-linux" PPTP client. It can establish a
PPP connection with an NT server, tunneled through a PPTP link over
the Internet. In effect, it makes the client machine behave as if
it were on the same LAN as the server.
John Polstra has created the port, including bug fixes that were
subsequently integrated in the upstream release, and a patch to
use FreeBSD's userland "ppp" package rather than "pppd" which it
was originally designed to use.
There is no manpage for this package, but you will find some
quickstart instructions and example configuration files in
"${PREFIX}/share/examples/pptpclient".
ptpd2 is an implementation of version 2 the Precision Time Protocol
(IEEE 1588-2008)
PTP was developed to provide very precise time coordination of LAN connected
computers.
