Mpd is a netgraph based PPP implementation for FreeBSD. Mpd supports thousands of Sync, Async, PPTP, L2TP, PPPoE, TCP and UDP links in client, server and access concentrator (LAC/PAC/TSA) modes. It is very fast and functional.
A client implementation of Secure Socket Tunneling Protocol (SSTP) for Linux / Mac OS-X that allows remote access via SSTP VPN to Microsoft Windows 2008 Server.
This project has been moved to https://gitlab.com/eivnaes/sstp-client
VTun is the easiest way to create Virtual Tunnels over TCP/IP networks with traffic shaping, compression, and encryption.
It supports IP, Ethernet, PPP and other tunnel types. VTun is easily and highly configurable.
VPN, Mobile IP, Shaping, etc
fli4l is a single-floppy Linux-based ISDN/DSL/ethernet-router. It features configuration with some simple ASCII-files and several possible connection-flavors (in/out/callback, raw IP/PPP, PPPoE).
For new versions, check https://github.com/Darkkey/javaNetSim
javaNetSim (Java Network Simulator) - it's a fork of a project jFirewallSim. The main goal of javaNetSim is creating a software to simulate various TCP/IP networks based on Ethernet, WiFi, PPP, etc...
phpRADmin is a web tool written in PHP to allow configuration, administration and provisioning of RADIUS server (FreeRADIUS), clients (NAS, AP, etc) and users (PPP, PPPoE, EAP, etc) with MySQL as backend.
Slirp is a SLIP/PPP link emulator. Clients think it's a normal connection! The Slirp Maintance Project is what it says: keep Slirp up and running! (Primary Developer needed!)
PyVpn is a software for management VPN connections for GNU/Linux written in Python using pySqlite and pyGtk. With DB support and Wi-Fi support too. It is based on the "iwconfig" utilities and the "ppp" package.
NetChat is a network version of the "chat" utility that comes with PPP. It is a general purpose network "conversations" tool, designed for network testing. It can also be used for (very) quick setup of a server for a new protocol.
huPPPcol logs the start and end of a pppd (modem, isdn, pppoe dsl) session, and contains a program to analize the data. It was first developed to meet the hungarian telco standards, now it can be configured to other telcos as well. soon here...
The rPPP Suite is a Win32 client and a Linux server. The client is designed to look like Windows DUN, and interfaces with the server, which controls a PPP connection using WVdial. Useful for controlling a proxy server, where DOD is not an option.
ppplog keeps track of your ppp online session costs. It detects online/offline states and automatically calculates costs according to your local phone company. Simplicity and flexibility was key in development.
...It provides NAT, port-forwarding, spoofing list, blacklist of crackers and spywares sites, protection for tcp/udp scans, DOS/DDOS and Smurf attacks, TCP tuning, DHCP and PPP support and much more.
LANdialler allows workstations (Windows, Linux, etc.) on a LAN to control and share a modem attached to a Linux server. It is designed to be used with PPP and NAT on a Linux router to provide a home or small office with shared Internet access.
Microsoft RAS has some extensions which enables a windows client too negotiate a callback number (which can be set by the admin or user).
This project implements the same functionality for the PPP daemon en tries to keep up to date with the official re
This is a set of tools to manipulate the chap-secrets files, utilized by ppp to CHAP based authentication. It aims to be similar to these tools related with passwd, but manipulating the text based chap-secrets files.
Netmaster is a client/server program which allows the controlling of a network device over a lan. It was designed to allow users to easily bring a ppp device up/down, but it could be easily modified to do other simple tasks.
Shell daemon I made for maintaining my DSL up back in 2000. As of year 2006, there is probably a lot of good tools for monitoring and keeping alive your ADSL connection, like ddclient for DynDNS, and native Debian PPP management for example...
