Open Source Telnet Software

The Null-modem emulator (com0com) is a kernel-mode virtual serial port driver for Windows. You can create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. The HUB for communications (hub4com) allows to receive data and signals from one COM or TCP port, modify and send it to a number of other COM or TCP ports and vice versa.

TinTin++ is a console mud client for any type of text mud or bbs.

QuTTY is a multi-tabbed, multi-paned SSH/Telnet client with a terminal emulator. The goal is to support advanced features similar to iterm2. Just download and try it. If you see any issues you can install one of the Visual Studio runtimes VC++ 2012 or VC++ 2010. If you still face issues report it to us. Report any issues or feature-requests in issue-tracker. We need help from volunteers to find and fix any blocking issues, so that a stable release can be made soon.

This project is no longer maintained at SourceForge. Please see http://code.google.com/p/libcli for updates.

NetworkTools has 2 components: A protocol analyzer which plays a TCP client or server or pipeline, which sits between a client and server and shows how they communicate. A port scanner can scan a range of IP addresses and ports. See screenshots.

ICMP Shell (ISH) is a telnet-like protocol. It allows users to connect to a remote host and to open a shell using only ICMP to send and receive data. ICMP Shell was written in C for the UNIX environment.

Enables access to SSH Shell and File Transfer services using a web browser. Java Servlet application uses pure HTML to provide access to SSH services.

SBD is a way of leaving ultra-secure minimal access to a computer, which allows you to run a single command based on a one time key. It is good if you don't want to have an ssh server running all the time, but only want to start it when needed.

I'm a HW Support and used cacti, zabbix, but they are too "strong", sometimes I just want to know server "worked fine", and show me a basicly load-average chart, that's enough. And the other hand, I need run command (like: "top", "iostat", "date" etc.) remotely and show it out to the webpage. The hwmonitor(writen in C) is a simple daemon, you can define some command-name(like: show_top= top -b -n1), telnet to this daemon and input your def-command(like: show_top), hwmonitor will return the info. And hwclient(include in this project, writen in C) connect to hwmonitor, input a define command-name to get server load-average and IO-idle each 60 seconds(you can change it) into a text file. hwgraphic (include in this project, writen in PHP) read the text file(generated by hwclient) and show the load-average chart and IO-idle chart.

Cursed Menu aims to create an ncurses based menu system for character terminal sessions. This menu program could be used to create user, system administration, or utility menus for clients connecting with text based clients such as telnet, ssh, or rlogin

Pure object based operating environment, script language, shell, loads plugins to extend functionality, it's a MUD gone awry.

Get and display the traffic counter of a Fritz!Box 7270 (or similar) in a human readable form on local host. The telnet daemon has to be enabled on the FritzBox to download the data file from the AVM router to local host.

Home Server Download Daemon (HSDD) is free non-GUI download manager for home network servers written in Java. HSDD is controlled remotely by telnet protocol.

ISeeWhatYouAreDoing is a useful tool for getting screenshots and executing commands over Tcp/Ip or Ftp. Because it has NO security the Tcp/Ip part shouldn't be used in public networks (Use a firewall! :)). It was designed for easily keeping an eye on what people in your home network are doing and (if necessary) turn f.e. your brother's computer off when he forgot. As said it is able to work on very bad connections. Bin/Bin.zip is the basic package with client and a gui server, Bin/Hidden_Server.zip contains the "serious" version with a useful config.txt, no gui (server should run in background) and uses mainly ftp to get its commands, although you can connect via Tcp/Ip and the client from the Bin/Bin.zip or Bin/Client_Only.zip package. The hidden server has an English readme! For further information about the usage of the program please look at Doc/ or at the readmes in Bin.zip (currently both German, sorry). I hope v0.3.0 will follow till 12/12.

JBuzz BBS Server is a telnet daemon which provides several communication facilities, like discussion board and chatting room for clients to experience. In order to extend functions for the system more easily, the feature called "applet" is introduced.

The LanChat Messenger is a series of batch files that interatct together to form a system in which you can communicate with other machines on your network as long as the machine can map a network drive, execute batch files, and change files and folders. The Lanchat Messenger was inspired from another work of messaging, it was extremely simple and easy to use. My messenger works towards the same goals with the advantage of customizable features and adaptable windows.
