This project was coded for networking course at Warsaw University (Faculty of Mathematics, Informatics and Mechanics).
It's purpose was to design and implement simple telnet server serving basic menu with selectable options.
To build the source please enter the following sequence of commands to your terminal:
$ cd <main_folder_of_telnetish>$ mkdir build && cd build$ cmake ..$ make
The make command should generatetelnet_server binary.
The server usage looks like follows:
./telnet_server server <port> [flags]
Where there exist the following flags:
| Switch | Description |
|---|
--local
Alias:-l | Run the server in local mode. In that mode server is not really a server
but a local program that runs the implemented ncurses app in your terminal. |
--nosplash | Disable initial splash screen animation |
--nocolors
Alias:-nc | Disable any ANSI color sequences |
--verbose
Alias:-v | Verbosive output mode |
telnetish |- include (telnetish header files) |- src (telnetish implemnetations of header files functions) \- server (server entrypoint and ncurses application)
The implementation is a bit unusual.
The telnet server itself is implemented inserver/server.cpp usinginclude/telnet-server.h andinclude/stimple-telnet-server.h.
The basic idea is that the clients connects to the server synchronically (each client is served after the current one quits application,disconnects or is timed out).
The server (seeinclude/term-program.h) forks itself and asynchronically runs ncurses applciation (seesrc/renderer.h).
The input and output is transferred from client to the forked process via pipes (and vice-versa).
It enables us to support any terminal type that is supported by ncurses and easilly implement console application via ncurses popular library.
Additionally the server can be started with--local switch to run as normal ncurses application without any network communication (useful whenyou want to locally test your application).
