netsck

netsck is a network utility tool which is developed to prototype or test network things. It provides a shell inside which runs javascript engine. Makes possible to create, bind, send data through or receive data from a socket. Currently only udp_socket is implemented.

• It is a terminal application.

• Depends on QtQml, QtNetwork and QtCore.

• Qt 5.12.8 and greater

• GCC 7.3.1 and greater

• Currently tested only on Linux but should work for Windows too.

Note that, netsck uses ansi color codes to colorize the terminal. On Windows, it is disabled by default so if you want 'netsck' to have a better look, you should enable virtual terminal with :

[HKEY_CURRENT_USER\Console]
"VirtualTerminalLevel"=dword:00000001

Documentation

In doc folder man pages and merged-pdf version of man pages exist.

Man pages are accessible from netsck in application, so just type help() to the console. On Linux, man pages are embedded. On Windows, netsck tells to the explorer.exe to open merged-pdf version.

Usage

Create udp echo server

var srv = new udp_socket()
srv.bind( AnyIPv4 , 10000 )
srv.enable_stdout( false )

while( wait_key( 30 ) != Key.ESC )
{
    srv.wait_a_bit()
    
    while ( srv.has_datagram() )
    {
        var dgram = srv.read_datagram()
        
        Hex.print( dgram.data )
        
        srv.send(
            dgram.data ,
            dgram.sender_addr ,
            dgram.sender_port
        )
    }
}

Create udp client

var cli = new udp_socket()

cli.send(
    "Hello, u there ?" ,
    "127.0.0.1" ,
    10000
)

cli.send(
    flat(
        [ 0x01 , 0x05 , 0x14 , ...beint32( 12345 ) , ...lefloat( 14.2 ) ]
    ) ,
    "127.0.0.1" ,
    10000
)
