Light network utility

This is a simple cli win-socket utility. It was created for educational purpose and for some practice with C and network-programming. If you have any comments about this project (technical remarks, code quality, etc.) -> contact me via email, I'll be glad to discuss them.

What can it do?

• Share files using IPv4 (IPv6) + TCP. !!!DEPRECATED!!!
• Tracert and ping

Tracert and ping

CLI arguments for ping:

light-netw -t p -a host.com

And it will ping host.com with 4 icmp packets.

CLI arguments for tracert:

light-netw -t tr -a host.com -i 30

And it will tracert host.com with 30 hops as max.

About files sharing !!!DEPRECATED!!!

There are two modes : server and client.

You can run utility in server mode and spec a dir for it. Then in client mode can request any file from this dir and the server will response with it.

Options

FLAG	Meaning	DEFAULT
-a	Address (domain or IP)
-p	Port	3490
-t	Run type: sd (server dirshare), cf (client file)
-i	Input path, dir for server, file name for client
-o	Output path, output file for client
-r	Routing protocol, v4 for IPv4, v6 for IPv6	v4
-l	Path to file for logs	light-netw.logs.log

Examples

You can run the server:

light-netw -t sd -r v6 -i path\to\dir

And the client:

light-netw -t cf -r v6 -a localhost -i folder\file.txt -o path\to\some_file.txt

The server will:

1. get "folder\file.txt" from client via IPv6 and port 3490
2. try to find file path\to\dir\folder\file.txt
3. send it to the client, if it exists, and error code otherwise

The client will:

• write it to path\to\some_file.txt
