Project Description

Develop a simple client-server system of remote backup

Client is made of command rcopy

Syntax to copy local file “[url removed, login to view]” to remote server “path” is
rcopy [url removed, login to view] server:path
where server is the name or the IP address of the server

file can be accesses via absolute or relative path

if in the specified path already exsists a file with the same name, the system must request if the user wants to overwrite it (like option -i of the cp command)

command rcopy accept the following parameters:
-r: recursive copy of the path specified as first argument (like -r of cp command)
-v: print on screen the file names while copying
-f: force the overrwrite if the destination file already exsists
--exclude=[url removed, login to view], file2.txt...exclude from the copy the file [url removed, login to view], file2.txt...

The request must run with credentials of the user who runs the server

Server must accept multiple connection with thread, and wait for incoming connection on TCP port 1234
File transfer must be on the TCP port 1235 or on the port 1234

On a single system must run multiple client

File access must be controlled by a lock system. A single thread at one time can access a file to write, multiple to read

System must work both under Linux and Windows

Linux server ask to client the authentication of the remote user

Linux server executes operation with the credentials of the client user

Software must be written in C
It consists of a single Client and server, compiled with conditional compiling
