A FTP client and server implementation
Clone with the --recurse-submodules to download dependencies and run
make
./client host [[ port=8080 ] -v | --help]
Once connected, the client can retrive local files and send them over TCP to the server, or request remote files from the server and save them locally.
The following commands are supported
| index | names | arguments | descriptions |
|---|---|---|---|
| n/a | help | print a help message | |
| 0 | quit, exit | exit the program | |
| 1 | ls | [ path ] | list files |
| 2 | cd | [ path ] | change directory |
| 3 | pwd | print present working directory | |
| 4 | get | remote_path [ local_path ] | download a file from the server |
| 5 | put | local_path [ remote_path ] | upload a file to the server |

| 7 | mkdir | path | create a directory on the server |
./server [[[ host=0.0.0.0 ] port=8080 ] -v | --help]
The server listens for TCP connections and handles clients concurently in separate processes. Each of these processes listens and executes commands sent by the client over TCP.
Uploaded files are put in a ./.ftp_data directory.
The protocol is the set of actions recognized by the client and server.
