GNUs set of CLI utilities for basic Internet stuff.

I use ftp as a quick way to transfer stuff to my 3DS (games, Amiibo, …). On the 3DS you can set up a temporary server with ftpd.

• ftp to start ftp's shell, or give it the server IP and port to connect to ftp [ip] [port].
• From there can use standard Linux commands like ls, cd, …
• To upload send [filename].
• To download get [filename].
