Coffer

About

Easily send and receive files in your LAN. Without ever typing an IP address.

How does it work

Basically, it's an HTTP server with simple APIs + zeroconf

How to use it

coffer send filename
coffer get --all

Other features

• You can filter what to download with --filter
• You can automatically exit after every file has been downloaded once, using --one
• You can have passwords (but they are not a great form of protection!)

Non-features

• This kind of sharing is not secure, is not anonymous, and won't be. Making it easy means announcing our service (not anonymous, therefore) and making it simple means allowing anyone to download (making it unsecure by definition)

Known bugs

• File download is still not implemented

Installation

pip install coffer is enough

Real-life examples

one to one

Scenario1: You are in a room with another person. Each one has a computer. You are in the same LAN. You want to send a file to a person in front of you. This usually requires:

• manually launching a server to share files
• spelling the URL to the fellow in front of you, who has to type it

That's too boring.

solution

coffer send --one myfile.txt
coffer get --all

one to many

You are in a room with many people. Each one has a computer. You are in the same LAN. You want to send a file to many people. This usually requires:

• creating a directory with only the files you want to share inside
• manually launching a server to share files
• spelling the URL to everyone, and everyone needs to type it.

This is crazy.

solution

coffer send myfile.txt
coffer get --all

many to many + a command

You are in a room with many people. Each one has a computer. You are in the same LAN. Everyone wants to send his gpg key to everyone else. This usually requires:

• each one creating a directory with only the files you want to share inside
• each one manually launching a server to share files
• each one spelling the URL to everyone.
• each one following each link and gpg --import it

Are you kidding me?

solution

coffer send =(gpg -a --export $(gpg --with-colons -K|egrep '^sec'|cut -d: -f 5|head -n1))
coffer get --all --cat | gpg --import

About the name

The main concept in coffer is that you are offering files to other people. Sharing is caring, and I like it. The other thing that I like so much is coffee. coffer is the sum of the best things in life.
