## Introduction
|
||||
|
||||
ceofhack is the first implementation of ***EOF*** (Eris Onion Forwarding),
|
||||
ceof is the implementation and documentation
|
||||
of ***EOF*** (Eris Onion Forwarding),
|
||||
the secure, peer-to-peer (p2p), decentralised anonymous chat network.

You can read the
|

[bachelor thesis](http://git.schottelius.org/?p=ceof;a=blob;f=doc/thesis.pdf),
|
||||
which describes the motivation and goals or you
|
||||
can view [the poster that was used on the presentation](http://git.schottelius.org/?p=ceof;a=blob;f=doc/appendix/poster.pdf).
|
||||
|
||||
## Get ceof
|
||||
|
||||
You can get ceof via git:
|
||||
|
||||
git clone git://git.schottelius.org/ceof

## Requirements
|
||||
|
||||
ceofhack depends on a small number of other packages:
|
||||
|
||||
* [gpgme](http://www.gnupg.org/gpgme.html)
|
||||
* make
|
||||
* [latex](http://www.latex-project.org/) and [dia](http://live.gnome.org/Dia)
|
||||
(for documentation)
|
||||
|
||||
## Building ceofhack
|
||||
|
||||
Simply run the following line:
|
||||
|
||||
cd ceofhack && make
|
||||
|
||||
Parallel building is also supported, like this:
|
||||
|
||||
cd ceofhack && make -j8

## Introduction
|
||||
|
||||
ceofhack and all other EOF subsystems need a common place to find themselves
|
||||
and to function properly.
|
||||
|
||||
## Initial configuration: the easy way
|
||||
|
||||
Simply run the following line:
|
||||
|
||||
cd ceofhack && ./scripts/init_home.sh
|
||||
|
||||
This will
|
||||
|
||||
* create a the configuration directory **$HOME/.ceof**,
|
||||
* create a new pgp key pair,
|
||||
* add the tcp transport protool
|
||||
* and enable the tcp transport protocol to listen to **0.0.0.0:4242**.
|
||||
|
||||
## Initial configuration: the expert way
|
||||
|
||||
Read and understand **./scripts/init_home.sh** and consult
|
||||
the current EOF standard document.

|

|
||||
To get into EOF through ceofhack, you should make sure you understand
|
||||
[[how to use|user]] ceofhack in general. Depeding on your skills and
|
||||
interests, you may either be interested in
|
||||
|
||||
* hacking the core (aka ceofhack, rare developers probably)
|
||||
* creating user interfaces (ui)
|
||||
* creating transport protocols (tp)
|
||||
|
||||
## API documentation
|
||||
|
||||
In general, everything you need should be documented in the
|
||||
EOF standard document. If it's not, it's probably a bug
|
||||
(in that case, send a patch).
|
||||
|
||||
## UI developers
|
||||
|
||||
UIs can either live in their own projects or be a part of
|
||||
ceofhack. The **first** way is recommended, so your development
|
||||
does not depend on ceofhack.
|
||||
|
||||
## Transport protocol developers
|
||||
|
||||
TPs can either live in their own projects or be a part of
|
||||
ceofhack. The **second** way is recommended, so all available
|
||||
transport protocols are shared with the ceofhack installation.
|
||||
|
||||
### Creating a new transport protocol
|
||||
|
||||
You can use the following code as a start:
|
||||
|
||||
scheme=phpbb
|
||||
implementation=shell
|
||||
cd ceofhack/tp
|
||||
mkdir -p ${scheme}/${implementation}
|
||||
echo "echo listening implementation" > ${scheme}/${implementation}/listen
|
||||
echo "echo send implementation" > ${scheme}/${implementation}/send
|
||||
chmod 0755 ${scheme}/${implementation}/*
|
||||
|
||||
Now you've a dummy "working" transport protocol.
|
||||
|
||||
### Enabling a new transport protocol
|
||||
|
||||
You can use the following code as a start:
|
||||
|
||||
scheme=phpbb
|
||||
implementation=shell
|
||||
cd ceofhack/tp
|
||||
|
||||
# Enable protocol in general
|
||||
mkdir -p "$HOME/.ceof/tp/available/${scheme}"
|
||||
cp "${scheme}/${implementation}/listen" "$HOME/.ceof/tp/available/${scheme}"
|
||||
cp "${scheme}/${implementation}/send" "$HOME/.ceof/tp/available/${scheme}"
|
||||
|
||||
# Enable listener for protocol
|
||||
address="describe-particular-address"
|
||||
mkdir -p "$HOME/.ceof/tp/listen/${scheme}-${address}"
|
||||
echo "${scheme}${address}" > "$HOME/.ceof/tp/listen/${scheme}-${address}/url"
|
||||
|
||||
### Submitting a transport protocol for inclusion into the mainline
|
||||
|
||||
* Create a branch ${scheme}-${implementation} on your side
|
||||
* Submit a pull request (via ML, IRC, github, whatever)

## How to get ceofhack running?
|
||||
|
||||
There are three simple steps to get ceofhack running:
|
||||
|
||||
* [[Get ceofhack|get]]
|
||||
* [[Build ceofhack|build]]
|
||||
* [[Configure ceofhack|configure]]
|
||||
|
||||
## How to use ceofhack?
|
||||
|
||||
ceofhack is only the main part of an EOF implementation.
|
||||
ceofhack itself is **not** a user interface (**ui**).
|
||||
There is, however, a sample command line user interface
|
||||
included, called **ui_cmd**. Thus, to make real use of
|
||||
ceofhack, you need to
|
||||
|
||||
* start ceofhack
|
||||
* and start a user interface
|
||||
|
||||
The following sections explain the ui_cmd user interface,
|
||||
but the principles are the same for other user interfaces.
|
||||
All the following examples assume that ceofhack is already
|
||||
running.
|
||||
|
||||
## How to chat with ceofhack?
|
||||
|
||||
As EOF is a p2p chat network, there's no central server. Thus, you need
|
||||
to specify where your chat partner ("peer" in EOF speak) can be found.
|
||||
In ui_cmd you do that with **ui_cmd_peer_add**:
|
||||
|
||||
./ui_cmd_peer_add telmich tcp:127.0.0.1:4242 A310FB220BA776083559C8276A8817C51B70A5DF
|
||||
|
||||
Where
|
||||
|
||||
* **telmich** is the nickname I gave that peer
|
||||
* **tcp:127.0.0.1:4242** is the initial address of that peer
|
||||
* **A310FB220BA776083559C8276A8817C51B70A5DF** is the pgp fingerprint
|
||||
|
||||
### Getting the fingerprints
|
||||
|
||||
You can retrieve all fingerprints known to EOF in a copy & past compatible
|
||||
format, if you run this command:
|
||||
|
||||
gpg --homedir $HOME/.ceof/gpg --fingerprint | sed 's/ //g'
|
||||
|
||||
### Getting keys
|
||||
|
||||
As the current protocol does not define a key exchange, you need
|
||||
to manually import pgp keys of other peers. You can do that by dowloading
|
||||
the public key of the peer to **peer.key** and then running
|
||||
|
||||
gpg --homedir $HOME/.ceof/gpg --import peer.key
|
||||
|
||||
### Exporting your key
|
||||
|
||||
To allow others to chat with you, you need to publish your public
|
||||
key somewhere. You can retrieve it the following way:
|
||||
|
||||
gpg --homedir $HOME/.ceof/gpg --export -a <yourkeyid> > mykey.key
|
||||
|
||||
### Sending a message
|
||||
|
||||
After you successfully added the new peer, you can drop her a message
|
||||
by issuing
|
||||
|
||||
./ui_cmd_peer_send telmich "What's up?"
|
||||
|
||||
### Displaying messages
|
||||
|
||||
ceofhack will always receive messages, independently of whether
|
||||
a user interface is connected or not. The user interface must
|
||||
take care of displaying them. The included ui support a generic
|
||||
listen command, which will display all incoming ui commands:
|
||||
|
||||
./ui_cmd_listen
|
||||
|
||||
And in addition, it will also show the messages received.
