# BitTorrent
[BitTorrent](https://www.bittorrent.org/) is a communication protocol for peer-to-peer file sharing (P2P), which enables users to distribute data and electronic files over the Internet in a decentralized manner.
Users on the BitTorrent Network are not anonymous, because everyones IP address is known. To torrent anonymously one can use the [I2P](I2P.md) Network with i2psnark.

# File Transfer Protocol
The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control (Port `21`) and data (Port `20`) connections between the client and the server. FTP users may authenticate themselves with a plain-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with [SSH](../applications/SSH.md) File Transfer Protocol (SFTP). One popular FTP client is [FileZilla](../applications/network/FileZilla.md).

# I2P Network
I2P is an anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties. Many applications are available that interface with I2P, including mail, peer-peer, IRC chat, and others. Anonymous [Torrenting](../internet/BitTorrent.md) via i2psnark is also possible.
## Usage
Install `i2pd` (deamon written in C++) and enable the service. Router Interface is at `127.0.0.1:7070` with [HTTP](../internet/HTTP.md) Proxy at `127.0.0.1:4444`
## Configuration
There are two separate config files: `i2pd.conf` and `tunnels.conf`. `i2pd.conf` is the main configuration file, where you configure all options. `tunnels.conf` is the tunnel configuration file, where you configure I2P hidden services and client tunnels.
Example `i2pd.conf`:
```ini
logfile = /var/log/i2pd/i2pd.log
ipv4 = true
ipv6 = false
ssu = true
bandwidth = X
[ssu2]
enabled = true
published = true
[http]
enabled = true
address = 0.0.0.0
port = 7070
auth = true
user = i2pd

# Purokishi
outproxy = http://purokishi.i2p
[socksproxy]
address = 0.0.0.0
port = 4447
[sam]
enabled = true
address = 127.0.0.1
port = 7656
[i2cp]

# Tailwind CSS
Tailwind CSS is a utility-first CSS framework that provides a set of low-level utility classes to build designs directly in your markup. It's a highly customizable and efficient way to create modern, responsive user interfaces.
## Setup
To use TailwindCSS include this in your documents header:
```html
<script src="https://cdn.tailwindcss.com"></script>
```
## Modifiers
You can modify when a utility class will become active by using `mod:` before the class name.
Some modifiers include:
- `hover`
- `focus`
- `active`
- `disabled`
- `invalid`
- `first`
- `last`
- `even`
- `odd`
This modifier is used for dark mode:
- `dark`
These modifers are used for device orientation:
- `landscape`
- `portrait`
These modifers are used for responsive design and reresent their respective screen sizes when a class will become active:
- `sm`
- `md`
- `lg`
- `xl`
- `2xl`
For a list of all classes see the [documentation](https://tailwindcss.com/docs).

# The Onion Router (TOR)
The Tor Project (The onion routing) is an open source implementation of onion routing that provides free access to an anonymous proxy network. Its primary goal is to enable online anonymity by protecting against traffic analysis attacks.
Users of the Tor network run an onion proxy software on their machines, which presents a SOCKS interface to its clients. This software connects out to Tor, periodically negotiating a virtual circuit through the Tor network. Tor employs cryptography in a layered manner (hence the 'onion' analogy), ensuring forward secrecy between routers.
As an overlay network it is similiar to [i2p](../internet/I2P.md).
## Usage
Start/enable `tor.service`. Alternatively, launch it with `sudo -u tor /usr/bin/tor`.
To use a program over Tor, configure it to use `127.0.0.1` or `localhost` as a SOCKS5 proxy, with port `9050` for plain Tor with standard settings.
The proxy supports remote DNS resolution: use `socks5**h**://localhost:9050` for DNS resolution from the exit node (instead of `socks5` for a local DNS resolution).
## Configuration
Tor reads its configurations from the file `/etc/tor/torrc` by default, or if the latter is not found, from `$HOME/.torrc`. The configuration options are explained on the [Tor website](https://torproject.org/docs/tor-manual.html.en). The default configuration should work fine for most Tor users.
## Hidden Services
Hidden Services are web services behind an onion domain.
To generate onion domains [mkp224o](https://git.hydrar.de/utilities/mkp224o) can be used.
To enable a hidden service add this to `torrc`:
```
HiddenServiceDir /var/lib/tor/hidden_service/
HiddenServicePort 80 127.0.0.1:80
```

# WebDAV
WebDAV (Web Distributed Authoring and Versioning) is an extension of [HTTP](../internet/HTTP.md)/1.1 and therefore can be considered to be a protocol. It contains a set of concepts and accompanying extension methods to allow read and write across the [HTTP](../internet/HTTP.md)/1.1 protocol. Instead of using NFS or [SMB](../applications/web/Samba.md), WebDAV offers file transfers via [HTTP](../internet/HTTP.md). A hosting application with WebDAV support is [dufs](../applications/web/dufs.md).
