Network Privacy Configuration

The mentioned packages and applications here are recommended to get provided on every fresh installed operating system for many security reasons as follows:

 

OpenNTPD: a Unix daemon implementing the Network Time Protocol to synchronize the local clock of a computer system with remote NTP servers. It is also able to act as an NTP server to NTP-compatible clients.

 

OpenSSH: a suite of secure networking utilities based on the Secure Shell protocol, which provides a secure channel over an unsecured network in a client–server architecture.

 

OpenSMTPD: a Unix daemon implementing the Simple Mail Transfer Protocol to deliver messages on a local machine or to relay them to other SMTP servers.

 

OpenDNSSEC: a complete DNSSEC zone signing system which is very easy to use with stability and security in mind. There are a lot of details in signing zone files with DNSSEC and OpenDNSSEC covers most of it.

 

OpenSSL: a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites.

 

OpenVPN: an open-source commercial software that implements virtual private network techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange.

 

OpenConnect: an open-source software application for connecting to virtual private networks, which implement secure point-to-point connections. It was originally written as an open-source replacement for Cisco's proprietary AnyConnect SSL VPN client, which is supported by several Cisco routers.

 

Stunnel: an open-source multi-platform application used to provide a universal TLS/SSL tunneling service. Stunnel can be used to provide secure encrypted connections for clients or servers that do not speak TLS or SSL natively.

 

SCdaemon: GnuPG is GNU's tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures. It includes an advanced key management facility and is compliant with the proposed OpenPGP Internet standard as described in RFC4880.

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.

 

I2pd: (I2P Daemon) is a full-featured C++ implementation of I2P client.

Installing i2p i2pd

i2p_enable="YES" >> /etc/rc.conf (FreeBSD)

i2p_user="i2p" >> /etc/rc.conf (FreeBSD)

 

You may need to enable the network in KDE System Settings > Network Settings > Use manually specified proxy configuration >> Exceptions 127.0.0.1, localhost

KDE System Settings > Network Settings > Use Manually Specified Proxy Configuration > HTTP – SSL - FTP Proxy >> IP 127.0.0.1, Port 4444 (This will be Connected via I2P)

To work with Privoxy add the following line to the Privoxy configuration file: forward .i2p localhost:4444

Outproxy Terms Of Service

Remember: I2P was not designed for creating proxies to the outer Internet. Instead, it is meant to be used as an internal network.

 

The I2P project itself does not run any proxies to the Internet. The only outproxy is a service from the privacy solutions project. Consider donating to them for a continued stable service. Increased funding will allow them to improve this service.

 

http://privacysolutions.no

 

By default, I2P comes with two outproxies configured: false.i2p and outproxy-tor.meeh.i2p. Even the domain names are different, it's the same outproxy you hit. (multi-homed/keyed for better performance)

 

Filtering is active on these outproxies (for example, mibbit and torrent tracker access is blocked). Eepsites that are accessible via .i2p addresses are also not allowed via the outproxies. As a convenience, the outproxy blocks ad servers.

 

Tor is a good application to use as an outproxy to the Internet.

 

TOR VS I2P

Comparison of Tor and I2P anonymizing proxy networks:

 

Tor - Onion Routing

Tor and Onion Routing are both anonymizing proxy networks, allowing people to tunnel out through their low latency mix network. The two primary differences between Tor / Onion-Routing and I2P are again related to differences in the threat model and the out-proxy design (though Tor supports hidden services as well). In addition, Tor takes the directory-based approach - providing a centralized point to manage the overall 'view' of the network, as well as gather and report statistics, as opposed to I2P's distributed network database and peer selection.

 

The I2P/Tor outproxy functionality does have a few substantial weaknesses against certain attackers - once the communication leaves the mixnet, global passive adversaries can more easily mount traffic analysis. In addition, the outproxies have access to the cleartext of the data transferred in both directions, and outproxies are prone to abuse, along with all of the other security issues we've come to know and love with normal Internet traffic.

 

However, many people don't need to worry about those situations, as they are outside their threat model. It is, also, outside I2P's (formal) functional scope (if people want to build outproxy functionality on top of an anonymous communication layer, they can). In fact, some I2P users currently take advantage of Tor to outproxy.

 

Comparison of Tor and I2P Terminology

While Tor and I2P are similar in many ways, much of the terminology is different.

 

Tor network I2P network
Cell Message
Client Router or Client
Circuit Tunnel
Directory NetDb
Directory Server Floodfill Router
Entry Guards Fast Peers
Entry Node Inproxy
Exit Node Outproxy
Hidden Service Hidden Service, Eepsite or Destination
Hidden Service Descriptor LeaseSet
Introduction point Inbound Gateway
Node Router
Onion Proxy I2PTunnel Client (more or less)
Onion Service Hidden Service, Eepsite or Destination
Relay Router
Rendezvous Point somewhat like Inbound Gateway + Outbound Endpoint
Router Descriptor RouterInfo
Server Router

 

Benefits of Tor over I2P

  • Much bigger user base; much more visibility in the academic and hacker communities; benefits from formal studies of anonymity, resistance, and performance; has a non-anonymous, visible, university-based leader
  • Has already solved some scaling issues I2P has yet to address
  • Has significant funding
  • Has more developers, including several that are funded
  • More resistant to state-level blocking due to TLS transport layer and bridges (I2P has proposals for "full restricted routes" but these are not yet implemented)
  • Big enough that it has had to adapt to blocking and DOS attempts
  • Designed and optimized for exit traffic, with a large number of exit nodes
  • Better documentation, has formal papers and specifications, better website, many more translations
  • More efficient with memory usage
  • Tor client nodes have very low bandwidth overhead
  • Centralized control reduces the complexity at each node and can efficiently address Sybil attacks
  • A core of high capacity nodes provides higher throughput and lower latency

 

Benefits of I2P over Tor

  • Designed and optimized for hidden services, which are much faster than in Tor
  • Fully distributed and self organizing
  • Peers are selected by continuously profiling and ranking performance, rather than trusting claimed capacity
  • Floodfill peers ("directory servers") are varying and untrusted, rather than hardcoded
  • Small enough that it hasn't been blocked or DOSed much, or at all
  • Peer-to-peer friendly
  • Packet switched instead of circuit switched
    • implicit transparent load balancing of messages across multiple peers, rather than a single path
    • resilience vs. failures by running multiple tunnels in parallel, plus rotating tunnels
    • scale each client's connections at O(1) instead of O(N) (Alice has e.g. 2 inbound tunnels that are used by all of the peers Alice is talking with, rather than a circuit for each)
  • Unidirectional tunnels instead of bidirectional circuits, doubling the number of nodes a peer has to compromise to get the same information. Counter-arguments and further discussion here.
  • Protection against detecting client activity, even when an attacker is participating in the tunnel, as tunnels are used for more than simply passing end to end messages (e.g. netDb, tunnel management, tunnel testing)
  • Tunnels in I2P are short lived, decreasing the number of samples that an attacker can use to mount an active attack with, unlike circuits in Tor, which are typically long lived.
  • I2P APIs are designed specifically for anonymity and security, while SOCKS is designed for functionality.
  • Essentially all peers participate in routing for others
  • The bandwidth overhead of being a full peer is low, while in Tor, while client nodes don't require much bandwidth, they don't fully participate in the mixnet.
  • Integrated automatic update mechanism
  • Both TCP and UDP transports
