## What is I2P?
|
|
|
|
I2P (Invisible Internet Protocol) is a universal anonymous network layer.
|
|
All communications over I2P are anonymous and end-to-end encrypted, participants
|
|
don't reveal their real IP addresses.
|
|
|
|
I2P client is a software used for building and using anonymous I2P
|
|
networks. Such networks are commonly used for anonymous peer-to-peer
|
|
applications (filesharing, cryptocurrencies) and anonymous client-server
|
|
applications (websites, instant messengers, chat-servers).
|
|
|
|
I2P allows people from all around the world to communicate and share information
|
|
without restrictions.
|
|
|
|
A deeper technical introduction of I2P can be found [here](https://geti2p.net/en/docs/how/tech-intro).
|
|
|
|
## How i2pd differs from original I2P implementation?
|
|
|
|
While [Java I2P](https://geti2p.net) and i2pd are both clients for the I2P network, i2pd has some big differences and advantages:
|
|
|
|
* Java I2P has built-in applications for torrents, e-mail and so on. i2pd is just a router which you can use with other software through I2CP interface.
|
|
* i2pd does not require Java. It's written in C++.
|
|
* i2pd consumes less memory and CPU.
|
|
* i2pd can be compiled everywhere gcc or clang presented (including Raspberry and routers).
|
|
* i2pd has some major optimizations for faster cryptography which leads to less consumption of processor time and energy.
|
|
|
|
## Why is the I2P network so slow and unstable sometimes?
|
|
|
|
By design, in the I2P network, your connection gets encrypted through a chain of 6
|
|
random computers in the way to its final destination. If one of those computers
|
|
is shut down, or experiences connectivity problems, it can take some time for your
|
|
I2P router to discover and fix that issue.
|
|
|
|
## Help! i2pd is not working. What do I do?
|
|
|
|
First of all, synchronize system clock on your machine with Internet.
|
|
|
|
If that does not help, on Linux machines, check the number of open file descriptors
|
|
allowed to a process. In a terminal, run:
|
|
|
|
ulimit -n
|
|
|
|
Correct value for regular i2pd node is 4096, for a floodfill it is 8192.
|
|
Set it before you run i2pd like so:
|
|
|
|
ulimit -n 4096 && ./i2pd
|
|
|
|
If that doesn't help, then you may have found a bug.
|
|
Contact developers with IRC or create an issue on GitHub.
|
|
|
|
## What is good tunnel creation success rate value?
|
|
|
|
\>10%. Larger is better.
|
|
|
|
## Is there a place I can use to find running I2P websites?
|
|
|
|
Sure, there is a list [here](http://identiguy.i2p.xyz/)
|
|
|
|
## How can I better integrate my router to the network?
|
|
|
|
Edit your settings: set correct bandwidth and share rate.
|
|
|
|
Run i2pd for a long time, download and seed some popular torrents.
|
|
|
|
## What browser should I use to browse I2P websites?
|
|
|
|
Use any open source browser - for example, Firefox or a Chromium based alternative. Create separate profile for I2P ([firefox instructions](https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles)),
|
|
and try not to mix clearnet browsing with I2P. Learn how to configure your browser for better privacy and security.
|
|
|
|
Configuring [privoxy](https://wiki.archlinux.org/index.php/Privoxy) for I2P/onion/clearnet browsing at the same time is a good idea.
|
|
|
|
i2pd's socks proxy has an option to pass all non-I2P traffic to the Tor socks proxy. Make sure you know what are you doing when using this!
|
|
|
|
## What is a floodfill mode?
|
|
|
|
Floodfill mode make your router a floodfill, that means what other routers will publish and get LeaseSets and RIs on your router. [Read more](http://geti2p.net/en/docs/how/network-database).
|
|
Floodfill mode require more bandwith, CPU time. You can enable floodfill only if it has public ipv4 address and minimal bandwidth O: `floodfill = true`
|
|
|
|
## How is I2P different from Tor?
|
|
|
|
I2P and Tor have some similarities, but they are completely different technologies.
|
|
|
|
Tor is designed to act as an anonymous proxy for the regular Internet, and I2P
|
|
is specifically designed to make a virtual anonymous network for hidden services
|
|
and p2p applications.
|
|
|
|
Tor Project was started by the US military and receives most of its funds
|
|
from the government, while I2P was started by a community of independent civilians.
|
|
|
|
Tor is highly centralized by design, while I2P is designed to be decentralized and distributed.
|
|
|
|
## Can use i2pd as a proxy for regular Internet?
|
|
|
|
Yes, but better use [Tor](https://www.torproject.org/) for that.
