## 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.
|
|
|
|
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) is being original client for 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.
|
|
|
|
## What can I use i2pd for?
|
|
|
|
i2pd can be used to organize anonymous network layer for any of your applications.
|
|
|
|
You can run websites, create public and private chat chatrooms, use instant
|
|
messaging and E-Mail, share files -- do everything with strong privacy and
|
|
security layer.
|
|
|
|
## Why is network so slow and unstable sometimes?
|
|
|
|
Because it's secure design, your network connection goes encrypted through a chain of 6
|
|
random computers in the way to it's final destination. If one of those computers
|
|
is shut down, or experiences connectivity problems -- it can take some time for
|
|
I2P router to discover and fix that issue.
|
|
|
|
## Help! i2pd is not working. What to 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 proccess. Run:
|
|
|
|
ulimit -n
|
|
|
|
Correct value for regular i2pd node is 4096, for a floodfill it is 8192.
|
|
Set it before you run i2pd like that:
|
|
|
|
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?
|
|
|
|
Average values are 15% - 40%. Larger is better.
|
|
|
|
## Are there any alive I2P websites?
|
|
|
|
Sure, there is a list of alive websites [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 opensource browser - for example, Firefox or Chromium based. Create separate profile for I2P ([firefox instructions](https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles)), try not to mix clearnet browsing with I2P. Learn how to configure your browser for better privacy and security.
|
|
|
|
Good idea is to configure [privoxy](https://wiki.archlinux.org/index.php/Privoxy) for I2P/onion/clearnet browsing at the same time.
|
|
|
|
i2pd socks proxy has an option to pass all non-i2p traffic to Tor socks proxy. Make sure you know what are you doing!
|
|
|
|
## What is a floodfill mode?
|
|
|
|
Floodfill mode is a special mode, which contributes to I2P network more.
|
|
You may want to enable floodfill mode if you have stable uptime and high bandwidth
|
|
to share.
|
|
|
|
## How is I2P different from Tor?
|
|
|
|
I2P and Tor has some similarities, but they are completely different in every way possible.
|
|
|
|
Tor is designed to act as anonymous proxy for the regular Internet, I2P is
|
|
designed to create anonymous network layer with its own private resources.
|
|
|
|
Tor Project was started by US military and has a long history of recieving funds
|
|
from the government, while I2P was started by community of independent civilians.
|
|
|
|
Tor is highly centralized by design, while I2P is decentralized and distributed.
|
|
|
|
## Can use i2pd as a proxy for regular Internet?
|
|
|
|
Not out of the box. You better use [Tor](https://www.torproject.org/) for that.
