Getting Started

In addition to the I2P download, you need to install Java if you do not have it already installed. I2P requires Java Runtime Version 7 or higher. (Oracle, OpenJDK, or IcedTea Java Version 7 or 8 recommended, except Raspberry Pi: OpenJDK 9 for ARM, PowerPC: IBM Java SE 7 or 8)
Determine your installed Java version here or type java -version at your command prompt.

Windows: Java 8 is recommended. Java 9 or higher may not work.

リリースノート

Pick your I2P Bundle

When you download the I2P software bundle, you get everything you need to connect and start participating in the I2P network and community. It even includes basic applications for every user, like e-mail, bittorrent, and a basic I2P site for you to personalize and share.

After you've installed, a set up wizard will help you configure a few important things like how much bandwidth you would like to share while your router begins to make connections to the network. After the set up wizard is complete, you will be directed to the console home page where you can access the rest of the applications or configure, monitor, or troubleshoot your I2P connections.

The most reliable way to launch the installer is from a terminal like this: java -jar i2pinstall_0.9.48.jar. This will launch the GUI installer. Depending on how your computer is set up, you may be able to start the installer by double-clicking the "i2pinstall_0.9.48.jar" file or right-clicking the file and selecting "Open with Java". Unfortunately, this behaviour is difficult to predict.

コマンドライン (UIなし) インストール:

I2P can also be installed in a terminal environment, which may be especially useful for servers, containers, or certain virtual machines. If you wish to use the installer without a GUI, you can use the command java -jar i2pinstall_0.9.48.jar -console to follow the install procedure in your terminal.

Debian / Ubuntu

I2P is available in the official repositories for Ubuntu Bionic and later, and Debian Buster and Sid. However, Debian Buster and Ubuntu Bionic (LTS) distributions will have older I2P versions. If you are not running Debian Sid or the latest Ubuntu release, use our Debian repo or Launchpad PPA to ensure you're running the latest I2P version.

Requires Android 4.0 (Ice Cream Sandwich) or higher. If you earlier installed I2P, unfortunately this release fixes some IPC issues which will force you to uninstall your current installation before installing this. 512 MB RAM 最低限; 1 GB 推奨。 The releases are not compatible with eachother, as they have different signatures. Uninstall them completely before installing any other version. The apk's from download.i2p2.de are signed by idk.

自動アップデート

0.7.5以降を起動している場合、ルーターが新リリースを検出するはずです。アップグレードするには、表示時にただルーターコンソールの「アップデートをダウンロード」ボタンをクリックするだけで構いません。

0.9.23まではいくつかのリリースは署名がルーターの中に存在するstr4dによって署名されていました。 0.9.9からはそれ以前の古いルーターがstr4dによって署名されたアップデートの検証に失敗するでしょう。 そのため以下の手順を用いて手動でアップデートする必要があります。

手動アップデート
4dac576536b4eaff5b4e8ff0e49d42bb2ff5167f6ead680b751c1bd2df7336c1
  1. Download the file to your I2P installation directory and rename as i2pupdate.zip. (alternately, you can get the source as above and run "ant updater", then copy the resulting i2pupdate.zip to your I2P installation directory). You do NOT need to unzip the file.
  2. 「再起動」をクリック
  3. コーヒーでも飲んで、11分後戻ってきてください
