I2P+ is an enhanced version of the Java I2P anonymizing network platform that aims to deliver a superior user experience and improved network performance while retaining full compatibility with upstream I2P.
An enhanced user interface with updated themes, easier to understand configuration and diagnostics, and an augmented feature set make I2P+ a compelling alternative to the official I2P release.
Additionally, I2P+ implements improvements to the router's network performance and, for routers that are firewalled, significantly increases participating traffic and network responsiveness. Performance of the resident BitTorrent client I2PSnark is also improved in some contexts.
The changes relate to user interaction and enhanced presentation of the console and webapps, in addition to network performance improvements, leaving the underyling crypto untouched, so it remains 100% compatible with I2P.
On the network, an I2P+ router will identify as a normal I2P router.
For a full list of download options, see the downloads section below.
If you're running a manually installed version of I2P from the Java installer (not a repo or .deb installed version), updating is as simple as dropping the i2pupdate.zip file into your I2P application folder and restarting the router.
Note: Do not extract the zip file, simply copy it to the I2P application folder and restart I2P... I2P will extract the zip automatically and update.
As of 0.9.46+, the full installation will enable
https:// access to the console by default; you will need to allow the (self-signed) certificate before you can access the router console.
To disable automatic redirection of the http:// version of the router console on :7657 to https:// on :7667, add the following line to your
router.config file located in your I2P+ settings directory:
The default location of the (non-repo installed) I2P application folder varies by operating system:
Program Files (x86)\i2p\
Note: On Windows, the Windows service to control I2P will be installed, for which you will require admininstrative privileges, and the service control shortcuts to stop and start the service may need to be run as an administrator to work.
An I2P-only torrent of the latest release update is also available.
To obtain release updates of I2P+, the recommended method is to add the I2P-only torrent url of the latest release to I2PSnark, and when downloaded, manually copy the
i2pupdate.zip file to your application folder. Restarting the router will activate the update process.
Note: After you have installed an I2P+ update, you may need to refresh your browser cache to ensure any updated css files and resources are loaded for the console and web apps. In Firefox and Chrome, CTRL+SHIFT+R will force the resources to be reloaded for the page you are viewing. You may also need to repeat the process for the console webapps (torrents, susimail, susidns etc).
It's also recommended to enable the Update with Unsigned Development builds option on the router updates page, and optionally replace the default release version url
http://skank.i2p/i2pupdate.zip with the development branch url
http://skank.i2p/dev/i2pupdate.zip if you want to subscribe to the rolling release builds.
Note: To avoid updating to vanilla I2P releases, set the Update Policy on the page to Notify only (if not already configured), and then you'll be notified in the console sidebar when an I2P+ update is available, with the option to download manually.
If you have installed I2P from a software repository, you will need to disable the I2P service and download the I2P+ Linux Java installer in order to run I2P+. You will benefit from access to official updates more speedily than those available in the repository, and you'll be able to install custom builds such as I2P+.
java -jar i2pinstall_1.7.0-0+_linux-only.jar(replace the i2pinstall filename with the file you downloaded, and change to the download directory before running the command). To run the installer headless (console install with no GUI):
java -jar i2pinstall_1.7.0-0+_linux-only.jar -console
sudo sed -i -e '/^assistive_technologies=/s/^/#/' /etc/java-*-openjdk/accessibility.properties
sudo chown -R yourusername:yourusername ~/.i2p/
sudo service i2p stop && sudo systemctl disable i2p
/bin/su yourusername -c "/home/yourusername/i2p/i2prouter start"to your /etc/rc.local file
~/i2p/i2prouter startto your session startup configuration tool
~/i2p/i2prouter install(note: you will need to uncomment the line
#RUN_AS_USER=in the file
~/i2p/i2prouterand add your login username to enable this feature).
Note: When installing I2P+ headlessly via the
-console argument, the installer will default to installing to the current working directory, so either create the desired installation directory first (usually
~/i2p/) and move the install.jar file into that directory before starting the installation, or manually specify the installation path when prompted.
I2P+ does not interfere in any way with the normal I2P update process. When a new official release is made available, you can easily restore your installation to vanilla I2P by installing the update.
If you'd like to try out I2P+ with the option to change back to your existing I2P installation, the easiest way is to make a copy of your I2P application folder, and then copy the update to the working I2P application folder and restart the router.
In the event that you wish to restore normal I2P, shutdown I2P+ and then restore the backup after renaming/deleting the working I2P app folder. This will ensure that your official I2P installation will be exactly as you left it!
I2P+ is now available on Gitlab. If you have modifications to the codebase you'd like to see included in I2P+, fork the code and modify the files you wish to submit, and then create a merge request.
If you wish to avoid having to manually resolve the new I2P domains linked in I2P+ with jump links, you can add
http://skank.i2p/hosts.txt to your Subscriptions list in your I2P Addressbook. This is a small, curated list of links that have been added to the Router Console in I2P+. You can alternatively import the hosts.txt file into SusiDNS via the Import function.
If you wish to promote I2P+ to other users who may not have the skank.i2p domain in their addressbook, you can share the helper link.

Note: Occasionally I2P+ development builds will be uploaded to the release channel prior to an official release when significant bugs that may impact network performance are fixed or mitigated; see this upstream patch for an example of a sufficiently serious issue that merits a pre-release.
