Building: The i2p package will be installed in /opt/i2p If you want to change installation dir, change the variable INSTALL_DIR on i2p.SlackBuild and rebuild the package. You will also need to do the same in the base-i2p package. Installation and Upgrade: Probably you will never have to update i2p packages with upgradepkg, just because I2P has an auto-update function. However using upgradepkg lowers the demand on the I2P network as a whole, and is by far faster. After installpkg command, doinst.sh will execute a postinstallation script needed by I2P. Be sure to also install the base-i2p package. Optional: chmod +x /etc/rc.d/rc.i2p only if you want it to start on boot and stop on shutdown. How to start I2P: Start I2P service with- sh /etc/rc.d/rc.i2p start Now tell your browser to user this proxy: localhost on port 4444 and open this page: http://localhost:7657/index.jsp Here you can configure I2P, watch network status and navigate anonimously.
