A full-featured C++ implementation of the I2P router


i2pd - Full-featured C++ implementation of I2P client.


i2pd [OPTION1] [OPTION2]...


i2pd is a C++ implementation of the router for the I2P anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties.
Any of the configuration options below can be used in the DAEMON_ARGS variable in /etc/default/i2pd.


--help Show available options.
--conf= Config file (default: ~/.i2pd/i2pd.conf or /var/lib/i2pd/i2pd.conf) This parameter will be silently ignored if the specified config file does not exist. Options specified on the command line take precedence over those in the config file.
Tunnels config file (default: ~/.i2pd/tunnels.conf or /var/lib/i2pd/tunnels.conf)
Where to write pidfile (don't write by default)
--log= Logs destination: stdout, file, syslog (stdout if not set, file - otherwise, for compatibility)
Path to logfile (default - autodetect)
Log messages above this level (debug, info, warn, error, none)
Log messages with full CLF-formatted date and time (disabled by default)
Path to storage of i2pd data (RI, keys, peer profiles, ...)
Path to tunnels configuration files (default: ~/.i2pd/tunnels.d or /var/lib/i2pd/tunnels.d)
--host= The external IP address
--port= The port to listen on for incoming connections
The network interface to bind to
The network interface to bind to for IPv4 connections
The network interface to bind to for IPv6 connections
--ipv4= Enable communication through ipv6 (enabled by default)
--ipv6 Enable communication through ipv6 (disabled by default)
--ntcp= Enable usage of NTCP transport (enabled by default)
Set proxy URL for NTCP transport
--ssu= Enable usage of SSU transport (enabled by default)
Router will not accept transit tunnels at startup (disabled by default)
Router will be floodfill (disabled by default)
Bandwidth limit: integer in KBps or letter aliases: L (32KBps), O (256), P (2048), X (>9000)
Limit of transit traffic from max bandwidth in percents. (default: 100)
Router will go to background after start (disabled by default)
Router will use system folders like /var/lib/i2pd (disabled by default)
Name of a family, router belongs to.
Switches, which enabled by default (like --ssu, --ntcp, etc.), can be disabled in config file. See service-specific parameters in example config file /usr/share/doc/i2pd/i2p


/etc/i2pd/i2pd.conf, /etc/i2pd/tunnels.conf, /etc/default/i2pd
i2pd configuration files (when running as a system service)
i2pd profile directory (when running as a system service, see --service above)
