I2P router written in C++

This project is licensed under the BSD 3-clause license, which can be found in the file LICENSE in the root of the project source code.

GCC 4.6 or newer, Boost 1.46 or newer, crypto++. Clang can be used instead of GCC.

VS2013 (known to work with 12.0.21005.1 or newer), Boost 1.46 or newer, crypto++ 5.62. See Win32/README-Build.txt for instructions on how to build i2pd and its dependencies.

• Linux x64 -
• Linux ARM - To be added
• Mac OS X - Got it working, but not well tested. (Only works with clang, not GCC.)
• Microsoft VC13 - To be added

First, build it.

On Ubuntu/Debian based

• sudo apt-get install libboost-dev libboost-filesystem-dev libboost-program-options-dev libboost-regex-dev libcrypto++-dev libboost-date-time-dev
• $ cd i2pd
• $ make

Then, run it:

$ ./i2p

The client should now reseed by itself.

To visit an I2P page, you need to find the b32 address of your destination. After that, go to the webconsole and add it behind the url. (Remove http:// from the address)

This should resulting in for example: http://localhost:7070/4oes3rlgrpbkmzv4lqcfili23h3cvpwslqcfjlk6vvguxyggspwa.b32.i2p

• --host= - The external IP (deprecated).
• --port= - The port to listen on
• --httpport= - The http port to listen on
• --log= - Enable or disable logging to file. 1 for yes, 0 for no.
• --daemon= - Enable or disable daemon mode. 1 for yes, 0 for no.
• --service= - 1 if uses system folders (/var/run/i2pd.pid, /var/log/i2pd.log, /var/lib/i2pd).
• --v6= - 1 if supports communication through ipv6, off by default
• --floodfill= - 1 if router is floodfill, off by default
• --bandwidth= - L if bandwidth is limited to 32Kbs/sec, O if not. Always O if floodfill, otherwise L by default.
• --httpproxyport= - The port to listen on (HTTP Proxy)
• --socksproxyport= - The port to listen on (SOCKS Proxy)
• --proxykeys= - optional keys file for proxy's local destination
• --ircport= - The local port of IRC tunnel to listen on. 6668 by default
• --ircdest= - I2P destination address of IRC server. For example irc.postman.i2p
• --irckeys= - optional keys file for tunnel's local destination
• --eepkeys= - File name containing destination keys, for example privKeys.dat. The file will be created if it does not already exist (issue #110).
• --eephost= - Address incoming trafic forward to. 127.0.0.1 by default
• --eepport= - Port incoming trafic forward to. 80 by default
• --samport= - Port of SAM bridge. Usually 7656. SAM is off if not specified
• --bobport= - Port of BOB command channel. Usually 2827. BOB is off if not specified
• --i2pcontrolport= - Port of I2P control service. Usually 7650. I2PControl is off if not specified
• --conf= - Config file (default: ~/.i2pd/i2p.conf or /var/lib/i2pd/i2p.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.

INI-like, syntax is the following : = . All command-line parameters are allowed as keys, for example:

i2p.conf:

log = 1
v6 = 0
ircdest = irc.postman.i2p

tunnels.cfg (filename of this config is subject of change):

; outgoing tunnel sample, to remote service
; mandatory parameters:
; * type -- always "client"
; * port -- local port to listen to
; * destination -- i2p hostname
; optional parameters (may be omitted)
; * keys -- our identity, if unset, will be generated on every startup,
; if set and file missing, keys will be generated and placed to this file
[IRC]
type = client
port = 6668
destination = irc.echelon.i2p
keys = irc-keys.dat

; incoming tunnel sample, for local service
; mandatory parameters:
; * type -- always "server"
; * host -- ip address of our service
; * port -- port of our service
; * keys -- file with LeaseSet of address in i2p
; optional parameters (may be omitted)
; * inport -- optional, i2p service port, if unset - the same as 'port'
; * accesslist -- comma-separated list of i2p addresses, allowed to connect
; every address is b32 without '.b32.i2p' part
[LOCALSITE]
type = server
host = 127.0.0.1
