• 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/build
• $ cmake ..
• $ make

Then, run it:

$ ./i2pd

The client should now reseed by itself.

By default, the web console is located at http://localhost:7070/.

For a list of cmake options, see build/BUILD_NOTES.md

To build unit tests, you'll need to install the boost unit test framework.

On Ubuntu/Debian based

• sudo apt-get install libboost-test-dev

To build the tests, run

$ cmake .. -DWITH_TESTS=ON

• --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
; * address -- address to listen on, 127.0.0.1 by default
[IRC]

port = 6668
destination = irc.echelon.i2p

; 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
