Build Statuses

• 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

Building from source

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

Note that cmake will automatically create a directory for storing configuration files. To change the location of this directory, you must set the I2PD_DATA_DIR flag. This does not apply to core-only builds.

Building Unit Tests

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

Cmdline options

• --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)
• --httpproxyaddress= - The address to listen on (HTTP Proxy)
• --socksproxyport= - The port to listen on (SOCKS Proxy)
• --socksproxyaddress= - The address 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
• --ircaddress= - The adddress of IRC tunnel to listen on, 127.0.0.1 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).
• --eepaddress= - 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

• --bobaddress= - Address of BOB service, 127.0.0.1 by default (only used if BOB is on)
• --i2pcontrolport= - Port of I2P control service. Usually 7650. I2PControl is off if not specified
• --i2pcontroladdress= - Address of I2P control service, 127.0.0.1 by default (only used if I2PControl is on)
• --i2pcontrolpassword= - I2P control service password, "itoopie" by default
• --tunnelscfg= - Tunnels Config file (default: ~/.i2pd/tunnels.cfg or /var/lib/i2pd/tunnels.cfg)
• --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.

Config files

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]
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   
port = 80   
keys = site-keys.dat   
inport = 81   
accesslist = <b32>[,<b32>]
