i2pd configuration
==================

i2pd can be configured via either command-line arguments or config files. 
Modifying `i2pd.conf` is just a way of passing command line arguments to i2pd at boot; 
for example, running i2pd with argument `--port=10123` and setting option `port = 10123` in config file will have 
the same effect.

There are two separate config files: `i2pd.conf` and `tunnels.conf`. `i2pd.conf` is the main configuration file, where
you configure all options. `tunnels.conf` is the tunnel configuration file, where you configure I2P hidden services
and client tunnels. the `tunnels.conf` options are documented [here](tunnels.md).

`i2pd.conf` accets INI-like syntax, such as the following : <key> = <value>.
Comments are "#", not ";" as you might expect. See [boost ticket](https://svn.boost.org/trac/boost/ticket/808)
All command-line parameters are allowed as keys, but for those which contains dot (.), there is a special syntax.

For example:

i2pd.conf:

    # comment
    log = true
    ipv6 = true
    # settings for specific module
    [httpproxy]
    port = 4444
    # ^^ this will be --httproxy.port= in cmdline
    # another comment
    [sam]
    enabled = true

You are also encouraged to see the commented config with examples of all options in ``contrib/i2pd.conf``.

Options specified on the command line take precedence over those in the config file.
If you are upgrading your very old router (< 2.3.0) see also [this](config_opts_after_2.3.0.md) page.
