i2pd configuration
==================
i2pd can be configured via command-line arguments and config files.
Options are the same, for example, running i2pd with argument `--port=10123` and setting
option `port = 10123` in config file will have same effect.
There are two separate config files `i2pd.conf` and `tunnels.conf` . `i2pd.conf` is main configuration file, where
you configure all options. `tunnels.conf` is I2P tunnel configuration file, where you configure I2P hidden services
and client tunnels for you needs. `tunnels.conf` options are documented [here ](tunnels.md ).
INI-like, syntax is the following : < key > = < value > .
Comments are "#", not ";" as you may expect. See [boost ticket ](https://svn.boost.org/trac/boost/ticket/808 )
All command-line parameters are allowed as keys, but note for those which contains dot (.).
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
See also commented config with examples of all options in ``docs/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 .
