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.
INI-like, syntax is the following : = .
Comments are "#", not ";" as you may expect. See boost ticket
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 page.
