Rate limitΒΆ

You may want to limit number of tries per user/IP in a short time (especially with sms option). If you enable this, defaults are 2 tries per login and per minute, and same for IP address:

$use_ratelimit = true;

Other possible options for rate limiting:

$ratelimit_dbdir = '/tmp';
$max_attempts_per_user = 2;
$max_attempts_per_ip = 2;
$max_attempts_block_seconds = "60";
$client_ip_header = 'REMOTE_ADDR';

You may want to control rate_limit by IP. To do so you have to specify full local path of file containing json of IP and expected behavior. By default $ratelimit_filter_by_ip_jsonfile is empty, no exclusion is applied.

$ratelimit_filter_by_ip_jsonfile = '/var/www/conf/rrl_filter_by_ip.json';

Example of rrl_filter_by_ip.json file :


Values are integers, excepting for infinite word where check for rate will be disabled.

If no value is given then default will be used:

  • max_per_ip missing uses $max_attempts_per_ip

  • max_per_user missing uses $max_attempts_per_user

  • per_time missing uses $max_attempts_block_seconds

When per_time is set to infinite no check will be done when related IP is used.
