![]() Also the outbound packet rate will be the same as without RRL. The amplification factor of the attack will be reduced, but the outbound data bandwidth won't be lower than the incoming bandwidth. Setting the value to 1 will cause that all rate-limited responses will be sent as truncated.Therefore this setting is not recommended. All legitimate requestors affected by the limit will face denial of service and will observe excessive timeouts. The outbound bandwidth and packet rate will be strictly capped by the rate-limit option. Setting the value to 0 will cause that all rate-limited responses will be dropped.It is worth noting, that some responses can't be truncated (e.g. The idea behind SLIP mechanism is to send each N th response as truncated, thus allowing client to reconnect via TCP for at least some degree of service. Each settings block begins with a unique identifier, which can be used as a reference from other sections (such identifier must be defined in advance).Ī multi-valued item can be specified either as a YAML sequence:Īs attacks using DNS/UDP are usually based on a forged source address, an attacker could deny services to the victim's netblock if all responses would be completely blocked. Most of the sections (excluding server, control, and statistics) are sequences of settings blocks. There are 11 main sections ( server, control, log, statistics, keystore, policy, key, acl, remote, template, and zone) and module sections with the mod- prefix. – Multi-valued item, order of the values is preserved SIZE – Number of bytes, an integer with possible size multiplier suffix ( B ~ 1, K ~ 1024, M ~ 1024^2 or G ~ 1024^3). ![]()
