BannedConnectionError bans a connection.

Types ¶

type BanIPv4 ¶

type BanIPv4 struct{}

BanIPv4 ban IPv4 addresses

func (BanIPv4) Blocked ¶

func (BanIPv4) Blocked(ip net.IP, port int) error

Blocked prevents connections from IPv4 addresses.

type BanIPv6 ¶

func (BanIPv6) Blocked ¶

func (BanIPv6) Blocked(ip net.IP, p int) error

Blocked prevents connections from IPv6 addresses.

type BanInvalidPort ¶

type BanInvalidPort struct{}

BanInvalidPort blocks connections with invalid port values.

func (BanInvalidPort) Blocked ¶

func (BanInvalidPort) Blocked(ip net.IP, port int) error

Blocked prevents connections from ipv4 addresses.

type BloomBanIP ¶

type BloomBanIP struct {
	// contains filtered or unexported fields
}

BloomBanIP bans an IP address by adding it to a bloom filter. BloomBanIP is stateful, and will track banned connections using a bloom filter.

func NewBloomBanIP ¶

func NewBloomBanIP(d time.Duration) *BloomBanIP

NewBloomBanIP bans an IP address by adding to a bloom filter.

func (*BloomBanIP) Blocked ¶

func (t *BloomBanIP) Blocked(ip net.IP, p int) error

Blocked prevents connections from IPv6 addresses.

func (*BloomBanIP) Inhibit ¶

func (t *BloomBanIP) Inhibit(ip net.IP, port int, cause error)

Inhibit ban an IP address within the smallest 8 bit range.

type Firewall ¶

type Firewall interface {
	Blocked(ip net.IP, port int) error
}

Firewall used to prevent connections.

type FirewallStateful ¶

type FirewallStateful interface {
	Firewall
	Inhibit(ip net.IP, port int, cause error)
}

FirewallStateful used when the firewall needs to be updated dynamically.

func AutoFirewall ¶

func AutoFirewall() FirewallStateful

AutoFirewall reasonable default firewall settings.

func NewFirewall ¶

func NewFirewall(rules ...Firewall) FirewallStateful

NewFirewall compose multiple firewalls into a single firewall.

type Handshaker ¶

type Handshaker interface {
	Accept(l net.Listener) (net.Conn, error)
	Release(c net.Conn, cause error) error
}
