TCPStack

open class TCPStack: TSIPStackDelegate, IPStackProtocol

This class wraps around tun2socks to build a TCP only IP stack.

  • The TCPStack singleton instance.

    Declaration

    Swift

    open static var stack: TCPStack

  • The proxy server that handles connections accepted from this stack.

    Warning

    This must be set before TCPStack is registered to TUNInterface.

    Declaration

    Swift

    open weak var proxyServer: ProxyServer?

  • This is set automatically when the stack is registered to some interface.

    Declaration

    Swift

    open var outputFunc: (([Data], [NSNumber]) -> Void)!

  • Input a packet into the stack.

    Note

    Only process IPv4 TCP packet as of now, since stable lwip does not support ipv6 yet.

    Declaration

    Swift

    open func input(packet: Data, version: NSNumber?) -> Bool

    Parameters

    packet

    The IP packet.
    version

    The version of the IP packet, i.e., AF_INET, AF_INET6.

    Return Value

    If the stack takes in this packet. If the packet is taken in, then it won’t be processed by other IP stacks.

  • Undocumented

    Declaration

    Swift

    open class TCPStack: TSIPStackDelegate, IPStackProtocol

  • Stop the TCP stack.

    After calling this, this stack should never be referenced. Use TCPStack.stack to get a new reference of the singleton.

    Declaration

    Swift

    open func stop()
