PortKnock: Secure Your Network with Ease
PortKnock by Danny Sung offers an intuitive and efficient solution for enhancing network security through port knocking, making unauthorized access significantly more challenging.
Overview
- This application is a simple port knocker for the iPhone, primarily useful for network administrators. It requires a port knock daemon to be running on the server for functionality.
Features in this version of Port Knock:
- Password Protection
- Knock Validation
- Import/Export Hosts
- Auto App Launcher(+)
- Knock Progress Screen
- Shows your External IP Address
- Arbitrary number of ports per host
- An unlimited number of host definitions
- TCP/UDP configuration per port
- Selectively sending knocks through WiFi or Carrier/3G networks
- Configurable interpacket delay
- No advertising
Use Cases
- This app is convenient when on a WiFi network without access to a port knocker on available computers. It can also be effectively used with TouchTerm or any other ssh or telnet software by providing the hostname and a list of ports with the choice of sending TCP or UDP packets.
Brief Description of Port Knocking for the Layman:
- Port Knocking is a security technique to protect services behind a firewall until a specific knock sequence is given, distinct from port scanning which is used for discovering open services on a system.
- Imagine leaving your kids at home alone. You teach them to listen for a certain knock that only your family knows, similar to how servers can be instructed to respond to specific knocks sent via this application.
Additional Info
- If you require a knock server, Judd Vinet's knock daemon for Linux is recommended due to its ease of use: http://www.zeroflux.org/projects/knock

Notes
- + Some limitations apply to the Auto App Launcher feature; for SSH, only temporary connections can be created, and Mail operations may initiate a new compose mail window first due to iOS integration constraints.
Support
- To report bugs and suggest features, contact [email protected] for prompt assistance rather than posting in reviews.
History
- 2022-02-28 PortKnock 4.18 released with restored functionality of Auto App Launcher and resolved import bugs.
