New in version 2.0.10
• New widget
• Advanced sequence list configuration
Unlock your server's secret knock!
Knock on Ports is the ultimate port knocking client for Android, giving you secure and seamless access to services hidden behind firewalls.
Craft custom knock sequences using UDP, TCP, or ICMP packets (IPv4/IPv6 support) to keep your server ports stealthy until the right "knock" unlocks them.
Why Knock on Ports?
• Flexible Sequences: Customize UDP/TCP/ICMP packets, set interpacket delays, and fine-tune TTL/Hop Limit for all protocols.
• Smart Automation: Trigger apps (e.g., SSH) or URLs after a successful knock. Integrate with external tools via URI for advanced workflows.
• Connect Anywhere: Full IPv4 & IPv6 compatibility.
• Quick Access: Home screen shortcuts and a widget for instant sequence launches.
• Customizable Look: Dynamic themes (Android 12+), custom colors, light/dark modes, and contrast controls.
• Data Control: Export/import configurations effortlessly.
• No Ads, Open Source: Free, transparent, and privacy-focused.
Download now and knock with confidence!
