TCP & UDP Packet Sender App-Analysen für 8. September

TCP & UDP Packet Sender is a focused network utility for developers, QA engineers, network admins, and hobbyists. Compose a message, choose a protocol, hit send, and see exactly what comes back — down to the byte. COMPOSE & SEND • Send TCP or UDP packets to any host and port • Enter payloads as UTF-8/ASCII text or raw HEX (flexible hex parsing: spaces, 0x, commas, and \x are all accepted) • Live byte counter and a full hex-dump preview before you send • Send once, repeat a set number of times, or flood — with a configurable delay between sends • Randomize the destination port on each send SECURE CONNECTIONS • TLS over TCP and DTLS over UDP with a single toggle • Responses over secure connections are captured automatically TCP CONNECTION OPTIONS • No-delay (TCP_NODELAY) for lower latency • Keepalive probes • TCP Fast Open • Send FIN (write-close) immediately after the payload RECEIVE MODE (LISTENER) • Run a local TCP or UDP server on a port you choose • Watch incoming connections and data arrive in real time • Live counters for active connections and messages received • Everything received flows straight into the traffic log TRAFFIC LOG & INSPECTOR • Every packet sent and received is logged, newest first • Inspect any capture as a classic hex dump, plain hex, or ASCII • One-tap copy of any representation • Clear the log anytime; history is saved between launches PACKET LIBRARY • Save packets you use often and reload them instantly • Per-packet response history follows each saved packet • Export your whole library to a JSON file and import it on another device BUILT-IN TOOLS • DNS forward lookup (hostname → IPv4/IPv6) • Reverse DNS lookup (IP → hostname) • Live hex ⇄ text converter DESIGNED FOR iOS • Universal app for iPhone and iPad • Clean, modern interface with haptics and full dark-mode support PRIVACY No accounts, no analytics, no tracking, no ads, no third-party SDKs. Your packets, library, and logs never leave your device except when you explicitly export them. Traffic goes directly to the hosts you target — never to us. WHAT THIS APP DOES NOT DO (PLEASE READ) This app operates at the TCP/UDP (transport) layer using Apple's standard networking stack. Because iOS does not grant apps raw-socket access, it cannot: • Craft raw IP or Ethernet frames • Set raw TCP header flags such as SYN, ACK, RST, PSH, or URG (so it cannot perform SYN scans or spoofed segments) • Send ICMP/ping, run a raw traceroute, or do ARP / Neighbor Discovery • Build IPv6 extension headers or 6to4 tunnels If you need TCP/UDP messaging, testing, and inspection — this is your tool. If you need raw packet crafting, that requires a desktop OS with root privileges.
