Nostale Packet Logger

Best for: Learning and education. How it works: Use scapy to sniff TCP port 4000-4010 (typical Nostale ports) and a custom decryption routine from GitHub Gists. Pros: Total control; cross-platform. Cons: High latency; not real-time friendly.

Example raw packet (hex):

AA 00 04 01 00 00 00 0B 00 00

Interpretation might be: length 0x00AA, opcode 0x0401, followed by parameters. nostale packet logger

Modern Nostale clients (especially official Gameforge versions) use encryption to prevent simple sniffing. Best for: Learning and education

There is no official "Nostale Packet Logger" from Gameforge. The tools are community-made. Here are the most prominent ones as of 2025. Example raw packet (hex): AA 00 04 01 00 00 00 0B 00 00

This is a double-edged sword. Security researchers use loggers to find "packet injection" vulnerabilities. For instance, if a client sends the price of an item in the shop window, and the server doesn't re-validate it, a hacker could modify the outgoing packet to buy a Raid Box for 1 gold. Logging is the first step to discovering such flaws.
