Goal
Submit the current level password to localhost port 30000.
Why this matters
A simple TCP exchange makes client/server input, output, and service ports tangible.
Progressive hints
Hint 1
Read the current credential from the game-owned password file only inside the session.
Hint 2
Connect to localhost on the named port.
Hint 3
Send one line and wait for the response.
Method
Run only the lines that match the evidence you observe.
nc localhost 30000
# Paste the current game password only into the nc session, then press Enter.Expected non-secret observation
The service acknowledges valid input and returns the next credential in the terminal.
Explanation
netcat opens a raw TCP connection; the remote service interprets the newline-delimited input.
Troubleshooting
- Confirm the port is 30000 and the host is localhost.
- Avoid adding spaces around the credential.
Safety and cleanup
- Use only the OverTheWire game host and your own local practice directory.
- Do not paste a level password into this site, screenshots, notes, or submissions. Baitaphish never asks for credentials.
- Treat commands as learning prompts: inspect paths and flags before running them.
Completion and next step
Use the recovered credential only in the official Level 15 login. Then mark this transition complete and continue.
