# Pentesting FTP (port 21)
## When to Use
- Default port `21/tcp` (control), data on `20` (active) or negotiated high ports (passive); FileZilla admin on `14147`; FTPS may use `990`.
- When `nmap`/banner shows `ftp`, `vsFTPd`, `ProFTPD`, `Pure-FTPd`, `FileZilla Server`, or a `220` greeting.
- FTP is **plain-text** and uses `0x0d 0x0a` (CRLF) line endings, so `telnet`/`nc -C` work for manual interaction and the protocol can be abused for relay attacks.
## Quick Enumeration
```bash
# Banner grab (plaintext)
nc -vn <IP> 21
telnet -n <IP> 21
# Grab TLS certificate if FTPS/AUTH TLS is offered
