🌐 FTP Downloads — Old-School but Still Useful!

FTP (File Transfer Protocol) runs on TCP ports 21 & 20 and is another handy method for moving files around a network. 🎯

You can use:

• 📦 The built-in Windows FTP client

• 💻 PowerShell’s Net.WebClient class

---

🐍 Step 1: Set Up Your Own FTP Server (Pwnbox Side)

Use Python3 and the module pyftpdlib to quickly spin up an FTP server:

sudo pip3 install pyftpdlib

Then launch the server on port 21 (default is 2121):

sudo python3 -m pyftpdlib --port 21

✅ This will allow anonymous logins by default (no username or password required).

🪄 Step 2: Download Files Using PowerShell

Here’s a simple one-liner to pull a file from your FTP server:

(New-Object Net.WebClient).DownloadFile('ftp://192.168.49.128/file.txt', 'C:\Users\Public\ftp-file.txt')

📁 This saves file.txt from the FTP server into the Public directory.

🧰 Bonus: Using FTP with a Script (Non-Interactive Shell)

If you're working with a limited shell (interactive shell), here's how to automate FTP with a command file:

echo open 192.168.49.128 > ftpcommand.txt
echo USER anonymous >> ftpcommand.txt
echo binary >> ftpcommand.txt
echo GET file.txt >> ftpcommand.txt
echo bye >> ftpcommand.txt
ftp -v -n -s:ftpcommand.txt

💡 This runs all the FTP steps automatically.

Example output:

ftp> open 192.168.49.128
ftp> USER anonymous
ftp> GET file.txt
ftp> bye

Then check your file with:

more file.txt

📄 Output:

This is a test file

🚨 Quick Tips

• 🛡️ FTP is unencrypted! Avoid using it on sensitive or public networks.

• 🔒 If needed, add authentication to your server.

• 💾 binary mode ensures file integrity when transferring non-text files.
