The File Transfer Protocol (FTP) is a common protocol which you may find during a penetration test. It is a TCP-based protocol and runs on port 21. Luckily, its enumeration is simple and rather straight-forward.
You can use the ftp
command if you have credentials:
ftp <ip>
You can then proceed with typical navigation commands like dir
, cd
, pwd
, get
and send
to navigate and interact with the remote file system.
If you don't have credentials you can try with the usernames guest
, anonymous
, or ftp
and an empty password in order to test for anonymous login.
