Let say my local system's shell prompt is in this format: myname@mysurname:~$

Is it logged in some server when I login there via SSH/FTP? Or is it completely private information?

  • Is this about the shell prompt you see after connecting to a server using SSH? Or is it about the shell prompt on your own local machine, before you've initiated a connection? – Soron Jul 27 '15 at 08:23
  • @EthanKaminski my own local machine before the connection – Onsur Jul 27 '15 at 08:30

No, not by default. When setting up a connection no local username will be send over to the server, only the username / password needed to connect to that server.

They can try to find this out by using something like finger once you have connected, but since you would have to have fingerd running, this is unlikely to happen.

If it is needed to send over the local username, you could send this over as a variable, but this would also need to be configured on the server.

If it's SSH, then normally your connection is encrypted end-to-end. With FTP it would depend on if it's plain ftp (unencryped), SFTP (FTP using SSH, which is encryped) or FTPS (FTP using SSL/TLS, which is also encrypted).

In case of plain FTP, it would definitely leak your username, password and any other information like files present on your machine.
