Once you connect to a machine with sftp, you will be presented with the sftp> prompt. At this prompt, you can type a variety of commands, including help, which will display a list of all possible commands. These commands include most of the traditional FTP commands, such as get to download files and put to upload files. The primary commands you will need to use are ls to list files, get to download files, and put to upload files. Retrieve the lsof.txt file, then screenshot the contents of that file as your answer. Type: ls Note down the answer. msfadmin@metasploitable:~$ sftp root@KALI_IP sftp> help sftp> ls sftp> get lsof.txt sftp> quit Type: ls 14) Can you see any difference between the between the result you got from your previously typed ls command and the currently typed ls command? What is the difference and why you have that difference?
