Hi could you help me with this problem of  scp connection in Linux? Let me put the question of the exercise below for you: Log in to the remote system (cntserv.hacc.edu) and begin. The password to get into this quiz can be obtained by using scp to copy a file.  Do not use the -R or -r option for scp.  If you do, your day will get worse. The file is located in the remote user's home directory on the remote system in a file named mod3PW The remote system has the IP 192.168.240.102.   You will use the username scp with the password scp_password to scp the file.   Once you have the file locally (on cntserv) you can display the contents using the cat command. THE HINTS MAY OR MAY NOT HAVE THE CORRECT PATH TO THE FILES.  YOU SHOULD MAKE SURE THE COMMAND WORKS, AND NOT JUST COPY/PASTE THE HINT INTO THE ANSWER BOX.       Here is what i have done, could you give  step by step  path to unstuck me, please? What am i doing wrong?
