Now I have finally understood why the teacher adds a file in my folder, and fill in the IP address of the other party. It is used to use it when the security check is used. If there is no file If the SCP will report a Warning:
THE
Authenticity of host '10 .60.38.3 (10.60.38.3) 'Can't Be Established.RSA Key Fingerprint IS 41: 5A: 61: A4: 0E: EB: 3A: 3C: DA: 88: 1D: F2: 52: EE : a9: 7f.are you Sure You Want to Continue Connecting (YES / NO)? There will be a WARNING: Warning:
Permanently Added '10.60.38.3 '(RSA) To the list of knower If you add that file does not have these two Warning, what is that the file is, now you can't know it, ask the teacher when you are in class, huh, huh
Specific example:
[S021636 @ Linux01 HOMEWORK] $ SCP
B02142047_ZHANGMINGJIN@10.60.38.3: /Home/b02142047_zhangmingjin/homework/shell.c
This also enters the password after you can Copy the shell.c file on another host
