A server technician needs to access a remote Unix server for administration. The technician has requested that ports 23, 25, and 161 be opened on the router. After the ports are opened, the technician is still unable to connect to the Unix server. Which of the following ports should be opened on the server to allow for remote administration?
A. TCP 21
B. TCP 22
C. UDP 69
D. TCP 3389
There is another question like this on here that says the answer is D. However, B is indeed the correct answer and this question has the right answer. TCP 22 is for Secure Shell (SSH). UNIX utilizes SSH for remote connection. TCP 3380 is for Windows.
Typo** = TCP 3389 is for Windows Remote Desktop Protocol
