Question: 1 / 485

Which port corresponds to the rlogin service?

Port 666

Port 513

The rlogin service, which stands for "remote login," uses port 513 for its operations. This service allows users to log into another host over a network using a network protocol.

Port 513 is specifically designated for rlogin connections as per the Internet Assigned Numbers Authority (IANA) service port assignments. Rlogin enables a user to execute commands on a remote server as if they were using a physical terminal connected directly to that server.

In contrast, the other options relate to different services. Port 666 is commonly associated with the Internet Relay Chat (IRC) protocol, port 8080 is often used as an alternative port for HTTP traffic, and port 22 is the standard port for Secure Shell (SSH), which is a protocol used for secure remote logins. By identifying that port 513 is designated for rlogin, one can see why this is the correct choice.
