Partly checked. None of the 3 questions here has been read against the cited source by a person. 3 questions have been checked against their cited clause by an automated pass — which is not the same thing, and is not a signature.
Only questions a person has signed for are used in mock exams here. That is the whole difference between the two kinds of checking above.
Questions in this lesson
- On a Linux system using shadow passwords, what appears in the second (password) field of a normal user's line in /etc/passwd, and where does the password hash actually live? machine-checked
- On a host using TCP wrappers, /etc/hosts.deny contains `ALL: ALL` and /etc/hosts.allow contains `sshd: 192.168.1.`. A wrapped connection arrives from 192.168.1.50 for sshd. What happens? machine-checked
- A legacy host runs its telnet service under xinetd, configured in /etc/xinetd.d/telnet. Which change turns the service off while keeping the configuration file in place? machine-checked
