LPIC-2 Exam 201 (Linux Engineer) — Question 55

Which of the following configuration files are used by tcpwrapper?

Answer options

• A. /etc/tcpd.allow and etc/tcpd.deny
• B. /etc/tcpwrapper.allow and /etc/tcpwrapper.deny
• C. /etc/hosts.allow and /etc/hosts.deny
• D. /etc/access.allow and /etc/access.deny
• E. /etc/service.allow and /etc/service.deny

Correct answer: C

Explanation

The correct answer is C, as tcpwrapper uses /etc/hosts.allow and /etc/hosts.deny to control access to services. The other options refer to incorrect or nonexistent configuration files associated with tcpwrapper. A and B mention 'tcpd' and 'tcpwrapper' which are not the actual files used, while D and E reference unrelated files.
