The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

# Reconstructed from oval:mil.disa.fso.rhel11:def:417
# The DHCP client must not send dynamic DNS updates.
# Per-module read mechanism curated from static teardown of DISA's SCC tool
# (SCAP Compliance Checker) -- see the SCC Automation Reference above.
#
# MANUAL REVIEW REQUIRED -- the module(s) below could not be reconstructed
# into working code from curated SCC reference data, and are excluded from
# the automated result:
# - textfilecontent54_object (textfilecontent54_test) -- do-foward-updates is false: no extractor for field "subexpression"
# dhclient is not installed
# rpminfo_object (rpminfo_test)
