Disable the IPv6 protocol
Medium Severity
Disable support for IP version 6 (IPv6). The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_IPV6
, run the following command:
grep CONFIG_IPV6 /boot/config-*
Configs with value 'n' are not explicitly set in the file, so either commented lines or no lines should be returned.
