check_fqdn.sh

This script is designed to validate and, if necessary, correct the system’s configured Fully Qualified Domain Name (FQDN) on Debian/Ubuntu (and similar) systems. It:

1. Checks if the current operating system is a Debian/Ubuntu (APT-based) distribution.
2. Ensures required system commands are installed, attempting silent installation via apt-get if necessary.
3. Identifies the default route’s interface for both IPv4 and IPv6.
4. Retrieves the primary global (i.e., non-local) IPv4 and IPv6 addresses on those interfaces.
5. Performs reverse DNS lookups on those local addresses to determine their FQDNs.
6. Ensures that the forward DNS record for that FQDN matches both IP addresses.
