gen_named

gen_named.sh

Description

This script generates a minimal named.conf configuration file for BIND by scanning a directory of DNS zone files.
For each zone file, it extracts the zone name from the SOA record and creates a corresponding zone block.

---

Usage

./gen_named.sh <path_to_zone_files>

• path_to_zone_files: Directory containing DNS zone files.

Example:

./gen_named.sh /etc/bind/zones

---

Features

• Validates input directory.
• Scans all files in the given directory.
• Extracts the zone name from the first SOA record found.
• Generates a named.conf with minimal zone declarations:

  zone "example.com" { type master; file "/etc/bind/zones/example.com.zone"; };
  

• Warns if no SOA record is found in a zone file.

---

Output

• A file named named.conf is created in the current working directory.
• Example contents:

  // Generated named.conf
  zone "example.com" { type master; file "/etc/bind/zones/example.com"; };
  zone "example.org" { type master; file "/etc/bind/zones/example.org"; };
  

---

Requirements

• Bash
• Standard UNIX tools: grep, awk

---

Notes

• The script assumes each zone file contains a valid SOA record.
• If no SOA record is found, the file is skipped with a warning.
• Useful for quickly bootstrapping a named.conf from existing zone files.
