About:
Hesiod is a C library that implements the Hesiod name service, which uses DNS TXT records to resolve simple queries for user and group information. It provides a simple, stateless mechanism for distributing configuration data across a network without requiring custom protocols or databases. This allows administrators to manage user accounts and service configurations centrally using existing DNS infrastructure.
Key Features:
  • DNS-based lookup service using TXT records
  • Simple C library API for integration
  • Stateless and scalable architecture
  • Configuration via standard /etc/hesiod.conf file
Use Cases:
  • Centralized user account management in distributed environments
  • Sharing configuration data across multiple servers
  • Lightweight alternative to LDAP for simple lookups
Alternatives:
  • LDAP – More complex and feature-rich, requires dedicated server and schema design
  • NIS – Legacy RPC-based system, less secure and harder to manage than DNS-based solutions
