NIS Screen

NIS (Network Information Service) is a client–server directory service protocol for distributing system configuration data such as user and host names between computers on a computer network.

A NIS system maintains and distributes a central directory of user and group information, host names, e-mail aliases and other text-based tables of information in a computer network. In FreeBSD, the list of users is placed in /etc/passwd and authentication hashes in /etc/shadow. NIS adds another global user list to identify users on any NIS domain client.
NIS is limited in scalability and security. For modern networks, LDAP has replaced NIS.

To configure NIS, go to Directory Services > NIS.


Enter the NIS Domain name and list any NIS Servers (host names or IP addresses). Press Enter to separate server entries. Configure the remaining options as needed:

  • Secure Mode : Set to have ypbind(8) refuse to bind to any NIS server not running as root on a TCP port over 1024.
  • Manycast : Set for ypbind to bind to the fastest responding server.
  • Enable : Unset to disable the configuration without deleting it.

When ready, SAVE the configuration.
