Overview

Name_service_switch

Manage the name service switch - Manage the name service switch - /etc/nsswitch.conf on Linux and Solaris, /etc/netsvc.conf on AIX

The different supported platforms have different ways of assigning values in their respective configuration files. For example, solaris uses: :\tVALUE Whereas AIX uses: = In the examples above, up-to three characters are used to delimit a key vs a value. Taking AIX, ldelim is , delim is and rdelim is “.

The module largely takes care of these idiosyncrasies itself, however, you may override via parameters if necessary

Parameters:

  • nss_owner (String) (defaults to: $name_service_switch::params::nss_owner) —

    File owner for files managed

  • nss_path (String) (defaults to: $name_service_switch::params::nss_path) —

    Path to file containing name service switch information

  • nss_group (String) (defaults to: $name_service_switch::params::nss_group) —

    File group for files managed

  • nss_mode (String) (defaults to: $name_service_switch::params::nss_mode) —

    File mode for files managed

  • ldelim (String) (defaults to: $name_service_switch::params::ldelim) —

    Left delimiter between a key and a value

  • delim (String) (defaults to: $name_service_switch::params::delim) —

    Central delimiter between a key and a value

  • rdelim (String) (defaults to: $name_service_switch::params::rdelim) —

    Right delimiter between a key and a value

  • entries (Hash[String,String]) (defaults to: $name_service_switch::params::entries) —

    Hash of key value pairs to add to the name service switch file. If entries already exist they will be edited to show the values in this hash. The keyname is the the switch you are changing, eg hosts and the value is the desired new setting, eg files dns
