nsswitch.conf and NIS domain

[contigab]

Hi, I have a NIS domain for my domestic lan and everything is configured correctly but i just would like to know if someone could explain me a little bit better how nsswitch.conf works in order to control some more features of NIS. I would like to centralize groups and hosts configuration files so that i can configure them once.

nsswitch specifies in which order the OS accesses the file

using hosts as an example:

hosts: nis files

when the OS queries the hosts file, it will go to NIS first, then /etc/hosts

make sense?
