7 Setting up a NYS Server

The NIS/NYS server software can be found on:

    Site                Directory                          File Name

    ftp.lysator.liu.se  /pub/NYS                           ypserv-0.11.tar.gz
    ftp.univie.ac.at    /unix/system/linux/funet/BETA/NYS  ypserv-0.11.tar.gz
    mcsun.eu.net        /os/linux/BETA/NYS                 ypserv-0.11.tar.gz

The server setup is the same for both NIS and NYS.

Compile the software to generate the 'ypserv', 'dbcat' and 'dbload' programs. Firstly, determine what files you require to be available via NIS/NYS and then add or remove the appropriate entries to the ypMakefile. Now build the DBM files by

    % make -f ypMakefile

Make sure the portmapper (rpc.portmap) is running, and start the server 'ypserv'. The command

    % rpcinfo -u localhost ypserv

should output something like

    program 100004 version 2 ready and waiting

That's it, your server is up and running.

Whenever users change their passwords, the NIS password database and probably other NIS databases, which depend on the NIS password database, should be updated. The program "yppasswdd" is a server that handles password changes and makes sure that the NIS information will be updated accordingly. The software for "yppasswdd" can be found on:

    Site                   Directory        File Name

    ftp.lysator.liu.se    /pub/NYS          yppasswdd-0.1.tar.gz

Once you obtained the software, please follow the instructions which come with the software.
