| Command | Description |
|---|---|
| ypserv(1Mnis) | Looks up requested information in a map. ypserv is a daemon that runs on NIS servers with a complete set of maps. At least one ypserv daemon must be present on the network for NIS to function. |
| ypbind | Initiates binding. ypbind is the NIS binder daemon. It must be present on both clients and servers. It initiates binding by finding a ypserv process that serves maps within the domain of the requesting client. ypserv must run on each NIS server. For additional information about ypbind, see the ypserv(1Mnis) manual page. |
| ypinit(1Mnis) | Automatically creates maps for an NIS server from files located in /etc. ypinit also constructs the initial maps that are not built from files in /etc, such as ypservers. Use ypinit to set up the master NIS server and the slave NIS servers for the first time, as well as to initialize all clients. |
| ypbuild(1Mnis) | Updates NIS maps by reading /var/yp/Makefile. You can use ypbuild to update all maps based on the input files or to update individual maps. |
| makedbm(1Mnis) | Takes an input file and converts it into valid dbm .dir and .pag files that NIS can use as maps. You can also use makedbm -u to ``disassemble'' a map, so that you can see the key-value pairs that comprise it. |
| ypxfr(1Mnis) | Moves an NIS map from one server to another. You can run ypxfr interactively, or periodically from a crontab file. It is also called by ypserv to initiate a transfer. |
| yppush(1Mnis) | Copies a new version of an NIS map from the NIS master server to its slaves. You run it on the master NIS server. |
| ypset(1Mnis) | Tells a ypbind process to bind to a named NIS server. ypset is not for casual use. |
| yppoll(1Mnis) | Tells which version of an NIS map is running on a server that you specify. It also lists the master server for the map. |
| ypcat(1nis) | Displays the contents of an NIS map. |
| ypmatch(1nis) | Prints the value for one or more specified keys in an NIS map. You cannot specify which NIS server's version of the map you are seeing. |
| ypwhich(1nis) | Shows which NIS server a client is using at the moment for NIS services or, if invoked with the -m mapname option, which NIS server is master of each of the maps. |
| ypupdated(1Mnis) | Facilitates the updating of NIS information. |
| yppasswd(1nis) | Changes user network passwords in the NIS database. |
| yppasswdd(1Mnis) | Handles requests to change user network passwords in the NIS database made by yppasswd (or passwd(1)). |
