Updates information in Network Information Services (NIS) maps.
The ypupdated daemon updates information in Network Information Services (NIS) maps. Before it can update information, however, the daemon consults the updaters file in the /var/yp directory to determine which NIS maps should be updated and how they should be changed.
By default, the ypupdated daemon requires the most secure method of authentication available to it, either DES (secure) or UNIX (insecure).
The ypupdated daemon is started and stopped by the following System Resource Controller (SRC) commands:
startsrc -s ypupdated
stopsrc -s ypupdated| Item | Description |
|---|---|
| -s | Accepts only calls authenticated using the secure Remote Procedure Call (RPC) mechanism (AUTH_DES authentication). This disables programmatic updating of NIS maps unless the network supports these calls. |
| -i | Accepts RPC calls with the insecure AUTH_UNIX credentials. This allows programmatic updating of NIS maps in all networks. |
To start the ypupdated daemon from the command line, type:
startsrc -s ypupdated| Item | Description |
|---|---|
| /var/yp/updaters | A makefile for updating NIS maps. |
