yppasswdd, rpc.yppasswdd - server daemon for modifying the Network Information Service (NIS) password file
/usr/sbin/rpc.yppasswdd file [ -m arg1 arg2 ... ]
The yppasswdd daemon is a server that handles password change requests from yppasswd(1). It changes a password entry in the specified file, which is assumed to be in the same format described in passwd(4). An entry in file will be changed only if the password presented by yppasswd(1) matches the encrypted password of that entry.
If the -m option is given, then after file is modified, a make(1) will be performed in /var/yp. Any arguments following the flag will be passed to make. The -m option should be set only at a NIS master server machine.
This server is not run by default, nor can it be started up from inetd(8). If it is desired to enable remote password updating for the NIS, then an entry for yppasswdd should be put in the /sbin/init.d/nis file of the host serving as the master for the NIS passwd file.
If the NIS password file is stored as /var/yp/src/passwd, then to have password changes propagated immediately, the server should be invoked as: /usr/sbin/rpc.yppasswdd /var/yp/src/passwd -m passwd DIR= /var/yp/src
