NAMEyppasswdd — daemon for modifying Network Information Service passwd database DESCRIPTIONThe yppasswdd daemon handles password change requests from yppasswd (see yppasswd(1)). It changes a password entry in passwd_file, which must be in the format defined by passwd(4). The change is made only if the old password provided by yppasswd matches the encrypted password of that entry. yppasswdd should be executed only on the master Network Information Service (NIS) server for the passwd database (map). The yppasswdd daemon is not executed by default, nor can it be started by inetd (see inetd(1M)). To enable automatic startup of yppasswdd at boot time, the NIS_MASTER_SERVER variable should be set to 1 in file /etc/rc.config.d/namesvrs on the master NIS server. Optionsyppasswdd recognizes the following options and command-line arguments:
EXAMPLESAssume the yppasswdd daemon is started on the master NIS server as follows: /usr/lib/netsvc/yp/rpc.yppasswdd /var/yp/src/passwd \ -l /var/adm/yppasswdd.log \ -m passwd DIR=/var/yp/src This indicates that the ASCII file from which the NIS passwd database is built is /var/yp/src/passwd. When this file is updated by a request from yppasswd, the NIS passwd database is rebuilt and copied to all slave NIS servers in the master's NIS domain (see domainname(1)). Log messages are written to the file /var/adm/yppasswdd.log. WARNINGSyppasswdd uses lock file /var/adm/ptmp to get exclusive access to passwd_file when updating it. The file /var/adm/ptmp may persist if passwd_file is being updated and File /var/adm/ptmp must be removed before yppasswdd can function properly again. vipw also uses /var/adm/ptmp when updating /etc/passwd (see vipw(1M)). As a result, yppasswdd competes with vipw when it updates passwd_file if passwd_file is /etc/passwd.
