yppasswdd, rpc.yppasswdd - server daemon for modifying the Network Information Service (NIS) password file SYNOPSIS
/usr/sbin/rpc.yppasswdd file [-m arg1 arg2...] DESCRIPTION
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 option 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. SECURITY NOTE
When enhanced security is installed and NIS is used to distribute the protected password authentication database, the yppasswdd daemon man- ages writes to that database. A strict C2 security policy, which is optionally configurable using enhanced security, requires each user login or login failure to be recorded in the protected password authentication database. These updates, in combination with password changes and system administration functions affecting user accounts, are coordinated by the daemon. EXAMPLES
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 FILES

yppasswdd: rpc.yppasswdd - daemon for modifying Network Information Service passwd database SYNOPSIS
passwd_file log_file] [arg1 arg2 ...]] directory] log_file] [arg1 arg2 ...]] Remarks The Network Information Service (NIS) was formerly known as Yellow Pages (yp). Although the name has changed, the functionality of the service remains the same. DESCRIPTION
The daemon handles password change requests from (see yppasswd(1)). It changes a password entry in the passwd and shadow files. The passwd and shadow files provide the basis for the passwd.byname and passwd.byuid maps. Entries in the passwd or shadow files are changed only if the password presented by matches the encrypted password of the entry. All password files are located in the directory. If the option is given, the passwd or shadow files are placed under the directory path that is the argument to should be executed only on the master Network Information Service (NIS) server for the passwd database (map). The daemon is not executed by default, nor can it be started by (see inetd(1M)). To enable automatic startup of at boot time, the variable should be set to 1 in file on the master NIS server. The daemon in HP-UX 11i version 3 supports the shadow mode. The system can be converted to shadow mode by using and reverted by using The variable must be set to 1 in file on the master NIS server to support the shadow mode in NIS. The server does not insist on the presence of a shadow file unless there is no option present or the directory named with the option is Options recognizes the following options and command-line arguments: Log diagnostic and error messages to log_file. These messages are not available if is started without the option. Information logged to the file includes date and time of the message, the host name, process ID and name of the function generating the message, and the message itself. Note that different services can share a single log file because enough information is included to uniquely identify each message. If these are given, then these fields may not be changed remotely using is HP specific. After the password or shadow file is modified, and if using the option, executes to update the NIS passwd database (see ypmake(1M)). Any arguments following the flag are passed to To ensure that the passwd map is rebuilt to contain the new password and all slave NIS servers have their passwd maps properly updated to include the change, always use the option to but do not use the argument to The directory input specifies which directory contains the passwd file (and the shadow file when the system is in shadow mode). Note that the directory specified must contain the file named "passwd". If shadow mode is enabled, then the directory specified must contain a file called "shadow". EXAMPLES
Assume the daemon is started on the master NIS server as follows: This indicates that the ASCII file from which the NIS passwd database is built is When this file is updated by a request from 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 WARNINGS
