NAME    [Toc]    [Back]

       yppasswdd, rpc.yppasswdd - server daemon for modifying the
       Network Information Service (NIS) password file

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/rpc.yppasswdd file [-m arg1 arg2...]

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       When enhanced security is installed and  NIS  is  used  to
       distribute the protected password authentication database,
       the yppasswdd daemon manages 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    [Toc]    [Back]

       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
