yppasswdd(8)yppasswdd(8)NAME
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 authen‐
tication database. These updates, in combination with password changes
and system administration functions affecting user accounts, are coor‐
dinated 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
