yppasswdd(1M) yppasswdd(1M)

EXAMPLES

Assume 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

/usr/lib/netsvc/yp/rpc.yppasswdd -D /opt \

-l /var/adm/yppasswdd.log \

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 data-

base 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

WARNINGS

yppasswdd 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

• The system crashes or

•

yppasswdd is killed using SIGKILL (see kill(1) and signal(2)).

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
