******* Inicio : Acerca de este Guiin ********

Yo intento escribir guiones compatibles con
Sistemas operativos Unix & POSIX , y otros
Sistemas operativos que soporten bash

Este archivo es un guion sencillo para
Sincronizar la hora utilizando
i ntpdate i (asi que debe estar instalado)

exit 0right now i prefer use " Network Manager " for manual configuration IP inside the KDE Plasma Desktop [ Grafical Session ].

if i try ran commands like normal user :

Code:su -c "gpasswd -a inukaze ntp ; gpasswd -a inukaze ntpd" rootQuote:

Contraseia: Aiadiendo al usuario inukaze al grupo ntp gpasswd: el grupo intpdi no existe en /etc/group

Code:rcntpd stopQuote:

Stopping NTP daemon.../etc/rc.d/rc.ntpd: linea 15: kill: (1022) - Operaciin no permitida rm: no se puede borrar '/run/ntpd.pid': Permiso denegado

if my user is part of ntp group, why not had permission to delete the file '/run/ntpd.pid' ?

Code:ntpdate -u time.nist.govQuote:

28 Apr 17:51:02 ntpdate[3406]: step-systime: Operation not permitted

Code:$rcntpd startQuote:

Starting NTP daemon: /usr/sbin/ntpd -g -u ntp:ntp28 Apr 17:54:45 ntpd[3943]: must be run as root, not uid 1000

Code:hwclock -wQuote:

bash: hwclock: orden no encontrada

The hwclock command just can be use by the root ?

Ok why for just sync clock hour i need root permission ?

Which things i should edit for all users inside ntp group can use commands ; ntpd, hwclock

stop/start/restart/status ntp, ntpd, services.
can delete and create the file " /run/ntpd.pid "
