Hi, I am doing this configuration but the last command (which is shown in below) is not running. Please give me the complete solution of NTP server configuration. ** [root@bigboy tmp]# Yum install ntp* -y [root@bigboy tmp]# Vim /etc/ntp.conf Server server.example.com restrict server.example.com mask 255.255.255.255 nomodify notrap noquery restrict 172.24.0.0 mask 255.255.0.0 nomodify notrap restrict 127.0.0.1 [root@bigboy tmp]# chkconfig ntpd on [root@bigboy tmp]# service ntpd start [root@bigboy tmp]# service ntpd stop [root@bigboy tmp]# service ntpd restart [root@bigboy tmp]# pgrep ntpd [root@bigboy tmp]# date [root@bigboy tmp]# service ntpd stop [root@bigboy tmp]# ntpdate –u 172.24.254.254 {this command not running and error message "à no server suitable for synchronization found"} Thanks -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
