NPT Server - NTP Client no sync hi guys since I got a secure area my linux servers don't not have internet connection at all... so I've configured an NTP Linux server with this configuration but my NTP Linux Client are not sync the time with the NTP Server Network: 192.168.3.0 1. I sync my NTP server to itselft Code: # ntpdate -du ntpserver #service ntpd start 2. I syn my linux clients Code: # ntpdate -du ntpserver ntp service for clients is stop now my NTP server configuration -------------------------------------------- Code: # Permit time synchronization with our time source, but do not # permit the source to query or modify the service on this system. restrict default kod nomodify notrap nopeer noquery restrict -6 default kod nomodify notrap nopeer noquery # Permit all access over the loopback interface.
