Hi All, My production platform is a closed system (without internet). I have configured a NTP server (on rhel5.5) which is started and running without error. The problem is that all windows client machines are able to sychronise with my NTP server but RHEL client machines are not able to synch the time. my client config are; */etc/ntp.conf* ** *server 192.168.6.9 restrict default ignore restrict 127.0.0.1 restrict 192.168.6.9 mask 255.255.255.255 nomodify notrap noquery driftfile /var/lib/ntp/drift * i have entry of my NTP server name in step-tickers as well. when I start the service on client I get; [root@TESTAPP ~]# service ntpd restart Shutting down ntpd: [ OK ] ntpd: Synchronizing with time server: [FAILED] Starting ntpd: [ OK ] [root@TESTAPP ~]# ntpdate -q 192.168.6.9 server 192.168.6.9, stratum 10, offset -0.001541, delay 0.02571 10 Feb 08:12:25 ntpdate[8822]: no server suitable for synchronization found [root@TESTAPP ~]# ----- NTP server config is; *server 127.127.1.0* *restrict default kod nomodify notrap noquery nopeer restrict 127.127.1.0 mask 255.255.255.0 nomodify notrap noquery restrict 192.168.11.0 mask 255.255.255.0 nomodify notrap restrict 127.0.0.1* *fudge 127.127.1.0 stratum 10 driftfile /var/lib/ntp/drift broadcastdelay 0.008 keys /etc/ntp/keys logfile /var/log/ntp tos orphan 10 * As mentioned above, with this server configuration windows clients are successfully synchronizing time with ntp server. but rhel servers are not. any help??
