Re: ntp daemon.

[Balint Szigeti <balint.szgt@gmail.com>]

Okay, at first we need to  ntp.conf.
Please run cat /etc/ntp.conf and paste here the results.
Check your firewall with 'iptables -L' command and also run this 
'netstat -tulpn|grep ntp'.
Please, paste here every command output.

Regards,
Balint
