I want to setup a small NTP server with ubuntu for a local network. I want that time is taken only from this server and not from outsdie network servers.Also, I want to enable to send MONLIST to clients that request it. I modified the NTP.conf file but I don't think is working. Can you help me? The server has IP address 192.168.2.2 and the client that requires time and MONLIST has IP address 192.168.3.3 The 2 network are connected using a firewall Here is the ntp.conf file
# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help
driftfile /var/lib/ntp/ntp.drift
# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/
