HOWTO setup a small server
NTP (Network Time Protocol Server)
Installation
To install the NTP server, issue the following command:
# apt-get install ntp
Configuration
If you want to use other servers than Debian's default servers as a
reference, you will have to comment the lines begining with server
in /etc/ntp.conf
and add your own servers, e.g.:
Excerpt: /etc/ntp.conf
server ntps1-1.cs.tu-berlin.de server ntp2.fau.de
Networking Requirements
Prerequisite: Shorewall If you want to allow
other hosts to use your server as time server, you will
have to allow connections to UDP port 123. Add the following lines to
/etc/shorewall/rules
:
Excerpt: /etc/shorewall/rules
# NTP # ACCEPT net $FW udp 123 #
and restart the packet filter:
# shorewall restart
