Exact time in the FI network

A server can be used to synchronize the exact time of computers . The server provides the exact time log NTP (or SNTP ) from anywhere on the Internet and protocol time (RFC 868) within the FI network.

This server is part of a distributed network of NTP servers NTP Pool Project , see also monitoring graphs for IPv4 and for IPv6 .

You can also read something about our practical experience with NTP operation in the article Accurate time and network transparency our blog.

Unix time synchronization

For accurate synchronization, you need to install the NTP daemon (typically the ntp , No openntpd ). In the configuration file /etc/ntp.conf then we recommend setting up a faculty NTP server, ie adding a line server iburst and comment on lines with directives pool .

The alternative is chrony ( chronyd ). If you are a server have not already been set during installation, this can be done by commenting out the line with the directive pool in the file /etc/chrony.conf and adding a line server iburst .

Time synchronization on Windows

In Windows, the command can be used

w32tm /config / /syncfromflags:manual /update

which must be run on the command line with administrator rights.

To check the settings, use

w32tm /query /configuration
