    Network Time Protokoll

    download für wind00zen: http://www.meinberg.de/german/sw/ntp.htm


    on Debian:

    apt-get install ntpdate (client) and/or ntp (server)

    some public servers for .de

    server ptbtime1.ptb.de
    server ptbtime2.ptb.de
    server ptbtime3.ptb.de
    

    Starting NTPD[edit]

    In Solaris 9 (and probbly a lot of other 8nix servers) you can just...

    /etc/init.d/xntpd start
    

    If you want ntp to start on boot just link the above to rc3 ie

    ln -s /etc/init.d/xntpd /etc/rc3.d/S99ntp
    

    In Solaris 10 NTPD is a service (alavible but disabled by default) so start it with

    svcadm enable network/ntp
    

    or restart it after making chnage to the config like:

    svcadm resnetwork/ntp

    ntp.conf[edit]

    A basic ntp conf (this is one i use on solaris boxes works with Sol 9 and 10) the ntp servers below are just a few that are publicly avalible.

    # ident "@(#)ntp.client 1.3     00/07/17 SMI"
    #
    # /etc/inet/ntp.client
    #
    # An example file that could be copied over to /etc/inet/ntp.conf; it
    # provides a configuration for a host that passively waits for a server
    # to provide NTP packets on the ntp multicast net.
    #
    
    #multicastclient 224.0.1.1
    server chronos.csr.net
    server 81.168.77.149
    server ntp2d.mcc.ac.uk
