Network Time Protokoll
download für wind00zen: http://www.meinberg.de/german/sw/ntp.htm
on Debian:
apt-get install ntpdate
Starting NTPD
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
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
