Solaris
"central ntp server", ie, main machine that sync to outside time server
of (startus 1 or 2), and in turn act like main time server for local office.
At TiLeg, this was blazer, 10.215.20.8
cp /etc/inet/ntp.server /etc/inet/ntp.conf
change:
server 204.87.183.6 prefer
fudge 204.87.183.6 1 stratum 4
broadcast 10.215.20.255 ttl 4 # port 123
# 204.87.183.6 is reloj.kjsl.com in Salinas, CA, USA.
# there are other public clock server.
Then, on each subnete, wants to have a broadcast server that send out
NTP info, so any clients on that network can listen to it and sync its clock.
server 10.215.20.8 prefer # blazer, which is "master NTP server"
broadcast 10.215.11.255 ttl 4 # port 123
Solaris client config
On each client, setup to listen to NTP.
cp /etc/inet/ntp.client /etc/inet/ntp.conf
Really just need one line in it, indicating it listen to broadcast NTP packets:
broadcastclient
Alternatively, it can listen to a specific server via:
server 10.215.20.8 prefer
Linux, as client
cp -pa /etc/rc3.d/K74ntpd /etc/rc3.d/S74ntpd
cp -pa /etc/rc5.d/K74ntpd /etc/rc5.d/S74ntpd
/etc/rc3.d/S74ntpd start
There is already a file /etc/ntp.conf with lot of comments, need to update it
as:
A simple client config that listen to broadcast clock:
/etc/ntp.conf ::
broadcastclient
A client that listen to specific server:
server cookoo.unixville.com
server ticktick.unixville.com
A more involved linux config (details TBA):
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
server cookoo.unixville.com
driftfile /var/lib/ntp/drift
broadcastdelay 0.008
authenticate yes
keys /etc/ntp/keys # need to actually setup own key
AIX
AIX, as client that listen to broadcast clock:
/etc/ntp.conf ::
broadcastclient
driftfile /etc/ntp.drift
tracefile /etc/ntp.trace
startsrc -s xntpd
init script to uncomment /etc/rc.tcpip
HPUX
/etc/ntp.conf
broadcastclient
driftfile /var/ntp/ntp.drift
statsdir /var/ntp/ntpstats
/etc/rc.config.d/netdaemon, change:
export NTPDATE_SERVER=10.215.22.5 #bigsur
export XNTPD=1 # def=0, so it won't start
export XNTPD_ARGS=
/sbin/rc2.d/S660xntpd start
NTP-like for windows
An article covering time sync optioins for windows:
http://geodsoft.com/howto/timesync/wininstall.htm
Precompiled SNTP client for windows NT system, refered from above.
http://sourceforge.net/projects/nettime/
Install it as adminstrator, say yes to setup as service.
Do configuration, use 10.215.20.8 (blazer) as server.
It request for 5 machines, but right now we don't have that many NTP server.
Could use the server in the various vlan, which really sync to blazer.
