                    multiple times, with each occurrence indicat-

     -e             Specify the time (in  seconds)  it  takes  to
                    compute the NTP encryption field on this com-
                    puter

     -f driftfile   Specify the location of the drift file

     -k             Specify the location of the file  which  con- tains the NTP authentication keys     -l logfile  Specify a log file instead of logging to sys- log

     -m             Listen for multicast messages and synchronize  to them if available (requires multicast ker- nel)

     -p  ---->      Specify the name of the file  to  record  the  daemon's process id

     -r             Ordinarily, the daemon automatically  compen-   sates  for  the  network  delay  between  the broadcast/multicast server and the client; if  the  calibration  procedure  fails,  use  the specified default delay (in seconds)

3. Setting up an NTP client

1. Copy over /etc/inet/ntp.client to /etc/inet/ntp.conf :

# cp /etc/inet/ntp.client /etc/inet/ntp.conf

The default ntp.client file uses multicast to receive NTP updates. This can be changed to broadcast as well if you wish to limit where the NTP client can get its updates. (Broadcast packets are not forwarded to other subnets whereas multicast packets are).

#
# /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
