SNTPD is installed in the /usr/sbin/sntpd directory.
To
start the SNTP server from the z/OS® shell
command line, type sntpd & on the command line.
This starts sntpd and sends it to the background.
The following
optional parameters are used for the sntpd command:
- -d
- Enables debugging. Debug messages go to syslogd daemon.
- -df pathname
- Enables debugging. Debug messages go to specified file location.
- -pf pathname
- Specifies z/OS UNIX path for process ID file.
- -b nnnnn
- Acts in broadcast mode. This parameter sends local broadcasts
on all interfaces every nnnnn seconds. The
valid range for -b is 1 - 16284.
- -m nnnnn
- Acts in multicast mode. Sends multicast updates (TTL=1) on all
interfaces every nnnnn seconds. The valid
range for -m is 1 - 16284.
- -s n
- Use n as the stratum level in all replies
sent by the server. The valid range for n is
1 - 15. If -s is not specified or an invalid value is specified,
the default stratum level of 1 is used. The stratum level indicates
the relative accuracy of the local clock compared to the clocks of
other SNTP servers in the network. The value 1 is the most accurate
and 15 is the least accurate.
Guideline: The SNTP
server always responds to client requests (unicast mode), regardless
if -b or -m start options are specified.
