ntp_authspeed(1Mtcp)


ntp_authspeed -- compute NTP authentication delay

Synopsis

ntp_authspeed [-c] [-d] [-m] [-nnumber] sample_keys_file

Description

ntp_authspeed is used to calculate values for the authdelay entry in /etc/inet/ntp.conf (see xntpd(1Mtcp)).

When run on a sample keys file (sample_keys_file), ntp_authspeed will output suggested values for authdelay.

Options

-c
Computes and displays the actual cost of the computations, rather than displaying the suggested value for authdelay.

-d
Enables debugging output.

-m
Computes the delay for MD5 authentication. This is the default as DES authentication is not currently supported, but the option remains for backward compatibility.

-n number
Perform number computational loops instead of the default of 20000 (or 2000 if -c is used).
The format of the key entries is described in xntpd(1Mtcp). Only key entries of type ``M'' for MD5 authentication are supported at this time.

Files

/etc/inet/ntp.samplekeys
sample key file
