Set Key Type to Use for Authenticated Requests (DES|MD5)
NTP supports two types of encryption: DES or MD5. If you decide to use encryption to
authenticate NTP information and configuration requests, you must specify which type of
encryption to use.
To specify an encryption type enter the
ntpkeytype command as shown:
ntpkeytype <value>
where <value> is either DES or MD5. For example, to set the key type to MD5, you would
enter:
ntpkeytype MD5
To view the currently specified key type, enter the ntpkeytype command at the system
prompt, and press <return>. A message similar to the following is displayed:
keytype is MD5
Set a System Flag (Auth, Bclient, Monitor, Stats)
The ntpenable command provides a way to enable various server options by creating flags
added to NTP messages sent to the server.
To set a system flag, enter the
ntpenable command as shown:
ntpenable <flag>
where <flag> is the type of flag the server will receive. There are six flag types that can be set:
auth This flag causes the server to synchronize with unconfigured
peers only if the peer has been correctly authenticated using a
trusted key and key identifier. The default for this flag is
disabled (off).
bclient This flag causes the server to listen for a message from a broad-
cast or multicast server, following which an association is auto-
matically instantiated for that server. The default for this flag is
disabled (off).
monitor This flag enables the monitoring facility. The default for this flag
is disabled (off).
stats This flag enables the statistics facility file generator. The default
for this flag is enable (on).
When you have finished specifying a flag, press
<enter>. A brief message appears to confirm
the operation.
Clear a System Flag (Auth, Bclient, Monitor, Stats)
The ntpdisable command allows you to remove previously set flags from NTP messages sent to
the server.
To disable a flag, enter the
ntpdisable command as follows:
ntpdisable <flag>
where <flag> is the type of flag the server will receive. There are six flag types that can be set
and removed. The flags are described in the section Set a System Flag (Auth, Bclient, Monitor,
Stats) on page 12-35.
