Field Descriptions
The following section describes the expanded menu options.
61) Client limit
This field allows you to set a specific number of clients that are allowed to make requests of
the server during a specified time period. Setting this field to
0 allows an unlimited number of
clients to connect to the server.
62) Client limit period
This field allows you to set the client limit time period (in seconds). This along with the
client
limit
field above determine how many clients are allowed to make requests of this server.
63) Enable server authentication
This field enables the authentication of unsynchronized peers. If set to
yes, NTP only synchro-
nizes with peers that has been authenticated with the correct key ID.
64) Advertised precision
Sets the precision which the server advertises to the specified value. This should be a nega-
tive integer in the range -4 through -20.
65) Broadcast delay
This fields allows you to set a specified network delay time. Normally,
NTP automatically
compensates for the network delay between the broadcast/multicast server and the client. If
this calibration fails, the delay set here is used instead.
Configuring Client/Server Authentication
In order to use authentication, you must specify a key file. A key file contains the keys neces-
sary for NTP to decode encrypted NTP messages. To specify a key file, follow the steps below:
1. Enter the command as shown, at the system prompt:
ntpiconfig
The following menu appears:
NTP Startup Configuration
1) Response timeout : 0
2) Authentication delay : No
3) Authentication key file name : UNSET
4) NTP client mode : Ucast
5) Enable monitor : No
6) Enable NTP server : No
