A The key is a 1-to-8 character ASCII string. A key is formed from this by using the lower order 7 bits
of the ASCII representation of each character in the string, with zeroes being added on the right
when necessary to form a full width 56-bit key, in the same way that encryption keys are formed
from UNIX passwords.
M The key is a 1-to-32 character ASCII string, using the MD5 authentication scheme. Note that both
the keys and the authentication schemes (DES or MD5) must be identical between a set of peers
sharing the same key number.
The filegen Utility
Synopsis
filegen name [file filename ][
type typename ][link|nolink][enable|disable]
Description
This command helps in configuring the generation-file set
name. The generation-file sets provides a
mean for handling files that are continuously growing during the lifetime of a server. Server statistics
are a typical example for such files. The generation-file sets provide access to a set of files used to store
the actual data. At any time at most one element of the set is being written to. The
type given specifies
when and how data will be directed to a new element of the set. This way, information stored in elements
of a file set that are currently unused are available for administrational operations without the risk of
disturbing the operation of
xntpd. (Most important: they can be removed to free space for new data pro-
duced.) File names of set members are built from three elements. name is name of the statistic to be col-
lected. Currently only two kinds of statistics are supported: loopstats and peerstats.
Operands
file filename
Defines a filename string directly concatenated to the prefix mentioned above (no intervening /
(slash)) if prefix is defined in the statsdir statement.
type typename
This part reflects individual elements of a file set. It is generated according to the type of a file
set as explained below. A file generation set is characterized by its type. The following
typename s are supported:
none The file set is actually a single plain file.
pid One element of file set is used per incarnation of a
xntpd server. This type does
not perform any changes to file set members during runtime, however it provides an
easy way of separating files belonging to different xntpd server incarnations. The
set member file name is built by appending a dot . to the concatenated prefix and
filename strings, and appending the decimal representation of the process ID of the
xntpd server process, in for form: prefixfilename .pid.
day One file generation set element is created per day. The term day is based on Coor-
dinated Universal Time (UTC). A day is defined as the period between 00:00 and
24:00 UTC. The file set member suffix consists of a dot and a day specification in
the form YYYYMMDD. YYYY is a 4 digit year number (for example, 1992). MM is
a two digit month number. DD is a two digit day number. Thus, all information
written at December 10th, 1992 would end up in a file named
prefix filename
.19921210
week Any file set member contains data related to a certain week of a year. The term
week is defined by computing day of year modulo 7. Elements of such a file genera-
tion set are distinguished by appending the following suffix to the file set file name
base: A dot, a four digit year number, the letter W and a two digit week number.
For example, information from January, 10th 1992 would end up in a file with suffix
.1992W1.
month One generation file set element is generated per month. The file name suffix con-
sists of a dot, a four digit year number, and a two digit month.
year One generation file elment is generated per year. The file name suffix consists of a
dot and a 4 digit year number.
age This type of file generation sets changes to a new element of the file set every 24
hours of server operation. The file name suffix consists of a dot, the letter
a, and an
