=head1 NAME
|
||
|
|
|
||
|
|
kaserver.DB0 and kaserver.DBSYS1 - Contain the Authentication Database and associated log
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The kaserver.DB0 file contains the Authentication
|
||
|
|
Database, which records server encryption keys and an encrypted form of all
|
||
|
|
user passwords. The Authentication Server (B<kaserver> process)
|
||
|
|
uses the information in the database to enable secured communications between
|
||
|
|
AFS server and client processes.
|
||
|
|
|
||
|
|
The kaserver.DBSYS1 file is a log file in which the
|
||
|
|
Authentication Server logs each database operation before performing
|
||
|
|
it. When an operation is interrupted, the Authentication Server replays
|
||
|
|
the log to complete the operation.
|
||
|
|
|
||
|
|
Both files are in binary format and reside in the /usr/afs/db
|
||
|
|
directory on each of the cell's database server machines. When the
|
||
|
|
Authentication Server starts or restarts on a given machine, it establishes a
|
||
|
|
connection with its peers and verifies that its copy of the database matches
|
||
|
|
the copy on the other database server machines. If not, the
|
||
|
|
Authentication Servers call on AFS's distributed database technology,
|
||
|
|
Ubik, to distribute to all of the machines the copy of the database with the
|
||
|
|
highest version number.
|
||
|
|
|
||
|
|
Always use the commands in the kas suite to administer the
|
||
|
|
Authentication Database. It is advisable to create an archive copy of
|
||
|
|
the database on a regular basis, using a tool such as the UNIX B<tar>
|
||
|
|
command.
