14.4.4 Resetting everything
You can usually remove the local UIM serial numbers with the uimreset -l command. You
can remove both the local UIM serial numbers and corresponding entries in the UIM server
database with the uimreset -r command.
If the local UIM database is corrupted, the uimreset command may fail. In this rare case you
can delete the files in directory /usr/z1090/uim. However, the previous UIM serial for that
client will still be provided by a UIM server (if the client XML file is configured for connection to
the server, of course). In this case, the uimreset -r command may be used to remove the
relevant entry from the UIM server database if that is desired.
The UIM server may be reinitialized by removing everything in the UIMserver subdirectory in
the home directory of the Linux userid that runs the UIM server. This is a drastic step, of
course, and should not be done in normal operational environments. If the UIMserver
directory is cleared, some of the entries will be restored by future client connections in which
the client still has previous UIM local data.
The client configuration file may be restored to its original state (which does not reference any
remote servers) by using the Factory Reset option with the clientconfig command.
14.4.5 SafeNet module restarts
There are two SafeNet functions involved with zPDT. One is the license server that we
discuss in this chapter. The other is a daemon (“token driver”) that communicates with tokens
(in USB ports). After zPDT is installed, both these functions are started automatically when
Linux is booted. Changing the license server XML files requires restarting the license server.
It should not be necessary to restart the token driver except in unusual situations.
The commands to restart each function are:
$ su (change to root)
# cd /opt/safenet_sentinel/common_files/sentinel_usb_daemon
# ./load_daemon.sh restart (or status or stop or start)
# cd /opt/safenet_sentinel/common_files/sentinel_keys_server
# ./loadserv restart (or status or stop or start)
14.5 Glossary
The license server and UIM server and functions can be confusing. The glossary presented
here may help the reader through some of the confusion.
zPDT - The basic product. Also known as a 1090 or 1091 or part of a complete RDzUT
package.
SafeNet - The company that provides the USB keys and the software that directly supports
them. This includes the USB driver, the license manager, and a web interface to the
license manager.
SafeNet Sentinel Key - The USB “token” from the SafeNet company. This token provides
zPDT license information.
Token - Another term for a SafeNet Sentinel Key. The terms token, key, SafeNet key, and
Sentinel key are used interchangeably.
