You can gather version information for Sentinel .jar files for troubleshooting purposes:
Log in to the Sentinel server as an administrator.
Go to the /opt/novell/sentinel/bin directory.
At the command line, specify the ./versionreader.sh <path/jar file name>.
Running the script without any arguments gives the version of the installed Sentinel server. For more information on the arguments that can be used, use the --help command.
