houdini_license_sever start and off

Start/stop the license server

The license server is called sesinetd.

You must have "admin" rights (root, sudo) to be able to stop/start the license server.

Windows

You can start and stop the HoudiniLicenseServer in the Services area of Windows.

1. Control Panel -> Administrative Tools -> Services
2. The service HoudiniLicenseServer controls the license server program sesinetd.

Linux

1. Usage: /etc/init.d/sesinetd {start|stop}

Mac

1. Launch the Terminal from Utilities
2. To stop the license server: sudo launchctl unload /Library/LaunchDaemons/com.sidefx.sesinetd.plist
3. To start the license server: sudo launchctl load /Library/LaunchDaemons/com.sidefx.sesinetd.plist

If you receive an error saying /Library/LaunchDaemons/com.sidefx.sesinetd.plist: No such file or directory, please reinstall Houdini and choose Commercial Licensing. This will install the necessary license server files.

When you restart the license server software on a centralized server machine, the remote clients will not lose their sessions for approximately 5 minutes of a failed heartbeat (or license check).

To control the behavior of sesinetd:

The file that specifies the behaviour of sesinetd is named sesinetd.options. Put the following options in sesinetd.options

• On Linux this file is located in /usr/lib/sesi
• On Windows, this file must reside in C:WindowsSystem32
• On Mac, this file is in /Applications/Houdini/Houdini18.0.xxx/Frameworks/Houdini.framework/Versions/Current/Resources/houdini/sbin

                 4 = debug
    -z size    Specify maximum log file size  [default: 1M]
               e.g. 0.5M = .5 Mb
                    32k  = 32 Kb
                    5000 = 5000 bytes
