On Windows, License Manager server runs as the synd service, synlm.
On UNIX, License Manager runs as the synd daemon.
Windows
License Manager server, synd, is a background process that runs on license servers and on machines that have local licensing. Synd runs as the service synlm. To start or stop License Manager server, you must have administrator privileges.
Options
synd [-h] [-q] [-r] [-rs] [-u] [-v] [-x]
-h
Display a list of synd options.
-q
Stop the synlm service.
-r
Register the synlm service.
-rs
Register the synlm service (if it is not already registered) and then start it.
-u username/password
Register synd with the specified username and password. Used with -r and -rs. If -u is not specified, the service runs using the local system account. If using clear text, separate the username and password with a forward slash. Optionally, you can run setruser -n and pass the encoded output. (See setruser utility.) The account can be on the local machine or it can be a domain controller account. If the latter, use either user_name@domain_name/password or domain_name\user_name/password. See Registering License Manager server to run as a specific user for more information.
-v
Display the synd version.
-x
Unregister the synlm service. If the service is running, -x will stop it and then unregister it.
Starting License Manager server automatically
License Manager server is started automatically when you install Synergy/DE Core Components.
Starting License Manager server manually
To start License Manager server manually, do either of the following. This will start the service synlm, which starts synd.
- In the Windows Services console, select Synergy/DE License Manager and click the Start button.
- At a command prompt enter
net start synlm
If you receive the error “Could not start the Synergy/DE License Manager service. The system could not find the file specified,” you should unregister and reregister the synlm service. After reregistering, try starting synlm again.
|
The License Manager service synlm always logs its version and start/stop time to the Windows application event log, which can be viewed with the Windows Event Viewer. For information on extended event logging for the synlm service, see Error logging. |
Stopping License Manager server
To stop (but not unregister) the synlm service, do one of the following:
- In the Windows Services console, select Synergy/DE License Manager and click the Stop button.
- At a command prompt enter
synd -q
- At a command prompt enter
net stop synlm
To stop and unregister the synlm service, at a command prompt enter
synd -x
Registering License Manager server to run as a specific user
By default, synd runs under the local system account. You can specify a different account using the -u option. The account used to run synd must have administrator privileges as well as the user right “Log on as a service.” Because License Manager server is registered and started automatically, you’ll need to stop and unregister the service, then reregister it with the -u option. For example,
synd -x synd -r -u username/password net start synlm
Optionally, you could register and start the service in one step by using -rs instead of -r.

Another way to specify the user account for a service is from the Windows Services console (which can be accessed from Control Panel > Administrative Tools > Services). Locate Synergy/DE License Manager in the list of services, right-click on it, and select Properties from the context menu. Go to the Log On tab and specify the account and password. Then click Apply. |
UNIX
The License Manager daemon, synd, is a background process that must be running in order for Synergy/DE products to run. It provides licensing and SEND/RECV message services to Synergy/DE products. It is initially started when you execute install.sde.
Options
When run with no options, synd starts the License Manager daemon.
synd [-bsize] [-h] [-p] [-q] [-v]
-bsize
Change the message queue buffer size. The default is 4096. Use -b if you SEND/RECV messages larger than 4096 bytes.
-h
Display a list of synd options.
-p
Ping the License Manager daemon to see if it is responding; also displays synd version.
-q
Stop the License Manager daemon. You must be UID=0 to do this.
-v
Display the synd version.
Starting License Manager automatically
To start License Manager automatically when the system reboots, add the full path name of synd to your system start-up file (e.g., rc or systemd). This ensures that synd will restart automatically if your system goes down. Consult your UNIX system administrator manual for more information about starting multi-user daemons.
|
Because synd needs to contact the Synergy License Web Service, you should ensure that all networking has been started (e.g., named, dnsmasq, networkmanager, winbindd, nmdb) before synd starts. |
For example, on some machines you might add this line to the /etc/rc file:
/usr/synergyde/lm/synd
Starting License Manager manually
To start License Manager manually, restart synd without rebooting or reinstalling. For example, on some machines you might enter
/usr/synergyde/lm/synd
Stopping License Manager
To stop License Manager, you must be UID=0. Use this command:
synd -q
