We use a TCP connection for the communication between the ‘Mac’ agent and server.
In order to work properly, the TCP port must be opened on server firewall.
By default, UserLock uses the port 50555 to listen to the Mac Agent. You can check this in the Command Prompt:
netstat -an | find “50555”
Change the port number
If you need to change the port number, you must do it with both primary and backup servers. This will require a restart of the UserLock service in order for the change to be applied.
From the Console
Open the Advanced Settings for server (shortcut F7), and adjust the variable “MacListeningPort”.
The following snippet can help you:
Set-USerLockServerConfiguration -UserLockServerName $ServerName -Property MacListeningPort -Value $newPortForMac -Force
Configure the firewall
You must also add a firewall rule (inbound only) with:
- Protocol Type : TCP
- Local port: specific port (the one you setup, or 50555 by default).
