1. Start the Services for UNIX Administration tool, and then click Password Synchronization.
   
   Note If Password Synchronization does not appear under the Services for UNIX [local] node, you must install the Password Synchronization feature. This feature is not installed if you perform a typical Windows Services for UNIX 3.5 installation. To install the Password Synchronization feature, follow these steps:
   1. Click Start, click Control Panel, and then double-click Add or Remove Programs.
   2. Click Microsoft Windows Services for UNIX, and then click Change.
   3. In the Microsoft Windows Services for UNIX Maintenance Wizard, click Next.
   4. Click Add or remove, click Next, click Password Synchronization, click Will be installed on local hard drive, and then click Next.
   5. Click Finish, and then restart your computer if you are prompted to do this.
2. In the Port number box, type the port number that you want the Password Synchronization feature to use, and then click Apply.

The RSH server feature

To enable external access to the Windows Services for UNIX 3.5 RSH server, you must open the following port.

Service or feature	Protocol	Port
RSH server	TCP	514

The Services for UNIX Administration tools

To enable access to Windows Services for UNIX 3.5 by using the Services for UNIX Administration tool or by using the Services for UNIX command-line tools, you must enable file and printer sharing in the Windows Firewall. To do this, follow these steps:

1. Click Start, click Run, type firewall.cpl, and then click OK.
2. Click the Exceptions tab, click to select the File and Printer Sharing check box, and then click OK.

The Interix daemons

By default, the Microsoft Interix daemons are not enabled. When you enable the Interix daemons by using the Inetd.conf file, you must also open the corresponding port in the Windows Firewall. You can determine the daemons that are configured to run by examining the etc/inetd.conf file. You can determine the corresponding port numbers to open for each service by examining the etc/services file. To open a port in the Windows Firewall, follow these steps:

1. Click Start, click Run, type firewall.cpl, and then click OK.
