Internet Service Manager Help

## FTP Service Properties

You use the Service property sheet to control who can use your server and specify the account used for anonymous client requests to log on to the computer. Most Internet sites allow anonymous logons. If you allow anonymous logons, then all user permissions for the user, such as permission to access information, will use the IUSR_computername account. To use your current security system to control information access, change the anonymous logon account from IUSR_computername to an existing account on your network.

This property sheet also sets the comment in the Internet Service Manager Report view.

### TCP Port

Determines the port on which the FTP service is running. The default is port 21. You can change the port to any unique TCP port number. For a new port number to take effect, you must restart your computer.

### Connection Timeout

Sets the length of time in seconds before the server disconnects an inactive user. It is recommended that you not set this number lower than 100 seconds. The maximum you can set is 32,767 seconds. This value ensures that all connections are closed if the FTP protocol fails to close a connection.

### Maximum Connections

Sets the maximum number of simultaneous connections to the server.

### Allow Anonymous Connections

Sets the Windows NT user account to use for permissions of all anonymous connections. By default, Internet Information Server creates and uses the account IUSR_computername for all anonymous logons. Note that the password is used only within Windows NT; anonymous users do not log on using this user name and password.

Typically, anonymous FTP users will use "anonymous" as the user name and their e-mail address as the password. The FTP service then uses the IUSR_computername account as the logon account for permissions.

When you installed Internet Information Server, Setup created the account IUSR_computername in the Windows NT User Manager for Domains and in the Internet Service Manager. This account was assigned a random password. The password for this account must be the same, both in Internet Service Manager and in the Windows NT User Manager for Domains. If you change the password, you must change it in both places and make sure it matches.

Note: This account must have a password. You cannot assign a blank password.

The IUSR_computername is granted Log on locally user rights by default. This right is necessary as long as you want to grant anonymous logon access to your site.

Note: To grant access to a specific user, you must grant that user Log on locally rights in Windows NT Server User Manager for Domains.

### Allow only anonymous connections

Select this box to all only anonymous connections. With this box selected, users cannot logon with user names and passwords. This prevents access by using an account with administrative permission; only the account specified for anonymous access is granted access. This also prevents clear text transmission of passwords.
