MobiLink User property sheet: Connection tab

The Connection tab of the MobiLink User property sheet has the following components:

Protocol    Specify the communication protocol to use for synchronization. TCP/IP is used by default.

The settings you can specify on the Connection tab depend on the communication protocol you are using. Any additional parameters, such as buffer_size, can be set in the Advanced field.

For a complete list of parameters supported by each of the protocols, see or .

Host    The IP number or host name of the machine on which the MobiLink synchronization server is running. The default value is localhost. You can use localhost if the synchronization server is running on the same machine as the client.

For Windows CE, the default value is the value of ipaddr in the registry folder Comm\Tcpip\Hosts\ppp_peer. This allows a Windows CE device to connect to a MobiLink synchronization server executing on the desktop machine where the Windows CE device's cradle is connected.

For the Palm Computing Platform, the default value of localhost refers to the device. It is recommended that you specify an explicit host name or IP address.

Proxy host    Type the host name or IP address of the proxy server. The default value is localhost. This option is only available for HTTP and HTTPS synchronization.

URL suffix    Type the suffix to add to the URL on the first line of each HTTP request. The default value is MobiLink. This option is only available for HTTP and HTTPS synchronization.

When synchronizing through a proxy server, the suffix may be necessary in order to find the MobiLink synchronization server.

Automatic connection    The following options allow MobiLink clients running on Pocket PC 2002 or Windows desktop computers to connect through dial-up network connections.

When used with scheduling, your remote device can synchronize unattended. When used without scheduling, you can run dbmlsync without manually dialing a connection.

For more information about scheduling, see .

Network name    Specify the network name so that you can use MobiLink's auto-dial feature. This allows you to connect from a Pocket PC 2002 or Windows desktop computer without manually dialing. The name should be the network name that you have specified in the dropdown list in Settings > Connections > Connections (Pocket PC) or Network & Dialup Connections (Windows).

Network connect timeout    When you specify a network name, you can optionally specify a timeout after which the dial-up fails. This feature applies only to Pocket PC 2002. (On Windows, you can control this feature by configuring the connection profile.) The default is 120 seconds.

Leave open    When you supply a network name, you can optionally specify whether the connection should be left open (1) or closed (0) after synchronization finishes. By default, the connection is closed.

Security    These options allow you to use a cipher suite to encrypt all communication through this connection. You can provide information about the certificate used to authenticate the server in the fields below for both the elliptic-curve and RSA ciphers.

Enable Certicom security    Select this option to encrypt all communication through this connection. You can use the elliptic-curve or RSA cipher. By default, elliptic curves are used.

Separately licensable option required 

Transport-layer security requires that you obtain the separately-licensable SQL Anywhere Studio security option and is subject to export regulations.

To order this component, see .

For more information about security, see .

Advanced    Type any additional connection parameters in this field, entering them in the form parameter=value, with multiple parameters separated by semicolons. For example, to set the maximum body size for a fixed content length message, and to instruct the client to attempt to use the same TCP/IP connection for all HTTP requests in a synchronization, you would enter the following in the Advanced field:

buffer_size=58000;persistent=TRUE

For a complete list of connection parameters you can enter in this field, see .

Note 

You can set connection parameters for synchronization in several ways.

For information about how dbmlsync resolves conflicting options, see .

If a field is blank on the Connection tab of the MobiLink User property sheet, the MobiLink user may be inheriting the connection parameter setting from the synchronization subscription. You should only supply connection parameters on the Connection tab of the MobiLink User property sheet if you want to override the publication's settings.
