Send-IM ConfigurationThe cmdlet accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the cmdlet, access to these internal properties is provided through the Config method.
XMPP Configuration Settings
|AccessToken: The OAuth access token used for authentication.Specifies the OAuth access token used during authentication. This can be used when connecting to Facebook or Windows Live Messenger.|
|BlockSize: Specifies the block size for file transfers.The size in bytes of the block size used when sending files. The default value is 4096. Increasing this value may improve performance. However, some servers may not support larger block sizes.|
|ClientId: The OAuth client Id used for authentication.Specifies the OAuth client Id used during authentication. This can be used when connecting to Facebook. Windows Live Messenger does not require this value.|
|MessageXML: Returns the last root-level element received by the component. This returns the last root-level element received by the component. This could be a message, iq, presence, or any other element type.|
|Overwrite: Specifies whether or not to overwrite received files. The default value is false. If set to true, the cmdlet will overwrite the existing files in LocalDirectory if another file with the same name is received. This is only applicable when receiving file transfers.|
|ParseHTML: Tells XMPP whether or not to parse MessageHTML when it's set. If ParseHTML is true, the cmdlet will take any value sent to MessageHTML, compute a plaintext version of the text, and put it into the MessageText property.|
|RetrieveRoster: Whether to automatically retrieve the roster when logging in. When this configuration setting is set to True (default), the cmdlet will automatically retrieve the roster from the server when logging in. Setting this to False will cause the cmdlet to not request the roster, which can be useful when interacting with some non-standard XMPP servers.|
|SendSubscriptionResponse: Determines whether a response will be sent to a Subscription Request. When set to true, a response will be sent to a subscription request based upon the Accept parameter value of the SubscriptionRequest event. When set to false, a response will not be sent. Therefore a response can be created and sent using SendCommand outside of the SubscriptionRequest event. The default value is true.|
|UseCompression: Specified whether or not stream compression is used. The default value is false. If set to true, the cmdlet will use stream compression when communicating with the IMServer.|
IPPort Configuration Settings
|ConnectionTimeout: Sets a separate timeout value for establishing a connection.When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the cmdlet will use Timeout for establishing a connection and transmitting/receiving data.|
|FirewallAutoDetect: Tells the cmdlet whether or not to automatically detect and use firewall system settings, if available.This is the same as FirewallAutoDetect. This setting is provided for use by cmdlets that do not directly expose Firewall properties.|
Name or IP address of firewall (optional).If a FirewallHost is given, requested connections will be authenticated through the specified firewall
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
NOTE: This is the same as FirewallHost. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
Password to be used if authentication is to be used when connecting through the firewall.If FirewallHost is specified, the FirewallUser and FirewallPassword settings
are used to connect and authenticate to the given firewall. If the authentication fails, the cmdlet throws an exception.
NOTE: This is the same as FirewallPassword. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
The TCP port for the FirewallHost;.Note that the FirewallPort is set automatically when FirewallType is set to a valid value.
NOTE: This is the same as FirewallPort. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
Determines the type of firewall to connect through.The appropriate values are as follows:
NOTE: This is the same as FirewallFirewallType. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
A user name if authentication is to be used connecting through a firewall.If the FirewallHost is specified, the FirewallUser and FirewallPassword
settings are used to connect and authenticate to the Firewall. If the authentication fails, the cmdlet throws an exception.
NOTE: This is the same as FirewallUser. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.When set, TCPKeepAlive will automatically be set to true.
A TCP keep-alive packet will be sent after a period of inactivity as
defined by KeepAliveTime. If no acknowledgement is received from the remote host the keep-alive packet
will be re-sent. This setting specifies the interval at which the successive keep-alive packets are sent in milliseconds.
This system default if this value is not specified here is 1 second.
Note: This value is not applicable in Java or MAC.
The inactivity time in milliseconds before a TCP keep-alive packet is sent.When set, TCPKeepAlive will automatically be set to true.
By default the operating system will determine the
time a connection is idle before a TCP keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many
cases a shorter interval is more useful. Set this value to the desired interval in milliseconds.
Note: This value is not applicable in Java.
When set to True, connections are terminated gracefully.This property controls how a connection is closed. The default is True.
In the case that Linger is True (default), there are two scenarios for determining how long the connection will linger. The first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP protocol timeout expires.
In the second scenario, LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the cmdlet returns control immediately, the system could hold system resources until all pending data is sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.
|LingerTime: Time in seconds to have the connection linger. LingerTime is the time, in seconds, to leave the socket connection linger. This value is 0 by default, which means it will use the default IP protocol timeout.|
The name of the local host through which connections are initiated or accepted.
The LocalHost setting contains the name of the local host
as obtained by the gethostname() system call, or if the
user has assigned an IP address, the value of that address.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the cmdlet initiate connections (or accept in the case of server cmdlets) only through that interface.
If the cmdlet is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).
The port in the local host where the cmdlet binds.
This must be set before a connection is
attempted. It instructs the cmdlet to bind to a specific
port (or communication endpoint) in the local machine.
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
The maximum amount of data to accumulate when no EOL is found.MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.
|MaxTransferRate: The transfer rate limit in bytes per second.This setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default this is not set and there is no limit.|
A semicolon separated list of hosts and IPs to bypass when using a proxy.This setting optionally specifies a semicolon separated list of hostnames or IP addresses to bypass when a proxy is in use.
When requests are made to hosts specified in this property the proxy will not be used. For instance:
Determines whether or not the keep alive socket option is enabled.If set to true, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically
to maintain the connection. Set KeepAliveTime and KeepAliveInterval to
configure the timing of the keep-alive packets.
Note: This value is not applicable in Java.
Whether or not to delay when sending packets.
When true, the socket will send all data that is ready to send at once. When
false, the socket will send smaller buffered packets of data at small intervals.
This is known as the Nagle algorithm.
By default, this config is set to false.
Whether to use IPv6.When set to 0 (default), the cmdlet will use IPv4 exclusively.
When set to 1, the cmdlet will use IPv6 exclusively. To instruct the cmdlet to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0.
Possible values are:
Socket Configuration Settings
Determines whether timeouts are inactivity timeouts or absolute timeouts.If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds
will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.
Note: This option is not valid for UDP ports.
|FirewallData: Used to send extra data to the firewall.When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).|
The size in bytes of the incoming queue of the socket.
This is the size of an internal queue in the TCP/IP stack.
You can increase or decrease its size depending on the amount
of data that you will be receiving. Increasing the value of the
InBufferSize setting can provide significant improvements in
performance in some cases.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the cmdlet is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
The size in bytes of the outgoing queue of the socket.This is the size of an internal queue in the TCP/IP stack.
You can increase or decrease its size depending on the amount
of data that you will be sending. Increasing the value of the
OutBufferSize setting can provide significant improvements in
performance in some cases.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the cmdlet is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Base Configuration Settings
Tells the cmdlet whether or not to use the system security libraries or an internal implementation.
By default the cmdlet will use the system security libraries to perform cryptographic functions.
When set to False calls to unmanaged code will be made. In certain environments this is not desirable.
To use a completely managed security implementation set this setting to True.
Setting this to True tells the cmdlet to use the internal implementation
instead of using the system's security API.
Note: This setting is static. The value set is applicable to all cmdlets used in the application.
When this value is set the product's system DLL is no longer required as a reference, as all unmanaged code is stored in that file.
