Class Snpps

java.lang.Object
  ipworksssl.Snpps

public class Snpps
extends java.lang.Object

The SNPPS Bean is used to send pages through the internet using the SNPP protocol.

It is a client implementation of Simple Network Paging Protocol Version 3 as specified in RFC 1861. Service extensions level 2 are supported intrinsically and the user can access all of level 3 extensions.

SNPP allows for immediate notification of message delivery, gives absolute flexibility over the content sent to the recipient, allows the specification of multiple choice responses, etc.

To send a message the ServerName , recipient's PagerId and Message properties should be filled out (at a minimum). The Send method is then used to deliver the message.

The server's response is given in the PITrail events and by the LastReply property. Customized commands may be sent using the Command property.

Optional properties include: CallerId , ServerPort and LocalHost

getSSLServerCert

public Certificate getSSLServerCert()

The server certificate for the last established connection.

SSLServerCert contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

getSSLStartMode

public int getSSLStartMode()

Determines how the bean starts the SSL negotiation.

The SSLStartMode property may have one of the following values:

0 (sslAutomatic - default)

If the remote port is set to the standard plaintext port of the protocol (where applicable), the bean will behave the same as if SSLStartMode is set to sslExplicit . In all other cases, SSL negotiation will be implicit ( sslImplicit ).

1 (sslImplicit)

The SSL negotiation will start immediately after the connection is established.

2 (sslExplicit)

The bean will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS.

3 (sslNone)

No SSL negotiation, no SSL security. All communication will be in plaintext mode.

setSSLStartMode

public void setSSLStartMode(int SSLStartMode)
                     throws IPWorksSSLException

Determines how the bean starts the SSL negotiation.

The SSLStartMode property may have one of the following values:

0 (sslAutomatic - default)

Throws:

IPWorksSSLException

getTimeout

public int getTimeout()

A timeout for the bean.

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the bean will wait for the operation to complete before returning control.

The bean will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the bean throws an exception.

Please note that by default, all timeouts are inactivity timeouts , i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

Optionally, the behavior of the bean may be changed to absolute timeouts , i.e. the bean will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by the ipworksssl.Snpps#config configuration setting.

The default value for the {@link ipworksssl.Snpps#getTimeout Timeout} property is 60 (seconds).

setTimeout

public void setTimeout(int timeout)
                throws IPWorksSSLException

A timeout for the bean.

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the bean will wait for the operation to complete before returning control.

The bean will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the bean throws an exception.

Please note that by default, all timeouts are inactivity timeouts , i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

Optionally, the behavior of the bean may be changed to absolute timeouts , i.e. the bean will wait for a maximum of Timeout seconds since the beginning of the operation, without extending the timeout period during communications.

This behavior is controlled by the ipworksssl.Snpps#config configuration setting.

The default value for the {@link ipworksssl.Snpps#getTimeout Timeout} property is 60 (seconds).

Throws:

IPWorksSSLException

config

public java.lang.String config(java.lang.String configurationString)
                        throws IPWorksSSLException

Sets or retrieves a ipworksssl.Snpps#config configuration setting.

{@link ipworksssl.Snpps#config Config} is a generic method available in every bean. It is used to set and retrieve {@link ipworksssl.Snpps#config configuration settingsfor the bean.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the bean, access to these internal properties is provided through the {@link ipworksssl.Snpps#config Config} method.

To set a configuration setting named PROPERTY , you must call Config("PROPERTY=VALUE") , where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a {@link ipworksssl.Snpps#config configuration setting, you must call Config("PROPERTY") . The value will be returned as a string.

The bean 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 bean, access to these internal properties is provided through the {@link ipworksssl.Snpps#config Config} method.

SNPP Configuration Settings

LoginID

Login ID used to authenticate with an SNPP server

This is used to specify the Login ID to be used when authentication is required by the SNPP server.

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 bean will use {@link ipworksssl.Snpps#getTimeout Timeout} for establishing a connection and transmitting/receiving data.

FirewallAutoDetect

Tells the bean whether or not to automatically detect and use firewall system settings, if available

This is the same as AutoDetect . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallHost

Name or IP address of firewall (optional)

If a {@link ipworksssl.Snpps#config is given, requested connections will be authenticated through the specified firewall when connecting.If the {@link ipworksssl.Snpps#config setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the {@link ipworksssl.Snpps#config setting is set to the corresponding address. If the search is not successful, an error is returned.

NOTE: This is the same as Host . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallListener

If true, the component binds to a SOCKS firewall as a server (IPPort only)

This entry is for IPPort only and does not work for other components that descend from IPPort.If this entry is set, the bean acts as a server. {@link ipworksssl.Snpps#getRemoteHost RemoteHost} and {@link ipworksssl.Snpps#getRemotePort RemotePort} are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore {@link ipworksssl.Snpps#getRemoteHost RemoteHost} , and it is recommended that {@link ipworksssl.Snpps#getRemoteHost RemoteHost} be set to empty string in this case.

{@link ipworksssl.Snpps#getRemotePort RemotePort} is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the {@link ipworksssl.SnppsConnectionStatusEvent ConnectionStatus} event.

The connection to the firewall is made by calling the {@link ipworksssl.Snpps#connect Connect} method.

FirewallPassword

Password to be used if authentication is to be used when connecting through the firewall

If {@link ipworksssl.Snpps#config is specified, the {@link ipworksssl.Snpps#config and {@link ipworksssl.Snpps#config settings are used to connect and authenticate to the given firewall. If the authentication fails, the bean throws an exception.NOTE: This is the same as Password . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallPort

The TCP port for the FirewallHost;

Note that the {@link ipworksssl.Snpps#config is set automatically when {@link ipworksssl.Snpps#config is set to a valid value.NOTE: This is the same as Port . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallType

Determines the type of firewall to connect through

The appropriate values are as follows:

0

No firewall (default setting).

1

Connect through a tunneling proxy. {@link ipworksssl.Snpps#config is set to 80.

2

Connect through a SOCKS4 Proxy. {@link ipworksssl.Snpps#config is set to 1080.

3

Connect through a SOCKS5 Proxy. {@link ipworksssl.Snpps#config is set to 1080.

NOTE: This is the same as FirewallType . This setting is provided for use by beans that do not directly expose Firewall properties.

FirewallUser

A user name if authentication is to be used connecting through a firewall

If the {@link ipworksssl.Snpps#config is specified, the {@link ipworksssl.Snpps#config and {@link ipworksssl.Snpps#config settings are used to connect and authenticate to the Firewall. If the authentication fails, the bean throws an exception.NOTE: This is the same as User . This setting is provided for use by beans that do not directly expose Firewall properties.

KeepAliveTime

The inactivity time in milliseconds before a TCP keep-alive packet is sent

When set, {@link ipworksssl.Snpps#config 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.

KeepAliveInterval

The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received

When set, {@link ipworksssl.Snpps#config will automatically be set to true. A TCP keep-alive packet will be sent after a period of inactivity as defined by {@link ipworksssl.Snpps#config . 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.

Linger

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 {@link ipworksssl.Snpps#config 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, {@link ipworksssl.Snpps#config is a positive value, the system will attempt to send pending data until the specified {@link ipworksssl.Snpps#config 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 bean 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.

LocalHost

The name of the local host through which connections are initiated or accepted

The {@link ipworksssl.Snpps#getLocalHost 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 bean initiate connections (or accept in the case of server beans) only through that interface.

If the bean is connected, the {@link ipworksssl.Snpps#getLocalHost 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).

LocalPort

The TCP port in the local host where the bean binds

This must be set before a connection is attempted. It instructs the bean 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 {@link ipworksssl.Snpps#getLocalPort LocalPort} after the connection is established.

{@link ipworksssl.Snpps#getLocalPort 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.

MaxLineLength

The maximum amount of data to accumulate when no EOL is found

{@link ipworksssl.Snpps#config is the size of an internal buffer, which holds received data while waiting for an {@link ipworksssl.Snpps#getEOL EOL} string.If an {@link ipworksssl.Snpps#getEOL EOL} string is found in the input stream before {@link ipworksssl.Snpps#config bytes are received, the {@link ipworksssl.SnppsDataInEvent DataIn} event is fired with the EOL parameter set to True, and the buffer is reset.

If no {@link ipworksssl.Snpps#getEOL EOL} is found, and {@link ipworksssl.Snpps#config bytes are accumulated in the buffer, the {@link ipworksssl.SnppsDataInEvent DataIn} event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for {@link ipworksssl.Snpps#config is 256 bytes. The default value is 2048 bytes. The maximum value is 65536 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.

TCPKeepAlive

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 {@link ipworksssl.Snpps#config and {@link ipworksssl.Snpps#config to configure the timing of the keep-alive packets.Note: This value is not applicable in Java.

UseIPv6

Whether or not to use IPv6

By default, the component expects an IPv4 address for local and remote host properties, and will create an IPv4 socket. To use IPv6 instead, set this to True.

CloseStreamAfterTransfer

If true, the component will close the upload or download stream after the transfer

This setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. In order to keep streams open after the transfer of data, set this to False. the default value is True.

TcpNoDelay

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.

SSL Configuration Settings

ReuseSSLSession

Determines if the SSL session is reused

If set to true, the component will reuse the context if and only if the following criteria are met:

• The target host name is the same.
• The system cache entry has not expired (default timeout is 10 hours).
• The application process that calls the function is the same.
• The logon session is the same.
• The instance of the component is the same.

SSLCipherStrength

The minimum cipher strength used for bulk encryption

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the {@link ipworksssl.SnppsSSLStatusEvent SSLStatus} event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the {@link ipworksssl.Snpps#config config setting.

SSLEnabledProtocols

Used to enable/disable the supported security protocols

Used to enable/disable the supported security protocols.Not all supported protocols are enabled by default (the value of this setting is 192). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.2

3072 (Hex C00)

TLS1.1

768 (Hex 300)

TLS1

192 (Hex C0) (Default)

SSL3

48 (Hex 30)

SSL2

12 (Hex 0C)

Please note that although a number of sites still support SSL2, it is usually a good idea to disable it because of potential security vulnerabilities.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the {@link ipworksssl.Snpps#config config setting.

TLS 1.1 and TLS1.2 support are only available starting with Windows 7.

SSLProvider

The name of the security provider to use

Change this setting to use security providers other than the system default.Use this setting with caution. Disabling SSL security or pointing to the wrong provider could potentially cause serious security vulnerabilities in your application.

The special value "*" (default) picks the default SSL provider defined in the system.

Note: On Windows systems, the default SSL Provider is "Microsoft Unified Security Protocol Provider" and cannot be changed.

SSLSecurityFlags

Flags that control certificate verification

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:

0x00000001

Ignore time validity status of certificate.

0x00000002

Ignore time validity status of CTL.

0x00000004

Ignore non-nested certificate times.

0x00000010

Allow unknown Certificate Authority.

0x00000020

Ignore wrong certificate usage.

0x00000100

Ignore unknown certificate revocation status.

0x00000200

Ignore unknown CTL signer revocation status.

0x00000400

Ignore unknown Certificate Authority revocation status.

0x00000800

Ignore unknown Root revocation status.

0x00008000

Allow test Root certificate.

0x00004000

Trust test Root certificate.

0x80000000

Ignore non-matching CN (certificate CN not-matching server name).

This functionality is currently not available in Java or when the provider is OpenSSL.

SSLContextProtocol

The protocol used when getting an SSLContext instance

Possible values are SSL, SSLv2, SSLv3, TLS and TLSv1. Use it only in case your security provider does not support TLS. This is the parameter "protocol" inside the SSLContext.getInstance(protocol) call.

SSLTrustManagerFactoryAlgorithm

The algorithm to be used to create a TrustManager through TrustManagerFactory

Possible values include SunX509. This is the parameter "algorithm" inside the TrustManagerFactory.getInstance(algorithm) call.

SSLEnabledCipherSuites

The cipher suite to be used in an SSL negotiation

The enabled cipher suites to be used in SSL negotiation.By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the component will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values:

 obj.config("SSLEnabledCipherSuites=*");
 obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA");

SSLAlgorithmList

A string that controls the cipher algorithms to be used by SSL

This configuration option takes a semicolon (;) delimited list of cipher algorithms to specify what algorithms may be used by SSL. This option can be used in conjunction with SSLEnabledProtocols to control which ciphers are used.For example:

Socket Configuration Settings

AbsoluteTimeout

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).

InBufferSize

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 bean is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize

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 bean 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

GUIAvailable

Tells the bean whether or not a message loop is available for processing events

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The bean will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.In some non-GUI applications an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GuiAvailable to false will ensure that the bean does not attempt to process external events.

UseDaemonThreads

Whether threads created by the bean are daemon threads

If set to True, when the bean creates a thread the thread's Daemon property will be explicitly set to True. By default this setting is False and the bean will not set the Daemon property on the created thread.

Throws:

IPWorksSSLException

connect

public void connect()
             throws IPWorksSSLException

Connects to an SNPP server.

This method connects to the SNPP server. Any number of messages can later be sent using the Send method.

Example (Send Page)

 SNPPControl.ServerName = "MyServer"
 SNPPControl.CallerId = "SenderPagerNumber"
 SNPPControl.PagerId = "RecipientPagerNumber"
 SNPPControl.Message = "Hello, this is my message!"
 SNPPControl.Connect()
 SNPPControl.Send()
 SNPPControl.Disconnect() 

Throws:

IPWorksSSLException

disconnect

public void disconnect()
                throws IPWorksSSLException

Disconnects from an SNPP gateway.

This method disconnects from the SNPP gateway.

Throws:

IPWorksSSLException

doEvents

public void doEvents()
              throws IPWorksSSLException

Processes events from the internal message queue.

When DoEvents is called, the bean processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Throws:

IPWorksSSLException

interrupt

public void interrupt()
               throws IPWorksSSLException

Interrupt the current method.

If there is no method in progress, Interrupt simply returns, doing nothing.

Throws:

IPWorksSSLException

reset

public void reset()
           throws IPWorksSSLException

Resets the server state created during the connection.

This method resets the server state created during the connection, so that a new message may be sent to the gateway using the already established connection.

Throws:

IPWorksSSLException

send

public void send()
          throws IPWorksSSLException

Sends the current message.

This method sends the current message. If the bean is not already connected to the SNPP server then a connection is created. Then the bean attempts to deliver the current message.

Example (Send Page)

 SNPPControl.ServerName = "MyServer"
 SNPPControl.CallerId = "SenderPagerNumber"
 SNPPControl.PagerId = "RecipientPagerNumber"
 SNPPControl.Message = "Hello, this is my message!"
 SNPPControl.Send() 

Throws:
