SysLog Class
Properties Methods Events Config Settings Errors
The Syslog class is used to send and receive network system log packets.
Syntax
ipworks.syslog()
Remarks
The Syslog class implements a lightweight BSD syslog client as specified in RFC 3164 (UDP), RFC 5425 (SSL/TLS), and RFC 6587 (TCP). The class is used to send and receive BSD system network logging packets.
The first step in using the Syslog class is to set LocalHost and LocalPort to the interface and port on which the host will be receiving syslog packets, then set Active to True. For each packet, the class will parse the headers and message and fire a PacketIn event.

SysLog.Active Property
Indicates whether the class is active.
Syntax
isActive(): boolean;
Default Value
FALSE
Remarks
This property indicates whether the class is currently active and can send or receive data.
Note: Use the Activate or Deactivate method to control whether the class is active.
This property is not available at design time.
SysLog.LocalHost Property
The name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
getLocalHost(): string; setLocalHost(localHost: string): void;
Default Value
""
Remarks
The LocalHost property 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 class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the LocalHost property 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).
NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.
SysLog.LocalPort Property
The port in the local host where Syslog binds.
Syntax
getLocalPort(): number; setLocalPort(localPort: number): void;
Default Value
514
Remarks
The LocalPort property must be set before Syslog is activated (Active is set to True). It instructs the class to bind to a specific port (or communication endpoint) in the local machine.
Setting it to 0 (default) enables the TCP/IP stack to choose a port at random. The chosen port will be shown by the LocalPort property after the connection is established.
LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.
The LocalPort property is useful when trying to connect to services that require a trusted port in the client side.
SysLog.RemoteHost Property
Sets a specific host for outgoing log packets.
Syntax
getRemoteHost(): string; setRemoteHost(remoteHost: string): void;
Default Value
"255.255.255.255"
Remarks
When a call is made to the SendPacket method, the class will send it to whatever value is in RemoteHost. The default value is the broadcast address, "255.255.255.255".
SysLog.RemotePort Property
Sets a specific port for outgoing log packets.
Syntax
getRemotePort(): number; setRemotePort(remotePort: number): void;
Default Value
514
Remarks
When a call is made to the SendPacket method, the class will send to RemoteHost on RemotePort. The default value is 514, the standard port as defined in the BSD syslog RFC 3164.
SysLog.SSLAcceptServerCert Property
Instructs the class to unconditionally accept the server certificate that matches the supplied certificate.
Syntax
getSSLAcceptServerCert(): Certificate; setSSLAcceptServerCert(SSLAcceptServerCert: Certificate): void;
Default Value
Remarks
If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.
You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.
Please note that this functionality is provided only for cases where you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.
SysLog.SSLAuthenticateClients Property
If set to True, the server asks the client(s) for a certificate.
Syntax
isSSLAuthenticateClients(): boolean; setSSLAuthenticateClients(SSLAuthenticateClients: boolean): void;
Default Value
FALSE
Remarks
This property is used in conjunction with the SSLClientAuthentication event. Please refer to the documentation of the SSLClientAuthentication event for details.
SysLog.SSLCert Property
The certificate to be used during SSL negotiation.
Syntax
getSSLCert(): Certificate; setSSLCert(SSLCert: Certificate): void;
Default Value
Remarks
The digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the field to the encoded certificate. To select a certificate, use the store and subject fields.
SysLog.SSLEnabled Property
Whether TLS/SSL is enabled.
Syntax
isSSLEnabled(): boolean; setSSLEnabled(SSLEnabled: boolean): void;
Default Value
FALSE
Remarks
This setting specifies whether TLS/SSL is enabled in the class. When False (default) the class operates in plaintext mode. When True TLS/SSL is enabled.
Note: TLS/SSL can only be used when UseTCP is .
This property is not available at design time.
SysLog.SSLServerCert Property
The server certificate for the last established connection.
Syntax
getSSLServerCert(): Certificate;
Default Value
Remarks
SSLServerCert contains the server certificate for the last established connection.
SSLServerCert is reset every time a new connection is attempted.
This property is read-only.
SysLog.UseTCP Property
Whether to use TCP.
Syntax
isUseTCP(): boolean; setUseTCP(useTCP: boolean): void;
Default Value
FALSE
Remarks
This property specifies whether TCP is used. By default this proprety is False and UDP is used. When set to True TCP will be used as the underlying protocol.
When set to True the following additional settings are also applicable:
- SSLAuthenticateClients
- SSLEnabled
- SSLAcceptServerCert*
- SSLCert*
- SSLServerCert*
- TCPMessageDelimiter
SysLog.activate Method
Enables sending and receiving of data.
Syntax
async syslog.activate(): Promise<void>
Remarks
This method enables sending and receiving of data. When called the class will create a communication endpoint (socket) which can be used for sending and receiving UDP messages. This method must be called before using the class to send and receive data.
If the UseConnection configuration setting is set to , then a local association (connection) to the remote host is also created.
SysLog.config Method
Sets or retrieves a configuration setting.
Syntax
async syslog.config(configurationString : string): Promise<string>
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the 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 configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
SysLog.deactivate Method
Disables sending and receive of data.
Syntax
async syslog.deactivate(): Promise<void>
Remarks
This method disables sending and receiving of data. When called the class will destroy the existing socket and disable data communications.
SysLog.doEvents Method
Processes events from the internal message queue.
Syntax
async syslog.doEvents(): Promise<void>
Remarks
When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.
SysLog.reset Method
Reset the class.
Syntax
async syslog.reset(): Promise<void>
Remarks
This method will reset the class's properties to their default values.
SysLog.resolveRemoteHost Method
Resolves the hostname in RemoteHost to an IP address.
Syntax
async syslog.resolveRemoteHost(): Promise<void>
Remarks
This method resolves the hostname specified by RemoteHost to an IP address. The resolved value is available in the RemoteHost property after this method returns.
In most cases calling this method is not necessary, the class will resolve the hostname automatically when necessary. If DelayHostResolution is this method may be called to manually resolve RemoteHost if desired.
SysLog.sendPacket Method
Send a log packet to RemoteHost .
Syntax
async syslog.sendPacket(facility : number, severity : number, message : string): Promise<void>
Remarks
System log packets are composed of three main sections, each of which can be broken down into two smaller pieces.
The first section is the PRI, which contains the originating Facility and Severity of the Message. Facility is a value from 0 to 23, with each value being a different part of the system:
0 | Kernel messages |
1 | User-level messages |
2 | Mail system |
3 | System daemons |
4 | Security/authorization messages |
5 | Messages generated internally by syslogd |
6 | Line printer subsystem |

23 | Local use |
Severity is a value from 0 to 7 using the following convention:
0 | Emergency - the system is unusable |
1 | Alert - action must be taken immediately |
2 | Critical - critical conditions exist |
3 | Error - error conditions exist |
4 | Warning - warning conditions exist |
5 | Notice - normal but significant condition |
6 | Informational - informative message |
7 | Debug - debug-level messages |
The section sections contains a timestamp and hostname, both of which are automatically generated by the class. The third section is the Message itself.
SysLog.Connected Event
Fired immediately after a connection completes (or fails).
Syntax
syslog.on('Connected', listener: (e: {readonly remoteAddress: string, readonly remotePort: number, readonly statusCode: number, readonly description: string}) => void )
Remarks

Remarks
The ConnectionStatus event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.
The ConnectionEvent parameter indicates the type of connection event. Values may include the following:
Firewall connection complete. | |
Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable). | |
Remote host connection complete. | |
Remote host disconnected. | |
SSL or S/Shell connection broken. | |

RemotePort is the port on the remote host.
SysLog.Error Event
Information about errors during data delivery.
Syntax
syslog.on('Error', listener: (e: {readonly errorCode: number, readonly description: string}) => void )
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the class .
ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
SysLog.PacketIn Event
Fires whenever a system log packet is received.
Syntax

Remarks
System log packets are composed of three main sections, each of which can be broken down into two smaller pieces.
The first section is the PRI, which contains the originating FacilityCode and SeverityCode of the Message. FacilityCode is a value from 0 to 23, with each value being a different part of the system. Facility is a string representation of FacilityCode based on the following convention:
0 | Kernel messages |
1 | User-level messages |
2 | Mail system |
3 | System daemons |
4 | Security/authorization messages |
5 | Messages generated internally by syslogd |
6 | Line printer subsystem |

0 | Emergency - the system is unusable. |
1 | Alert - action must be taken immediately. |
2 | Critical - critical conditions exist. |
3 | Error - error conditions exist. |
4 | Warning - warning conditions exist. |
5 | Notice - normal but significant condition. |
6 | Informational - informative message. |
7 | Debug - debug-level messages. |
The second section contains the Timestamp and Hostname. Timestamp is a string that should conform to the standard structure "MMM DD, HH:MM:SS". The class will search for the Timestamp and verify that it conforms. If it conforms, the class will set Hostname, otherwise, everything after the PRI will be placed in Message.
If Conforms is TRUE, then the original syslog packet conforms to the syslog RFC and Timestamp, Hostname, and Message will all have valid values. Otherwise, you should parse the contents of Packet to verify the fields manually.
SourceAddress and SourcePort are the address and port from which Packet was sent. This can be an intermediate syslog server that is simply forwarding packets from the original host.
SysLog.SSLClientAuthentication Event
Fired when the client presents its credentials to the server.
Syntax
syslog.on('SSLClientAuthentication', listener: (e: {readonly remoteAddress: string, readonly remotePort: number, readonly certEncoded: string, readonly certEncodedB: Uint8Array, readonly certSubject: string, readonly certIssuer: string, readonly status: string, accept: boolean}) => void )
Remarks
This event fires when a client connects to the class and presents a certificate for authentication. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK").
RemoteAddress is the IP address of the connecting client.
RemotePort is the source port of the connecting client.
CertEncoded is the base64 encoded certificate presented by the client.
CertSubject is the subject of the certificate presented by the client.
CertIssuer is the subject of the issuer of the certificate presented by the client.
Status is the stauts of the certificate.
Accept defines whether the certificate is accepted.
SysLog.SSLServerAuthentication Event
Fires when connecting to the server.
Syntax
syslog.on('SSLServerAuthentication', listener: (e: {readonly remoteAddress: string, readonly remotePort: number, readonly certEncoded: string, readonly certEncodedB: Uint8Array, readonly certSubject: string, readonly certIssuer: string, readonly status: string, accept: boolean}) => void )
Remarks
This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
RemoteAddress is the IP address of the server.
RemotePort is the source port of the server.
CertEncoded is the base64 encoded certificate presented by the server.
CertSubject is the subject of the certificate presented by the server.
CertIssuer is the subject of the issuer of the certificate presented by the server.
Status is the stauts of the certificate.
Accept defines whether the certificate is accepted.
SysLog.SSLStatus Event
Shows the progress of the secure connection.
Syntax
syslog.on('SSLStatus', listener: (e: {readonly remoteAddress: string, readonly remotePort: number, readonly message: string}) => void )
Remarks
The event is fired for informational and logging purposes only. It is used to track the progress of the connection.
RemoteAddress is the IP address of the remote machine.
RemotePort is the port of the remote machine.
Message is the log message.

Constructors
public Certificate();
Creates a Certificate instance whose properties can be set. This is useful for use with CERTMGR when generating new certificates.
public Certificate(String certificateFile);
Opens CertificateFile and reads out the contents as an X509 public key.
public Certificate(byte[] certificateData);
Parses CertificateData as an X509 public key.
public Certificate(int certStoreType, String store, String storePassword, String subject);
CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).
public Certificate(int certStoreType, String store, String storePassword, String subject, String configurationString);
CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. ConfigurationString is a newline separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CyrptoAPI option. The default value is True (the key is persisted). "Thumbprint" - a MD5, SHA1, or SHA256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to cstUser, cstMachine, cstPublicKeyFile, and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).
public Certificate(int certStoreType, String store, String storePassword, byte[] encoded);
CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will load Encoded as an X509 certificate and search the opened store for a corresponding private key.
public Certificate(int certStoreType, byte[] storeBlob, String storePassword, String subject);
CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. StoreBlob is a string (binary- or base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the class will attempt to find the certificate identified by Subject .

LocalHost:
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 class initiate connections (or accept in the case of server classs) only through that interface. If the class 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). |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
LocalPort:
The port in the local host where the class binds.
This must be set before a connection is
attempted. It instructs the class 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. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
MaxPacketSize: The maximum length of the packets that can be received.This setting specifies the maximum size of the datagrams that the class will accept without truncation. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
QOSDSCPValue:
Used to specify an arbitrary QOS/DSCP setting (optional).UseConnection must be True to use this setting. This option allows you to specify an arbitrary DSCP value
between 0 and 63. The default is 0. When set to the default value the component will not set a DSCP value.
Note: This setting uses the qWAVE API is only available on Windows 7, Windows Server 2008 R2, and later. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
QOSTrafficType:
Used to specify QOS/DSCP settings (optional).UseConnection must be True to use this setting.
You may specify either the text or integer values: BestEffort (0), Background (1), ExcellentEffort (2), AudioVideo (3), Voice (4), and Control (5).
Note: This setting uses the qWAVE API which is only available on Windows Vista and Windows Server 2008 or above. Note: QOSTrafficType must be set before setting Active to true. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ShareLocalPort:
If set to True, allows more than one instance of the class to be active on the same local port.This option must be set before the class is activated through
the Active property or it will have no effect.
The default value for this setting is False. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
UseConnection:
Determines whether to use a connected socket.UseConnection specifies whether the class
should use a connected socket or not. The connection is
defined as an association in between the local address/port
and the remote address/port. As such, this
is not a connection in the traditional TCP sense. What it
means is only that the class will send and receive data
only to and from the specified destination.
The default value for this setting is False. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
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. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

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