# SysLog Component The Syslog class is used to send and receive network system log packets. ## Syntax ```text ipworks.SysLog ``` ## Remarks The Syslog struct implements a lightweight BSD syslog client as specified in RFC 3164 (User Datagram Protocol [UDP]), RFC 5425 (Secure Sockets Layer/Transport Layer Security [SSL/TLS]), and RFC 6587 (Transmission Control Protocol [TCP]). The struct is used to send and receive BSD system network logging packets. The first step in using the Syslog struct is to set [LocalHost](#localhost-property-syslog-component) and [LocalPort](#localport-property-syslog-component) to the interface and port on which the host will be receiving syslog packets, and then call the [Activate](#activate-method-syslog-component) method. For each packet, the struct will parse the headers and message and fire a [PacketIn](#packetin-event-syslog-component) event. ## Property List *The following is the full list of the properties of the component with short descriptions.

Use the [Activate](#activate-method-syslog-component) and [Deactivate](#deactivate-method-syslog-component) methods to control whether the struct is active. This property is read-only. ## Data Type **bool** # LocalHost Property ([SysLog](#syslog-component) Component) The name of the local host or user-assigned IP interface through which connections are initiated or accepted. ## Syntax *Go Syntax* ```text func (obj *SysLog) LocalHost() (string, error)func (obj *SysLog) SetLocalHost(value string) error ``` ## Default Value "" ## Remarks This 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 multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the struct initiate connections (or accept in the case of server structs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used. If the struct 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 multihomed 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. ## Data Type **string** # LocalPort Property ([SysLog](#syslog-component) Component) This property indicates the port in the local host where Syslog binds. ## Syntax *Go Syntax* ```text func (obj *SysLog) LocalPort() (int32, error)func (obj *SysLog) SetLocalPort(value int32) error ``` ## Default Value 514 ## Remarks The LocalPort property must be set before Syslog is activated. It instructs the struct to bind to a specific port (or communication endpoint) in the local machine. Setting it to *0* enables the Transmission Control Protocol (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 struct is [Active](#active-property-syslog-component). Any attempt to set the LocalPort property when the struct is [Active](#active-property-syslog-component) will generate an error. The LocalPort property is useful when trying to connect to services that require a trusted port in the client side. ## Data Type **int32** # RemoteHost Property ([SysLog](#syslog-component) Component) This property sets a specific host for outgoing log packets. ## Syntax *Go Syntax* ```text func (obj *SysLog) RemoteHost() (string, error)func (obj *SysLog) SetRemoteHost(value string) error ``` ## Default Value "255.255.255.255" ## Remarks When a call is made to the [SendPacket](#sendpacket-method-syslog-component) method, the struct will send it to whatever value is in RemoteHost. The default value is the broadcast address, "255.255.255.255". ## Data Type **string** # RemotePort Property ([SysLog](#syslog-component) Component) This property sets a specific port for outgoing log packets. ## Syntax *Go Syntax* ```text func (obj *SysLog) RemotePort() (int32, error)func (obj *SysLog) SetRemotePort(value int32) error ``` ## Default Value 514 ## Remarks When a call is made to the [SendPacket](#sendpacket-method-syslog-component) method, the struct will send to [RemoteHost](#remotehost-property-syslog-component) on RemotePort. The default value is 514, the standard port as defined in the BSD syslog RFC 3164. ## Data Type **int32** # SSLAcceptServerCertEffectiveDate Property ([SysLog](#syslog-component) Component) The date on which this certificate becomes valid. ## Syntax *Go Syntax* ```text func (obj *SysLog) SSLAcceptServerCertEffectiveDate() (string, error) ``` ## Default Value "" ## Remarks The date on which this certificate becomes valid.

This property is read-only. ## Data Type **string** # SSLServerCertSubject Property ([SysLog](#syslog-component) Component) The subject of the certificate used for client authentication. ## Syntax *Go Syntax* ```text func (obj *SysLog) SSLServerCertSubject() (string, error) ``` ## Default Value "" ## Remarks The subject of the certificate used for client authentication. This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject. If a matching certificate is found, the property is set to the full subject of the matching certificate. If an exact match is not found, the store is searched for subjects containing the value of the property. If a match is still not found, the property is set to an empty string, and no certificate is selected. The special value "*" picks a random certificate in the certificate store. The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=example@email.com". Common fields and their meanings are as follows: | Field | Meaning | | --- | --- | | CN | Common Name. This is commonly a hostname like www.server.com. | | O | Organization | | OU | Organizational Unit | | L | Locality | | S | State | | C | Country | | E | Email Address | If a field value contains a comma, it must be quoted. This property is read-only. ## Data Type **string** # SSLServerCertEncoded Property ([SysLog](#syslog-component) Component) The certificate (PEM/Base64 encoded). ## Syntax *Go Syntax* ```text func (obj *SysLog) SSLServerCertEncoded() ([]byte, error) ``` ## Default Value "" ## Remarks The certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The [SSLServerCertStore](#sslservercertstore-property-syslog-component) and [SSLServerCertSubject](#sslservercertsubject-property-syslog-component) properties also may be used to specify a certificate. When [SSLServerCertEncoded](#sslservercertencoded-property-syslog-component) is set, a search is initiated in the current [SSLServerCertStore](#sslservercertstore-property-syslog-component) for the private key of the certificate. If the key is found, [SSLServerCertSubject](#sslservercertsubject-property-syslog-component) is updated to reflect the full subject of the selected certificate; otherwise, [SSLServerCertSubject](#sslservercertsubject-property-syslog-component) is set to an empty string. This property is read-only. ## Data Type **[]byte** # UseTCP Property ([SysLog](#syslog-component) Component) This property specifies whether Transmission Control Protocol (TCP) is used. ## Syntax *Go Syntax* ```text func (obj *SysLog) UseTCP() (bool, error)func (obj *SysLog) SetUseTCP(value bool) error ``` ## Default Value false ## Remarks This property specifies whether TCP is used. By default, this property 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](#sslauthenticateclients-property-syslog-component) - [SSLEnabled](#sslenabled-property-syslog-component) - SSLAcceptServerCert - SSLCert - SSLServerCert - [TCPMessageDelimiter](#TCPMessageDelimiter) ## Data Type **bool** # Activate Method ([SysLog](#syslog-component) Component) This method enables sending and receiving of data. ## Syntax *Go Syntax* ```text func (obj *SysLog) Activate() error ``` ## Remarks This method enables sending and receiving of data. When called, the struct will create a communication endpoint (socket) that can be used for sending and receiving User Datagram Protocol (UDP) messages. This method must be called before using the struct to send and receive data. If the [UseConnection](#UseConnection) configuration setting is set to *true*, then a local association (connection) to the remote host is also created. # Config Method ([SysLog](#syslog-component) Component) Sets or retrieves a configuration setting. ## Syntax *Go Syntax* ```text func (obj *SysLog) Config(ConfigurationString string) (string, error) ``` ## Remarks Config is a generic method available in every struct. It is used to set and retrieve [configuration settings](#config-settings-syslog-component) for the struct. These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the struct, 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](#config-settings-syslog-component), you must call *Config("PROPERTY")*. The value will be returned as a string. # Deactivate Method ([SysLog](#syslog-component) Component) This method disables sending and receive of data. ## Syntax *Go Syntax* ```text func (obj *SysLog) Deactivate() error ``` ## Remarks This method disables sending and receiving of data. When called, the struct will destroy the existing socket and disable data communications. # DoEvents Method ([SysLog](#syslog-component) Component) This method processes events from the internal message queue. ## Syntax *Go Syntax* ```text func (obj *SysLog) DoEvents() error ``` ## Remarks When DoEvents is called, the struct processes any available events. If no events are available, it waits for a preset period of time, and then returns. # Reset Method ([SysLog](#syslog-component) Component) This method will reset the class. ## Syntax *Go Syntax* ```text func (obj *SysLog) Reset() error ``` ## Remarks This method will reset the struct's properties to their default values. # ResolveRemoteHost Method ([SysLog](#syslog-component) Component) This method resolves the hostname in RemoteHost to an IP address. ## Syntax *Go Syntax* ```text func (obj *SysLog) ResolveRemoteHost() error ``` ## Remarks This method resolves the hostname specified by [RemoteHost](#remotehost-property-syslog-component) to an IP address. The resolved value is available in the [RemoteHost](#remotehost-property-syslog-component) property after this method returns. In most cases, calling this method is not necessary; the struct will resolve the hostname automatically when needed. If [DelayHostResolution](#DelayHostResolution) is *true*, this method may be called to manually resolve [RemoteHost](#remotehost-property-syslog-component), if desired. # SendPacket Method ([SysLog](#syslog-component) Component) This method sends a log packet to RemoteHost . ## Syntax *Go Syntax* ```text func (obj *SysLog) SendPacket(Facility int32, Severity int32, Message string) error ``` ## 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 | | 7 | Network news subsystem | | 8 | UUCP subsystem | | 9 | Clock daemon | | 10 | Security/authorization messages | | 11 | FTP daemon | | 12 | NTP subsystem | | 13 | Log audit | | 14 | Log alert | | 15 | Clock daemon | | 16 | Local use | | 17 | Local use | | 18 | Local use | | 19 | Local use | | 20 | Local use | | 21 | Local use | | 22 | Local use | | 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 second section contains a timestamp and hostname, both of which are automatically generated by the struct. The third section is the *Message*. # Connected Event ([SysLog](#syslog-component) Component) This event is fired immediately after a connection completes (or fails). ## Syntax *Go Syntax* ```text // SysLogConnectedEventArgs carries the SysLog Connected event's parameters. type SysLogConnectedEventArgs struct {...} func (args *SysLogConnectedEventArgs) RemoteAddress() string func (args *SysLogConnectedEventArgs) RemotePort() int32 func (args *SysLogConnectedEventArgs) StatusCode() int32 func (args *SysLogConnectedEventArgs) Description() string // SysLogConnectedEvent defines the signature of the SysLog Connected event's handler function. type SysLogConnectedEvent func(sender *SysLog, args *SysLogConnectedEventArgs) func (obj *SysLog) GetOnConnectedHandler() SysLogConnectedEvent func (obj *SysLog) SetOnConnectedHandler(handlerFunc SysLogConnectedEvent) ``` ## Remarks This event fires after a connection completes or fails. *StatusCode* is the value returned by the system Transmission Control Protocol (TCP)/IP stack. This will be *0* if the connection was successful. *Description* contains a human readable description of the status. This will be *OK* if the connection was successful. *RemoteAddress* is the IP address of the remote host. *RemotePort* is the port on the remote host. # ConnectionStatus Event ([SysLog](#syslog-component) Component) This event is fired to indicate changes in a connection state. ## Syntax *Go Syntax* ```text // SysLogConnectionStatusEventArgs carries the SysLog ConnectionStatus event's parameters. type SysLogConnectionStatusEventArgs struct {...} func (args *SysLogConnectionStatusEventArgs) ConnectionEvent() string func (args *SysLogConnectionStatusEventArgs) StatusCode() int32 func (args *SysLogConnectionStatusEventArgs) Description() string // SysLogConnectionStatusEvent defines the signature of the SysLog ConnectionStatus event's handler function. type SysLogConnectionStatusEvent func(sender *SysLog, args *SysLogConnectionStatusEventArgs) func (obj *SysLog) GetOnConnectionStatusHandler() SysLogConnectionStatusEvent func (obj *SysLog) SetOnConnectionStatusHandler(handlerFunc SysLogConnectionStatusEvent) ``` ## Remarks The ConnectionStatus event is fired when the connection state changes: for example, upon 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. | | | Firewall host disconnected. | *StatusCode* has the error code returned by the Transmission Control Protocol (TCP)/IP stack. *Description* contains a description of this code. The value of *StatusCode* is equal to the value of the error. # Disconnected Event ([SysLog](#syslog-component) Component) This event is fired when a connection is closed. ## Syntax *Go Syntax* ```text // SysLogDisconnectedEventArgs carries the SysLog Disconnected event's parameters. type SysLogDisconnectedEventArgs struct {...} func (args *SysLogDisconnectedEventArgs) RemoteAddress() string func (args *SysLogDisconnectedEventArgs) RemotePort() int32 func (args *SysLogDisconnectedEventArgs) StatusCode() int32 func (args *SysLogDisconnectedEventArgs) Description() string // SysLogDisconnectedEvent defines the signature of the SysLog Disconnected event's handler function. type SysLogDisconnectedEvent func(sender *SysLog, args *SysLogDisconnectedEventArgs) func (obj *SysLog) GetOnDisconnectedHandler() SysLogDisconnectedEvent func (obj *SysLog) SetOnDisconnectedHandler(handlerFunc SysLogDisconnectedEvent) ``` ## Remarks This event fires when a connection is closed. *StatusCode* is the value returned by the system Transmission Control Protocol (TCP)/IP stack. This will be *0* if the connection was successful. *Description* contains a human readable description of the status. This will be *OK* if the connection was successful. *RemoteAddress* is the IP address of the remote host. *RemotePort* is the port on the remote host. # Error Event ([SysLog](#syslog-component) Component) Fired when information is available about errors during data delivery. ## Syntax *Go Syntax* ```text // SysLogErrorEventArgs carries the SysLog Error event's parameters. type SysLogErrorEventArgs struct {...} func (args *SysLogErrorEventArgs) ErrorCode() int32 func (args *SysLogErrorEventArgs) Description() string // SysLogErrorEvent defines the signature of the SysLog Error event's handler function. type SysLogErrorEvent func(sender *SysLog, args *SysLogErrorEventArgs) func (obj *SysLog) GetOnErrorHandler() SysLogErrorEvent func (obj *SysLog) SetOnErrorHandler(handlerFunc SysLogErrorEvent) ``` ## Remarks The Error event is fired in case of exceptional conditions during message processing. Normally the struct fails with an error. The *ErrorCode* parameter contains an error code, and the *Description* parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the [Error Codes](#trappable-errors-syslog-component) section. # PacketIn Event ([SysLog](#syslog-component) Component) This event fires whenever a system log packet is received. ## Syntax *Go Syntax* ```text // SysLogPacketInEventArgs carries the SysLog PacketIn event's parameters. type SysLogPacketInEventArgs struct {...} func (args *SysLogPacketInEventArgs) FacilityCode() int32 func (args *SysLogPacketInEventArgs) Facility() string func (args *SysLogPacketInEventArgs) SeverityCode() int32 func (args *SysLogPacketInEventArgs) Severity() string func (args *SysLogPacketInEventArgs) Timestamp() string func (args *SysLogPacketInEventArgs) Hostname() string func (args *SysLogPacketInEventArgs) Message() string func (args *SysLogPacketInEventArgs) Conforms() bool func (args *SysLogPacketInEventArgs) Packet() []byte func (args *SysLogPacketInEventArgs) SourceAddress() string func (args *SysLogPacketInEventArgs) SourcePort() int32 // SysLogPacketInEvent defines the signature of the SysLog PacketIn event's handler function. type SysLogPacketInEvent func(sender *SysLog, args *SysLogPacketInEventArgs) func (obj *SysLog) GetOnPacketInHandler() SysLogPacketInEvent func (obj *SysLog) SetOnPacketInHandler(handlerFunc SysLogPacketInEvent) ``` ## 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 | | 7 | Network news subsystem | | 8 | UUCP subsystem | | 9 | Clock daemon | | 10 | Security/authorization messages | | 11 | FTP daemon | | 12 | NTP subsystem | | 13 | Log audit | | 14 | Log alert | | 15 | Clock daemon | | 16 | Local use | | 17 | Local use | | 18 | Local use | | 19 | Local use | | 20 | Local use | | 21 | Local use | | 22 | Local use | | 23 | Local use | *SeverityCode* is a value from 0 to 7. *Severity* is a string representation of *SeverityCode* 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 second section contains the *Timestamp* and *Hostname*. Timestamp is a string that should conform to the standard structure "MMM DD, HH:MM:SS". The struct will search for the *Timestamp* and verify that it conforms. If it conforms, the struct 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. # SSLClientAuthentication Event ([SysLog](#syslog-component) Component) This is event fired when the client presents its credentials to the server. ## Syntax *Go Syntax* ```text // SysLogSSLClientAuthenticationEventArgs carries the SysLog SSLClientAuthentication event's parameters. type SysLogSSLClientAuthenticationEventArgs struct {...} func (args *SysLogSSLClientAuthenticationEventArgs) RemoteAddress() string func (args *SysLogSSLClientAuthenticationEventArgs) RemotePort() int32 func (args *SysLogSSLClientAuthenticationEventArgs) CertEncoded() []byte func (args *SysLogSSLClientAuthenticationEventArgs) CertSubject() string func (args *SysLogSSLClientAuthenticationEventArgs) CertIssuer() string func (args *SysLogSSLClientAuthenticationEventArgs) Status() string func (args *SysLogSSLClientAuthenticationEventArgs) Accept() bool func (args *SysLogSSLClientAuthenticationEventArgs) SetAccept(value bool) // SysLogSSLClientAuthenticationEvent defines the signature of the SysLog SSLClientAuthentication event's handler function. type SysLogSSLClientAuthenticationEvent func(sender *SysLog, args *SysLogSSLClientAuthenticationEventArgs) func (obj *SysLog) GetOnSSLClientAuthenticationHandler() SysLogSSLClientAuthenticationEvent func (obj *SysLog) SetOnSSLClientAuthenticationHandler(handlerFunc SysLogSSLClientAuthenticationEvent) ``` ## Remarks This event fires when a client connects to the struct 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 or not to continue. 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 status of the certificate. *Accept* defines whether the certificate is accepted. # SSLServerAuthentication Event ([SysLog](#syslog-component) Component) This event fires when connecting to the server. ## Syntax *Go Syntax* ```text // SysLogSSLServerAuthenticationEventArgs carries the SysLog SSLServerAuthentication event's parameters. type SysLogSSLServerAuthenticationEventArgs struct {...} func (args *SysLogSSLServerAuthenticationEventArgs) RemoteAddress() string func (args *SysLogSSLServerAuthenticationEventArgs) RemotePort() int32 func (args *SysLogSSLServerAuthenticationEventArgs) CertEncoded() []byte func (args *SysLogSSLServerAuthenticationEventArgs) CertSubject() string func (args *SysLogSSLServerAuthenticationEventArgs) CertIssuer() string func (args *SysLogSSLServerAuthenticationEventArgs) Status() string func (args *SysLogSSLServerAuthenticationEventArgs) Accept() bool func (args *SysLogSSLServerAuthenticationEventArgs) SetAccept(value bool) // SysLogSSLServerAuthenticationEvent defines the signature of the SysLog SSLServerAuthentication event's handler function. type SysLogSSLServerAuthenticationEvent func(sender *SysLog, args *SysLogSSLServerAuthenticationEventArgs) func (obj *SysLog) GetOnSSLServerAuthenticationHandler() SysLogSSLServerAuthenticationEvent func (obj *SysLog) SetOnSSLServerAuthenticationHandler(handlerFunc SysLogSSLServerAuthenticationEvent) ``` ## Remarks During this event, the client can decide whether or not to continue with the connection process. 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 or not to continue. 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 status of the certificate. *Accept* defines whether the certificate is accepted. # SSLStatus Event ([SysLog](#syslog-component) Component) This event shows the progress of the secure connection. ## Syntax *Go Syntax* ```text // SysLogSSLStatusEventArgs carries the SysLog SSLStatus event's parameters. type SysLogSSLStatusEventArgs struct {...} func (args *SysLogSSLStatusEventArgs) RemoteAddress() string func (args *SysLogSSLStatusEventArgs) RemotePort() int32 func (args *SysLogSSLStatusEventArgs) Message() string // SysLogSSLStatusEvent defines the signature of the SysLog SSLStatus event's handler function. type SysLogSSLStatusEvent func(sender *SysLog, args *SysLogSSLStatusEventArgs) func (obj *SysLog) GetOnSSLStatusHandler() SysLogSSLStatusEvent func (obj *SysLog) SetOnSSLStatusHandler(handlerFunc SysLogSSLStatusEvent) ``` ## 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. # Config Settings ([SysLog](#syslog-component) Component) The struct 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 struct, access to these *internal properties* is provided through the [Config](#config-method-syslog-component) method. ### Syslog Config Settings **AcceptData**: Whether the component can accept/receive data.When set to False, the struct will no longer be able to accept any data.

Append the index in square brackets to refer to the SD-Param field in the specified index: *SDParamValue[index]* NOTE: This configuration setting is applicable only when [Version](#Version) is set to *1* (RFC 5424) The following example demonstrates how to set the Struct-Data configs: ```csharp syslog.Config("SDElementCount=2"); syslog.Config("SDElementIndex=0"); syslog.Config("SDElementID=examplePriority@32473"); syslog.Config("SDParamCount=1"); syslog.Config("SDParamName[0]=class"); syslog.Config("SDParamValue[0]=high"); syslog.Config("SDElementIndex=1"); syslog.Config("SDElementID=exampleSDID@32473"); syslog.Config("SDParamCount=2"); syslog.Config("SDParamName[0]=iut"); syslog.Config("SDParamValue[0]=3"); syslog.Config("SDParamName[1]=eventSource"); syslog.Config("SDParamValue[1]=Application"); ``` **TCPMessageDelimiter**: The message delimiter to use (if any) when sending and receiving over TCP.When [UseTCP](#usetcp-property-syslog-component) is set to True, messages may be sent and received using either Octet Counting or Non-Transparent-Framing schemes to separate messages sent over the wire. This setting defines the delimiter to use in the Non-Transparent-Framing scheme when sending messages. Possible values are as follows: | | | | --- | --- | | 0 (None - Default) | Octet Counting is used, there is no delimiter character | | 1 (Cr) | The carriage return character is used as a message delimiter | | 2 (Lf) | The line feed character is used as a message delimiter | | 3 (CrLf) | The two character carriage return line feed sequence is used as a message delimiter | | 4 (Null) | A single null byte is used as a message delimiter | This configuration setting is applicable only when sending a message and [UseTCP](#usetcp-property-syslog-component) is set to True. **UseHostname**: Determines if the local host name or IP address is used in the Syslog header. If set to False, the struct will use the IP address of the local host name in the header of the Syslog packet. The default value is True. **UseLocalTime**: Indicates whether to use local time or GMT time for packet timestamps.Setting this to True will generate timestamps based on the time in your locality, taking into account your time zone. When this option is False (default), GMT timestamps are generated. **Version**: Determines which Syslog version to use. | | | | --- | --- | | 0 (RFC 3164 - Default) | Uses RFC 3164 | | 1 (RFC 5424) | Uses RFC 5424 | This configuration setting specifies which version of Syslog will be used.

NOTE: This configuration setting is available only in Windows. **DelayHostResolution**: Whether the hostname is resolved when RemoteHost is set.This configuration setting specifies whether a hostname is resolved immediately when [RemoteHost](#remotehost-property-syslog-component) is set. If *true* the struct will resolve the hostname and the IP address will be present in the [RemoteHost](#remotehost-property-syslog-component) property. If *false*, the hostname is not resolved until needed by the component when a method to connect or send data is called. If desired, [ResolveRemoteHost](#resolveremotehost-method-syslog-component) may be called to manually resolve the value in [RemoteHost](#remotehost-property-syslog-component) at any time. The default value is *false*. **DestinationAddress**: Used to get the destination address from the packet information.If [CaptureIPPacketInfo](#CaptureIPPacketInfo) is set to True, then this will be populated with the packet's destination address when a packet is received. This information will be accessible in the DataIn event. NOTE: This configuration setting is available only in Windows. **DontFragment**: Used to set the Don't Fragment flag of outgoing packets.When set to True, packets sent by the struct will have the Don't Fragment flag set. The default value is False. **LocalHost**: The name of the local host through which connections are initiated or accepted. The [LocalHost](#localhost-property-syslog-component) 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 multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the struct initiate connections (or accept in the case of server structs) only through that interface. If the struct is connected, the [LocalHost](#localhost-property-syslog-component) 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 multihomed hosts (machines with more than one IP interface). **LocalPort**: The port in the local host where the struct binds. This configuration setting must be set before a connection is attempted. It instructs the struct 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](#localport-property-syslog-component) after the connection is established. [LocalPort](#localport-property-syslog-component) cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error. This configuration setting is useful when trying to connect to services that require a trusted port on 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 configuration setting specifies the maximum size of the datagrams that the struct will accept without truncation. **QOSDSCPValue**: Used to specify an arbitrary QOS/DSCP setting (optional).[UseConnection](#UseConnection) must be True to use this configuration 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 configuration setting uses the qWAVE API and is available only on Windows 7, Windows Server 2008 R2, and later. **QOSTrafficType**: Used to specify QOS/DSCP settings (optional).[UseConnection](#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 configuration setting uses the qWAVE API and is available only on Windows Vista and Windows Server 2008 or above. NOTE: QOSTrafficType must be set before setting [Active](#active-property-syslog-component) to True. **ShareLocalPort**: If set to True, allows more than one instance of the struct to be active on the same local port.This option must be set before the struct is activated through the [Active](#active-property-syslog-component) property or it will have no effect. The default value for this setting is False. **UseConnection**: Determines whether to use a connected socket.[UseConnection](#UseConnection) specifies whether or not the struct should use a connected socket. 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 Transmission Control Protocol (TCP) sense. It means only that the struct will send and receive data 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 it will create an IPv4 socket. To use IPv6 instead, set this to True. ### Socket Config Settings **AbsoluteTimeout**: Determines whether timeouts are inactivity timeouts or absolute timeouts.If [AbsoluteTimeout](#AbsoluteTimeout) is set to True, any method that 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 User Datagram Protocol (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 Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the *InBufferSize* setting can provide significant improvements in performance. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the struct 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. In some cases, increasing the value of the *OutBufferSize* setting can provide significant improvements in performance. Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the struct is activated the *OutBufferSize* reverts to its defined size. The same happens if you attempt to make it too large or too small. ### Base Config Settings **BuildInfo**: Information about the product's build.When queried, this setting will return a string containing information about the product's build. **CodePage**: The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).

It will return the following information: - Product: The product the license is for. - Product Key: The key the license was generated from. - License Source: Where the license was found (e.g., RuntimeLicense, License File). - License Type: The type of license installed (e.g., Royalty Free, Single Server). - Last Valid Build: The last valid build number for which the license will work. **MaskSensitiveData**: Whether sensitive data is masked in log messages.In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to *true* to mask sensitive data. The default is *true*. **UseInternalSecurityAPI**: Whether or not to use the system security libraries or an internal implementation. When set to *false*, the struct will use the system security libraries by default to perform cryptographic functions where applicable. Setting this configuration setting to *true* tells the struct to use the internal implementation instead of using the system security libraries. On Windows, this setting is set to *false* by default. On Linux/macOS, this setting is set to *true* by default. To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the [OpenSSL Notes](platforms.md) section. # Trappable Errors ([SysLog](#syslog-component) Component) ### SysLog Errors | | | | --- | --- | | 451 | Unable to acquire valid system time. | ### UDP Errors | | | | --- | --- | | 104 | UDP is already [Active](#active-property-syslog-component). | | 106 | You cannot change the [LocalPort](#localport-property-syslog-component) while the struct is [Active](#active-property-syslog-component). | | 107 | You cannot change the [LocalHost](#localhost-property-syslog-component) at this time.
