Struct ipworks::SysLog

Properties   Methods   Events   Config Settings   Errors  

The Syslog struct is used to send and receive network system log packets.

Syntax

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 local_host and local_port to the interface and port on which the host will be receiving syslog packets, and then call the activate method. For each packet, the struct will parse the headers and message and fire a on_packet_in event.

Object Lifetime

The new() method returns a mutable reference to a struct instance. The object itself is kept in the global list maintained by IPWorks. Due to this, the SysLog struct cannot be disposed of automatically. Please, call the dispose(&mut self) method of SysLog when you have finished using the instance.

The following is a list of config settings for the struct with short descriptions. Click on the links for further details.

active property (SysLog Struct)

This property indicates whether the struct is active.

Syntax

fn active(&self ) -> Result<bool, IPWorksError> 

Default Value

false

Remarks

This property indicates whether the struct is currently active and can send or receive data. Use the activate and deactivate methods to control whether the struct is active.

This property is read-only.

Data Type

bool

local_host property (SysLog Struct)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

fn local_host(&self ) -> Result<String, IPWorksError> 
fn set_local_host(&self, value : &str) ->  Option<IPWorksError> 
fn set_local_host_ref(&self, value : &String) ->  Option<IPWorksError> 

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 local_host 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: local_host is not persistent. You must always set it in code, and never in the property window.

Data Type

String

local_port property (SysLog Struct)

This property indicates the port in the local host where Syslog binds.

Syntax

fn local_port(&self ) -> Result<i32, IPWorksError> 
fn set_local_port(&self, value : i32) ->  Option<IPWorksError> 

Default Value

514

Remarks

The local_port 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 local_port property after the connection is established.

local_port cannot be changed once the struct is active. Any attempt to set the local_port property when the struct is active will generate an error.

The local_port property is useful when trying to connect to services that require a trusted port in the client side.

Data Type

i32

remote_host property (SysLog Struct)

This property sets a specific host for outgoing log packets.

Syntax

fn remote_host(&self ) -> Result<String, IPWorksError>

fn set_remote_host_ref(&self, value : &String) ->  Option<IPWorksError> 

Default Value

"255.255.255.255"

Remarks

When a call is made to the send_packet method, the struct will send it to whatever value is in remote_host. The default value is the broadcast address, "255.255.255.255".

Data Type

String

remote_port property (SysLog Struct)

This property sets a specific port for outgoing log packets.

Syntax

fn remote_port(&self ) -> Result<i32, IPWorksError> 
fn set_remote_port(&self, value : i32) ->  Option<IPWorksError> 

Default Value

514

Remarks

When a call is made to the send_packet method, the struct will send to remote_host on remote_port. The default value is 514, the standard port as defined in the BSD syslog RFC 3164.

fn reset(&self) -> Result<(), IPWorksError>

Remarks

This method will reset the struct's properties to their default values.

resolve_remote_host method (SysLog Struct)

This method resolves the hostname in RemoteHost to an IP address.

Syntax

fn resolve_remote_host(&self) -> Result<(), IPWorksError>

Remarks

This method resolves the hostname specified by remote_host to an IP address. The resolved value is available in the remote_host 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 is true, this method may be called to manually resolve remote_host, if desired.

send_packet method (SysLog Struct)

This method sends a log packet to RemoteHost .

Syntax

fn send_packet(&self, facility : i32, severity : i32, message : &str) -> Result<(), IPWorksError>

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:

severity is a value from 0 to 7 using the following convention:

The second section contains a timestamp and hostname, both of which are automatically generated by the struct. The third section is the message.

on_connected event (SysLog Struct)

This event is fired immediately after a connection completes (or fails).

Syntax

// SysLogConnectedEventArgs carries the SysLog Connected event's parameters.
pub struct SysLogConnectedEventArgs {
  fn remote_address(&self) -> &String
  fn remote_port(&self) -> i32
  fn status_code(&self) -> i32
  fn description(&self) -> &String
}

// SysLogConnectedEvent defines the signature of the SysLog Connected event's handler function.
pub trait SysLogConnectedEvent {
  fn on_connected(&self, sender : SysLog, e : &mut SysLogConnectedEventArgs);
}

impl <'a> SysLog<'a> {
  pub fn on_connected(&self) -> &'a dyn SysLogConnectedEvent;
  pub fn set_on_connected(&mut self, value : &'a dyn SysLogConnectedEvent);
  ...
}

Remarks

This event fires after a connection completes or fails.

status_code 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.

remote_address is the IP address of the remote host.

remote_port is the port on the remote host.

on_connection_status event (SysLog Struct)

This event is fired to indicate changes in a connection state.

Syntax

// SysLogConnectionStatusEventArgs carries the SysLog ConnectionStatus event's parameters.
pub struct SysLogConnectionStatusEventArgs {
  fn connection_event(&self) -> &String
  fn status_code(&self) -> i32
  fn description(&self) -> &String
}

// SysLogConnectionStatusEvent defines the signature of the SysLog ConnectionStatus event's handler function.
pub trait SysLogConnectionStatusEvent {
  fn on_connection_status(&self, sender : SysLog, e : &mut SysLogConnectionStatusEventArgs);
}

impl <'a> SysLog<'a> {
  pub fn on_connection_status(&self) -> &'a dyn SysLogConnectionStatusEvent;
  pub fn set_on_connection_status(&mut self, value : &'a dyn SysLogConnectionStatusEvent);
  ...
}

Remarks

The on_connection_status 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 connection_event parameter indicates the type of connection event. Values may include the following:

status_code has the error code returned by the Transmission Control Protocol (TCP)/IP stack. description contains a description of this code. The value of status_code is equal to the value of the error.

on_disconnected event (SysLog Struct)

This event is fired when a connection is closed.

Syntax

// SysLogDisconnectedEventArgs carries the SysLog Disconnected event's parameters.
pub struct SysLogDisconnectedEventArgs {
  fn remote_address(&self) -> &String
  fn remote_port(&self) -> i32
  fn status_code(&self) -> i32
  fn description(&self) -> &String
}

// SysLogDisconnectedEvent defines the signature of the SysLog Disconnected event's handler function.
pub trait SysLogDisconnectedEvent {
  fn on_disconnected(&self, sender : SysLog, e : &mut SysLogDisconnectedEventArgs);
}

impl <'a> SysLog<'a> {
  pub fn on_disconnected(&self) -> &'a dyn SysLogDisconnectedEvent;
  pub fn set_on_disconnected(&mut self, value : &'a dyn SysLogDisconnectedEvent);
  ...
}

Remarks

This event fires when a connection is closed.

status_code 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.

remote_address is the IP address of the remote host.

remote_port is the port on the remote host.

on_error event (SysLog Struct)

Fired when information is available about errors during data delivery.

Syntax

// SysLogErrorEventArgs carries the SysLog Error event's parameters.
pub struct SysLogErrorEventArgs {
  fn error_code(&self) -> i32
  fn description(&self) -> &String
}

// SysLogErrorEvent defines the signature of the SysLog Error event's handler function.
pub trait SysLogErrorEvent {
  fn on_error(&self, sender : SysLog, e : &mut SysLogErrorEventArgs);
}

impl <'a> SysLog<'a> {
  pub fn on_error(&self) -> &'a dyn SysLogErrorEvent;
  pub fn set_on_error(&mut self, value : &'a dyn SysLogErrorEvent);
  ...
}

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the struct fails with an error.

The error_code 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 section.

on_packet_in event (SysLog Struct)

This event fires whenever a system log packet is received.

Syntax

// SysLogPacketInEventArgs carries the SysLog PacketIn event's parameters.
pub struct SysLogPacketInEventArgs {
  fn facility_code(&self) -> i32
  fn facility(&self) -> &String
  fn severity_code(&self) -> i32
  fn severity(&self) -> &String
  fn timestamp(&self) -> &String
  fn hostname(&self) -> &String
  fn message(&self) -> &String
  fn conforms(&self) -> bool
  fn packet(&self) -> &[u8]
  fn source_address(&self) -> &String
  fn source_port(&self) -> i32
}

// SysLogPacketInEvent defines the signature of the SysLog PacketIn event's handler function.
pub trait SysLogPacketInEvent {
  fn on_packet_in(&self, sender : SysLog, e : &mut SysLogPacketInEventArgs);
}

impl <'a> SysLog<'a> {
  pub fn on_packet_in(&self) -> &'a dyn SysLogPacketInEvent;
  pub fn set_on_packet_in(&mut self, value : &'a dyn 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 facility_code and severity_code of the message. facility_code is a value from 0 to 23, with each value being a different part of the system. facility is a string representation of facility_code based on the following convention:

severity_code is a value from 0 to 7. severity is a string representation of severity_code using the following convention:

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.

source_address and source_port 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.

on_ssl_client_authentication event (SysLog Struct)

This is event fired when the client presents its credentials to the server.

Syntax

// SysLogSSLClientAuthenticationEventArgs carries the SysLog SSLClientAuthentication event's parameters.
pub struct SysLogSSLClientAuthenticationEventArgs {
  fn remote_address(&self) -> &String
  fn remote_port(&self) -> i32
  fn cert_encoded(&self) -> &[u8]
  fn cert_subject(&self) -> &String
  fn cert_issuer(&self) -> &String
  fn status(&self) -> &String
  fn accept(&self) -> bool
  fn set_accept(&self, value : bool)
}

// SysLogSSLClientAuthenticationEvent defines the signature of the SysLog SSLClientAuthentication event's handler function.
pub trait SysLogSSLClientAuthenticationEvent {
  fn on_ssl_client_authentication(&self, sender : SysLog, e : &mut SysLogSSLClientAuthenticationEventArgs);
}

impl <'a> SysLog<'a> {
  pub fn on_ssl_client_authentication(&self) -> &'a dyn SysLogSSLClientAuthenticationEvent;
  pub fn set_on_ssl_client_authentication(&mut self, value : &'a dyn 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").

remote_address is the IP address of the connecting client.

remote_port is the source port of the connecting client.

cert_encoded is the base64-encoded certificate presented by the client.

cert_subject is the subject of the certificate presented by the client.

cert_issuer 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.

on_ssl_server_authentication event (SysLog Struct)

This event fires when connecting to the server.

Syntax

// SysLogSSLServerAuthenticationEventArgs carries the SysLog SSLServerAuthentication event's parameters.
pub struct SysLogSSLServerAuthenticationEventArgs {
  fn remote_address(&self) -> &String
  fn remote_port(&self) -> i32
  fn cert_encoded(&self) -> &[u8]
  fn cert_subject(&self) -> &String
  fn cert_issuer(&self) -> &String
  fn status(&self) -> &String
  fn accept(&self) -> bool
  fn set_accept(&self, value : bool)
}

// SysLogSSLServerAuthenticationEvent defines the signature of the SysLog SSLServerAuthentication event's handler function.
pub trait SysLogSSLServerAuthenticationEvent {
  fn on_ssl_server_authentication(&self, sender : SysLog, e : &mut SysLogSSLServerAuthenticationEventArgs);
}

impl <'a> SysLog<'a> {
  pub fn on_ssl_server_authentication(&self) -> &'a dyn SysLogSSLServerAuthenticationEvent;
  pub fn set_on_ssl_server_authentication(&mut self, value : &'a dyn 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.

remote_address is the IP address of the server.

remote_port is the source port of the server.

cert_encoded is the base64-encoded certificate presented by the server.

cert_subject is the subject of the certificate presented by the server.

cert_issuer 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.

on_ssl_status event (SysLog Struct)

This event shows the progress of the secure connection.

Syntax

// SysLogSSLStatusEventArgs carries the SysLog SSLStatus event's parameters.
pub struct SysLogSSLStatusEventArgs {
  fn remote_address(&self) -> &String
  fn remote_port(&self) -> i32
  fn message(&self) -> &String
}

// SysLogSSLStatusEvent defines the signature of the SysLog SSLStatus event's handler function.
pub trait SysLogSSLStatusEvent {
  fn on_ssl_status(&self, sender : SysLog, e : &mut SysLogSSLStatusEventArgs);
}

impl <'a> SysLog<'a> {
  pub fn on_ssl_status(&self) -> &'a dyn SysLogSSLStatusEvent;
  pub fn set_on_ssl_status(&mut self, value : &'a dyn SysLogSSLStatusEvent);
  ...
}

Remarks

The event is fired for informational and logging purposes only. It is used to track the progress of the connection.

remote_address is the IP address of the remote machine.

remote_port is the port of the remote machine.

message is the log message.

Config Settings (SysLog Struct)

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 method.

Syslog Config Settings

UDP Config Settings

Socket Config Settings

Base Config Settings

Trappable Errors (SysLog Struct)

SysLog Errors

UDP Errors

SSL Errors

TCP/IP Errors
