SysLog Class

Properties   Methods   Events   Config Settings   Errors  

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

Syntax

class ipworks.SysLog

Remarks

The Syslog class 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 class is used to send and receive BSD system network logging packets.

The first step in using the Syslog class is to set local_host and local_port to the interface and port on which the host will be receiving syslog packets, and then set active to True. For each packet, the class will parse the headers and message and fire a on_packet_in event.

active Property

This property indicates whether the class is active.

Syntax

def get_active() -> bool: ...

active = property(get_active, None)

Default Value

FALSE

Remarks

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

This property is read-only.

local_host Property

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

Syntax

def get_local_host() -> str: ...
def set_local_host(value: str) -> None: ...

local_host = property(get_local_host, set_local_host)

Default Value

""

Remarks

The local_host 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 class initiate connections (or accept in the case of server classs) 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 class 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.

local_port Property

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

Syntax

def get_local_port() -> int: ...
def set_local_port(value: int) -> None: ...

local_port = property(get_local_port, set_local_port)

Default Value

514

Remarks

The local_port 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 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 class is active. Any attempt to set the local_port property when the class 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.

remote_host Property

This property sets a specific host for outgoing log packets.

Syntax

def get_remote_host() -> str: ...
def set_remote_host(value: str) -> None: ...

remote_host = property(get_remote_host, set_remote_host)

Default Value

"255.255.255.255"

Remarks

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

remote_port Property

This property sets a specific port for outgoing log packets.

Syntax

def get_remote_port() -> int: ...
def set_remote_port(value: int) -> None: ...

remote_port = property(get_remote_port, set_remote_port)

Default Value

514

Remarks

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

ssl_accept_server_cert_effective_date Property

The list_store_certificates method may be called after setting cert_store_type to cstPKCS11, cert_store_password to the PIN, and cert_store to the full path of the PKCS#11 DLL. The certificate information returned in the on_cert_list event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the ssl_server_cert_store and set ssl_server_cert_store_password to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

activate Method

This method enables sending and receiving of data.

Syntax

def activate() -> None: ...

Remarks

This method enables sending and receiving of data. When called, the class 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 class to send and receive data.

If the UseConnection configuration setting is set to True, then a local association (connection) to the remote host is also created.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

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.

deactivate Method

This method disables sending and receive of data.

Syntax

def deactivate() -> None: ...

Remarks

This method disables sending and receiving of data. When called, the class will destroy the existing socket and disable data communications.

do_events Method

This method processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

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

reset Method

This method will reset the class.

Syntax

def reset() -> None: ...

Remarks

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

resolve_remote_host Method

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

Syntax

def resolve_remote_host() -> None: ...

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 class 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

This method sends a log packet to RemoteHost .

Syntax

def send_packet(facility: int, severity: int, message: str) -> None: ...

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:

0Kernel messages
1User-level messages
2Mail system
3System daemons
4Security/authorization messages
5Messages generated internally by syslogd
6Line printer subsystem
7Network news subsystem
8UUCP subsystem
9Clock daemon
10Security/authorization messages
11FTP daemon
12NTP subsystem
13Log audit
14Log alert
15Clock daemon
16Local use
17Local use
18Local use
19Local use
20Local use
21Local use
22Local use
23Local use

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

0Emergency - the system is unusable
1Alert - action must be taken immediately
2Critical - critical conditions exist
3Error - error conditions exist
4Warning - warning conditions exist
5Notice - normal but significant condition
6Informational - informative message
7Debug - debug-level messages

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

@property
def on_packet_in() -> Callable[[SysLogPacketInEventParams], None]: ...
@on_packet_in.setter
def on_packet_in(event_hook: Callable[[SysLogPacketInEventParams], None]) -> None: ...

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:

0Kernel messages
1User-level messages
2Mail system
3System daemons
4Security/authorization messages
5Messages generated internally by syslogd
6Line printer subsystem
7Network news subsystem
8UUCP subsystem
9Clock daemon
10Security/authorization messages
11FTP daemon
12NTP subsystem
13Log audit
14Log alert
15Clock daemon
16Local use
17Local use
18Local use
19Local use
20Local use
21Local use
22Local use
23Local use
SeverityCode is a value from 0 to 7. Severity is a string representation of SeverityCode using the following convention:
0Emergency - the system is unusable.
1Alert - action must be taken immediately.
2Critical - critical conditions exist.
3Error - error conditions exist.
4Warning - warning conditions exist.
5Notice - normal but significant condition.
6Informational - informative message.
7Debug - 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.

on_ssl_client_authentication Event

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

Syntax

class SysLogSSLClientAuthenticationEventParams(object):
  @property
  def remote_address() -> str: ...

  @property
  def remote_port() -> int: ...

  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class SysLog:
@property
def on_ssl_client_authentication() -> Callable[[SysLogSSLClientAuthenticationEventParams], None]: ...
@on_ssl_client_authentication.setter
def on_ssl_client_authentication(event_hook: Callable[[SysLogSSLClientAuthenticationEventParams], None]) -> None: ...

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 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.

on_ssl_server_authentication Event

This event fires when connecting to the server.

Syntax

class SysLogSSLServerAuthenticationEventParams(object):
  @property
  def remote_address() -> str: ...

  @property
  def remote_port() -> int: ...

  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class SysLog:
@property
def on_ssl_server_authentication() -> Callable[[SysLogSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[SysLogSSLServerAuthenticationEventParams], None]) -> None: ...

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.

on_ssl_status Event

This event shows the progress of the secure connection.

Syntax

class SysLogSSLStatusEventParams(object):
  @property
  def remote_address() -> str: ...

  @property
  def remote_port() -> int: ...

  @property
  def message() -> str: ...

# In class SysLog:
@property
def on_ssl_status() -> Callable[[SysLogSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[SysLogSSLStatusEventParams], None]) -> None: ...

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.

SysLog Config Settings

The class 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 class, access to these internal properties is provided through the config method.

TCPMessageDelimiter:   The message delimiter to use (if any) when sending and receiving over TCP.

When use_tcp 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 use_tcp 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 class 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 should be set before setting any of the AppName, MsgId, ProcId

UDP Config Settings

CaptureIPPacketInfo:   Used to capture the packet information.

If this is set to True, the component will capture the IP packet information.

The default value for this setting is False.

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 remote_host is set. If True the class will resolve the hostname and the IP address will be present in the remote_host 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, resolve_remote_host may be called to manually resolve the value in remote_host at any time.

The default value is False.

DestinationAddress:   Used to get the destination address from the packet information.

If 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 class 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 local_host 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 class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the local_host 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 class binds.

This configuration setting 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 local_port after the connection is established.

local_port 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 class will accept without truncation.

QOSDSCPValue:   Used to specify an arbitrary QOS/DSCP setting (optional).

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 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 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.

SourceIPAddress:   Used to set the source IP address used when sending a packet.

This configuration setting can be used to override the source IP address when sending a packet.

Note: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).

SourceMacAddress:   Used to set the source MAC address used when sending a packet.

This configuration setting can be used to override the source MAC address when sending a packet.

Note: This configuration setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).

UseConnection:   Determines whether to use a connected socket.

UseConnection specifies whether or not the class 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 class 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 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 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. 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 class 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).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. 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.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to False, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to True tells the class 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 section.
