How to configure BSD-syslog and IETF-syslog message formats in Syslog-ng -
Descrizione
This knowledge shows how to configure BSD-syslog (RFC 3164) and IETF-syslog (RFC 5424) message formats in Syslog-ng Premium Edition (PE) through some basic example configurations.

Risoluzione
Configuring BSD-syslog (RFC 3164) format
Source configuration
The network() source driver can receive syslog messages conforming to RFC3164 from the network using the TCP, TLS, and UDP networking protocols.
- Default settings: listening on every available IPV4 interface on the TCP/514 port.
source s_network {
network();
};- UDP source listening on 192.168.1.1 (the default port for UDP is 514):
source s_network {
network( ip("192.168.1.1") transport("udp") );
};For more details about network() source driver see the following documentation.
Syslog-ng PE 6: Collecting messages using the RFC3164 protocol (network() driver)
Syslog-ng PE 7: network: Collecting messages using the RFC3164 protocol (network() driver)
Destination configuration
The network() destination driver can send syslog messages conforming to RFC3164 to a remote server using the TCP, TLS, and UDP networking protocols. It has a single required parameter that specifies the destination host address where messages should be sent.
- TCP destination that sends messages to 10.1.2.3, port 514:
destination d_tcp {
network("10.1.2.3");
};- UDP destination that sends messages to 10.1.2.3, port 1999:
destination d_udp {
network("10.1.2.3" port(1999) transport(udp) );
};For more details about network() destination driver see the following documentation.

Syslog-ng PE 7: network: Sending messages to a remote log server using the RFC3164 protocol (network() driver)
Syslog-ng Agent for Windows
- Navigate to the destination server and open Properties
- Add IP the address of the syslog server
- Set port 514 as Server port
- Select 'Legacy BSD Syslog Protocol' at Messages tab | Protocol
Configuring IETF-syslog (RFC 5424) format
Source configuration
The syslog() driver can receive messages from the network using the standard IETF-syslog protocol (as described in RFC5424-26). UDP, TCP, and TLS-encrypted TCP can all be used to transport the messages.
- Default settings: listening on every available IPV4 interface on the TCP/601 port.
source s_syslog {
syslog();
};- TCP source listening on 192.168.1.1 on port 1999.
source s_syslog {
syslog( ip(192.168.1.1) port(1999) transport("tcp") );
};For more details about syslog() source driver see the following documentation.
Syslog-ng PE 6: Collecting messages using the IETF syslog protocol (syslog() driver)
Syslog-ng PE 7: syslog: Collecting messages using the IETF syslog protocol (syslog() driver)
Destination configuration
The syslog() driver sends messages to a remote host using the IETF syslog format. It has a single required parameter that specifies the destination host address where messages should be sent.
- TCP destination that sends messages to 10.1.2.3, port 514:
destination d_tcp {
syslog("10.1.2.3");
};
- TCP destination that sends messages to 10.1.2.3, port 1999:
destination d_tcp {
syslog("10.1.2.3" port(1999) );
};
For more details about network() destination driver see the following documentation.

Syslog-ng PE 7: syslog: Sending messages to a remote logserver using the IETF-syslog protocol
Syslog-ng Agent for Windows
- Navigate to the destination server and open Properties
- Add the IP address of the syslog server
- Set port 601 as Server port
- Select 'Syslog Protocol' at Messages tab | Protocol
Collecting non-syslog messages
- The no-parse flag completely disables syslog message parsing and processes the complete line as the message part of a syslog message.
- The syslog-ng PE application will generate a new syslog header (timestamp, host, and so on) automatically and put the entire incoming message into the MESSAGE part of the syslog message (available using the ${MESSAGE} macro).
- Warning! Do not receive both syslog and non-syslog messages on the same source. Instead create separate source for both format.
BSD-syslog
source s_network {
network( ip("192.168.1.1") flags(no-parse) );
};IETF-syslog
source s_network {
syslog( ip("192.168.1.1") flags(no-parse) );
};
