Hi,

I would like to know the IP address of the machine that sent a given syslog message (similar to recvfrom).
https://linux.die.net/man/2/recvfrom

How can this be done?

I can see there is a hostname field, but this value is optional and it is not necessarily the same thing.

Thanks in advance,

Toby

The MessageReceived event arguments provide the RemoteEndPoint property that can be used to retrieve the remove machine's IP address and port:

// create a server instance
var server = new SyslogServer();

// bind endpoints
server.Bind(SyslogServer.DefaultPort, SyslogTransportProtocol.Udp);
server.Bind(SyslogServer.DefaultPort, SyslogTransportProtocol.Tcp);

// register an event handler for received messages
server.MessageReceived += (s, e) =>
{
    Console.WriteLine("Message from {0}: {1}", e.RemoteEndPoint.Address, e.Message.Text);
};
