Hi Morten,
If you want to listen to the 514 port, you does not need to connect to the
address.
You can simply do like this:
try
{
UdpClient udpClient;
IPEndPoint IPEnd;
udpClient = new UdpClient( 514);
IPEnd = new IPEndPoint( IPAddress.Any,514);
byte[] recv = udpClient.Receive( ref IPEnd ); // <<<<< I NEVER GET PAST
THIS
string str=Encoding.Unicode.GetString(recv);
Console.WriteLine(str);
}
catch(Exception ex)
{
Console.WriteLine (ex.Message );
}
I have downloaded Kiwi Syslog Daemon, when I sent text message to local
host, my
application succeeded receiving the data.
If there is still any problem, please feel free to let me know.
Best regards,
