Hello,

I am using Delphi and I want to determinate the physical MAC address of a network device in my network, in this case the Router itself.

My code:

var
  idsnmp: tidsnmp;
  val:string;
begin
  idsnmp := tidsnmp.create;
  try
    idsnmp.QuickSend('.1.3.6.1.2.1.4.22.1.2', 'public', '10.0.0.1', val);
    showmessage(val);
  finally
    idsnmp.free;
  end;
end;

where 10.0.0.1 is my router.

Alas, QuickSend does always send "Connection reset by peer #10054". I tried to modify the MIB-OID and I also tried the IP 127.0.0.1 which connection should never fail. I did not find any useable Tutorials about TIdSNMP at Google. :-(
