Subject: Microsoft Daytona TCP-IP name resolution ques.

Using the Microsoft "Daytona TCP/IP" and WFW 3.11 and ODI drivers..... I find
that if I telnet to a local host by only specifying the Host name (ie:YALEVM)
, I get rejected saying "Unable to resolve hostname" however if I telnet to
(ie: YALEVM.YCC.YALE.EDU) i am able to connect.

I had thought that by configuring the Domain Name Servers, and by specifying
the default domain name (ie: YCC.YALE.EDU) - which I did after "adding a
protocol" I would be able to connect via the Hostname only?

This is how the Trumpet Winsock handles things, what might I be missing?
should there be some sort of HOSTS file in the Windows directory?

-thanks,  [e-mail]

Subject: winsock programming problem

I am just starting out with winsock programming and I'm having problems.
At this point I am just trying to establish a connection with a host
(IP = 130.41.1.250).  I am using the following pascal code and I get
an error # 10047 on the bind command (I get the same error if I replace
the bind with a connect).  This error, WSAEAFNOSUPPORT, means the
specified address family is not supported by this protocol.  I have
verified that several other working winsock apps doexactly the same
winsock calls with the same parameters to the the socket call.  I suspect
there is something wrong with the name parameter I am supplying to bind.
The pascal header is a little different than the C header concerning the
'sockaddr' format - the pascal just shows it as a family followed by 14
bytes of data.  I am filling them like the 'sockaddr_in' format - a
2 byte port, 4 byte IP address, 8 bytes of ZERO (?).

Thanks for any help you can give.

Greg


program wsocktst;

uses winsock, wincrt;

var
  i:            integer;
  wsadata:      lpwsadata;
  skt:          socket;
  socka:        sockaddr;
  psocka:       psockaddr;


begin
  socka.sa_family := AF_INET;
  socka.sa_data[0] := #25;            {these next two bytes should be the SMTP port}
  socka.sa_data[1] := #0;            { (I also tried 119)}

  socka.sa_data[2] := #130;        {the next four bytes are the IP address}
  socka.sa_data[3] := #41;
  socka.sa_data[4] := #1;
  socka.sa_data[5] := #250;

  for i := 6 to 13 do            {don't know what these are for}
    socka.sa_data[i] := #0;

  i := wsastartup(257,@wsadata);
  writeln('WSAStartup = ',i);        {this gives me a return code of 0, so far so good}

  skt := _socket(2,1,0);
  writeln('Socket = ',skt);            {this gives me a return code of 1, still OK}

  i := bind(skt,socka,16);
{  i := connect(skt,socka,16);     both give the same result}
  writeln('Bind = ',i);            {this gives me an error response of -1}

  if i <> 0 then
    i := wsagetlasterror;
  writeln('Bind Error = ',i);        {the actual error code is 10047}

  WSACleanup;

end.
