Hello all,

I am attempting to socket from a win95 pc to an as400. Both systems are on the 
same local ethernet lan. Both behind the firewall.
When I run connect( ) on the pc, a "WSAECONNREFUSED" ( the attempt to connect 
was forcefully rejected ) error code is returned.

My "Listen" pgm is running on the as400.  It was able to rcv data on a loopback 
test, so I am reasonably sure it is coded correctly.

Do I have to enable anything on the 400 or pc before socketing from one system 
to the other?  Any ideas?  Why the WSAECONNREFUSED error?

Does the 400 log socket connection attempts that are refused?

Thanks,
Steve Richter

Here is the code.  First the c code on the pc, then the rpg ile as400 code.

{
SOCKET hSock;
SOCKADDR_IN addr ;
WSADATA wsaData ;
int nRc ;
CString sError ;
WORD wWsaVer ;

wWsaVer = MAKEWORD( 2, 2 ) ;
nRc = WSAStartup( wWsaVer, &wsaData ) ;

hSock = socket (AF_INET, SOCK_STREAM, 0) ;
FillMemory( &addr, sizeof(addr), 0 ) ;
addr.sin_family = AF_INET ;
addr.sin_addr.s_addr = inet_addr( "172.xx.y.z" ) ;
addr.sin_port = 3005 ;
nRc = connect( hSock, (LPSOCKADDR)&addr, sizeof(addr) ) ;
if ( nRc != 0 )
{
sError = subsGetSocketError( ) ;
subsMessageBox( sError, "Socket Error" ) ;
}
nRc = WSACleanup( ) ;
return ;
}

** Create the socket.                                                
 C                   Eval      SD = Socket (AF_INET: SOCK_STREAM: 0 )

 ** If socket failed - End the server program with dump               
 C                   If        SD < 0

 c                   EndIf
