I had better luck compiling the cyberphreak version (have since managed to
compile several flavors), but it still only seems to DoS patched and
unpatched systems.  
The code gets stuck in a loop and always produces error 10054.  Any idea
what that means?

 if(ft) 
         { 
              int i=0; 
              while(1) //this seems to be an endless loop, till a error
apears!! 
              { 
                   if (send(sock,(const char *)buf2,len1,0)==SOCKET_ERROR) 
                   { 
                        printf("\nSend
failed.Error:%d\n",WSAGetLastError()); 
                        return 0; 
                   } 
                   else 
                   { 
                  printf("\rStatus: %d",++i); 
                   } 
                   //Sleep(1000); 
              } 
           
         }

Just out of curiosity could you specify why you consider the other one 
"better code?"  The only real differences between the two are that they 
both "fix" the 'cs+=buf;' line differently which is kind of silly to 
bother fixing in the first place, considering the function that line of 
code sits on isn't even called so it should be commented out or deleted 
to start with.  The only other real difference is one decided to use an 
int main and one uses void main.  Well that and the SecurityLab copy 
breaks part of main with the 'if(argc!=2){' check, as it is meant to 
have two different modes of operation, one target or a class B.
