Hello ML
I have the program for scan ports, in the which there is :
        sin.sin_family=AF_INET;
        sin.sin_port=htons(110);
        sin.sin_addr.s_addr=htonl(counter);
        addr.s_addr=htonl(counter);
        bzero(&(sin.sin_zero),
8);
       Â
        if
(connect(sock, (struct sockaddr*)&sin, sizeof(sin))==0)
        Â
{
         Â
read(sock, buffer, sizeof(buffer));
         if
(strstr(buffer, "QPOP") != NULL)
          Â
{
             Â
fprintf(stdout, "FOUND : %s\n", inet_ntoa(addr));
          Â
}
         }
With gcc -g -oprova prova.c  is ok!
No error.
When run the program (prova) in the gdb, subsequently line
 if (connect(sock, (struct sockaddr*)&sin,
sizeof(sin))==0)
write the command print connect.
The result is :
$1 = {< text variable, no debug info >} 0x400c9ca0
<__libc_connect>
Why ?
The result of connect no egual -1 (error connecting) or 0 (connecting ok)
?
Help me
Thanks
