I used setsockopt to set the timeout value;
struct timeval tv;
tv.tv_sec = 20;
tv.tv_usec = 0;
cout << setsockopt (sockID, SOL_SOCKET, SO_RCVTIMEO, &tv, sizeof tv ) << endl;
cout << perror("setsockopt") << endl;
The error it gives is this option is not supported .
What can I do to enable this option.

Hi Afernando,
You could check if your Operating System at the specific level supports SO_RCVTIMEO. At some older levels of OS's these settings are fixed settings and cannot be altered or even read.
The syntax seems correct. Could it be for a specific socket type this option is not supported?
Good luck!
Yes you do need superuser rights for some operations but in this case even superuser rights will not help as implementation of sockets does not support the operation ...
If it setsockopt fails for permission issues, appropriate error EPERM is treturned ... Here this is not the case.
Check the man page for your distribution to verify if it supports the options

Hi afernando,
perhaps you meant to organize it this way
int ret;
ret = setsockopt (sockID, SOL_SOCKET, SO_RCVTIMEO, &tv, sizeof tv );
if ( ret != 0 )
cout << perror("setsockopt") << endl;
your current code will print an error meessage even if the call succeeds
Cheers!
