Socket Timeout

[peterchen25]

Socket timeouts are not set, therefore the connect could get stuck in case of bad ip or drop of network connection.
Suggestion:
After creating the socket

struct timeval timeout{TIMEOUT_S,TIMEOUT_US};
setsockopt (sock, SOL_SOCKET, SO_SNDTIMEO, (char *)&timeout,sizeof(timeout));
