Re: [B.A.T.M.A.N.] [RFC] alfred: implement TCP support for server-to-server communication

+int connect_tcp(struct interface *interface, const struct in6_addr *dest) +{

• struct sockaddr_in6 dest_addr;
• int sock;
• memset(&dest_addr, 0, sizeof(dest_addr));
• dest_addr.sin6_family = AF_INET6;
• dest_addr.sin6_port = htons(ALFRED_PORT);
• dest_addr.sin6_scope_id = interface->scope_id;
• memcpy(&dest_addr.sin6_addr, dest, sizeof(*dest));
• sock = socket(PF_INET6, SOCK_STREAM, IPPROTO_TCP);
• if (sock < 0)

• return -1;
  

• if (connect(sock, (struct sockaddr *)&dest_addr,

•     sizeof(struct sockaddr_in6)) < 0) {
  

• close(sock);
  

• return -1;
  

• }
• return sock;

+}

Wouldn't this hang for a while and make the alfred server "unresponsive" when the remote is not reachable at this moment?.

Kind regards, Sven
