if i manually modify source code and simply set tos directly. where should i add it. now I'm adding:
# tcp_proto.c, tcp_connect_server, line 513 - 514. 511 if (global.tune.server_rcvbuf) 512 setsockopt(fd, SOL_SOCKET, SO_RCVBUF, &global.tune.server_rcvbuf, sizeof(global.tune.server_rcvbuf)); 513 int tos=0x10; 514 setsockopt(fd, IPPROTO_IP, IP_TOS, &tos, sizeof(tos)); 515 if ((connect(fd, (struct sockaddr *)&conn->addr.to, get_addr_len(&conn-> addr.to)) == -1) && is it correct? seems it works now, but i don't know if it will cause other problem. my goal is make all backend side connection have a specific TOS field. for policy routing like this: # ip route add default via 10.1.0.1 tos 0x10.
