Hi
First of all, if you are no longer in 6.906/6.033 lab, let me know if you
want to be removed from the mailing list.
A couple of things:
- The following code segment will allow you to terminate your proxy
server and restart it again w/o your system complaining that the server
is trying to reuse a port number. Here, s is the descriptor you got
from socket.
{
int v = 1;
setsockopt(s, SOL_SOCKET, SO_REUSEADDR, (char*)&v, sizeof(v));
}
Include this code before call to bind. It tells the kernel that you
are allowed to reuse an address with this socket.
- If you are still uncertain about what you are suppose to do with your
tcp proxy, please let me know.
- I will have office hours on Tues (virtual Monday), so please come and
see me if you have questions.
Benjie
