Hi All
I have a problem about OpenSSL proxy server rebooting.
OpenSSL proxy server could not be restarted after killing, and I find the
root cause:
On Linux OS, if there is a socket binding a port, after the socket is closed
or the program exit normally, the port could not be release at once, if I
restart the OpenSSL proxy server it will report binding error, the address
could not be used at once.
I add the method "setsockopt" to resolve this issue after the socket created
and before binding the port in method "server_init", please see the follows,
the blue line is added by us.
server_socket=socket(AF_INET, SOCK_STREAM, 0);
if (server_socket<0) {
perror("socket()");
exit(1);
}
server.sin_family=AF_INET;
inet_pton(AF_INET, addr, &ipaddr);
server.sin_addr.s_addr=ipaddr;
// server.sin_addr.s_addr=htons(INADDR_ANY);
server.sin_port=htons(port);
z = setsockopt(server_socket, SOL_SOCKET, SO_REUSEADDR, &so_reuseaddr,
sizeof so_reuseaddr);
if (z==-1)
{
perror("setsockopt(SO_REUSEADDR)");
}
if (bind(server_socket, (struct sockaddr *)&server, sizeof(server)) < 0)
{
perror("bind()");
exit(1);
}
And then, I could restart the OpenSSL proxy server.
Why the bug is not fixed, and is there any risk of adding the above change?
Or would you like to give another way to resolve this issue? Thank you very
much.
Best wishes,
Daobang.
