What version of the product are you using? On what operating system?
I'm using tcpcopy 0.3.5 and Ubuntu 11.10 x64 Linux 3.0.0-12-server.

Thanks for reporting the bug.
It may be a common problem for Ubuntu 11.10.

You can add one-line code in sock_bind function

static void sock_bind(int sock){
    struct sockaddr_in local_addr;
    socklen_t length; 
    memset(&local_addr,0,sizeof(local_addr));
    local_addr.sin_port = ntohs(SERVER_PORT);
    local_addr.sin_family= AF_INET;   //add this line for Ubuntu 11.10
    length = (socklen_t)(sizeof(local_addr));
    if(bind(sock,(struct sockaddr *)&local_addr,length)==-1){
        perror("can not bind:");
        logInfo(LOG_ERR,"it can not bind address");
        exit(errno);
    }else
    {   
        logInfo(LOG_NOTICE,"it binds address successfully");
    }   
}

Check if it is working.

Thanks again
