. Guard against Kismet: There is no way for Kismet to find your WLAN, so be sure to have advanced authentication and encryption measures. Guard against Airsnort: use a 128-bit, rather than 40-bit WEP encryption key, which can take longer to crack. If your device is supported, use WPA or WPA2, and do not use WEP. Guard against Cowpatty: Choose a long complex WPA shared key. The type of the key is not likely to exist in the hacker-induced file list, so the attacker can guess your key will take

/opt/www/lk, is not in the main directory/var/www/html can not access it? Of course not.You can use a virtual directory to allow users to access files in other directories. The virtual directory is a directory that is located outside of the Apache home directory, and we typically make the web accessible by creating an alias for the virtual directory. It is safe to do this, the second is to access the simple, do not enter so long is the directory address, but only with the input of a simple alias

building high-performance, highly scalable Internet applications-because it handles massive and high-throughput concurrent connections.How it works is quite interesting. The traditional Network Service technology, is each new connection (request) will generate a new thread, this new thread will occupy the system memory, will eventually take up all the available memory. While node. JS is only running in one single thread, using non-blocking asynchronous I/O calls, all connections are handled by
