Python Gets the native IP, MAC address, computer nameGetting an IP address in Python is a big difference in PHP, so let's take a look at Python's native MAC address:>>> Import UUID>>> def get_mac_address ():Mac = uuid. UUID (int = Uuid.getnode ()). HEX[-12:]Return ': '. Join

Early in the use of PHP is not known to have filter this thing, at that time to determine whether the mailbox, URL and IP address format is consistent with the regular expression. Later, as the use of gradually deepened, I know in PHP can also use the built-in function library filter to complete these functions. 1, verify the mailbox First look at the original regular validation The code is a

This article introduces how Iptables limits the number of connections of the same IP address in linux to prevent CC/DDOS attacks. This is only the most basic method. If the attack is real, we still need hardware compaction to prevent it. 1. Set the maximum number of connections to port 80 to 10, which can be customized. The Code is as follows: Copy code Iptables-I INPUT-p tcp -- dpor

However, sometimes, as the ZooKeeper administrator, some features are required:For example, you can use a specified ip address to reject connection and operation requ

The IPV4 address is actually a 32-bit binary number, and then we divide it into four segments, 8 bits per paragraph. The 8-bit binary can be expressed in a range of 0~255, so that every digit in the dotted decimal system is 0~255. Sometimes, for example, in order to convert the subnet mask, we need to restore the IP address
