First of all, we need to understand the IP address conversion to the integral type (strictly speaking is a long integer) the principle of ~
"Principle of conversion": assuming the IP is: w.x.y.z, the IP address to the integer number of the calculation formula: Intip = 256*256*256*w + 256*
.
Asymmetric encryption algorithm that uses two pairs of keys that are completely different but perfectly matched: the public key and the private key. When encrypting a file using an asymmetric encryption algorithm, the process of encrypting and decrypting the plaintext is accomplished only by using a matching pair of public and private keys.

To modify the module scsi_mod, add max_luns = 512, redo the guided initrd image, and add the module parameter changes to initrd. This is certainly no problem. This can be done.

information: Century, year, month, date, hour, minute, and second. Typically consumes 7 bytes of storage space. 3.2 Timestamp type This is a 7-byte or 12-byte fixed-width date/time data type. It differs from the date data type because timestamp can contain fractional seconds, and timestamp with fractional seconds can hold up to 9 digits to the right of the decimal point 3.3 TIMESTAMP with time zone type This is a variant of the timestamp type, which contains the value of the time zone offset 3.
-defined tree based on the frequency of occurrence, and generates a user-defined code based on the user-defined tree. Scan the file again, read 8 bits each time, match the encoding according to the "character-encoding" table, save the encoding to the compressed file, and store the encoding table. During decompression, read the encoding table, read the encoding matching encoding table, find the corresponding characters, store the files, and decompress the files.
