the SMB type is confirmed, the client sends the session Setup command packet, submits the account number, the password, and requests a connection to the Samba server. If the client is authenticated, the Samba server responds to the session setup message and assigns the user a unique UID to communicate with the client.(3) Access to shared resources: When a client accesses a Samba shared resource, it sends a Tree Connect command packet, notifies the server of the shared resource name that it need

If your operating system does not have VIM installed, you will need to manually install vim yourself. get vim in Unix and gnu/linux environments:A certain version of Vim is now attached to many UNIX environments, and most gnu/linux distributions link the default VI location "/BIN/VI" to the Vim executable file. But there are many variants of Unix, and Gnu/linux has many distributions, if your unix-li

storage medium for data sharing between servers, such as storing data in the SSO system as a single-point login, which can be saved in memcached and shared by multiple applications.　　Applications because memcache are distributed, you can provide shared resources for different servers in a Web project. Because memcache is storing data directly in memory, in order to reduce the pressure of the database, you can add a layer of memcache cache between the Web and the database. And in Memcache, the d

These are the two tool classes that manipulate arrays and collections.Third, collection interface and Abstractcollection class1, Introduction: Collection interface is the root interface of processing object collection. The Abstractcollection class is a convenient class that provides a partial implementation of the Collegetion interface."interface" boolean

With the development of computer network technology, Wireless LAN has become a high-speed development of wireless communication technology in the computer network to achieve communication mobility, personalization and multimedia applications. However, because the transmission media of wireless communication is the air with no entity protection, the data sent by wireless can reach all the terminals within the coverage range, or it is an unexpected receiving device, which provides more and more co

language, assembly instruction is the mnemonic of machine instruction, Each assembly instruction has a corresponding machine instruction, which is a great boon for programmers, who do not need to remember the boring 01 sequences. The advent of assembly language does largely liberate programmers, but what we need to know is that computers only know 01 sequential columns, machine instructions, We do not know the assembly instructions we write, to enable the computer to perform the assembler we h
