Computer intelligence and Network processes have contributed to the rapid rise and wide application of Agent technology. Mobile Agent technology is a new computing method for solving complex, dynamic, and distributed intelligent applications, it is another profound change in computer software technology.
This series of articles introduces the new intelligent distributed computing model of mobile

SSH is short for Secure Shell, developed by the Network Working Group of IETF. SSH is a security protocol built on the application layer and transport layer.

What is the security comparison between FTP and SSH?
Ftp:
Http://baike.baidu.com/subview/369/6149695.htmIn the TCP/IP protocol, the FTP standard command TCP port number is 21,port mode with a data port of 20. The task of FTP is to transfer files from one computer to another computer, without the limitation of the operating system.
The computer that requires remote file transfer must have the FTP client installed and running.

Preface
I don't need to talk about the benefits of SSH?
In short, the previous RPC command and telnet are all replaced by SSH.
For example, the following common functions:
-Remote Logon
SSH user@remote.machine
-Remote Execution
SSH user@remote.machine 'COMMAND ...'
-Remote replication

Enable the SSH service and enable ssh
The SSH service is applicable to all UNIX-like systems, such as Ubuntu, CentOS, and RedHat, including Mac OX. Here we will briefly introduce some of its applicable methods.
First, we will introduce Mac OX. Because SSH is embedded on the Apple system, you don't need to install anyt
About git ssh-key: solves the problem of multiple local ssh-keys, gitssh-keyWhen setting github, the official instructions require that the current id_rsa be backed up and a new private key be generated for github login. If this is done, the new private key cannot continue to log on to the previous machine. This method is a bit violent...Fortunately, ssh allows u
If you just want to use level two agents, this software is much more convenient than SOCKS2HTTP+SOCKSCAP32. As for the other functions of the httport, I slowly groping it, for this aspect of the inquiry, do not reply! Of course, there is a premise that you use the first level agent to support SSL, in fact, in the Socks2http agent also has this requirement. That's why some agents can't be used in socks2http.

Trivial-do you want to set SSH password-free or ssh-free?
Hadoop2.2.0 has been set up many times, and many different startup methods, configuration parameters, and locations have been tried, which involves whether to configure SSH password-free logon or not.
First, find out why SSH password-free login is required.
Remote Assistance Based on ssh reverse proxy and ssh reverse assistance
This article describes how to implement remote assistance through ssh reverse proxy and provides relevant code.
After Remote Assistance is enabled on the web, maintenance personnel can log on to the customer's machine through ssh and http (includin
1.1 mobile agent platform Analysis and Comparison
Although the essence of the mobile agent is the status when the mobile code and code are suspended, that is, when the object is moved from one host to another, we can implement it ourselves, for example, Java can be implemented through the serialization mechanism of Java. In C ++, we can also use DCOM. However, to implement mobile agents, we generally need t
Ssh password-free login, ssh password login
Assume that the master machine A, B, and C needs to be established as the master machine A. You can directly access the master machine B and C through ssh without A password. The procedure is as follows:
Assume that you only use the user yimr to establish trust, use the yimr user to log on to host A and perform the foll
Ssh certificate verification login, ssh certificate verification
Generally, PuTTY and other SSH clients are used to remotely manage Linux servers. However, a common Password Logon method is prone to brute force password cracking. Therefore, we usually set the SSH port to a port other than 22 by default, or disable root
The definition of SSH on Wikipedia is as follows:
Secure Shell (SSH) is developed by the Network Working Group of IETF. SSH is a security protocol built on the application layer and transport layer, provides a secure transmission and use environment for the Shell layer on the computer.Install the ssh server and install
How to use a one-time password to securely log on to Linux through SSH, and use a password to log on to linux through ssh
Some people say that security is not a product, but a process. Although the SSH protocol is designed to use encryption technology to ensure security, if improperly used, others can still damage your system, such as weak passwords, key leaks, a
Principle:
Key authentication needs to rely on the key, first create a pair of keys (including public keys and keys, and the public key encrypted data can only be decrypted with the key), and put the public key to the need for a remote server. This way, when you log on to a remote server, the client software sends a request to the server requesting authentication with your secret key. After the server receives the request, first in the host directory of the server you look for your public key, a
