The SSH full name Secure Shell, as its name implies, is the meaning of a very secure shell, an agreement developed by the network Working Group of the IETF (Internet Engineering Task Force). SSH's main purpose is to replace the traditional Telnet and R series commands (rlogin,rsh,rexec, etc.) remote login and remote execution of command tools, remote login and remote command encryption. It is a threat to the system by preventing the leakage of passwor

Take out the ssh-agent, because as the company's springboard program is implemented, Ssh-agent will be used on a large scale or covertly. Understanding how it works helps me understand the deployment and operations involved, and how to safely drop applications.

The new server OS uses the Ubuntu Server version, which is a lot different from the familiar CentOS. In peacetime work, we log on to the server, is generally the way to use the SSH password. In fact, there is another way, that is, through the SSH key to the server. Both of these methods are security authentication methods of SSH, and according to the different au

Ssh port forwarding details Ssh is a multi-purpose tool. It not only supports remote logon, but also supports socks proxy and Intranet penetration. This is achieved through its port forwarding function. The so-called ssh port forwarding refers to specifying a port of the ssh client or

Using an SSH client (such as: Putty) to connect to a Linux server may wait 10-30 seconds to prompt for a password. Seriously affect work efficiency. Logon is slow, log on after the normal speed, this situation is mainly for two possible reasons: 1. DNS Reverse resolution problem OpenSSH when the user log in to authenticate the IP, it is based on the user's IP using reverse DNS to find the host name, and then use DNS to find the IP address, and final

Configure SSH for user equivalenceDuring Oracle RAC 10g installation, oui needs to copy files to other hosts in the cluster and execute programs on them. To allow Oui to complete this task, you must configure SSH to enable user equivalence. Using SSH to establish user equivalence provides a safe way to copy files and execute programs on other hosts in the cluster

SSH port forwarding Through the introduction in this article, you can learn how to apply the SSH port forwarding mechanism to solve some problems in daily work/life. Learn to use port forwarding in a non-secure environment to encrypt network applications and protect personal privacy and important business information. At the same time, this technology can also be used to solve some common problems in the wo

Configure the SSH service to log on to the Linux server using the certificate Common authentication methods for logging on to a Linux server through SSH (Secure Shell) include passwords and certificates. From the security perspective, we recommend that you log on with a certificate. It takes a lot of effort to configure SSH login using a certificate on the server
