ubuntu installation using SSH
The Ubuntu default does not have SSH service installed, and if you link Ubuntu via SSH, you will need to manually install Ssh-server. To determine whether to install the SSH service, you can do so by

In the build environment, the server's password is often modified to ensure security and can be scripted with the shell.Using SSH to directly modify the password of the other server can be implemented with the SSH username @ login IP followed command, but requires the administrator to enter a password to operate, in order not to let the administrator manually input so solve this scenario with expect, bec
1. Multiple Connection Sharing
If you need to open a connection to the same server in more than one window, instead of typing the username, password, or waiting for the connection to be established each time, you can configure the SSH Connection Sharing option to open your SSH profile locally, usually in ~/.ssh/config, and then add the following 2 lines:

File Transfer
Connection sharing not only helps you share multiple SSH connections. If you need to transfer files with the server through SFTP, you will find that they are still using the same connection, if you use Bash, you will find that you even support Automatic completion of server files by

a pair of keys (private key + public key) to place the public key on the server registration. When a user logs on to a server from a client, the server receives a security authentication request using the key (that is, the public key registered on the server), the server is first compared to the public key that is sent from the client and the public key registered with the client, and if it is consistent, the server uses that public key to encrypt da
Upload and download server files via SSH
It's written in front of you.
Previously recorded a use of Apache FTP open source components to implement server file upload download method, but later found that the deletion of some permissions problems, resulting in the server can not delete files. Although it is OK to use FileZilla server to set read and write permissions on Windows, it is still a bit of a bad idea on the server side.
Because they need t
Log on to the Linux server using SSH without a password
In the following example, ssky-keygen and ssh-copy-id can be used to log on to a remote Linux host without a password.Ssh-keygen creates the public key and key.Ssh-copy-id copies the public key of the local host to the authorized_keys file of the remote host.The ssh
Precautions for logging on to a remote host using SSH without a password
The latest project should be combined with rabbitmq, keepalived, and supervisor. In one scenario, after a keepalived instance is promoted to a MASTER instance, it needs to kill these client processes on the remote host where the rabbitmq client is deployed.
The general idea is to configure a password-less

Find "#" at the beginning of the line "#" in "# PermitRootLogin", and change "yes" to "no" to disable root logon; find # PasswordAuthentication yes remove the first line "#", change yes to no do not allow password login; find # PermitEmptyPasswords no remove the first line "#", disable empty password login)6.

SSH is a reliable protocol designed for remote logon sessions and other network services. The SSH protocol can effectively prevent information leakage during Remote Management.

Method 1: Use puttygen.exe
Step 1: generate a keyRun puttygen.exe, select the type and length of the key, and use the default SSH2 (RSA). Set the length to 1024.Passphrase can be blank to avoid entering a password at login.
