SSH is not installed on Aix by default, which makes me very depressed. Xmanager is used to remotely accessing the server through SSH protocol, and SSH also provides SFTP, SCP, and other functions, providing great convenience for file transmission. So I decided to install SSH on Aix.I. Required software packages Openssl.9.8.410.tar.

Basic SSH tutorial In Linux, OpenSSH is the most popular remote system logon and file transmission application, and is also a new product for traditional network applications such as Telenet, FTP, and R series. Among them, ssh (Secure Shell) can replace telnet, rlogin and rsh, scp (Secure Copy) and sftp (Secure FTP) can replace ftp. OpenSSH uses keys to encrypt data to ensure data transmission security. Bef

OpenSSH OpenSSH is a free open-source implementation of the SSH (Secure Shell) protocol. It uses secure and encrypted network connection tools instead of Telnet, FTP, rlogin, RSH, and rcp tools. OpenSSH supports SSH protocol versions 1.3, 1.5, and 2. Since OpenSSH 2.9, the default protocol is version 2, which uses the

Background information:Currently, the configuration management of the servers in the project has all migrated from puppet to Ansible, and the slow problem of SSH channels, which had previously been considered not to be troubling, is clearly exposed.Because many times need to update hundreds of servers at the same time, there are many servers and Ansible host is not the same IDC room.Accidentally found an article, referring to open SSH controlmaster and persistent socket connection, you can speed
