Create e-mail with content Script ver 2 Turning Script into a Robust Automation some improved error messages, rollback step. Using script for multi system Create Commands That Affect Multiple Systems Simple Multi-SSH simple shell script that executes specified command on every machine listed in configuration file Group-Based Multi-SSH SSH review Remote connect into another PC Authentication Password Certificate Certificate authentication Generating Key Pair Specifying Authorized Keys private key alone allows to access account Generating Key Pair On client PC Ssh-keygen -t rsa -b 2048 → Generating public/private key In ~/.ssh/ Private key: id_rsa Public key: Specifying Authorized Keys Put public into authorized file (on remote PC) Cp ~/.ssh/ ~/.ssh/authorized_keys private key alone allows to access account Modify file /etc/ssh/sshd_config Change PasswordAuthentication: yes → no Simple Multi-SSH Group-Based Multi-SSH run a command on a certain subset of machines instead of being forced to run it on every machine in every circumstance Copying Files copy 1(more) local files, recursively, to a given directory on multiple PC. 1st arg (list)local file 2nd arg .
