A simple script to execute system commands through SSH on multiple hosts

SSH Commander depends on the paramiko library. No more. It runs under Python 2.7. I live in the past.

python ssh_commander.py -h

== SSH commander script ==
usage: ssh_deploy.py [-h] [-c COMMAND [COMMAND ...]] [-u] [-U]
                     [-f HOST_LIST_FILE] [--hosts ETC_HOSTS_LIST]

Command execution on multiple hosts

optional arguments:
  -h, --help            show this help message and exit
  -c COMMAND [COMMAND ...], --command COMMAND [COMMAND ...]
                        run a command
  -u, --update          update systems
  -U, --upgrade         update && upgrade systems
  -f HOST_LIST_FILE, --file HOST_LIST_FILE
                        host list file
  --hosts ETC_HOSTS_LIST
                        use /etc/hosts

• Specify the command using -c
• Use a host file list using -f
• Or your /etc/hosts file using --hosts
• You can also update or upgrade the systems using -u or -U

The host file list has the following structure:

user@IP:port password=pass id_rsa=path/to/priv_key

Only the IP is mandatory, default values for other fileds are:

• user: root
• port: 22
• pass: blank
• id_rsa: ~/.ssh/id_rsa

If no password is specified, the private key is used. An example file is included as hostlist_example.txt.
