SSHTP is a great little Python script that will allow you to run SSH commands or transfer files on multiple hosts with a single command. It’s simple to use. You simply create a hosts file with all of the remote systems you want to execute a task on, then create a file with credentials to login and run the task. You can even configure it to be executed via a website in multiple configurations (more info on that at the bottom).
How to Install
SSHTP supports sudo, uses SSH to execute commands and SCP to transfer files, so you only need have SSH access configured on remote hosts. On the host you’re running SSHTP from, you will need Python and a few other quick-to-install packages.
- Ubuntu 16.04 LTS (The process is the same on any Debian based distribution)
- Python 2.5+ (3+ works fine also)
- Paramiko – Pythonic SSH Implementation
- pycrypto – Python Cryptography Toolkit
In addition to supporting standard username + password authentication, SSHTP also supports key based authentication. To install, login to your host via SSH and follow this guide.
First, install Python and a couple other dependencies.
sudo apt-get install python python-pip libssl-dev
Let’s go ahead and upgrade pip as Aptitude usually doesn’t install the latest version.
sudo -H pip install --upgrade pip
Now, we will use pip to install SSHTP, Paramiko, and pycrypto.
sudo -H pip install paramiko sudo -H pip install pycrypto sudo -H pip install sshpt
That’s it! You’ve installed Python, pip, and all of the dependencies needed to to run SSHPT. Next you will need to create a hosts file and authentication file based on your environmental requirements and preferences. To get more information on all available options, use the -h switch for help.
As you can see, there are many options available to customize the process to suit your needs.
user@host1:~$ sshpt -h usage: usage: sshpt [options] "[command1]" "[command2]" ... positional arguments: Commands Commands optional arguments: -h, --help show this help message and exit -v, --version show program's version number and exit -f HOSTFILE, --file HOSTFILE Location of the file containing the host list. -S, --stdin Read hosts from standard input --hosts HOSTS Specify a host list on the command line. ex)--hosts="host1:host2:host3" -k <file>, --key-file <file> Location of the private key file -K <password>, --key-pass <password> The password to be used when use the private key file). -o <file>, --outfile <file> Location of the file where the results will be saved. -a <file>, --authfile <file> Location of the file containing the credentials to be used for connections (format is "username:password"). -T <int>, --threads <int> Number of threads to spawn for simultaneous connection attempts [default: 10]. -P <port>, --port <port> The port to be used when connecting. Defaults to 22. -u <username>, --username <username> The username to be used when connecting. Defaults to the currently logged-in user. -p <password>, --password <password> The password to be used when connecting (not recommended--use an authfile unless the username and password are transient). -q, --quiet Don't print status messages to stdout (only print errors). -d <path>, --dest <path> Path where the file should be copied on the remote host (default: /tmp/). -x, --execute Execute the copied file (just like executing a given command). -r, --remove Remove (clean up) the SFTP'd file after execution. -t <seconds>, --timeout <seconds> Timeout (in seconds) before giving up on an SSH connection (default: 30) -s, --sudo Use sudo to execute the command (default: as root). -U <username>, --sudouser <username> Run the command (via sudo) as this user. -c <file>, --copy-file <file> Location of the file to copy to and optionally execute (-x) on hosts.
SSHTP is very powerful. You can easily tie it into a PHP based website to automate various commands on many different servers or workstations. For more Information on how to do that, and get other information, check the links below.
