Printing a remote machine's CPU information

Sometimes, we need to run a simple command on a remote machine over SSH. For example, we need to query the remote machine's CPU or RAM information. This can be done from a Python script as shown in this recipe.

Getting ready

You need to install the third-party package, Paramiko, as shown in the following command, from the source available from GitHub's repository at https://github.com/paramiko/paramiko:

$ pip install paramiko

How to do it...

We can use the paramiko module to create a remote session to a Unix machine. Then, from this session, we can read the remote machine's /proc/cpuinfo file to extract the CPU information.

Listing 6.3 gives the code for printing a remote machine's CPU information, as follows:
