With the following script we monitor the SSH login on a server and send a notification via Telegram API.

This way you will get a notification in real time when someone logs in to your server via SSH. For me this is a valuable security feature.

First, we create the following Python script, which is used to send messages to Telegram’s API.

If you want to log the output of an SSH connection under macOS with pssh from Homebrew, the following error occurs:

line buffering (buffering=1) isn't supported in binary mode

In the pssh command this happens when you define the -o option for output.

pssh -t 0 -p 10 -l root -h host.list -o logs 'command'

In order to log the output of the SSH session, we have to make a small adjustment to the Python psshlib.
