apt-monitor

apt-monitor provides a web interface to easily view which Aptitude-based systems need package upgrades. It uses the asyncssh library to establish an SSH connection to a list of systems, and the Flask framework for the web interface.

Usage

apt-monitor should be provided with a list of systems to monitor, as well as an SSH key associated with each system. It can be configured to poll each system after a particular interval has elapsed.

Configuration

apt-monitor looks for apt-monitor.ini in the project root (the same folder as the src directory) by default. Here’s an example:

[apt-monitor]
interval=60

[DEFAULTS]
IdentityFile=~/.ssh/id_rsa
User=zack

[system1]

[system2]
IdentityFile=~/.ssh/id_rsa_other

Running

The project can be run from the project root with

$ FLASK_APP=src/web.py flask run

It can be stopped with Ctrl-C.

Considerations

• apt-monitor queries each system at a regular interval, and stores the list of packages that need upgraded in memory. If you are using apt-monitor for a particularly large number of systems, this could become a problem.
• This web interface should not be made publicly accesible. An attacker could use it to determine that a vulnerable package is running on your system.
