Description

A script to check SSL certificate expiration date of a list of sites.

The script can be launched in two modes:

• Terminal: Output is displayed in your terminal
• HTML: the script generates an HTML file (called certs_check.html by default) that can be opened with your browser.

Optionally, you can also embed the HTML and send it to an email (you will need to install mutt if you use this option)

Usage

For example, we have the following file called sitelist that contains a list of domains with the HTTPS port, one domain per line:

linux.com:443
kernel.org:443
gnu.org:443
debian.org:443
ubuntu.com:443
github.com:443
google.es:443
redhat.com:443
superuser.com:443
youtube.com:443
stackoverflow.com:443
stackexchange.com:443
wikipedia.org:443
python.org:443
codecademy.com:443
packtpub.com:443
reddit.com:443
mysql.com:443

In the following cases I modified the variables warning_days and alert_days for sample purposes.

To launch the script in terminal mode:

./sauron-eye.sh -f sitelist -o terminal

We get the following output in our terminal:

In HTML mode:

./sauron-eye.sh -f sitelist -o html

We get the following output:

In HTML mode and sending the result to an email:

./sauron-eye.sh -f sitelist -o html -m [email protected]

Checking our email we will see:

In Dockerized lauch as the following, mapping a volume with the sitelist file:

docker pull linuxshark/sauron-eye:1.0
docker run -v /PATH_TO_YOUR/SITELIST_FILE/:/app/ sauron-eye:1.0 bash /app/sauron-eye.sh -f sitelist -o terminal

If you want to get the html report with de Dockerized image, you can run the same:

docker run -v /PATH_TO_YOUR/SITELIST_FILE/:/app/ sauron-eye:1.0 bash /app/sauron-eye.sh -f sitelist -o html
