Backup pfSense from Ubuntu 14.04

Back in mid 2016 Github user James Lavoy released a python script to backup pfSense. I was excited because pfSense didn’t (and still doesn’t) have a built in backup scheduler. Sure, you can backup manually from the GUI, but I don’t trust myself to remember to do that after time I make a change to my config.

I downloaded the script and changed the necessary options to point it to my pfSense box and supplied the credentials necessary for backup. I unfortunately received the following error:

AttributeError: 'module' object has no attribute '_create_unverified_context'

I quickly found out that this was due to my OS running Python 2.7.6 and SSLContext was introduced Python 2.7.9.  I reported this issue on James’ Github and he suggested installing Python 2.7.9 or later from another ppa as coding around the issue would require a complete rewrite of the script.

James has updated the README.md to indicate this requirement but his instructions are a bit out of date. The ppa specified is not being maintained and the fkrull/deadsnakes ppa should be used instead. To install python 2.7.12 and mechanize and meet all requirements of this script run the following commands:

sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python2.7 python-pip
pip install mechanize

Before running the script, make sure you edit it to point to your pfSense box’s IP address (and https port if necessary) and supply the correct credentials. Whether you are running this manually or automated you will need to specify the path for Python 2.7.9+ as it is not necessarily invoked by default by the “python” command. For example I have to run:

40 14 * * * /usr/local/lib/python2.7.12/bin/python /media/backups/pfsense-backup-master/pfsense_backup.py

In order to automate this, you’ll want to add a cron job. Do so by editing your crontab:

crontab -e

My crontab entry looks like this:

40 14 * * * /usr/local/lib/python2.7.12/bin/python /media/backups/pfsense-backup-master/pfsense_backup.py

This will run the script every day at 2:40 pm. Why 2:40? Why not?

Some may be wondering why I didn’t just upgrade my VM to Ubuntu 16.04. I tried and many services failed to load or lost their config after the upgrade, so I rolled back to a snapshot. 14.04 will continue to receive updates until 2019 as it is an “LTS” release and I anticipate migrating off the server by then anyway.

If you are like me and don’t need to be on the latest and greatest OS, but want to be able to use scripts like this, hopefully this will help.
