Matt Schmitz/ March 13, 2018

I have always said that I’m not sure I could write code for a living, but I do really enjoy writing scripts that make my life easier. Today’s post is a great example of that. The ease of use offered by the Juniper SRX firewalls and JunOS is something that I wish I had in all of my networking infrastructure.

SRX High CPU: httpd

Matt Schmitz/ September 5, 2017

Over the past few years of my Juniper SRX adventures, I’ve run into a few cases where the Routing Engine (RE) CPU is pegged at 100%.

Juniper SRX VPN Issues

Matt Schmitz/ April 18, 2017

Last year we began migrating from our old Juniper SSG firewalls to the new SRX line.
