Parsing Junos XML with Python
I’ll admit it – I’ve drunk the “Network Engineers should learn programming” Kool-Aid. In so doing, I’m gearing up for Kirk Byers upcoming “Python for Network Engineers” course by hacking a bit of Python most every evening.

Using IPv6 to Defeat Multi-tenancy Separation
I’ve always advised my clients to carefully plan the implementation of IPv6. The protocol opens new attack vectors on which ne’er-do-wells can assault your infrastructure. There are countless examples I’ve seen such as service providers locking down access to routers using IPv4 transport but leaving IPv6 transport completely open. About a year ago, I stumbled […]
