OpenStack and OpenDaylight with Juju+MaaS

I’m experimenting with OpenStack and OpenDaylight for 4 weeks now, and managed to crash the whole installation 4 times, when enabling OpenDaylight.

http://www.ubuntu.com/cloud/juju

It’s really frustrating having to re-setup everything over and over again, even manually, so I decided to invest more time in setup automation via JuJu and freeze some snapshots before doing any further experiments.
But even automated setups keep hanging here and there and cost a lot of time.
Plus MaaS needs to be patched each time to be able to Wake On LAN my VM’s within Virtualbox.

Real hardware would be much easier, although I need at least 8 hosts with dual network cards, that’s out of reach for me at the moment.
My wife already complains about splashing VM windows on her iMac 😀

Wrote a F5 Networks BigIP ASM Audit Tool

https://devcentral.f5.com/articles/the-big-ip-application-security-manager-part-1-what-is-the-asm

Today I spent some time to write an automatic audit tool to
crosscheck various configuration parameters within F5’s
Application Security Manager on their BigIP Loadbalancer.

In addition to daily config change diffs which are monitored in subversion, now IPv6 typos will be reported, missing iRules for certain services detected, assigned ASM policies per vServer and assigned certificates checked.

Also expiration times of SSL certificates reported, amongst a few other things.

Very useful now.
This should have been done within the box itself.
