In case you missed it, when Google releases Chrome 56, which is currently expected to be available in January 2017, the browser will not trust certificates from WoSign and StartCom issued after midnight, October 21, 2016
I’ve been using the free certs from StartCom (over Let’s Encrypt) in my homelab for UCM, Expressway, CMS, etc.. as they are not limited to the 90 day refresh but with this news it looks like I’ll be hand cranking them every 90 days again!
One of my favourite programs in Windows is the free utility from JAM Software, TreeSize free, it integrates into the Windows shell allowing you to right click on any drive or folder and display an overview of the space used and whats consuming it.
I wanted to emulate this in the Linux shell and found a few ways to do it.
du – estimate file space usage
One way to do it in Linux is to emulate it using the ‘du’ command, there are a few ways to do this but by far the best I’ve seen so far is a script written by Andrew Clarke.
I thought I’d finally sit down and learn how to Python – I wanted to do something useful with my first Python script so I decided to create an alarm notifier for the Cisco VCS. I’m aware Cisco TMS generates tickets on Cisco VCS alarms (don’t think you get email alerts?) but what if you don’t have Cisco TMS or your Cisco VCS appliance can’t be actively monitored by Cisco TMS due to your network setup?
I’ll walk you through the steps to get this working, it’s pretty simple to setup and you can just leave it to monitor your Cisco VCS appliances/VMs.
Last time I covered the TelePresence MCU backups crazyhorse made a great point that there isn’t a standard automated backup solution for the VCS configuration from Cisco, in this post I’ll walk you through setting up a simple shell script and CRON job to automate this.
