I recently was having a discussion with a peer around Collaboration, the Spark to Webex updates, and how it has changed overtime. A bit of reminiscence from previous versions of the Collaboration strategies and where they are going prompted me to create this entry. Lets take a look at Collaboration’s past, present, and future and assess how your organization has adopted.
With the release of OpenSSH v6.7, weaker ciphers have been disabled. Cisco CUCM has not updated the weaker ciphers used within CUCM as of v11. This causes issues with backups to the OpenSSH versions in the latest distributions. This post walks through the identification of the issue and the correction used in the CollabBackups appliance.
A touchpad on a laptop that does not turn off while typing can be quite frustrating. While configuring a new laptop, I found that this was not occurring as expected. This post walks through the process used to look at the issue and correct it.
It was time to purchase a new laptop and after much research, I decided on the Asus Zenbook. This laptop has proven to be great for me. This post covers some of my thoughts behind the purchase as well as the setup of Ubuntu on the machine.
Working with a 4k laptop has been quite nice. There are many scaling features that account for various desktops (mine is currently Unity on Ubuntu 14.04). The text within Firefox does scale within itself. While it may be cumbersome to change the setting in a separate places, there certainly are some benefits.
There are several posts out that that seemed to work for others, but I wanted to share my system configuration. The goal was to manipulate the initial login image and retain the lock screen image from the systems desktop. The dots are rather distracting too. Below is the setup I used to customized the system.
Working with an Ubuntu system that needed a system rename was quite simple, but I wanted to share a quick note here for reference.
Reclaiming disk space in VMware can be quite helpful when you are oversubscribing
lab data stores. I had a Cacti database that had grown quite large and after exporting the data, I wanted to reclaim the disk space.
Another quick tip takes us to a Linux (Ubuntu) based system that is not resolving hostnames even with DNS properly plugged in. You may even be able to successfully perform a NSLOOKUP against your domain controller. As usual, the right file update corrects the issue.
This is simply a quick reference for printing out an Ubuntu/Debian systems UID and GID.
