I have been working in a new place and environment for almost 6 months now. A lot has happened since in my life and i am very excited to begin blogging again.
I gained new knowledge in many areas of Linux, servers and networking. I dealt with 6 hypervisors here, many virtual machines on them, about 20 vlans, many vpns, many pfsenses, NAS, HAS, AD, win 2012 R2 and zimbra collaboration suite.
I need to master all of this and hopefully with my basic knowledge in Linux, AD and postfix, it will be easier to grasp them.
The most important things here are the bosses and colleagues. So far they are very helpful, friendly and supportive.
I will post more about my Linux work here soon. So stay tuned but don't hold your breath. :D
