If you are wanting remote access to an Ubuntu Server, the answer is SSH (Secure SHell). Ironically, SSH actually isn’t in the most secure configuration out of the box. Several of the servers I run are public facing, which means SSH particularly needs to be locked down.

So lets talk about locking down SSH. I found this article to be particularly handy:

There are two slightly more involved items on that author’s list, and there are two very easy items. I am going to deal with the very easy items because it is something everyone can do quickly and therefore should do as long as it fits their use-case.

I made the switch a few weeks ago to “ART” (Android RunTime) from Dalvik on my AT&T LG G3. All I have to say is HOLY COW… I think I have nearly doubled my battery life. I normally unplug my phone around 7:30 AM and by the time I plug it back in at night around 11:30 PM I would be down to 15% battery life. Right now it is about 1:45 AM and I am still sitting pretty at 54% battery! I am thrilled to say the least.

Ran into a fun issue today… I had a pair of Server 2012 R2 servers in a remote office that refused to sync the proper time for their clocks. No matter what I did they were always off by five minutes. One of them was a domain controller for the office.

In the process of fixing the issue I learned about an interesting feature in hyper-v that was the root cause of all my trouble. By sharing my experience, hopefully you will avoid the same issues I ran into.
