After doing a release upgrade to Ubuntu Server 18.04, Postfix stopped working with the following messages in the syslog:
Mar 11 09:56:02 servername postfix/master: warning: process /usr/lib/postfix/sbin/smtpd pid 12628 exit status 1

Here’s a quick and dirty, no-frills bash script to install the HP Server Management Tools on Ubuntu Server. As is, it will install the command line utilities to configure ILO and your RAID controllers. You can look up the other package names available for your distribution by examining the Packages file as in this example here:
Once again, we find out how worthless and pathetic Microsoft is when it comes to thoroughness. Starting with Server 2012, they added the ability to have a failover DHCP server using load balancing or by acting as a hot spare and have it replicate the server configuration, which is great, except they left out the MAC filtering lists, forcing us to use scripts yet again to accomplish something that should have been built in.

I’ve done this dozens of times now over the last couple of years when it comes to swapping out workstation hard drives with SSDs and it’s pretty much become second nature at this point, but I think the world could use a good write up on this because I’ve wasted countless hours acquiring this knowledge.
Since the internet has become overrun by a gaggle of free speech hating corporations, I thought I would take a brief moment to display my discontent for what I feel are some sort of manufacturing defects of the Logitech BCC950 conference cam.
Don’t get me wrong, for the price, this thing kicks major ass in comparison to many of the alternatives out there. The video is amazing quality for 1080@30fps with PTZ and honestly I do love the camera for all it’s strong points.
Personally I’d been fighting this Intel HD 4600 DVI/dual monitor issue for several months now, but at the time I had bigger fish to fry, so I kept putting it off until today. Those poor people on the Intel forums have been complaining about this issue for like three or four years now because “they weren’t able to reproduce the issue”, very sad. Indeed it is a very strange problem. Initially I was convinced it was strictly a driver problem, but now I think it may be some sort of weird driver/OS oddity.
If you’re unfamiliar with the issue, there are multiple threads out there on the Intel forums and several I’ve seen on the HP forums as well. The problem is that after a system reboot, the display on the DVI port is no longer detected and all you get is a black screen. The second monitor is not detected in the operating system whatsoever and the monitor shows no input signal. Right after the initial installation of the display driver, dual monitors would work, but only until the next system reboot. One workaround for this issue was to uninstall/reinstall the display driver and just never reboot the machine again, which totally sucked donkey balls.

Sure there are a few DFS-R scripts out there to choose from in various languages like batch, vbscript, and even PowerShell to name a few, but I decided to write one to fit my own personal needs at the time.
