I use Autodesk Fusion 360 software for general 3D modeling work such as 3D printing, welding and other fabrication. I was trying to use Fusion 360 to design some new welding projects, primarily a new welding cart and another secret that I’ll reveal later :). However I couldn’t get the software to work today.
Today I discovered that I couldn’t make Windows 10 Pro 64-bit show me the hosts file. I wanted to make a few changes to the file for reaching some internal networks instead of memorizing IPs and found myself unable to do so. Ultimately I found a solution and it leads me to additional questions.
I just finished building a really nice Windows 10 home workstation to replace my aging and sluggish 2013 Mac Pro system. I store most of my data on CentOS 7 server with over 40TB of RAID backed storage volumes.
Today I ran a workshop with our newest network administrators; Our topic was denial of service mitigation. We currently utilize Arbor Peakflow Threat Management System to detect and scrub inbound attacks. Arbor is a phenomenal system capable of amazing performance. With the right tuning, templates and bandwidth it’s virtually handsfree. However some motivated attackers manage to
I’ve encountered this issue several times on windows VMs (sadly need a few still) where modern versions of Windows, i.e. Windows 8 will occasionally prevent you from deleting a directory.

I’ve struggled to improve Samba (SMB) performance between my Mac Pro (Late 2013) running OS X Yosemite 10.10.2 and my CentOS 6.6 Linux server. The server has a large ZFS share with all my backups and archives as well as various KVM instances running off SSDs. My Mac Pro absolutely must access that ZFS share
Working on updating some ServerTech CDU firmware today I found that they wouldn’t connect to my fresh new FTP server. I checked my firewall, I checked my server log, and saw that they weren’t authenticating correctly:
A few months ago we all saw the dramatic boom in NTP reflection attacks. These attacks exceeded DNS reflection that was so common before it. At the time I was personally experiencing consistent 10 to 40+ Gbps attacks. After a while they started to die down in frequency and volume. I still see many NTP
Hey guys, not a long post today, but thought I’d throw out an easy little tip. I was installing some KVM guests on a CentOS 6.5 storage server and needed a VNC client for my OS X desktop. Found something neat that some of you may already know, but if not, it’s pretty cool.
