On a RHEL/CentOS/RockyLinux system you can disable the UEFI secure boot from from the virt-install command. The --boot option here is the winner. The key here are the files in /usr/share/edk2/ovmf/. We will need to copy OVMF_VARS.fd from that directory to /var/lib/

Windows 11 and the new Windows Server will require a TPM (Trusted Platform Module) to be installed to run. Here is how you can emulate the TPM on a RHEL/CentOS/Rocky Linux virtualization host. Install the required packages on your virtualization host. They are swtpm (a software TPM emulator)

Intro We had a need to control windows hosts in different domains, the only hold-up? We needed to do it with a non AD-joined container. Turns out, it can totally be done. Prerequisites * The windows host has to be running winrm. * Alpine Base Image Install Required Alpine Packages apk add

Recent news indicates that the NSA has the ability to break some encryption by way of performing large computations against the pool of commonly used prime numbers used during the Diffie-Hellman key exchange. With this information it is possible to obtain the private key and therefore decrypt all communication between

After my virtualbox post I decided I would try the RHEL standard for virtualization, KVM. In this little scribble I'll be using the libvirt interface via the command line, as I don't feel that a GUI is acceptable on any server install. I will be taking

I love PuTTY, it is by FAR the most used programs on my terminal, but recent threats [http://www.symantec.com/connect/blogs/check-your-sources-trojanized-open-source-ssh-software-used-steal-information] have made me a little nervous about downloading a 64-bit version from an untrusted source. The source I trust [https://blog.splunk.net/64bit-putty/] is not

The squid proxy is an amazingly powerful web proxy that can be used from anything to captive portals, redirection, user authentication, logging, and so on; but Squid has always had a limitation where SSL was concerned. Prior to version 3.2, Squid’s method of handling SSL was to simply

I highly suggest you read his blog post as I don't feel comfortable copy/pasting some one elses hard work.

I love me some iptables and I also like having upnp running on my linux box, but the problem is my favorite linux upnp service [http://linux-igd.sourceforge.net/documentation.php] is not maintained anymore. When attempting to compile on a recent CentOS 6.5 os you are plagued with

I was having problems getting the cpuspeed daemon running after I switched to the ElRepo mainline kernel on CentOS 6.5. It turns out the newer kernel defaults to using the intel_pstate driver instead of acpi_pstate and this can cause issues with the stock cpuspeed config. If you

If you are running Dynamic DNS with DHCPd you may run into an error formatted like so: Jan 1 00:00:00 localhost dhcpd: Forward map from terminal.example.com to 192.168.100.50 FAILED: Has an address record but no DHCID, not mine. This error is a simple

I have been playing around with Virtualbox a bit recently, and from what I have experienced, I’m impressed, greatly! Granted VirtualBox in a headless environment is a little daunting at first, it is not too difficult to get use to. The biggest hurtle I experienced was getting use to

First lets define entropy for the non geeky. > “A thermodynamic quantity representing the unavailability of a system’s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.” If you’re thinking “What?” you’re not alone. Simply put, entropy

I have been playing around with Microsoft Windows 8 for a while, from its pre-release to the just leaked release to manufacturer. Every time I try to play with it I can’t stop myself from thinking how massively this is going to fail. Let me elaborate. The theory behind

SMART (Self-Monitoring, Analysis, and Reporting Technology) is a technology included in most hard drives today. You can take advantage of this technology to determine and test for hard drive failure on running systems. Almost all linux distributions systems include the smartmontools package. (I say almost because its impossible to be

Tired of having your mailbox crammed with unsolicited mail, including preapproved credit card applications? Fed up with getting telemarketing calls just as you’re sitting down to dinner? Fuming that your email inbox is chock-full of unsolicited advertising? The good news is that you can cut down on the number

After being more than frustrated with my Internet Service Provider I decided to start monitoring their service for them, and I figured that if I monitored one, I might as well as monitor all of the local ISP’s in the area. This is the result: Connectivity Monitor [http://smoothnet.

I have been playing games for a rather long time, from the days of Atari to the current time squandering titles like Call of Duty. I have been present for the birth of game genres, loved and hated titles, discovered my personal strengths and weaknesses, and I must say I’

With this law in place applicants would be able to file suit against any potential employer if they required

I ran across an interesting problem the other day, a client for some reason had mistakenly associated a particular file extension with a program, which is rather easy to do in Windows 7, causing them all kinds of problems. My client needed desperately to unassociate the file type for the
