SSH is a powerful tool which often grants a lot of access to anyone using it to log into a server. In this post, I’m going to talk about a few different ways that you can easily improve the security of your SSH model without needing to deploy a new application or make any huge changes to user experience.
This article is about how pipes are implemented the Unix kernel. I was a little disappointed that a recent article titled “How do Unix pipes work?” was not about the internals, and curious enough to go digging in some old sources to try to answer the question.
he /sbin/mount.nfs helper program is provided by nfs-common. You can install it with:
sudo apt install nfs-common
sudo mount 192.168.1.5:/home/shared /mnt/common
JetBrains Mono is a new font designed especially for coders and developers. The lowercase characters are taller than the ones in other monospace fonts, improving readability.
The specific use case for a vTPM on vSphere is to support Windows 10 and 2016 security features. The HTML5 UI is designed with this in mind. Enablement of VBS does not require a vTPM.
Enablement of vTPM for any VM other than Windows 10 and 2016 is done via API. More on that in the future.
Let’s get a question I get asked about out of the way up front.
“Does this mean I can run Bitlocker on a Windows VM now?!”
Well, technically, all the parts are now there to run Bitlocker but I have to ask “Why??”. Remember, in order to enable vTPM you have to already have VM Encryption!
This means you already have a virtual machine encryption solution that’s easy to manage and works for every virtual machine that’s supported on vSphere, regardless of the guest operating system. Not to mention, you don’t have to manage the encryption “in guest” which lowers your overall workload significantly. #NoSecuritySnowflakes
If you want to test software which exploits TPM 2.0 functionality inside the qemu-kvm emulator, this can be challenging because the software stack is still quite new. Here is how I did it.
To login to the vm run: virsh console test
Please then complete the following steps:
dhclient should get an address for the vm
dnf install tpm2-tools tpm2-tss tpm2-abrmd
Then run the abrmd as root:
/usr/sbin/tpm2-abrmd --allow-root &
You should now be able to query the tpm with a command such as tpm2_pcrlist
- Edit /etc/systemd/logind.conf file:
- Find text #HandleLidSwitch=suspend
- Change suspend to ignore and remove the #
- Save file with changes

In the 1960s-1970s, Ken Thompson co-invented the UNIX operating system along with Dennis Ritchie at Bell Labs. He also worked on the language B, the operating system Plan 9, and the language Go. He and Ritchie won the Turing Award. He now works at Google. He’ll be interviewed Brian Kernighan of “K&R” fame. This talk took place May 4, 2019.

The popular screenshot tool, which uses Gtk2 and Perl, was one of the very few packages that blocked Debian (and Ubuntu) from removing the obsolete libgnome2-perl and libgnome2-vfs-perl from the repository archive. Since Shutter doesn't work without these packages, it was removed from the Debian Unstable and Ubuntu 18.10 repositories.
Since I use Shutter daily, I created a PPA for it and its dependencies...
You can use this PPA not only in Ubuntu 18.10, but also in Ubuntu 18.04 / Linux Mint 19 or 19.x, ...
I also added the gnome-web-photo package to the PPA. This package allows Shutter to take full website screenshots,...
Parameter expansion is the procedure to get the value from the referenced entity, like expanding a variable to print its value. On expansion time you can do very nasty things with the parameter or its value. These things are described here.
Aptik is a open source package that simplify backup and restore of PPAs, Applications and Packages after a fresh installation or upgradation of Debian based Ubuntu, Linux Mint and other Ubuntu derivatives.
TLP brings you the benefits of advanced power management for Linux without the need to understand every technical detail. TLP comes with a default configuration already optimized for battery life, so you may just install and forget it. Nevertheless TLP is highly customizable to fulfil your specific requirements
