Tunneling NFS over SSH
This recipe is for tunneling NFS traffic over SSH. This adds encryption and Public Key authentication to otherwise insecure NFS traffic. For this recipe to work, requires NFSv4. Earlier versions were not tested, but I expect not all the functionality to work. server configuration ...

File system encryption in Alpine Linux
This is similar to my previous article Encrypting Filesystem in Void Linux but for Alpine Linux The point of this recipe is to create a encrypted file sytem so that when the disc is disposed, it does not need to be securely erased. This is particularly important for SSD devices ...
voidlinux virtualization
This recipe is for setting virtualization on a voidlinux desktop. Use this setup script to set things up on void linux. Connecting to libvirtd Note that virsh and virt-manager commands connect to different libvirtd sessions by defauult. virsh defaults to qemu:///session while virt-manager to qemu:///system. ...
Encrypting FileSystem in Void Linux
The point of this recipe is to create a encrypted file sytem so that when the disc is disposed, it does not need to be securely erased. This is particularly important for SSD devices since because of block remapping (for wear levelling) data can't be overwritten consistently. The idea is that the boot/root filesystem containing the encryption ...
How to encrypt linux partitions with LUKS
There are plenty of reasons why people would need to encrypt a partition. Whether they're rooted it in privacy, security, or confidentiality, setting up a basic encrypted partition on a Linux system is fairly easy. This is especially true when using LUKS, since its functionality is built directly into the kernel. Installing Cryptsetup ...
using cachefiles on an Linux NFS share
If you often mount and access a remote NFS share on your system, you will probably want to know how to improve NFS file access performance. One possibility is using file caching. In Linux, there is a caching filesystem called FS-Cache which enables file caching for network file systems such as NFS. FS-Cache is built into the Linux kernel 2.6.30 and higher. ...
Resizing a Linux RAID
It is possible to migrate the whole array to larger drives (e.g. 250 GB to 1 TB) by replacing one by one. In the end the number of devices will be the same, the data will remain intact, and you will have more space available to you. Extending an existing RAID array In order to increase the usable size of the array, you must increase ...
Raspberry Pi Weekend project
So finally took the time to try out a Raspberry Pi. For this weekend project wanted to do something relatively simple. Essentially, I wanted to recreate/enhance the functionality of a TL-WR702N. The TL-WR702N Nano Router is a neat device but being closed, can not be customized to what I wanted. It can be used in the following modes: ...
Enable local file caching for NFS share on Linux
In Linux, there is a caching filesystem called FS-Cache which enables file caching for network file systems such as NFS. FS-Cache is built into the Linux kernel 2.6.30 and higher. In order for FS-Cache to operate, it needs cache back-end which provides actual storage for caching. One such cache back-end is cachefiles. Therefore, once you set up cachefiles, it will automatically enable file caching for NFS shares. ...
Diskless Archlinux
I am still to test this recipe Server Configuration First of all, we must install the following components: A DHCP server to assign IP addresses to our diskless nodes. A TFTP server to transfer the boot image (a requirement of all PXE option roms). ...
