Building and Patching Vsftpd

0 1

In this little guide we will create a custom .deb package from vsftpd with the version information patched out. Disclaimer: Changing the version number is NOT magically saving you from everything! Security is a layered approach and is compromised of many steps - not just one! (Keep that in...

Creating a Ventoy Usb Stick

Ventoy is a fantastic way of booting many different iso’s on computers. I have used to flash usb sticks all the time with different operating systems - which in and of itself is fine… except one having many usb sticks that need to be updated and the dreaded situation in which said sticks are not...

Hosting the Arch Wiki locally

Arch Wiki Everyone knows and loves it. The one and only Arch Wiki. There is so much information encapsulated in the Wiki that having a browsable local copy can be quite beneficial. Requirements The only real requirement for hosting the Arch Wiki locally is a webserver. There are plenty of...

OPNSense Automated Config Backup

0 0

OPNSense and backups I lately searched for a way to do automated config backups which will be stored directly on my NAS. The Business Edition of OPNSense allows to do centralized backups, given the firewall in question is a managed via OPNCentral. In my homelab, this is not the case. To solve...

Set up Apache with userdir and PHP

0 0

Why? I wanted to setup a webserver on my local system with PHP enabled to do some fiddling around. The process on Debian is quite simple… so simple that you just need to install the packages and everything will already work - given you put your PHP script files under /var/www/html. But in...

The struggle I remember a time in my life where I was changing my distro literally on a weekly and sometimes on a daily basis. Oh boy, the though alone makes my head spin! Of course, I did not run any distro under the sun… but, I’ve run a fair number. From Debian based distros over RHEL to Arch...

My Linux and BSD Story

Before FOSS In the beginning there was… No, not gonna start like that. As most of you, I started with Windows back in the 90’s. Windows 98 was all the rage back then and I really did not care a lot about understanding the system I use better. Gaming, after all, was my introduction to computers...

Debian PXE

Why? Having to install Debian from time to time really made me think to doing the install over the network, rather than always making USB sticks or mounting a ISO file in a VM. The steps to set up PXE on Debian are quite easy - all in all maybe a 10 minute process. …So, let’s get to...

FreeBSD Nas

Creating a swapfile can be easily done with dd. $ sudo dd if=/dev/zero of=/swapfile bs=1M count=4k This will create a 4GB file directly under the / (root) directory. Hint: count specifies how many 1M (bs) blocks will be allocated. After the creation make sure to alter the permissions of the...
