Today I'm going to write about the (in)famous iptables, the be-all do-all of GNU/linux packet filtering de-facto standard. Iptables is recognized to stand as one of the most used and most powerful firewall solutions around the web. Here I'll just share some really basic rules applied to one of my little boxes: #!/bin/bash IPTABLES=/sbin/iptables modprobe… Read More

    Who, where, what. Linux file permissions is all about numbers: read permissions correspond to a "4", write permissions correspond to a "2" and execute permissions correspond to a "1". When you sum the previous values, you'll get the corresponding "rwx"-scheme (incidentally this also happens to correspond to 3 bits - From 000 To… Read More

  In a galaxy (Windows) "Millenium" away, for hard disk drive (hdd) partitioning maintenance tasks, I used to rely on third party (alright - "stolen") applications installed on Windows. Cloning tasks where relegated to Gparted, booted off an "old" CD. Since XP-Vista, I got into "diskpart", Microsoft's "barebones" partition editor. diskpart is good for basic NTFS (doh!… Read More

Back in the day (when Shadow Copies, GitHub, SharePoint and Google Docs were unbeknown to me!), I relied on Linux file servers with Samba for basic Windows LAN company data shares. Some Company files were more important than others, so having some working copies of those files it was of utter importance (you already know… Read More

Someday I was in the process of shutting down an Hyper-V Virtual… Read More

  These days, a proper Windows file server is considered "commodity". NAS boxes are considered commodities too. Should you wish not to stick to commodities and live "off-the-grid", your LAN documents sharing needs may simply be served by a simple CentOS box (configured with Samba).   "What's the catch"?! No centralised Users management (such as when on Active… Read More

    or How-to forcefully RE-APPLY GPPs (and "do not reapply"). Someday I was playing with Group Policy Preferences (GPPs) and I noticed that my policy didn’t literally apply more than once (ie. after updating one of the policy preferences with the "new settings", that is)! To reproduce the issue, I followed these steps: 1. Created… Read More

  Someday I had a VM installed on a passthrough Hard Disk Drive. Some weekend, instead of going out, I decided I required that bloody drive to experiment "some more" ('though, a compassionate hoarder feeling inside of me didn't want to bork that OS). My solution was to migrate my Virtual Machine into a VHD… Read More

If you want to join your system to an Active Directory Domain, BUT you don't wanna lose your data & restart from scratch (ie. your Desktop, files, settings, shortcuts, you-name-it), here's how.   Gimme fuel. Before actually doing your real Local User Account to Domain User Account "profile migration", make yourself a favour — do a… Read More
