Ubuntu

Idiot proof setup for persistent reverse shells / port forwards (same thing) under a Ubuntu VM remote and my Dreamhost server, but should apply to nearly* all *nix’s First off, some terms to keep this easy. I want to be able to access my in-office VM, xavier from my server magneto (not my names, but they conveniently complement). xavier is not publicly accessible, but magneto is. I’ll be replacing all of the FQN’s with these terms so expand on your own. In generic terms, xavier is the remote machine (i.e the one behind some NAT firewall or such that you want to get access to) and magneto is the local machine. Its a bit confusing since all of the work is done on xavier, but it makes sense in the long run. Just trust me and get on with it. ...

Ubuntu doesn’t manage vim’s addons, so installing the vim-latexsuite package doesn’t actually put all the relevant hooks into your vim installation. To do that, (after installing the package) execute; sudo vim-addons -w install latex-suite

Pre-built packages not releasing 64 bit versions? No Problem. Debian/Ubuntu based: dpkg -i --force-architecture whatever.deb RH/Fedora based: rpm -i --ignorearch whatever.rpm

Unity Sucks, and I don’t like it. I prefer a combination of Avant Window Navigator, tilda, and Gnome-Do, to go from this ** to this ** Now, I haven’t kept track of all of the changes I’ve made to my configuration files, so YMMV, but gnome-do and Avant have remarkably good GUI configuration tools, so customise to your hearts content! Get rid of Unity sudo apt-get remove unity unity-asset-pool unity-place-applications unity-place-applications ...

Ubuntu is one of those polarising technologies; Its really easy to use on a recreational basis, or as part of a institution/business wide rollout, but heartbreakingly awkward to use ‘alone’ within an entrenched business setting. One such setting is that of Queen’s University; the only form of secure remote access that is made (quietly) availiable is through a Citrix XenApp gateway. Great in theory; everyone can take a slice of a virtualized desktop, do whatever they need to do, and that processing power and memory can be easially reappropriated when they’re done. Unfortunately, in an effort to be ‘secure’, you HAVE to use Windows, and you HAVE to have Internet Explorer installed, and you HAVE to install the propitiatory XenApp client. ...

I had an incident recently where the Windows 7 side of my laptop connected easily to an open AP, but the Ubuntu 10.04 (or 9.04, tried both) wouldn’t, with the Intel Iwlagn drivers reporting in syslog a deauth (reason=6), basically the card spoke too soon. I eventually found the solution. After several weeks of asking the same question everywhere I could think of (as well as emailing Intel…) I found the answer a lot closer to home, from a PhD student ^H^H^H^H^H^H^H Graduate in my University over LinkedIn (Ironically enough, I’m actually working with him on my Final Year Project next year… Good stuff to come :D ) ...

I’ve been doing alot of messing around in Ubuntu recently and there are lots of tweaks I like to make. One of them being to show the contents of my home folder as my desktop; I don’t need any more pointless folders…. Dead easy, there is a .config directory under your $HOME dir, containing several files. The one we need is user-dirs.dirs , and it looks something like this. # This file is written by xdg-user-dirs-update # If you want to change or add directories, just edit the line you're # interested in. All local changes will be retained on the next run # Format is XDG_xxx_DIR="$HOME/yyy", where yyy is a shell-escaped # homedir-relative path, or XDG_xxx_DIR="/yyy", where /yyy is an # absolute path. No other format is supported. # XDG_DESKTOP_DIR="$HOME/Desktop" XDG_DOWNLOAD_DIR="$HOME/Downloads" XDG_TEMPLATES_DIR="$HOME/Templates" XDG_PUBLICSHARE_DIR="$HOME/Public" XDG_DOCUMENTS_DIR="$HOME/Documents" XDG_MUSIC_DIR="$HOME/Music" XDG_PICTURES_DIR="$HOME/Pictures" XDG_VIDEOS_DIR="$HOME/Videos" And this is what I changed mine to ...

Sick of having dozens of old kernels sitting under your /boot/ dir? Want a simpler boot-life? Well we’ve got the solution for you. Just one course of cleankernel once an upgrade cycle will remove all previous kernel entries from your bootloader and /boot/ dir. Basically, it lists what kernels you currently have in your /boot/ and removes them using apt .

I had a bit of a surprise logging into my weekly stats-fest that is my Google Analytics account; 300% rise in Search Based traffic. My daily traffic is meagre to say the least but still, to see such a jump on the week-on-week numbers is always a good thing. ** But I, like alot of people in this field, like knowing why! My first thought was that Google had recently sent out a press release governing updated search characteristics, and while I didn’t see anything relevant to my site in particular, its possible that general algorithmic tweaks could have slid me up the rankings. ...
