1. Check your screen name

Open a terminal and type this command:

You’ll get a list of available screen sizes, along with the name of your screen. In my case, that’s default.

2. Run xrandr as an OpenBox startup command

Open the ~/.config/openbox/autostart file, and add this line:
xrandr --output {screen name} --mode {window size} &

xrandr --output default --mode 1280x800 &

That’s it! OpenBox will now use your desired screen resolution at startup.

I recently discovered the awesome GNU Stow application (works on unix-like systems like GNU/Linux or Mac OSX). Stow is a symlink manager, that allows you to easily deploy and remove files to or from a directory.


Let’s say you have some configuration files in your home directory (eg: .bashrc, .vimrc and a config directory .vim) and you want to have them in git to be able to track your changes and such. It’s not a really good idea to make your whole home directory a git repo. That’s where Stow comes in. Just create a configuration directory, for instance ‘dotfiles’, and create a subdirectory for every app you have configs for. Then place the appropriate files into the right subdirectory, like this:


You can now make the dotfiles directory a git repository, and keep your dotfiles safe in git. But they’re not yet in the right place, so we’ll ask our symlink manager to fix that for us.

Create symlinks

  1. cd to the dotfiles directory
  2. You can make Stow symlink the files to your homedir like so:
    stow {package}
    where you replace {package} with the name of the subdirectory you created earlier.
  3. If you now want to remove a certain package’s config files, just do this:
    stow --delete {package}

How to install Stow

On Mac OSX

Use Homebrew:
brew install stow

On GNU/Linux

Install stow using your favorite package manager, e.g.:
apt-get install stow

That’s it!


  • This procedure assumes that you’re running a debian based OS, on your local machine. It might work from MacOSX too, possibly using Homebrew to install Privoxy, and from Windows, using the .exe installer for Privoxy and a *nix-like terminal like Mingw or Git Bash.
  • The server OS needs to be unix based for this to work, and you’ll need root access over SSH.
  • We will not have to install anything on the server.

How this works

To allow the server to access the internet, we’ll tunnel the server’s internet traffic through our local computer. To do this, we’ll need to run a simple proxy on our own computer. This proxy usually listens only for local connections. We’ll then port-forward the local port to a port on the server. From the server’s point of view, it then looks as if a proxy server is available on a local port. We can then tunnel certain server’s application’s traffic through that proxy.

Setting up the proxy over SSH

Install Privoxy proxy server and run it

On your local machine
sudo apt-get install privoxy
sudo service restart privoxy

Privoxy should now be running and accepting connections from localhost only, on port 8118.

Log in to the server over ssh and port-forward the privoxy port (8118) over that connection

ssh -R 8118:localhost:8118 root@{server}
This makes the server open port 8118 for connections, which will be forwarded to port 8118 on your local machine, on which privoxy will be listening. Privoxy will then handle the request.

Forwarding traffic over the Proxy


Create or edit the /etc/apt/apt.conf file to set proxy settings for APT
On the server:
vim /etc/apt/apt.conf

Insert this line:
Acquire::http::Proxy "";

At this point, apt will work over the proxy.

The problem now is that we can’t resolve DNS requests over the proxy (We can’t use a SOCKS5 proxy because apt doesn’t work with SOCKS5 out of the box). To solve that problem we’ll edit the /etc/hosts file to contain the repository record.
On the server:
vim /etc/hosts

Insert this line (replace the x’s with the actual ip):
{xx.xx.xx.xx} archive.debian.org

If you don’t know how to get the ip address for archive.debian.org
On your local machine:
nslookup archive.debian.org

Now you should be able to use apt to update or install packages.
apt-get install git

Other programs

If you want to use the proxy for other programs on the server, like wget or git use this:
http_proxy= {command}

This way you’re setting the proxy as an environment variable, while running the command {command}. Most (well-written) command line software will use that variable, but sometimes this won’t work.

http_proxy= wget github.com

That’s it!

Whenever you need to access a server through a VPN for security reasons, you’ll most likely lose your internet connection.
If you still want or need to read your emails or browse the web for the solution of a problem, or get on IRC, it’s possible.

If there’s a server or any other computer with SSH access on your local network, it should still be reachable from your computer when it’s connected to the VPN. We’ll use that to our advantage by tunneling our web traffic through that second computer. The only problem is that DNS most likely won’t work anymore when you’re on the VPN, so we’ll have to know a login and the ip address of the second computer.

While connected to the vpn, we’ll create an ssh connection to the second computer, with some modifiers to do port-forwarding, effectively creating a SOCKS5 proxy.
ssh -C2qtnN -D 8081 {username}@{local-ip-address-of-2nd-computer}

This will not open a shell on the server, but it will make a socks5 proxy available on port 8081 (localhost).
You can now tell your browser to use that proxy as a SOCKS5 proxy, and access your mail, irc and other web needs through that connection.

If your DNS doesn’t get resolved, go to ‘about:config’ in your browser (firefox) and change
network.proxy.socks_remote_dns to boolean true

That’s it! 🙂
