Proxy authentication in Ubuntu 11.10 Oneiric Ocelot

UPDATE December 27th: I’ve added a post which doesn’t need dconf-editor here.

Since Ubuntu 11.10, the proxy settings tab in the system settings have been changed, it’s no longer possible to enter your credentials in the proxy settings.
There’s a solution where you can edit these settings through dconf-tools:
Download and run dconf-tools in the terminal by executing these two lines of code:

sudo apt-get install dconf-tools
dconf-editor

Within dconf-editor, goto “system > proxy” and change “mode” to manual.
Then select “use-same-proxy”
After that, go to “system > proxy > http”, enter your proxy information and select “enable”
Make sure ftp, https and socks have “0” (zero) on “port” and nothing on “Host” field
Everything should work fine now.
Update on October 23th with screenshots:

Ubuntu terminal doesn't unset proxy

Last week I’ve brought my own laptop to work and setting up evolution, subversion, the alsb and bpm environments with their proper endpoints and last but not least, I’ve set my Ubuntu Network Proxy to my companies proxy settings.
When I’ve returned home, I found out that the proxy settings were still active. One might imagine that would purge the settings in the Network Proxy to “Direct Internet Connection” but unfortunately, it did not.
Apparently there are three proxy settings which are left being set when using the terminal:

http_proxy
https_proxy
ftp_proxy

Apt-get, wget and all the CLI programs which use internet would fail because they’re searching for this proxy setting, but it isn’t to be found since we’re not at our company 🙂

A temporary solution is to unset these proxy settings, copy and paste each of these commands in your terminal and press enter:

unset http_proxy
unset https_proxy
unset ftp_proxy

I’ll add a permanent solution when I find it. For now this will clear the proxy settings within your terminal and you’ll be able to update and upgrade your repos through the terminal again!
Ps. I’m still looking for a nice dhcp client script which would add dns search domains to my /etc/resolv.conf, if you might know one; keep me posted!

Tabs are huge in Eclipse on Ubuntu

You might have noticed the tabs are a bit bigger in Eclipse than what you’re used to when running Eclipse in Windows.
(This is a minor annoyance, but more screen real estate is always welcome..!)
This is what it would look like before:

You can solve this by creating a custom gtkrc-2.0 file, which should be in your home folder.
Start up your terminal and execute the bold text:

joris@dipshit:~$ nano ~/.gtkrc-2.0

You’re in nano right now, insert the following text in .gtkrc-2.0:

style "compact-toolbar"
{
        GtkToolbar::internal-padding = 0
        xthickness = 1
        ythickness = 1
}
style "compact-button"
{
        xthickness = 0
        ythickness = 0
}
class "GtkToolbar"                              style "compact-toolbar"
widget_class "*<GtkToolbar>*<GtkButton>"        style "compact-button"

Press “CTRL+x” to close the file and press “Y” to save the edited contents.
Next time you’ll open eclipse, the tabs will look like this:
