Ubuntu Linux: Tweak your network connectivity and/or performance by disabling IPV6

While browsing for a solution for Firefox’s slow connection “bug”, I found a more “global” solution in Ubuntu. In short, the global solution is to blacklist IPV6.

You can do this simply by adding the following to /etc/modprobe.d/blacklist:

blacklist ipv6

Quick Linux Shell Script Example

When I first moved to linux I had become addicted to keeping my distro updated and so I found myself typing and retyping

$ sudo aptitude update
password:
$ sudo aptitude dist-upgrade

At least once a day. Having read about shell scripts, I thought I’d try my hand at putting this into a shell script which, if you don’t already know, is linux’ more powerful answer to the Windows batch file.

So that’s what I did, and here’s how I did it.

Making the backspace key in Firefox a shortcut key to go back in Ubuntu!

Coming from Windows a few months ago, one of the things I took for granted was the backspace key being a shortcut key for the back button on my web browser - Firefox.

Once I shifted over to Ubuntu, this shortcut was missing from a default installation. If you want to replicate how the Firefox web browser on Windows has mapped the backspace key to go back a page on linux based systems, do the following:

  • Open up firefox
  • In the address bar, type about:config *this should give you a payload of preferences going down the page*
  • Once this happens, enter the word “backspace” in the filter field, this should narrow your entry to one that says browser.backspace_action.
  • Double click on the entry and change the value to 0 instead of 1.

The change should be immediate, so if you now press the [Backspace] key, it functions as a back button. I must have done this a several times when I was installing and reinstalling distributions as I messed around with my installations, but kept forgetting how to do it. :)

So this is more a quick note than any ground breaking hack.

Fixed my Feisty Fawn Wireless Mess

Well, it’s been a while since my last post, previously explained in a previous entry. I’ve managed to fix things and found out a thing or two as to why wireless support broke in feisty fawn, while still working properly in Edgy Eft.

It drove me “up the wall” (as we’d say here in colloquial Australia), but I was determined to get my system working and so I did.

Check out these posts for more information - I’ve broken it up so that you aren’t flooded with a big essay on completely different, but somewhat related subject matter:

- Linux RT818X driver crashes 2.6.20.x kernel
- How I got my Belkin f5d6001 wireless card running on Feisty Fawn

How I got my Belkin f5d6001 wireless card running on Feisty Fawn (updated)

Note: there’s been a lot of traffic to this page, and just out of interest, I’d like to know if this piece of advice has actually helped anyone out, so if it has aided you in your quest to wireless connectivity, has led you through yet another wild goose-chase, or is flawed in any manner or form, please leave a comment and I’ll make adjustments as required.

I was determined to get my wireless card up and running - There are reports out there that belkin f5d6001 cards have worked without incident for others, so I should be able to figure out WHY there are so many incidents that prevent me from running mine.

After trawlling through the internet I find out about ndiswrapper. I install ndiswrapper and as suggested use the drivers provided with my card. “belkin f5d6001″ - the driver gives you enough hope in a sense that it detects your network card, but does not detect anything else (no access points, NOTHING! but you can attempt to configure it).

After days of trying this, that and other different ways of setting up wireless configurations, I came across some post saying that you could also use rtl8180 windows drivers with ndiswrapper to make things work. I was desperate so I dug a little deeper remembering that I had reviewed the blacklist and found a bug report about Linux r818x drivers. This confirmed some things for me and so I downloaded the windows driver from realtek website.

Here are the following steps I did to make things happen:

Linux RT818X driver crashes 2.6.20.x kernel

Exasperated, exhausted and highly irritated, I hoarsely whisper a rhetorical question toward my monitors with acid dripping from my fangs:

Why does my wireless Card work on Edgy but not on Feisty?!
(oh! …and every other word was an F* word)

After doing some idle research, I found that according to a bug report in the ubuntu launchpad, the r818x linux driver that is used and works well in the 2.6.17 kernel causes kernel 2.6.20 to crash!

The Feisty Fawn Upgrade Misadventure

I’ve missed the routine weekly post as I have been trying to “unf**k” my ubuntu installations (home and work) as I colourfully put it to Neil one of my co-workers and resident IT guys. I guess this is more an apology than anything but here’s a brief rundown of what the current status is.

Ubuntu Feisty Fawn is released!

As most (K)Ubuntu fans may know, on April 19, Feisty Fawn was released and after reading many peoples reviews, I thought “awesome! I’m so there downloading the upgrade”. It was easy to upgrade from “Dapper Drake” to “Edgy eft”, then over to “kubuntu”, I thought it would be just as easy to upgrade to “Feisty Fawn”. WRONG!
