How To Disable IPv6 In Ubuntu

30. April, 2012

If you’re getting errors from squid or your web browser with some weird IP address, chances are that squid is trying to connect to a server which supports IPv4 and IPv6.

To disable IPv6 on Ubuntu (also Kubuntu), add this line to the end of /etc/sysctl.conf:

net.ipv6.conf.all.disable_ipv6 = 1

Restart your computer or reload sysctl.conf by executing: sudo sysctl -p

To check, run: ip a | grep inet6

When IPv6 is disabled, this will give no output.

MercurialEclipse 1.8 With Mercurial 1.9 On Ubunutu

10. August, 2011

The MercurialEclipse plugin doesn’t play well with the latest 1.9 release of Mercurial.

If you’re on Ubuntu, you can replace the “mercurial” package with “mercurial-1.8” to get the old version back (see Launchpad packages). Thanks go to Max Bowsher for a quick solution:

sudo aptitude install mercurial-1.8

Missing Icons in Buttons (Firefox, Ubuntu Natty)

5. May, 2011

If your firefox has forgotten about all the nice icons for button in the UI (i.e. if there is a back button but it has no label or icon and all the “close tab” buttons are just tiny little invisible buttons), this bug is for you: https://bugs.launchpad.net/ubuntu/+source/ia32-libs/+bug/641056

If you start Firefox from the console, you’ll see errors like this one:

(firefox-bin:30535): Gtk-WARNING **: Error loading icon: Unable to load image-loading module: /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-png.so: /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-png.so: wrong ELF class: ELFCLASS64

Ubunutu is safer than Windows

17. June, 2010

At least according to Dell.

See point 6 (“Ubuntu is safer than Microsoft® Windows®”). Let’s see how long the page will be available.

Update 21st of June 2010: The page is still there but it now just reads “Ubuntu is secure” and instead of “The vast majority of viruses and spyware written by hackers are not designed to target and attack Linux”, it just says “According to industry reports, Ubuntu is unaffected by the vast majority of viruses and spyware” 😉
