Ubuntu Natty: Making a Gobi 2000 wireless modem work

In the pre-10.04 days it was possible to make a Gobi 200(0) modem work by installing gobi_loader and using it to load the firmware for the modem. However, with the release of Ubuntu 10.04 (which sports a shiny 2.6.35 kernel) gobi_loader stopped working. Because gobi_loader (according to the homepage) does not support 2.6.32+ I stopped […]

Firewall trouble

It might seem as if Nowhere.dk has been out of commission for a while. That is not the case – but a firewall configuration error (on my part) accidently blocked port 80; an error I did not see since I always use SSL. Sorry, Allan

Ubuntu 10.10 on Virtualbox

Just a quick heads-up. Virtualbox does not yet officially support Xorg 1.9 (which is shipped with Ubuntu 10.10). According to this ticket the problem will be fixed in 3.2.10. In the meantime, try you your luck which with this unsupported Additions build; it didn’t work for me though.
