Luckily installing XtraBackup is pretty easy $ sudo apt-key adv –keyserver keys.gnupg.net –recv-keys…
After upgrading to Natty Narwhal I couldn’t connect to my Linux based jump host (connected via VPN): OpenSSH_5.8p1 Debian-1ubuntu2, OpenSSL 0.9.8o 01 Jun 2010 debug1: Reading configuration data /home/alj/.ssh/config debug1: Applying options for * debug1: Applying options for smallpox.xxx.dk debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to smallpox.xxx.dk [xxx.xxx.xxx.xxx] port 22. debug1: Connection established. debug1: identity file /home/alj/.ssh/id_rsa type -1 debug1: identity file /home/alj/.ssh/id_rsa-cert type -1 debug1: identity file /home/alj/.ssh/id_dsa…
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 caring and used my Huwai stick instead. Recently one my colleagues noted that after upgrading to 10.10 the wireless broadband…
The performance of the site should have increased considerably – but since it meant disabling WordPress HTTPS you will probably see a warning about all elements of the page not being secured; I am working on that.
Update: This fix is now documented in the Ubuntu Wiki After upgrading to Natty alpha 2 clicking left+right mouse no longer worked as middle mouse button (also known as Emulate3Buttons). Since version 10.04 (and for real since 10.10) Ubuntu no longer sports a xorg.conf file; all configuration is done through udev and evdev – for some reason the “mouse” (track point) in my HP Elitebook 2540p is detected as a three button mouse [ …
It’s been a while since I last had to run Windows on my laptop; back then I used Ext2 Installable File System For Windows to access data on my Linux-formated partitions.
In the meantime a few things have changed: Windows 7 and Ubuntu formating ext3 with a inode size of 256 – none of these are supported by ext3 ifs.
Ext2read supports Windows 7 (as well as ext4 and LVM2) but it’s more like a file browser and does not support assigning drive letters to Linux filesystems and since my /home is formatted with XFS it does not help me anyway.
Instead of going through reformatting the filesystems I wanted to access from Windows, I decided to build a virtual file server instead; that way I can access any filesystem type supported by Linux.
Software used: Windows 7, Virtualbox and Ubuntu (server edition)
This guide will work with other versions of Windows (and other OS’es as well), there are no ties to Virtualbox and the Linux version used can be anyone you like.
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
Have yourselves a merry little Christmas – Have you ever thought about what Santa REALLY does while you’re asleep?
While my site might not be as important or visited as Google or Facebook, I decided to switch it to SSL. Some pages will show an “error” in the browser because not all content is encrypted (external images); I hope I’ll get that fixed some day.
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.
