HOWTO reconfigure timezone on ubuntu
Tuesday, September 20th, 2011MBR problem solved
Wednesday, July 27th, 2011I’ve got one machine with a totally screwed MBR.
Booted into Ubuntu LiveCD, mounted main partition. Reinstalled grub. Working. Phew.
mount /dev/sda7 /media/maverick
grub-install --root-directory=/media/maverick /dev/sda
reboot
rpm: which package provides that file?

“host not found” on nxclient connect to nxserver

And for when you’ve muffed up your grub installation, and can’t work out how to use grub-install
Minimal Ubuntu install

Q: Why can’t I open a window on another Linux machine?
Thursday, October 27th, 2005… even though the firewall is configured correctly…
A: Ubuntu/Gnome sets TCP off by default in gdm.conf. So if its a new installation, or you’ve upgraded without saving the changes you made previously, edit gdm.conf…
CoLinux for Ubuntu
Thursday, July 28th, 2005To install from scratch, follow instructions for installing Debian Sid here
Now upgrade Debian Sid to Ubuntu Hoary
- Edit /etc/apt/sources.list, comment out Debian references, insert Hoary ones
- apt-get update
- apt-get dist-upgrade
Alternatively, if you already have Ubuntu installed on a separate partition, then you can follow the the instructions for running a dual-boot CoLinux setup
Installing CoLinux on WindowsXP
Thursday, July 28th, 2005This assumes that you don’t already have a Linux installation on a dual-boot machine that you want to use, and are going to install Linux from scratch. If you do already have a working Linux setup, then you can use it. The CoLinux FAQ explains how to configure coLinux on a dual-boot machine
- Get a 2nd IP address assigned that you can use on your Windows machine for the colinux interface (assuming you’ve already got one assigned to the main interface)
- Download colinux-0.6.2.exe from sourceforge onto the Windows machine.
- Run colinux-0.6.2.exe on the Windows machine
- By default, this will install into c:\Program Files\coLinux. I prefer it to be in c:\coLinux.
- The setup program claims it needs 7.6MB for a complete install including root filesystem.
- You’ll be offered a choice of distributions – choose Debian
- Decompress the Debian filesystem. You’ll need bunzip2, I used the version from cygwin, but you can, I think, also use the Tugzip Windows program
- Edit the default.config.xml, and change root_fs to be your unzipped debian filesystem. (If you don’t do this, you’ll get “Device index not specified” when you try to start colinux.
- I also increase “memory size”.
- You should now be able to run “colinux-daemon -c default.config.xml” and get a live colinux process.
- Login as root and change the default root password from “root”
- Edit /etc/network/interfaces and /etc/resolv.conf to set the interface’s IP address, router and default nameserver.
- Halt colinux
- Setup networking. I used a bridge network between my ethernet and the TAP interface created at the time of colinux install, using the native Windows bridging. (You can also use the WinPCAP option)
- Look for new interface in Control Panel. Mine was called “Local Area Connection”, since I’d renamed the original Ethernet to “Ethernet LAN”.
- Bridge between this and the external interface
- Bring up colinux and login as root.
- Once you know it works, install it as a service.
So now you’ve got a running CoLinux installation running Debian Woody.
Now upgrade Debian Woody to Debian Sid
- Edit /etc/apt/sources.list and change stable to unstable
- apt-get update
- apt-get dist-upgrade
Printing to Windows XP printer from Ubuntu
Tuesday, May 24th, 2005Enable “Print Services for Unix” on Windows XP machine and share printer. (I’m not actually sure that this is necessary, it might be a red herring…)
When you add the printer in Ubuntu,
- Choose “Network Printer” and “Windows Printer (SMB)”
- put your Workgroup in the Host field
- Put “guest@<host>/<printer>” in the Printer field (replacing <host> and <printer> with your host & printer names)
So, for example, if your Windows machine was called “Dozer” and your printer was called “LaserPrinter”, you would put “guest@Dozer/LaserPrinter”.
You should not need a name and password for the Windows machine for this to work.
Note: please note that case-sensitivity is important.. e.g. If you think your machine name is “DOMINO”, it should be “Domino” in the config above.
