Peace in the land of USB

Under a *nix operating system, having multiple partitions on a USB drive isn’t rocket science, it just works. ក្នុង​ករណី​របស់​ខ្ញុំ, my USB drive has two partitions because the first partition is a bootable សំខាន់​បំផុត​លីនុច installer.

I have ប្រព័ន្ធប្រតិបត្តិការ Windows on a desktop at homemostly for gamingand many of my colleagues use it too. Since Windows doesn’t do very well with non-Windows partitions I figured I could create a FAT32 partition on the memory stick after the bootable Arch Linux partition. FAT32 is almost ubiquitous and is usable on every common desktop operating system in the world.

Bleh

Unfortunately it doesn’t work straight off the bat. ជាក់​ស្តែ​ង, Microsoft in their infinite wisdom decided that memory sticks are supposed to have one (and only one) partition. In reality Windows finds the first partition and then ignores any others that happen to be set up:

Please Format

Err, no, I do not want you to format my Arch Linux installation partition

The trick to getting it working is to fool Windows into thinking the device is មិន​មាន a regular USB memory stick but perhaps a solid-state hard disk which happens to be connected via USB. Yes I know, this is seriously stupid that Windows behaves this way. A solid-state hard disk is just a whopping big (and fast) memory stick after all!

I found a few sources on how to do this however I still had to figure out some things on my own. Specifically, the guides I found either skipped some steps or didn’t provide enough information on where to download the driver package.

This procedure involves manually changing hardware drivers and installingnon-signeddriversnot intended for your hardware”. I know someone is going to break their system and blame me so I say now that I take no responsibility for any damage you may do to your Windows system as a result of this. Read that again. 😛

Instructions

remove the highlighted text

click for larger version

Download and unzip the driver, originally created by Hitachi, នៅ​ទីនេះ. Open the cfadisk.inf file in notepad (or your favourite plaintext editor), and find the section labeled [cfadisk_device]. Remove the section highlighted on the right:

Minimize (don’t close) the editor and go to your desktop iconsright-click on My Computer and select Properties. Select the hardware tab and then select [evice Manager]:

System Properties

Find the device underDisk drives”, right-click your memory stick and select Properties:

Device Manager

Click the Details tab and in the dropdown box on that page, selectHardware Ids”. Click the first line in the list of Hardware IDs and press Ctrl+C to copy the name:

USB Hardware Ids

Don’t close this dialog, go back to notepad (which was minimised) and paste the hardware ID into where the previous content was removed.

Changes pasted into notepad

Save the file in notepad and go back to the device’s property dialog window. Click theDrivertab and click the [Update Driver…] button. In the windows that pop up, selectNo, not this មិនime”; [Next] -> “Install from a list or a s បានpecific location (Advanced)”; [Next] -> “on’t search. I will choose the driver to install.”; [Next] -> [Have Disk…].

Unsigned Drivers - Click Continue Anyway

Browse to the folder where you have saved the modified cfadisk.inf file. សូមចុច [យល់ព្រម]. You will find

there is a Hitachi Microdrive driver listed. Select this and click [Next]. When the warning

appears, click [Yes]. Another warning will pop up regarding a similar issue (these are theunsigned” និង “not intended for your hardwarewarnings I mentioned earlier). សូមចុច [Continue Anyway]:

At this point I recommend closing all the dialog boxes related to the setup. Finally, remove and re-insert the memory stick into your USB port and you should find that the extra partitions on the stick are accessible. In the worst-case scenario, you might still need to partition the disk however the hard part is over. 🙂

I came across 2 bugs on Windows Server 2003 that are also relevant to Windows XP.

Short Circuits

1. Internet Explorer‘s Desktop icon is disabled. When you double-click on the icon, expecting IE to launch, it simply produces an additional shortcut. Subsequent double-clicks again produce more shortcuts. It is possible, as a workaround, to launch IE from the Start Menu.

My first guess was that malware was attempting to make me click on these new shortcuts where the new shortcuts opened further malware. This idea quickly faded though since, if malware were to have the system privileges to produce these symptoms, it wouldn’t need me to provide further privileges.

I eventually found នៅ​ទីនេះ what the actual problem was. ក្នុង​ករណី​របស់​ខ្ញុំ, the cause was related to IE6 being outdated. If a Windows registry entry is namedLegacyDisableand is added to specific types of registry keys, it lets Windows know that the key is obsolete and that it has only been left behind for backwards-compatibility. In this case, it disabled the intended primaryverbfunction (the double-click) of the shortcut: launching IE.

To fix, you can either update to the latest version of IE or fix the registry entry directly. If you experience this issue even with the latest version of IE then the registry value is the only way I know how to fix it.

Danger, Will Robinson!

Though this is a trivial registry change, the registry is still a dangerous thing to mess with so, as usual, back up your registry: See KB322756. Nobody gets to blame me for trashing their system. 😛

De-Register me!

Paste the following into a .reg file and execute it; or manually remove theLegacyDisableentries referred-to here:

[HKEY_CLASSES_ROOT\CLSID\{871C5380-42A0-1069-A2EA-08002B30309D}\shell\NoAddons\]
"LegacyDisable"=-
 
[HKEY_CLASSES_ROOT\CLSID\{871C5380-42A0-1069-A2EA-08002B30309D}\shell\OpenHomePage]
"LegacyDisable"=-

Fire me up!

2. When trying to browse to any site from within IE, IE remains dormant while របស់ Firefox is launched. Firefox then loads the page which was originally requested in IE.

While many might most of the time consider this to be a triumph [insert childish laughter here], the site I wanted to browse to was the Windows Updates site which, unfortunately, does not work when using Firefox. The same would apply to other sites which depend on the web browser supporting ActiveX.

De-Register Me Too!

I eventually found the solution នៅ​ទីនេះ, and it turns out to be similar to the solution for the first bugexcept that it is to remove an entire key. ជា​ថ្មី​ម្តង​ទៀត, ensure you have a backup of your registry before continuing. Here is the relevant content of the .reg file:

[-HKEY_CLASSES_ROOT\CLSID\{C90250F3-4D7D-4991-9B69-A5C5BC1C2AE6}]

I hope that resolves things for anyone else having similar issues. 🙂

[កែសម្រួល] So much for that. It turns out that openssl is able to determine that the key and certificate are already in a single file. Therefore, no csplitting required (ល្អ, I hope somebody reading this at least learned about how nice csplit is). In fact, the whole script might as well be obsoleteblaargh. Well, at least it gives a nice warning about not giving a blank passphrase. 😀

Here’s the new version:

pem2pfxconverts a .pem-formatted file containing a private key and signed certificate into a Windows-compatible .pfx certificate file.

#!/bin/bash
#pem2pfx
#v0.2
#យ៉ាង​ដូចម្តេច - brendan@swiចtspirit.co.za
# Converts a .pem certificate file to .pfx format
# $1 is the source file
set -e
 
if [ $# = 1 ]; then
  outputfile=`echo $1 | sed 's/.pem$/.pfx/'`
 
  echo "Please specify a password below. ប្រព័ន្ធប្រតិបត្តិការ Windows បានបដិសេធក្នុងការនាំចូលវិញ្ញាបនបត្រ .pfx ដោយមានពាក្យសម្ងាត់ទទេមួយ។"

I’m very happy to report that 2 much-needed and related features I’d filed bugs for at KDE’s Bug Tracking System bugzilla were added to KDE & ‧​; 4.2‘s KRDC. KDE & ‧​; 4.2 was just released and is now available within kdemod (aka Chakra)’s repositories. KDE-loving *nix-loving Windows administrators rejoice!

  • Ability to specify a default Username: Previously, before logging in, you’d be prompted for the username. Now the prompt is automatically filled in with a default username.
  • Ability to recognise LDAP logins and remember the password using kwallet as an LDAP Login.
KRDC options added

New KRDC options added

A very big thank you to the developer maintaining KRDC, Urs Wolfer.
