Getting the current page URI in classic ASP

This JScript gets the current URI in a classic ASP server page:

function getSv(name) { return Request.ServerVariables(name) }
var currentUri = ((getSv("HTTPS") == "off") ? "http" : "https") + "://" + getSv("SERVER_NAME") + getSv("SCRIPT_NAME")

Logging to Windows Event Log using JScript

This handy function allows you to log to the Windows Event Log using JScript, for example from a classic ASP web page:

function Log(message) {
    var shell = new ActiveXObject("WScript.Shell")
    shell.Exec('eventcreate /id 1 /l [LOG] /SO [SOURCE] /T ERROR /D "' + String(message).replace('"', '""') + '"')
}

Killing all processes that have a DLL loaded

To kill all the tasks or processes that have a DLL loaded or open, use taskkill.exe:

PS C:\> taskkill.exe /im * /t /f /fi "modules eq [YOURMODULENAME.DLL]"
SUCCESS: The process with PID 7664 (child process of PID 2572) has been terminated.

Saving the output of a windows batch file (.cmd file) to a file

Sometimes it is useful to save the output of a Windows batch file to a file as well as display it to the screen. This is a possible solution:

@echo off
setlocal
set logfile=Log.log
if not "%1" == "/nolog" (
  (
    date /t & time /t
    call %0 /nolog
  ) >> %logfile% 2>&1
  type %logfile%
  endlocal
  exit /b
) 

... your batch file starts here...

It is much easier to achieve this in a PowerShell script by using the Start-Transcript cmdlet. Tee-Object may also be handy, because it can display the output onto the screen as well as writing to a file.

NTP (time synchronisation) servers for New Zealand

The New Zealand government has two NTP servers for public use:

msltime1.irl.cri.nz
msltime2.irl.cri.nz

Bulk lossless automatic rotation of photos on Windows

Some cameras 'know' what angle the camera was being held at when the photo was taken, and this information is written to the image's EXIF data. It is possible to rotate images with this information so that they are correctly oriented.

1. Download jhead and jpegtran into the same folder (preferably on the path).
2. Run jhead -autorot *.jpg

Diagnosing slow Windows 7 boot times

To see what your machine is doing during boot up, use the tool xperfboot.exe from the Windows SDK or as a download from the Windows Performance Analysis Developer Centre.

Run this command:

xbootmgr –trace rebootCycle -resultPath %temp%\boot

This will reboot your machine twice.

xperfview can then be used to view the output:

xperfview %temp%\boot\boot_BASE+CSWITCH_1.etl

The Hamachi server has denied your login request

I ran into this problem after upgrading an older version of Hamachi:

The Hamachi server has denied your login request.

Simple Solution

This page is very popular, so I wrote an application that will reset the Hamachi configuration. The application is the simplest solution, but the steps below do the same job. Download the application here (source is on BitBucket).

You may need to restart your computer after running this program. Please let me know in the comments below whether the application fixes your problem.It looks like this program does not work on all operating systems and fix this error for all people. Your mileage may vary - feel free to contribute to the source code with your own situation.

---

The way I solved this problem was to delete the Hamachi configuration files. Procmon was able to locate the configuration folders:

• Depending on your system, one of:

  %WinDir%\System32\Config\SystemProfile\AppData\Local\LogMeIn Hamachi

  %USERPROFILE%\..\LocalService\Local Settings\Application Data\LogMeIn Hamachi

• And:

  %USERPROFILE%\Local Settings\Application Data\LogMeIn Hamachi

Below are steps you could use to clear the corrupted configuration on Windows.

1. Start an elevated command prompt. In Windows 7 and Vista, press the Windows key or click on the Start menu, then type cmd into the text field at the bottom of the Start menu. Right click on the cmd icon at the top of the Start menu and click Run as administrator - you will need to either enter an administrator password or accept the dialog that pops up next. If you do this correctly, a black window called the command prompt will pop up.
2. Copy this command line. Double click the command below to select it, and then press Ctrl+C or right click and select Copy to copy the command into the clipboard of your computer.

   cmd /c rd /s/q "%USERPROFILE%\..\LocalService\Local Settings\Application Data\LogMeIn Hamachi" & rd /s/q "%USERPROFILE%\Local Settings\Application Data\LogMeIn Hamachi" & rd /s/q "%WinDir%\System32\Config\SystemProfile\AppData\Local\LogMeIn Hamachi"

3. Run the command line. Paste the command into the black window and hit enter to run it. It should reset your Hamachi configuration files and fix the problem.

Please let me know by commenting below if this works or not for your particular situation, along with the version of Hamachi you are running if you know it.

Trinity Rescue Kit (TRK) 3.4 does not resolve DNS out of the box

If you boot the Trinity Rescue Kit (TRK) 3.4 build 367 and try to run a tool that requires the internet, such as a virus scan, you may get an error like this:

Neither DNS nor proxy parameters for wget found so no internet connection, cannot fetch AV engine

Attempting to ping google.com from a shell returns this error:

ping: unknown host google.com

The solution seems to be to launch dhcpcd from the command line:

Setting up my PXE boot server

This is basically a summary for my own records of my PXE boot configuration in case I want to rebuild it. It is quite specific to the distributions I want to access via PXE and to my configuration, so other guides will probably be more useful for readers.

Structure:

.
|-- debian
|   `-- testing
|       `-- amd64
|           |-- initrd.gz
|           `-- linux
|-- menu.c32
|-- pxelinux.0
|-- pxelinux.cfg
|   |-- default
|   `-- trinity
`-- trinity
    |-- ...lots of files...

With files sourced from:

• Debian distribution from the Debian ftp servers (the folder structure was manually created)
• menu.c32 and pxelinux.0 from Syslinux
• The trinity folder is an extraction of the iso from the Trinity Rescue Kit (TRK)
• The content of the default and trinity configuration files below

The folder structure is mounted (or directly in) /var/lib/tftpboot, and it is exported using NFS (for TRK) by the following configuration line in /etc/exports:

/var/lib/tftpboot/trinity *(ro,no_root_squash,no_subtree_check)

The folder structure is also exposed using tftpd-hpa (not tftpd) and the DHCP server is using Tomato on my router with the following configuration line in Advanced -> DHCP / DNS -> Dnsmasq custom configuration:

dhcp-boot=pxelinux.0,,192.168.1.13

There is some duplication between the two files, but I was happy enough to get them working as I wanted. If I had more time, I would look into MENU INCLUDE.

This is the configuration file called default.

Problem PXE booting Trinity Rescue Kit (TRK) 3.4

After reconfiguring my PXE boot system to boot the Trinity rescue kit, partly by following the official guide, I ran into the following error:

Looks like we 're booting from network, mounting xxxx:/yyy on /trk
/trk/trk3/trkramfs: Permission denied
Something's wrong in startup, dropping to a shell, stop booting

The solution is to modify the permissions on the file trkramfs:

chmod +rx trkramfs

I am not sure why this problem would occur in the latest build.

I was using the Trinity Rescue Kit 3.4 build 367.

Keeping track of system freezes with PowerShell

A colleague has been having some problems with her Windows 7 x64 machines freezing and requiring a forced shut-down. Unfortunately, these are not logged in the reliability monitor, but they are logged in the event log. I used PowerShell to process the event log to find start-up and shut-down events:

#Based on information from http://support.microsoft.com/kb/196452

$results = @()

function GetResult($time, $message)
{
    return New-Object psobject -Property @{ Time = $time; Message = $message };
}

Get-EventLog System | ? { $_.Source -eq "EventLog" -and 6006,6008,6009 -contains $_.EventId } | % {
    $item = $_
    switch($_.EventID)
    {
        6006 { $results += (GetResult $item.TimeGenerated "Clean shutdown") }
        6008 
        { 
            if(-not ($item.Message -match "^The previous system shutdown at (.*) on (.*) was unexpected.$"))
            {
                throw "Invalid format."
            }
            $c = ($matches[2] -replace '\u200E','') + " " + ($matches[1] -replace '\u200E','');  #not sure why, but it includes the unicode character 'LEFT-TO-RIGHT MARK'
            $dt = [datetime]::parse($c)
            $results += (GetResult $dt "Dirty shutdown")
        }
        6009 { $results += (GetResult $item.TimeGenerated "Start-up") }
    }
}

$results | sort Time -Descending

Running the script will create output similar to this:

.\ShutdownEvent.ps1

You can also filter the output, for example to only show dirty shut-down events:

.\ShutdownEvent.ps1 | ? { $_.Message -match 'Dirty.*' }

Capturing both output and error streams from a .NET process

MSDN documents a well-known problem that needs to be worked around when reading output from a console process started using System.Diagnostics.Process:

The code example avoids a deadlock condition by calling p.StandardOutput.ReadToEnd before p.WaitForExit. A deadlock condition can result if the parent process calls p.WaitForExit before p.StandardOutput.ReadToEnd and the child process writes enough text to fill the redirected stream. The parent process would wait indefinitely for the child process to exit. The child process would wait indefinitely for the parent to read from the full StandardOutput stream.

The example in MSDN is:

// Start the child process.
 Process p = new Process();
 // Redirect the output stream of the child process.
 p.StartInfo.UseShellExecute = false;
 p.StartInfo.RedirectStandardOutput = true;
 p.StartInfo.FileName = "Write500Lines.exe";
 p.Start();
 // Do not wait for the child process to exit before
 // reading to the end of its redirected stream.
 // p.WaitForExit();
 // Read the output stream first and then wait.
 string output = p.StandardOutput.ReadToEnd();
 p.WaitForExit();

The problem with this example is that it only reads from stdout - not from stderr. One solution, using the new .NET TPL (Task Parallel Library), is to launch two tasks that read the output and error streams.

ProcessStartInfo psInfo = new ProcessStartInfo
{
    Arguments = @"/c dir C:\",
    FileName = @"C:\Windows\system32\cmd.exe",
    RedirectStandardOutput = true,
    RedirectStandardError = true,
    UseShellExecute = false
};

Process proc = Process.Start(psInfo);
string stderr = null, stdin = null;
Parallel.Invoke(() => stdin = proc.StandardOutput.ReadToEnd(),
    () => stderr = proc.StandardError.ReadToEnd());
proc.WaitForExit();

There is one caveat with this approach - Parallel.Invoke does not seem to guarantee that both tasks will run in parallel. I will need to investigate this some more.

Booting into the MBR of another drive using GRUB 2

I wanted to try dual booting Linux and Windows on my machine, whose existing Windows hard drive is fully encrypted with Truecrypt. To avoid complications with Truecrypt, I put another physical disk in the machine with the intention of installing Linux on that. I wanted to be sure that the install did not touch the Truecrypt disk, including the MBR on that disk. The intention is that the new disk will become the boot disk and it will either load Linux or boot from the MBR on the Truecrypt disk.

The first trick is to make sure that the Linux installer does not overwrite the MBR on the Truecrypt disk, potentially rendering it unbootable. During the "expert install" of Debian based distros (including Ubuntu), it is important to install Grub 2 and then instruct Grub not to install to the MBR of the first hard disk. The installer will then give you the option to specify the drive whose MBR to modify - at this stage, choose the Linux disk, rather than the Trurcrypt disk.

After setting the Linux disk to be the boot disk in BIOS, edit /etc/grub.d/40_custom as the root user and add the following lines to the end:

menuentry "Other Disk" {
    set root = (hd1)
    chainloader +1
}

The key here is to set root to the Truecrypt hard drive. Do not specify a partition, because we want to boot using the MBR of the disk. Booting into grub and using ls at the grub command prompt will give you a list of all the available drives.

After modifying 40_custom, run update-grub, and reboot. You should be able to boot into Linux or into the Truecrypt drive using the Other Disk menu entry.

4. Select the index that you want to modify in the list on the left.
5. Change the value of the property Create As Clustered from Yes to No.
6. Click close, then save the table design view. 

Using the AJAX minifier as an MSBuild task to compress JavaScript

It is possible to us the AJAX Minifier to generate compact Ecmascript (JavaScript) and CSS files.

Add the following to your .csproj file within the Project tag. This page gives more detail.

<Target Name="AfterBuild">
  <ItemGroup>
    <JS Include="**\*.original.js" />
    <CSS Include="**\*.original.css" />
  </ItemGroup>
  <AjaxMin JsSourceFiles="@(JS)" JsSourceExtensionPattern="\.original.js$" JsTargetExtension=".js" 
            CssSourceFiles="@(CSS)" CssSourceExtensionPattern="\.original.css$" CssTargetExtension=".css"
            JsOutputMode="MultipleLines" JsCombineDuplicateLiterals="true"/>
</Target>

The documentation is good except that it does not detail all the options for the MSBuild task. I list them for version 4.0 below, with descriptions copied from various places including the source code and documentation:

Option	Effect	Default
JsCollapseToLiteral	Collapse new Array() to [] and new Object() to {}.	true
JsCombineDuplicateLiterals	Combine duplicate literals within function scopes to local variables.	false
JsEnsureFinalSemicolon	Appends a semi-colon to the end of the minified JavaScript.	true
JsEvalTreatment	Normally an eval statement can contain anything, including references to local variables and functions. If it is expected to do so, when the tool encounters an eval statement, that scope and all parent scopes cannot take advantage of local variable and function renaming because things could break when the eval is evaluated and the references are looked up. To reduce the amount of resulting minification but make sure that all possible references in evaluated code will hold true, use the MakeAllSafe value. However, sometimes the developer knows that he’s not referencing local variables in his eval (like when only evaluating JSON objects), and this switch can be set to Ignore to make sure you get the maximum reduction in resulting code size. Or alternatively, if the developer knows the code being evaluated will only access local variables and functions in the current scope and nowhere else, the MakeImmediateSafe value can be specified and all parent scopes will still rename their locals. Very dangerous setting; should only be used when you are certain of all possible behavior of evaluated code.	Ignore
JsIndentSize	For the multi-line output feature, how many spaces to use when indenting a block (see OutputMode).	4
JsInlineSafeStrings	Break up string literals containing </script> so inline code won't break.	true
JsLocalRenaming	Renaming of locals. There are a couple settings: KeepAll is the default and doesn’t rename variables or functions at all. CrunchAll renames everything it can. In between there is KeepLocalizationVars, which renames everything it can except for variables starting with L_. Those are left as-is so localization efforts can continue on the minified code.	CrunchAll
JsMacSafariQuirks	There are two quirks that Safari on the Mac (not the PC) needed: throw statements always seem to require a terminating semicolon; and if statements that only contains a single function declaration need to surround that function declaration with curly-braces. Basically, if you want your code to always work in Safari, set this to true. If you don’t care about Safari (for instance, in a corporate environment where the browser your users can use is highly restricted), setting this value to false might save a few bytes.	true
JsOutputMode	SingleLine minifies everything to a single line. MultipleLines breaks the minified code into multiple lines for easier reading (won’t drive you insane trying to debug a single line). The only difference between the two outputs is whitespace. (see also: IndentSize).	SingleLine
JsRemoveFunctionExpressionNames		true
JsRemoveUnneededCode	Should be set to true for maximum minification. Removes unreferenced local functions (not global functions, though), unreferenced function parameters, quotes around object literal field names that won’t be confused with reserved words, and it does some interesting things with switch statements. For instance, if the default case is empty (just a break), it removes it altogether. If there is no default case, it also removes other empty case statements. It also removes break statements after return statements (unreachable code).	true
JsStripDebugStatements	removes “debugger” statements, any calls into certain namespaces like $Debug, Debug, Web.Debug or Msn.Debug. also strips calls to the WAssert function.	true
