eXfat drive not working in Windows XP?

So you got a nice 64GB USB stick, and can’t format it NTFS but want to transfer huge files on it. You probably formatted it with eXfat (Windows Vista, 7, 8, Mac)

But the ISO you downloaded is on your XP machine, you can compress it and span the 4GB limit set by FAT(32) OR, you can just install eXfat support on Windows XP using the download provided by Microsoft themselves:

And, if Microsoft ever remove it, like they are prone to doing… You can download it from here:

Get MAC address from IP address

Had a routing issue the other day, and I was remotely trying to forward a port to a device. I didn’t know the MAC address of the device, and my Home Hub was insisting on that information for the forward destination. I knew the IP address, so there is a simple Windows command to get the MAC address from the IP address:

arp -a <ip_address>

I.e.

arp -a 192.168.1.70

Easy. This command works in Windows as well as Linux! Well theres a thing… It also works in Mac, but you drop the -a parameter:

arp 192.168.1.70

VPNetMon – close programs when VPN drops

If you are using a VPN to securely download files, whether it be for anomynous reasons or anything else, if the VPN connection gets dropped, your PC may revert to an unsecured connection to continue the operation.

VPNetMon is an application that montors your VPN connection and if it drops, the application can be configured to close certain apps.

So if you are using a BitTorrent client and using an anonymous VPN connection to download content this will make you feel much more secure indeed.

You can get it at http://vpnetmon.webs.com/

God, Windows is sloooooow

I am assisting a colleague today check out a rather large feature branch. I showed him the branch address and he started checking it out using Tortoise SVN on Windows 7.

Upon returning to my desk (Ubuntu 11.10), I decided to merge the branch with the major trunk. I checked out a brand new copy of the branch, merged it (for the first time in several months) and then re-committed the pages.

Guess what, he’s still checking out the original!!!

Do yourselves a favour guys, make it Linux this Christmas…

Automatic Windows Process Dump Script

I have a laborious task at the moment, of exporting our server process list to see how much memory certain programs are using. I was getting a little bored of remote accessing the server through VNC so decided to use a BAT file to do the work for me. However the problem was, I wanted to save each dump as the date it was run and this wasn’t easy in a BAT file.

C:> TASKLIST.EXE /V /FO CSV > 2011-06-14.txt

That is the function I have been using. So this is what I want the script to do.

To get the actual current date, I used this call:

ver | date > date.txt

This creates a file called date.txt and inserts the current date (with another line which I can ignore)

So, now I want to read this file into memory so I can get the date from it.

set /p var= <date.txt

This reads in the first line of the file and stores it in the var variable

The line is:

The current date is: 14/06/2011

So lets get rid of the preliminary string as we don’t want it

set var=%var:~21,10%

This sets the variable “var” to be a substring of itself, starting at character 21 and fo 10 characters. Get it?

All we need to do now is chop and change the date so I get it in the format I want, from dd/mm/yyyy to yyyy-mm-dd (I am a database sucker, so always use these format dates)

A little more confusing looking, but does the same as the previous line, picking bits of the string and putting them into the var variable.

set var=%var:~6,4%-%var:~3,2%-%var:~0,2%.txt

If you read it, you will see it takes the 4 characters starting from position 6 (this is the year), adds a “-” symbol, then 2 characters starting from the 3rd, another – and then the first 2 characters

Put it all into a batch file, and it looks like this:

@echo off
REM Chris Tate-Davies
REM Export the current process list and save as todays date.txt
REM To be run from the schheduled tasks every day

REM delete any existence of previous date
del date.txt

REM Get the date and put it in a file
ver | date > date.txt

REM open the new file and put the date in variable "var"
set /p var= <date.txt

REM chop out the string so we just have the date
set var=%var:~21,10%

REM re-allign the date parts to yyyy-mm-dd
set var=%var:~6,4%-%var:~3,2%-%var:~0,2%.txt

REM run the tasklist and pass the %var% to output to
tasklist.exe /V /FO CSV > %var%

Now all I need to do is add it to the scheduled tasks and then I can pick up the files once a week instead or stopping what I am doing every day to do it.

 

 

CSV file of Windows Process list

If you need a CSV file of the currently running  processes in Windows you can use the task manager command line tool.

C:> TASKLIST.EXE

This will dump the task list to the screen. But there are several options you can use:

C:> TASKLIST.EXE /V /FO CSV > filename.csv

The above will produce a nicely formatted CSV file with information about the process, such as CPU Time and memory used.

The full list of other options can be found at the Microsoft Technet library, well, until they move the location of it… http://technet.microsoft.com/en-us/library/bb491010.aspx
