Hmm, nobody mentioned Shrew Soft VPN Client yet ? It's a free (as in beer) and cross platform VPN client that compatible with Windows 64 bit. Although free, but support from the author has been great. Currently it doesn't support hybrid xauth+certificate mode but the feature will come soon. Lancom also provides a 64 bit VPN Client for Windows, but IMO they ...

"uname -m" is the command you're looking for. You can run both 32bit and 64bit on modern intel and AMD processors, so "uname -p" is not going to help you (in addition it mostly doesn't work these days, this here core2 thinks the response to "uname -p" is "unknown"). Looking for existence of /usr/lib64 (as has been suggested) is not going to help you either, ...

You can survive just fine with the 32 bit CentOS install. But, like the warning says, using a 32 bit OS means that MySQL can't actually use all (or even most of) the RAM installed in the system. Seems like a waste to me. If the hardware supports 64-bit, I'd certainly replace the 32 bit OS with a 64 bit one, yeah. You'd probably want to do some testing ...

Try OpenVPN (http://openvpn.net/). It's cross-platform, completely free, extremely secure, and once configured it's extremely easy to deploy. I can't confirm whether it specifically targets x64, but the x86 build should work on the x64 architecture. Edit: I should mention that OpenVPN won a "Bossie" in 2007 as the best Open Source VPN. Also, OpenVPN 2.1 ...

In order to execute an ELF binary linux needs to start a program that decodes ELF, loads dynamic libraries, etc. This program is called program interpreter. The name and full path to the program interpreter is written in the ELF itself For instance $ file /usr/bin/cheese /usr/bin/cheese: ELF 32-bit LSB executable, Intel 80386 $ readelf -l ...

I found that there isn't simple and absolute answer for questions like yours. Each virtualization solution behaves differently on specific performance tests. Also, tests like disk I/O throughput can be split in many different tests (read, write, rewrite, ...) and the results will vary from solution to solution, and from scenario to scenario. This is why it ...

Here is what I found. The 32 bit Procmon.exe contains the 64 bit exe inside it as a binary resource. When the 32 bit exe starts, it extracts the 64 bit version out to a hidden file called Procmon64.exe and then executes that. For some reason this process fails on some Windows 7 installs. I managed to extract the 64 bit exe using Visual Studio 2010. Open ...

It's not just for human readability, there are many programmatic reasons to separate 32-bit apps from 64-bit. Consider the "Common Files" folder. If you have a 32-bit app and 64-bit app that use the Common Files folder for a file with the same name, you're going to hose whichever one was installed first. There are also differences in how Windows presents ...

uname -a and look for x86_64. If you want to know if your CPU can handle 64bit, cat /proc/cpuinfo and look for lm within the flags.

Best practices: Whenever you build an AMI (or even set up an instance) always document the exact steps you took to install and configure the software and what data you put on it and where. This has many benefits including making it easy to rebuild the same AMI for a different architecture. Even better, I recommend scripting most or all of the install, ...

Maximum virtual address space of a 32 bit binary is 2^32 (4GB) - once you hit this limit, you're going nowhere. Should you switch to 64-bit? Absolutely. Not only will you no longer hit the memory barrier, the generic 64-bit instruction set has generally better performance than generic 32-bit (due to the sheer age of x86) and thus, switching to x64 will ...

You require Intel-VT or AMD-V support for your processor in order to run 64-bit Guests. If your processor supports it, it can usually be enabled through the BIOS. If you can't find the option there, chances are it may not be available. Some more reading here

Yes, there is a distinction between 64bit and 32bit regedit. There are both 32bit and 64bit keys in the registry. The default 64bit registry editor will show both of these, the 32bit one only the 32bit keys. You can only edit 64bit registry keys using the 64bit version. You can edit 32bit registry keys in either version You cannot have both versions open ...

There are security benefits when running a 64 bit version of Windows. Basically Microsoft was able to restart with more of a clean slate and implement some extra safe guards. It is partially enabled by improved hardware support in the 64 bit CPU. Here is a quick list of differences: Support for hardware based DEP. PatchGuard to prevent drivers or ...

Today Amazon released the news that they support 64-bit for m1.small instances, as well as the new m1.medium instances. Read all about it: http://aws.typepad.com/aws/2012/03/ec2-updates-new-instance-64-bit-bit-ubiquity-ssh-client.html No, the small instances are 32-bit only while the large/extra large instances are 64-bit, so you need to use ...

For a server just use the 64bit operating system Back in 2006 there were problems getting device drivers. You're talking about a Virtual Server so that certainly won't apply to you. All the software you want to run will work on the 64 bit operating system just fine The links below are the relevant sections from the Wikipedia page ...

Yes - if you use InnoDB and have read-intensive workload you can absolutely take advantage of large amounts of RAM [assuming your data set will fit in mem - your server will be blazing-blazing fast]. I'm using MySQL with InnoDB storage on 8-16 GB servers with working set fitting in memory.

On x64 platform, in Windows Task Manager, 32-bit applications will have "*32" appended to their names. So: firefox.exe *32 devenv.exe *32 svchost.exe means that both Firefox and Visual Studio are 32-bit applications, whereas Windows Services Host is a 64-bit app. On x86 platform, it's easy: 64-bit applications won't start. To reply to your last ...

VirtualBox can run 64-bit guests on a 32-bit host. You'll need to make sure your processor has hardware virtualization and that it is enabled in the BIOS. You can find some extra information at the VirtualBox Forums

Add multilib_policy=best to your /etc/yum.conf Yum will now try to install the "best" package.arch for your system and it will only install that one (as long as it is available). Assuming you're on a 64-Bit system, yum will first try to install package.x86_64, if that doesn't exist it will fall back to i386 and noarch. The default setting is ...

An easy way to see if you need more RAM is to chart the Page Life Expectancy perfmon counter. This counter tells you how long SQL Server thinks that data will be kept in the buffer pool before it needs to make room for other data. You want this number as high as possible. With 6 Gigs of RAM installed (you should have SQL set to max out at probably 4 gigs) ...

Gpo will automatically target the right system for you. A 64bit msi will not be installed on 32bit clients, but 32bit can be deployed on both 64 and 32. To avoid that 32bit msi's gets deployed to 32bit systems: Add the 32bit msi to the gpo. right click and then select properties. click the Advanced button untick Make this 32-bit X86 application available ...

cliconfig.exe is used in SQL Server 2000, the right tool to be using for SQL Server 2008 is SQL Server Configuration Manager. Nonetheless they both seem to manipulate the same registry keys. For x86: HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo For x64: HKLM:\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo To create a new ...

A 64-bit version of Internet Explorer is available for 64-bit versions of Windows Vista/7. Nobody uses it, primarily because plug-in developers cough Adobe, specifically Flash cough will not bother writing a 64-bit version of their plug-ins, and who will browse the net if YouTube doesn't work? ;) It would work fine for opening large HTML files however. ...

This post lists two different ways to check (the first is the @@version, which shows you are running a 32-bit version of SQL Server), but to save clicking through, select serverproperty('edition') The result will look something like: 32-bit: Enterprise Edition 64-bit: Developer Edition (64-bit)

After hours of research, I managed to cobble together some working instructions for Oracle 11g R2. As it turns out, you will likely need both the 32 and 64 bit clients installed to have things working in BIDS/Visual Studio/SSMS. I may have installed more Oracle components than I needed, but here's what worked for me: Download 32 and 64-bit clients from ...

Perhaps it would be worth putting some extra time and effort into researching what is causing the system to swap before spending money on memory? 32GB of memory leaves plenty of available memory even after loading the entire table, the index, and the maximum temp_table into memory. A quick search brought up these two pieces of documentation which might be ...

Most likely a licensing problem. As an example, the Standard Edition of Server 2003 64bit can use only 32GB of RAM, not for technical but licensing reasons. What Edition do you run?

I don't think there are any actual Win16 protected mode apps. I understand Windows/286 and above ran in protected mode (called "standard mode" or "enhanced mode" by Microsoft) but the apps were technically real mode apps. I remember reading that it came as a surprise to Microsoft that the Windows team figured out how to run real mode code under a protected ...
