• How can I migrate lab manager VM to vCloud Director

  - by jfmessier

  A friend of mine has been asked to start experimenting with migrating VMs from Vmware Lab Manager to vCloud. We know the machines/labs have to be undeployed and consolidated, which is done for this testing lab. However, what should be the next steps to make this as efficient as possible, as we have a large number of labs to migrate. Also, the dependencies tree is huge and the consolidation process is a big thing, but we know we cannot avoid this. Thanks :-)

• Monitoring VPN users on my network

  - by Fen0x

  My company runs filters on contents available for browsing and I have to check if everyone is respecting the browsing policies. Recently I have spotted some users activate OpenVPN on their workstations and i have discovered that they connect on port 443 of an external server and then use a proxy to circumvent the company filters. Is there any method to monitor VPN connections on allowed ports or to avoid the connections?

• Switches with large MAC address table?

  - by user1290200

  Does anyone know which switches have a large MAC address table ? I see most switches having only 8K, but we need to store way, way more than that (hundreds of K). I know this may seem odd, but trust me, there's no other way we can make our setup work. The only thing we seem to be able to do is install Juniper routers that store up to 1M addresses, but that will get quite costly and we'd rather avoid doing that.

Occasionally, when the drive is not plugged in, Windows appears to lose the shares, and I have to go in and share again after it's plugged in again. Does anyone have a good way to avoid losing the shares? Environment: Vista Home Premium, SP2 WD MyPassport USB-powered portable hard drive

• Special characters in Samba filenames

  - by Matti

  When serving files containing special characters such as "()?:" in the filename through Samba, the names get transformed into an unrecognizable format. For example, a file my_file:_(important).txt is displayed as M43J1E~0.TXT Is there a way to avoid this behavior (without renaming the files, obviously)? I'm assuming that character encoding is not to blame because several UTF-8 characters seem to work fine.

• Is it possible to connect an internal USB 3 card reader in a computer with only USB 2?

  - by Grzenio

  I would like to buy an internal flash card reader. There are now loads of USB 3 reader, however I still have an USB 2 system. Would it be possible to connect the new reader to the old USB port on the motherboard? I understand that I will not be able to take advantage of having the faster reader with the old motherboard, but I am planning an upgrade next year and I would like to avoid having to upgrade the card reader as well...

• Install Second Copy of Windows in a Partition, Block Access to other Partitions

  - by Mat

  I want to lend my computer to my flatmate so that he can play some games for which his computer is underpowered. Is it possible to install a second copy of Windows 7 into a separate partition and configure it such that it has no access to the other partitions and disks on the computer, the ones that I use in my main Windows install? I'm not concerned about security, just want to avoid him accidentially messing with my data somehow. Can I do that?

• Moving SQL Server databases from one drive to another?

  - by Michael Stum

  I have a SQL Server 2008 R2 on my machine which stores everything on the C: drive (C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA). I got an additional Hard Drive now and would like to move all the databases over. It's 26 databases, so I'd like to avoid manually disconnecting/reconnecting them. Ideally I would just like to move them from C: and D: and tell SQL Server to look there. Downtime is not an issue, I just don't want to do dozens of mouse clicks :)

• Convert file from VOC to MP3

  - by Thomas

  I would like to convert a sound file (from a digital voice recorder) with the extension .voc to an .mp3 file or some other common sound files. I am on Windows 7 64 bit. I have tried the program voc2wav but it gives me an error message saying that the program isn't 64 bit. The program has to be free and able to run without installing. (The voice recorder did come with a program that I could install, but I would like to avoid that).

• Idempotent Powershell word search/replace across documents with headers, change tracking, etc

  - by user61633

  I've found one or two guides to doing a word search and replace across multiple documents with powershell. They work well on simple documents. However, the script ignores text in headers and footers; and if "track changes" is enabled, it replaces text which has already been replaced, resulting in multiple copies of the new text if I run the script more than once on the same file. Any clues as to how I can avoid these undesirable behaviors and make this script robust?

• How do I cache RSS feeds in order not to miss entries on client side?

  - by Wakusei

  I'm using a client side RSS reader and turn on my PC at night. But some RSS feeds publish only a limited number of entries and old entries are removed from the feed. So sometimes I can miss entries. In order to avoid that, I want to cache feeds on some web service. Is there something like it? Although I know server side readers like Google Reader solve this problem, I still like client side readers.

• gzip compression good or bad?

  - by WarDoGG

  I have a server that currently does a lot of processing in my application and the target users are those who have a very good internet connection. The output that is sent from the server is always text/html and we do not use any media (audio/video) only images (static site images like logo,etc). We are experiencing severe performance issues and I wonder if turning off gzip/mod_deflate on the server so that the server would avoid compressing the output. Will this cause an improvement in performance?

  - by user55150

  I have a Dell GX520 optiplex model (mini tower), and I want to upgrade its RAM. I currently have 1GB RAM and I want to upgrade to 2GB.

I want to know what are the differences among them and can my PC support all those types of speeds or not? And what is the most suitable one for my Dell PC, to avoid any problems or limitations.

BTW I know on cloud Servers I may be able to add more RAM or CPU to avoid that like in Amazon EC2.

• MySQL reclaim index space after large delete?

  - by cdunn

  After performing a large delete in MySQL, I understand you need to run a NULL ALTER to reclaim disk space, is this also true for reclaiming index space? We have tables using 10G of index space and have deleted/archived large chunks of this data and unsure if we need to rebuild the table in order to decrease the size of the index. Can anyone offer any advice? We are trying to avoid rebuilding the table since it would take quite awhile and lock the table. Thanks!

  If my data looks like this: Category Sub Category 1 a b 2 c d Which shows that there are two categories: "1", which has sub categories "a" and "b", and "2", which has sub categories "c" and "d".
