• I get regular power surges and my UPS ticks a lot due to a welding plant. Is this good or bad?

  - by EApubs

  In our home, there is a mechanic who often use a welding plant. When he use it, I think we get a power surge. My UPS ticks madly (not beep, it ticks). Sometimes, I even lose power to the keyboard. When typing, some keys get missing. 1) My question is, is it good for the computer? The UPS claimed to have surge protection. But isn't it working? What should I do to protect my PC? 2) The second question is, I also have a broadband router which is not connected to the UPS. Will it be effected?

• Multiple columns in a single index versus multiple indexes

  - by Tim Coker

  The short version of my question is what's the difference between three indexes each indexing a single column and one index indexing three columns. Background follows. I'm primarily a programmer but have to do DBA work because we don't have a DBA. I'm evaluating our indexes versus the queries run against a particular table. The table as 3 columns that I'm often filtering against or getting the max value of. Most of the time the queries look like select max(col_a) from table where col_b = 'avalue' or select col_c from table where col_b = 'avalue' and col_a = 'anothervalue' All columns are independently indexed. My question is would I see any difference if I had an index that indexed col_b and col_a together since they can appear in a where clause together?

• Linux Live CD for old computer

  - by Joel Coehoorn

  I have a pentium II (that's right, pentium II) with a scant 200MB of ram. This was a high-end workstation in it's day. The machine currently runs dos on a raid array, and I need to pull some data from it. I figure my best chance at this is to use a linux live cd to copy the data to one of our active directory network shares (there is a network card in the machine). Unfortunately, my linux skills are abysmal, so I'm not sure where to get started: Where should I look to find a linux cd that will run well on such an old system Since I'm likely gonna need to be command-line only, what do I need to do to configure the network card and mount the network share via the command line? Bonus points: exact syntax needed to copy and convert the entire volume for use in VMware server 2.0, but really just copying all the data should be enough.

• Server 2003 RAS Server Utilising High WAN Traffic

  - by Joe Sergeant

  We have Routing and Remote Access configured on Server 2003 (also our primary domain controller), allowing users to connect in remotely to access files, email, etc. With one user, the RAS Server is constantly sending data to that user's remote computer. From 9am this morning it has transferred almost 800MB. The user isn't transferring any files remotely, certainly not enough to total 800MB anyway. None of the other remote users have had this issue. We have ensured that the user in question has "Use default gateway on remote network" disabled for both IPv4 and IPv6 and we are fairly confident that Offline Files isn't trying to synchronise with the server remotely, too. My question is two-fold. Firstly, has anyone had a similar experience? Secondly, what would be the best software to discover exactly what data is being sent to the remote user?

• How do you passthrough native SATA drives to a guest on ESXi?

  - by John

  I have ESXi 4.0 running on an Intel DX58S0 Mothboardboard with an Intel Core i7 930 processor. VT-d is also enabled. I have three drives in the system, drive 0 is used for ESXi. Drive 1 and 2 contain data from an older machine and show up under the "Storage Adapters" section in configuration. I would like to allow a guest machine to access the data on these drives (as nativly as possible). I have enabled passthrough of the motherboard's built in SATA controller (Intel/Marvell 88SE6121 ). This controller shows up in my guest OS, but the guest shows no drives aside from the normal virtual drive. I have tried a Linux guest and Windows7. I have also configured the host machine to try IDE/RAID/ACHI modes for the SATA controller. Any ideas how I can configure one of my guests to get at the raw data on these drives?

• How can I use fetchmail (or another email grabber) with OSX keychain for authentication?

  - by bias

  Every fetchmail tutorial I've read says putting your email account password clear-text in a config file is safe. However, I prefer security through layers (since, if my terminal is up and someone suspecting such email foolery slides over and simply types "grep -i pass ~/.*" then, oops, all my base are belong to them!). Now, with msmtp (as opposed to sendmail) I can authenticate using the OSX keychain. Is there an email 'grabber' that lets me use Keychains (specifically the OSX keychain) or at least, that lets me MD5 the password? This is a duplicate of my unanswered question on serverfault. I've put it on superuser because I'm doing this on a personal computer (viz. with OSX) so it's more of a superuser question.

• How do I remove a URL from Google without having to have a Google E-mail Account

  - by PP

  Really simple question. I do not want a Google account. I just want Google to stop making requests every 2 minutes for a URL it should never have known about (apparently Google harvests URLs from search requests as well as private e-mails, not just from actual web pages). But when I search Google help for removing URLs it appears I have to use their "webmaster tools" which require logging into a GMail account! How do I tell Google not to index my URL without becoming a customer? Note: I already return 404 for the URLs in question using a rewrite rule - this appears to make zero difference to the crawler which continually attempts to fetch the page every 2 minutes.

• Is it safe to run an operating system from an USB flash drive?

  - by Georg

  I've got a laptop that has a broken harddisk controller. Replacing the motherboard is quite expensive. I thought about buying a flash drive and installing & running the system from it. However, I'm concerned about some things. Speed: Are they fast enough for swap memory (I've got only 1GB RAM installed.) I'm considering buying 2 or 3 of them and making them into a RAID. What about limited write cycles? How long will it last for a system that has a filesystem with journaling enabled? I'd hate to abandon it. Are there significant differences between internal SSD which are used in modern laptops like MacBooks and USB flash drives? What should I expect in 10 years when the memory wear starts kicking in?

• A complete tool for auditing and archiving emails would be helpful for the community?

  - by Renato Todorov

  Please, don't treat this like a discussion question, I'm looking for direct answers: Yes / No, because... I work on a financial company and I'm needing a tool for email archiving and auditing. The compliance sector is asking for it and I have to provide it. I've searched and found two solutions: MailStore (commercial, Windows only) and Enkive (open source, very poor UI and lack of features). I'm using Postfix as MTA and Courier for IMAP/POP access. I'm almost deciding to write it myself, I have the knowledge needed, but I'm wondering right now if it's worth to put (a lot) more hours to make it open source and user friendly. So my question is, have you ever had the same need? Would this be a helpful solution? Is there any other good tool that I haven't found? Thank you!

• Decreasing lagging on router, while gaming

  - by user2699451

  I had absolutely no idea where to post this question and get a professional answer for it but here goes... Okay, so I guess everyone whos is reading this had played online, and so I was playing LoL again tonight and my brother decided that now was a great time to go on youtube and start watching a movie, so my ping (connecting from South Africa to EU west server) is around 190-220 average, however it started spiking to 2000 and average was 600-800, so it arised the question, how ther hell can I "kick" him off for the time being I tried reasoning it out with him but its like playing chess with a pigeon, he's studying to be an engineer, and I just cant win an argument with him, so i need to step it up a level... I have in the past used the aireplay method by sending deauth packets but it only helped so much, is there another way of either kicking a peer of the local wifi or decreasing the lag spikes while in session or even splitting the bandwidth equally in 2 or 3,etc What do I do p.s. sorry if off topic, if it is not appropriate, just say which website will be able to help or assist me...

• ISCSI: Ethernet cable maximum length vs. SCSI command timeout

  - by Jeremy Hajek

  I have a question about a non-optimal setup and the practical implications of this. Ideally you would place the ESXi server right in the same room as the FreeNas white box end of question. My situation is this: I have a run of ~125ft of Cat 5e connecting a ESXi server to a FreeNas whitebox in the server room. I know the distance of the ethernet cable is within the maximum distance for ethernet traffic but I have two questions... Can Cat 5e support gigbit speeds at that distance if the switch on the back end is a linksys SRW-2048? Should I be concerned about the distance causing data read and write timeouts in the SCSI portion--(disk operations of the ESXi)?

• Providing high availability and failover using MySQL on EC2

  - by crb

  I would like to have a highly-available MySQL system, with automatic failover, running on Amazon EC2 instances. The standard approach to solving this is problem Heartbeat + DRBD, but I've found a lot of posts suggesting DRBD doesn't work on EC2, though none saying exactly why. Obviously, a serial heartbeat or distinct network is out of the question in the virtualised environment. It would also be good to have the different servers be in different availability zones, but we're getting into a much harder problem there. What are peoples' opinion on having a high uptime solution in "the cloud"? Note: This question was asked before RDS with multi-AZ was announced, which is the nice automatic answer for today's modern IT professional. :)

• Cant register this user

  - by holgero

  I wanted to ask this question on meta, but it said, I have to log in first (which is where I have the problem!) I answered a question with this user. But when I tried to register and click on the stack exchange icon, it only displays three dots (animated) and never comes back. I suspected a firefox problem so I tried firefox on windows: And yes, I was able to create an account linked with my other accounts ( http://unix.stackexchange.com/users/27867/holgero and http://stackoverflow.com/users/1779245/holgero ) when I ran the latest firefox version under windows 7 in a virtual box. Then I upgraded my linux firefox to the newest version and deleted the other account under windows again. But still I cannot register this account ( http://superuser.com/users/177338/holgero ). On unix.stackexchange or stackoverflow I never had any problems with the registration, superuser seems to be different. So, how do I register this user and have it linked with my other stackexchange accounts?

• Is the Zune HD's audio card better or worse than the iPod touch's?

  - by MatthewThepc

  Firstly, if this is the wrong site to ask this question I apologize, but I didn't see one for "music players" on the stack exchange website :) After reading a few people online say that music playing from a Zune HD sounds better to them than that on an iPod touch, I was wondering whether there's any truth to that? From what I can tell, the Zune HD uses a Wolfson Microelectronics WM8352, while the first-generation iPod Touch (which the Zune HD was competing with) used a Wolfson Microelectronics WM8758BG, and newer models use the Cirrus Logic CS4398 and CS42L61. Which ones are better (to make the question less subjective, let's say in terms of quality, range, & accuracy of output)? Admittedly, I have almost no idea how everything compares and works together, but it would seem to me that, just by looking at the version numbers, the iPod has been better since it's launch. Is there anything else that effects sound quality? Thanks!

• Broadcomm WIDCOMM A2DP Quality Adjustment

  - by snicker

  So I got a sweet pair of bluetooth A2DP headphones for a sweet, sweet price (Motorola A805, if you were wondering). They sound great paired with an iPhone. However, when I pair with a computer using the latest and greatest WIDCOMM drivers, the quality is quite poor, almost un-listenable... clicking, popping, scratching. The remedy on one machine was using BlueSoleil, another bluetooth stack, as there is an adjustment for the Bitpool settings that allow you to jack the quality up. Sounds great. However, the bluetooth chipset in my other machine is not supported by BlueSoleil... so I'm stuck with the WIDCOMM stack. So the question is... Is there an undocumented way to turn up the quality for A2DP in the WIDCOMM drivers? first question on SU, usually lurking on SO.. =]

• How to make the jump from consumer support to enterprise support?

  - by Zac Cramer

  I am currently a high level consumer break/fix technician responsible for about 300-400 repairs a month. I am good at my job, but bored, and I want to move into the enterprise side of my company, dealing with Server 2008 R2 and exchange and switches and routers that cost more than I make in a month. How do I make this transition? Whats the best thing to learn first? Is there a standard trajectory for making this leap from consumer to business? I am full time employed, so going back to school is not a great option, but I have no life, so spending my nights and weekends reading and practicing is totally within my realm. I am basically overwhelmed by the number of things to learn, and looking for any advice you may have on the best way to proceed. PS - I apologize if this is a not quite the right forum for this, I know its not a technical question exactly, but I also know the sorts of people I want to answer this question are reading this website.

• What disk setup is needed / best practice for hypervisor-only servers?

  - by Luke404

  Planning to buy some servers to run an hypervisor (Citrix XenServer or VMware vSphere, still have to decide between the two) we'd like to boot off the local redundant SD card module offered by various vendors (eg. Dell, HP, etc...). The actual VMs will run from an existing iSCSI SAN (which, by the way, can't support booting the servers directly off the SAN). What are the reasons, if any, to choose completely diskless servers VS having some local storage? And what would be the guidelines to choose that local storage? (number of spindles, raid level, etc)

• Is there a way to explore my WHS files via Xbox 360's Media Center app?

  - by bangoker

  I know its a "Console" question but its really more of a Media Center Extender question! I can access the data through the Video/Pictures options, but not through the Media Center App. Also I can only see the videos that are directly on the Videos folder on my WHS, but not any of the subfolders. Same thing in my Laptop, if I connect to my WHS through Media Player it will only show the videos on Videos but not any other sub-folder, but if I open Media Center I can then connect to server and see all the folders.

• Canadian English on Apple products

  - by thepurplepixel

  Apple is an American company. As many of you probably know, Canadian English is different from American English, and closer to British English (e.g. colour instead of color). I use iWork and Microsoft Office for Mac (along with many other applications on OS X), and OS X, nor my iPhone, have an option to switch to Canadian English. Yes, you can select Canadian English as an input language in the language bar, but any program that uses the central OS X spell checking (from Mail to Office to iWork to Chrome) will check words against an American English dictionary. I know asking a question that involves an iPhone component is borderline off-topic, but I know on my iPhone I can select British English, but that turns my $ into £ and has a few other weird spelling quirks. Simple question: Is it possible to make OS X (and maybe the iPhone) use a Canadian English dictionary for its spell checking? Because British English just doesn't cut it anymore. Thanks!

• Remap key combinations in Windows

  - by nickf

  This question is similar to this one, but the accepted solution doesn't work in my case. I work on two different laptops. On one, the Home and End keys are only available by pressing Fn+Left and Fn+Right. This can make it rather annoying when switching between the two since I always go to press Fn-Right and not get what I want. The tool suggested in the other question is Sharpkeys, however it doesn't recognise Fn+Right as a different key from Right, and I suspect that registry twiddling isn't going to help me here. (?) Is there any way to remap this combination? (I'm on Windows Vista if that helps)

• Best technique for reusing a Windows system image across configurations

  - by Martin Wiboe

  We are a small company that provides solutions for ventilation systems. Part of the solution is a "controller" which communicates with the ventilation equipment. These controllers are simply Dell computers that come with our Windows 7 system image on them and sometimes some special hardware. We typically do a batch of 10 controllers at a time. We have been using Norton Ghost to apply the system image, but this process breaks because Dell changes the system configuration often, and our Windows image now does not contain the correct drivers. This is especially a problem when they change the RAID controller. To improve this, I see 2 options: use some kind of virtualization and install a hypervisor on each PC. This would solve the driver problem, but probably cause trouble with our special hardware. use some method of adding the proper drivers to our Windows image in offline mode. I haven't got much experience in either of these approaches. How would you solve our problem?

• How to configure HA iSCSI for Solaris 10

  - by Noah

  BACKGROUND: We have a StarWind NAS that we are currently using for High Availability storage with our Windows network. Starwind has mirrored drives and multiple ip paths, that the Windows Server combines into one HA disk store. QUESTION: How do I accomplish the same thing under Solaris 10? I've looked at ZFS but to document seems to indicate that ZFS wants to do its own raid/mirroring. I can also attach via iSCSI from Solaris and am presented with both drives being served by the Starwind NS. So, how do I configure solaris so that disk M1 and M2 are considered as a single fault tolerant drive?

• What is the advantage of iSCSI over SMB?

  - by sofakng

  At my house I'm running a Hyper-V server with a Windows Server 2008 R2 VM acting as a file server. Files are shared across my network using SMB. (Also, the machine is using a PERC 6/i RAID card but I don't think that's important) I'm thinking about setting up a dedicated SAN (iSCSI) machine and then switching my Hyper-V server to ESXi. What are the advantages of using iSCSI versus SMB? I think I would still need a file server OS (eg. Win 2k8) sharing files via SMB so I'm not sure the end result would be any different than my current setup...
