• memtest86+ crashing on server

  - by user148723

  we have a few DELL 1950 servers. 1 of this servers has CentOS6.3 and its randomly rebooting so I suspected it was hardware. (no log generated) the other 4 servers do not randomly reboot. We passed memtest86+ on the 5 servers, and on 3 of them memtest86+ crashes (displaying an odd and colorful screen, like if a video card failed) Although I tested old memtest86 (not +), and all servers did not crash. I also tested other RAM testers utilities, no tool failing. have any of you guys experience this? thanks

• What is the "real" difference between a NAS and NFS? Or, why pick a NAS device over "mere" NFS?

  - by warren

  From an end-user perspective, what is the difference between a NAS device and using NFS exports from a file server? They seem to accomplish the same end result. The difference between a SAN and other file storage is related (in my experience) to how they are connected to the server infrastructure. However, the difference between a NAS, connecting over a standard ethernet port, and NFS (sharing storage off specific servers, also over the network), seems more nebulous. Is there a good reason to pick a NAS filer over just running NFS on servers?

• Options to efficiently synchronize 1 million files with remote servers?

  - by Zilvinas

  At a company I work for we have such a thing called "playlists" which are small files ~100-300 bytes each. There's about a million of them. About 100,000 of them get changed every hour. These playlists need to be uploaded to 10 other remote servers on different continents every hour and it needs to happen quick in under 2 mins ideally. It's very important that files that are deleted on the master are also deleted on all the replicas. We currently use Linux for our infrastructure. I was thinking about trying rsync with the -W option to copy whole files without comparing contents. I haven't tried it yet but maybe people who have more experience with rsync could tell me if it's a viable option? What other options are worth considering?

• Windows 7 install crashes

  - by Alan Whitelaw

  I have a strange case that I cannot install windows 7 or windows vista on my 3 year old PC. The machine is an MSI K9NGM, with an AMD AM2 processor. I have bought a new Samsung SATA drive to install Windows 7 on, so as to preserve my existing XP install which I intend to dual boot in the future. However about half way through either a vista or w7 install (just after the mouse is shown for the first time, after the first restart) the machine will crash with a blue screen. I have removed, reordered the memory in the machine, with no luck. Does anyone have any experience of why this would happen with BOTH vista and w7 when everything is fine with XP?

• Mail.app slow to include new messages

  - by Chris Tompsett

  With Leopard I was able to link to the University's Exchange 2003 server with and IMAP connection and mail out directly vie the SMTP client. With Snow Leopard I attempted to update to a full Exchange service (Exchange 2007). Almost all has worked OK (ical, address, etc.) except that new mail posted to my email account, which is visible using a 'web' interface to Exchange remains invisible for some random number of hours. Those who are running the Exchange server have no interest in discussing the problem. Has anyone else had a similar experience?

• Nginx load distribution and multi-domain SSL

  - by Steve Clark

  I'm researching into the best methods of two new parts of our infrastructure, hopefully finding a single solution for both. 1) We're currently running a single application server, and we're going to be adding an additional application server and load balance between the two. 2) We handle a few thousand domains across the application server(s), and we're looking to support SSL. The best method i've come across so far is using nginx for it's Load Distribution to serve the requests to the application servers, and for it's SSL support. If a request is using SSL, nginx accepts the request on, terminates SSL and pipes to apache (app servers). Now, that's all good, but i'm yet to figure out how we can let nginx handle multiple domains using SSL. We're potentially looking at using UCC SSL Certs, so we can support 150 domains on a single certificate, with each cert on a single IP. I'm all new to this (My experience is just with physical load balancers and a single domains on SSL), so any advice would be very much appreciated.

• Renaming Files & Folders in Windows 7

  - by Mart

  This has been happening to me for some time now. I'm currently running Windows 7 RTM. When I try to rename a new folder that is created (by copying usually), I usually get a "Folder is in use" error. I would have to wait a while before I would be able to modify the folder name. Files behave the same way too. I am thinking that this is because I am sharing the folder, or library, via Homegroup Sharing. Is anyone who is running Windows 7 RTM experience this as well? EDIT 1: I'm using Windows 7 Ultimate.

• SQL Cluster install on Hyper V options

  - by Chris W

  I've been reading up on running a SQL Cluster in a Hyper V environment and there seems to be a couple of options: Install guest cluster on 2 VMs that are themselves part of a fail over cluster. Install SQL cluster on 2 VMs but the VMs themselves are not part of an underlying cluster. With option 1, it's little more complex as there's effectively two clusters in play but this adds some flexibility in the sense that I'm free to migrate the VMs between and physical blades in their cluster for physical maintenance without affecting the status of the SQL guest cluster that's running within them. With option 2, the set-up is a bit simpler as there's only 1 cluster in the mix but my VMs are anchored to the physical blades that they're set-up on (I'll ignore the fact I could manually move the VHDs for the purposes of this question). Are there any other factors that I should consider here when deciding which option to go for? I'm free to test out both options and probably will do but if any one has working experience of these set-ups and can offer some input that would be great.

• Set Up Remote Desktop at Home

  - by Rev

  I'm sure this has been asked before, but I'm unable to find a clear set of instructions. I'm currently using LogMeIn Hamachi to enable Windows 8's Remote Desktop feature on my home computer (running Win8 Pro x64). Unfortunatley, I can't use this method to access my home computer from my Surface Tablet, as I can't install in the Hamachi client. So how can I set up Remote Desktop without using LogMeIn Hamachi? A link to a noob-friendly tutorial would be greatly appreciated. I haven't been able to find anything that I understand (and I am pretty technical, router stuff just stumps me for some reason). EDIT: And I don't want to use a third party service like TeamViewer, in my experience those tools are laggy and quite horrible. The Remote Desktop feature has been excellent.

• Is there a free program that can detect which device on my network is causing lag?

  - by malfy

  I'm on a small business network, and rarely we experience really extreme latency. I have no idea what device might be causing the lag, and wanted to know if there was a piece of software that could detect it. I know about some softwares like wireshark, which maybe do what I'm asking? If so it's too complicated to understand. I run the program and I have no idea what I'm looking at, or what parameters to give it. So something that can monitor traffic, as well as describe it in such a way that even a not so network savvy individual can interpret.

• Should you archive documents before backing up to the cloud?

  - by gabbsmo

  I'm planning to add a cloud storage to my personal backup strategy. But now I wonder if it really is worth the trouble of compressing my documents and photos. The Open XML-format already have zip-compression and JPEG is a lossy image format. So there really isn't much benefit in compressing. 20Mb of documents become about 17Mb at the ULTRA preset of 7-zip. One benefit I can imagine is that you can shorten upload time by archiving the folders since it minimizes the number of requests that is needed to be sent to the server at upload and download. So what are your thoughts and experience in this issue? Should you archive your documents before backing them up to the cloud?

• How does Windows 7 determine that a system was not shut doen correctly (Kernel-Pwer Event ID 41)

  - by Erik

  I have a strange situation that Windows 7 thinks it was not shut down correctly, and gives me a warning in the system event log like this: http://support.microsoft.com/kb/2028504/de What the KB-article does not tell is how Windows actually determines that situation. Does it parse its own system event log after reboot? Or where does it get that information from? I am currently investigating an issue where I believe the system fails to write the system event log correctly (it stops having entries, although other logs like the application event log still have entries), and after a reboot, Windows thinks it has not been shut doen correctly. Does anybody have any experience with this? ANd can you confrim that Windows determines the previous correct system shutdown by parsing its own system event log on startup?

• Site's performance slows over time until Apache is restarted

  - by udbhav

  I'm running a Django app w/ Nginx and Apache. All our static media is stored on S3, and basically it takes a while for the app to check if thumbnails have been created every time a page is loaded. To alleviate this problem, I'm caching the output of the templates w/ memcached. Over the course of an hour or two, the site's speed goes down significantly, until I restart apache, and then all is good for a little while. I have very little sysadmin experience, and was hoping somebody could at least point me in the right direction.

• Windows File Checksums - Is my system hacked?

  - by rism

  I would like to know if there is a utility to verify the checksums of every windows file on my Win 7 Ultimate system. It seems on the surface such an obvious utility but I dont ever remember seeing one? I had a very weird experience while surfing earlier today and now Im not entirely sure my system is secure. I have a collection of tools in the WSCC suite but these tools no doubt just make system calls to the win32 api and if that has been subverted then the tools are practically useless. How do I know my Win 7 files are actually Win 7 files? I am particularly interested in verifying the integrity of all network TCP/IP files.

• What are the major distinctions between PureDarwin and FreeBSD?

  - by ??????? ???????????

  I'm looking to install a different unix on my workstation to acquire some perspective on GNU/Linux and out of curiosity. I have narrowed my options down to these two. The reason for considering PureDarwin is because I have very little experience with Apple's products. So my question is will installing and using PureDarwin give me a closer understanding of OSX than would running FreeBSD? What I have in mind are day to day routines like adding users, installing software and configuring various aspects of the underlying OS. I know that the GUI of OSX would not be available, but that is not a concern. As a secondary, less important question, can I buy OS X in the apple store and run it in a virtual machine or does that violate their EULA?

• How Lenovo x200(x61) tablet is so great for programming? whats up with so low GHz processors for deb

  - by Piddubetskyy

  for best laptop for programming after reading here looks like its Mac vs Lenovo (tablet, because tablet is only why I would choose it over Mac). I do crave that tablet but low speed processor scares me. Intel Core i5 or i7 in Sony Vaio sounds more attractive (2,26 - 3GHz for lower price). Yes, Lenovo can be fast, like x201, but with good specifications its over $2,000 its a little too much. For a lot of development I just don't want to wait every time while program compiles and builds during debugging. I want it fairly fast and smooth. Can anyone advice their experience with Lenovo's tablets?

• Firewall blocks FTP PASV response

  - by harper

  I have an FTP server that supports passive server mode (using PASV command). This works fine with Windows XP. When I want to access this server from Windows Vista or Windows 7 with firewall enabled I experience an immediate connection shutdown. A reset packet is sent to the server, and the socket is signaled that the server has reset the connection (which is not true). The problem disappears when the firewall is disabled. Connections to other FTP servers work correctly. The difference is that the server's response to PASV does not enclose the address field with parentheses. This is legal as documented in RFC-959 and RFC-1132. How can I configure the firewall to stop this bad behavior?

• NVidia raid 5 array spooling sounds and delay

  - by Chase B. Gale

  I've had a raid 5 array setup with 3 2TB WD Green drives for about 3 years now. Starting last week, when I would access the array for the first time, I hear a loud drive spooling sound and experience a ~5 second delay before being able to access\save files. This behavior happens when I don't use the array for some time (about an hour) and after occurring it doesn't happen again if I continue to access the array. I've run SMART scans on all drives and they come back as being a-ok. What's causing this? Is my array getting close to death?

• Disk controller speed responsible for slow write speeds?

  - by vizvayu

  I have question. I'm using ESXi 4.0U1 in an IBM x3200M2 with an integrated LSI 1064e RAID controller, without any kind of cache. I have 3 250GB HOT-SWAP SATA HDs configured in RAID1E (IME). ESXi works fine, read speed are quite OK, but write speeds are incredible slow, never more than 8MB/s, and this is the best case scenario, benchmarking with iozone streaming writes, using a VMWare Paravirtual controller and with only this VM active, no swapping of any kind (total vm memory reserved). Already wrote to IBM but I don't have any kind of pay support so they didn't even answered, so I'm just wondering... anybody has any experience with a similar setup? I just want to be sure this is hardware related and can't be fixed with some kind of config option, because I'm thinking on buying a new RAID controller (Adaptec 2405 looks nice). Thanks again!

• Enterprise Level Monitoring Solution

  - by Garthmeister J.

  My company is currently looking to replace our current solution used for monitoring our web-based enterprise solutions for both up-time and performance. Please note this is not intended to be a network monitoring-type solution (internally we currently use Nagios). If anyone has a provider that they have had a positive experience with, it would be much appreciated. Here is a list of our requirements: • Must have a large number of probes/agents around the globe to be representative of our customer base • Must have a flexible scripting capability to automate multi-step user actions • 24 hour a day monitoring • Flexible alerting system • Report generation capability • Mimic browser specific monitoring (optional, not a must-have)

• Which browser is the most secure? (research and practically based)

  - by wag2639

  I was wondering which browser is the most secure today, Firefox, Internet Explorer, Chrome, or Safari on a Windows machine with the user running as a Power User/Administrator account. This is not a question about which browser is the best because its the most usable, but more of a question if asked for security, which browser is the most secure given an everyday user's experience (JavaScript, Flash, Ads, etc). Also, would the choice for most secure change if the user was running as a restricted user? To clarify, I'm looking for an answer that's based in research on potential and common exploits and how long it takes for critical problems to be patched.

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• Are Virtual-Desktop Managers good or bad for system resources?

  - by jasondavis

  I am looking at Virtual-Desktop Managers for Windows 7. Right now it seems that VirtualWin is supposed to be about the best one available for use on Windows. I have never used anything like this though and I am just curious from others experience and knowledge, does something like this hog up a lot of system resources? I do not NEED it but it is a nice feature to have when I do want to use it, my PC's performance is more important then using it. So is virtual esktop managers a resource hog or probably not? Please share any tips/advice/ or comments on them, thank you =)

• Very small computer for note-taking, with full-size keyboard

  - by Reid

  I am looking for a very small, lightweight computer with a full-size keyboard for taking text notes. Ideally it would be 500g or less including batteries for 16 hours of use. And writing text is the only use - a typewriter, if I could find one light enough, would be just fine. [I realize this is not the place for product recommendations, and that's not what I'm looking for. Rather, I have no experience in this space, so what I'd like is to understand what kinds of equipment are available and what are the right keywords to plug into Google/eBay/etc. In other words, help me learn enough to do a worthwhile search.]
