• Any problems with using a 301 redirect to force https traffic in IIS?

  - by Jess

  Is there any problem with using a 301 redirect to force all traffic to go to a secure-only site? We originally had redirect rules, but enforcing SSL-only seemed more secure. Here is how we set it up: Site 1: https://example.com/ Require SSL set Bound to 443 only Site 2: http://example.com Bound to 80 only Empty folder - no actual html or other data 301 Redirects to https://example.com This seems to work beautifully, but are there any issues with doing this? Would any browsers not recognize the 301 redirect, or could there be security warnings during the redirect?

• Website filtering for OpenVPN clients

  - by Asche

  I am currently trying to block some websites by their domain names for all the clients of my OpenVPN server. My first idea was to use the /etc/hosts file. But, its effects seem to be limited to the host only and not to be taken in consideration by OpenVPN. I then tried to configure bind9 and to interface it with OpenVPN, but that solution was unsuccessful and uneasy to use. After this, I considered using iptables to drop all the packets from/to those websites but that forum thread made me thought otherwise since iptables' behavior with FQDN may generate complex issues. Have you got a solution to block websites for all clients using an OpenVPN server on which I am root?

• What version of Ubuntu to use for Desktop with 8Gb RAM?

  - by Alexander

  This may sound as a stupid question, but I am really interested whether Ubuntu Desktop i386 will be able to use all my available RAM. I want to use the latest, non-LTS version, 10.10. It says on the website that it's (i386) the Recommended version. I also recall that Flash Player had issues with 64 bit Linux. Also, the 64 bit version is listed in the Universal USB Installer as amd64. Does this mean that it's using instruction sets specific to AMD CPUs? (I have an Intel) Will it work fine with Intel? So which one to download and install? What to do to be able to use 8Gb of RAM?

• Motherboard warning lights when plugging in a display port cord to graphics card?

  - by rllr

  Earlier today, my computer spontaneously shut itself off and refused to turn back on. I tested my PSU and it's operating fine. I unplugged everything and let it sit for a while and it started to make a high pitched coil whine/hiss. When I came back an hour later and plugged in only the power cord, it turned on without any issues. After some troubleshooting, I noticed my motherboard (Intel D975XBX2) has a red CPU led and VR led that come on whenever I plug my monitor into my graphics card via display port. DVI does not cause a similar issue. I was running three monitors off the card, so I need both DVI ports and the display port working. Is it likely my graphics card needs to be replaced, or should I be looking elsewhere to resolve this issue?

• Need hard disk recommendation for linux home server.

  - by neotracker

  Hello, I'm planing to build a little linux homeserver. It will mainly be used for storage and maybe as an media pc. I plan to build a software raid5 with 4 1.5TB or 2TB hard drives. I already decided to use the Western Digital Caviar Green 1.5 TB drive, but then I read about some problems with the WD green series about many drives failing and that they are not recommended for raid anyway. Of course, I couldn't find much facts on the issues so I thought I just ask here ;-) What hard drives would you recommended for a software raid5 setup? As I only need it for storage, the whole thing doesn't have to be too fast. So I prefer a cheap price and silence to great performance.

• MacBook repeatedly disconnects from Wi-Fi

  - by redwall_hp

  I have an early 2008-model MacBook (2.4 GHz). The Wi-Fi router I have at home is a Linksys WRT54GX2 that I have had for a few years. My MacBook has recently started disconnecting from the router every few minutes, which is rather annoying. I can reconnect again without having to restart the router or anything, as it seems that the MacBook is just dropping the connection. I have tried changing the channel on the router, and upgrading the laptop from Leopard to Snow Leopard made no difference either. I'm only about six feet from the Linksys device, so distance isn't an issue. This only happens with the Linksys router, while I can use the local library's open network without any issues. The problem also seemingly becomes more pronounced after midnight. What could the problem be? Edit: Here are the logs that Spiff requested: http://pastie.org/951761

• cygwin rsync over ssh very slow

  - by Waleed Hamra

  I have 2 machines running Windows Xp SP3. I have cygwin installed on both, version 1.7. I have rsync and ssh installed on both, and configured using default settings as per ssh-host-config and ssh-user-config programs provided. I moved the public keys into their respective locations, and basically ssh is working fine. i began an rsync operation, using: rsync -av --delete --hard-links local_dir username@other_machine:/some_dir well... on both machines, the processor is running near idle, no heavy usage. I checked IO using process explorer on both machines, and that too is at normal levels (1~2 MB/s), so I can't see where the bottlenecks are, because network performance is aweful. I'm not going over 1MB/s... when a normal file copy using windows sharing achieves some ~10 MB/s.. What could be wrong?

• Problem opening password encrypted .docx file on Word 2003

  - by molecule

  Hi all, I am having a problem opening a .docx file on my Word 2003. I have installed the Compatibility pack for 2007 but when i try to open this particular file, I receive the error "Word experienced an error trying to open the file. Try these suggestions. 1. Check the file permissions for the document, 2. Make sure there is sufficient free memory and disk space, 3. Open the file with the Text Recovery converter. I do not think it is any of the errors as I am able to open it on a different PC with Word 2003 as well. I also do not have any issues opening any non-password encrypted .docx files. Has anyone experienced the same issue? Most posts on the internet relate to "open and repair" but as mentioned, I am able to open this file on another PC without any problems. Any advice is greatly appreciated. Thanks, George

• How does Windows handle Time? Updating RTC, etc. (Active Directory and Novell E-Directory)

  - by bshacklett

  I'm troubleshooting some time issues in my domain and before making any big changes I want to have a thorough understanding of what's going on. I've got a few lingering questions at the moment: What sources (rtc, ntp, etc.) are queried by Windows to keep time? How does this differ in a mixed Active Directory / Novell environment? What is the order that each source is queried in? How does Windows decide whether to act as an NTP client, peer or server? In what situations will Windows update the RTC, if ever?

• How do I find the source of soft page faults?

  - by David Robison

  I have Windows 7 x64 computer that according to Performance Monitor has 70,000 page faults / second when idling. That's seems like a lot to me (every other computer I check has basically 0 page faults / second when idling). If I use Resource Monitor or Process Explorer to check hard faults, I see that they are basically 0. So all the page faults are soft. Normally, soft page faults are not a problem, but I suspect they might be causing issues for this computer given there are so many. I would like to identify what programs are causing the soft faults. Are there any tools that exist the display the number of soft page faults for each process?

• File sometimes doesn't download from my website

  - by kylex

  When I attempt to download this file, sometimes it only downloads about 700KB (the file is 40MB) then I get the message that the download is complete. If I try to download the file again, it works properly. The problem seems prevalent in IE, although I've had it happen in Chrome sometimes too. I have the following code: <input type="button" value="Agree to Terms and Download" onClick="location.href='/downloads/setup.exe';" /> If it matters, this is over a secure connection. I also tried zipping the file, and had the same issues.

• Missing 16:10 resolutions with Nvidia drivers (Can't add resolutions)

  - by Wuinny

  Hello, I have a laptop with a Nvidia 9650M GT and used the drivers that Seven brought me. It works fine but Metro 2033 tells me that i have to upgrade my drivers to play the game. So i did it. But since i did a clean install of the new Nvidia drivers, i just have 1440*900 or 4:3 resolutions. I usually played with 1280*800 or 1184*740 (for performance issue) With the "old" drivers i was able to create custom resolution (1184*740) in Nvidia control panel but now when i try it tells me that "my monitor cannot support this resolution". When i insist, it works but soon as i shut down my computer i have to recreate it.. Do anyone have a fix ? Thank you

• Using MongoDB + Redis + Apache on the same server in production?

  - by Dayson

  I intend to launch my web app using a 8 GB VPS. It uses MongoDB + Redis for storage/caching and Apache + PHP-FPM for serving requests. Could there be any issues with running Mongo + Redis + Apache on the same server? Would it make more sense to setup 2 x 4 GB VPS servers and keep Mongo on one and Redis + Apache on another? Should I just start with one server and worry about scaling horizontally later by delegating the existing server to Mongo in the future (due to its large RAM) and moving the web servers on to multiple smaller VPS'?

• Out Of Memory Error - Magento

  - by robobobobo

  Ok normally I understand when my server is giving me out of memory errors, but this one has me stumped! I'm running a magento based site, with one or two plugins in it and the rest is pretty basic. The site runs and loads fine wiht no issues. However in the backend - Configuration - Payment Methods it gives me the following out of memory error Fatal error: Out of memory (allocated 39059456) (tried to allocate 85 bytes) in ########/Varien/Simplexml/Element.php on line 84 Now this is where I'm confused..it's allocated more than it tried to allocate? Am I correct there? So how is it running out of memory? My server has 6Gb ram, an SSD and 2 CPU's running WHM with a few other low traffic sites on it. I set my php memory limit to 100mb, 1000mb and finally unlimited but all to no avail! I'm completely lost here, would really appreciate some expertise on this Cheers

• Corrupt mysql system tables

  - by psynnott

  I am having issues with the columns_priv table in the mysql system database. I cannot add new users currently. I have tried repairing it using mysqlcheck --auto-repair --all-databases --password but I get the following output: mysql.columns_priv Error : Incorrect file format 'columns_priv' error : Corrupt Is there any other way to repair this table, or how do I go about replacing it with a blank table? What would I lose by doing that? Thank you Edit (Additional Info) mysqld is currently using 100% cpu constantly. Looking at show processlist, I get: mysql> show processlist; +-----+------------------+-----------+-------+---------+------+-------------------+------------------------------------------------------------------------------------------------------+ | Id | User | Host | db | Command | Time | State | Info | +-----+------------------+-----------+-------+---------+------+-------------------+------------------------------------------------------------------------------------------------------+ | 5 | debian-sys-maint | localhost | mysql | Query | 1589 | Opening tables | ALTER TABLE tables_priv MODIFY Column_priv set('Select','Insert','Update','References') COLL | | | 752 | root | localhost | NULL | Query | 0 | NULL | show processlist | +-----+------------------+-----------+-------+---------+------+-------------------+------------------------------------------------------------------------------------------------------+ 2 rows in set (0.00 sec)

• Can Office Project Server 2010 handle issue tracking?

  - by JL

  I have a scenario where I want to be able to allow customers to login to a customer facing portal on the web, and log issues / bugs. Internal team members should then be notified via email and the issue should be logged in Project Server. The ticket status should be Open, until either resolved or close, where the customer will be notified via email. Is this possible to do using Microsoft Project Server 2010? The question could also be can customers submit bugs to office 2010 projects via a custom web form of some kind, and can project handle the back-end gracefully.

• What specs to consider when buying SSD?

  - by penyuan

  When I bought "traditional" hard drives, I have been told to consider specs like RPM (5400, 7200, etc.), buffer size (16MB, 32MB etc.), and interface (IDE, SATA, etc.). (did I miss something?) What about solid state drives (SSD)? What are some important specs to consider in terms of performance and reliability? By the way, are SSDs just as reliable as traditional hard drives now? A couple years ago I heard they're not, but that's a "long time" ago now. Thanks for your answer.

• Copy & Paste Images Wiki functionality?

  - by Jakub

  I was discussing this with some coworkers, they would like a wiki, but are turned off by the need to constantly [browse] and [upload] files. They like the functionality of Lotus Notes that they can copy & paste screenshots (or crops etc) directly into Notes databases / libraries. But they are not fans of Lotus notes behond that (performance, etc,) Anyone work with a free (open source hopefully) wiki of documenting application that just allows copy & paste of text & image content? Would be great to have one internally installed that we could use for documentation without constantly uploading/attaching files. Not sure if I am asking for functionality that is not available in a browser.

• Video problem with Windows 7 Games

  - by Jordan 1GT

  I have a Dell xps M1330 which originally ran Vista, but I upgraded to Windows 7. When I try to run a Win 7 game like spider solitaire I receive the following message: "The game is running in software rendering mode. Hardware acceleration is either disabled or not supported by your video card driver which could slow down game performance. Make sure you have the latest video card driver installed and that hardware acceleration is turned on." I confirmed that hardware acceleration is turned on. When I go to Dell's site, I'm told there is no later video driver. When I run the game it runs very choppy. I wouldn't care, but I loaded a .pptx file which is doing strange things in normal view and I suspect may be related to the same video problem. Any ideas?

• SoX on Windows 7 64-Bit Outfile Missing

  - by Christian

  I have come across the strangest problem when trying to run sox.exe on my Windows 7 installation. Whenever I try and record audio it works without any issues but it will not output an audio file. The crazy thing is that when I use the play command it successfully plays what I just recorded. Has anyone ever heard of this happening? Here are the commands (and output) that I'm using: C:\Program Files (x86)\Vox\sox-14-4-0>sox -d test.wav trim 0 00:05 Input File : 'default' (waveaudio) Channels : 2 Sample Rate : 48000 Precision : 16-bit Sample Encoding: 16-bit Signed Integer PCM In:0.00% 00:00:05.03 [00:00:00.00] Out:240k [ | ] Clip:0 Done.

• What rights does an employer have to the employee's computer?

  - by Terrence Brannon

  What access rights should an employee grant an employer for a work computer? For instance, let's assume that the business people come to the IT lab late at night for discussions with the CIO and they use my computer for reading email and general web surfing. In a sense, this means that they are taking full or partial responsibility for any security issues that crop up that get traced back to the employee's machine. Perhaps the proper way to provide a computer to an employee is to give him full and exclusive use of it while employed. Only supervised access (such as hardware/software maintenance) should be acceptable.

• creating decision tree based troubleshooting documentation?

  - by Joseph

  We troubleshoot a lot of server and network issues and follow a loose set of steps on what to do in different cases. With more and more people and responsibility, the need for standardization is needed so we don't miss something. I know I could accomplish what I want using flowcharts, but I'd like to do something similar to a "Choose Your Own Adventure" style. I think this is pretty much the same as what support call centers seem to do. Are there any tools to make creating such documentation easier? I'm looking for a web based approach if possible.

• AWS: Should my EC2 and RDS instances be in the same Availability Zone?

  - by DOOManiac

  I just noticed that all of our EC2 instances are in zone us-west-2b, but our Multi-AZ RDS instance is in us-west-2a. Performance-wise everything seems to be okay, and it will be a hassle to "move" the instances to one place since you have to stop and re-create them all. However if either of the two zones goes down when we will have some downtime; if everything is in one zone then at least we have a higher chance of not being in the zone that has downtime... Is this something worth fixing, or am I over-thinking it? (I was about to purchase some EC2 Reserved Instances, which are tied to specific AZs, so I wanted to make sure before going through with it) Thanks!

• Open Source Visualization and Dashboard Software

  I am working on an open source Application Performance Monitoring (APM) software and looking for a visualization tool with dashboard capabilities.

Here's the list of features I am interested in: Must-Have Open Source license API to submit real time data Web-based visualization interface Persistence - file or database Nice-To-Have Dashboard Capabilities: Allow users to select a few metrics (CPU, Heap Usage, # of Active Users etc.) and place them on a single page for easier monitoring. Any suggestions?
