• ARR servers in the Load Balancing pool automatically go from unavailable to available

  - by Chris

  I have 3 IIS web servers in an ARR web farm. When we do rolling releases, we take one server offline as a backup server and move it into an "Unavailable State" I have noticed that with ARR, servers will not stay in this state...they come back online automatically hours or days later. Does anyone know how to remedy this situation? This is very bad as the server that is down is typically not running the correct version of our code. I need to keep a server unavailable until i tell it otherwise.

• Best network tuning variables for a Linux proxy

  - by smarthall

  What are the best settings to tune so that Linux can handle a very large amount of TCP connections such as would be seen by a proxy server or a webserver? I'm using Centos6 and squid and am seeing a large amount of TIME_WAIT connections backing up until finally the machine stops responding. The machine isn't loaded at the time, and is having trouble making ingoing and outgoing connections. I've had several suggestions of tuning /proc/sys/net/ipv4/tcp_tw_reuse and /proc/sys/net/ipv4/tcp_tw_reuse but they mention bad interactions with load balancers and NAT both of which are used in my situation.

• Separate brightness/power-saving settings for multiple monitors

  - by MariusMatutiae

  At home, I connect my laptop to an external monitor. Under Linux X server, it works perfectly. Occasionally I watch a movie on the external monitor. When I do, I would like to fold the laptop shut, and just relax. This however triggers my settings for dimming the screen after 10 minutes of inactivity, which in turn extends to the external monitor. I know I could solve the problem by setting dimming to "Never", but this is a waste, causes the laptop to overheat, and is bad for the normal laptop use. How can I set the power saving/brightness specs for the external monitor, independently of the onboard one? I run Debian or Arch, under KDE.

• What is the right way to use Internet Sharing in OS X?

  - by Bob King

  For a while now I've been using the Wireless in my Mac Mini as a seperate WiFi access point because my main router doesn't quite cover my whole house. There is a dedicated CAT 5E line down to the Mini, which has a static IP address. I've turned Internet Sharing on, using Airport/WiFi but it seems my options for security are limited. Can I do WPA2? Also, it seems like my iPhone only connects 25% of the time, and the rest of the time it claims I've given a bad password. I've tried "Forget this network" repeatedly.

• USB to DVI adapter to get around two monitor limit of my graphics card?

  - by JavaJosh94

  My graphics card is an nVidia GTS 450 which will only run two monitors at a time, but I'd like to add a third one. Will I be able to do that using a USB to DVI adapter or would the limit still be there? Also I've been told the video quality is really bad with these adapters, so is the quality of the video output by these adapters okay for things like web browsing and working on office thing? And is it worth the $60 or would I be better off just buying a cheep second card?

• using Team foundation server

  - by joe

  I am using Team foundation server / visual studio as a client, to manage my visual foxpro source code. everytime i "checkout for edit" all my folders and files are read only and when i open my projects, it is like if the project is opened for the first time, asking me if i would like to set the current path as the default path... this is causing other serious problems as bad reference to "missing library files", which are actually not missing. i know Visual foxpro is old stuff...i hope someone who went through the same errors could help me out. thanks a lot guys

• Debian/Ubuntu apt or pbuilder without root privileges?

  - by Tem Pora

  I want to use apt or pbuilder to build a package in user's home directory. The home directory has enough space to hold the package's source, its dependencies and binary output. But the apt and pbuilder documents say that you have to be a root user (sudo) to use it. It's frustrating, as the only way now I have at my disposal is to build the package from source or use the dumba$$ (sorry for bad language) dpkg and in both cases figure out every dependency manually, create the dir layout manually and install the built things manually. Now if I can do all these things manually, why the tool writers (apt) think that doing so using their tool (apt) is somehow more special/dangerous? I don't want to use root privileges JUST to build and test a user-land package. If I am NOT allowed to do anything outside my home dir then why NOT the apt or pbuilder type commands be allowed to "build" something in my home dir without root privileges? I just want to use their functionality. It seems there is nothing like Gentoo Prefix from Debian

• How can I make the icon font color on a windows 7 prof desktop work?

  - by naxa

  I have C:\Windows\Web\Wallpaper\Scenes\img25.jpg as wallpaper (I think it's a standard windows wallpaper.) The desktop icon font color is white. It cannot be read without heavy eye pain. I want it to be black. I couldn't change the icon font color in advanced properties (ie the good old window color settings dialog) for aero for windows 7 professional x32. I've heard that the icon font color should change automatically to suit my needs, it doesn't work as advertised in my scenario. How could I fix it and rescue my eyes from popping out? EDIT screenshot attached. sorry for bad english.

• How to configure an ASUS motherboard.

  - by Absolute0

  I have an ASUS P7P55-M motherboard running with an Intel Core i5-750 processor and 4 GB RAM with 1600 MT/s speed. For some reason the default settings of the motherboard make all the components run at half their optimums. I have switched to the "D.O.C.P." profile and supposedly everything is as it's supposed to be (verified with CPU-Z). There is also an "X.M.P." profile and a manual one. Are either of the DOCP or XMP safe to go with? I wouldn't use the manual mode as I would likely mess something up real bad. XMP seems to be more memory oriented.

• Install newer version of GCC in Knoppix

  - by Z boson

  I have Knoppix 7.30 installed on a USB with a persistent file. It comes with GCC 4.7.2. I would like to install GCC 4.9.x or 4.8.x. Being that Knopppix is based on Debian I would normally do something like apt-get upgrade But as far as I understand it's not recommended to do this with Knoppix. Warning: apt-get upgrade is a BAD IDEA. It will, quite probably, render your KNOPPIX remaster unbootable, or broken in some way. A far safer method is to only upgrade packages as necessary. I can say from experience that that is the cse. So how should I go about installing GCC 4.9? Another option would be to "remaster" knoppix to use GCC 4.9 by default rather than install it with a persistent file. I would be happy with either solution.

• My BrowserHelperObject is detected by avg as a malware, what is going wrong.

  - by BHOdevelopper

  Hi i'm building a BrowserHelperObject in c++ for Internet Explorer 8. It is a friendly add-on that gives you fonctionalities in a sidebar. The thing is that when you download the add-on executable from the web, AVG (AntiVirusGuard) detects the executable file as a malware. I did a lot of research and i can't find a way to not being seen as a bad malware. I know that BrowserHelperObject are often seen as malware, but mine is just a good and friendly add-on. Does anyone as info on how antivirus detection works and what can i do to prevent being seen as a malware. What has to be done to the BHO to pass avg detection ? Thank you.

• Burn iTunes playlist to Audio Image

  - by MikeHoss

  I have Snow Leopard on an early model MacBook Pro. The CD Drive has been giving me fits the last few months -- I stick a blank CD in it, and it claims it's bad and spits it out. I can go through a pile of brand-new CD's and it will choose 1 out of 7 that it wants to use, even though all the CD's come from the same package. The rejected CD's work fine on a Linux machine I have. I need to burn an audio CD from iTunes and my thought was: Burn playlist to audio CD Image file (Red Book image?) Copy ISO file to Linux Machine Use Linux machine to burn audio image to a CD But looking around, it doesn't seem that iTunes on OSX will support this. I was wondering if anyone else has accomplished this.

• Network? or router? problem

  - by Robert H Mercer

  I have two computers networked through a Netgear WG914 router which is connected to an Ipstar satellite modem via the RG47 LAN connector. The main computer is running Windows 7 Pro 64bit and the secondary computer is running Windows 7 Home Edition 32bit. On occasion there is a loss of internet connection usually on the main computer, often followed by a loss on the secondary comuter. Not, however, always the case. Windows troubleshooter, naturally, is about as much use as a politician in government.......NONE. There appears to be no problem with the ISP bad as it is and often the connection will be remade without any help from me. The difference in the OS's is not of any relevance since I had this problem before I changed over to Windows 7. Not being a nerd when it comes to networking I wonder if anyone has any constructive suggestions.

• harddrive problem (usb external)

  - by masfenix

  Hey guys I am using a Maxtor One Touch 3 given to my by my uncle. It is connected through USB2.0 When I plug it in, XP installs it and says "the device is ready to use". But it dosnt show up on my computer. It dosn't even show up in disk mangement. I then install Acronis Disk Director (which detects it) but marks it as offline. if i try to change it to online, nothing happens. (actually the lights on the HD blink - meaning communication and goes back into offline mode). The lights on the HD return to a solid which mean "working properly". Here is a screenshot: Is there any way to extract the data off the drive? is the drive corrupt? sitll useable? edit: DISKPART screenshot: edit2: I ran Seagate diagnostic tool and this came up: Long Generic - Started 9/10/2010 6:44:36 PM Bad LBA: 0 Unable to repair Long Generic - FAIL 9/10/2010 6:46:41 PM SeaTools Test Code: 4

• How to reliably run a batch job every 5 seconds?

  - by Benjamin

  I'm building an application where the sending of all notifications (email, SMS, fax) will be asynchronous. The application will write the notifications to the database, and a batch job will read these notifications and send them with the appropriate transport. I was first reading at ways to run cron faster than the minute, and realized this was a bad idea. The batch scripts are written in PHP, and I guess that writing a proper daemon would be quite an overhead (though I'm open to any suggestion, as PHP car run indefinitely as well). What I have in mind is a solution that would: Run the PHP script every 5 seconds Check that the previous run has finished, or abort (never 2 concurrent batches running) Kill the script if live for more than x minutes (a security in case it hangs) Start with the system (if a reboot occurs) Any idea how to do this?

• Ubuntu doesn't start and I can't login [migrated]

  - by Meph00

  My ubuntu 13.04 doesn't boot anymore. Eternal black screen. If I press ALT+CTRL+F1 I see that it's stucked on "Checking battery state [OK]." I'd like to try to go with sudo apt-get install gdm but I can't login on terminal tty2, tty3 etc. They correctly ask for my nickname, then they make me wait a lot, ask for password and make me wait again. After a lot of time (... a lot) the best I could achieve was visualizing "Documentantion https://help.ubuntu.com". I can never reach the point where I can give commands. Plus, during the long pauses, every 2 minutes it gives a messagge like this: INFO: task XXX blocked for more than 120 seconds. Any suggestion? Sorry for my bad english and thanks everyone for the attention.

• When is it time to buy a new hard drive, and what considerations go into buying a new hard drive?

  - by user1125620

  I've had my current hard drive for about 4-5 years now, and I've never had a problem with it before, but now it's making whirring noises. It's done this before and, last time, the noise did go away the next day, but I have accumulated quite a bit of information that I wouldn't want to lose on the drive. HD Tune Pro and Berlac Advisor both said the drive was healthy, and I wouldn't want to get a new one unless it was absolutely necessary or was going to show drastic performance improvements. My only knock against the drive would be that Visual Studio takes longer to load than I'd like it to. HD Tune Pro says the average read speed is 54.3MB/s. I'm not sure if that's good or bad, but it seems about average compared to similar drives on http://www.hdtune.com/testresults.html. Model #: WDC WD5000AAJS-22YFA0 So, should hard drives be replaced after a certain amount of time? Has mine reached that point? Would a new hard drive be any faster?

• How to get Apache web server to run on other computers?

  - by Eric

  I have been using Apache Web Server for a while now and one thing I have noticed is that outside of my computer I can not access it. I use my Apache server for PHP development on my computer, but I would like to access stuff I have made outside of my computer. I am on a linksys router network. I usually run it of http://localhost/ or http://127.0.0.1/. I IPCONFIGED my computer and got 192.168.1.105 so I went there with my browser and got the page just fine. I tried doing this on another computer on the same network but it didn't work. How do I fix this? Sorry about the bad wording. I am in ah hurry Information you might need to know: Server: Apache 2.2 Operating System: Windows 7 ULTIMATE

• Is there a limit on the number of USB external drives?

  - by Beska

  I've got three external HDDs, all My Books, 500 GB, 750 GB, and 1 TB. If I hook one or two of them up to a computer, everything seems fine. If I hook all three of them to a computer (I've tried this on two different computers, one running Windows XP, one running Windows Vista), the bootup time goes up by more than an order of magnitude. It can suddenly take about 10-20 minutes to boot the machine, whereas before it might take a minute. All three drives work fine on their own. I'm not using any kind of hub; all three are plugged directly into the machine. Is this associated with some kind of inherent limit in USB? Is this bad hardware design in the CPU box? Is this a My Book problem?

• NAT and NGINX on the same server

  - by Morten

  I'm setting up a VPC cluster for my collaborative todo list application www.getdoneapp.com. To have my servers on the private network I need a NAT server so my servers on the private network can connect to the internet to receive updates and what not. The NAT server will consume an elastic IP address, so I'm wondering if I can just have that NAT server run nginx to direct traffic to my internal servers for HTTP. So the question is, is it a bad idea to run NGINX and NAT on the same server, or should I go for consuming 2 elastic IP addresses?

• Ubuntu hang, and cannot be soft-reset after resuming from stand by mode

  - by Phuong Nguyen

  I have downgrade my xorg drivers, so I can hibernate and stand by my ubuntu smoothly. However, in some case, there's a problem. My ubuntu get hang. When I tried to switch to console mode (Ctrl+Alt+F1), then I cannot login. The system always reply with an error whenever I tried to press a key. When I press Ctrl+Alt+Del to perform a softreset, here what's it said: [80141.320122] end_request: I/O error, dev sda, sector 193687181 init: control-alt-delete main process (5660) terminated with status 2. This error is not even recorded in syslog. I guess this should be a problem with my hard disk since it said something about a bad sector. Exactly, what kind of error is this?

• Linux web server shared hosting file errors

  - by dfilkovi

  I'm using a shared hosting to host my website and have some problems with files from time to time. First, one of my file (php) was missing a part of code (nothing to do with hackers just a random piece of code was missing), then after some time a value inside a mysql table was also missing a part, then a whole table column disappeared, after that a whole file on my site disappeared and lastly again some code from a file disappeared, my hosting service says it has nothing to do with them, but this is stupid, how can this happen, no hacker attack could do such a thing, I believe it's some kind of a disk corruption or bad backup. Anyone have any ideas?

• What are possible causes of keyboard lag on my desktop machine?

  - by Jer

  I am running Windows 7 and began experiencing keyboard lag in most applications, and it seems to be getting worse. Certain websites are the worst - on some, I can type a sentence, take my hands off the keyboard, and watch the characters continue to appear on the screen for several seconds. Others are not as bad, but still noticeable and annoying. I just started noticing it in non-browser applications (e.g. Outlook) as well. I've disabled all extensions in Firefox, rebooted my machine, and that did nothing. There is nothing using much memory or cpu cycles, even when the lag is occurring. This is a machine at work with very strict controls over what can be installed, so the chances of any kind of malware are very slim. I don't believe anything as been installed since before the problem started. What could be causing this, and/or what can I do to debug?

• Host forwarding fails, server is up, domain name tests ambiguous

  - by jayunit100

  I have a domain name registered with http://www.registryrocket.com/ The "main" site, which is called rudolfcode.net, is registered under godaddy, and forwards to a heroku site (rudolfcode.herokuapp.com). I have found that the main site, rudolfcode.net works, but the hostgator forwarding has stopped working (firefox simply fails when you point to http://www.rudolflabs.com, which is the domain name registered by hostgator). How can I debug this issue ? Finally, I have tried to run some DNS tests, and here are the results : Im not sure what the failures mean .... But Im pretty sure that "Conecting to WWW Home Page" failed is a pretty bad sign ! Thanks.
