• Apache crashing at random intervals. Can not find a reason in log files

  - by Nick Downton

  We are having an issue with a VPS running plesk 9.5 on ubuntu 8.04 At seemingly random intervals Apache will disappear and needs to be started manually. I have checked the apache error log, /var/log/messages, individual virtual host apache error files and cannot find anything that coincides with the time of the failure. dmesg is empty which is a bit odd. We have also had the psa service go down for no apparent reason but apache stay up. I'm at a loss to diagnose this really because all the log files I can find do not point to any issues. Are there any others I can look at? Memory usage sits at about 55% (out of 400mb) and it isn't a particularly high trafficed server. Any pointers as to where else I can find out what is going on would be very much appreciated. Nick

• How Do You Stress-Test Your Hard Drives?

  - by MetaHyperBolic

  When looking for large new drives (= 1 TB) on newegg and the like, I note a number of reviews talking about drives being either D.O.A. or hitting the Click of Death (or even releasing the Magic Smoke) within a week or so of use. A portion of the reviews mention this phenomenon whether the drive in question is Western Digital or Hitachi or whatever. For those of you using Windows, what do you to: 1) Place a large initial stress on the drive to see if it can take it? For how long? 2) Test the drive afterwards (presumably with some sort of S.M.A.R.T. tool or others) to see if any negative changes have been noted? Note: This is one component of a larger plan for both high-availability and backups for my home data.

• Taking an image backup of an entire server?

  - by WarDoGG

  I am currently using a dedicated server for my hosting needs. However, the costs are too high and I would like to suspend everything until I work out my business strategy again. Is there a way I can take a complete backup of the filesystem and run it in VMWare ? I cannot just copy the entire filesystem because there are lots of tools installed and tight changes to the server configuration files I myself dont know about (by the developers), but I need a snapshot of the entire disk image along with processes installed and everything is as is because for development needs, I need to work on this copy in VMWare or VirtualBox etc. Is it possible for me to take a full image copy ? How do I do it ?

• Video encoding for archival

  - by Jim

  I would like to archive some home videos (DV). I don't need to save them losslessly, but I would like to encode them in something high-quality. What format is both pretty indistinguishable from the original and will likely be readable 15 years from now? WMA makes me nervous, because it's only one company that makes it, and they're constantly coming out with newer formats. (VLC couldn't open my WMAs that Windows Movie Maker made.) Other things I've considered are h.264, Ogg Theora, DivX, and Xvid. I don't mind paying for something, but usually that means the format is owned by only one vendor.

• Formatting a 5.25" floppy disk

  - by Spütnik

  So after the massive trouble of finding a 5.25" floppy drive and a connecting it up, then changing the BIOS so it's set as my A: drive, I tried to format a couple of high-density 1.2MB floppy disks using the "format A:" command in Command Prompt. Both times it formatted only 160KB and left it at that. If I then check the amount of space on those disks, it then comes up as 160KB. Why is this the case? How can I get my the full value out of my 1.2MB? For reference, I have a Mitsubishi MF504C-318UG, which should support 1.2MB disks.

• Sound card problem, no audio device detected

  - by Paul

  I bought a new sound card because my built in sound card did not function. When I open YouTube, Media Player or anything that can create a sound my computer will hang up and sometimes when I start my computer it will hang when the Windows XP sound will activate. Update: My computer has no audio. It says NO AUDIO DEVICE. I already installed Realtek AC97 and Realtek High Definition Audio Driver and I also pasted stream.dll to the Windows and system32 folders and I restarted my computer but it still says NO AUDIO DEVICE. Please help me. Thanks

• How to diagnose a Windows XP hard crash

  - by Jon

  I have a 64-bit Windows XP machine which has hard crashed several times today. The symptoms are that the screen just goes blank, then the reboot cycle starts. There is no blue screen and even though it is switched on, no crash dump file is created. On all occasions it has happened during a period of high CPU/memory activity. I have run a full Dell diagnostics with no failures. Any ideas how to track this down further? Thanks.

• shut down FTP from IIS 6 after <X> failed login attempts

  - by Justin C

  Is there a setting in IIS 6 to turn an FTP site off after a specified number of failed login attempts? It has already been documented on this site that a Windows server sitting on a static IP address can record tens of thousands of failed login attempts a month. One server I maintain has had tens of thousands of attempts made against the FTP port. I have solid passwords in place, so I am not overly concerned. I rarely have to use the FTP, so for the most part I turn it on and off as I need it. Sometimes though I forget to turn it off when I am done, only to find the next day that my EventLog is full of audit failures. I would want to set a high number, in case I just messed up the password. Something like if 50 failed login attempts happen, just turn off the FTP site. Then if I need it later I can just start it again.

• Sending a large number of mails causing problems on CentOS 6 / Plesk 10

  - by papakost

  I have a VPS running CentOS 6. When the system tries to send daily newsletter, after some time (e.g. after sending about 2000 emails), I get error "Unable to send mail" and the system memory goes really high. Till this moment, the mails are delivered normally. The rest symptoms are: I cannot see anything on /var/log/maillog (File seems not to be written) All files on /var/spool/mail have 0 bytes size. From time to time on httpd log I get errors like: /usr/sbin/sendmail: error while loading shared libraries: libc.so.6: cannot open shared object file: Error 23 "Activate mail service on domain" setting in Plesk is deactivated. Any idea on what's going wrong here?

• VMWare Workstation Dev Machine Disks: one fast or four echofriendly raid?

  - by Avi

  I'm building a new dev computer. It will be running a few VMWare Worksation virtual machines - A dev machine running VS-2010, a build machine, a version-control machine, a web server for testing, a "personal" machine running office etc. I'll be connecting the computer to my stereo, so I'll also be running iTunes (possible on a dedicated VM) and I want the computer to be a silent one. I'll probably use an Antec P183 case. I was advised on Serverfault to use Raid10 for performance. Raid 10 uses 4 disks. So, my question is as follows: In terms of heat, noise, reliability, warranty, price, capacity and performance, what would you suggest: A Raid10 4 disk array using eco-friendly disks such as the $94 1TB Western Digital Caviar Green, or one high performance disk such as the 2TB Western Digital Caviar Black at $280?

• apache - subdomains are slower?

  - by matthewsteiner

  Using apache benchmark, I ran the exact same php application at my root domain and a subdomain. Even with multiple tests and high request numbers, the requests per second perform extremely differently. I mean something like this: example.com - 1200 requests per second bench.example.com - 50 requests per second What could be affecting this? These aren't using databases or anything, just mainly getting a simple page displaying. But it's the same app for both of them, and I'm wondering why they perform so differently. Ideas?

• Symlink across local volumes in webroot?

  - by geerlingguy

  I am looking for a good short-term solution to storage space concerns on my website. Currently, I have all uploaded files (flash video, images, etc.) inside the 'files' directory in my web root (/home/account/public_html/files). That directory is located on my high-speed main hard drive (a 15k SCSI drive). I have another drive with much more capacity, but spinning at 10k rpm (so still fast, but not as good for random reads/writes as the main drive. The entire drive is mounted at /backup Right now I'm just using it as a backup volume. I would like to create a symlink from my /home/account/public_html/files folder to /backup/files, and have all files reside on the second drive. However, if someone accesses a file at http://www.example.com/files/filename.jpg, would it still work if I symlinked to the second drive? (Basically, would Apache/PHP automatically know to follow the symlink for that directory?).

• nginx errors: upstream timed out (110: Connection timed out)

  - by Sparsh Gupta

  Hi, I have a nginx server with 5 backend servers. We serve around 400-500 requests/second. I have started getting a large number of Upstream Timed out errors (110: Connection timed out) Error string in error.log looks like 2011/01/10 21:59:46 [error] 1153#0: *1699246778 upstream timed out (110: Connection timed out) while reading response header from upstream, client: {IP}, server: {domain}, request: "GET {URL} HTTP/1.1", upstream: "http://{backend_server}:80/{url}", host: "{domain}", referrer: "{referrer}" Any suggestions how to debug such errors. I am unable to find a munin plugin to keep a check on number of upstream errors. Sometime the number of errors per day is way too high and somedays its a more decent 3 digit number. A munin graph would probably help us finding out any pattern or correlation with anything else How can we make the number of such error as ZERO

• TCP 30 small packets per second flood connection with server

  - by Denis Ermolin

  I'm testing connection with flash client and cloud server(boost::asio for software) over TCP connection. My connection with server already is really poor - 120 ms ping in average. I found when i start to send packets with 2 bytes size (without tcp header) with speed 30 packets/s - ping grow to 170-200 average. I think that it's really bad and my bad connection and bad cloud provider is reason for this high ping without any load. What do you think? (I tested my software - it can compute about 50k small packets/s so software is not a problem). I measure my ping through flash client - send packet with timestamp and immediatly send from server to client.

• Configuring bridged network connection --- Windows 7 host, Ubuntu 10.04 guest --- VMWare Workstation 8

  - by H3br3wHamm3r81

  Here is my IPCONFIG /ALL from the host (Windows 7 64-bit): Here is my IFCONFIG from the guest (Ubuntu 10.04): To be honest, I don't have experience configuring a network between a host and a guest in VMWare (a virtual machine). I've searched high and low on the internet, but I haven't seen anything that can help. Perhaps I'm just not using the right keywords when I search. Nevertheless, does anyone here have any experience with establishing a network connection? Edit: One important note. I don't use DHCP to provide private addresses to the hosts on my LAN. I use "static" IP addresses on my internal network by configuring each IP address manually in the host's network configuration utility (I have TV's, XBOX 360, and a few PC's). I would like to configure the IP on the virtual machine guest manually as well. The reason is because my XBOX 360 only works properly using a static IP address. It will kick me off XBOX Live if it has one given by the router (via DHCP).

• SQL server availability issue: large query stops other connections from connecting

  - by Carlos

  I've got a high-spec (multicore, RAID) server running MS SQL 2008, with several databases on it. I have a low throughput process that periodically needs a small amount of information from one of the DBs, and the code seems to work fine. However, sometimes when one of my colleagues does a huge query against one of the other DBs, I see full CPU usage on the machine, and connections from my app time out. Why does this happen? I would have thought the many cores and harddisks would somehow (together with cleverly written DB server) be able to keep at least some of the resources free for other apps? I'm pretty sure he doesn't use multiple connections for his query. What can I do to prevent this?

• Why do some machines respond with many RST packets instead of RST-ACK to refuse a connection?

  - by Michael J. Gray

  I have recently been trying to track down a problem with one of our systems and have noticed that it is simply not allowed to connect to a remote machine. However, the remote machine (not controlled by us) is responding to our request for a connection with many TCP RST packets on a different port (26469, 26497, 26498) than the one we originated on (53). It simply wouldn't let up at one point and flooded us with about 10 packets/second for an hour or two of only RST on those obscure high ports. Out of the thousands of nodes we're connecting to, this is the only one ever to show this behavior. What could possibly cause this? EDIT Below is a screenshot of Wireshark when it happened. I don't have the actual dump anymore and can't reproduce this specific scenario every time. Basically, we sent a SYN and immediately got RST on an odd port and so we respond with RST and just keep going back and forth.

• Create a dependent drop down list in a single cell in Excel

  - by Larry Anderson

  I am trying to create a dependent drop down list for a High School. The User will select cell A1, Click on Hallway 3(for example), then the user will click on cell A1 again and then select the Room #, 325 (for example). The final result should be that cell A1 shows 325. I can create the first drop down list, but the second part is where I am having great trouble. I am using Excel 2010. Any help would be appreciated. Thanks

• How to find malicious IPs?

  - by alfish

  Cacti shows irregular and pretty steady high bandwidth to my server (40x the normal) so I guess the server is udnder some sort of DDoS attack. The incoming bandwidth has not paralyzed my server, but of course consuming the bandwidth and affects performance so I am keen to figure out the possible culprits IPs add them to my deny list or otherwise counter them. When I run: netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n I get a long list of IPs with up to 400 connections each. I checked the most numerous occurring IPs but they come from my CDN. So I am wondering what is the best way to help monitor the requests that each IP make in order to pinpoint the malicious ones. I am using Ubuntu server. Thanks

• Any ramifications to disabling ClearPageFile

  - by user34710

  I am runing a Dell XPS 15z with a quad core I7, 8gb ram, 7200rpm hdd, windows 7 ultimate. My laptop was taking around 3 minutes to shut down, which seemed far too high to me. I did a bit of investigation, and it seemed that the ClearPageFile reg entry was set to 1, meaning that upon shutdown my pagefile.sys was being cleared before actually shutting the machine down. When I disable this setting, my laptop shuts down in about 20 seconds - clearly a big gain. My question is, are there any side effects of having this turned off (other than the security risk of the HDD being stolen, and still having any important info that was in the RAM up for grabs)?

• Access a windows dynamic hard drive through a virtual machine on ubuntu?

  - by Enigma

  I have a Windows 7 OS and am thinking about transitioning to a dual boot set up with Ubuntu 12.04. From what I recall, it is not possible to natively access Dynamic Windows Partitions in a Linux OS. My thought is that it might be possible to have a virtual machine (running windows) installed within Ubuntu access the physical dynamic drive. The problem comes to whether VMWare can access the physical disk "high enough" to be able to mount it within the windows virtual machine as a native device or if it gets passed through from the native Linux OS. This is really the only thing holding me back from switching to a dual-boot set up as the dynamic disk is made up of 4 or 5 hard drives and I would very much like access to the data on both OS's. Alternatively, is there another solution for combining multiple physical hard drives into one virtual hard drive that would be readable on both OS's?

• Suggestions for someone wanting to become a Laptop Reseller

  - by Josh B.

  First of all, to give you a little background... I have had my Microsoft A+ for several years now. I used to run a small business repairing Xbox 360 consoles and I am currently a Network Engineer for a company in Ohio. I definitely know my way around a computer. I miss running a small business on the side and I'd like to get something going again. There is a really high demand in my area for Laptops and I was thinking about starting a small Laptop store out of my house. What is the best way to do this? I was assuming that the best way would be to buy barebones systems and build them yourself. If this is the best method, I would be very interested in any resources to get parts and such. Apparently Laptop parts aren't the easiest thing to come by (especially at a good price). Does anyone have any suggestions about how to get something like this going?

• Tests for hard drive health

  - by Samik R

  I have a 5-year old hard drive (bought new at the time), but it was sitting in my closet for 5 years, unused. I have just started using it, and seems to be getting a whirring sound (rather distinct from the other noises like fans etc.). I ran a few diagnostics tests, like Seagate's SeaTools, and the SMART test, and a few generic tests and all passed. Should I be concerned? Is there any other test that I should run? It's an internal IDE WD 5400RPM drive. Being used for a desktop, which is itself pretty high-end (AMD Phenom II X6 1100T, AMD Radeon GPU etc.), but would be used rather occasionally to begin with (avg. 1-2 hrs. per day). Thanks for any pointers.

• How long until the chirping stops or what can I do to make it stop?

  - by MadBurn

  I know computers, I have been fixing them and building them for over a decade... but I don't know the exact electronics of them. My personal desktop PC is making an irregular, but constant, extremely high pitched chirping noise. I know this could be my hard drive, but I've heard that noise before and I believe this is a capacitor or part of the electronics. This noise is right at the edge of my hearing and I can feel it more than I can hear it. After a while, it starts to give me a headache and makes me physically sick. How long will this last? Is there anything I can do to fix it (short of replacing the entire motherboard)?
