• x86 exceptions and flags

  - by b-gen-jack-o-neill

  Hi, please, I know that when you for example divide by zero, the aproptiate flag is set in CPU flag register. But today I read that there are special interrupt vectors (I think the first 16 in IVT) that are used for such conditions like dividing by zero. So, what I want to ask is, does any situation that couses change som flag also triggers apropriate interrupt? Becouse in school, we used conditional jumps that checks wheather carry flag has been set or not, and I don´t remember there was some interrupt triggerd by that. So I am pretty confused now.

• Ubuntu Linux: Process swap memory and memory usage

  - by David Halter

  My Ubuntu eats more memory than the task manager is showing: sudo ps -e --format rss | awk 'BEGIN{c=0} {c+=$1} END{print c/1024}' 1043.84 free -m total used free shared buffers cached Mem: 3860 1878 1982 0 20 679 -/+ buffers/cache: 1178 2681 Swap: 2729 1035 1693 That's strange. Can someone explain this difference? But what is more important: I'd like to know how much memory a process is really using. I don't want to know the virtual memory size, but rather the resident memory plus swap of a process. I have also tried to output the format param "sz" of 'ps', but the sum of this is to high (5450 MB) (param 'size' gives 8323.45 MB). Are there any other options? I really want to use this, to determine which programs/processes are eating to much memory (and swap), to kill them, because hibernate might not be working if the swap partition is to little.

• nginx conditional Accept header

  - by manu_v

  Some mobile devices send the following incorrect requests to our servers : GET / HTTP/1.0 Accept: User-Agent : xxx The empty Accept header causes our Ruby on Rails server to throw back a 500 error. In Apache, the following directive allows us to rewrite the header before sending it to the application RoR server in order to cope with the broken devices : RequestHeader edit Accept ^$ "*/*" early We're currently setting up nginx, but achieving the same work-around is proving difficult. We are able to set : proxy_set_header Accept */*; However, this seems to have to be done inconditionally. Whenever trying to do : if ($http_accept !~ ".") { proxy_set_header Accept */*; } It complains with the message : "proxy_set_header" directive is not allowed here So, using nginx, how can we set the HTTP Accept header to */* when it is empty before sending the request to the application server ?

• Scheduling VMWare ESXi 4.1 VM Restart

  - by Robin Day

  We had a virtual machine running on a VMWare Server host on Windows Server 2003. The machine is set up with non persistent disks. We had a windows task schedule set up that ran a batch file to reset the machine each week so that it returned to it's original state. The batch file that we had running was: "C:\Program Files\VMware\VMware Server\vmware-cmd" "C:\Virtual Machines\VirtualMachineName\VirtualMachineName.vmx" stop hard "C:\Program Files\VMware\VMware Server\vmware-cmd" "C:\Virtual Machines\VirtualMachineName\VirtualMachineName1.vmx" start We have since migrated this machine to the free version of ESXi 4.1. Can anyone let me know if and how it is possible to schedule such a restart?

• Internet Explorer defaults to 64-bit version

  - by Tim Long

  My IE8 has suddenly started defaulting to the 64-bit version. I have no idea how or why this has happened, but I suspect it might be linked to the Browser Choice Screen that Microsoft was recently forced to display by EU law. However, many web sites will not display correctly in IE8 x64 (eg. sites that use Adobe Flash or Microsoft Silverlight). I have the 32-bit version of IE pinned to my taskbar and if I launch it manually, everything is fine. But when I click on a URL from another program and IE is not already running, then the 64-bit version gets launched. This really messes with programs like BBC iPlayer which rely heavily on Adbobe Air and Flash. So, how do I get IE8 32-bit version to be the default version again? I've tried using the "default programs" control panel and that doesn;t make any difference (in fact, it doesn't give the choice between x84 and x64 versions, it just lists "internet explorer").

• How to limit my CPU power programmatically on Windows 7?

  - by Ivan

  Whenever I run a CPU-heavy activity (like compressing a big set of files into an archive for example) my CPU switches to its full throttle (maximum frequency) and shuts down of overheat in less than a minute. Instead, I would like it to keep slowed-down slightly to do the task a bit slower but be able to reach the finish. At the same time I don't want to dim my screen brightness or adjust anything else what standard Windows power-saving system does. So how do I actually set a cap to limit my CPU power? The CPU is Core 2 Duo T7250, the OS is Windows 7 32-bit, there seem to be no BIOS settings or jumpers available to configure the frequencies.

• show differences between file and file in (compressed) tar archive

  - by Kyss Tao

  Say I have unpacked a gz-compressed tar file, and do not remember what changes I made to the unpacked files, or I archived a folder a while ago and want to know what has changed to the files since. I can use tar -zd to get an overview. Then, say it shows me file foo has changed. How can I see the changes in this file, i.e. the difference between the file on my file system and the (older) file in the archive (ideally in vimdiff, but diff output would be fine too)?

• Enabling Compiz Viewport Switcher key bindings

  - by David Moles

  I'm running compiz 0.8.2 with compizconfig on Scientific Linux 6.2 with Gnome 2.28.2. In the compizconfig "General Options" I have "Desktop Size" set as follows: Horizontal Virtual Size: 6 Vertical Virtual Size: 1 Number of Desktops: 1 This gets me the layout I want, i.e. 6 workspaces in a horizontal layout. Ctrl-alt-cursor-keys work fine for switching between them. However, I can't figure out how to get key bindings for specific workspaces. I've tried enabling "Viewport Switcher" in compizconfig, and tried various combinations both in "Number-based viewport switching" and "Go to specific viewport", to no apparent effect. My first thought was that something else was eating the specific key bindings I chose, but I think I've tried every combination of shift, control, alt and super (i.e., the Windows key) by now. I tried setting 6 desktops under "General Options" instead of one desktop with horizontal virtual size 6, but that doesn't seem to make a difference either. What am I missing?

• GParted tells me my partition has 1.30 GiB used space but I cannot access its contents

  - by reprogrammer

  I've a ext4 partition (/dev/sda7) for my Linux. And, another (/dev/sda5) for keeping my data. When I installing Ubuntu 10.04 LTS, I set the mount point of /dev/sda5 to "/" and that of /dev/sda5 to "/data". GParted tells me that 1.30 GiB out of 70.12 GiB of /dev/sda5 has been used up. But, the mounted directory "/data" is empty. So, it looks like that my data is there but I cannot access it. Besides, when I set the mount point, I didn't check the "format" box. So, it shouldn't have been formatted. How can I check whether the partition has been formatted? How can I recover my files?

• Windows 7 dual monitor setup: Wallpaper alignment

  - by Tomalak

  I have the following dual-screen set up on my Windows 7 PC: [2][1], that means my secondary monitor is on the right side of my primary monitor. Now I have a dual-screen wallpaper that should stretch across the monitors. I have set it to "Tile" mode. Problem: The wallpaper invariably starts at [1] (left edge of the image being on the left edge of [1]), and then continues on [2]. It basically splits the wrong way, producing a rather awkward look. How can I make the wallpaper appear correctly (i.e. left edge of the image being on the left edge of [2])?

• This weird behaviour from cronjob

  - by The DOCTOR from TARDIS

  I have set the crontab like this: */5 0 * * * /www/permitChat.sh and the /www/permitChat.sh is this: # We are setting the name of file # in the variable along with complete path. sFilePath=`date +\/www\/ChatLogs\/%Y\/%m/%d_%m_%Y.txt` # First we set its permissions to # readable by all users, and then # modify them to be writable by only root. chmod a=r $sFilePath chmod u+w $sFilePath ls -lh $sFilePath The trouble I am facing is, the cron gets executed after 12:00 PM everyday, instead of executing at 12:00 AM to 01:00 AM, every 5 minutes. What could be wrong? All my system variables appear to be synced.

• Apache Virtual Host Configuration

  - by Carl

  I have been searching the internet for an hour now, and I was hoping for a quick hint here so that I could solve my problem a wee bit faster. My virtual server is so far only accessible through an IP address, no DNS entry yet, and so far none needed either. The problem I have is with Apache2, the virtual hosts are puzzling me. What I need is: Access to my project (based on Symfony2) from the outside with the IP address Access to my project from localhost What I have got: Access from the outside results in rendering the websites in /var/www/vhosts/htdocs/default, while from the inside results in rendering the websites in /var/www. Why the difference? What is a recommended configuration for my use case?

• linux ftp server with virtual users

  - by kjertil

  i know there are already similar questions for this matter but the answers doesn't really make much sense to anyone who is not really technically comfortable in Linux. I've already tried articles like these for example: http://howto.gumph.org/content/setup-virtual-users-and-directories-in-vsftpd/ with the result of accidently breaking the whole system. The problem is that, while there are several technical possibilities to set up virtual users with a FTP server, it is not as easy as managing for instance a Filezilla server on Windows. I've seen some Web based GUI's but most of them seems to be out of date. The different flavours of Linux and the large amount of different popular FTP servers also seems to make the matter more complicated. I guess my question is, is there a way, to set up virtual FTP users on Linux without the hastle of having to manually edit PAM, MYSQL and config files?

• Sync Banshee library data.

  - by Dom

  I use Banshee to organise my music, I particularly like its scoring system and I have smart playlists based on it. However, I have two versions of my music library, one on each of my computers. As one of the computers is small I only have a favourite set of songs on that computer rather than my whole collection. The computers are not on a local network, but I do use Ubuntu One for file sharing between them. Is there any way I can synchronise song data (play count, score, skip count ...) and playlist data (including smart playlists that include songs based on this data) between the two computers? This would only be relevant of course for the songs that exist on both computers, the songs that exist on only one would need to be ignored. I did consider putting the library data file (I think it is .xml but I'm not sure) into the shared file and creating a symbolic link to it, but then I wouldn't be able to have a different set of songs on each computer. Thank you.

• Is there a way to control two instantiated systemd services as a single unit?

  - by rascalking

  I've got a couple python web services I'm trying to run on a Fedora 15 box. They're being run by paster, and the only difference in starting them is the config file they read. This seems like a good fit for systemd's instantiated services, but I'd like to be able to control them as a single unit. A systemd target that requires both services seems like the way to approach that. Starting the target does start both services, but stopping the target leaves them running. Here's the service file: [Unit] Description=AUI Instance on Port %i After=syslog.target [Service] WorkingDirectory=/usr/local/share/aui ExecStart=/opt/cogo/bin/paster serve --log-file=/var/log/aui/%i deploy-%i.ini Restart=always RestartSec=2 User=aui Group=aui [Install] WantedBy=multi-user.target And here's the target file: [Unit] Description=AUI [email protected] [email protected] After=syslog.target [Install] WantedBy=multi-user.target Is this kind of grouping even possible with systemd?

• Windows XP/Firewall -- Can't open UDP port 9100 for JetDirect sharing

  - by Barton Chittenden

  I'm setting up my Dad's laptop (Vista) to print to an HP Deskjet printer attached to a Windows XP Desktop box. The XP box is running Windows firewall. Laptop sits on 192.168.1.66, Desktop 192.168.1.65. I set up logging in the firewall, and determined that it is dropping inbound packets on TCP port 9100, used by JetDirect, the printing protocol. I set up an exception on TCP port 9100, allowing access to the local subnet. There's also an entry under the 'allow applications' tab which was marked for the exact printer model. I selected this as well, then tried to print again... I see more dropped packets from 192.168.1.66 to 192.168.1.65 for TCP port 9100. What do I try next?

• How do I create a free server-side database to be accessed via Windows forms and/or browser?

  - by NoCatharsis

  I have no formal education in databasing or programming, but I've learned enough SQL, C++, and C# to at least get started setting up a small database on my company's server. Using MS SQL Server 2008 R2, I have created the database and set up columns with proper data types. However, there seems to be a lot of tweaks and details that are way over my head. Since I would like these data to be accessible to the other 7 or 8 people in my office (preferably via web browser), I'm wondering whether this is the best setup for my situation. The other option I've read about is a LAMPP server, which I assume is the competing free option to Microsoft's Express packages. I know nothing of LAMP servers except from the articles I've read on how to set them up (and I believe I even saw a detailed tutorial somewhere). To summarize, my question is this: Which of these (or any other) server setups would best suit my purposes, keeping in mind that I'm a true novice (but willing to learn), and would like to keep it free until I get more experience?

• Nginx redirect one path to another

  - by SteveEdson

  I'm sure this has been asked before, but I can't find a solution that works. A website has switched CMS services, but has the same domain, how do I set up an nginx rewrite for a single page? E.g. Old Page http://sitedomain.co.uk/content/unique-page-name New page http://sitedomain.co.uk/new-name/unique-page-name Please note, I don't want everything within the content page to be redirected, but literally just the url mentioned above. I have about 9 redirects to set up, non of which fit in a pattern. Thanks! Edit: I found this solution, which seems to be working, except for the fact that it redirects without a slash: if ( $request_filename ~ content/unique-page-name/ ) { rewrite ^ http://sitedomain.co.uk/new-name/unique-page-name/? permanent; } But this redirects to: http://sitedomain.co.uknew-name/unique-page-name/

• MySQL won't stop doing stuff

  - by Felix

  Sorry for the title of the question, here's my problem: I've been trying to set up some scripts that import a lot of stuff hourly from an external source. They seemed to work fine, so I set up a cronjob to run them every hour. One day later I find six or seven instances of that script just hogging the MySQL server, making it unresponsive. I killed their processes, but MySQL was still not responding. I had to kill MySQL, reboot and then MySQL started working again (who knows on what) and being unresponsive (yes, I did remove the scripts from the cronjobs). I SHOW PROCESSLISTed and killed every process I could find. Still nothing, MySQL is hogging the HDD and is at the top of top and making the server load go up in the sky. I don't know what to do, if I kill and start it again it will probably do the same thing. What should I do?

• Are there any benefits to using a Distributed vSwitch for iSCSI?

  - by dunxd

  I am designing our vSphere farm - we'll be migrating from ESX 3.5 to 4.1. I plan to set up a new farm using ESXi 4.1, and move the Virtual Machines on the 3.5 farm into it by shutdown, then import. In ESX 3.5 there is no distributed networking, so each host has a vSwitch connected to my SAN NICs, and a port group for the vmkernel. In vSphere (ESXi 4.1) I have the extra option to set up a distributed vSwitch and distributed port groups for vmkernel to access iSCSI storage. Is there any benefit to this, or should I stick to non-distributed networking for iSCSI.

• Signal strength and Speed of wireless network

  - by Tim

  As shown by Lenovo Access Connections on my Windows 7, the wireless network I am using has a speed of 54.0Mbps but a signal strength of 88%. I am using WinSCP with unlimited speed to download files. WinSCP shows that the speed fluctuates between 100 and 120KiB/s. I was wondering what are the difference between the two speeds from Lenovo Access Connections and WinSCP? How can I tell the actual speed performance, for example, from the above measurements: speeds and the signal strength mentioned in the two places. Thanks and regards!

• Setting up Multiple Routers (as Hardware Firewalls) behind a Home Router

  - by Synetech

  I’ve currently got one computer behind a router with built-in firewall functionality, connected to a home cable-modem that has a single Ethernet port and one IP. I’m going to have to set up another computer for the rest of the family to use which of course will need to be connected to the Internet, probably wirelessly since the modem is in my room and the new system would not be. What I would like to do is to get two more small routers with firewall capability and connect each computer to a router, which would in turn connect to the main router which connects to the cable-modem. That way, both systems have a hardware firewall protecting them (particularly the wireless system) and the burden of blocking would be reduced on both the computer CPUs and the main router because the secondary routers would handle some of the workload. I’m trying to find out about the complexities inherent in this design and how I could set it up to work, specifically the IP handling and NAT aspect. Thanks a lot.

• Windows 7 Skype shifts audio to speakers

  - by Greg Reynolds

  I have noticed a strange feature on my Dell Latitude running Windows 7 and Skype. When I am listening to music on the headphones, and Skype rings, then the audio I was listening to is redirected to the computer speakers, while Skype takes over the headphones. This is infuriating as my co-workers are treated to 1 second snippets of whatever rubbish I have on at the time. Any ideas on how to stop this happening? I messed with some of the settings on Skype, but nothing seems to make any difference.

• vsftpd, virtual users and permissions. Avoid using chmod 777?

  - by Jakobud

  I am running vsftpd with Virtual Users (managed through a MySQL db). Each users home/default directory is owned by vsftpd:vsftpd. I need to give a user read/write permissions to some website files, owned by apache:apache so they can make some changes. I did a bind mount for the web directory to a directory in the ftp user's home/default directory. When logging in, the user is not able to write to the web folder, unless I set files to 777. Is it possible to set this up with making the directory and it's files 777? The web directory needs to be apache:apache in order for apache to work with it.
