• Does this mean the router is faulty?

  - by Ashfame

  I have a router to which I have my desktop (running Ubuntu) connected via LAN & I use it on my phone via wifi. Sometimes it happen that the LAN one will stop working for no reason but the wifi will work fine. And it will resolve away by itself. Since last night, the router was restarting again & again on its own, so I lodged a complaint about it and they said the router is faulty and will be replaced, but I know they don't know anything about how things work & is just going to shoot an arrow in the dark. These restarts has happened for the first time, LAN-wifi issue described earlier is a common one (but not frequent one). So is the router faulty or there is some issue from my ISP side which will continue to persist even after they change the router? My very best guess is that they will replace it with an older refurbished router which will tend to give me more troubles in the coming time, so its better if I change it only its faulty (this is a new one - 6months old, I am its first hand user). I am happy to provide any details.

• How to scan multiple pages from a book under Linux?

  - by rumtscho

  I want the process to look like: I choose the correct scan settings (dpi, color depth, etc) I lay the first page on the scanner and trigger the process The scanner scans the page and waits for me to position the next page correctly I confirm that the next page is ready for scanning Repeat the above two steps until I tell the scanner that there are no more pages to come The scanner saves everything into a single PDF. I tried both xsane and gscan2pdf. First problem: they want me to know how many pages will be scanned. This is already a nuisance, but I can do the counting if needed. The main problem is that in step 3, the scanner does not pause. It is probably optimised for being fed loose sheets. The next scan process is triggered automatically as soon as the CCD has returned to the start position. The time the scanner needs to return the CCD is very short and I can't turn the page and position the book properly. Is there a software which can do the scan process in the way I described above, or did I just miss a setting available in xsane or gscan2pdf to make the scanner pause? If it makes any difference, the scanner is an Epson Stylus SX620FW, I run it using the manufacturer-provided driver.

• Moving hidden files/folders with the command-line or batch-file

  - by Synetech

  Question Does anyone know of a way to move files and folders that have the hidden, system, or read-only attribute set from the command-line or a batch file? (No, stripping the attributes first is not an option since there is no practical way to know which attributes were set in order to re-set them after the move.) (Failed) Attempts Using the basic move command does not work with items with the hidden or system attribute set and for some reason, it does not have switches to specify attributes like the dir and del commands do. I tried using a utility I wrote that uses the shell’s file operation function, but that requires using start /w to prevent the batch file from running on ahead, and it complains about long-filename support for some reason. I tried using robocopy, but it first copies the files and then deletes the originals instead of simply moving the source (which results in a frustrating delay, even with the excessive output redirected to nul). (Surprisingly it seems that few people have ever needed to move hidden files from the command-line. All I could find was this one person who abandoned the attempt.)

• XCOPY access denied error on My Documents folder

  - by Ryan M.

  Here's the situation. We have a file server set up at \fileserver\ that has a folder for every user at \fileserver\users\first.last I'm running an xcopy command to backup the My Documents folder from their computer to their personal folder. The command I'm running is: xcopy "C:\Users\%username%\My Documents\*" "\\fileserver\users\%username%\My Documents" /D /E /O /Y /I I've been silently running this script at login without the users knowing, just so I can get it to work before telling them what it does. After I discovered it wasn't working, I manually ran the batch script that executes the xcopy command on one of their computers and get an access denied error. I then logged into a test account on my own computer and got the same error. I checked all the permissions for the share and security and they're set to how I want them. I can manually browse to that folder and create new files. I can drag and drop items into the \fileserver\users\first.last location and it works great. So I try something else to try and find the source of the access denied problem. I ran an xcopy command to copy the My Documents folder to a different location on the same machine and I still got the access denied error! So xcopy seems to be denied access when it tries to copy the My Documents folder. Any suggestions on how I can get this working? Anyone know the reason behind the access denied error?

• How to route between 2 networks with a server with 2 network cards?

  - by LumenAlbum

  This is the first time I am faced with routing and it seems I have hit a dead end. I have the following scenario: client1: 192.168.1.10 255.255.255.0 gateway: 192.168.1.100 DNS server: 192.168.1.100 client2: 192.168.1.20 255.255.255.0 gateway: 192.168.1.100 DNS server: 192.168.1.100 server (Windows Server 2008 R2 with enabled RAS & Routing Services) network card 1 (connected to a switch along with the clients) 192.168.1.100 255.255.255.0 DNS server: 127.0.0.1 network card 2 (connected to the router) 192.168.2.100 255.255.255.0 gateway: 192.168.2.1 DNS server: 127.0.0.1 (DNS forwarding to 192.168.2.1) ISP router (with connection to internet) 192.168.2.1 Now in this scenario I have tried to route traffic from the 192.168.1.0/24 network with the clients to the 192.168.2.0/24 network with the routers to connect them to the internet. However, no matter what I do I get no positive ping to the router 192.168.2.1. Ping from 192.168.168.1.10 to 192.168.1.20: Success to 192.168.1.100: Success to 192.168.2.100: Success to 192.168.2.1: not reachable The routing table contains the 2 routes 192.168.1.0 and 192.168.2.0 as directly connected. Does anyone know where the routing fails? I have searched different forums but mostly found nothing relevant. One post however pointed out that in a similar situation the problem was that the router doesn't know the way back and the internet router would need a static route back to the first router. If that really is the case, I take it there is no solution with my equipment, because the standart ISP router doesn't allow to set any static routes.

• why does my computer crash?

  - by chobo2

  Hi my computer keeps crashing and I don't know why. At first I thought because I had my cpu over clocked that it all of sudden was crashing. So I set my cpu back to regular speed. This did not help. I then thought it was because 2 sticks of my memory where from a computer that suffered from a power surge. However I just ran the windows memory diagnostic tool( extended) and after like 6 hours of testing my memory it found no errors. So now the only thing that is left is windows 7 64bit. I first over clocked my cpu for a couple months while running XP. Never had a problem. I installed the memory and windows 7 at the same time. But I not sure if it is my memory now since it passed the diagnostic tests. However I am not sure if it is windows 7 either has I installed it twice in the last year. I really don't want to go back to XP to find out if this is the case. So here are my blue screens of deaths(from bluescreen). https://sites.google.com/site/myerrorswin7/errors (I hope you enjoy my great site lol) As you can see most of them are different NTFS_FILE_SYSTEM KMODE_EXCEPTION_NOT_HANDLED BAD_POOL_HEADER IRQL_NOT_LESS_OR_EQUAL SYSTEM_THREAD_EXCEPTION_NOT_HANDLED SYSTEM_SERVICE_EXCEPTION

• Booting Ubuntu as VM with KVM on Ubuntu 12.04

  - by CrazycodeMonkey

  I am trying to boot my very first VM using KVM. I have Ubuntu 12.04 installed, i made sure the BIOS had the right virtualization flag enabled for intel processor by running kvm-ok. I have researched this on google and all the instructions that i have found so far are outdated. for e.g. most instructions talk about booting a virtual machine with the following commands qemu-img create -f qcow2 foo.img 100G --- create a virtual disk for your VM kvm --name foo -m 1024 -hda foo.img -cdrom whatever.iso -boot d -- This runs kvm. This command line is incomplete. First you need to be root to run this. Second- it is missing option for the video device. When you run this command you get the following error "Could not initialize SDL(No available video device) - exiting" Googled this error and looked it up on stackover flow http://stackoverflow.com/questions/4841908/sdl-init-failure-reason-is-no-available-video-device The answer provided here does not work on Ubuntu 12.04 Googled this problem further and found out that i need to specify a video device so I finally ran the following command sudo kvm --name mymachine -m 8096 -hda myimage.img --cdrom ubuntu.iso -boot d -vga cirruss -k en-us -vmc :0 This was after I had created the myimage.img image on the drive. Now this command does not give me an error but it just hangs. Does anyone have clear instructions on how to run a VM using KVM on Ubuntu?

• I get "An error occurred while Windows was synchronizing with [name of time server]." when trying t

  - by ChrisF

  Prompted by the answers to this question I decided to give the Windows built in time synchronisation another go. However, no matter what time server I use I get this error: "An error occurred while Windows was synchronizing with [name of time server]." The help suggests the following as reasons for failure: You are not connected to the Internet. Establish an Internet connection before you attempt to synchronize your clock. Your personal or network firewall prevents clock synchronization. Most corporate and organizational firewalls will block time synchronization, as do some personal firewalls. Home users should read the firewall documentation for information about unblocking network time protocol (NTP). You should be able to synchronize your clock if you switch to Windows Firewall. The Internet time server is too busy or is temporarily unavailable. If this is the case, try synchronizing your clock later, or update it manually by double-clicking the clock on the taskbar. You can also try using a different time server. The time shown on your computer is too different from the current time on the Internet time server. Internet time servers might not synchronize your clock if your computer's time is off by more than 15 hours. To synchronize the time properly, ensure that the date and time settings are set close to your current time in the Date and Time Properties in Control Panel. Now the first reason is clearly wrong - I am connected to the internet. I can see the 2nd being the most likely cause. I have Sygate Personal Firewall running, but it normally asks if something it trying to connect for the first time. Does anyone know I can unblock the NTP protocol - or at least check if it is blocked?. I don't think it's #3 or #4 as I've tried a number of different servers including the one currently used by Atomic Clock Sync. Though if someone knows the address of a UK time server I can double check this.

• Suspending/Screen Going Off When Still In Use (Ubuntu & Arch)

  - by luke

  I have a laptop (HP Pavilion G6) that was running Ubuntu and for a while now (at least 6 months) has been having a problems randomly suspending whilst still in use with a full battery and still being charged. Originally the problem was with Ubuntu so I first attempted to disable suspend using every way I could find (gui settings + dconf editor) this didn't work and it still kept suspending so I ended up switching to Arch Linux. Unfortunately not long after switching to Arch Linux I ended up experiencing the same problems. So yet again I modified the settings in /etc/systemd/logind.conf to prevent it from suspending and this time it worked, kind of. Now I am experiencing the screen going off and I have to change to a different tty (by using ctrl-alt-fx, which was something I also found I had to do sometimes when waking up from suspend in Ubuntu) to get the screen to go back on. The strange thing is this only happens when running a Linux distros and only occasionally (e.g. it may happen once/twice a week at most). But when it does happen it can happen multiple times in a row. And it only seems to happen when I am using it. This may just mean that it hasn't happened yet when I am not but generally if I leave it to run something or play a video it hasn't occurred only when I am using it regardless of which program I am using (e.g. it has occurred when using firefox, vim, even when using a virtualbox vm). At first I thought it could be the CPU temperature but after monitoring it I discovered it occurred a lot of the time when my CPU was less than 50 °C. I then checked /var/log/* but could not see anything related to it suspending only a few standard things from when it was woken up. I am really out of ideas and really hoping someone can help. Thanks in advance.

• Exchange 2007 - Mailbox Database Recovery

  - by Phrontiste

  Exchange 2007 edb Can we restore Exchange edb (First storage group\mailbox database.edb) to another exchange server ? Do I just copy the edb to the new exchange server and delete the first storage group\mailbox database.edb and replace it with this one ? How can I get all the mailboxes from that (old) mailbox database.edb ? I had a exchange 2007 server with 10 mailboxes, I have installed exchange on another machine and was thinking if I can do the above ? or is there any way I can get all the mailboxes from that edb (old mailbox database) and import them into the new one. I have deleted the old exchange install I had (these are test machines) What are the steps required to get the DB working on the new machine ? Also, I am confused about the recovery storage group ? I can mount a mailbox database in recovery storage group, but when I try to get mailbox out of it, it won't match any thing ? can someone please assist in understanding RSG and how to restore the OLD mailbox database. thanks and regards Phrontiste

• Router startup problem

  - by gfmoz

  I have problems with my Tilgin Vood Router. As I try to start my router by turning the power on (captain obvious), it generally doesn't work the first 3-4 times. This is getting very annoying. Five minutes after turning the power on the router's signal LEDs don't blink in the way they should do in a connected state. I can connect to my routers web configuration interface through my PC connected to it via LAN though I can't access the internet. It usually takes the router five minutes to get to the point where it should be connected to the internet but as it doesn't work the first times. So I turn on my router 3-5 times, let him work 5 minutes and then suddenly, after turning the pow*emphasized text*er off and on again it all works. The problem is regarding startup only, when I get it to work everything runs as smooth as a 1980-s text-based C++ game on a 3ghz machine. I also have to restart my PC too in order for everything to work. - How can I solve this problem? - Just leave the router turned on all time? I prefer a daily IP switch, though. - May the problem have something to do with my PC? There is another one connected to the router too and it doesn't work there either.

• Reference entire excel 2007 sheet to another sheet

  - by Keikoku

  I have one sheet with 100 rows of data. I have a second sheet that will use the same data but with filters applied. In fact, I will have a dozen sheets, each with different filters. My goal is to have references from the every sheet to the first so that prior to filtering, they all contain exactly the same data. This way I only have to modify one sheet and all sheets will reflect the changes. The purpose is to create external links from word to excel to display specific rows, but there appears to be a limitation to linking where it displays absolutely everything that you see on the sheet itself (and each view must be different). I can manually reference the first cell and then drag the black box to easily expand it to the required number of rows, but that would require me to go into each sheet and drag the black box again whenever I add new entries to the master copy. Is there an easy way to do this? Note that the issue is the same as Easy way for users to update linked documents Excel 2007, except this time I am using a different approach. Solutions to both would be welcome.

• windows 7 turns off itself everyday at about 9am

  - by Radek

  I was given this comp at work and after a week or so this strange thing started to happen in the middle of doing something :-( It turns off itself at about 9.10am every morning Just once a day and it works fine after it had it little nap. it happens both if the comp was on all night or I turned it off before leaving the office. I tried to swapped the memory as I was told that there was an issue with memory. But moving or removing any memory did not make any difference. I am not aware that I would install any program that could cause that. I installed AVG and set it up to do every day scan about 8am + if restart is needed it requires user confirmation. 'The Software Protection service has stopped' few minutes before it turned off itself but it happened also at other times without the computer turned off. I turned off Windows automatic updates as the first thing when I got the comp configuration Windows 7 Ultimate Intel Core2 Quad Q9550 at 2.8GH, 8GB RAM ST31000528AS Barracuda 7200.12 SATA 3Gb/s 1TB Update Below message are logged when I turn the comp on again.

• Compressing and copying large files on Windows Server?

  - by Aaron

  I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

• Can not boot windows XP from cloned hard disk - what can I do?

  - by Martin

  My configuration: a PC (some years old) with MSI K8N-Neo-4F Motherboard, 1 GB RAM. Disk 1 (Maxtor, SATA II, 250 GB): 2 Partitions, on Partition 1 (48 GB): Windows XP Professional (NTFS) on Partition 2 (190 GB): data (NTFS) I wanted to have a larger and faster disk (the PC is incredibly slow and permanently the disk is rattling when I try to open an application or during Windows startup), so I took Disk 2 (Seagate, Sata II, 500 GB), installed in the PC, created at first a 400 GB-partition at the end of the disk and cloned the data to it, which worked well Installed a swap partition and a partition for Ubuntu Linux 12.10 on the first "part" of the disk so I was able to boot Linux and the old Windows XP with the Linux "System selection" at startup. Now I wanted to move Windows XP to the new disk, deleted the Linux partitions cloned Windows XP to the new disk (with free tools - EASESUS), left both disks in the PC and tried to select the new hard drive during boot as boot partition. This did not work, the PC refused to boot from this second disk. I tried many things like making the boot partition on the 2nd drive "active" in the Windows System Preferences modifying the boot.ini file to boot from the second disk - tried to boot from it, but ended with an error message stating that it was not possible to boot from this disk because of a hardware failure or something else or so removing the original disk and plugging the new one on the same SATA port as the original one - also booting failed with an error message repairing the MBR by booting into recovery mode from the Windows XP Installation CD-ROM, selecting the second disk and doing "FIXMBR" which said that everything was fine with the MBR. after that at least the PC tried to boot from the newer disk and then startup was hanging during the blue screen with the Windows Logo.... no luck. ... deleting the cloned partition and cloning again - this time with Macrium Reflect Free version... - no success during booting. I tried a lot of things with no success, so I wonder what I am doing wrong?! What could I do to successfully clone my Win XP partition to replace the original disk by a larger one which is bootable.

• How to avoid sshfs freezing?

  - by Andreas Hagen

  So the issue is this: I've installed sshfs on Ubuntu 12.04 and I'm trying to connect to a couple of remote servers. So initially the mount seams successful. Sometimes Gnome even picks it up and displays the "new device found" box at the bottom of the screen. but from here on there is not much that works. Or at least not any more. The first couple of times i connected it seamed to work fine, and I was able to transfer some files, then i disconnected using fusermount -u <folder> and after reconnecting a little later the trouble started. Now after executing sshfs -o ServerAliveInterval=15 -o reconnect -C -o workaround=all -o idmap=user root@<host>:/ <folder>, when I change directory into the mount-point, the shell just freezes. Strangely ls -al <folder> works when listing just the root of the remote system, but nothing more. Also every file-explorer I've tried freezes just like cd <folder>. To me it seamed like there was some kind of zombie thread or something hanging around my system, due to the fact that it did work the first time, so I have tried rebooting but no luck. sshfs -V gives this: SSHFS version 2.3 FUSE library version: 2.8.6 fusermount version: 2.8.6 using FUSE kernel interface version 7.12 So yea, any ideas?

• Recommended Win2k8 Server software to fix my RAID-0 issue

  - by Jason Kealey

  I'm running an Asus P6T V2 Deluxe. It has six SATA ports and supports onboard RAID. I am using two of those ports for a RAID0 array of 1.5TB Seagate drives using the onboard RAID controller. One of them is giving me SMART warnings and I want to preemptively replace it. I pulled out two other 1.5TB drives from another computer and am ready to use one or both, if necessary. I can't run any SMART diagnostic software from within Windows because it only sees the hardware RAID-0 array, not each individual drive. The first thing I tried was a slow sector-by-sector copy using a free tool called EASEUS Disk Copy. Used the bootdisk, copied (took like 16 hours), unplugged the defective drive and plugged the new one in its place. The motherboard didn't recognize the new drive as being part of the known setup, so it did not want to boot. The second thing I tried was using other software (I forget the name) to copy the partition from within Windows. The first software failed because I had a server operating system. I found another software (I forget the name) which supported a server OS and did a partition copy onto the new drive. This seemed to work and the OS started to boot, but blue screened and started a reboot cycle. I'm assuming the software I was using was no good as it was trying to copy the boot disk while it was in use. I am looking for recommendations on what software to use to fix my problem without doing a re-install. Everything is backed up but my computer works fine and I'd like to avoid re-installation when possible. However, my system would be back up now if I had just started over on a second RAID array. :)

• Who should I run mysql as, on a personal computer?

  - by user664833

  I just installed mysql via homebrew (with brew install mysql, on Mac OS X Mountain Lion - recently installed from scratch). Following the installation, there is a "caveats" section with options around further necessary actions to take: ==> Caveats Set up databases to run AS YOUR USER ACCOUNT with: unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp To set up base tables in another folder, or use a different user to run mysqld, view the help for mysqld_install_db: mysql_install_db --help and view the MySQL documentation: * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html To run as, for instance, user "mysql", you may need to `sudo`: sudo mysql_install_db ...options... Start mysqld manually with: mysql.server start Note: if this fails, you probably forgot to run the first two steps up above A "/etc/my.cnf" from another install may interfere with a Homebrew-built server starting up correctly. To connect: mysql -uroot To launch on startup: * if this is your first install: mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist * if this is an upgrade and you already have the homebrew.mxcl.mysql.plist loaded: launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist You may also need to edit the plist to use the correct "UserName". On previous versions of Mac OS X I ran mysql as mysql user, but now I am confronted by the idea of running it as myself. I am the only one who uses this computer (which happens to be my laptop), and I do programming for work and for pleasure. What are the pros & cons, or best practices, around choosing whether to run mysql AS YOUR USER ACCOUNT or as mysql or something else still?

• How do I count the times each number appears in columns of numbers?

  - by Andy C.

  I am sure this must be easy, but I am inexperienced. About the best way to think of my problem is to think of it as trying to sort and then count lottery numbers. To stay simple, let's do a Pick 3 game. Let's look at 10 drawings. I would split each drawn number into a separate column: DATE BALL#1 BALL#2 BALL#3 3/1 1 3 5 3/2 3 7 8 3/3 2 2 1 3/4 5 7 6 3/5 2 3 1 3/6 0 5 9 3/7 3 7 0 3/8 6 8 4 3/9 2 4 3 3/10 7 1 2 I would like to be able to build formulas into cells that would tell me how many times each number appeared overall, and how many times each number appeared in the position it occurred. Like this (using the above example): Number Overall Count Ball#1 Count Ball#2 Count Ball#3 Count 0 2 1 0 1 1 4 1 1 2 (That is, The number zero appears twice overall, and came up once as the first number drawn; zero times as the middle ball; and once as the third ball. Likewise, the number 1 was drawn four times in our 10-day period. It was the first ball once, the second ball once and the third ball twice.) And so on. All help appreciated. I have access to Excel and Microsoft Works, or of course if there is a Google Docs way to handle this All thanks for any help.

• Http-Only cookies in WebLogic: what versions support them/how and why are they supported?

  - by John

  We want to make all cookies set by our webapp http-only. I only have a basic understanding of the benefits of doing this but I'm told by security people that it's a Good Thing (tm) Our app is running under JDK1.6.05 and WebLogic10.3.0 After way too much digging around Oracle's website for documentation, I've found good evidence that the first version of WebLogic to support http-only cookies is 10.3.1. By "support," I mean the cookie-http-only deployment-descriptor element. Before we go about upgrading, I'd be nice to have these questions answered: 1a) Is it accurate that WL10.3.1 is the first version to support http-only cookies and that we're out of luck with 10.3.0? 1b) If we do indeed need to upgrade, is there an easy to do so under Windows? I've heard people mention an "upgrade jar" that you just stick in the classpath but I can't find any mention of this by Oracle. Does an easy way exist, or do we need to do a full-install of the new version? 2) What does the cookie-http-only deployment-descriptor element do when enabled? Will it ensure all cookies set by the application have an http-only=true attribute? Will it do more or less? Is there anything I'll have to do programmatically? 3) Is there anything in general I should know about http-only cookies, getting my web app to take advantage of them, or other security concerns?

• Strange sound behavior

  - by caarlos0

  First of all, sorry for the tittle. English isn't my native language, and I can't find a word to describe the strange behavior I'm getting here. In the most simple explanation, is like sound keeps going down and up again... Think in a kid with that old radios that have a circled volume button. Think like these kid keeps "turning" the volume button. That is the behavior I'm getting here. At first, I believed that it was a pulseaudio issue, but, it isn't. I followed the wiki part I think that should be my problem, but it didn't work. After that, as I'm using XFCE, I didn't really need pulseaudio, so I removed it and stays with a clean alsa, hopping that will fix my problem. Sweet mistake. It really looks like a kid looking for trouble. I believed it worked, and, suddenly, here is the same issue again. BTW: I have a full-upgraded testing system (yeah, I upgraded to testing hopping for new pulseaudio version which fix the issue), no pulseaudio at all, just xfce, started with startxfce. What can I do to fix this? It's extremely annoying... sometimes I just want to throw my laptop in the wall because of this. Any extra info you need, please, tell me. Thanks in advance -- EDIT: My alsamixer is like this: And here is a video with the sound behavior.

• Partition is missing in /dev

  - by haimg

  I'm having a strange problem since I moved from Centos5 to Centos6. I have three disks, first two are used as a RAID1, and third one is a stand-alone backup disk that is not listed in /etc/fstab (it is mounded when needed and then unmounted). My problem: After a boot, /dev/sdc exists but /dev/sdc1 does not. Also, the links in /dev/disks are also absent for the first partition of sdc. Disk itself is fine, and if I hot-remove it and plug it back in, /dev/sdc1 appears ok and everything is working. My question: What subsystem manages auto-discovery of disks, partitions, etc. during the boot process (e.g. what creates /dev/disks/by-label)? How do I configure it to scan /dev/sdc too and create all relevant files and links in /dev ? Edit: Here's the relevant part of dmesg output (the only place sdc appears). It does list sdc1, but it's not in /dev! sd 1:0:0:0: [sdb] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 3:0:0:0: [sdc] 976773168 512-byte logical blocks: (500 GB/465 GiB) sd 1:0:0:0: [sdb] Write Protect is off sd 1:0:0:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 3:0:0:0: [sdc] Write Protect is off sd 3:0:0:0: [sdc] Mode Sense: 00 3a 00 00 sd 3:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: sdc: sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: DMAR:[DMA Read] Request device [00:1e.0] fault addr 361bc000 DMAR:[fault reason 06] PTE Read access is not set sdb1 sdb2 sdb3 sdc1 sda1 sd 1:0:0:0: [sdb] Attached SCSI disk sd 3:0:0:0: [sdc] Attached SCSI disk sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk

• Create image (EBS AMI) takes forever - possibly caused MySQL Server to break?

  - by fuzzybee

  I'm trying to create an EBS AMI from my running EC2 instance to reuse my LAMP fully configured (for my needs). I got my website up and running yesterday on this EC2 instance my MySQL was working fine until this morning (it's not that difficult to install LAMP thanks to yum so I can't see how I could go wrong with this; having said that, it's always difficult for one to realise his own errors) I have seen "Loading, please wait ..." for a few hours now. How do I know whether this is completed or its progress? Shortly after I tried to create the AMI image from my EC2 instance, I encountered database connection error can't connect to local mysql server through socket '/var/lib/mysql/mysql.sock' I was able to restart mysqld at first. But database connection was down again. This time, I could not restart mysqld anymore. It shows MySQL Daemon failed to start. Could my attempt to create the AMI by any chance cause the MySQL server to reboot or corrupt? I did a lot of searched and have done the following although I think I shouldn't have to do any workaround for MySQL server to work here chown -R mysql.mysql /var/lib/mysql/ I also found this workaround but I'm very reluctant to follow due to my belief and the fact I would need to understand this problem first. Any help would be greatly appreciated. Getting back to searching for a solution for the MySQL server problem ... Thanks, Eric
