• No boot device found. Press any key to continue

  - by Andrew Banks

  I took out the hard drive from my Dell Latitude E5420 notebook, put in an ADATA S599 solid state drive, and installed Ubuntu 11.10. When I boot, the Dell BIOS splash screen appears with a progress bar, which quickly fills up, and the screen goes black. All of this is like it was before. At this point, the OS splash screen should fade in. Instead, I was dismayed to see simply the following, in white text on a black screen: No boot device found. Press any key to continue After looking around for the Any key (just kidding) I press a key, and the Dell BIOS splash screen appears again with a progress bar, which quickly fills up, and the screen goes black. This time, however, the Ubuntu splash screen shows up, Ubuntu opens up, and all is normal. Every time I shut down, however, this happens again. It's like a game the computer and I play together. The computer has never started up without first saying: No boot device found. Press any key to continue and it has always started up after I press any key to continue. It also starts up fine if I click Restart instead of Shut Down. Thoughts?

• Change default profile directory per group

  - by Joel Coel

  Is it possible to force windows to create profiles for members of one active directory group in a different folder from members in another active directory group? The school here uses DeepFreeze to protect public computers. In a nutshell, DeepFreeze prevents all changes to a hard drive such that every time you restart the machine the disk is identical to it was at the time you froze it. This is a bit different than restoring to an image, in that it never really wrote changes to disk in a permanent way in the first place. This has a few advantages over images: faster recover times, and it's easy to thaw the machine for a few minutes to perform maintenance such as windows updates (which can even be automated). DeepFreeze also allows you to configure a "thawspace" partition, where changes are persistent across reboots. One of the weaknesses of DeepFreeze is that you end up needing to create a new profile every time you log in, unless your profile existed at the time the machine was frozen. And even then, any changes you make to your profile while working on a frozen machine are lost. As students have frequent legitimate needs to log in to our classroom machines, there is currently a lot of cleanup involved from time to time in removing their old profiles and changes, so I want to extend DeepFreeze to protect our classroom computers as well as public computers. The problem is that faculty have a real need to keep a stateful profile locally on these classroom computers. The solution I would like to use is to configure Windows via group policy (or even manually, if that's the way I'll have to do it) to place profile folders on the thawspace partition, but only for members of the faculty security group. Is this possible?

• Adding file to /etc/cron.d doesn't make it run (ubuntu 10.04)

  - by tom

  If I scp a cron file into /etc/cron.d it doesn't run unless I edit the file and change the command. Then crond seems to pick up the cron file. How can I make cron reload its cron files in ubuntu 10.04? 'touch'ing the file doesn't work nor does 'restart cron' or 'reload cron'. My cron file is set to run every minute and logs to a file. Nothing ends up in the log file until I edit the command, and there's no entry for it in /var/log/syslog I'm stumped. Here's my cron file saved to /etc/cron.d/runscript # Runs the script every minute. This is safe because it will exit with success if it's already running * * * * * www-data if [ -f /usr/local/bin/thing ]; then exec /usr/bin/php /usr/local/bin/thing mode:prod -a 14 -d >> /var/log/thing/mything.log 2>&1; else echo `date +'[%D %T]'` "Thing not deployed. Command not run\n" >> /var/log/thing/mything.log; fi &

• ssh works fine when using public interface, but slow when using private interface

  - by Kevin M

  My Linux(UbuntuEEE) to Linux(CentOS) ssh takes a long time to log in(~15 seconds) when using the private interface, but not when using the public one. I have a Linux box acting as my router. As such, it has multiple interfaces(75.xxx.xxx.xxx, 192.168.1.1). I can ssh in from the internal interface(192.168.1.65 to .1), but it will take a while. I can ssh into the public address, and it goes quickly(~1 second). I have another box that I can ssh into the inside interface from and it goes quickly. iptables is set to accept packets coming into the interface immediately. sshd's UseDNS is normally on; I get the same problem if I turn it off and restart sshd. I normally use public-key authentication; I have done a mv ~/.ssh/ ~/ssh/ and it will ask me for a password after going slowly. After logging in(using either interface), speed is quick. ssh client version(via ssh -v):OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 ssh server version(via rpm -qv openssh_server):openssh-server-4.3p2-29.el5

• Can't Connect SQL server - process being used by another process. Conflict with IIS?

  - by shinya

  I'm having problem connecting to MS SQL Server (2012 Express) after accessing a database through IIS (web site). I can access the data through web site no problem, but I can't access the data from any other programs (i.e SSMS) until I reboot the SQL server. It seems that the connection stays open even if I close a browser. Here is error message I'm getting Unable to open the physical file "C:---------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Unable to open the physical file "C:-------". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". Cannot open user default database. Login failed.

• Error: could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit

  - by Gleeson9

  Pre-note: This is not a problem I am having with Minecraft. All answers I can find seem to be Minecraft issues. Error: could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. I get this error when I try to do something Java related. I cannot launch a .jar without this error coming up and when I try to install JDK, I get this error. This has been plauging me for a while and I was not able to research an answer so I thought I would ask it myself. EDIT: Windows 7 (x64) Dell Studio Laptop, 4GB RAM, external Radeon HD 6950 Graphics Card. I have tried uninstalling all JVMs and reinstalling but it didn't work, although I cannot remember how thorough I was so I may try again. Here is a list of all the Java related things I have installed (found in the uninstall or change programs window): Java 3D 1.5.1 Java 3D 1.5.1 (x64) Java 3D 1.5.2 Java 6 Update 30 Java 6 Update 30 (64-bit) Java 7 Update 2 Java 7 Update 3 (64-bit) JavaFX 2.0.3 (64-bit) JavaFX 2.0.3 SDK (64-bit)

• Recent DDE / file open issue with Office 2007 affecting only a few machines, is a Windows Update to blame?

  - by kafka

  All our workstations run Windows 7 Professional 64 bit. It started with one, then another, then another couple of machines having a problem accessing Word files locally and on the network. This doesn't happen on my machine though. Affected users get the error message 'There was a problem sending the command to the program'. I've Googled for solutions, but none of the answers worked. They suggested deleting certain registry keys; unregistering and reregistering the program for DDE; resetting the way that the shell opens .docx programs etc. each to no avail. As it affects local and network shares I believe the problem lies with the clients, and not the server, and I'm starting to suspect that there could have been a recent Windows Update which has caused this. I've tried comparing the updates on my working machine with an affected machine, but I can't immediately see any major differences. Has anyone else recently encountered this problem? What are the best steps to take to further isolate what could be causing this?

• Can I configure Thunderbird 3 to refresh the folder list for an Exchange IMAP account?

  - by Howiecamp

  Background: When used as an IMAP client against Gmail, Thunderbird 3 (may be the case in v2 also, not sure) will refresh it's list of folders (the folders correspond to Gmail labels) when you do "Download/Sync Now..." or restart the Thunderbird client. Any new folders (labels) created in Gmail will sync to the client and any folders moved/changed/deleted folders in Gmail will move/change/delete on the client as well. (Note: Thunderbird has the concept of "subscribing" to IMAP folders (assumingly allowing you to determine which folders you want, rather than bringing all of them down and dragging loads of data across the wire). When used against Gmail, Thunderbird appears to automatically subscribe to all folders (including when folders are newly created in Gmail), so this might be why the refresh is happening properly.) This behavior is what I want with Exchange. When using Thunderbird with Exchange (2007), the folder list doesn't refresh when folders are added/changed/deleted on the server and/or from a different mail client. When I look at the subscription options, some are checked and some are not (not sure why Thunderbird picked some and not others). And when I add new folders on the server and/or from another client, they never even appear in Thunderbird's list of folders, preventing me from subscribing to them.

• Diagnose remote desktop freezes in Windows 7 when no BSOD?

  - by Paul Smith

  Okay, I'm getting no joy from Asus or Microsoft on this, so hoping for some clues on how to narrow down the cause. I have very frequent OS freezes, always & only when running Remote Destkop Client (mstsc) in Windows 7 x64. I never have a bluescreen, and there is never a minidump. The display & input just freezes -- no keyboard, no mouse, and sound will just continue the last wavelength if any. So far, I can't find a way to trap the hang given that there's no bluescreen; advanced startup & recovery settings for system failure are "Write an event" checked, "Automatically restart" checked, and "Kernel memory dump". I've updated to the lasted BIOS, and tried a few different graphics drivers, both generic & ATI. I've also tried disabling Aero, and everything about the remote desktop experience (incrementally unchecked every box in the mstsc - options - experience tab), even disabled/unplugged external monitor to make sure it wasn't a dual-monitor issue. My specs are: Asus G73jh notebook 8GB RAM ATI Mobility Radeon HD 5800 Series graphics (recently tried driver versions 8.791.0.0, 8.801.0.0) American Megatrends G73jh.211 BIOS (7/27/2010) Windows 7 Home Premium x64 Windows Memory Diagnostic passed all of the following at least 3 times with no errors: MATS+ INVC LRAND Stride6 WMATS+ WINVC This notebook is better than most at removing heat (laudable vent design), so I'm not inclined to suspect thermal causes (especially since running 1080p video for hours has never caused a freeze, but mstsc does, reliably, within 5 minutes to an hour). This did seem to start happening after a Windows Update, but I've since reverted every patch applied since a week before the first occurrence, with no joy. (And I'd only had the PC for a couple weeks before that, so it could have been chance + less actual time spent remoting at the beginning.) I'm at my wits end, and I bought this laptop primarily as a remote terminal client (go figure, right?) Any ideas on how to identify the cause of this? Thanks!

• Is 2 GB of RAM better than 2.5 GB?

  - by pibboater

  My laptop has two slots for RAM, and currently has two 512 MB chips, for 1 GB. Windows XP is running terribly slow on it, so I want to upgrade the RAM. I could buy two 1 GB chips to replace both of the current 512 MB chips, to give me 2 GB of RAM. Or, the price is the same to buy one 2 GB chip, to replace just one of the 512 MB chips, and give me 2.5 GB total. The RAM it takes is PC2-4200 533MHz DDR2. What do you think would be better: buying two 1 GB chips so it can take advantage of dual-channel operation, or buying one 2 GB chip to end up with more total RAM but not dual-channel operation? Like I said, price is the same, so performance is the only consideration. I'm not doing anything especially intensive like video or photo editing -- just having multiple Office programs open, playing music, browsers, etc., but currently even opening the first application takes forever. If it matters, the laptop is a Toshiba Qosmio G25-AV513 running Windows XP Media Center SP3. Thanks! Kevin

• Help trying to figure out why IIS7 is crashing / locking up / denying connections

  - by Pure.Krome

  Hi folks, I've got a pretty busy website that is running on a single web front end machine, on W2K8 + IIS7. Every now and then - eg. maybe monday at 3am or something, then a few days later .. some early morning time .. then nothing for 2 weeks ... etc - the website fails to respond to any client connections. ie. no one can connect to the website. I can remote desktop to the machine, etc no probs. I restart the app pool (the website is running in intergrated mode), still nothing. I try and get a crash dump of the process (it's around 600 mb maybe even more) ... that fails after about a min of trying (and i have plenty of HD space). The only way to fix this issue, is to manually stop the www service and then start it again. The stopping takes a while (a minute?) while starting is nearly instant. I'm at a loss to figure out what part of my code is causing this. At first, I thought it might be a stack overflow because of some error that might be going to the error page, which in turn errors .. rinse repeat boom. But i've had a look at the error page and it feels ok. So, I'm hoping someone might be able to help and say how I can correctly get a proper dump of the IIS process so i can then do some more autopsy on it. I would email Tess Ferrandez (the goddess of crash debuging) but I thought I'd try here before I spam her. Can anyone have any suggestions to how I can figure out how to start to debug this issue?

• Rails application keeps timing out when attempting to connect to Postgresql DB

  - by Corillian

  I'm hosting a postgresql database on a small windows azure Ubuntu 13.04 VM with a default postgresql.conf. I have a Rails application running on a medium windows azure Ubuntu 13.04 VM. When accessing the postgresql database the rails application is constantly timing out. In its database.yml I have the connection pool size set to 120 and the timeout set to 15 seconds. Despite this my rails logs are full of the following error message: ActiveRecord::ConnectionTimeoutError: could not obtain a database connection within 5 seconds (waited 5.0023203 seconds). The max pool size is currently 120; consider increasing it. My postgresql.conf has a max connection limit of 120, making it any larger prevents the server from being able to successfully restart. I've also made sure that ssl was off in the postgresql.conf per this article but beyond that I have no idea what's going on. My postgresql logs don't contain any info indicating something is going wrong. My website is getting ~1k hits per day so perhaps a small VM instance just isn't powerful enough? I appreciate any assistance! [Edit1] The postgresql database is in a separate cloud service within the same affinity group. For example: db small VM: mydatabase.cloudapp.net (Affinity Group US East) forums medium VM: myforums.cloudapp.net (Affinity Group US East) On the database server I have opened port 5432. The connection to the database server from the forums server is using its hostname. Is it possible that the DNS resolution is what's taking so long?

• PuTTY inserts random characters during a session

  - by Zachary Polikarpus

  I recently started renting space on a remote server so that I could work on a project. I found that a relatively painless way to access it on a windows machine is through PuTTY. However, there is one thing that has always irked me when using it: for seemingly no reason random characters are sometimes inserted at the cursor. Most of the time it is just a single tilde, but rarely it spits out what looks like some escape sequence ([[^8 or the like). It will only occur when I am focused on the window, whether I am typing or 20 feet away from the keyboard. If left for long enough, it will spit tildes at random intervals (average is about 1 minute). Finally, this behavior seems to be inconsistant when running programs such as nano or the mysql interface: in nano, instead of inserting tildes, it will set marks (ctrl-^); in mysql, lines will become un-editable. My question is this: Has anyone else experienced this sort of behavior in PuTTY? And if so, what can be done to prevent/correct this behavior?

• Utility to grant admin rights to a user in Windows XP for few hours/days?

  - by user15660

  I have two accounts on my windows xp home desktop. The default regular user is used for everything and the 2nd user which has admin rights is used only for installations. I do this to avoid malware infestations during web browsing and limited user account is guarding against online threats to a good extend but many programs refuse to run under limited rights like revo uninstaller. many installs i run from limited user by selectin "run as" from right click context menu of the .exe file. but some apps need admin rights for certain. I use "switch user" to go to admin mode and do the install/uninstall. but the admin user has none of my preferences bookmarks setup nor has my locate32 indexing done and ready for fast search Is there a utility which I can use "run as" login in administration login and use that to grant my limited user admin rights for a limited amount of period like few hours or days? Please help. I guess MS might have closed many doors of it for fear of exploitation of the API. are there any?

• 403 Error when accessing vhost directive

  - by Ortix92

  I'm having some troubles with setting up my webserver (Centos 5.8). It's a brand new server and I'm trying to set a vhost to the following dir: /home/exo/public_html However whenever I restart httpd I get the following warning: Code: Starting httpd: Warning: DocumentRoot [/home/exo/public_html] does not exist Yes the directory does exist. So whenever I visit the domain exo-l.com it gives me a 403 error. This is my config file (I put this inside my httpd.conf because the files in conf.d were not included for some reason. Or at least my newly created vhost conf file, but that has 0 priority for now) <VirtualHost *:80> DocumentRoot /home/exo/public_html ServerName www.exo-l.com ServerAlias exo-l.com <Directory /home/exo/public_html> Order allow,deny Allow from all </Directory> </VirtualHost I'm completely clueless because this should work as far as I know. httpd is being run as apache:apache i tried chowning the public_html directory (also recursively) to exo:apache, apache:apache, root:root with no success. chmod 777 doesn't do anything either. a tail from the log: [Sat Oct 13 15:10:04 2012] [error] [client 82.***.***.61] (13)Permission denied: access to / denied [Sat Oct 13 15:10:04 2012] [error] [client 82.***.***.61] (13)Permission denied: access to / denied I also found something about selinux and that disabling it might help, but do I really want to do that?

• Mac OS X will only upload zero-byte files through FTP

  - by tabacitu

  I'm using Mac OS X Lion and i've been having this problem with FTP (any FTP client, mind you. I tried Transmit, FileZilla, Cyberduck and the Terminal, all with the same result) I can browse files in my FTP Client, but when I upload files, the client hangs for a few seconds, then thinks it uploaded the files successfully, but it only creates a new file with one blank line in it. Sometimes, it manages to upload 4-5 lines. It then returns: 226 - Error during read from data connection 226 Transfer aborted But 2xx is a success message. It is not a server issue, since any Windows machine will upload just fine using the same network. Can anybody figure out what the problem is? It renders my mac useless for web development. The problem persists with SFTP and FTP with SSL/TLS. Later edit: Solved! Ok, turns out the problem goes away when I take out my router and connect directly through PPPoE. So the problem is with the router, I thought. But no, the problem is with the mac that connects through a router that connects through a PPPoE and tries to upload using FTP. Pretty specific, I know. The problem is with the MTU (maximum transmission unit). Apparently, mac os x breaks the file into chunks that are too large for the router to send, because the router's MTU was set lower than Mac OS X's. My router's was 1492, which is ok, but my Mac's MTU was 1500, which is unacceptable. I don't even understand why it works directly with PPPoE. Anyway, if you encounter the same problem, this is how you diagnose and fix it: In terminal, run: ifconfig | grep mtu to see what the MTU is for en0 (or en1, mine was en0) If it's 1500, run sudo ifconfig en0 mtu 1300 This should solve it. If so, it may only be until the next restart. You can also change the MTU in System Preferences \ Network \ Ethernet - Advanced \ Hardware

• program to track recent saved files or downloads?

  - by DiegoDD

  Back to windows XP times, i used a program named Ava Find that can find any file in the system, but a really nice feature it had, called "scout bot" that automatically finds new files, that is, recently created. More info here: AvaFind For example, if i saved or downloaded a file (in any program), but i cant remember its name or where i put it, i just simply looked at the scoutbot list, and it showed me the most recent files, and then i could just open them from there, or jump to their path. Since i changed to windows 7 (passing through vista), the program no longer works. It simply keeps indexing forever and never finds anything. I don't know if it is not compatible with win 7 itself, or because the fact that my windows 7 is 64 bit. I already tried to contact the Avafind creators, but they never answered, and the program seems to be no longer supported (although the site still works). Now, is there a similar program that finds RECENT files? e.g. listing the most recently saved files, system-wide (or even limiting it to some folders, discs)? And that of course, that is confirmed to work with win 7 64 bit. I know that there are many programs that can find any file, like everything, but what i want is to find recent files and their paths, without knowing their name or e. "everything" also can sort results by date, which is almost what i need, simply to look for part of the file name or extension, and get the most recent one. but if i get to many results, it takes a while, plus, i STILL need to know the name or at least extension of the file. What i want is simply a "Most recently Saved files" tool. i.e., a replacement for Scout Bot in Ava Find. Do you know any alternative?

• How to resolve 'No internet connectivity issues' with a Virtualised 2008 R2 Server using Forefront UAG

  - by user684589

  I have spent some considerable time reading up on as many possible blogs and articles as I can to help me solve why my VM (Running on Hyper-V) for DirectAccess has suddenly stopped being able to access the internet. The VM setup shares the same internet connection on which I have written and submitted this question so I know that the actual underlying internet connection is fully functional. Previous to last week the DirectAccess was fully functional and had no issues. This is a recent problem which was led up to by a number of consistent crashes on the DA machine when access was attempted. Upon reboot all seemed well until recently. I am not certain whether it is relevant, but previously to this I had a number of power issues where the entire VM host shutdown unexpectedly leaving around 8 VM's in a bad way. Upon restart, the UAG DirectAccess machine was unable to access its configuration service (although the service was started) but this seemed to relate to the Light-Weight Active Directory Service AD LDS which had a corrupted database. Having repaired this database, I restarted the service and could subsequently reconnect to the configuration service again. For good measure I re-bound the network adapters (virtualised through Hyper-V) and DirectAccess claimed to be all happy again. However as it stands my machine is still unable to access the internet showing the "No internet connectivity" exclamation mark for the external facing NIC. I have also tried removing the adapters, disabling, re-enabling and the problem persists. The intranet part of the VM CorpNet seems to be fully functional as before and I'm running out of ideas. Any input would be greatly appreciated. I am not an advanced Domain Administrator so please be gentle.

• Is there an objective way to measure slowness of PC/WINDOWS?

  - by ekms

  We've a lot of users that usually complain about that his PC is "slow". (we use win XP). We usually check startup programs, virus, fragmentation, disk health and common problems that causes slowness (Symantec AV drops disk to 1mb/s , or a seagate HD firmware error in certain models), but in those cases the slowness is pretty evident. In other hand, the most common is the user complaining about his pc but for us looks OK, even in 6 years old desktops. People sometimes even complains about his new quad core desktops speed!!! So, we are asking if there's a way to OBJECTIVELY check that a computer didn't dropped its performance, compared with similar ones o previous measures, specially for work use (I don't think that 3dmark benchmark o similar may help). The only thing that I found that was useful is HDTune, but it only check hard disk performance. Basically, what we want is something that enable us to say to our users "see? your PC is as slow as was three years ago! stop complaining! Is all in your head!"

• Windows 7 System File Checker (sfc) not working

  - by Andrew

  I have a strange problem with Windows 7 RTM. I'm running Ultimate 64-bit edition. Whenever I run sfc /scannow I get this error: Windows Resource Protection could not start the repair service. My research so far has told me that I need to set the Windows Module Installer and Windows Installer services' startup types to Manual. They already were, so I manually started those services and tried again. No luck. I've even booted into my Windows 7 repair disc and tried running sfc /scannow from that. All I get is this: A repair operation is already pending. Restart and try again. History: I'm trying to run sfc because I am unable to open any images in Windows Photo Viewer. Whenever I try, I get the error "Class not registered." I believe the problem started after I installed Gladinet, but I can't be sure. I've uninstalled Gladinet, but the problem remains. System Restore was disabled (yes, I know I'm stupid - you don't have to remind me). Please help. Thanks.

• nginx logrotate config

  - by TomOP

  Whats the best way to rotate nginx logfiles? In my opinion, I should create a file "nginx" in /etc/logrotate.d/ and fill it with the following code and do a /etc/init.d/syslog restart after that. This would be my config (I havn't tested it yet): /usr/local/nginx/logs/*.log { #rotate the logfile(s) daily daily # adds extension like YYYYMMDD instead of simply adding a number dateext # If log file is missing, go on to next one without issuing an error msg missingok # Save logfiles for the last 49 days rotate 49 # Old versions of log files are compressed with gzip compress # Postpone compression of the previous log file to the next rotation cycle delaycompress # Do not rotate the log if it is empty notifempty # create mode owner group create 644 nginx nginx #after logfile is rotated and nginx.pid exists, send the USR1 signal postrotate [ ! -f /usr/local/nginx/logs/nginx.pid ] || kill -USR1 `cat /usr/local/nginx/logs/nginx.pid` endscript } I have both the access.log and error.log files in /usr/local/nginx/logs/ and want to rotate both daily. Can anyone please tell me if "dateext" is correct? I want the log filename to be something like "access.log-2010-12-04". One more thing: Can I do the log rotation every day on a specific time (e.g. 11 pm)? If so, how? Thanks.

• OS X won't boot up unless I hold down option key

  - by Gazzer

  I have a strange issue on an early 2008 Mac Pro running OS 10.6: if I restart the computer it restarts normally if I shutdown and boot, it stops at the grey screen just before the boot process if I shutdown and boot but hold down the option key, I can select the boot disk and all is good. I've just cloned the disk, and the same thing happens. The disk is a SAMSUNG HD154UI The disk is partitioned (the second partition holds a clone of the Snow Leopard Install disk) One weird thing on the original disk was one of the partitions said 'EFI Boot' in a non-aliased font rather than the name of the disk when the disks are listed upon holding down option. Solution: it seems that there was a problem with the disk. Part of the difficulty in finding the solution was that you need to remove the disk from the computer completely. For example, a good disk in Bay 3, wouldn't boot up if the bad disk was in Bay 2. So for ages I thought the problem was hardware related in Bay 3. So if you think you have a dodgy disk remove it totally if you are testing the hardware with a 'clean' disk. Cleaning the PRAM helped to get the new disk to work too.
