• cannot log in to all account except guest after mounting new partition

  - by student

  I really really need help. to do my homework from school, since two days ago, I was installing oracle 11g on my ubuntu. through that process, there was lots of problems also, but searching a lot, in somehow I could go to the next phase installing it. (because it was the first time to install on ubuntu by myself..) but when I was making password for oracle and clicked next, it says there are not enough space for home/oracle folder, So to make another space, I mounted another space after checking Gparted and using Software device management, I mounted it. And when I rebooted it, since then, I cannot log in to my own administrator account and even to oracle account(that I made for oracle 11g on ubuntu ) when I type the passwords for it, it seems to work but it redisplay the first page to log in, without really logging in it.. So I loggined to here as guest account... and even I cannot try gnome console manipulation to restore or fix it.. because it is guest account... I`m struggling for three days and... help me, how do I need to do? and at the time oracle said it needs enough space for its home folder, how I should have done?

• ALT+TAB doesn't work properly in Windows 8.1

  - by Marco1

  Holding ALT+TAB will activate the flip 2D to switch from a window to another. The problem is that this function remains active for a very short time and I'm not able to select the window I want in the foreground. I also noticed that when I put the cursor on an icon on the taskbar, the live preview thumbnail disappears quickly. With a safe mode restart the problem is no longer there, all is fine! With a clean install of Windows 8.1(no driver and applications installed) the problem is here again; obviously disappears with a safe mode restart also in this situation. What's the problem? A Windows process or service?

• Move entire OS from NTFS drive to bigger ext4 drive.

  - by pangel

  According to SMART data, the hard drive I curently use is about to fail. I bought a new, bigger drive to copy the system to a safer place. The old drive is 160GB. Ubuntu was installed with Wubi, and the partition is NTFS. There are a few other partitions around (recovery partition, swap...) that I don't care about. The new drive is 320GB. I would like the new system to run on ext4, not on NTFS. I looked at solutions that use dd, or clonezilla, but it seems that moving to a different filesystem prevents me from using them. I considered installing a brand new ubuntu on the new hard drive and then copy /home from the old drive to the new drive, but I heard that there would be file permission problems. I would also have to reinstall all my software. One last thing: the NTFS drive has dead sectors. I don't know how this can influence the copy process, but I mention it just in case. edit: I do not care about the windows partition. I just want Ubuntu to make the transition.

• Hosting solution for startup social app?

  - by happyhardik

  We are in a process of building up a social app. Initially we will have only a few thousands of users than will grow with time. Which would be the best and suitable hosting for this purpose? Grid, cloud or VPS? (it has to be economic, as we are just starting up) The hosting needs to be strong, so, in case our app has increase in the user base all of a sudden it wont break up or slow down the app. Our app is in PHP, MySQL. Sorry, if question posted in wrong place. Thanks, for your time. :)

• SQL Server 2005 transactional replication break before a configured number of retries

  - by ti2

  We have a SQL Server 2000 Standard database with some tables being replicated (continuous transactional replication) to dozens of SQL Server 2005 Express and MSDE computers. The step 2 of the replication agent job (Run agent) is configured by default to retry every 1 minute for 10 times if some problem ocurr. Because the client machines get shut down at night (they are POS machines), we changed the number of retries to 5760 (4 days), so replication would not be broken at night and would not need to be restarted manually. But the problem is that every other day we have at least one machine with broken replication, with this error: The process could not connect to Subscriber 'POS986'. NOTE: The step was retried the requested number of times (5760) without succeeding. The step failed. It seems that SQL Server is not respecting the number of retries or the interval between retries as we configured. PS: I have restarted the replication job after changing the number of retries from 10 to 5760.

• "Access denied" to C:\Documents and Settings after removing malware?

  - by Rising Star

  My Windows 7 PC became infected with the so-called "Malware Protection designed to protect" trojan while I was at work the other day. I managed to kill the process so that the malware is no longer running. The removal instructions specify to delete the following file: c:\documents and settings\all users\application data\defender.exe However, when I click to c:\documents and settings, it says "Access denied". Prior to this malware infection, I've never had any trouble accessing "Documents and Settings" or "Application Data." I read that in Windows 7, c:\documents and settings is a psudonym for c:\users, but I still cannot find the file defender.exe. Suggestions?

• Is there a Linux mail server with an outgoing pickup directory?

  - by Paul D'Ambra

  On my Exchange server I can drop appropriately formatted text files in the "pickup" directory and Exchange will process them. I'd like to split this bulk mailing functionality onto another box to protect our business mail IP from the bumpy ride that our monthly newsletter gives us. I should note at this point that the mailing is opt-in with an opt out link included and only goes to people who pay to be a member of our organisation The ideal solution for me would be to add a linux box to use just for this purpose so we're not paying for Exchange licenses. So is there a linux equivalent of the Exchange pickup directory?

• Programmatically closing a dialog box - win32 [migrated]

  - by user1697579

  I'm working on an application to detect a pop-up dialog and then automatically dismiss it. I'm writing this as a C++/Win32 app. The dialog box is generated by IE 7 and I can detect the window, but several methods to get the OK button to "click" have failed. Doing searches for other people's solutions, sending these messages to the button handle seems to have worked in a lot of situations: PostMessage( handle, WM_LBUTTONDOWN, 0, 0 ); PostMessage( handle, WM_LBUTTONUP, 0, 0 ); PostMessage( handle, BM_SETSTATE, 1, 0 ); It has no effect on the button state in my tests though. I can send tab characters to the main window and see that the OK button gets focus, but then sending return characters does nothing. To learn more about this I used Spy++ to get information about the window hierarchy and what messages are delievered when I manually click the OK button. Looking at the message log and reading about WM_MOUSEACTIVATE seamed to offer a solution. The log info shows that 0002166C was the button window. So in my code I tried this: GetClassNameA( handle, str, str_size ); if( strcmp( str, "Internet Explorer_Server" ) != 0 ) return TRUE; // Not the window we're interested in. // Send a message to activate the button window and have it process a mouse click. PostMessage( handle, WM_MOUSEACTIVATE, (WPARAM) dialog_handle, MAKELPARAM( HTCLIENT, WM_LBUTTONDOWN ); Based on the window hierarchy and message log, I think the window with the class name "Internet Explorer_Server" is the button. Maybe I'm wrong, because it does seem like an odd class name for a button... Below is a link to the window hierarchy image, message log when I manually click the OK button. Last is the code that's executed on a 1 second timer ticket, looking for the window. Any insight and help is appreciated! Image of the window hierarchy, source, window messages, and test dialog source are available here: https://sites.google.com/site/matthewmillersmiscellanea/Home/

• Scale an image with unscalable parts

  - by Uko

  Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the aspect ratio in order to fit some view-port. The tricky part is that the text is not scalable only the picture(s). The distance between text and the image is still relative to the whole image, but the text size is always a constant. Example: let's assume that our total composition is two times larger than a view-port. Then we can just scale it by 1/2. But because the text parts are a fixed font size, they will become larger than we expect and won't fit in the view-port. One option I can think of is an iterative process where we repeatedly scale our composition until the delta between it and the view-port satisfies some precision. But this algorithm is quite costly as it involves working with the graphics and the image may be composed of a lot of components which will lead to a lot of matrix computations. What's more, this solution seems to be hard to debug, extend, etc. Are there any other approaches to solving this scaling problem?

• Mac OS 10.7 Missing Java Completely

  - by Stuartsoft

  I'm in dire straights. I was trying to replace my java JDK and downgrade to 1.6 and somehow managed to completely screw up all the previous versions in the process. Bottom line, my Mac has no JDK installed at all. I've tried reinstalling java 1.7 from Oracle, I've tried using Pacifist to manually extract the files from the 1.6 Apple Java... nothing. When I open terminal and use java -version all I get is -bash: java: command not found My real goal is just to get back to java 1.7, but even after running the installer, java is still inaccessible to terminal and other applications.

• Find RARs with duplicate content

  - by Scott McClenning

  I need a utility to find RAR files that contain duplicate data (i.e. files within the RAR that hash the same, but could have different names). I can open the RARs and see the CRCs are the same, but I was hoping for a more automated process that would work in bulk (hundreds of files). Hashing the overall RAR won't help because the file contained within could have different names, or the archive could be compressed at different levels. If needed, a utility that would extract the contents of the RARs and then compare would work, but is not preferred. I would prefer a free utility for Windows, but a pay utility or a utility for Linux would be acceptable.

• What is the procedure to replace a failing hard drive in a RAID array?

  - by slayton

  3 years ago a co-worker setup a software RAID-6 array on Ubuntu 9.04 and I'm getting messages from the OS that the drive has bad sectors and should be replaced. I'd like to remove this drive and replace it with a new drive, however, I have never done this before and I'm terrified that in the process of fixing the array I'm going to end up ruining it. I know the device ID of the array and I know the device IDs of the individual drives in the array. Additionally I physically have the bad drive. What are the steps to replace the bad drive with a new drive and get the array running again?

• How Can I Automate the Backup of a Quickbooks Server?

  - by Nick

  I have three computers: The first is the company file server which has the Quick Books company file, is always on, and lives in the closet. The other two are Quick Books Clients. All are XP Pro. I need a way to automatically backup the QB data file, without any user intervention. Quick Books has a built in scheduled backup utility, but from what I've read, it only works when the software is running in single user mode. (and obviously putting the server into single user mode defeats the concept of having a server). Also, I'm not actually running QB itself on the server, just the "QB Database Server" process that sits in the system tray. Surely there must be a way to automate this? I'm open to any ideas/suggestions. Thanks!

• Is there a difference in page fault rates between CPU bound and I/O bound processes?

  - by user198864

  I was thinking, should there be any difference in expectation of the page fault rate on CPU-bound vs I/O bound processes? At first I thought maybe we could, since CPU-bound processes would likely be using more memory accesses per time quantum, so I expect it would move from locality to locality faster. At the same time, the CPU-bound process is probably given a larger working set... but this doesn't affect the fault overhead as it hits a new locality IF this wasn't pre-paged in. Is there actually any real difference in the page fault rates or am I just musing about something nonexistent? And if there is, how would it impact a real-world OS like linux?

• Has anyone seen an HTTP 500 error when HTTPS traffic going through Pound Proxy forwards to an HTTP page?

  - by scientastic

  We have Varnish as our load balancer and reverse proxy cache for normal HTTP traffic. For HTTPS traffic, we use Pound proxy to unwrap the SSL and forward to Varnish, which then forwards to the back-end servers. This is used for our "checkout" process to encrypt credit card info in transition. However, on the last stage of checkout, users are always getting an HTTP 500 (Internal Server) error. It doesn't seem to be due to our back-end app server, by all tests I've tried. Does anyone know anything about how that transition works-- the transition back from HTTPS to HTTP and the interaction between Pound and Varnish-- and why it might cause 500 errors?

  Im getting an error half way through an SQL Server 2008 r2 installation. The error states Not all privileges or groups referenced are assigned to the caller. it asks to retry or cancel. Upon trying both, the error message returns and I must cntrl-alt-delete to end the process. I have checked all permissions associated with local account, network domain account and ran installation as administrator. I have searched on the web and other people are having this problem too but I cant find a solution. so I turn to the experts, anyone encounter this error??

• How to move a selcection of files into a new folder via the right click menu?

  - by LinuxDudester

  I recently switch from OSX to Xubuntu 14.04 and I'm loving my new found freedom. For the most part I've managed to customize my Linux operating system to my needs and likes. But theres one feature I'm missing the most. I need to toss a bunch of items in a folder really fast, since I am working with lots of images and text files. In OS X there was a nifty shortcut that manages the operation in one fell swoop so you don't have to make a folder and then take further action to populate it. All I needed to is to select the items I want in the Finder (file manager), right-click on them to bring up OS X's contextual menu, and choose the first option: New Folder with Selection. The Finder will then create a new folder with those items stored safely inside, removing at least one step from the process for you automatically. Super easy! Now I was wondering how can I do this in Linux? Or most importantly in Xubuntu? Any help would be greatly appreciated!

• Utilising a Magento server cluster to drive hot reindexing

  - by WOBenji

  We've asked a similar question in the past, basically we have a very large Magento store with 500000 products which are currently reindexed once a day, during the night. We'd like to speed this process up significantly, we're at about 4-5 hours now. The solution was suggested for us to do something like this on a server cluster and replicate the database changes after they've been done on a machine that isn't being bothered with serving customers. But what is the mechanism for that? How do we replicate those changes across to the live site from the server cluster? Can someone point me in the right direction here?

• enable tcp_syncookies even after reboot

  - by Tim

  I'm running Scientific Linux 6.1 and would like to set net.ipv4.tcp_syncookies=1. I've set that in /etc/sysctl.conf and, if I do a sysctl -p then sysctl -q net.ipv4.tcp_syncookies it shows it's properly set. Sadly, if I reboot the machine, and sysctl -q again, it goes back to 0. I've tried to grep around and see if something else is resetting it to 0 during the boot process but haven't turned up anything. I've googled and everything points to sysctl.conf. The only thing I can think of is maybe networking isn't up by the time that file gets read but, honestly, I'm a developer and well beyond my natural skills here:) I'm tempted to just set it directly in /etc/init.d/network but then that feels hackish and so, I thought better of it and I'm here in search of the "right" way to do it. Any pointers?

• Unix / linux permissions setup for shared hosting with Apache

  - by weiyin

  I'm in the process of setting up a server from a clean CentOS 5 install. What is the best permission structure (users, groups, unix permissions) for running a single instance of apache for multiple users? Ideally, it should satisfy these requirements: Each user's websites are stored in a subdirectory of their home directory. Users can edit files and permissions. Apache can read the websites of all users. No user can read the website files of other users. Bonus question: how to add PHP and/or Perl and/or Ruby to Apache without allowing any users to access any other user's files?

• Recommendation for hardware upgrade: thin clients? Or...?

  - by Alex C.

  I work for an animal shelter in Upstate New York. We have about 50 machines running XP Pro. They're connected to a Windows network with a domain. About half of these computers are used for nothing more than using two web-based apps -- one to keep track of our animals, the other to process credit cards. Having a full-blown desktop PC seems like overkill for this purpose. The PCs are three-to-five years old, and I'd like to come up with a plan to upgrade the hardware. Our donations are down (not surprising, given the economy), so cost is a big factor. Can people recommend some options? Some sort of thin client, maybe?

• Why would an ext3 filsystem be rolled back on a Debian VM running in VirtualBox after loss of power to the host

  - by Sevas

  A Debian Virtual machine runs as a Guest VirtualBox VM. It's filesystem is EXT3. The host system loses power and after booting up the host system and guest VM, I find that the VM's filesystem has been rolled back to a previous state, losing changes made to the filesystem some time before losing power. The operations that were rolled back had been fully completed before the loss of power (files fully copied, file handles closed, etc.), but it's possible and even likely that other write operations were occuring on the VM at the point of the crash. So I am trying to figure out if it's the filesystem recovery process that rolls back filesystem operations after encountering corruption post power loss, or is it possibly related to VirtualBox and the way it ignores flush requests for performance gains by default (discussed here) Are there any other factors that would result in the filesystem being rolled back after losing power?
