• Installing drivers and getting -> Error Code 28

  - by Adrov

  I've recently upgraded mainboard, without reinstalling OS, so I guess that's the issue. I really don't want to install OS at this moment. Issue is I can't install USB drivers, if I right-click uninstall, just installs same driver, which isn't working ofc. and giving error code 28. I fixed such issue once long long time ago, with editing registry, but I really can't remember what and where I have to do, so if anyone know please let me know, I'm also open to all other solutions to this issue. http://i.stack.imgur.com/AuBtB.png

• Getting "is not a valid mailbox" when email sent to primary address

  - by Juan Tarquino

  Anyone outside my domain who sends me an email is getting a bounced email with the following error from Exchange: 550 550 5.1.1 [email protected] is not a valid mailbox (state 14). I can't receive emails from external addresses until I send an email to one of my secondary addresses. Once I sent it to my secondary address, my primary address will start working for a while and fail again after a few hours. We use Exchange 2003. Anyone has any suggestions on what to try?

• Amazon EC2 Sign In

  - by Barry

  When I change the home directory of my Amazon EC2 instance from /home/ubuntu to /home/ubuntu/folder in the /etc/passwd file, I am no longer able to access the instance using my existing keypair. Once I switch it back to the original directory I have no problems and can log into my instance as normal. I have checked the permissions on the new folder and they are drwxr-xr-x, which is the same the /home/ubuntu folder. I have a number of instances running at the minute and because of this change I have no way of logging back into them to rectify the situation. Does anyone have an idea what is going on? Thanks in advance

• nginx block URI request but allow internal directory

  - by Mike Anders

  I'm new to nginx from apache. I'm trying to simply block the URIs: /_mydir/* = / (redirect) But, I want to rewrite: /ex/(.*)$ = /_mydir/$1 I have tried: location /ex/ { rewrite ^/ex/(.*)$ /_mydir/$1 last; } location /_mydir { rewrite ^/_mydir/(.*)$ http://$http_host/ redirect; } But what always happens is once I block the '/_mydir' directory the rewrite is also blocked. I have also tried: location /_mydir/ { internal; } This also ends up blocking the rewrite. All help is greatly appreciated, thanks. UPDATE: I fixed this problem using: rewrite ^/ex/(.*)$ /_mydir/$1 break;

• Help with Abstract Factory Pattern

  - by brazc0re

  I need help with a abstract factory pattern design. This question is a continuation of: Design help with parallel process I am really confused where I should be initializing all of the settings for each type of medium (ex: RS232, TCP/IP, etc). Attached is the drawing on how I am setting up the pattern: As shown, when a medium is created, each medium imposes a ICreateMedium interface. I would assume that the Create() method also create the proper object, such as SerialPort serialPort = new SerialPort("COM1", baud); however, TCPIPMedium would have an issue with the interface because it wouldn't need to initialize a serial port object. I know I am doing something majorly wrong here. I just can't figure it out and have been stuck for a while. What I also get confused on show the interface IMedium will get access to the communication object once it is created so it can write out the appropriate byte[] packet. Any guidance would be greatly appreciated. My main goal is to have the Communicator class spit a packet out without caring which type of medium is active.

• Why can't I install MySQL on my computer?

  - by Bea

  I have read a lot of tutorials, but I am still having problems. What I tried: I downloaded mysql-5.5.9-winx64. All that I read says that I can run Setup.exe, but there is no such file in the download. The other option I know there is, is including \mysql-5.5.9-winx64\bin in the PATH variable and then trying to execute the mysql command. When I do that, the error I get is: ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061) I then downloaded mysql-5.5.9-winx64.msi, which is easier to install, but once I followed the instructions and it was installed, I got the same error executing the mysql command. How can I use MySQL? EDIT: I've now removed everything I installed, and I want to start from scratch.

• Apache has no rights to unzip file uploaded by DirectAdmin created FTP user

  - by FlyOn

  I know similar things have been asked a thousandfold, but I can't seem to figure it out.. I have recently started renting a VPS. It runs DirectAdmin. I created a reseller account in the admin account, and created a new user (with FTP account) with the reseller account. I logged in with FTP as the created user and uploaded a zip file and a php file which will extract the zip. But when running the script in the browser I get "Permission denied" errors however. Probably because Apache is not in the same group as the users FTP account. Now my question is: How can I solve this once and for all, so that I don't have to do it again for every new user account I create through DirectAdmin?

• Windows 7 Explorer - Activate mouse focus to be able to scroll in tree and file view?

  - by none

  I'd like to be able to scroll in the tree view without having to click in it. Is there a way to do this? I have once used a tool that generally gives focus to the window underneath the mouse cursor, but this caused some other glitches so I would like to achieve this without an extra tool. I also think that there are programs that embed the Windows Explorer and offer more features, including the behaviour I would like to have. But maybe a registry value change is all that is needed?

• Why does an ampersand in URL cause failure of some command in Mac OS X Terminal?

  - by congliu

  Why does an ampersand in URL cause failure of the following command? I want to open a web page by running Safari in Terminal, placing the URL as an argument. This works as expected: open -a safari "http://endic.naver.com/search.nhn?sLn=en&searchOption=all&query=good" But once the quotes being removed, it wouldn't work as expected: open -a safari http://endic.naver.com/search.nhn?sLn=en&searchOption=all&query=good Instead, it returns: [3] 5395 [4] 5396 [1] Done open -a safari http://endic.naver.com/search.nhn?sLn=en [2] Done searchOption=all Seems like ampersand in the URL was treated as "running previous command in the background", though there is no space following the ampersand in the URL.

• searchd under runit continues writing to the runit's log

Everything works fine, seachd starts and responds to the queries. But how to make logs to be less repetitive? When I start Sphinx manually it prints the "precached 9 indexes" just once.

• Smoothwall: How to stop live network traffic displayed in terminal?

  - by Jakobud

  For our network we are working on building a new firewall box and we just installed Smoothwall on it to test it out. When I start up the box, before the login prompt even appears, all of the live IP traffic is appearing in the terminal (source/destination IPs, MACs, Ports, etc). I wait for the boot sequence to finish, but all I see is this IP traffic. The login prompt never comes up. I finally get sick of waiting and press CTRL + C and it says "Entering Run Level 3" and then I get a login prompt finally. Once I login, the IP traffic continues to fly through the terminal even as I'm trying to type commands. How do I turn this stuff off? Is this the default setting for Smoothwall to have all this IP traffic going by on the screen? It essentially renders using the terminal to being useless.

• Incremental search in Visual Studio

  - by Jalpesh P. Vadgama

  Visual studio is a Great IDE and there are still lots of feature that not known to developers. Incremental search is one of them. This is a amazing feature to find code in particular document and its available from Visual Studio 2010 and carried over in Visual Studio 2012. Incremental search allows developers to search in document without blocking UI and allow to search as they type. Interesting!! right.. So let’s open visual studio and see how it works. Once you open Visual Studio and press Ctrl + I and type something it will find the string without blocking your visual studio UI. Just like following. In the above code you can see that, I have typed Cons and You can see that whole console word is highlighted. Even you can see that find dialog box on top right corner of visual studio 2012 like following. Same way if you see the footer in visual studio where it is finding cons in current document like following. Isn’t that great now we find things very easily and we don’t have to remember whole word like Console. Hope you like it. Stay tuned for more updates.

• How can I restore my Acer Aspire one GNU version 1.98 to factory settings?

  - by user100380

  Requires keyring and authentication to install and unistall programs or update anything. I just want to restart from scratch so i can clean it up anyways. Can anyone help? Also, on start up a list on a black screen will come up saying Ubuntu with linux version 26.32-40 generic or recovery version and at the bottom of different versions has one Window 7 loader option. When I get into recovery menu to try and restore to factory settings my netbook has no restore option. I've tried pressing alt-f10 and holding alt and repeatedly tap f10 but nothing seems to work, and my acer asks for a password login to even load windows 7 which I don't have. Any ideas? I've looked a lot on the internet for help but I'm getting to my last resort, to get of this thing for once and for all. I want to be able to personalize and add programs as I please, this is all bs to go through to unistall one freaking game or get rid of ubuntu gnome keyring!! Please help!! Thank you. :)

• Is there a software in windows that enables you to boot from a specific partition?

  - by Tono Nam

  I use acronis true image to mount images to my primary partition and it works great. lets say I have 3 partitions on my hard disk and all of them each is 600 GB. In the 3rd partition I keep files (documents, pictures etc), on the first partition is my primary partition where the operating system runs (windows 7). And in the 2nd partition is empty. I have an image of my primary partition and I save that image in my 3rd partition (50 GB is the size of the image so it fits in the partition number 3) and in an external hard drive. I know it is possible to install a new operating system in partition 2 such as windows xp but the only problem is that once I install that how could I tell the computer to boot from partition 1? is there a way to switch back and forth just like it's possible in the mac?

• Script/scheduled task to clean up Dowloads folder (Windows 7)?

  - by Andrew

  My downloads folder is my primary connection to the internet (and thus the world), and has rapidly become a virtual junk drawer. I imagine I'm not alone here. What I'd like to do is have some sort of a script that -creates a new folder (named YYYY_MM Archive so it sorts nicely) -takes everything* inside of the Downloads folder (for the current user) -moves it to the new folder and have this run once/month. *(excluding previous archives) This strikes me as the type of thing Saw some answers on related questions that seemed to suggest that this is an eminently doable task in PowerShell. Is it? I'm on Windows 7 Enterprise.

  Hi, I have a sony vaio laptop(VGN-FW31J) running windows Vista Home Premium . I've had it over a year and file upload in a browser has never worked on any website in any browser(IE, Firefox, Chrome). I can select a file and the upload starts running but I always get a timeout. Sometimes it has worked once out of many attempts but only if the file is very small( < 50k). FTP does work. I've tried the following: Disabling anti virus Disabling firewall Can anyone help me here? i'm wondering if this is a vista problem or a vaio problem. Cheers

• Sync Linux to Windows 2003/2008 Natively

  - by user26753

  Without using any external packages for Windows, can Linux synchronise it's clock to a Windows 03/08 Server natively? I've tried it using various NTP packages for Windows but would like to use just Windows software for this. EDIT: I've tried the below however it doesn't work. I've put TimeSource in /etc/hosts, stated server TimeSource in /etc/ntp.conf however when I do a service ntpd start it doesn't sync (it's 3 minutes out at the minute). I then stopped the NTPD and did a ntpdate TimeSource, thinking it would sync and then I'd start the NTPD once it's got the time, and it says: no server suitable for synchronization found. Though I can ping it. Any thoughts?

• Fastest security check of file tree on NFS

  - by fungs

  I am currently experiencing very bad performance using the following on an NFS network folder: time find . | while read f; do test -L "$f" && f=$(readlink -m $f); grp="$(stat -c %G $f)"; perm="$(stat -c %A $f)"; done Question 1) Within the loop permissions are checked using the variables grp and perm. Is there a way to lower the amount of disc I/O for these kind of checks over the network (e.g. read all meta data at once using find)? Question 2) It seems like the NFS isn't tuned very well, the same operation on a similar network link via SSHFS take only one third of the time. All parameters are auto-negotiated. Any suggestions?

• How to combine with openvpn, dynamic-ip?

  - by asfasdv

  Dear everyone, I am currently using openvpn to surf online to bypass censorship. Let me show you the initial scenario: before openvpn is turned on: IP: 1.2.3.4 (hypothetical, checked by visiting whatismyip.com/) after openvpn is turned on IP: 10.2.3.4 (this is also checked with whatismyip.com/, I assume this is where the vpn's exit point's IP ) Situation: Once I enable openvpn, I can still ssh into this computer by sshing into 1.2.3.4, even though visiting whatismyip.com/ says it's 10.2.3.4. However, I am on dynamic IP, I run a website, and am using tools (inadyn in particular) which pings the freedns.afraid.org (my dns server) and updates my ip. The messed up part is when inadyn does so, my dns changes the ip to 10.2.3.4, which is presumably the exit point of my vpn. How do I get around this? (Note that sshing into 1.2.3.4 STILL works).

• Should I install an AV product on my domain controllers?

  - by mhud

  Should I run a server-specific antivirus, regular antivirus, or no antivirus at all on my servers, particularly my Domain Controllers? Here's some background about why I'm asking this question: I've never questioned that antivirus software should be running on all windows machines, period. Lately I've had some obscure Active Directory related issues that I have tracked down to antivirus software running on our domain controllers. The specific issue was that Symantec Endpoint Protection was running on all domain controllers. Occasionally, our Exchange server triggered a false-positive in Symantec's "Network Threat Protection" on each DC in sequence. After exhausting access to all DCs, Exchange began refusing requests, presumably because it could not communicate with any Global Catalog servers or perform any authentication. Outages would last about ten minutes at a time, and would occur once every few days. It took a long time to isolate the problem because it was not easily reproducible and generally investigation was done after the issue resolved itself.

• Any freeware/ideas for getting Windows 2008's backups to dump to tape after backing up to disk?

  - by TheCleaner

  I have a Windows 2008 R2 server that is being backed up to an external ISCSI drive nightly. The problem is, we'd like to use our Tape Drive (VXA 320) that Windows sees just fine to take those backups in the "WindowsImageBackup" folder and dump them to tape once a month so that we can at least have something offsite. I really don't want to go through the hassle of licensing BackupExec or similar if possible. All I'm really after is some kind of copy utility that can copy the "WindowsImageBackup" folder over to the tape drive. Ideas? P.S. If by doing this it wouldn't matter for a restore regardless, then let me know, but I would assume I could copy the folder back over to the server and then have Windows Backup find it again.

• At what point does caching become necessary for a web application?

  - by Zaemz

  I'm considering the architecture for a web application. It's going to be a single page application that updates itself whenever the user selects different information on several forms that are available that are on the page. I was thinking that it shouldn't be good to rely on the user's browser to correctly interpret the information and update the view, so I'll send the user's choices to the server, and then get the data, send it back to the browser, and update the view. There's a table with 10,000 or so rows in a MySQL database that's going to be accessed pretty often, like once every 5-30 seconds for each user. I'm expecting 200-300 concurrent users at one time. I've read that a well designed relational database with simple queries are nothing for a RDBMS to handle, really, but I would still like to keep things quick for the client. Should this even be a concern for me at the moment? At what point would it be helpful to start using a separate caching service like Memcached or Redis, or would it even be necessary? I know that MySQL caches popular queries and the results, would this suffice?
