• Execute script before shutting down in Ubuntu

  - by juanefren

  When I shut down my computer I want to show some pending tasks that I have to do before leaving the office... I did a local application to manage those tasks, so basically I just want to run a command, and shut down after I kill the app executed. I have already tried with these options: * /etc/gdm/PostSession/Default -- this works only when I select LogOut option instead Shutdown. * /etc/rc0.d/K01mycustomscript -- execute script after X is killed * $HOME/.bash_logout -- This looks like does nothing. * ./app-to-run && sudo shutdown -h now -- Don't like it for 2 reasons, prompts for sudo password, and can't use my laptop shutdown button. I am using Ubuntu 10.04

• Which simple server virtualization solution to use?

  - by vvanscherpenseel

  For one part of our hosting platform we are currently using VMware Server 2 to create two virtual machines on one physical machine. One VM is used for hosting of small websites, the other VM is used as a staging environment. Both the host OS and guest OSes run CentOS Linux. Support for VMWare Server 2 has been discontinued and we are currently looking for a replacement. We only use basic functionality (we don't use snapshots, moving around VMs to different physical machines, or other 'advanced' functionality'). Just a box, with two VMs. We are looking for a virtualization solution that has long-term support, is stable and allows configuration/management from Mac OSx (I understood that Xen only has a Windows client). What would be the right solution for us?

• How can I offer 2.4 ghz wi-fi in a building with strong interference?

  - by user49995

  I have a few access points on one floor of a high-rise building. They support both 2.4 ghz and 5ghz. When I used 2.4 ghz, the channel management features did not seem to work and we experienced frequent problems. When I switched to 5 ghz the problems went away. However, the 5ghz standard is much less accepted. And when clients come in, they want 2.4ghz. What can I do? How can I offer 2.4ghz wi-fi in an area with a lot of interference?

• Managing Windows 7 Workstations

  - by ethamoose

  There was a similar thread to this a few years back, but without any solutions. Just wondering if things have moved on since then. I'm primarily an Mac admin working in a college, but I have recently taken over responsibility for about 30 student workstations running Windows 7. For the Macs I have Apple Remote Desktop, where I can logon to machines in a session,check for any nefarious student activity and if necessary, log off or lock users out of machines. Could anyone give me a suggestion for an equivalent Windows system manager where I can do these tasks - e.g. not just a vnc client but one with more management options?

• strategy /insights for avoiding document content loss due to encryption

  - by pbernatchez

  I'm about to encourage a group of people to begin using S-Mime and GPG for digital signatures and encryption. I foresee a nightmare of encrypted documents which can no longer be recovered because of lost keys. The thorniest issue is archiving. The natural way to preserve privacy in an archive is to archive the encrypted document. But that opens us up to the risk of a lost key when time comes to unarchive a document, or a forgotten password. After all it will be a long way in the future. This would be equivalent to having destroyed the document. First thought is archiving keys with documents, but that still leaves the forgotten pass phrase. Archiving the passphrase too would be tantamount to archiving in the clear. No privacy. What approaches do you use? What insights can you offer on the issue?

• Laptops and Visual Studio 2010

  - by Chad

  I have three days to get a new laptop before I need one that can run Visual Studio 2010. Normally I have two instances open, an instance of SQL Management studio, IIS, and a few web browsers. Who develops regularly on one, what are the specs I should look at targeting? I haven't bought a laptop in 5 years, so I'm way out of touch with where they are at as far as specs go. Thanks. ps. Budget isn't a huge concern, but I'm trying to keep it reasonable.

  - by L.M

  I am currently in a situation where the system time of my windows machine differs 6 hours from the actual local time. I tried chaning the system time of my windows machine 6 hours back to match the actual local time. The issue is, when the system time is changed, Exchange stops working as it wont start anymore. When i change the time back Exchange works again. Here is the error that it shows when im trying to open the management console after changing the system time. The Follwing error occured while attempting to connect to the specified server "servername". The attempt to connect to http://servername/PowerShell using "Kerberos" authentication failed: Connecting to remote server failed with the following error message: Access is denied.

• Homegroup sharing problems

  - by soandos

  I can see other people in my homegroup and their folders, but when I click on those folders, I cannot see the contents (no error message, just nothing happens). The other people in the Homegroup can see me just fine, and my files In addition, I cannot see the files that they have under the network tab, though they can all see each others stuff. What could be the issue? The homegroup has already be created and recreated numerous times. Perhaps unrelated, but I am unable to turn off password protected sharing.

• Type 1 Hypervisor on the desktop

  - by Blazemore

  I have a powerful home PC, and I've used VirtualBox to run Linux distros in Windows (and vice versa). I'm interested in trying out a lightweight type 1 hypervisor to run all my operating systems (Windows 7, Debian, Arch) and was looking for suggestions of which to pick and how to implement this. From what I gather, a type 1 hypervisor is a lightweight OS which simply provides VM management functionality. Will I get reasonable performance under each guest OS? Can all the guest OSs have access to a shared data drive, or is is best to have a storage server in another guest OS and mount it over the virtual network? What about gaming, is this feasible, or will I realistically need to run Win7 on bare metal? I'd appreciate any input.

• How do I set up two existing disks with identical contents as a single mirrored volume in Windows 7 without losing data?

  - by Software Monkey

  I have two data disks that were, heretofore, in a mobo RAID configuration in Windows 7. They are now separate AHCI disks, visible in Computer Management. How to I go about making them a single mirrored volume in Windows? Note: The data is backed up up on two other separate disks, but it's a fair amount of work to do a restore (over 120'000 files, and I have to reset permissions). Note2: Currently the two disks are identical, and I can use the content of either one for this.

• sharepoint 3.0 site restore/import trouble...

  - by Trondh

  Hi, We have some old sharepoint data (from a WSS 3.0 SP1 or SP2 install), that I need to restore. Problem is: This is a time management site, and one of the fields automatically pics up the user name of the user that enters data, and this is used to keep track of who worked when. Now, when I import this into my temporary sharepoint 3.0 server, these fields are blanked, and the creator of the element is replaced by my admin user (the account that ran the import job). So, to the question: Is there any way at all to grab hold of these data before the sharepoint import job "destroys" them? I'm using stsadm -o import. I don't care if I have to pick the database itself apart manually, I just need to know if it's possible to get hold of these fields with data intact from my export files... (Backup you say? It was deleted loong ago. This sharepoint export is all we have...)

• Spotify stopped scrobbling to libre.fm - unable to login

  - by dsolimano

  I've set Spotify up to scrobble to libre.fm using the hosts file hack, as specified on the wiki, adding these two entries to my hosts file. 149.20.54.250 post.audioscrobbler.com 149.20.54.250 ws.audioscrobbler.com This worked for a while. However, Spotify now tells me that it can't log in to libre.fm. I've double checked my username and password. I haven't changed anything else. Using nslookup confirms that the above names resolve to the correct IPs. So, how do I fix this?

• "Device Not Ready" when attempting to connecting an old (DOS) hard drive to windows 7

  - by Christopher Vigliotti

  I have an old Western Digital Caviar 2540 hard drive that I am attempting to connect to a Windows 7 machine by using a Bytecc BT-300 USB 2.0 to IDE/SATA Adapter. I'm connecting things in the right order (power, then sata, then usb) and the jumper settings on the drive are at present set to slave, but am still having an issue. I am recieving a message that the drive is not initialized. When I go into Computer Management I can see the drive (as "Disk 5, Unknown, Not Initialized"), but when I attempt to initialize it or right-click and select "Offline" It tells me that "the device is not ready". Is there something that I can to to get around this, connect the drive and copy the data that I need off of this drive? Is there a third party tool available that I can use?

• What is the significance of these different width, height and resolution parameters?

  - by ??????? ???????????

  An image with a pixel resolution of 640 x 480 has additional dimension and resolution parameters according to exiftool. I'm unsure what they mean. Why are the X / Y Resolution parameters the same?Should they not reflect the pixel dimensions of the image? What does Exif Image Size mean and how is it different from the pixel dimensions? What is the focal plane? Does it have any relation to the device used to capture this image? $ exiftool evil1.jpg | egrep 'Width|Height|Resolution' X Resolution : 180 Y Resolution : 180 Resolution Unit : inches Exif Image Width : 400 Exif Image Height : 300 Focal Plane X Resolution : 8114.285714 Focal Plane Y Resolution : 8114.285714 Focal Plane Resolution Unit : inches Image Width : 640 Image Height : 480 If needed, the original image can be obtained from: here=http://www.pythonchallenge.com/pc/return/evil1.jpg wget --user=huge --password=file $here

• Yum through http proxy

  - by eodchop

  I have several Fedora 13 servers that have to connect through an http proxy for yum updates. All port 80 traffic has to be routed through this proxy. I have setup the proxy server in the network settings GUI. I can browse the internet just fine. I have also setup my proxy information in /etc/yum.conf as follows: proxy=http:proxy.largecorp.corp/accelerated_pac_base.pac proxy_user=user proxy_password=password I then added the export HTTP_PROXY="http:proxy.largecorp.corp/accelerated_pac_base.pac" to /etc/bashrc and sourced the file. When i run yum update: Loaded plugins:presto, refresh-packagekit Error: Cannot retrieve repository metadata (repomd.xml) fro repository: fedora. Please verify its path and try again. All of the repo urls are the defaults, as this is a fresh install.

• An international mobile app - Should I set up EC2 instances in multiple regions?

  - by ashiina

  I am currently trying to launch an mobile app for users around the world. It is not a spectacular launch which will get millions of users in weeks - just another individual developer releasing an app. I know enough about the techniques of managing timezones, internationalizing string, and what not ( the application layer ). But I cannot find any information on how I should manage my EC2 instances... Should I be setting up EC2 instances in different regions around the world? Is that a must-do, or is it an overkill? I'm aware that it's the ideal solution in terms of performance, but it becomes very tough managing servers in multiple regions. DB issues, AMI management, etc... I'd much rather NOT do so. So I would like to know the general best practice when launching an international app/website. Note: For static contents, I know it's better to use a CDN, so I'm planning on doing so.

• Help w/ error "Account exceeded bandwidth limits" Thunderbird 3 + Gmail

  - by boo

  Over the past two days I have been receiving the following message on a new computer running Windows 7: Account exceeded bandwidth limits. (Failure) Whenever I try to access my emails through Thunderbird, this is followed by: Login to server imap.gmail.com failed. Credentials are correct as I have access via HTTP. And then it requests me to enter my password (I have also unlocked the captcha on this account, but this didn't stop any error messages) I'm looking for a details on why this is happening, to prevent it from reoccurring, such as whether this is specific to something in Thunderbird 3 or google?

• Restrict only some plugins to specific sites in Google Chrome

  - by Christian

  I am looking for a way to set up Google Chrome so that it will run a certain plug-in (Java, what else?) only on whitelisted sites, but other plug-ins (like the PDF viewer) everywhere. From playing with the policies available for Chrome, I think there are basically two levels of plug-in management: List of disabled plugins/enabled plugins: Controls whether a plug-in exists for the browser at all This pair of policies applies to plug-ins, but not to sites. Default plug-in settings/Allow plug-ins on sites: Controls on which sites plug-ins can run This set of policies applies to sites, but not to individual plugins, and it cannot override the first pair. There appears to be no way to configure Chrome so that some plug-ins only run on whitelisted sites, but others run everywhere by default. I have also looked at filtering content on the firewall/proxy level, but I'm not convinced it can be done securely there. Filtering by URLs (file names) or content types can be circumvented trivially, and identification by content inspection cannot be safe either.

• Cannot Login as root

  - by Josh Moore

  At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.

• How do I set up my home server to go directly to a port other than 80

  - by Kevin

  I'm using dyndns, a lynksis wt54g router, and tomcat 7 with spring to set up a web server. This is my first time to attempt this. I'm sure this is a very common question, but I don't know enough to find the answer after quite a bit searching. Dyndns is successfully forwarding to my ip. The main problem is, the router admin login is coming up when my url is used. I'm hosting my site on port 8080. I have port forwarding set up for port 8080 but my request times out when I attempt to use my url like this www.myurl1234.com:8080. I don't want users to have to type the port anyway. I also tried changing the management port to 82 and hosting on port 80, but I still get the router admin login when I use my url. Where am I going wrong? Can I set it up so that www.myurl1234.com goes straight to port 8080?

• Publish database between two open database connections (Visual Studio 2005)

  - by danielswe

  I have two data locations, one to a local and one to a remote database. How do I copy the local database schema to the remote? The reason I don't use "Publish to provider" is that I'm not sure that I have all the information necessary to do so. I have the database name, server, username and pass but not "web service address" nor "web service password". I work in Visual Studio 2005. The server is a MSSQL 2005 server. I have tried using the queries but I only get errors doing so.

• Accessing SVN Repository on external drive

  - by Stephen

  I've installed SVN on my Raspberry PI and configured it to access the repository on an external hard drive. In /etc/fstab, I've have the following: //192.168.1.12/SHARE/repos /media/repos cifs sec=ntlm,username=Guest,password=,_netdev,dir_mode=0777,file_mode=0777 0 0 This mounts with no issues. When I go to add a project to the repository using the following command: sudo svn import mywebsite/ file://media/repos/mainrepository/mywebsite/ -m "Initial Upload" I get the following error: svn: E170000: Unable to connect to a repository at URL 'file://media/repos/mainrepository/mywebsite' svn: E170000: Unable to open an ra_local session to URL svn: E170000: Local URL 'file://media/repos/mainrepository/mywebsite' contains unsupported hostname The only thing I think maybe causing the issue is the file settings: drwxrwxrwx 2 root root 0 Jun 11 2009 repos As you can see the owner is root, I think it needs to be www-data, but for some reason I can't change it. Any help appreciated.

• cdrom drive doesn't work on laptop

  - by bozdoz

  Here's as best as I can describe it: When starting up, the boot order doesn't recognize the cdrom drive, but I can open and close the drive during this time. In Windows 7, I can't open the cdrom drive, and it doesn't recognize it in device manager, disk management, or my computer. In Ubuntu Linux, I can open the cdrom drive, but it still doesn't recognize the cds, and it won't mount. If I reformat everything, would my cdrom drive work again? Can I reinstall Windows without a cdrom drive? I've deleted the upper and lower filters as was suggested in Google searches. Took the disk drive out and checked that it was installed correctly (no reason it shouldn't have been). Still: nothing works.
