• All Tasks..Advanced Operations option missing from Certificaces MMC Snap-In

  - by JohnFx

  I am trying to follow the instructions in this article to create a custom certificate to support SSL on a web server. I'm stick on the following step: Click on Personal – All Tasks – Advanced Operations – Create Custom request The problem is that on the web server (Windows Server 2003 R2) I don't have an "Advanced Operations" option under "All Tasks". I do on my desktop machine (Windows 7), but not on the server. All the documentation I can find indicates that it should be available on WS-2003-R2, but it just isn't. Note: I'm going through this manual process because I need to specify a alternate host names in the CSR, which you can't do through the IIS 6.0 console certificate managment functionality. Any suggestions for how to make this option show up?

• Change Linux Console's Default Monitor

  - by Tim M

  Is there any way to specify which monitor the console is displayed on in Linux? Details: I have a 3 monitor setup with 2 video cards. When I boot the computer, the BIOS displays on the PCI graphics card (which has a small monitor). When starting Linux, the console is displayed on the same monitor. Is there a way to have the console output on a different monitor? I'm using the vesafb framebuffer. I don't see a way in my BIOS to change the default video card.

• Why does the command forfiles list files that are not a day old despite the command being otherwise?

  - by PeanutsMonkey

  The command I am executing is forfiles -p"C:\testdata" -m*.* -d-1 -c"cmd /c echo @PATH\@FILE" I have specified that I wish to only list files that are a day old however when I execute the statement, it returns me a list of files that were created today. Why is that? Am I doing something wrong? Would it be better to specify a time period as opposed to a date e.g. 24 hours? The version of forfiles I have reads as follows FORFILES v 1.1 - [email protected] - 4/98. The batch file is being run on Windows XP.

• Pin same app multiple times in Windows 7

  - by Mr. Shiny and New ??

  I use some programs with command line arguments and like to have shortcuts for launching those programs with those arguments. For example, I keep several Firefox profiles around and like to specify the profile name on the command line. Similarly I have several Eclipse shortcuts with a command line argument specifying the workspace to open. I would like to be able to pin these shortcuts to the start menu or taskbar in Windows 7. The problem I have is that once I've pinned one of these, no other shortcuts which launch the same exe can be launched. I'm also open to suggestions such as a suitable desktop gadget which can contain a bunch of arbitrary shortcuts, yet remain in a fixed position on my desktop somewhere, or some way of adding a secondary taskbar (this was possible in XP).

• Is it secure to store the cert/key on a private AMI?

  - by Phillip Oldham

  Are there any major security implications to bundling a private AMI which contains the private key/certificate & environment variables? For resiliency I'm creating an EC2 image which should be able to boot and configure itself without any intervention. After boot it will attempt to: Attach & mount specific EBS volume(s) Associate a specific Elastic IP Start issuing backups of the EBS volume(s) to S3 However, to do this it will need the private key/pem files and will need certain environment variables to be available on start-up. Since this is a private AMI I'm wondering if it will be "safe" to store these variables/files directly in the image so that I don't need to specify any user-data information and can therefore start a new instance remotely (from my iPhone, if needed) should the instance be terminated for any reason.

• Where to put unix sockets

  - by James Willson

  I am new to this, so sorry if its obvious. I am running a debian server and installing the likes of UWSGI, NGinx etc on there. The configurations keep talking about pointing to "sockets". In the build options I seem to be able to specify where the sockets for each program go. By default it looks like most of them go in /tmp/ (not all of them). Is this a good place for them to go? Im trying to keep things as organised as possible but just bunging them in my tmp directory doesnt seem like the best option.

• Annoying Search Behavior - Search Companion

  - by DavidStein

  I'm running Windows XP Professional, and ever since the last service pack I've had a searching problem. When I want to search a network drive, I get the following message: This folder is not indexed. To search this directory plase use Search Companion or add this directory to your index via options. Basically, I have two questions. Is there some way that I can use the indexed search where appropriate and then have it switch over to the Search Companion automatically? Second, how does a programmer look at this code and think this is a good idea? I realize that this question is rhetorical. However, I must enter my search string into one search, receive the error, and then click "Search Companion" to bring up the new search window. This window doesn't even take the defaults from the previous one so I have to specify the search string and drive again.

• How to access a site in IIS with no DNS mapping

  - by CiccioMiami

  In my IIS 7.5 hosted in a Windows Server 2008 R2 I have several websites with no DNS address assigned. Let's take for instance the site (as named in IIS) with site name mySite. I have for this site the standard binding with no host name. Suppose that my server IP address is, for instance, 101.22.23.01. Therefore it seems logic to me that in order to access the website, I should place in the address bar of my browser: [IP_address]/[sitename] in this case: 101.22.23.01/mySite but it does not work. Shall I specify something else in the bindings?

• rsnapshot intervals in configuration file...

  - by Patrick

  A simple question about rsnapshot. In order to perform daily backups I'm going to add lines to cron in my Ubuntu. Then, why do I have also these lines in the rsnapshot.conf ? ######################################### # BACKUP INTERVALS # # Must be unique and in ascending order # # i.e. hourly, daily, weekly, etc. # ######################################### interval hourly 6 interval daily 7 interval weekly 4 #interval monthly 3 If I use cron, should I disable them ? thanks ps. I've just realized that in the crontab I still have "hourly" and "daily". Should I then uncomment only the one I use in the crontab ? And what's the point to specify hourly if it is already specified in cron ? I'm a bit confused. # crontab -e 0 */4 * * * /usr/local/bin/rsnapshot hourly 30 23 * * * /usr/local/bin/rsnapshot daily

• How to completely remove MySQL from Windows?

  - by Nathan Long

  (I realize there are similarly-titled questions, but this one is really 'how do I reset the password', and this one doesn't specify an OS and has only gotten Linux-oriented answers.) On Windows XP, I just uninstalled MySQL and deleted the folder that it was installed in. I then rebooted and reinstalled MySQL. When it comes back up, it still has the databases it had before the uninstall. Where did it keep that database info? How do I completely remove MySQL and start over, as if I'd never installed it?

• Can I make Firefox ignore/interpret font sizes specified in pixels?

  - by Andy

  Hi all, I have an 11.1" notebook display with 1366x768 resolution, which gives it a DPI of 141. I'm running GNOME and have configured the DPI. Everything works OK except web browsing - far too many websites specify their font sizes in pixels, which ends up with very small text on a high DPI display. My ideal solution would be for Firefox to interpret an absolute pixel size in terms of normal DPI and display it appropriately for my DPI (eg scale it by 141/96). Obviously this would cause problems on the occasion where graphics had been pixel-aligned with fonts in some way, but I imagine that would cause me far less of a headache than either reading minute text, or scaling the text manually each time. Any suggestions? TIA, Andy

• Virtual Network Printer

  - by user113720

  I'm pretty new to Microsoft Servers so don't blame me if the question isn't that smart [I'm a Unix guy]. I need to install a Virtual Printer of a Microsoft Server 2008 r2. The requirements are: The printer must print on a file {whatever file... txt or pdf } The printer must run on a server The printer must accept plaintext from a specific IP:port The connection between the device that prints and the server is a local network I've tried to install a virtual printer, but I cannot specify the constraint about the socket from which receive data to print. Thank you so much

• estimating size of reply HTTP headers

  - by Guanidene

  I am trying to download a file via a basic socket connection, using a HTTP GET request. So, I have to specify how many bytes of data coming in I have to read from the socket. However, I am having trouble deciding the amount of data (say, in bytes) the server would reply back with. I know that there is a "Content-Length" field in the reply sent by server, but that gives me the size of the actual data (without the http headers). Is there a way to get the exact size of HTTP headers sent by the server or an estimation is required? (I am doing this for downloading on a mobile network, where every bit of data matters in terms of time and money, so I don't wish to make an unnecessary larger estimate of the header size.)

• Force Windows 8 to search indexed files

  - by Hrvoje

  When using search files in Windows 8 (win+f) I don't get expected results. For example, I installed VLC, it's in Program Files (86) folder, and that folder is selected for indexing. Search for files (win+f) gives 0 results. If I pin to start that exe, then it's found - but I don't want to do this, that's not the point. Where does it search for files? Is there any way to specify search locations? It doesn't use Indexing Options settings, at least it seams so. Also, searching from explorer window is kinda slow - I tried entering VLC.EXE in search box (when in c:\ root), and it takes some time to give correct results. It works, but it looks like it doesn't use indexing, rather scan all files/folders, which is slow.

• How to bulk mail-enable contacts from AD in Exchange 2007?

  - by George Hewitt

  We have several thousand 'contacts' setup in AD already for a faxing system. We're migrating to an online fax provider that uses e-mail rather than plain old telephone. So, we've bulk edited all the AD records so that the 'mail' attribute is populated with the right e-mail address in the right format. Now, how do we enable these contacts within Exchange 2007? I've looked through http://technet.microsoft.com/en-us/library/bb684891.aspx but that only seems to talk about manually editing the CSV output to specify the external addresses. AD already knows the external e-mail addresses - I just need the info in Exchange! Any thoughts?

• Findstr not finding file when searching by extension

  - by feiht thief

  I am experiencing some odd behaviour when using findstr to search a collection of .php files. Depending on how I specify the file list, the file is not being found, even though it contains the string in question. These two files contain the string "personemail": Content.php and People.php A) Works as expected (finds personemail in Content.php and People.php) findstr /i /s /c:"personemail" * B) Fails (finds only in Content.php) - expected to find in Content.php and People.php findstr /i /s /c:"personemail" *.php C) Works as expected (finds in People.php): findstr /i /s /c:"personemail" p*.php What is going on?

• Overriding RPM public key database

  - by pilcrow

  Can rpm be persuaded to import and fetch public keys from an arbitrary pubkey database? On the same build machine I've got two automated users who each need to verify package signatures from different sources, signed under different keys. If I rpm --import pkg-source1.pub pkg-source2.pub, each user will be able to verify packages intended for the other. I'd rather each user not know about the other's public keyring. Is there a way I can specify an alternate or supplementary pubkey database on a per-user or per-rpm(8)-invocation basis?

• How to invoke a command using specific proxy server?

  - by Xiè Jìléi

  Some applications support proxy (http proxy or socks proxy), and some are not. For browsers, I can specify proxy server in the preferences/options dialog, and other applications may be able to configure proxy servers in config files. For general purpose, can I invoke a command using a specific proxy? Like following: $ proxy-exec --type sock5 --server 1.2.3.4:8000 -- wget/ftp ... I'm using Ubuntu Maverick. P.S. In win32, it can be implemented by hijacking the socket dlls, maybe, I'm not familiar with Linux programming, but I guess it's possible in Linux. though.

• Create intentional border with xrandr

  - by benizi

  Is there a way to tell xrandr "this space intentionally left blank"? I have a laptop that drives its internal display at 1920x1080, but the external monitor I'm using, due to its different aspect ratio, doesn't have that mode. It runs at 1920x1200. So, the basic setup: xrandr \ --output LVDS-1 --mode 1920x1080 \ --output DP-1 --mode 1920x1200 --same-as LVDS-1 [not to scale:] +-----------------------------------+ ¦ ¦ ¦ ¦ (laptop) ¦ (external) ¦ ¦ (LVDS-1) ¦ (DP-1) ¦ ¦ ¦ ¦ ¦ ¦ ¦ +-----------------¦ ¦ (blank...) ¦ ¦ +-----------------+ How can I specify that the 1920x120-sized region below LVDS-1 should be displayed as a black bar that can't be accessed by mouse on DP-1? I tried just coping with --panning 1920x1200+0+0/1920x1080+0+0/0/0/0/120, but I found the screen movement to be very annoying. Update: I found a workaround. (Update 2: changed it to an answer, per suggestion -- workaround doesn't answer the underlying question of leaving space blank.)

• How to make nginx only respond to one domain?

  - by larryzhao

  I am pretty new to nginx, I host my rails application on nginx+passenger. I want my website to be accessible to only one domain. So I set my nginx conf like the following: server { listen 80; server_name mydomain.com www.mydomain.com; root /var/deploy/myapp/current/public; passenger_enabled on; location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ { expires 1y; add_header Cache-Control public; } } I specify the server_name directive, but still, it answers anything which points to this IP and I could see that in the access.log that it answers to other domain names. Is there anything I am doing wrong?

• How do I change the NGINX user?

  - by danielfaraday

  I have a PHP script that creates a directory and outputs an image to the directory. This was working just fine under Apache but we recently decided to switch to NGINX to make more use of our limited RAM. I'm using the PHP mkdir() command to create the directory: mkdir(dirname($path['image']['server']), 0755, true); After the switch to NGINX, I'm getting the following warning: Warning: mkdir(): Permission denied in ... I've already checked all the permissions of the parent directories, so I've determined that I probably need to change the NGINX or PHP-FPM 'user' but I'm not sure how to do that (I never had to specify user permissions for APACHE). I can't seem to find much information on this. Any help would be great! (Note: Besides this little hang-up, the switch to NGINX has been pretty seamless; I'm using it for the first time and it literally only took about 10 minutes to get up and running with NGINX. Now I'm just ironing out the kinks.)

• Which FTP Daemon should I use if I want to use MySQL for authentication?

  - by wag2639

  We want to set up a FTP Daemon on our Ubuntu 10.04 server that can use a simple (probably custom) built web interface for a FTP server using MySQL for authentication. It'll be public facing but only intended for use by a few customers or clients. I know vsftpd, ProFTPd, and Pure-FTPd but I'm not sure which is best for this application. Main features we would like: a. Very good MySQL authentication integration b. Able to specify a list folders/files (folder level is sufficient) each user has access to through MySQL Anything else would just be sprinkles on top.

• OpenVPN (HideMyAss) client on Ubuntu: Route only HTTP traffic

  - by Andersmith

  I want to use HideMyAss VPN (hidemyass.com) on Ubuntu Linux to route only HTTP (ports 80 & 443) traffic to the HideMyAss VPN server, and leave all the other traffic (MySQL, SSH, etc.) alone. I'm running Ubuntu on AWS EC2 instances. The problem is that when I try and run the default HMA script, I suddenly can't SSH into the Ubuntu instance anymore and have to reboot it from the AWS console. I suspect the Ubuntu instance will also have trouble connecting to the RDS MySQL database, but haven't confirmed it. HMA uses OpenVPN like this: sudo openvpn client.cfg The client configuration file (client.cfg) looks like this: ############################################## # Sample client-side OpenVPN 2.0 config file # # for connecting to multi-client server. # # # # This configuration can be used by multiple # # clients, however each client should have # # its own cert and key files. # # # # On Windows, you might want to rename this # # file so it has a .ovpn extension # ############################################## # Specify that we are a client and that we # will be pulling certain config file directives # from the server. client auth-user-pass #management-query-passwords #management-hold # Disable management port for debugging port issues #management 127.0.0.1 13010 ping 5 ping-exit 30 # Use the same setting as you are using on # the server. # On most systems, the VPN will not function # unless you partially or fully disable # the firewall for the TUN/TAP interface. #;dev tap dev tun # Windows needs the TAP-Win32 adapter name # from the Network Connections panel # if you have more than one.
