  • Manually closing a port from commandline

    - by codingfreak
    Hi I want to close an open port which is in listening mode between my client and server application. Is there any manual command line option in Linux to close a port ?? NOTE: I came to know that "only the application which owns the connected socket should close it, which will happen when the application terminates." I dont understand why it is only possible by the application which opens it ... But still eager to know if there is any another way to do it ??

  • windows 2008 server login screen remote desktop

    - by Marki
    how can I access a GRAPHICAL login screen (like on earlier Windows versions, or like VNC) instead of the Username/Password prompt via RDP? I'm asking because we have several servers where we have no passwords but the shutdown/reboot option is given via group policy on the login screen. Thus, instead of having to go the hardware console I'd like to be able to perform reboot/shutdown actions via terminal services. Regards, Marki

  • What the best way to achieve RPO of zero and lowest possible RTO (less than 15 minutes) with SQL 2008 R2?

    - by Adrian Hope-Bailie
    We are running a payments (EFT transaction processing) application which is processing high volumes of transactions 24/7 and are currently investigating a better way of doing DB replication to our disaster recovery site. Our current and previous strategies have included using both DoubleTake and Redgate to replicate data to a warm stand-by. DoubleTake is the supported solution from the payments software vendor however their (DoubleTake's) support in South Africa is very poor. We had a few issues and simply couldn't ever resolve them so we had to give up on DoubleTake. We have been using Redgate to manually read the data from the primary site (via queries) and write to the DR site but this is: A bad solution Getting the software vendor hot and bothered whenever we have support issues as it has a tendency to interfere with the payment application which is very DB intensive. We recently upgraded the whole system to run on SQL 2008 R2 Enterprise which means we should probably be looking at using some of the built-in replication features. The server has 2 fairly large databases with a mixture of tables containing highly volatile transactional data and pretty static configuration data. Replication would be done over a WAN link to a separate physical site and needs to achieve the following objectives. RPO: Zero loss - This is transactional data with financial impact so we can't lose anything. RTO: Tending to zero - The business depends on our ability to process transactions every minute we are down we are losing money I have looked at a few of the other questions/answers but none meet our case exactly: SQL Server 2008 failover strategy - Log shipping or replication? How to achieve the following RTO & RPO with logshipping only using SQL Server? What is the best of two approaches to achieve DB Replication? My current thinking is that we should use mirroring but I am concerned that for RPO:0 we will need to do delayed commits and this could impact the performance of the primary DB which is not an option. Our current DR process is to: Stop incoming traffic to the primary site and allow all in-flight transaction to complete. Allow the replication to DR to complete. Change network routing to route to DR site. Start all applications and services on the secondary site (Ideally we can change this to a warmer stand-by whereby the applications are already running but not processing any transactions). In other words the DR database needs to, as quickly as possible, catch up with primary and be ready for processing as the new primary. We would then need to be able to reverse this when we are ready to switch back. Is there a better option than mirroring (should we be doing log-shipping too) and can anyone suggest other considerations that we should keep in mind?

  • On a linux server how do you use multiple terminals over a single ssh connection?

    - by epochwolf
    I often find myself opening several ssh connections in order to view several log files at a time with tail -f. This isn't a problem when I'm at home because I use public key encryption for password-less login. However, I will often use computer at my university to do this so I don't have the option of using my private key. It gets annoying to enter my password 4 or 5 times to get several terminal windows. How can I get multiple terminals over a single connection?

  • How do I stop VMware player from resizing?

    - by Sean
    Hi! I just downloaded VMware player (I used to use Virtual Box, but I needed Windows Aero, and vbox doesn't support that yet) But it will automatically resize the guest when I resize the window, and I do not want that. I did not see an option to turn it off. Does anyone know? Thank you.

  • How to change the Internet Explorer 10 default search engine to Google?

    - by Ivo Flipse
    When I'm browsing I always use the address bar to search, but when I do this in Internet Explorer 10, I get taken to the default search engine Bing. So I started looking in the Internet Options to see if I could change it, but I couldn't find the right option. There's no clear way to add Google from this screen and when I clicked: Find more search providers..., you get taken to IE Gallery where Google isn't even listed. So how do I change my Internet Explorer 10 search engine to Google?

  • Connecting Evolution to MS Exchange via MAPI

    - by HorusKol
    I've been trying to get some information about the MAPI plugin for Evolution - but it all seems to in pieces everywhere, and also mostly a couple of years old. Anyone had any experience with getting Evolution connecting to MS Exchange via MAPI? Unfortunately, any other connection method (IMAP or WebDAV) is not an option - either because of not being allowed or just unusable.

  • rdate for Windows 2008

    - by Lars D
    I need a command line tool that adjusts the time of a Windows 2008 server, using an internet clock. The purpose is to adjust the time in a script, when other apps from that script are not running. It is not an option to use the built-in NTP service because that makes some apps on this server fail - note, that this server is used in an industrial environment with no PCs on the network and no Windows update or similar applied. Any idea, anyone?

  • Out of memory error while uploading file into a blob

    - by stacker
    I received a out of memory error SQL Error: 0, SQLState: 53200 from postgres while trying to upload a 10MB file into a single row with a column of blob-type bytea. Which configuration parameters should be changed to allow inserts of this size, or should this work out of the box without modifications? Is there an option like in informix-db to create so called blob-spaces?

  • How do I prevent ConEmu auto-attaching to every single cmd.exe?

    - by naxa
    I don't want ConEmu to attach to every cmd I open, but this is how it works now. I remember that I told ConEmu to do this, but I don't want it anymore. Maybe I just overlooked something, but I've read all the settings pages and I couldn't find an option to disable it. Am I missing something? How do I prevent ConEmu from attaching every single cmd.exe I open? My ConEmu version is 121109 x86, on winXPproSp3x86.

  • How can I use the "Windows Live Call Button" on my headphone to answer a call with Skype?

    - by Gnoupi
    Webcams and headphones from Microsoft (like for example the LifeChat ZX-6000, in my case) have a button which can be used only with Windows Live Messenger, to answer a call. There is no option provided to configure it so that it would launch a program, or work in another communicator, in the given drivers. Is there a way to make it work with Skype, so that I can answer a call by pressing this button? Maybe there are other drivers?

  • R2 live migration between Opteron 8354 and 2435

    - by Safin09
    As per title, will the processor compatibility option allow a live migrate between an AMD Opeteron 2435 (dual proc, hex core) and an AMD Opteron 8354 (quad proc, quad core)? We are out of capacity and wish to use a newer dual socket server rather than an older (yet much more expensive) quad socket server in our cluster.

  • Is there a unix command to output time elapsed during a command?

    - by Olivier Lacan
    I love using time to find out how long a command took to execute but when dealing with commands that execute sub-commands internally (and provide output that allows you to tell when each of those sub-commands start running) it would be really great to be able to tell after what number of seconds (or milliseconds) a specific sub-command started running. When I say sub-command, really the only way to distinguish these from the outside is anything printed to standard out. Really this seems like it should be an option to time.

  • How to jump to a particular flag in a Unix manpage?

    - by dotancohen
    When reading a Unix manpage in the terminal, how can I jump easily to the description of a particular flag? For instance, I need to know the meaning of the -o flag for mount. I run man mount and want to jump to the place where -o is described. Currently, I search /-o however that option is mentioned in several places before the section that actually describes it, so I must jump around quite a bit. Thanks.

  • Illustrator export layers to png and keep layer names

    - by Jonny
    I have a set of 300 or so .ai files in which I will need to open each, separate one main layer into two (probably have to create an extra layer manually, and move needed stuff into that layer manually). Then I want to export those two layers to PNG. I would like to keep the layers' name in the output filenames. Any suggestion here? The save for web/devices doesn't seem to have an option for saving files using layer names.
