• how to know which display number for the variable DISPLAY to be exported when ssh to server

  - by insidepower

  When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only export DISPLAY=localhost:0 && xclock export DISPLAY=localhost:1 && xclock export DISPLAY=localhost:2 && xclock export DISPLAY=localhost:... until the clock appear. Then i will use that display number. Each time log in to the server, the display number which is able to tunnel the gui data correct would be different. I know many of such similar questions has been asked and answer. However I couldn't find answer to my question, anyone know about it? Thanks!

• Is LDAP typically used in conjunction with SAP?

  - by michael

  I have potential clients that all use SAP. To avoid silent push back from IT, we want to make sure we don't add extra complexity to their job if the client (our client internal to the company is not IT) wants to adopt our SaaS. One way to avoid headaches is to add support for LDAP in our SaaS (a bit of work, but nothing major) ahead of time and make sure to mention that to IT. I really know nothing about SAP. Does SAP use an internal or external LDAP server usually? Updated question: A Company relies on an Asset management product from SAP. If I wanted to provide a SaaS that shares space in their workflow, is it advisable to use the SAP product authentication service (if it exists), and if so, do they provide an API?

• Any way to disable specific CPU idle (Cx) states?

  - by Philippe

  I just got a new Toshiba Tecra S11 notebook, which has a Core i5 520M CPU, and it appears to suffer from a well-known problem: a high pitched noise when the CPU is idle. Googling around revealed that this is caused by a specific power-saving mode in the CPU. In most cases, C4 mode is blamed for the noise. So my question is: is it possible to disable C4 mode (or any other "sleep" mode) using some utility or BIOS setting? I don't mind if it hurts battery life. I'd appreciate any advice on this matter. It's driving me crazy. FYI: I'm running Windows 7 64-bit

• How to set my Ubuntu account to super user at all times?

  - by iaddesign

  I have the latest Ubuntu installed and I'll be the only one using it off the network. My question is: how can I make myself super user at all times? Because when I try to delete a file it says I don't have privileges to do so. I know you are going to say it's a security risk but I'm off the network and want to learn all that I can. I don't want to delete the files through the terminal but want to do it through the user interface/explorer. I've installed LAMP and can't copy my site to the www directory. I've tried to remove the preinstalled index file and it won't let me.

• mac os x default editor for .dotsystemfiles

  - by jasonkuhrt

  This is a seemingly simple question but I can't find an answer so far despite search quite a bit. I'd like that when I open a .dotsystemfile in finder (i.e. .htaccess or .vimrc) it opens in a different editor than textedit. Doing the regular change-all in the info panel won't do the trick as it gives the following error: " An error occurred while changing the application that opens “.vimrc” because not enough information is available. Do you want to open “.vimrc” with “MacVim.app”? " This isn't a huge issue but it is like a small splinter that I've love removed. Thanks for any helpful information.

• CPU Configuration Issue for 2 Servers (Server 2008 R2)

  - by Bill Moreland

  I have 2 servers running the exact same Classic ASP code with Access DBs (yes, not ideal, but it is what it is, for now). 1) Xeon 5520 @ 2.27 GHz (6 GB Memory) 2) Xeon E5-2620 @ 2.00 GHz (2 processors, 32 GB Memory) For most pages the newer E5-2620 processes the pages between 10-15% faster. On pages requiring heavy and/or multiple complicated access stored procedures (queries) the older 5520 does a much better job. I believe the servers are configured nearly identically. My question: is it possible that the newer, multi-processor server is not as good at handling Classic ASP as the older single processor? Is there a configuration difference that needs to be in place that I'm missing since I'm shooting for identical implementations?

• How to set up server to be accessed from mobile devices [closed]

  - by Kgrover

  I need to set up a server that will eventually be accessed from an Android application. I don't have experience with how to go about this, but I've seen MySQL servers (Amazon EC2). I would need to store data on the server remotely (again, from a mobile device) and fetch it to display. What would be the best kind of server to use? I'm guessing I would only need around 50 GB of space. Is it possible to use a network drive and set that up as a remote server with an IP address? I would need to upload and extract data through java on Android. This is my first question on ServerFault, and I'm not sure if it's the appropriate forum. If not, please redirect me.

Please help me out. =) (Obviously, free software shareware.)

• Am I supposed to assign the broadcast IP somewhere?

  - by pvieira

  This is a very basic question from a newbie point of view. I have a dedicated server at Hetzner running Windows 2008 R2. I bought a subnet of IP addresses to use in this server. They provided me a given range of IPs, incluind one Ip labeled as "Broadcast". I know how to assign those IPs to the NIC, but should I do something with the Broacast IP, like configure it somewhere on Windows? Or can I just ignore it and I'll be fine? This IP range will be used to host SSL sites.

• Is it possible with Google searches to ban any and all results from a domain? [closed]

  - by Stu Thompson

  Is it possible to configure Google somehow to permanently ban search results from domains that I know 100% are never, ever going to make me happy? Something cookie/session based maybe? E.g. I want to ban (permanently, forever and always) results from experts-exchange.com. Every time I click results that take me to their page I just want to scream. Update! Google has released a Chrome Extension to allow users to block individual site from Google search results! Personal Blocklist (by Google). (Since this question has been closed, I cannot answer it.)

• Is putting swapfile & temp folder in ramdisk a good idea in Windows 7 64 bit with lots of ram?

  - by Tony_Henrich

  I want my Windows to run as fast as possible. If I have 12GB ram in Windows 7 64bit, quad core cpu, and all apps fit in memory, will the swap file ever be used for anything? The question is about if its a good idea to put the swap file in a ram disk. Would a ram disk help in any way or will Windows intelligently use all the available memory for all its work? I am also thinking of putting the temp folder in a ram disk. I know ram disk is volatile memory and I don't care about its content in it if it gets lost.

  - by Somebody still uses you MS-DOS

  My question mark key in my keyboard isn't working. ("?"). I've tried to use xev and showkey -k to try to identify at least it's code and manually use xmodmap to mao this key. Unfortunately, the keys aren't being detected in neither utilities. I'm using Ubuntu 10.04 in a Virtual Machine, and my Kernel is 2.6.32-22-generic. What can this be? It's not a special multimedia key, it's a simple one. I would like to understand what exactly is happening so at least I can try to better debug this issue.

I found on the Lightning forum that this bug was fixed in Lightning V.1.0b2 So my question is : why do I still have this bug ??? Best regards

• Can I use applescript to click buttons in background?

  - by Giorgio

  Sorry for this generic and probably bad-written question. I've never programmed in applescript, but I'm quite familiar with other coding language. I'm in the need of clicking on 2 sequential button inside the lobby of a software (when you click the first a popup appears and we should click 'ok'). However things are a little bit more complicated then this because: 1) the lobby of this program isn't in foreground: it's covered by other windows opened. (I don't have experience so I don't know if this represent a problem). 2) there should be a timer and the program should click this button at regular intervals. Is this feasible with applescript?

• Windows 7 Laptop, cursor jumping after typing the letters "y" or "t" [closed]

  - by Dave K

  My wife has an HP laptop running windows 7. She has a very frustrating problem when typing: in some, but not all cases, typing the letter's "y" or "t" will cause the cursor to jump back a few lines or some number of words. The result is that she ends up typing over whatever it was that she was working on. (as a matter of fact, I just experienced this while typing this question on her computer with the phrase: "typing the letter..." above.) I've installed the latest drivers for her touchpad from Synaptic and disabled tap touching and gesture features to rule out simple unintended mouse clicks. Still the "y" and "t" keys continue to cause problems.

• IIS 6 is no longer installed after computer restart.

  - by jarrettcoggin

  I was doing some maintenance on a build server at work and I changed some various settings (registry settings for custom applications, user permissions, etc.), then I restarted the machine. When the machine came back up, I couldn't access a website that is hosted on this machine, so I went digging around. It seems as if IIS6 was somehow uninstalled, which I know I didn't do. My question is: What would cause this? I've tried to reinstall it, uninstall it, reinstall it again, and nothing has changed. I still have a blank IIS Manager application (inetmgr), and no way to access these websites. BTW, the computer is running Windows Server 2003 R2 x64 Service Pack 2.

• Continue process after closing terminal?

  - by Jakobud

  Recently, I tried to unzip a 30 gig zip file on a remote system using Putty. As the long unzipping process continued, I closed Putty, assuming that the process would just continue to run on the remote machine. When I came back later and logged back into the machine again, I realized that the process must have stopped only part way through when I closed Putty. I wasn't expecting that to happen. My question is, how do I prevent this problem? Can I somehow fire off a process in the background? Or should just setup a one time cronjob that will run the process for me?

• Chrome : type in textboxes instead of selecting them

  - by rlb.usa

  Hi guys, not sure what is happening but quite often i go to highlight/doubleclick text in a textbox in Google's Chrome browser, and somehow the textbox itself gets selected. I have to redo my selection so it selects the text inside... It is hard to explain but is it possible that whenever I have a textbox selected, when I type, the text I type goes in the box (instead of nowhere)? It seems like a rather uh, silly/stupid question, but it would save me time and make my browsing more efficient. I can work a mouse and type just as well as anyone else, Chrome is the only browser I have trouble in where it likes to select the textboxes instead of the text inside the textboxes. I love Chrome.

• Soap client call has slow performance

  - by Alon_A

  OS is Centos 6.2 with PHP 5.3.15. We have a Facebook application that is using PHP soap web services. We sometimes experince slow preformance when connecting to these services, but we cant understand what exacly is causing the problem. We've try to analyse the behavior using the profiling tool Kcachgrind. Here is a call graph from the index.php page that took 21 seconds to load. You can clearly see that calling the soap client is the bottle neck. I've also noticed that exactly before the page finishes to load, this file is being created in our serve's /tmp folder: wsdl-apache-d1032d85dfd16c0d91a6b70facc70e43 These are the permission of /tmp drwxrwxrwt 6 root root 40960 Aug 30 10:39 tmp I know its not the most specific question, but if any one had similar performance issues with soap client, We would love some ideas about what can cause this kind of performance problem, what can we do to investigate more accurately or how to overcome the problem ? Thanks.

• Does Citrix XenServer have storage Migration [closed]

  - by Entity_Razer

  I'm trying to find out. I can't seem to find a defenitive yes / no answers so I thought I'd ask the ServerFault community this simple question: Does XenServer (in any version) support Storage migration such as VMWare's Storage VMotion capability, or Hyper-V's storage migration ? I'm trying to do a comparative study of all platforms but I can't find a website (preff. Citrix supported or any other "legit" source) where it say's a defenitive yes or no. Anyone able to answer this one for me ? Cheers !

• 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?

• Specific apache + mysql settings for a light-weight site

  - by Good Person

  I have a small website with a Joomla and a Moodle set up. It seems that both of these are very slow. The server (CentOS release 5.5 (Final)) is a virtual dedicated server with about 2GB of ram. I don't expect to ever get more than 10-15 people on at the same time (and if that is high) What settings could I change in either apache, mysql, or even the OS to increase the performance of my site? I'm not concerned about running out of resources if I get too many visitors. If you need more specific data leave a comment and I'll edit the question.

• Application got shut down in WinXP if I close the 2nd window of that application.

  - by kinopyo

  I'm using WinXP and here is my question: I run an application, such as Chrome, there would be one app in the task bar, and it's fine. Suppose a new window of Chrome opened(so there would be 2 window and 2 in the task bar), and when I close that,the 2nd one, the whole application just shutdown. And so does chrome, firefox, evernote, Becky!(the email client), even TortoiseSVN. So I think there should be a generic problem cause these applications shutdown, such as the platform - WinXP. Please give me some advice or hint, anything comes to your mind would be helpful!
