• How can I set deadline as the I/O scheduler for USB Flash devices by using udev rules?

  - by ????

  I have set CFQ as the default I/O scheduler. I often get bad performance when I write data into a Flash device. This is resolved if I use deadline as the I/O scheduler for USB Flash devices. I can't always change the scheduler manually, right? I think writing udev rules is a good idea. Can someone please write rules for me? I want: When I plug in a USB device, detect the type of the device. If it is a portable USB hard disk, do nothing (I think if a device has more than one partitions, it always a portable hard disk. If it is a USB Flash device, set deadline as it's scheduler.

• ASP.NET, URL Rewriting and threads on Linux?

  - by acidzombie24

  Right now converting my normal sql(ite) syntax into compatible MS Server syntax is driving me mad. My code seems to be mono compatible judging by MoMA. However in global.asax i start several threads in Application_Start to use as a service and excessive url rewrites in Application_BeginRequest (everything is rewriting into default.aspx which calls C# code/class baded on the url). The urls do not have extensions or my have false extentions ie mysite.com/username/page/title.lol - id I need it all to go to BeginRequest. I also need files to be downloadable. Usually the path will be rewritten as from /file/user/filename to /file/u/s/user/file. Would this be supported on linux+mono+a good webserver?

• USB mouse pointer only moving horizontally on macbook 6.2 with 12.04

  - by Glyn Normington

  After installing Ubuntu 12.04 on a macbook pro 6.2, the touchpad and external USB mouse worked perfectly. After rebooting I can't get either touchpad or external USB mouse to work. Sometimes no mouse pointer is visible, but more often I can only move the mouse pointer horizontally five sixths of the way across the display (from the top left). I have uninstalled mouseemu. xinput list shows the USB mouse. xinput query-state for the USB mouse shows the following: ButtonClass button[1]=up ... button[16]=up ValuatorClass Mode=Relative Proximity=In valuator[0]=480 valuator[1]=2400 valuator[2]=0 valuator[3]=3 and re-issuing this command with the pointer at its right hand extreme displays the same except for: valuator[0]=1679 So the valuator[0] seems to be the x-coordinate of the pointer and the range of motion 480-1679 is indeed about five sixths of the display width (1440). valuator[1] is suspiciously large given the display height is 900. Perhaps this is a side-effect of having previously been using a dual monitor (although booting with that monitor connected does not help). There are other entries listed under xinput list: Virtual core XTEST pointer which seems stuck at position (840,1050). bcm5974 which seems stuck at position (837,6700). Removing the bcm5974 module using rmmod disables the toucpad as expected but does not fix the USB mouse problem. After adding the module back, it is stuck at position (840,1050) instead of (837,6700). /etc/X11/xorg.conf was generated by nvidia-settings and contains: Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "ZAxisMapping" "4 5" although I don't know how plausible these settings are. Any suggestions?

• How do I stop track changes from turning on automatically in Word 2007

  - by Benj

  Whenever I open an existing document in Word 2007 (on Windows XP), word turns on track changes, and changes the display mode to "Final" (that is, not "Final Showing Markup" -- so I often don't even notice track changes is on if I don't remember to pay attention. This happens for ALL existing documents, and doesn't happen for new documents. I can't find any option in the configuration that would control this behavior. I would like to restore the original/default behavior where documents are opening with Track Changes off, and in "Final showing markup" display. Steps to Reproduce Open Word 2007. Create a new document. Verify that track changes is off. Save the document and close Word. Open the document (either directly or through Word). Track changes is now on. Any ideas?

• Migrating websites from IIS 6 to Apache Tomcat

  - by Cheeky

  I have 4 CFML coded websites currently running on Railo 3 (CFML engine using Resin) and IIS. I would like to upgrade my server and websites to Railo 4, which no longer uses Resin, but runs on Apache Tomcat. I have quite limited knowledge when it comes to web servers and I wanted to know what the process would be to move the websites from Railo 3 to Railo 4 without disrupting the live sites? Would there still be a need for IIS after the installation of Apache Tomcat? Does Tomcat run through IIS or are they two completely different things and would it be a complete move from IIS to Tomcat? If so, where would one then manage all those things one normally does in IIS, like default documents and host headers etc? Any advice would be extremely appreciated.

• How to draw diagrams in Open Office?

  - by Amokrane

  Hi, I would like to draw diagrams using Open Office but I didn't find any installed by default. What I am exactly looking for are diagrams that look like the ones that come with MS Office 2007/2010 (like Pyramid diagrams, Star diagrams etc.). Any idea? A plugin to install? Otherwise are there any online services that can do it? (I have tested Cacoo and gliffy but they don't really offer the diagrams that I am looking for). Thanks!

• Windows XP: Consequences of setting a password for an account

  - by sleske

  I do not quite understand how Windows (specifically Windows XP) handles accounts with/without passwords. As far as I can see, on a fresh Windows XP install I have one default account which has admin rights does not have a password will auto-login (without password prompt) when the computer boots What happens if I set a password for this account? Will it still auto-login? Or will it always prompt for the PW? And generally, what consequences does it have if I set a password? I noted that Scheduled Tasks apparently cannot run under an account w/o password (creating a scheduled task will prompt for the account PW). Is there anything that will not work with a password set? Why is it even possible to have accounts without a password? I have some Unix/Linux background, but the concepts appear a little different under Windows.

• Removing (Presumably) Extraneous Network Adapters from Device Manager (eg WAN Miniport)

  - by Synetech inc.

  Can anyone shed some light on the default items in the Network Adapters branch of the Windows Device Manager? In addition to the network card, there are always a bunch of other things that I cannot find any useful information on such as RAS Asynch Adapter and all the WAN Miniports (IKEv2, IP(v6), L2TP, Network Monitor, PPPOE, PPTP, SSTP). I would like to trim it down and uninstall whatever possible but cannot find out exactly what these items are responsible for (and therefore whether or not they are needed on my system). Most of the pages found with Google are either people trying to fix an error with such an item or someone asking what it is and being given an unhelpful, pat response like “just leave them alone” or “they’re necessary”. I highly doubt that is the case and I’m certain that at least some items can be removed because even if they become necessary in the future they can be added again (for example installing Network Monitor or Protowall reinstalls the miniport drivers anyway).

• How to make Ubuntu useradd behave like Centos useradd?

  - by Buttle Butkus

  I don't remember modifying CentOS useradd to get this behavior. useradd in CentOS creates the user's home directory with all the normal files (like .bashrc). I modified /etc/default/useradd to make it looks like CentOS (just required some uncommenting) except for Ubuntu having SHELL=/bin/sh instead of SHELL=/bin/bash How do I make useradd act like it does in CentOS? Is there some existing option to change? Or should I just add an alias to /etc/bash.bashrc? The difference: On Ubuntu, useradd is not creating the home directory. as root: $ useradd test $ cd ~test -su: cd: /home/test: No such file or directory

• External Full HD monitor and Virtual Desktop Size

  - by Stefan

  I have two FullHD monitors attached to my ATI graphics card [2]. The resolution of both of them is detected properly without any modifications to /etc/X11/xorg.conf. I can run both of them in clone mode. However, when I try to run them next to each other, I got the following error: The selected configuration for displays could not be applied. If tried to fix this according to [1]. My xorg.conf now looks like this: Section "Module" Load "glx" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 SubSection "Display" # The 1088 is the smallest multiple of 32 >= 1088 # see manpages Virtual 1920 1088 EndSubSection EndSection This does not seem to be parsed properly. After restarting X, I cannot set resolutions beyond 1600 or so any more. /var/log/Xorg.0.log gives: [ 15.676] (II) fglrx(0): Not using mode "1920x1080" (width too large for virtual size) [ 15.676] (II) fglrx(0): Not using mode "1680x1050" (width too large for virtual size) Are my modifications syntactically incorrect?

• Superscope DHCP leases and configuration set up

  - by Vdub

  Hello I wanted to see if someone could help with a network problem I am having. Right now we have a super-scope and scopes of 192.168.50.1 and 192.168.51.1, as of now both are activated but only 192.168.50.1 is handing our leases, 192.168.51 wont. here is a summary of our network Gateway: watchguard firebox x750e for our router/gateway at 192.168.50.1 I set up as a secondary IP address 192.168.51.1 Server: Server 2008 r2 standard, running our DNS @ 192.168.50.242 and 8.8.8.8 as a secondary, AD, and DHCP. On that NIC card i have 192.168.50.242 as the IP address and 192.168.51.242 as a secondary. 192.168.50.1 as the default gateway and 192.168.51.1 as a secondary. Im am not very knowledgeable at this but as far as i have researched after adding a super scope and activating scopes, they should automatically start handing out addresses and I cant figure out why only one does. any help at all would be appreciated.

• How to Install WebLogic 12c ZIP on Linux

  - by Bruno.Borges

  I knew that WebLogic had this small ZIP distribution, of only 184M, but what I didn't know was that it is so easy to install it on Linux machines, specially for development purposes, that I thought I had to blog about it. You may want to check this blog, where I found the missing part on this how to, but I'm blogging this again because I wanted to put it in a simpler way, straight to the point. And if you are looking for a how to for Mac, check Arun Gupta's post.  So, here's the step-by-step: 1 - Download the ZIP distribution (don't worry if your system is x86_64)Don't forget to accept the OTN Free Developer License Agreement! 2 - Choose where to install your WebLogic server and your domain, and set as your MW_HOME environment variableI will use /opt/middleware/weblogic for this how to export MW_HOME=/opt/middleware/weblogicMake sure this path exists in your system. 'mydomains' will be used to keep your WebLogic domain. mkdir -p $MW_HOME/mydomain 3 - If you don't have your JAVA_HOME environment variable still configured, do it. Point it to where your JDK is installed. export JAVA_HOME=/usr/lib/jvm/default-java 4 - Unzip the downloaded file into MW_HOME unzip wls1211_dev.zip -d $MW_HOME 5 - Go to that directory and run configure.sh cd $MW_HOME ./configure.sh 6 - Call the setEnvs.sh script . $MW_HOME/wlserver/server/bin/setWLSEnv.sh7 - Create your development domain. It will ask you for username and password. I like to use weblogic / welcome1cd $MW_HOME/mydomain $JAVA_HOME/bin/java $JAVA_OPTIONS -Xmx1024m \ -Dweblogic.management.allowPasswordEcho=true weblogic.Server8 - Start WebLogic and access its web console(sh startWebLogic.sh &); sleep 10; firefox http://localhost:7001/consoleUsually, it takes only 10 seconds to start a domain, and 5 more to deploy the Administration Console (on my laptop). :-)Enjoy!

• How to limit access to Exchange 2003 Mobile Activesync server by user?

  - by micilin

  So I was asked to set up an Exchange Activesync mobile gateway. That's done. It's a separat eExchange 2003 front-end server configured for SSL, and I've put an off-domain ISA server in front of it. Now I'm being asked to limit which users can connect to it. By default an Exchange front-end server allows any user who has a mail account to connect to the front -end server. So I'm looking at the permissions on the various IIS sites/apps on the server, but I know that it's easy to break Exchange Front-end server perms. So I've got the following in IIS: Exadmin Exchange EchWeb Microsoft-SErver-ActiveSync MobileAdmin OMA And a couple of others that I dont think are relevant. Can I change the permissions on one of these to restrict who can connect to Activesync? As a bonus: Can I do it in a way that does not affect ordinary browser based Exchange Access? Thanks in Advance!!

• What router settings to use for wireless home network

  - by Question Overflow

  While looking at the setting of my wireless router, I am bewildered by the array of options available. Despite searching on Wikipedia to try to understand the various acronyms, I am still clueless to decide what is the best setting to use although the default works fine. Rather than calling the internet service provider (ISP) to ask them the correct settings, I hope to learn more about the differences between some of the options listed below, so that I would be able to make a more informed decision from now onwards: PPPoE vs PPPoA LLC vs VC-Mux Bridge vs Routed In addition, I would also like to know the significance of the following MTU VPI VCI And whether or when I should manually specify DNS?

• login as rsh in rhel 6 without entering password

  - by cartmancakes

  I need to be able to login to a RHEL 6 server using rsh (please don't flame me about security, it's irrelevant in this particular instance) as root without having to enter a password. My procedure for setting this up works great in RHEL 5.x, but does not work in RHEL 6. I suspect this has something to do with PAM, but I'm inexperienced with how to use PAM. Can someone help me with this? /etc/pam.d/rsh auth required pam_rhosts.so auth required pam_nologin.so account include common-account password include common-password session required pam_loginuid.so session include common-session /etc/pam.d/rlogin auth required pam_nologin.so auth [user_unknown=ignore success=ok ignore=ignore auth_err=die default=bad] pam_securetty.so auth sufficient pam_rhosts.so auth include common-auth auth required pam_mail.so account include common-account password include common-password session required pam_loginuid.so session include common-session Thanks!

• Server 2003 RAS Server Utilising High WAN Traffic

  - by Joe Sergeant

  We have Routing and Remote Access configured on Server 2003 (also our primary domain controller), allowing users to connect in remotely to access files, email, etc. With one user, the RAS Server is constantly sending data to that user's remote computer. From 9am this morning it has transferred almost 800MB. The user isn't transferring any files remotely, certainly not enough to total 800MB anyway. None of the other remote users have had this issue. We have ensured that the user in question has "Use default gateway on remote network" disabled for both IPv4 and IPv6 and we are fairly confident that Offline Files isn't trying to synchronise with the server remotely, too. My question is two-fold. Firstly, has anyone had a similar experience? Secondly, what would be the best software to discover exactly what data is being sent to the remote user?

• FullText SQL Server Clustered Service Move

  I need to move the I drive from one san vendor to another. Microsoft states that you can't move the fulltext http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q304282& and the only way would be remove the cluster and re-install the cluster. Does anyuone know of any other way? Would swapping the old I drive for a new I drive work? Currently on the I drive I just have the fulltext directory and sql server log directory to move. The later I know how to handle. Any help would be greatly appreciated Windows 2003 - SQL Server 2005 32bit and yes this is one of the few 2005 instances that we have left Steve

• Can't install Linux drivers for ASUS N-13 wireless adapter

  - by jcc

  I have a USB N13 wireless Adapter with install CD-- For Windows. I downloaded drivers from ASUS FOR N13 for Linux. Disregard install CD that came with adapter; it's for Windows. I then downloaded Windows Wireless driver install program app from Software Center in Ubuntu 12.10. The problem is me. I am newbie with all things linux; software sources, G Debi, default archive manager, synaptic package manager and the Terminal. The downloaded driver file is a .zip file. I managed to extract it to a tar.gz file and then to open it to the contained files. When I use the Windows Wireless driver program it ends up telling me there is no .inf file and goes no further. It wants to install .inf file but I don't even see one in all the files. Can someone please help me . I think you can tell by my wording I don't have a clue. I hope this is'nt too chatty. I've tried to be explicit and to the point. Thank you. Oh, this is on an ASUS LAPTOP K53E. I've looked all over Ask Ubuntu and finally found some questions even on the N13 but they didn't help; still some differences in the exact problem.

• How to deny access to disabled AD accounts via kerberos in pam_krb5?

  - by Phil

  I have a working AD/Linux/LDAP/KRB5 directory and authentication setup, with one small problem. When an account is disabled, SSH publickey authentication still allows user login. It's clear that kerberos clients can identify a disabled account, as kinit and kpasswd return "Clients credentials have been revoked" with no further password / interaction. Can PAM be configured (with "UsePAM yes" in sshd_config) to disallow logins for disabled accounts, where authentication is done by publickey? This doesn't seem to work: account [default=bad success=ok user_unknown=ignore] pam_krb5.so Please don't introduce winbind in your answer - we don't use it.

• Weird bug in Visual Studio 11 Beta when running on Windows 8

  - by raccoon_tim

  With the Windows 8 Consumer Preview version out in the open and the Visual Studio 11 Beta also available, I’ve been putting some more effort into trying them both out. The first impression of the new Visual Studio 11 build was: Why doesn’t it work at all on Windows 8?! The issues I encountered were odd to say the least. Visual Studio did install correctly, which was a good sign, but when I started it, I was greeted with a multitude of popups each telling me that some package could not be loaded. So I clicked away for quite some time to finally be greeted by the new default visual style of Visual Studio. The next thing I wanted to do was start a new project so I pressed “New Project” and got the “Microsoft.VisualStudio.Dialogs.DialogInitializationException” exception. After some pondering and even submitting a bug report I found another already reported bug “http://connect.microsoft.com/VisualStudio/feedback/details/727578/vs-do-not-work-with-finnish-number-format-on-w8-64-bit”. It turns out that the dialog initialization failure has something to do with the packages no being loaded and following the presented workaround helped. The trick is to change the negative number sign to “-“ (U+002D) from the additional settings of your regional settings. This issue appears to have a wider reach than just Visual Studio as I heard at TechDays Finland 2012 that the same fix has to be made when using Hyper-V.

• Setting up the metasploitable in virtualbox

  - by SetSlapShot

  I'm supposed to try and use kali to do exploits on metasploitable, but I'll burn that bridge when I get there. My question right now is: How do I set up a host only network on virtualbox? I heard that it was unsafe to run metasploitable in bridged networking mode, that host only or NAT is better. When I run metasploitable on NAT, the kali box (attacker) has the same ip address as the metasploitable box, and nmap doesn't really return anything except what I can only assume would be a scan of its own ports? I tried to create a host only network in virtual box. I left the adapter settings at the default, and unchecked DHCP server. now when I run ifconfig on the metasploitable box, there is no ip address listed. Am I setting up/connecting to/not configuring the host only network correctly?

• After installing Ubuntu how do I get rid of unity and go back to gnome?

  - by aseq

  After I have installed the newest Ubuntu LTS release (12.04, still in beta though) I am greeted with an unfamiliar and difficult to use desktop environment. I believe it is called unity. However I have used gnome for a decade and a half and I would not like to move to this new and (for me) unusable desktop environment. What is a quick and easy way to remove (most) of unity and bring back gnome, as well as configure my display manager to load gnome by default with the environment as close as possible to the way it was before?

• How do I add more than one command to /etc/rc.local?

  - by Andreas

  I want to add two power saving commands to /etc/rc.local file. This to dissable bluetooth: rfkill block bluetooth And this to reduce screen brightness: echo 3024 > /sys/class/backlight/intel_backlight/brightness Separately added to /etc/rc.local they work but not both of them together like this: #/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. echo 3024 > /sys/class/backlight/intel_backlight/brightness rfkill block bluetooth exit 0 How do I add the two commands to get them properly executed at start-up? Update It turned out to be a timing issue. I fixed it by delaying the execution of the first command thus: (sleep 5; echo 3021 > /sys/class/backlight/intel_backlight/brightness)&
