• Docking Station Disabling/Enabling Network Connection

  - by bryan_cook

  Whenever I dock my laptop onto my docking station, Windows disables my Wireless Network Connection and enables my Wired Network Connection. Whenever I undock my laptop, Windows disables my Wired Network Connection and enables my Wireless Network Connection. Is there a way to disable this feature? After Windows performs the automatic disabling/enabling, I run into errors when I try to disable the now-enabled connection, specifically "It is not possible to disable the connection at this time. This connection may be using one or more protocols that do not support Plug-and-Play, or it may have been initiated by another user or the system account." I'm assuming the latter portion of the error is true ... my network connections are being enabled/disabled under a system account. Regardless, I'd just like to disable the feature altogether. For reference, I'm working with Windows XP Professional on a Dell Latitude D630. Thanks in advance!

• New LAMP server, all links redirecting to localhost

  - by serilain

  I've got a very frustrating issue with what should be a bespoke install of Ubuntu 12.04, the LAMP config provided in apt-get install lamp-server^, and a web application called The Fascinator. After installing those three things and making no changes to any of them, I can access the application through a public IP (http://lib-hf1.lib.sfu.ca:9997 for the curious), but the domain of every link within that page is changed to localhost, including links to images and CSS, so nothing loads correctly and all of the links are broken. I've Googled around and found some people who appear to be having this issue with WP and Drupal, but nothing makes reference to a system-wide setting, and no one using the Fascinator seems to be having this issue. I have a faint memory that this might have something to do with mod_rewrite, but I'm pretty well stumped.

• Unexpected behavior in Bash

  - by cYrus

  From man bash: A simple command is a sequence of optional variable assignments followed by blank-separated words and redirections, and terminated by a control operator. The first word specifies the command to be executed, and is passed as argument zero. The remaining words are passed as arguments to the invoked command. So it's perfectly legal to write: foo=bar echo $foo but it doesn't work as I expect (it prints just a newline). It's quite strange to me since: $ foo=bar printenv foo=bar TERM=rxvt-unicode [...] Could someone please explain me where I'm doing wrong?

• Varnish does not recognize req.hash

  I have Varnish 3.0.2 on Redhat and service varnish start fails after I added vcl_hash section. I did varnishd and then loaded the vcl using vcl.load vcl.load default default.vcl Message from VCC-compiler: Unknown variable 'req.hash' At: ('input' Line 24 Pos 9) set req.hash += req.url; --------########------------ Running VCC-compiler failed, exit 1 cat default.vcl backend default { .host = "127.0.0.1"; .port = "8080"; } sub vcl_recv { if( req.url ~ "\.(css|js|jpg|jpeg|png|swf|ico|gif|jsp)$" ) { unset req.http.cookie; } } sub vcl_hash { set req.hash += req.url; set req.hash += req.http.host; if( req.httpCookie == "JSESSIONID" ) { set req.http.X-Varnish-Hashed-On = regsub( req.http.Cookie, "^.*?JSESSIONID=([a-zA-z0-9]{32}\.[a-zA-Z0-9]+)([\s$\n])*.*?$", "\1" ); set req.hash += req.http.X-Varnish-Hashed-On; } return(hash); } What could be wrong?

• Bash script to keep last x number of files and delete the rest

  - by Brady

  I have this bash script which nicely backs up my database on a cron schedule: #!/bin/sh PT_MYSQLDUMPPATH=/usr/bin PT_HOMEPATH=/home/philosop PT_TOOLPATH=$PT_HOMEPATH/philosophy-tools PT_MYSQLBACKUPPATH=$PT_TOOLPATH/mysql-backups PT_MYSQLUSER=********* PT_MYSQLPASSWORD="********" PT_MYSQLDATABASE=********* PT_BACKUPDATETIME=`date +%s` PT_BACKUPFILENAME=mysqlbackup_$PT_BACKUPDATETIME.sql.gz PT_FILESTOKEEP=14 $PT_MYSQLDUMPPATH/mysqldump -u$PT_MYSQLUSER -p$PT_MYSQLPASSWORD --opt $PT_MYSQLDATABASE | gzip -c > $PT_MYSQLBACKUPPATH/$PT_BACKUPFILENAME Problem with this is that it will keep dumping the backups in the folder and not clean up old files. This is where the variable PT_FILESTOKEEP comes in. Whatever number this is set to thats the amount of backups I want to keep. All backups are time stamped so by ordering them by name DESC will give you the latest first. Can anyone please help me with the rest of the BASH script to add the clean up of files? My knowledge of BASH is lacking and I'm unable to piece together the code to do the rest.

• What is the list of special variables available when writing a shell command for a context menu

  - by giovanni.pellicciotta

  When extending the Windows' shell context menu (e.g. for adding an 'Open command here' prompt on directories), a 'command' key needs to be created in the registry. The value of this 'command' key apparently can be any valid command line. I want to know which 'special variables' are available for use inside this command line. For example, I use following command for opening and cmd window from within a directory's context menu (*): cmd.exe /e:on /f:on /s /k pushd "%V" I cannot find any reference to what %V actually means or what the full list of such variables is. (*) Following registry keys are created for this: [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\cmdshell] @=Open Command Prompt Here" HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\shell\cmdshell\command] @="cmd.exe /e:on /f:on /s /k pushd \"%V\""

• Best practice for making code portable for domains, subdomains or directores

  - by Duopixel

  I recently coded something where it wasn't known if the end code would reside in a subdomain (http://user.domain.com/) or in a subdomain (http://domain.com/user), and I was lost as to the best practice for these unknown scenarios. I could thinks of a couple: Use absolute paths (/css/styles.css) and modrewrite if it ends up being /user Have a settings file and declare a variable with the path (<? php echo $domain . "/css/styles" ?>) Use relative paths (../css/styles.css). What is the best way to handle this?

• Starting/Stopping IBM WebSphere Application Server (WAS) 7 from the Command Line

  - by Christopher Parker

  I've written a script to automate the process of starting, stopping, and restarting WAS7 from the command line. Nothing starts automatically on one of our staging servers, so I have to start everything: deployment manager, node agent, app server, and Web server. The script I wrote seems to work pretty well. A coworker of mine recommended that I structure my commands differently. I'm wondering if there's a good, valid reason for doing so. First, my variables: WAS_HOME="/opt/IBM/WebSphere/AppServer" WAS_PROFILE_NAME="AppSrv01" WAS_APP_SERVER="server1" WAS_WEB_SERVER="webserver1" How I had the start commands: "${WAS_HOME}/bin/startManager.sh" "${WAS_HOME}/bin/startNode.sh" -profileName $WAS_PROFILE_NAME "${WAS_HOME}/bin/startServer.sh" -profileName $WAS_PROFILE_NAME $WAS_APP_SERVER "${WAS_HOME}/bin/startServer.sh" -profileName $WAS_PROFILE_NAME $WAS_WEB_SERVER I was told that I should do it like this, instead: WAS_DMGR="Dmgr01" # Added variable "${WAS_HOME}/profiles/${WAS_PROFILE_NAME}/bin/startNode.sh" "${WAS_HOME}/profiles/${WAS_DMGR}/bin/startManager.sh" "${WAS_HOME}/profiles/${WAS_PROFILE_NAME}/bin/startServer.sh" $WAS_APP_SERVER "${WAS_HOME}/profiles/${WAS_PROFILE_NAME}/bin/startServer.sh" $WAS_WEB_SERVER How is the second way of starting up everything for WebSphere any better or more correct than the first, original, way?

• Re-using port 443 for another service - is it possible?

  - by Donald Matheson

  The ultimate goal is to allow a remote data connection service to operate on port 443 on a the SQL server. The application accessing the connection is behind a firewall and it is because of the client's reluctance to open another port that I have been asked to try and get this working. The current environment is Windows 2003 R2 (SP2) and SQL Server 2005. IIS is not installed, but when I try and install the third party connection software (SequeLink) it won't as it reports something is still configured on/using port 443. Netstat does not show anything listening on the port and I've tried editing the system32\drivers\etc\services file removing any reference to port 443 and also using sc delete to delete the HTTP and HTTPFilter (HTTP SSL in services console) services to see if this would help. Rebooting after each change. What could still be using the port? Is what I'm trying even possible (I have my doubts but have to investigate every avenue)? Any help/pointers would be greatly appreciated.

• Upgrade AirPort on Macs to support Snow Leopard's Wake on Wireless/WLAN?

  - by wojo

  Snow Leopard now supports Wake on WLAN, but not all hardware supports this. For example, my Octo Mac Pro from early 2008 has an AirPort card, but it does not support this. Nor does my 2007 2.33GHz MacBook Pro. For reference to what is needed, look at http://www.macrumors.com/2009/08/28/a-closer-look-at-snow-leopards-wake-on-demand-feature/ which includes a screenshot of what the System Profiler should show. It's pretty hard to find Apple parts, but is it possible to put newer cards into these machines to have them support Wake on Wireless?

• CloudFormation - How to start a Windows Service with cfn-init

  - by Edwin

  I'm creating a CloudFormation Stack that will install and start a service on a Windows Instance. I've figured out how to install the service, but how do I start the service using cfn-init? The examples seem to all use linux, as there is a reference to "sysvinit" How do I structure AWS::CloudFormation::Init so that cfn-init will start windows services after installing them? Do I leave in the sysvinit, replace it with something else, take it out? ps: I'm referring to how to start services by providing information to AWS::CloudFormation::Init.services. Also, It would be nice to know how "packages" work for windows. AWS's announcemnet says that packages are supported on Windows but there is no Windows specific documentation

• How to read the statistics in Media Player Classic?

  - by netvope

  I understand that the two numbers under bitrate are the average bitrate and the current bitrate of the stream. But what are the two numbers under buffers? I suppose the second one is the amount of data loaded in memory, but what is the first number? The amount of data decoded? Also, why are there a jitter and a sync offset? (For your reference, here stream 0-6 are video, audio track 1, audio track 2, subtitle track 1 and subtitle track 2.)

• Opening offline version of Microsoft Books Online in browser

  - by ercan

  I often use the MSDN website for language reference. In order to make navigation faster, I downloaded the offline version of SQL Server 2005 Books Online from here: http://www.microsoft.com/downloads/details.aspx?familyid=be6a2c5d-00df-4220-b133-29c1e0b6585f&displaylang=en The reason why it is 137MB is that it comes with its own GUI, which, not surprisingly, is rather poor! Apparently though, the pages are written in html. The URIs look like: ms-help://MS.SQLCC.v9/sqlcc9/html/674933a8-e423-4d44-a39b-2a997e2c2333.htm . I can open the URI in IE, but with errors. Do you know if I can open them with Firefox and how? Or is there a simple HTML version of "MS Books Online", for example in a ZIP file?

• Ubuntu: On-screen keyboard

  - by Paul Lammertsma

  On a similar note to this question, I recently booted Ubuntu to recover a Windows partition, but couldn't in any way get the keyboard to register. I recall back in 8.x that you could easily reach the on-screen keyboard (Virtual Keyboard?) via "Assistive Technologies". It seems to have disappeared since 9.x. For future reference, how can I easily get to it? Recall that in this scenario I won't have a keyboard to enter terminal commands (e.g. to install xkbd or something of the like).

• MySQL Workbench sends computer name with login not IP

  - by Android Addict

  I am attempting to connect MySQLWorkbench to a remote MySQL Server. The server has granted access to user@IPAddress However, when I try to connect MySQLWorkbench, it sends user@computername instead. How do I configure the connection to use the IP address instead in MySQLWorkbench? Reference: The remote server is on the local network, so I need to use the local IP address assigned to my client. EDIT What I have tried so far: from the server: mysql -u user@IPAddress -p --host=(ServerIPAddress) Returns: mysql> So that tells me the user account is operational. Furthermore, I confirmed it exists using: select user from mysql.user; returning a table of all users, of which the user I am using is present. I have also opened the port 3306: sbin/iptables -A INPUT -i eth0 -s clientIPAddress -p tcp --destination-port3306 -j ACCEPT Still I encounter Access Denied

• Verify server performance

  - by George Kesler

  I'm looking for a quick and SIMPLE way to verify that new servers are performing as expected. The most important metric is disk performance, second is network performance. I’m trying to prevent problems caused by misconfiguration of RAID arrays, NIC teaming etc. The solution should work with both physical and virtual servers. I don’t need sophisticated analysis with different workloads, just one set of benchmarks which I would run against a reference server and later compare to new ones. One problem is that most benchmarks are not giving accurate results when running on a VM.

• Advise about performance for local or remote SQL Server?

  - by TruMan1

  I currently have my web server and SQL Express / MySQL server on the same server. It is on a VPS. I have been having problems with my hosting so I am thinking of separating the web and db server into 2 VPS servers. Does anyone recommend this? I am worried that changing my setup from a local DB server to a remote one will degrade performance heavily. They will not be on the same network, but will reference each other via an IP address. Anything I should be aware of?

• What's using up my memory?

  - by Mehrdad

  I already know what's causing this -- it's the driver for FancyCache, which I'd installed myself. But as you can see, nothing in the screenshot tells me anything about this. I just happen to know. So the question is, if I didn't know this, how would I figure out what's using up so much of my RAM? (For reference: It's currently 1.7 GiB used, and the "missing" amount -- for FancyCache -- is 512 MiB. Clearly, that extra half-gigabyte not showing up anywhere I can see below.)

• Using AHK PostMessage to send WM_WININICHANGE to Program Manager

  - by SaintWacko

  I've written a script which updates an environment variable, but I need to tell Program Manager to update the computer's programs with this new information. I was given this as the API call that is made within another program to cause this: ::SendMessage(::FindWindow("Progman", NULL), WM_WININICHANGE, 0L, (LPARAM)"Environment"); I am attempting to translate this into an AutoHotKey PostMessage call, but I'm doing something wrong, as it isn't working. Here's where I've gotten so far: PostMessage, 0x1A,, (LPARAM)"Environment", "Program Manager" Here are the AHK resources I've been looking at to do this: List of Windows Messages Send Messages to a Window or Its Controls PostMessage / SendMessage And here are the resources that I used to figure out the original API call: SendMessage function WM_WININICHANGE message Can anyone help me figure out what I'm doing wrong?

• fsck: FILE SYSTEM WAS MODIFIED after each check with -c, why?

  - by Chris

  Hi I use a script to partition and format CF cards (connected with a USB card writer) in an automated way. After the main process I check the card again with fsck. To check bad blocks I also tried the '-c' switch, but I always get a return value != 0 and the message "FILE SYSTEM WAS MODIFIED" (see below). I get the same result when checking the very same drive several times... Does anyone know why a) the file system is modified at all and b) why this seems to happen every time I check and not only in case of an error (like bad blocks)? Here's the output: linux-box# fsck.ext3 -c /dev/sdx1 e2fsck 1.40.2 (12-Jul-2007) Checking for bad blocks (read-only test): done Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information Volume (/dev/sdx1): ***** FILE SYSTEM WAS MODIFIED ***** Volume (/dev/sdx1): 5132/245760 files (1.2% non-contiguous), 178910/1959896 blocks Thanks, Chris

• Gvim displays wrong font when set from _gvimrc, but correct font when set from menus

  - by dggoldst

  This question applies to gVim running on Windows. I have the following line in my _gvimrc set guifont=Lucida_Sans_Typewriter:h11:cANSI When gVim starts up, it strange italicizes everything! A call to :set guifont shows that things seem to have been set correctly, as it returns guifont=Lucida_Sans_Typewriter:h11:cANSI Then I manually select Edit-Select Font ... and then choose Lucida Sans Typewriter, and font size 11 and submit, the italics disappear and it looks fine. I've posted my _gvimrc for reference at http://vim.pastey.net/132157 So my questions are: Why am I getting different results from setting it manually and from _gvimrc? Is there a way to capture the command that the dialog box is sending back to the program? It might include extra commands that I'm missing.
