• Terminal Server 2003 Performance Troubleshooting

  - by MikeM

  Let me get your thoughts on terminal server performance problems. The server hosts average 25 users which, after running some numbers, on average use 600MB memory with their main applications running (web browser, adobe reader, IP phone client). All users are on the same LAN as server. We constantly experience slow response and short session lockups. Combined CPU usage is on average 10%. What appears strange to me is that the system shows 29GB physical memory with 25GB of it free. The page file usage is about 50% averaging 9GB used. Some server specs OS: Server 2003 32bit Enterprise with /PAE flag RAM: 32GB CPU: 2xQuad Core @ 2.27Ghz HD: RAID5 1.2GB After doing basic troubleshooting using performance monitor it leads me to believe that the performance problems are caused by the 32bit OS limitation in addressing full 32GB of physical memory even though the /PAE flag is used. Can anyone suggest something, troubleshooting steps that can lead to a more conclusive answer? Thanks

• iptables: How to combine DNAT and SNAT to use a secondary IP address?

  - by Que_273

  There are lots of questions on here about iptables DNAT/SNAT setups but I haven't found one that solves my current problem. I have services bound to the IP address of eth0 (e.g. 192.168.0.20) and I also have a IP address on eth0:0 (192.168.0.40) which is shared with another server. Only one server is active, so this alias interface comes and goes depending on which server is active. In order to get traffic accepted by the service a DNAT rule is used to change the destination IP. iptables -t nat -A PREROUTING -d 192.168.0.40 -p udp --dport 7100 -j DNAT --to-destination 192.168.0.20 I also wish all outbound traffic from this service to appear to come from the shared IP, so that return responses will work in the event of a active-standby failover. iptables -t nat -A POSTROUTING -p udp --sport 7100 -j SNAT --to-source 192.168.0.40 My problem is that the SNAT rule is not always run. Inbound traffic causes a connection tracking entry like this. [root]# conntrack -L -p udp udp 17 170 src=192.168.0.185 dst=192.168.0.40 sport=7100 dport=7100 src=192.168.0.20 dst=192.168.0.185 sport=7100 dport=7100 [ASSURED] mark=0 secmark=0 use=2 which means the POSTROUTING chain is not run and outbound traffic leaves with the real IP address as the source. I am thinking I can set up a NOTRACK rule in the raw table to prevent conntracking for this port number, but is there a better or more efficient way to make this work? Edit - Alternative question: Is there a way (in CentOS/Linux) to have an interface that can be bound to but not used, such that it can be attached to the network or detached when a shared IP address is swapped between servers?

• Nginx 502 Bad Gateway: It just won't stop

  - by David

  I have the same problem that most people seem to have with Nginx: 502 bad gateway errors. They are intermittent but typically happen more than once per session, which means my users are probably running into it nearly every time they use the app. I've tried adjusting fastcgi_buffers and fastcgi_buffer_size (in both directions) to no avail. I've tried various other things with the configuration file but nothing seems to work. Here's my config (note that I've stripped away most of the things I've tried, since they didn't work and I didn't want to bloat the file with a bunch of un-related directives): server { root /usr/share/nginx/www/; index index.php; # Make site accessible from http://localhost/ server_name localhost; # Pass PHP scripts to PHP-FPM location ~ \.php { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; } # Lock the site location / { auth_basic "Administrator Login"; auth_basic_user_file /usr/share/nginx/.htpasswd; } # Hide the password file location ~ /\. { deny all; } client_max_body_size 8M; } I'm running a small Rackspace cloud server, which should be plenty for handling an app with a small user base...

• I/O intensive MySql server on Amazon AWS

  - by rhossi

  We recently moved from a traditional Data Center to cloud computing on AWS. We are developing a product in partnership with another company, and we need to create a database server for the product we'll release. I have been using Amazon Web Services for the past 3 years, but this is the first time I received a spec with this very specific hardware configuration. I know there are trade-offs and that real hardware will always be faster than virtual machines, and knowing that fact forehand, what would you recommend? 1) Amazon EC2? 2) Amazon RDS? 3) Something else? 4) Forget it baby, stick to the real hardware Here is the hardware requirements This server will be focused on I/O and MySQL for the statistics, memory size and disk space for the images hosting.

• How do I set a default host for nginx?

  - by ulf

  I'm trying to figure out how to set a default host for my nginx installation. I found this article in the nginx Wiki: http://wiki.nginx.org/NginxVirtualHostExample#A_Default_Catchall_Virtual_Host Unfortunately, this doesn’t work. After restarting I get this: Restarting nginx: nginx: [emerg] unknown directive "http" in /etc/nginx/sites-enabled/catchall:1 nginx: configuration file /etc/nginx/nginx.conf test failed After removing the http directive I get this: Restarting nginx: nginx: [emerg] unknown log format "main" in /etc/nginx/sites-enabled/catchall:7 nginx: configuration file /etc/nginx/nginx.conf test failed I’m on Ubuntu 10.04.3 where I’m using the official nginx PPA. Version 1.0.9 of nginx is running.

• Environment variables in Weblogic Managed Server with SSL nodemanager

  - by Eric Darchis

  We have a C legacy application start with JNI that requires environment variables. Not java -Djava.library.path -Dvar=foo as these are purely java. I need real environment variables. When we setup our domains, we usually use the SSH method to start the node managers. This works fine and the env variables are set properly. Recently the sysadmin has decided for a few reasons to use the SSL mode for nodemanagers. The servers start but the environment variables are not set. I checked with "pargs -e" (this is a Solaris machine) that the env variable was indeed not present from the nodemanager and for the managed server. Is SSL starting the managed server without running the .sh scripts or I am missing a parameter somewhere ?

• Starting Powerpoint show from ActiveX button

  - by Mike Shakespeare

  I have several slide shows where topic related shows are launched from another show which acts as an index page. This worked fine in 2007 but now in Office 2010, whilst the show is still launched correctly from the index button, Powerpoint reopens on top of it, so now the show is hidden behind the Powerpoint startup page. Its very annoying, does anyone have any idea what is going on? Regards avondata

• Using secure proxies with Google Chrome

  - by cYrus

  Whenever I use a secure proxy with Google Chrome I get ERR_PROXY_CERTIFICATE_INVALID, I tried a lot of different scenarios and versions. The certificate I'm using a self-signed certificate: openssl genrsa -out key.pem 1024 openssl req -new -key key.pem -out request.pem openssl x509 -req -days 30 -in request.pem -signkey key.pem -out certificate.pem Note: this certificate works (with a warning since it's self-signed) when I try to setup a simple HTTPS server. The proxy Then I start a secure proxy on localhost:8080. There are a several ways to accomplish this, I tried: a custom Node.js script; stunnel; node-spdyproxy (OK, this involves SPDY too, but later... the problem is the same); [...] The browser Then I run Google Chrome with: google-chrome --proxy-server=https://localhost:8080 http://superuser.com to load, say, http://superuser.com. The issue All I get is: Error 136 (net::ERR_PROXY_CERTIFICATE_INVALID): Unknown error. in the window, and something like: [13633:13639:1017/182333:ERROR:cert_verify_proc_nss.cc(790)] CERT_PKIXVerifyCert for localhost failed err=-8179 in the console. Note: this is not the big red warning that complains about insecure certificates. Now, I have to admit that I'm quite n00b for what concerns certificates and such, if I'm missing some fundamental points, please let me know.

• Converting massive images to PDF, without crashing applications

  - by BloodyIron

  I'm trying to work with a large-format scanner, and we are scanning very long documents. Example, one of our documents we cut into two pieces, and one of those pieces is 3633x82486 in resolution. My application, Scanning Master 21+, which comes with the device (Graphtec CSX300-09) can output PDF, however when I try to save to PDF it complains about file being too large. I can successfully output to BMP however. GIMP can even open this BMP, after taking a while to load it. The resulting files range from 200MB - 1.2GB in size. Acrobat refuses to open the BMP format, saying it isn't supported or is damaged (which I know is not true). As I mentioned, the PDF plugin for GIMP crashes when I try to export to PDF. I'm really not sure what is the best tool for this job. So what is the best tool to produce PDF documents of very large images?

• MS Excel find and replace macro

  - by william

  I have written a macro to remove special characters in a sheet based on ascii values but the problem with it is that it is replacing the cell content. For example p;j;h which should become p,j,h is becoming ,, (missing the data). Do I need to include any additional statements, or how else to adjust my code? sub specialcharecters() Dim i As Long For i = 32 To 43 Selection.Replace what:=Chr(i), replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next i Selection.Replace what:="~*", replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False For i = 45 To 47 Selection.Replace what:=Chr(i), replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next i For i = 58 To 64 Selection.Replace what:=Chr(i), replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next i For i = 123 To 125 Selection.Replace what:=Chr(i), replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False Next i Selection.Replace what:="~~", replacement:=", ", LookAt:=xlPart, SearchOrder:= _ xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False END sub

• Can I set a hyperlink's display text from a document property?

  - by themel

  I'm trying to make a word document customizable through a document property that contains the base URL of all the links. I've managed to make the links themselves reference the document property like this: { HYPERLINK { QUOTE "http://{ DOCPROPERTY Host}/some/path" } } Changing the document property and updating the files makes the hyperlinks point to the correct URL. However, visually, nothing changes - the old URL is still shown as the display text of the hyperlink. Is there a way to make this work? Microsoft docs helpfully state You can edit the display text for the field by typing over it. but I can't figure out how that is supposed to work - even if I manually type over the hyperlink, it includes the edits in the field code instead of adjusting the display text. Currently attempting in Word 2002, but 2010 also available.

• Problems with 5.1 digital out on Ubuntu 12.04

  - by user895319

  I've recently bought a new PC, installed Ubuntu and am now unable to get 5.1 digital sound working. Simple analogue stereo works fine on both the front and rear connectors. On my old box I connected the coax connection from my soundcard to my surround sound amplifier, set Settings-Sound to "Digital Stereo Duplex" and it worked. My old soundcard doesn't fit in my new machine so I'm using the built-in sound hardware. I'm connecting the combination output socket on the back of the PC via the same cable to my surround amp as before. The MB is an MSI Global H61M-P31 with an RealTek ALC887 sound chip. When I go to Settings-Sound I only see "Headphone Built-in Audio" and "Analogue Output Built-in Audio" - no digitial options. The output from aplay -l is: default Playback/recording through the PulseAudio sound server sysdefault:CARD=PCH HDA Intel PCH, ALC887-VD Analog Default Audio Device front:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog Front speakers surround40:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers dmix:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog Direct sample mixing device dsnoop:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog Direct sample snooping device hw:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog Direct hardware device without any conversions plughw:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Analog Hardware device with all software conversions While googling for ALC887 I've seen some references to "ALC887 -VD Analog" and some to "ALC887 -VD Digital".

• Formula to search for a value in a range of cells

  - by Sacha

  I have a spreadsheet with several cells in one column. Each cell has identical conditional formatting: In 1 cell value equal to ='Y' In 2 cell value equal to ='N' In 3 cell value equal to ='?' What I would like to achieve is, if all 7 cells contain "Y" as the option then a separate cell will display "Yes", but if any of the cells contain "N" as the selection then the separate cell will display "NO". How can I achieve this?

• Run batch on files in a relative folder

  - by Matteo Cuellar Vega

  I have a windows batch script that runs a SOX command on various files, but I don't know how to get the batch to run on files in a relative path to that of the SOX executable. Currently all the files are in the root and it outputs to /combined. The Batch Script: cd %~dp0 mkdir combined FOR %%A IN (*.mp3) DO sox static.mp3 %%A "combined/%%~nxA" pause I want the script to run the sox command on files in the directory "audiotracks" and output it to the directory "combined". To give you an idea, this would be the desired folder structure: /root sox.exe batch.bat static.mp3 /audiotracks audio1.mp3 audio2.mp3 audio3.mp3 audio4.mp3 /combined audio1out.mp3 audio2out.mp3 audio3out.mp3 audio4out.mp3 Is this possible, or is there a better method of doing this? Any help would be greatly appreciated. Thanks a lot!

• Ways to remotely reboot a Linux system

  - by dualed

  I had a remote server running Debian Sarge that experienced some HDD failure and I meant to reboot it hoping that fsck could repair the errors automatically. I eventually drove out there and replaced the faulty disks... But I was wondering: What other ways are there to force a Linux system to reboot that do not require hard drive access? What I had tried: shutdown -r now Did not work, as shutdown is a program that would have to be loaded from disk, the error shown in the terminal was bash: /sbin/shutdown: Input/output error init 6 same as above telinit q same as above kill -2 1 This did not print an error, but did not work either. (However, it is possible that the Sarge init did not implement SIGINT, the sarge manpages did not mention it. So it could work in a more recent version of Debian) This guide on PCFreak.net. However, this failed at sysctl, which was not in memory either.

• Installing Windows 7 from USB on a Thinkpad T61

  - by Halik

  I am trying to install Windows 7 Professional from USB 3.0 flashdrive, on a Thinkpad T61. The problem is, Thinkpads BIOS will not detect the flash drive as bootable medium, and won't allow to boot from it. What I did: Enabled USB BIOS Support in BIOS (it was on by default) In startup menu, added USB HDD to boot order (it has '-' sign in front of it) Created Windows 7 install media with UNetbootin, WinUSB (linux tool) dd and Grub4DOS. As you can tell, currently, I only have access to Linux machine to make the flashdrive. What happens: The T61 BIOS shows '-USB HDD' in boot order menu. The '-' sign suggests that the plugged flash drive is currently not bootable. The same flashdrive (with the same Windows image on it) is booting without any problems on a Dell D430 and Lenovo Y550. Also, Ubuntu 12.04 install USB created with Unetbootin shows as bootable ('+' sign in BIOS boot order menu) and boots from the F12 boot menu. Additional info thinkwiki.org says that some Thinkpad BIOSes do not use MBR on flashdrives. It suggests using Extended-IPL boot loader, but the provided links are broken and there seems to be no mirrors. Solution: http://superuser.com/a/430186/54970

• How to enable extension when running Firefox for the first time?

  - by spektom

  I need to run Firefox each time in a new profile directory with my extension enabled. What I do is the following: Create temporary directory for storing profile (/tmp/profile.123) Create extensions directory (/tmp/profile.123/extensions) Create extension proxy as described here (/tmp/profile.123/extensions/[email protected]) My command line looks like this: firefox -no-remote -profile /tmp/profile.123 -url http://www.google.com The problem is that my extension starts disabled, and I'm forced to enable it manually and restart the Firefox. Is it possible to make it start enabled in first place? Thanks! Workaround I've found: Create extensions.sqlite database file in the newly created profile folder. This file must contain my extension entry under the "addon" table.

• How to charge an iPhone on a Windows PC without Installing iTunes

  - by Martin Hollingsworth

  I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

• The Most Ridiculous Computer Cameos of All Time

  - by Jason Fitzpatrick

  For the last half century computers have played all sorts of major and minor roles in movies; check out this collection to see some of the more quirky and out-of-place appearances. Wired magazine rounds up some of the more oddball appearances of computers in film. Like, for example, the scene shown above from Soylent Green: Spoiler alert: Soylent Green is people! But that’s not the only thing we’re gonna spoil. Soylent Green is set in 2022, and at one point, you’ll notice that a government facility is still using a remote calculator that plugs into the CDC 6600, a machine that was state-of-the-art in 1971. Come to think of it, we should scratch this from the list. This is pretty close to completely accurate. Hit up the link below to check out the full gallery, including a really interesting bit about how the U.S. Government’s largest computer project–once decommissioned and sold as surplus–ended up on the sets of dozens of movies and television shows.

• How To Enable Do Not Track In Every Web Browser

  We’ve covered why “Do Not Track” isn’t a silver bullet that prevents you from being tracked. However, if you don’t like being tracked and want to express that preference to websites, you can enable “Do Not Track” in every browser. To Google’s credit, future versions of Chrome explain exactly what Do Not Track does when you enable it. Remember that, by enabling Do Not Track, you’re just expressing a preference.

controlled by the parameter _AUTO_MANAGE_EXADATA_DISKS. The default value for this parameter is TRUE.When _AUTO_MANAGE_EXADATA_DISKS is enabled, Exadata automate the following disk operations:If a griddisk becomes unavailable/available, ASM will OFFLINE/ONLINE it.If a physicaldisk fails or its status change to predictive failure, for all griddisks built on it ASM will DROP FORCE the failed ones and DROP the ones with predictive failures.If a flashdisk performance degrades, if there are griddisks built on it, they will be DROPPED FORCE in ASM.If a physicaldisk is replaced, the celldisk and griddisks will be recreated and the griddisks will be automatically ADDED in ASM, if they were automatically dropped by ASM. If you manually drop the disks, that will not happen.If a NORMAL, ONLINE griddisk is manually dropped, FORCE option should not be used, otherwise the disk will be automatically added back in ASM. If a gridisk is inactivated, ASM will automatically OFFLINE it.If a gridisk is activated, ASM will automatically ONLINED it.

• Integrating JavaFX Scene Builder in the IDEs

  - by Jerome Cambon

  I experienced recently using Scene Builder from Netbeans, Eclipse and IntelliJ IDEA. As you may know, Scene Builder is a standalone tool, that can be used independently of any IDE. But it can be very convenient to use it with your favorite IDE, for instance start it by double-clicking on an FXML file, or run samples delivered with Scene Builder.  I'm sharing here with you few tweaks that I had to do for a better integration. Scene Builder 1.1 Developer Preview should be installed before doing the tweaks. The steps below have been done on Windows 7. It should be very similar on both Mac OS and Linux. Please tell me if you find any issue on one of these 2 platforms. Netbeans 7.3 Netbeans 7.3 can be downloaded from here. Creating a New FXML project Part of the JavaFx projects, Netbeans allows to create a 'JavaFX FXML Application', that creates a JavaFx project based on FXML description. The FXML file will be editable with Scene Builder. Starting Scene Builder from Netbeans If SceneBuilder 1.1 is installed, Netbeans will discover it automatically.In case of issue, one can open the Options panel, Java section, JavaFx tab. Scene Builder home should appear here. You can then either Open the FXML file with Scene Builder, or edit it with the Netbeans FXML editor : When 'Open' is selected, Scene Builder appears on top of the Netbeans window : When 'Edit' is selected, the FXML is opened in the Netbeans FXML editor, which support syntax highlighting and completion : Using Scene Builder Samples Scene Builder provides Netbeans projects, that can be opened/run directly : Eclipse 4.2.1 + e(fx)clipse 0.1.1 JavaFX integration in Eclipse has been done with the e(fx)clipse plugin. A distribution bundle containing Eclipse and e(fx)clipse is provided here. Creating New FXML project All the JavaFX-related projects can be found in 'Other' section : First create a new JavaFX project: Enter the project name (Test here). JavaFX delivery will be found in the JRE. Then, create a 'New FXML Document': Enter the FXML file name (Sample here). You may also want to choose the FXML document root element (AnchorPane by default). Dynamic root is for advanced users which want to manage custom types. Starting Scene Builder from Eclipse Once created, you can then either Open the FXML file with Scene Builder, or Open it in the Eclipse FXML editor : Using Scene Builder Samples from Eclipse To use Scene Builder samples, first create a new JavaFX Project (from 'Other' section): Then, on the next panel, 'Link additionnal source': … and select the source directory of a Scene Builder example : HelloWorld here (the parent directory of the java package should be selected).Then, choose a 'Folder name' for your sample: You can now run the Scene Builder example by right-clicking the Main.java source file: IntelliJ IDEA 11.1.3 IntelliJ IDEA Community Edition can be downloaded from here. IntelliJ IDEA has no specific JavaFX integration. Creating New IntelliJ project from existing source Since IntelliJ has no JavaFX project knowledge, we are using the Scene Builder samples as a starting point. We are going to create a new Java project from the HelloWorld sample: Then, click twice on 'Next' (nothing to change), then 'Finish'. The 'HelloWorld' project is created. Starting Scene Builder from IntelliJ We need to tell the IDE that FXML files are opened with an external application. Then, the OS file association will be used. To do this, open the File->Settings panel. Then, select 'File Types' and 'Files opened in associated applications'. And add a new wildcard : '*.fxml' : Now, from the HelloWorld project, you can double-click on HelloWorld.fxml : Scene Builder window appears on top of the IntelliJ window : Using Scene Builder Samples from IntelliJ We need to tell IntelliJ that the fxml files must be copied in the build directory.To do that, from the HelloWorld directory, open the 'idea' section, and edit the 'compiler.xml' file. We need to add an '*.fxml' entry: Then, you can run the sample from HelloWorld project, by right-clicking the Main class:
