• Proxying fake domain to a localhost port

  - by Trevor Burnham

  I'd like to do much the same thing described at Redirect Domain Name to Localhost for web app development purposes, but with the twist that I'd like requests to fakedomain.com:80 to be routed to localhost:8080, say, so that I don't have to actually use my development machine's port 80. I'd welcome answers that take the form of: Small changes to configuration files like /etc/hosts, and/or An easy-to-configure proxy server I could run Note: Pow takes the approach of setting a firewall rule to forward all incoming traffic on port 80 to port 20559. That may be an acceptable solution, but ideally, I'd like to forward only a specific domain + port combination.

• How to take a CSS animation from a browser, and export a GIF of it?

  - by Truth

  I have the following CSS3 Animation going on: http://dabblet.com/gist/2884702. It's basically a simulation of a mirror rotating on its x-axis. Now, I wish to present that in a PowerPoint presentation. Since PowerPoint doesn't have the webkit engine, I want to extract an animated GIF image of that animation, and embed it into my presentation. The problem? No matter what I've tried, I couldn't make a reasonably smooth animated GIF. I've Googled and found many free software which claim to do the job, tried several, none worked as expected. I've tried IrfanView, same issue (also their site makes me want to vomit). So, is there a solution? Or am I doomed to not be able to display it?

• Switching to LDAP over SSL for Active Directory

  - by bkildow

  On our active directory server, I would like to enable LDAP over SSL as per this: http://support.microsoft.com/kb/321051. I am wondering, once this is set up, will LDAP still be listening on the standard port, 389 once this is implemented as well as the secure port? Or will the secure port completely replace the standard port as an option to connect to? Also, will there need to be any other configurations besides the steps in the article for doing this? In other words, will domain users still be able to authenticate like normal, or is there additional setup that would need to occur?

• Interface to collect successful remote backups status

  - by Aseques

  I would like to deploy into our infrastructure a web interface that could register when the copies are finished and if for some reason they haven't. The current issue is that we are doing on site backups for customers, for each backup a mail is sent ad the end of the backup, the problems is that sometimes the mail isn't sent for a variety of reasons: System doesn't have internet Backup system crashed before sending the mail etc.. What I'd like to do is to have a web interface that the backup software cant visit after doing the backup (either if it's a success or a fail), that acknowledges that the backup has finished, after some time, I'd like to receive a report of the machines that hadn't done the backup. Is there anything remotely similar to this that I could use/adapt to our environment? UPDATE: Just found out this (paessler.com) that seems to be a privative solution of what I intended.

• Sendmail /etc/hosts and DNS ... what is the correct way?

  - by ben

  I found one tutorial on setting up sendmail that says that in the /etc/hosts file, "The entry for 127.0.0.1 must always be followed by the fully qualified domain name (FQDN) of the server." Like so: 127.0.0.1 bigboy.my-site.com localhost.localdomain localhost bigboy (This tutorial is here). However, I can't find anyone else suggesting something like that. instead most people seem to put some combination of localhost and localdomain.localhost after 127.0.0.1, and then some variant of the fully qualified domain name after the public ip address. What is the correct way?

• Merging Two Git Repositories with branches

  - by Joel K

  I realize there's a Stack Overflow question: http://stackoverflow.com/questions/277029/combining-multiple-git-repositories But I haven't found git-stitch-repo to be quite the tool I'm looking for. I also consider this more of a sysadmin task. How do I take code from an external repository and combine it with code from a primary repository while maintaining history/diffs and branches. Use case: An outside development team using SVN has ported to git and now wants to 'merge' their code in to the main company's git repo. I've tried subtree merges, but I lose the history. I've tried git-stitch-repo, but that process results in an entirely new repo that's missing branches. I just want to slot in some outside code as a sub-directory in our current main repo with as little disruption as possible and while maintaining the other project's history. Any success stories out there?

• Browser extension (or other software) to delay page load

  - by Doug Harris

  The alt text to today's comic at xkcd.com (strip below) says: After years of trying, I broke this habit in a day by decoupling the action and the neurological reward. I set up a simple 30-second delay I had to wait through, in which I couldn't do anything else, before any new page or chat client would load (and only allowed one to run at once). The urge to check all those sites magically vanished--and my 'productive' computer use was unaffected. (bold is my emphasis) Does anybody know of a browser extension or other software that will add this sort of delay? I've seen extensions which simply block sites, but not a delay like this.

• Which Power supply I should buy

  - by arayman

  I am going to buy a new PSU of CORSAIR for my IBM thinkcentre desktop. My previous original PSU was of 230 watts. I have not added any hardware in the CPU.

On that basis, please suggest which power supply of Corsair and of how many watts will be suitable for me to buy, after referring to the under given weblink. http://www.corsair.com/en/power-supply-units.html Thanks.

• Why does the task pictogram flashes instead of opening the program?

  - by fredley

  Sometimes, when I select a click a program on the Windows 7 taskbar it won't appear (it doesn't gain focus and remains behind other open windows), and the icon will flash and turn orange. This happens reasonably frequently, and I've had it happen on two separate Windows installs on different machines. It just happened now and the only programs I have with active windows are Chrome, WMP and Explorer (2). It happened when I clicked Explorer. Once this has happened to one window, it affects all windows, and the only way I can switch between programs is by finding the window manually or using Windows+Tab. The only way I've come across to get the computer to snap out of this annoying behaviour is to restart the machine. Is there a way of stopping it? Edit Here's a video of it happening: http://www.youtube.com/watch?v=P12OxKK0kM4

• In Nginx, can I handle both a location:url or a content-type: text/html response from memcached?

  - by Sean Foo

  I'm setting up an nginx - apache reverse proxy where nginx handles the static files and apache the dynamic. I have a search engine and depending on search parameter I either directly forward the user to the page they are looking for or provide a set of search results. I cache these results in memcached as key:/search.cgi?q=foo value: LOCATION:http://www.example.com/foo.html and key:/search.cgi?q=bar value: CONTENT-TYPE: text/html <html> .... .... </html> I can pull the "Content-type...." values out of memcached using nginx and send them to the user, but I can't quite figure out how to handle a returned value like "Location..." Can I?

• Google Chrome and kerberos authentication against Apache

  - by Lars

  I've managed to get kerberos authentication to work now with Apache and Likewise Open but so far, Google Chrome doesn't seem to play fair. Unless I start it with chrome.exe --auth-server-whitelist="*company.com" it does only pop-up a login window but will not accept any credentials at all. As far as I know, the --auth-server-whitelist option should only be used when trying to get Single-Sign-On (SSO) to work, but if you are fine with a log-in window it should work directly out of the box, but so far it doesn't. This is the error I get in the apache logs. [Tue Dec 13 08:49:04 2011] [error] [client 192.168.1.15] failed to verify krb5 credentials: Unknown code krb5 7

• a load balancing scenario using HAProxy and keepalived shows no performance advantage

  - by chakoshi

  Hi, I am trying to setup a load balanced web server scenario, using two HAproxy load balancers and two debian web servers following this guide http://www.howtoforge.com/setting-up-a-high-availability-load-balancer-with-haproxy-keepalived-on-debian-lenny. the setup is working but the results of simple performance benchmarking is not what I expected. I tried apache benchmark tool to send lots of requests to servers (one time directly testing one of the web servers and the other time testing through the load balancer) using the command "ab -n 1000000 -c 500 http://IP/index.html", but the test results shows better performance for the single server without load balancer. can any one tell me if I'm going wrong on some thing?

• How to make the free Microsoft Virtual Hard Disk image to work with VirtualBox's simulated network c

  - by Jian Lin

  I have a Macbook Pro at work and installed the current VirtualBox (3.2.4) today. However, after using the VHD image for IE 7 on XP SP3 on this: http://www.microsoft.com/downloads/details.aspx?FamilyID=21eabb90-958f-4b64-b5f1-73d0a413c8ef&displaylang=en The Virtual Operating System (XP) just thought there is no network card provided by the PC (the virtual PC simulated by VirtualBox), even if I set up 4 network cards in Settings, as NAT, host only, etc. So the XP cannot browse any webpage at all... Does any integration package need to be added for VirtualBox to make it work and how? (is VirtualBox providing a "too advanced" network card so XP SP3 doesn't have the driver for it? thanks.

• Why are some PNGs open in Photoshop with Indexed Colors and no transparency?

  - by Daniel Beardsley

  Why are some 32 bit PNGs opened in Photoshop with Indexed Colors and no transparency? For instance, I grabbed a png icon file of the Stack Overflow logo at: http://blog.stackoverflow.com/wp-content/uploads/icon-so.png When opening it in Photoshop CS3, it apparently treats it as indexed color and gets rid of the alpha channel. The image on the right is a screen grab of the icon. Changing the Image mode in Photoshop to RGB doesn't change the image at all. I've tried this with a few other PNGs and it seems hit or miss. When viewed in other programs, it displays fine. left:png opened in Photoshop, right:screen grab of png from browser What gives?, does Photoshop not interpret the PNG file format correctly?

• impossible to connect.. days trying..

  - by dany

  I have a problem: I am on Debian. I configured my nic with a static ip (192.168.1.56). When I try to connect to a network, initially with ifconfig eth2 I get (correctly): eth2 inet addr:192.168.1.56 .... inet6 addr: fe80:221:ff:fe96:4598/64 but after a few seconds the 102.168.1.56 disappears and after some other seconds disappears the inet6 address too. When I press in the nm-applet it requires me the password but in the meantime it try to connect. At uni, the connection is a DHCP one. It works for the first few seconds but after it doesn't. Any possible solution? Here it is the relevant part of the syslog: (static ip configuration) http://pastebin.com/u3BPAsda

• Can I directly open an MMF Cash Drawer through RJ-11 port?

  - by roviuser

  My aunt bought this cash drawer at an auction recently and has tasked me with figuring how to open it via a computer. We have the key (pictured) and can open it manually, but I'd like to be able to plug it directly into a computer and open it via some sort of program or script. It has a built in rj-11 cord coming out of the back of it. Initial research shows that it might usually be used with a printer, but I want to be able to connect it directly to the computer. Edit: this needs to be able to work with windows 7. Edit2: http://imgur.com/a/czEMs imgur gallery of the innards.

• Where to obtain openssl-devel for SunOS 5.10

  - by user35949

  So I am having an issue that I have seen other people have on many different systems. I have to build Subversion on a SunOS 5.10 box and have run into issues. I have the openssl source code installed and in the subversion-1.6.9 folder, I run the following: ./configure --with-ssl --with-libs=/opt/exp/lib/openssl/lib and receive the error: checking for library containing RSA_new... not found configure: error: could not find library containing RSA_new configure failed for neon I have also tried running the command without the "lib" on the end of the --with-libs path. I read online that I need the openssl-devel packages, but I have been unable to find them for SunOS 5.10, and they do not show up already installed on my system when running pkginfo. I have looked online including http://www.sunfreeware.com/ which I was told was a good SunOS software source. Any help you can provide would be welcomed. Thanks, Sean

• How can I whitelist a user-agent in nginx?

  - by djb

  I'm trying to figure out how to whitelist a user agent from my nginx conf. All other agents should be shown a password. In my naivity, I tried to put the following in before deny all: if ($http_user_agent ~* SpecialAgent ) { allow; } but I'm told "allow" directive is not allowed here (!). How can I make it work? A chunk of my config file: server { server_name site.com; root /var/www/site; auth_basic "Restricted"; auth_basic_user_file /usr/local/nginx/conf/htpasswd; allow 123.456.789.123; deny all; satisfy any; #other stuff... } Thanks for any help.

• Rsync and Windows 7

  - by Nate

  Can someone give me any tips on setting up some sort of Rsync server/client on Windows 7 to run rsync between both my web hosting server, and a backup server that I have running Ubuntu? I've tried setting it up with this tutorial: http://www.youtube.com/watch?v=CvwdkZLNtnA Using copssh, and cwrsync. Ran into all sorts of troubles, including not being able to get cwrsync to run (it installs properly, but never starts up), and copssh not generating the keys at all. The guy was running Windows Server 2003, though, so I'm guessing the problems could just be because I'm running Windows 7. I've been trying to set it up with my Windows machine being the rsync server, and then Ubuntu and my webhosting VPS as the clients, but I realize it may be easier (and make more sense) to just setup the rsync server on Ubuntu, and then an rsync client on Windows 7? Can anyone point me in the right direction? I'm thinking of using this guide: http://www.gaztronics.net/rsync.php It seems a bit outdated, though.

• Rename outlook2007 categories not working

  - by Bob Rivers

  Hi, I'm new to outlook 2007 and I'm trying to rename a category. Acordingly to MS, I can achieve it by just renaming it: http://office.microsoft.com/en-us/outlook/HA012316361033.aspx But as soon as I click the OK button, confirming the change, it returns to it's original value. For instance, if I rename the "Blue Category" to "Home" it will accept without erros. But, when I click again in the Categorize icon, I'll see that the "Blue Category" is still there, and my "Home" category does not exist. Has someone experienced this kind of problem? TIA, Bob

• 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?

• Should I anticipate any problems trying to use the same SSL Cert on 2 computers (primary, backup)?

  - by Matt

  We have a production machine running IIS6 with a wildcard SSL certificate. The certificate that was installed is not exportable. We want to upgrade the system to IIS7. As part of this venture, we're creating a backup/failover server that will serve the exact same websites - when we take the primary down for upgrade, the secondary will take over. As such, the secondary also needs the SSL certificate. However, since the certificate was not exportable, this means re-keying it from Go Daddy. Per http://help.godaddy.com/article/867, I know that by re-keying the certificate the original will stop working. I'm still pretty new to SSL certificates, so are there any problems I should anticipate when installing the same SSL certificate on 2 different machines?

• AXFR problem using gradwell secondary DNS

  - by Roaders

  Hi All I use Gradwell.com to provide secondary DNS but I keep getting e-mails along the lines of the following saying that it's not working: You have asked us to provide a secondary DNS service for the following domain(s) Unfortunately, the primary DNS server(s) you specified are not permitting the necessary zone transfers from our servers, or they are not answering "SOA" queries for your domain correctly. I have gone through the support procedure and they weren't that helpful. They have suggested the following: Our secondline team have suggested setting the AXFR to use anouther machine. This will ensure that the transfer is not locked down to one machine and should allow any machine to make the request I don't really know what AFXR is and I only have 1 production machine so I can't set the AFXR to use another one! In previous support correspondence we confirmed that I am allowing transfers to the correct IP and that I have the correct ports open on the firewall. I am running Windows Server 2003. What can I do to try and get these zone transfers working? Thanks
