• Finding how a hacked server was hacked

  - by sixtyfootersdude

  I was just browsing through the site and found this question: My server's been hacked EMERGENCY. Basically the question says: My server has been hacked. What should I do? The best answer is excellent but it raised some questions in my mind. One of the steps suggested is to: Examine the 'attacked' systems to understand how the attacks succeeded in compromising your security. Make every effort to find out where the attacks "came from", so that you understand what problems you have and need to address to make your system safe in the future. I have done no system admin work so I have no idea how I would start doing this. What would be the first step? I know that you could look in the server log files but as an attacker the first thing that I would do would be errasing the log files. How would you "understand" how the attacks succeeded?

• Search ranking for important keywords has gone down drastically [duplicate]

  - by Vaivhav

  This question already has an answer here: How to diagnose a search engine ranking drop? 5 answers Firstly, we are a small entrepreneurial team of 3 persons and I am more like an amateur webmaster of the company's website as we cannot really afford a technical guy/department right now. A few weeks earlier, our website traffic and rankings for most keywords decreased overnight. I did a lot of reading henceforth and learned about Penguin 2.1 which people said is the reason for the drop. Something like this had never happened before. Now, I have gone through the entire Google webmaster help section. It says there that if a manual penalty is taken against us, we would notice a message in Manual Actions page. So far, we haven't received any notice from Google for web spam. Some SEO guys I contacted said they found spam links in our backlink profile. I do believe I had mistakenly purchased a cheap link/SEO scheme when I was yet very new to SEO. This was more than a year back but since then we have been legitimate. Moreover, how do I find out which is a spam link and which is not? Our content is all original, refreshing and the best you will find in our niche. We also have a blog but on a different domain (wordpress.com) from where we send out anchored links to our business website. Is this a good thing to do? Now, how should we proceed and recover our traffic/rankings. I tried searching in webmasters for a way to reach google and ask them why the traffic has decreased suddenly, but I couldn't find a contact form or something. Can someone please go through our website and help in making things more clear regarding the reason for the drop, along with a solution. Will really appreciate this as I can't get to figure this out and its taking a lot of time. Vaivhav

• Is dependency injection by hand a better alternative to composition and polymorphism?

  - by Drake Clarris

  First, I'm an entry level programmer; In fact, I'm finishing an A.S. degree with a final capstone project over the summer. In my new job, when there isn't some project for me to do (they're waiting to fill the team with more new hires), I've been given books to read and learn from while I wait - some textbooks, others not so much (like Code Complete). After going through these books, I've turned to the internet to learn as much as possible, and started learning about SOLID and DI (we talked some about Liskov's substitution principle, but not much else SOLID ideas). So as I've learned, I sat down to do to learn better, and began writing some code to utilize DI by hand (there are no DI frameworks on the development computers). Thing is, as I do it, I notice it feels familiar... and it seems like it is very much like work I've done in the past using composition of abstract classes using polymorphism. Am I missing a bigger picture here? Is there something about DI (at least by hand) that goes beyond that? I understand the possibility of having configurations not in code of some DI frameworks having some great benefits as far as changing things without having to recompile, but when doing it by hand, I'm not sure if it's any different than stated above... Some insight into this would be very helpful!

• Why can't anyone else access my website in IIS on Windows 7?

  - by Rod

  I've got an ASP.NET application that I have in IIS on my Windows 7 Ultimate machine. I've tested it from that machine and it works fine. This machine is in my home network, a simple peer-to-peer network. The strange thing is that no one else in my network can access that website. Why is that? There are other Windows 7 machines here, and they're all in the some homegroup. When I attempt to access the website on my machine from one of the other machines, it fails and that's it. So, what's wrong?

• Strange stuff in apache log

  - by aL3xa

  Hi lads, I'm building some kind of webapp, and currently the whole thing runs on my machine. I was combing down my logs, and found several "strange" log entries that made me a bit paranoid. Here goes: ***.***.***.** - - [19/Dec/2010:19:47:47 +0100] "\x99\x91g\xca\xa8" 501 1054 **.***.***.** - - [19/Dec/2010:20:14:58 +0100] "<}\xdbe\x86E\x18\xe7\x8b" 501 1054 **.**.***.*** - - [21/Dec/2010:15:28:14 +0100] "J\xaa\x9f\xa3\xdd\x9c\x81\\\xbd\xb3\xbe\xf7\xa6A\x92g'\x039\x97\xac,vC\x8d\x12\xec\x80\x06\x10\x8e\xab7e\xa9\x98\x10\xa7" 501 1054 Bloody hell... what is this?!

• Multiple monitors showing same screen but different resolutions

  - by Luis Alvarado

  Is it possible to have 2 or more monitors showing the same screen, for example the same desktop but with different resolutions. Like the clone option in Nvidia or the mirror option using the Display settings in Ubuntu but instead of showing the same output with the same resolution, the both show the same output using a resolution that is native for each monitor connected. In my case if I have a netbook that has max resolution of 1360x768 and a TV that has 1280x1024, the would both show the same desktop but each with their own resolution that is compatible for each device. This would help in trying to find a resolution that works on both monitors and in cases like a mini netbook and a huge TV it would solve issues like having max 800x600 in one monitor and min 1024x768 in the other. In the case I tested I was using an HDMI cable but this question also involves VGA and any other connection. I have 3 tests scenarios for this: Scenario 1 - Laptop HP DV6000 (Intel Integrated Video) with 1360x760 connected to a Samsung LED 42 TV that has 1280x900. Scenario 2 - Laptop EEE with 1024x600 (Intel Integrated Video) connected to Sony LCD TV that supports 1280x900. Scenario 3 - Intel Desktop with Nvidia 440 GT with HDMI connected to Soneview 32' TV that supports 1920x1080 and VGA connected to an Epson Video Beam that supports 1280x1024 max. In this 3 scenarios I need to be able to show the same desktop and same views but on different resolutions for each output device. UPDATE: Tested with Xubuntu and the way it handles multiple monitors is precisely what I am asking. The ability to handle the resolution of different monitors showing the same thing.

• What should a developer know before building a public web site?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web site address before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also: I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification. This question is community wiki, so please feel free to edit that answer to add links to good articles that will help explain or teach each particular point. To search in only the answers from this question, use the inquestion:this option.

• How to properly shutdown or reboot a Unix/Linux server

  - by hatorade

  What is the correct way to turn off a Unix/Linux server? From my googling, I have learned (hopefully) the following: shutdown: I should use this, with the parameter -h to halt, or the parameter -r to reboot halt: halts the computer (stops the processor? does this physically turn the power of the computer off?). I think this will call shutdown if not at init0, otherwise just halts. reboot: if not at init6, calls shutdown, otherwise just reboots the computer. if all that is correct, then the only thing I can't figure out is what exactly 'halt' does. Does it just stop the processor but not turn the computer physically off? How do I "poweroff" the computer? Thanks

• Heading Out to Oracle Open World

  - by rickramsey

  In case you haven't figured it out by now, Oracle reserves an awful lot of announcements for Oracle Open World. As a result, the show is always a lot of fun for geeks. What will the Oracle Solaris team have to say? Will the Oracle Linux team have any surprises? And what about Oracle hardware? For my part, I'll be one of the lizards at the OTN Lounge with the OTN crew, handing out t-shirts to system admins and developers, or anyone who is willing to impersonate one. I understand, not everyone can have the raw animal magnetism of a sysadmin, or the debonair sophistication of a C++ developer, so some of you have no choice but to pretend. I won't judge. I'll also be doing video interviews of as many techie people as I can corner. I've got more than 30 interviews already scheduled. Most of them will be 3-5 minutes long. I'll be asking our best technical minds what's cool about their latest technologies and what impact it will have on system admins or system developers. I'll be posting those videos here: Find OTN Systems Videos from Oracle Open World Here! We've got some great topics in mind. A dummies guide to hardware-assisted cryptography with Glenn Brunette. ZFS deduplication. The momentum building around Oracle Solaris 11, with Lynn Rohrer, plus conversations with partners who have deployed Oracle Solaris 11. Migrating to Oracle Database with SQL Developer. The whole database cloud thing. Oracle VM and, of course, Oracle Linux. So even if you can't be part of the fun, keep an eye out for the videos on our YouTube channel. - Rick Website Newsletter Facebook Twitter

• How to kick Jawbone ICON off iPhone to use with Mac

  - by SeniorShizzle

  I've got a Jawbone ICON, which is paired to my PS3, my Macbook Air, and my iPhone 4. Most of the time I'm using it with my Macbook with A2DP. The problem is that when I turn it on, my iPhone automatically connects to it, and hogs the A2DP profile, so then my Mac can't connect to the thing at all. I sort of like this behavior, so my best solution would be if there was some way to "kick" the ICONs connection to my iPhone from my Mac. It's really difficult because I use it alot with my Mac and my iPhone, so I can't delete one of the profiles, and I need to use A2DP on both devices. What are your suggestions on ways to fix this?

• How do you apply development practices like version control, testing and continuous integration/deployment to system administration?

  - by arex1337

  Imagine you're going to manage a number of servers with a number of different services that's used by a number of people. Now say you want to reconfigure or replace some software on one of those servers. Obviously you don't want to work on servers that are in production. If this was a code change, as a developer, I would make the change on my local development machine, test it locally and commit the change to a version control system. The changes could then be deployed in a staging environment, tested further and finally deployed in a production environment. It would also be easy for me to roll back, if necessary. Generally, or specifically, how do you achieve this in system administration? (The first thing that comes to mind is to use virtual machines and put virtual machine images in version control, but I'm sure there is a lot of literature and clever solutions I'm not presently aware of.)

• IIS 6 Ram Allocation on Windows Server 2003

  - by chris

  0 down vote favorite share [g+] share [fb] share [tw] I have my IIS 6 running my website. It is on a Windows Server 2003 which has 4GB of RAM. I run SQL intensive code after the user submits a form (math statistics stuff). This process is not threaded (should it be, especially if 2 or more users run the same thing?). But my process seems to consume only a couple of GBs of memory and the server crawls. How do I get my IIS process to use nearly all the memory? I see on other sites that its 2GB or 3GB allocated using boot.ini. But is there another way for the process to use memory? If I make it multithreaded, will there be a process for each thread?

• Selling your iphone games. [closed]

  - by Artemix

  Hi. So, long story short, some days ago I pusblished an iPhone game, I think the game wasnt that bad tbh, and still I got only 10 sells at $0.99. Are they any publishers, sponsors, or distributors to make your game "visible" on the app store market?, or the only thing you need is to have an amazing game and thats all? Somehow I think that even if you have an awesome game if you dont do that "marketing magic" correctly you will not exist in the store. Now Im making a second game, completly different, and I want to know how to do things right. If anyone knows something about this topic, let me know. Thx in advance.

• Home folder only SFTP connection has limited access

  - by Tomasz Durka

  I have configured sftp access for user using this guide: Linux shell to restrict sftp users to their home directories? I have problem though. I have taken all steps. I have chown'ed root:user the home folder and I set permissions to 755. I can login normally using SFTP, however I can NOT transfer files, can NOT mkdir directories. If I change permissions to 777 it's ok do edit everything. However this is the thing I don't want. Additionally after exiting sftp and reconnecting then connection is reset by peer (due to setting 777). Anyone had similar problem? What I am doing wrong?

• Rule of thumb for cost vs. savings for code re-use

  - by Styler

  Is it a good rule of thumb to always write code for the intent of re-using it somewhere down the road? Or, depending on the size of the component you are writing, is it better practice to design it for re-use when it makes sense with regards to time spent on it. What is a good rule of thumb for spending extra time on analysis and design on project components that have "some probability" of being needed later down the road for other things that may or may need this part. For example, if I have the need for project X to do things A, and B. A definitely needs to be written for re-use because it just makes sense to do so. B is very project specific at the moment, and I can hack it all together in a couple days to finish the project on time and give everyone kudos for being a great team, etc. Or if we say, lets spend a whole friggin' 2 weeks figuring out what project Y/Z might need this thing for and spend a load of extra time on on part B because someday we might need to use it on project Y/Z (where the savings will be realized). I'd imagine a perfect world situation would be a nicely crafted combination of project specific vs. re-use architected components given the project. However some code shops might feel it would be a great idea to write everything for the intention of using it at some point down the road.

• Is it possible to create a delta VM?

  - by iTayb

  I have a VM of approx. 18GB. Sometimes I need temporally clones of it, so I clone it. The problems are: * It takes a while until it's done. * Sometimes I happen to need dozen of clones and I'm running out of storage. I wonder if there's a way to create a VM that saves only the delta (difference) since the delployment out of the source machine. That way each new VM's filesize should be 100MB at most, and creating it will be much faster. I've heard that VMWare View is using this concept. Is such a thing possible for ESXi as well? I'm using ESXi 4.1 with VSphere 4.1. Thanks!

• Looking for Full Screen Web-Browser in Vizio or Samsung TV's

  - by ScottCate

  I see that Google TV, inside Sony, has a Chrome browser. Is the same thing possible inside Vizio, or Samsung, or any other TV? The 42" Vizio is $499 at Costco, and the Sony with Google TV is $999. We're looking at a buch of these TV's that have build in Wi-Fi, to place around the office as Big Dashboards, and I don't want to have a computer attached to get web content on the screen. It's my understanding that both Samsung Apps, and Vizio Apps, use Yahoo Widgets as their ap engine. Anyone know of a way to get a full screen browser going, without attaching a computer? We thought of attaching an Apple TV, which can be jailbroken, but that is just another piece of equipment to lose, break, etc. Thank you!

• Stuff you learned in school, that you have never used again?

  - by Mercfh

  Obviously we learn plenty of things in our University/College/Whatever that probably don't apply to everyday use, but is there anything that stands out particularly? Maybe something that was concentrated ALOT on? For me it was def. 2 things: OO Concepts and Pointers I still use OO, but not nearly to the amount people made it out to be, i can see where it'd be useful but in my line of work we don't have huge amounts of classes, maybe a couple at most. And there certainly isn't much OO reuse (i finally figured out what that means lol) Pointers are another thing, again I can see where they'd be useful...however I barely barely ever touch them, nor do the others I work with. I guess language choice has alot to do with that but still. What about you guys? edit: For those who are asking I work for a Large Printer company, and most of the Applications we work on are Java+XML and Actionscript for "Printer Apps". But we are moving towards other languages (think like webkits and stuff). So the Code amounts per parts are quite small. I never say OO wasn't useful I just said I personally havent seen it used in my workplace much.

• How do I trust an off site application

  - by Pieter

  I need to implement something similar to a license server. This will have to be installed off site at the customers' location and needs to communicate with other applications at the customers' site (the applications that use the licenses) and an application running in our hosting center (for reporting and getting license information). My question is how to set this up in a way I can trust that: The license server is really our application and not something that just simulates it; and There is no "man in the middle" (i.e. a proxy or something that alters the traffic). The first thing I thought of was to use with client certificates and that would solve at least 2. However, what I'm worried about is that someone just decompiles (this is build in .NET) the license server, alters some logic and recompiles it. This would be hard to detect from both connecting applications. This doesn't have to be absolutely secure since we have a limited number of customers whom we have a trust relationship with. However, I do want to make it more difficult than a simple decompile/recompile of the license server. I primarily want to protect against an employee or nephew of the boss trying to be smart.

• What can cause peaks in pagetables in /proc/meminfo ?

  - by Fuzzy76

  I have a gameserver running Debian Lenny on a VPS host. Even when experiencing a fairly low load, the players start experiencing major lag (ping times rise from 50 ms to 150-500 ms) in bursts of 3 - 10 seconds. I have installed Munin server monitoring, but when looking at the graphs it looks like the server has plenty of CPU, RAM and bandwidth available. The only weird thing I noticed is some peaks in the memory graph attributed to "page_tables" which maps to PageTables in /proc/meminfo but I can't find any good information on what this might mean. Any ideas what might be causing this? If you need any more graps, just let me know. The interrupts/second count is at roughly 400-600 during this period (nearly all from eth0). The drop in committed was caused by me trying to lower the allocated memory for the server from 512MB to 256MB, but that didn't seem to help.

• Baffling Exchange 2010 issue , Outlook 2003

  - by Nick Weber

  Recently we upgraded from Exchange 2003 to Exchange 2010. The Exchange 2003 server is still up and active with a handful of users still there we are planning on migrating. Also we have mobile devices and a Blackberry BES server setup publishing to Exchange 2010 public folders free busy. The unfortunate issue is majority of our clients are still Outlook 2003. The issue seems to be hit and miss but sometime clients cannot view other client’s calendars. They get (cannot refresh free/busy) when they add another user and check their available times. This is also true with booking resources (conference rooms) . One thing we noticed is that the Blackberry BES seems to have created its own free/busy folders, so we have some users who use the BES on free/busy folder and other users who don’t use the BES on other free/busy folders. If any of the clients log-in via “Exchange 2010” web-access or with a Outlook 2007 client they can view the calendaring just fine. Thanks for your help Nick @Toshana

• How can I tell GoogleBot that a subdirectory is now a subdomain?

  - by cwd

  I had about a million pages of a catalog indexed under a subdirectory, and now that's moved to a subdomain. GoogleBot is crawling each one of them and getting a 301 redirect to the new location. Even though I have set up the redirect rule in the apache sites-enabled configuration file, (i.e. it's early on when apache does the redirect - PHP is not even getting loaded), even though I have done that, the server isn't handling the load well. GoogleBot is making around 5 requests per second, and on top of my normal traffic that is hiking up the CPU for a few hours at a time. I checked in Webmaster Tools and the corresponding documentation for a way to let Google know that the content had been moved from a subdirectory to a subdomain, but with little luck. Basically the most helpful thing I saw said to just send 301 headers for the new location. How can I tell GoogleBot that a subdirectory is now a subdomain? If that is not an option, how can I more efficiently send 301 redirects out for a particular subdomain? I was thinking perhaps the Nginx server but I'm not sure that I can run both Apache and Nginx side by side on port 80 for different subdomains.
