  • Is man-in-the-middle attack a security threat during SSH authentication using keys?

    - by JP19
    Hi, I am no expert in network security, so pardon if this question is not very smart :). I am automating logins to some machines using ssh. I am currently avoiding host-key warnings using StrictHostKeyChecking no. I naively understand that someone can impersonate as the server and I risk losing my password to him if that were the case. However, if I am using only public/private Key based authentication ( using PasswordAuthentication no ), can the intruder still cause harm? So basically, with ssh -o "StrictHostKeyChecking no" -o "PasswordAuthentication no" : 1) Can the intruder decipher my private key? 2) Are there any other security threats? regards, JP

  • Debate: Can a HTTPS connection be hijacked with a man-in-the-middle kind of attack?

    - by Iulian Serbanoiu
    Hi, I'm wondering if the company I work for can see what I'm doing when I'm using a HTTPS connection - gmail for example. My case: I'm using gmail from work but I need to enter a password for a proxy when accesing the first web page - the password is asked inside the browser. I receive from the proxy a certificate which I must accept in order to make the Internet connection work. So the question is: Can https data exchange, between gmail and browser, be tracked? Thanks, Iulian

  • GNU info pages BLOW

    - by mbac32768
    How many times have you looked up a man page only to discover that it's useless and you're told to view the info page instead? Well, info is an abortion and I refuse to use it. How do you cope? Lets the healing begin. Curious if anyone has a nifty 'man' wrapper that auto-magically probes for an info document and converts that into a man page on-the-fly.

  • dead man's switch for remote networking interventions

    - by ascobol
    Hi, As I'm going to change the network configuration of a remote server, I was thinking of some security mechanisms to protect me from accidentally loosing control on the server. The level-0 protection I'm using is a scheduled system reboot: # at now+x minutes > reboot > ctrl+D where x is the delay before reboot. While this works relatevly well for very simple tasks like playing with iptables this method has at least two drawbacks: It's not very reactive, ie a connectivity problem should be detected automatically if for example an automatic remote ssh command fails does not work anymore for x seconds. It can obviously not work if one need to modify some configuration files and then reboot to test the changes. Are you guys using some tool for the second point ? I would love to have something able to revert the system configuration in a previously known stable state if I can't join the server X minutes after reboot. Thanks!

  • Using screen, commands like less and man don't clear the screen afterwards

    - by Boldewyn
    In contrast to this question I want the clearing of the screen re-enabled for less. It works fine in my xterm terminal under Cygwin/mintty or Gnome Terminal (both xterms). However, when inside a screen session, the clearing of the screen is somehow disabled. I tried several things, like screen -T xterm or putting the autonuke statement in my ~/.screenrc. Also, inside the screen session export TERM=xterm tset has no effect. So, now I'm out of ideas. Any help appreciated.

    - by NoCarrier
    I've got an environment with several IIS 6 web servers hosting hundreds of apps (dozens of sites, hundreds of virtual directories) all with a myriad of different configurations belonging to dozens of different developers (all deploying apps willy nilly). Is there some sort of managed software solution that will centralize management of all my IIS6 environments provide some inventory functionality allow for reporting or querying of said application inventory enforce and automate some sort of deployment process?

  • JavaOne in Brazil

    - by janice.heiss(at)oracle.com
    JavaOne in Brazil, currently taking place in Sao Paolo, is one event I'd love to attend. I once heard "father of Java" James Gosling talk about Java developers throughout the world. He observed that there were good developers everywhere. It was not the case, he said, that that the really good developers are in one place and the not-so-good developers are in another. He encountered excellent developers everywhere. Then he paused and said that the craziest developers were definitely the Brazilians. As anyone who knows James would realize, this was meant as high praise. He said the Brazilians would work through the night on projects and were very enthusiastic and spontaneous - features that Brazilian culture is known for. Brazilian developers are responsible for creating one of the most impressive uses of Java ever - the applications that run the Brazilian health services. Starting from scratch they created a system that enables an expert doctor in Rio to look at an X-Ray of a patient near the Amazon and offer advice. One of the main architects of this was Java Champion Fabinane Nardon the distinguished Brazilian Java architect and open-source evangelist. As she writes in her blog:"In 2003, I was invited to assemble a team and architect a Public Healthcare Information System for the city of São Paulo, the largest in Latin America, with 14 million inhabitants. The resulting software had 2.5 million of lines of code and it was created, from specification to production, in only 10 months. At the time, the software was considered the largest J2EE application in the world and was featured in several articles, as this one. As a result, we won the Duke's Choice Award in 2005 during JavaOne, the largest development conference in the world. At the time, Sun Microsystems make a short documentary about our work." "In 2007, a lightning struck twice and I was again invited to assemble a new team and architect an even larger information system for healthcare. And thus I became CTO and one of the founders of Zilics Healthcare Information Systems. "In 2010, I started to research and work on Cloud Computing technology and became leader of the LSI-TEC Cloud Computing group. LSI-TEC is a research laboratory in the University of Sao Paulo, one of the best in Brazil. Thus, I became one of the ghost writers behind the popular Cloud Computing Twitter @the_cloud."You can see and hear Nardon in a 4 minute documentary on Java and the Brazilian health care system produced by Sun Microsystems. And you can listen to a September 2010 podcast with Nardon and her fellow Brazilian Java Champion Bruno Souza (known in Brazil as "Java Man") here at 11:10 minutes into the podcast.Next year, I'll hope to be reporting in Brazil at JavaOne!

  • What does the -R flag do for chflags?

    - by ralphthemagician
    I'm not clear on exactly what the -R flag does for chflags. I was wondering if someone might be able to help me. The man page says this: Recurse: Change the file flags of file hierarchies rooted in the files instead of just the files themselves. I don't understand what that means. Can someone tell me what the difference would be between chflags -R hidden and just chflags hidden? There's an online man page here for reference: http://ss64.com/osx/chflags.html

  • is magento overkill for a one-man webshop?

    - by Rick J
    I have been looking at magento for a while and I think I have a decent handle on how to use/customize it. I have a client that wants a webshop , this is just a small business that sells a few products and just supports one language. I was wondering if using magento will be an overkill for a simple webshop , in case I cant help them to make future changes tp the webshop, the people running their business might have to do it. But it looks like magento is made for people with some technical know how (lots of xml editing etc).. So should i go for magento or a simpler solution like osCommerce or maybe even a simple custom solution. Would like to hear your opinions!

  • Man machine interface command syntax and parsing

    - by idimba
    What I want is to add possibility to interact with application, and be able to extract information from application or event ask it to change some states. For that purpose I though of building cli utility. The utility will connect to the application and send user commands (one line strings) to the application and wait for response from the application. The command should contain: - command name (e.g. display-session-table/set-log-level etc.) - optionally command may have several arguments (e.g. log-level=10) The question to choose syntax and to learn parse it fast and correctly. I don't want to reinvent the whell, so maybe there's already an answer out there.

  • Poor man's "lexer" for C#

    - by Paul Hollingsworth
    I'm trying to write a very simple parser in C#. I need a lexer -- something that lets me associate regular expressions with tokens, so it reads in regexs and gives me back symbols. It seems like I ought to be able to use Regex to do the actual heavy lifting, but I can't see an easy way to do it. For one thing, Regex only seems to work on strings, not streams (why is that!?!?). Basically, I want an implementation of the following interface: interface ILexer : IDisposable { /// <summary> /// Return true if there are more tokens to read /// </summary> bool HasMoreTokens { get; } /// <summary> /// The actual contents that matched the token /// </summary> string TokenContents { get; } /// <summary> /// The particular token in "tokenDefinitions" that was matched (e.g. "STRING", "NUMBER", "OPEN PARENS", "CLOSE PARENS" /// </summary> object Token { get; } /// <summary> /// Move to the next token /// </summary> void Next(); } interface ILexerFactory { /// <summary> /// Create a Lexer for converting a stream of characters into tokens /// </summary> /// <param name="reader">TextReader that supplies the underlying stream</param> /// <param name="tokenDefinitions">A dictionary from regular expressions to their "token identifers"</param> /// <returns>The lexer</returns> ILexer CreateLexer(TextReader reader, IDictionary<string, object> tokenDefinitions); } So, pluz send the codz... No, seriously, I am about to start writing an implementation of the above interface yet I find it hard to believe that there isn't some simple way of doing this in .NET (2.0) already. So, any suggestions for a simple way to do the above? (Also, I don't want any "code generators". Performance is not important for this thing and I don't want to introduce any complexity into the build process.)

  • Who Are the BI Users in Your Neighborhood?

    - by Brian Dayton
    Forrester's Boris Evelson recently wrote a blog titled "Who are the BI Personas?" that I enjoyed for a number of reasons. It's a quick read, easy to grasp and (refreshingly) focuses on the users of technology VS the technology. As Evelson admits, he meant to keep the reference chart at a high-level because there are too many different permutations and additional sub-categories to make such a chart useful. For me, I wouldn't head into the technical permutations but more the contextual use of BI and the issues that users experience.  My thoughts brought up more questions than answers such as: Context: -          HOW: With the exception of the "Power User" persona--likely some sort of business or operations analyst? -          WHEN: Are they using the information to make real-time decisions on the front lines (a customer service manager or shipping/logistics VP) or are they using this information for cumulative analysis and business planning? Or both? -          WHERE: What areas of the business are more or less likely to rely on BI across an organization? Human Resources, Operations, Facilities, Finance--- and why are some more prone to use data-driven analysis than others? Issues: -          DELAYS & DRAG ON IT?: One of the persona characteristics Evelson calls out is a reliance on IT. Every persona except for the "Power User" has a heavy reliance on IT for support. What business issues or delays does that cause to users? What is the drag on IT resources who could potentially be creating instead of reporting? -          HOW MANY CLICKS: If BI is being used within the context of a transaction (sales manager looking for upsell opportunities as an example) is that person getting the information within the context of that action or transaction? Or are they minimizing screens, logging into another application or reporting tool, running queries, etc.?   Who are the BI Users in your neighborhood or line of business? Do Evelson's personas resonate--and do the tools that he calls out (he refers to it as "BI Style") resonate with what your personas have or need? Finally, I'm very interested if BI use is viewed as  a bolt-on...or an integrated part of your daily enterprise processes?

  • What software development process should I learn first for a solo project?

    - by Omar Kohl
    I want to develop a project on my own (if it is sucessful more people might start working on it too). Also I want to apply some proper software engineering from the first until the last day. On one hand just to try it out and compare results with previous projects that were just about writing code quick and dirty, and on the other hand to learn! I know the proper answer to this question is "It depends very much on the project...", "There is no single correct answer...". But I just need someplace to start, somewhere where every step is written down and tells me what to do. If I'm not happy next time I'll try something else. So, how/where should I start? I would love to hear some book suggestions cause I'm all about books :-D.

  • Using an array as parameter to a class.

    - by Gabriel A. Zorrilla

In Man class, there is a OnClick method that opens a new window showing its name and age. public Man(){ Onclick(){ InfoWindow showinfo = new InfoWindow(this.getid()) // If this is Man[2] the id would be 2. } And in InfoWindow class: public class InfoWindow extends JFrame{ public InfoWindow(Man selectedMan){ setSize(300, 200); JLabel info = new JLabel(selectedMan.getname()); add(info); info.setVisible(true); } } Basically, that's wanna acomplish (show in pseudocode), pass a Man[i] into a class that when a window is created, shows the info related to that man. This is how i'm actualy trying to implement it but it's not working, i'm pretty sure there is a misconception from me in some part. Any help?

  • Remove key from known_hosts

    - by Adam Matan
    Hi, I have built several virtual machines during the last few weeks. The problem is, the .ssh/known_hosts gives me the Man in the middle warning. This happens because another fingerprint is associated with the virtual machine IP. In the .ssh/known_hosts file, however, I don't seem to find the record related to the IP, only two bizarre, key-like strings and "ssh-rsa". Any ideas how to remove the old key from known_hosts? Thanks, Udi

  • How to jump to a particular flag in a Unix manpage?

    - by dotancohen
    When reading a Unix manpage in the terminal, how can I jump easily to the description of a particular flag? For instance, I need to know the meaning of the -o flag for mount. I run man mount and want to jump to the place where -o is described. Currently, I search /-o however that option is mentioned in several places before the section that actually describes it, so I must jump around quite a bit. Thanks.
