security - Is this a valid way to hack into Facebook applications? (and possibly Facebook)? -

-

  1. Your friend joins Facebook and "remembers me".
  2. Facebook makes a cookie
  3. Your friend goes to the bathroom.
  4. You steal your friend's cookies from your browser and its data.
  5. You go home and make cookies with that data.

Facebook is not affiliated with cookies + IP , then you can access Facebook page. EDIT: True, Facebook does not check for IP.

Now, let's look at Facebook Connect. This is the key

  1. The user "connects" by pushing the button.
  2. Sets a cookie on the Facebook browser, which your app backend reads to determine if the user is certified or not. After this, you associate this FB-cookie-AD with the user in your system.

If your system does not check for IP , then theoretically using cookies allows you to enter the application that uses Facebook Connect. You can then get access to the application,

Is it valid to say that you should check the IP when connecting Facebook to add security level? But if you do this, then some people have commented about IP spoofing.

@ All who say "physical access":

Yes, I agree that the concept of physical access makes this question trivial, though it is a hole about APPLICATION. Should be aware in Of course, the Facebook profile / useless application will not keep much ... but what if the application was a banking system? All I'm saying is that if Citibank or Bank of America has used "Facebook Connect" (which would be stupid but we assume), then this method would prove to be an easy way to access their account.

Therefore, Facebook Connect should not be used with "important" right?

Another option is that, after your friend goes to the bathroom, you can steal your wallet To give bribe to your girlfriend, you have cash in giving your Facebook password, thus, all of the applications that use Facebook Connect are projected.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
