Criptografia simétrica e assimétrica. Sabe a diferença?

the difference between include and require in php

The documentation below also applies to require(). The two constructs are identical in every way except how they handle failure. include() produces a Warning while require() results in a Fatal Error.

Remote MySQL Access

GRANT ALL ON *.* TO root@192.168.1.1   IDENTIFIED BY 'palavra-pass'   WITH GRANT OPTION;
FLUSH PRIVILEGES;
We just have to tell Mysql to allow remote logins.
sudo vi /etc/mysql/my.cnf
Out-of-the-box, MySQL only allows connections from the localhost identified by the IP Address of 127.0.0.1.
We need to remove that restriction, so find the line that says
bind-address = 127.0.0.1


netstat -tupan | grep mysql

Recursively delete .svn directories

$ rm -rf 'find . -type d -name .svn'

or

find . -iname ".svn" -print0 | xargs -0 rm -r

Install subversion in ubuntu 10.10

First start off by installing Apache:

sudo apt-get install apache2

Enter the root password and follow the instructions. Check that is it installed correctly by going to http://localhost and checking that you see the standard Apache "It works!" message. Then install subversion and the subversion Apache module:

sudo apt-get install subversion libapache2-svn

Then create a directory to store repositories in:

sudo mkdir /var/svn/
sudo mkdir /var/svn/repositories

and create a test repository:

sudo svnadmin create /var/svn/repositories/test

So that Apache can read and write the repository its user (www-data) needs to be given ownership of it:

sudo chown -R www-data:www-data /var/svn/repositories/test

To be able to authenticate users who access the repository a password file is needed:

sudo htpasswd -c /etc/subversion/passwd paul

Enter a password for the user paul. For additional users repeat the command without the -c option to make sure the existing file is appended to rather than replaced.
Then edit the Apache config file:

sudo gedit /etc/apache2/apache2.conf

Add the following to the end of the file:

#svn users
<Location /svn>
     DAV svn
     SVNParentPath /var/svn/repositories/
     SVNListParentPath On
     AuthType Basic
     AuthName "Test"
     AuthUserFile /etc/subversion/passwd
     <LimitExcept GET PROPFIND OPTIONS REPORT>
        Require valid-user
     </LimitExcept>
  </Location>

 

Save the config file and restart Apache:

sudo /etc/init.d/apache2 restart

The Test repository can now be accessed via

http://localhost/svn/test
