How to install an FTP server on Ubuntu server 12.04

The idea of this blog post is to show how to install and configure a secure FTP access to your server and provide support for your users.

I'm configuring it so all you users can have their /home/{username} directory available as their FTP folder(s) which I think is one of the most secure ways of configuring an FTP service. After following this tutorial you can create a "ftp" user in your system without ssh access (you can google that ;) ) and use it as you generic ftp user. First of all we need to download the FTP server, in this case I'm going to be using VSFTPD, in order to download it, we need to add the ppa to our system by issuing the following commands:

# sudo add-apt-repository ppa:thefrontiergroup/vsftpd sudo apt-get update

and then install the package:

# sudo apt-get install vsftpd

Apache's ReverseProxy on Ubuntu

Sometimes you may find the need to shutdown a site for any reason an a specific server, basically the server that is listening to the web, so of course you will always want to keep that site(s) up and running while you perform whatever is needed on it, let's call it, 'external server', on a different environment, 'internal server'.
To do so you need to use an apache module called mod_proxy which enables a web server act as a router of traffic to another server, a tunnel.

- Enable mod_proxy and mod_proxy_http mod_proxy_html on external server
- create a virtual host on internal server pointing to internal server, ex:

<VirtualHost *:80>
    ServerName proxy.example.net
    ProxyRequests Off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass / http://proxy.…

Troubleshooting Zend Server CE on Ubuntu

Sometimes when updating or upgrading different packages on your Ubuntu specially kernel updates, Zend Server tends to break up and the whole packages system too, you usually get errors like "bad inconsistency" of package php-zend-server-ce-php-5.x and you are asked by the system to reinstall this package but that's also impossible due to the changes the update has performed.
In order to fix this issue try following the next steps:

    sudo /usr/local/zend/bin/zendctl.sh stop   => stop zend server service
    sudo rm -rfv /usr/local/zend/tmp/*            => remove zend server's cache and/or temp files
    sudo /usr/local/zend/bin/zendctl.sh start  => start the service again

and reinstall the zend-server-ce-php-5.x package using synaptic, or dpkg.
Hope this helps!
