This is a draft version of the post. It’ll be revised.
Installing Ubuntu Server
- Download the latest version of Ubuntu Server. Note that it is not possible to convert Ubuntu 32 bit to 64 bit. The only way is to do a clean install.
- Create a bootable USB stick using Pen Drive Linux’s USB Installer.
- Boot up from USB and install Ubuntu Server. During the installation you can switch to terminal mode by pressing Alt+F2 and switch back by pressing Alt+F1.
Update the server:
aptitude update aptitude safe-upgrade
Installing and configuring FTP server on Ubuntu
Install FTP server:
apt-get install proftpd
To jail all users in their home directories uncomment line

in /etc/proftpd/proftpd.conf. To jail all but one users modify this line as follows:
DefaultRoot ~ !<user1>
note that there is a space after ‘~’.
How I configured sendmail for PHP on Ubuntu Server 12.04
Preventing sendmail from been very slow
The first thing that I did after installing sendmail with
aptitude install sendmail
is I put “gate.localhost” (gate is my server name) to /etc/hosts so it looks like this:
127.0.0.1 localhost.localdomain localhost 127.0.1.1 gate.localhost gate # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
With default /etc/hosts containing only “gate” and “localhost” sendmail hangs up for a while and writes to /var/log/mail.log the following message:
My unqualified host name (gate) unknown; sleeping for retry.
Securing Apache web server on Ubuntu Linux
Running Apache virtual hosts as different users
By default, Apache on Ubuntu executes all PHP scripts under www-data user, hence in situations where multiple mutually distrusting users have the possibility to put their PHP scripts on the server they could potentially spy on each other private data.
For example, the user user1 could put a PHP script that access file ‘file1.txt’ belonging to user2:
echo file_get_contents("/home/user2/www/file1.txt");
