  • General type of mail configuration: Internet Site
  • Create directories for web-based administration: No 
  • System Mail Name: ubb01.mydomain.local (Enter Your FQDN Name from part 1)

After installation we need to change a few settings.

  • Comment out bind-address in /etc/mysql/my.cnf with a text editor or open a terminal and do it with sed:
sudo sed 's/bind-address/#bind-address/g' /etc/mysql/my.cnf > /tmp/.my.conf
sudo mv /etc/mysql/my.cnf /etc/mysql/my.cnf.backup
sudo mv /tmp/.my.conf /etc/mysql/my.cnf
  • Then restart MySQL
sudo service mysql restart
  • Set Mail Domain name and Fix Courier SSL certificates by first deleting the old default certificates.
cd /etc/courier
sudo rm -f /etc/courier/imapd.pem
sudo rm -f /etc/courier/pop3d.pem
  • Then change the mail host name
sudo sed 's/CN=localhost/CN=ubb01.mydomain.local/g' /etc/courier/imapd.cnf > /tmp/.imapd.conf
sudo mv /etc/courier/imapd.cnf /etc/courier/imapd.cnf.backup
sudo mv /tmp/.imapd.conf /etc/courier/imapd.cnf
sudo sed 's/CN=localhost/CN=ubb01.mydomain.local/g' /etc/courier/pop3d.cnf > /tmp/.pop3d.conf
sudo mv /etc/courier/pop3d.cnf /etc/courier/pop3d.cnf.backup
sudo mv /tmp/.pop3d.conf /etc/courier/pop3d.cnf
  • Then create new mail SSL certificates
sudo su
service courier-imap-ssl restart
service courier-pop-ssl restart

16. Install AntiVirus and AntiSpam

Open a terminal window and enter:

sudo apt-get install amavisd-new spamassassin clamav clamav-daemon zoo unzip bzip2 arj nomarch lzop cabextract apt-listchanges libnet-ldap-perl libauthen-sasl-perl clamav-docs daemon libio-string-perl libio-socket-ssl-perl libnet-ident-perl zip libnet-dns-perl 
  • We can stop spamassassin as amavisd loads this internally.
  • Open a Terminal Window and enter the following :
sudo service spamassassin stop
sudo update-rc.d -f spamassassin remove

17. Install Webserver - Apache | PHP | PHPMyAdmin

TLSVerifyClient            off
TLSRequired                off
  • Restart ProFTP Server
sudo service proftpd restart

19. Enable and configure Firewall - ufw

  • ufw firewall is installed by default on Ubuntu 12.04.
  • gufw is a handy GUI frontends for ufw to manage the firewall.
  • Install on your system by opening a terminal windows and enter:
sudo apt-get install ufw gufw
  • Then enabe ufw. Open a terminal window and enter :
sudo ufw enable
  • Then open ports for various servers and services running on the server.
  • Enter one at a time from a terminal window to add the rules, or use gufw to open the ports :
sudo ufw allow 21/tcp    # ftp
sudo ufw allow 22/tcp    # ssh
sudo ufw allow 25/tcp    # smtp
sudo ufw allow 53/tcp    # domain
sudo ufw allow 80/tcp    # http
sudo ufw allow 110/tcp   # pop3
sudo ufw allow 139/tcp   # netbios-ssn samba
sudo ufw allow 143/tcp   # imap

sudo ufw allow 10024/tcp # smtp amavis
sudo ufw allow 11211/tcp # memcached
sudo ufw allow 20000/tcp # http-proxy 
  • After reboot make sure that ufw is loaded. Open a terminal window and enter :
sudo ufw status

20. Install Groupware Email Contacts and Calander - SOGo

  • SOGo is a very impressive open source groupware project, with many features and options to enable mail, contact and calendar sharing support. 
  • Complete setup of SOGo currently falls beyond the scope of this guide due to the vast configuration options available.
  • The installation instructions presented here are very specific for using MySQL as database for SOGo and as an User Source.
  • Complete documentation available on the SOGo website. And this good SOGo Debian Wiki guide which these instructions are based on. 

  • Start by adding the software source and install. Open a terminal window and enter:
sudo apt-key adv --keyserver --recv-key 0x810273C4
sudo su
echo "deb precise precise" >> /etc/apt/sources.list
sudo apt-get update
sudo apt-get install sogo sope4.9-gdl1-mysql memcached rpl
  • Ignore all installation errors and fix some things with the commands below:
sudo rpl 'SHOWWARNING=true' 'SHOWWARNING=false' /etc/tmpreaper.conf # suppress tmpreaper warnings
sudo rpl '' localhost /etc/memcached.conf # Fix IPv6 errors
sudo service mysql restart 
sudo service memcached restart 
  • Setup the SOGo MySQL database and add some demo users. Change sogopasswd for your sogo user password:
sudo mysql -u root -p mysql
mysql> CREATE USER 'sogo'@'localhost' IDENTIFIED BY 'sogopasswd';
mysql> GRANT ALL PRIVILEGES ON `sogo`.* TO 'sogo'@'localhost' WITH GRANT OPTION;
mysql> USE sogo;
mysql> CREATE TABLE sogo_users (c_uid VARCHAR(60) PRIMARY KEY, c_name VARCHAR(60), c_password VARCHAR(32), c_cn VARCHAR(128), mail VARCHAR(128));
mysql> INSERT INTO sogo_users VALUES ('paul', 'paul', MD5('zxc'), 'Paul Example', '');
mysql> INSERT INTO sogo_users VALUES ('piet', 'piet', MD5('zxc'), 'Piet Jansen', '');
mysql> quit
  • Add Apache modules:
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod headers
sudo a2enmod rewrite
  • Restart Apache
sudo service apache2 restart
  • Create the SOGo Configuration File changing details according to your setup.
  • After entering the configuration settings below the complete SOGo configuration file, is located in /home/sogo/GNUstep/Defaults/.GNUstepDefaults
sudo su sogo 
defaults write sogod SOGoTimeZone "Africa/Johannesburg"
defaults write sogod SOGoMailDomain "mydomain.local"
defaults write sogod SOGoLanguage English

defaults write sogod OCSSessionsFolderURL "mysql://sogo:sogopasswd@"
# Set MySQL authentication Usersources
defaults write sogod SOGoUserSources '({canAuthenticate = YES; 
  displayName = "SOGo Users"; 
  id = users; 
  isAddressBook = YES; 
  type = sql; 
  userPasswordAlgorithm = md5; 
  viewURL ="mysql://sogo:sogopasswd@";
# Use SMTP

#IMAP config
defaults write sogod SOGoDraftsFolderName Drafts
defaults write sogod SOGoSentFolderName Sent
defaults write sogod SOGoTrashFolderName Trash
defaults write sogod SOGoIMAPServer localhost

  • Restart SOGo
sudo service sogo restart
  • Create new Virtual Host for SOGo and remove SOGo.conf
sudo mv /etc/apache2/conf.d/SOGo.conf /etc/apache2/conf.d/SOGo.conf-backup
sudo su
echo "# disabled" >> /etc/apache2/conf.d/SOGo.conf
  • Create a new sogo.mydomain.local virtualhost file:
sudo gedit /etc/apache2/sites-available/sogo.mydomain.local 

Then add the following and save.

<VirtualHost *:80>
   ServerName sogo.mydomain.local
   ServerAlias sogo.local
   DocumentRoot /usr/lib/GNUstep/SOGo/WebServerResources/
   ErrorLog /var/log/apache2/error.log

   Customlog /var/log/apache2/access.log combined
  • Enable the new virtualhost in Apache and restart webserver:
sudo a2ensite sogo.mydomain.local
sudo service apache2 restart
  • You should be able to login to SOGo web interface with you demo users credentials.
  • Open a browser and go to:
http://ubb01.mydomain.local/SOGo OR http://sogo.mydomain.local/SOGo 

21. Install Virtualization - Oracle VM VirtualBox

  • Virtualbox will allow you to install and run virtual operating systems on the server.
  • This provides support for multiple operating systems and legacy software running on a single server. 
  • 4GB of RAM or more is advised if this is used as an option on your server install. 2GB of RAM per operating system is a rough guess to make things work smoothly.
  • Download and install the latest version of VirtualBox directly from the website.
  • Open a Terminal Window and enter the following :
sudo su
echo "deb precise contrib" >> /etc/apt/sources.list
wget -q -O- | sudo apt-key add -
sudo apt-get update
sudo apt-get install linux-headers-$(uname -r) build-essential virtualbox-4.3 dkms
  • Install the latest VirtualBox Extension Pack
cd /tmp
sudo VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.10-93012.vbox-extpack
sudo rm Oracle_VM_VirtualBox_Extension_Pack-4.3.10-93012.vbox-extpack

22. Install and configure Remote Desktop - x11vnc

  • The default Remote Desktop Server in Ubuntu 12.04 is Vino. This is not ideal for remote administration as it does not provide the security features needed.
  • We will install and configure x11vnc as our VNC server. This provides us with basic password as well as SSH tunneling and SSL security options.
  • This setup will allow administrators to log in remotely via all popular VNC viewers on Linux, Windows, Mac, iPad, iPhone and Android
  • Programs tested and supported : Vinagre, vncviewer, TightVNC, UltraVNC, Chicken of the VNC.

  • Install x11vnc and VNC viewers by opening a terminal window and entering:
sudo apt-get install x11vnc vinagre vncviewer
  • Create a x11vnc password file
sudo mkdir /etc/x11vnc
sudo x11vnc -storepasswd /etc/x11vnc/x11vnc.pass
  • Add a new lightdm startup configuration file so that  x11vnc server is loaded at startup.
sudo gedit /etc/init/x11vnc.conf 
  • Then add the following and save.
start on login-session-start
x11vnc -rfbauth /etc/x11vnc/x11vnc.pass -rfbport 5900 -display :0 -auth /var/run/lightdm/root/:0 -forever -bg -o /var/log/x11vnc.log -noxrecord -noxfixes -noxdamage -nomodtweak
end script
  • After reboot you will be able to log into the VNC server on:
Port    : 5900
Display : 0
Host    : ubb01.local (or your server IP address or hostname)
  • You can remove '-rfbauth /etc/x11vnc/x11vnc.pass' setting in the script above and will be able to log in but without a vnc password as security.
  • You should be able to connect with your vnc viewer like Vinagre with : ubb01.local:0 or ubb01.local:5900 or via your FQDN at ubb01.mydomain.local:0 or ubb01.mydomain.local:5900
  • You will also be able to securely connect using SSH tunneling specifying the tunneling host as localhost
  • You can do this in Ubuntu with vncviewer with the via command : 
vncviewer -via user@host locahost:0
  • In our example you will be able to connect as administrator to the server from another Ubuntu client machine (vncviewer installed) with
vncviewer -via administrator@ubb01.local localhost:0

23. Install VPN - LogMeIn Hamachi | Haguichi

24. Install Instant Messaging and VOIP Server - Openfire | Spark 

25. Backups - Ubuntu One | Déjà Dup

  • Ubuntu One and Deja Dup is installed by default in Ubuntu 12.04.

  • Ubuntu One is an excellent cloud backup, storage and sharing solution for small and medium sized business using a mixture of platforms and devices.
  • Ubuntu One supports Ubuntu, Windows, Mac OSX, iPhone, iPad and Android.
  • To get started on Ubuntu - Click on the Ubuntu One icon on your desktop to create an account and get 5GB free cloud backup storage.
  • To setup automated backups you can follow this excellent guide on How to Back Up Ubuntu the Easy Way with Déjà Dup
  • Tip: You can only backup the shared Ubuntu One folder in your Home direcotry or files owned by the current logged in user to Ubuntu One. So if you need to backup other users files and folders, use Duplicity and Cron Jobs to create encrypted, incremental backups of all files and folders to the Ubuntu One folder and Sync.
  • Tip: You can also use Ubuntu One Headless to set up Ubuntu One from the command line.


26. Server Security 




Hi. Thanks for a great

Hi. Thanks for a great tutorial. I had a great deal of trouble with another cookbook for SOGo, and this is much more straightforward. I encountered one big problem I haven't yet been able to solve, though. When I reached the point of populating the GNUstep defaults, the command "sudo su sogo" produced an error message that the user "sogo" is not available at present. From what I can gather, this might be a glitch caused by "sogo" being changed from a user to a daemon in later version of SOGo, but that's a very inexpert opinion. Anyway, that prevents me using the "defaults" command to create the .GNUstepDefaults file under /home/sogo/GNUstep/Defaults as indicated in your tutorial. I tried creating it elsewhere and moving it there, but SOGo doesn't seem to load this list of defaults on startup and I therefore can't access any user accounts. Have you encountered this, and can you recommend a workaround? Thanks again for the great tutorial. LDH

Hi, same problem here. A

Hi, same problem here. A workaround would be great! Thanks for the good work!

i found adding sudo -u sogo

i found adding sudo -u sogo then command worked sudo -u sogo defaults write sogod SOGoTimeZone "Europe/London"

what is the sogo admin

what is the sogo admin password? cant see what the default one is anywhere

See sogopasswd in

See sogopasswd in instructions for setting sogo admin password.

You can do it by adding sudo

You can do it by adding sudo -u sogo to each line or as per instructions you can become the sogo user by using sudo su sogo and issue commands as the sogo user.

My name is Ronald. Am new here. Am getting a lot of help from this forum.


Hi, great tutorial! After some tweaking everything works as a charm, and now our 10 man company has shared calendars, a network storage, SugarCRM for CRM and Frepple for production planning. I added hostapd to the system and we now also have a secure Wifi access point from the same server. The HW is an old laptop running Lubuntu 12.04 with an i5 CPU. It just works! Backup to Ubuntu One needs some alternative as Ubuntu One is now defunct. I plan to do an incremental backup of alla databases using mutt to gmail. Any other good ideas? Thanks for a really good tutorial and the effort you have put in this. This is exactly what a SME in our situation needed. Timo
