How To Install Zimbra Collaboration Suite (ZCS) On Ubuntu
Version 1.0
Author: Falko Timme
Author: Falko Timme
This guide shows how to install the Zimbra Collaboration Suite (ZCS) on Ubuntu 6.10 (Edgy Eft) and 6.06 (Dapper Drake) server systems. Zimbra is a full-featured, open source collaboration suite - email, group calendaring, contacts, and web document management and authoring. It has a feature-rich AJAX web interface and is compatible with clients such as Microsoft Outlook, Apple Mail, and Novell Evolution so that mail, contacts, and calendar items can be synchronised from these to the ZCS server. It can also be synchronized to many mobile devices. ZCS makes use of many existing open source projects such as Postfix, MySQL, and OpenLDAP.
I do not issue any guarantee that this will work for you!
1 Preliminary Note
Please download the Ubuntu 6.10 or 6.06 server CD from http://www.ubuntu.com/download and install a basic Ubuntu system with it. Don't install/enable any services (e.g. like LAMP or DNS) - if you do, you'll have to disable them later on as they might interfere with Zimbra!
After the installation of the base system, we'll do some additional configuration, e.g. enable the root account, install an SSH daemon, apply a static IP address and a hostname to the system.
I will use the hostname mail.example.com in this tutorial together with the IP address 192.168.0.110. Adjust this to your needs, but make sure that mail.example.com has a valid MX record in DNS (Zimbra needs this!). I assume you want to create email accounts for example.com instead of mail.example.com, so you should have an MX record for example.com as well.
In this example the Zimbra server is in a local network (192.168.0.110 is a private IP address) behind a router, so make sure you use the router's public IP address (1.2.3.4 in this example) in the DNS records - of course this IP address should be static. If you have a dynamic IP address, you could use a service such as DynDNS.org, but keep in mind that most public IP addresses are blacklisted nowadays.
So if you use BIND on the authoritative name server for example.com, you should have something like this in example.com's zone file:
If your Ubuntu server is behind router, make sure that you forward at least port 25 from your router to your Ubuntu server.
If your Ubuntu server is in a data center, it most likely has a static public IP address and a hostname, so you can skip chapter 1.3, but still you must make sure that this hostname has a valid MX record.
1.1 Enable The root Account
To enable the root account, run
and specify a password for root.

Afterwards, become root by running
All following commands in this tutorial are executed as root (unless something else is written)!
1.2 Install The SSH Daemon
Just run
to install the SSH daemon.
1.3 Apply A Static IP Address And Hostname
Edit /etc/network/interfaces and adjust it to your needs (in this example setup I will use the IP address 192.168.0.110):
![Installation Installation](/uploads/1/2/4/7/124705325/257075176.jpg)
Then restart your network:
Then edit /etc/hosts. Make it look like this:
Now run
and reboot the system:
Afterwards, run
hostname
hostname -f
hostname -f
Both should show mail.example.com.
From now on you can use an SSH client such as PuTTY and connect from your workstation to your Ubuntu server and follow the remaining steps from this tutorial.
1.4 Disable The Ubuntu CD In /etc/apt/sources.list
I like to install all packages over the internet instead of from the Ubuntu CD, therefore I disable the Ubuntu CD in /etc/apt/sources.list now:
On Ubuntu 6.10 ('Edgy Eft'), comment out this line:
On Ubuntu 6.06 ('Dapper Drake'), it's this line:
Then update the packages database by running
1.5 Disable Services
If this is no fresh system and you have some services already running (such as Postfix, Apache, OpenLDAP), you must disable them first before installing Zimbra. Otherwise Zimbra will fail to install.
For example, to disable Postfix on your system, run
/etc/init.d/postfix stop
update-rc.d -f postfix remove
update-rc.d -f postfix remove
The commands for the other services are similar.
Note: Due to the USB 3.0 translation layer between native hardware and virtual machine, the librealsense team does not support installation in a VM. If you do choose to try it, we recommend using VMware Workstation Player, and not Oracle VirtualBox for proper emulation of the USB3 controller.
Please ensure to work with the supported Kernel versions listed here and verify that the kernel is updated properly according to the instructions.

Ubuntu Build Dependencies
![Ubuntu Ubuntu](/uploads/1/2/4/7/124705325/162226910.png)
The scripts and commands below invoke
wget, git, add-apt-repository
which may be blocked by router settings or a firewall. Infrequently, apt-get mirrors or repositories may also timeout. For librealsense users behind an enterprise firewall, configuring the system-wide Ubuntu proxy generally resolves most timeout issues.Prerequisites
Important: Running RealSense Depth Cameras on Linux requires patching and inserting modified kernel drivers. Some OEM/Vendors choose to lock the kernel for modifications. Unlocking this capability may requires to modify BIOS settings
Make Ubuntu Up-to-date:
- Update Ubuntu distribution, including getting the latest stable kernel:
sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
Note: On stock Ubuntu 14 LTS systems and Kernel prior to 4.4.0-04 the standard
It is recommended to upgrade the distribution with:
apt-get upgrade
command is not sufficient to bring the distribution to the latest recommended baseline.It is recommended to upgrade the distribution with:
sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial
- Update OS Boot and reboot to enforce the correct kernel selection with
sudo update-grub && sudo reboot
- Interrupt the boot process at Grub2 Boot Menu -> 'Advanced Options for Ubuntu' and select the kernel version installed in the previous step. Press and hold SHIFT if the Boot menu is not presented.
- Complete the boot, login and verify that a supported kernel version (4.[4,8,10,13,15,16]]) is in place with
uname -r
Download/Clone librealsense github repository:
- Get librealsense sources in one of the following ways:
- Download the complete source tree with git
git clone https://github.com/IntelRealSense/librealsense.git
- Download and unzip the latest stable version from
master
branch:https://github.com/IntelRealSense/librealsense/archive/master.zip
Prepare Linux Backend and the Dev. Environment:
- Navigate to librealsense root directory to run the following scripts.
Unplug any connected Intel RealSense camera. - Install the core packages required to build librealsense binaries and the affected kernel modules:
sudo apt-get install git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev
Distribution-specific packages:- Ubuntu 14 or when running of Ubuntu 16.04 live-disk:
sudo apt-get install
./scripts/install_glfw3.sh
- Ubuntu 16:
sudo apt-get install libglfw3-dev
- Ubuntu 18:
sudo apt-get install libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev
Cmake Note: certain librealsense CMAKE flags (e.g. CUDA) require version 3.8+ which is currently not made available via apt manager for Ubuntu LTS.
Go to the official CMake site to download and install the application

- Run Intel Realsense permissions script located from librealsense root directory:
./scripts/setup_udev_rules.sh
- Build and apply patched kernel modules for:
* Ubuntu 14/16/18 with LTS kernelscript will download, patch and build realsense-affected kernel modules (drivers).
Then it will attempt to insert the patched module instead of the active one. If failedthe original uvc modules will be restored../scripts/patch-realsense-ubuntu-lts.sh
* Ubuntu with Kernel 4.16./scripts/patch-ubuntu-kernel-4.16.sh
* Intel® Joule™ with UbuntuBased on the custom kernel provided by Canonical Ltd../scripts/patch-realsense-ubuntu-xenial-joule.sh
- Arch-based distributions
- Install the base-devel package group.
- Install the matching linux-headers as well (i.e.: linux-lts-headers for the linux-lts kernel).
- Navigate to the scripts folder
cd ./scripts/
- Then run the following script to patch the uvc module:
./patch-arch.sh
- Odroid XU4 with Ubuntu 16.04 4.14 imageBased on the custom kernel provided by Hardkernel
./scripts/patch-realsense-ubuntu-odroid.sh
Some additional details on the Odroid installation can also be found in installation_odroid.md
Check the patched modules installation by examining the generated log as well as inspecting the latest entries in kernel log:
The log should indicate that a new uvcvideo driver has been registered.
Refer to Troubleshooting in case of errors/warning reports.
sudo dmesg | tail -n 50
The log should indicate that a new uvcvideo driver has been registered.
Refer to Troubleshooting in case of errors/warning reports.
- TM1-specific:
- Tracking Module requires hid_sensor_custom kernel module to operate properly.Due to TM1's power-up sequence constrains, this driver is required to be loaded during boot for the HW to be properly initialized.
In order to accomplish this add the driver's name hid_sensor_custom to/etc/modules
file, eg:

- On Ubuntu 14.04, update your build toolchain to gcc-5:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-5 g++-5
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5
sudo update-alternatives --set gcc '/usr/bin/gcc-5'
You can check the gcc version by typing:gcc -v
If everything went fine you should see gcc 5.0.0. - Navigate to librealsense root directory and run
mkdir build && cd build
- Run CMake:
cmake ./
- The default build is set to produce the core shared object and unit-tests binaries in Debug mode. Use-DCMAKE_BUILD_TYPE=Release
to build with optimizations.cmake ./ -DBUILD_EXAMPLES=true
- Builds librealsense along with the demos and tutorialscmake ./ -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=false
- For systems without OpenGL or X11 build only textual examples
- Recompile and install librealsense binaries:
sudo make uninstall && make clean && make && sudo make install
The shared object will be installed in/usr/local/lib
, header files in/usr/local/include
.
The binary demos, tutorials and test files will be copied into/usr/local/bin
Tip: Usemake -jX
for parallel compilation, whereX
stands for the number of CPU cores available:sudo make uninstall && make clean && make **-j8** && sudo make install
This enhancement may significantly improve the build time. The side-effect, however, is that it may cause a low-end platform to hang randomly.
Note: Linux build configuration is presently configured to use the V4L2 backend by default.
Note: If you encounter the following error during compilationgcc: internal compiler error
it might indicate that you do not have enough memory or swap space on your machine. Try closing memory consuming applications, and if you are running inside a VM increase available RAM to at least 2 GB.
Note: You can find more information about the available configuration options on this wiki page.
- Install IDE (Optional):We use QtCreator as an IDE for Linux development on Ubuntu* Follow the link for QtCreator5 installation
