[Update 11/2020] Omada SDN Controller 4.2.4 for Devuan, Debian and other Linux systems
First Version: 2020-07-15
Last Update: 2020-11-20
In good old tradition of the community version of Omada Controller I just re-packaged latest Omada SDN Controller 4.2.4 for installation on Devuan, Debian and any other Linux system providing the dpkg installer.
There have been massive changes in the omadactl script and I took the opportunity to re-introduce switching between controller versions as introduced with Omada SW Controller V2.7 years ago. This means that you can install Omada SDN Controller without overwriting your existing controller and you can switch between all installed versions on the fly w/o the need to downgrade. I think this is handy if you want to just preview Omada SDN Controller for now.
However, it has its price: Omada Controller V3.2.10 needs to be updated, too, if you want to use this feature. What's more, only V3.2.10 is supported for switching, but future versions of SDN Controller community version will support this function, too (for this to work the version number of the software package needed to be moved to the package name). This means that the old versions will not automatically be removed when installing a new version. You can manually remove the old version if the newly installed one runs to your satisfaction.
Standard Disclaimer
The community version contains the original Omada SDN Controller from TP-Link, but with Privilege Separation enabled by default, as well as omadactl, which is an enhanced shell script used to start/stop and to manage the Omada SDN Controller server process. For a full list of the differences between the community and the official version see the section at the end of this post. TP-Link only supports their official version of the controller, but naturally this will affect the controller software in this community version, too. As for omadactl, this shell script is supported by me (R1D2) and bugs are fixed when reported.
Note that I can not give any support for installation of the software on a particular Linux system.
Please don't ask for step-by-step instructions or even videos on how to install the software. Every information needed to install the software is described in this post. If you cannot manage to get the software running on your Linux system, consider use of the OC200 or OC300 controller, which both also use Linux, but hide the details of the software setup.
Prerequisites
There are a few things to consider before installing Omada SDN Controller:
- As usual, you need Oracle JRE8, jsvc, mongodb, netstat (package net-tools) and curl.
Make sure you have those utilities installed before installing Omada SDN Controller. See the notes below.
- Important: If you want to adopt your EAPs, you need to update their firmwares.
See the posts from TP-Link in this forum and the Omada Controller Upgrade Guide which is included in the Omada SDN Controller package as well as attached to this post for your convenience.
MongoDB database
Omada SDN controller requires at least mongodb V3.2 or newer. The following packages are known to work (note the different package names!):
OS |
Package name |
Version (dpkg) |
---|---|---|
Devuan ASCII |
mongodb |
3.2.11-2+deb9u1 |
Debian 8 |
mongodb-org |
3.2.22 |
Debian 8 |
mongodb-org |
3.6.22 |
Note that only mongodb V3.2 or mongodb-org V3.2 supports both, the old Omada Controller V3.2.10 and the new SDN Controller V4.
- On Devuan ASCII just install the package mongodb from the repository.
- On Debian and related distributions follow the installation instructions on mongodb.org for either V3.2.22 if you want to switch between Omada Controller versions:
https://docs.mongodb.com/v3.2/tutorial/install-mongodb-on-debian/
- If you want run only Omada SDN Controller and need no compatibility of mongodb with Omada Controller V3.2.10, install mongodb-org V3.6 (or higher):
https://docs.mongodb.com/v3.6/tutorial/install-mongodb-on-debian/
Java Runtime Environment
It's recommended to use Oracle JRE. Some platforms offer a package in their repository, others don't. I prefer to donwload JRE8 from Oracle's website directly and to use the update-alternatives(8) mechanism to install the latest version. This is how it works:
- Download the 64-bit JRE for Linux (you don't need the full JDK).
- Extract the TAR archive into a directory of your choice (e.g. /opt/jvm).
- Install the JRE using update-alternatives:
update-alternatives --install /usr/bin/java java /opt/jvm/jre1.8.0_261/bin/java 261
Over the time your installed JRE packages might look like this:
# update-alternatives --list java
/opt/jvm/jre1.8.0_171/bin/java
/opt/jvm/jre1.8.0_181/bin/java
/opt/jvm/jre1.8.0_251/bin/java
/opt/jvm/jre1.8.0_261/bin/java
#
You can configure the version to use with the command update-alternatives --config java.
See the manpage of update-alternatives for more information.
Commons Daemon (jsvc)
You can try to install jsvc from the repository of your Linux distribution. However, last time I checked on Debian 8 jsvc required OpenJDK, which – if being installed – will configure itself as the default JRE using the update-alternatives mechanism. In this case I recommend to download the jsvc source and compile it instead of installing it via apt/apt-get. The jsvc binary actually does not require the OpenJDK, just the package jsvc is contained in depends on OpenJDK for whatever reasons.
Now for Omada SDN Controller: donwload the all-architectures .deb package
- Download the SDN controller from https://rent-a-guru.de/ftp/omada-sdn-controller-4.2.4_1_all.deb. Note the new package name, which starting with v4.2.4 contains the version number as part of its name.
- While you're at it, download the update for V3.2.10 from https://rent-a-guru.de/ftp/omada-controller_3.2.10-3_all.deb if you want to use switching between controllers. You can either install this update before or after installing the SDN Controller (see also the above note about mongodb versions supported by both, Omada Controller V3.2.10 and SDN Controller V4).
- Compare the checksums of the downloaded .deb files for integrity:
$ md5sum -b omada-sdn-controller-4.2.4_1_all.deb
a1d825befbb126dd9b868058205078a0 *omada-sdn-controller-4.2.4_1_all.deb
or:
$ sha256sum -b omada-sdn-controller-4.2.4_1_all.deb
d8414d75597322ecb7ca57cb293dfdfe7343f4e60365f8a6e6da09788ecfa77a *omada-sdn-controller-4.2.4_1_all.deb
- For the Omada Controller V3.2.10-3 package update:
$ md5sum -b omada-controller_3.2.10-3_all.deb
6b986ee67828d4c1e55d8dc6af1e8cbc *omada-controller_3.2.10-3_all.deb
or:
$ sha256sum -b omada-controller_3.2.10-3_all.deb
ef77aa88a3196d7663f35e59357a67833b86fa783923df480f56318ea84e5de2 *omada-controller_3.2.10-3_all.deb
Installation
Since SDN Controller has a new package name, your existing Omada Controller will not be overwritten, so it will retain all data. Again, read the Omada Controller Upgrade Guide to migrate your existing site to the new controller if you desire so.
Installing the V3.2.10 package update will also keep all settings, but to be on the safe site, make a backup before installing it. Please note that copying the database from an old controller to the new SDN Controller does not work; you need to migrate your site if you want to see the settings in the new controller.
Optional step (can be left out or executed at a later time if you're in a hurry): upgrade Omada Controller V3.2.10 if you have installed it:
dpkg -i omada-controller_3.2.10-3_all.deb
Now install Omada SDN Controller with the following command:
dpkg -i omada-sdn-controller-4.2.4_1_all.deb
Note that installing this package will overwrite the files /usr/bin/omadactl, /etc/init.d/omadad and /etc/default/omadad in an existing V3.2.10 installation if you left out the optional step above. Due to changes in Omada SDN Controller the locations of those files needed to be changed, too. They are now contained in Omada Controller's home directory (/opt/tplink/OmadaController).
In order to allow different versions of the Omada SDN Controller installed at the same time, the version number is now part of the package name. For example, your list of installed controller versions might look like this:
$ dpkg -l | fgrep omada
ii omada-controller 3.2.10-3 all Omada Controller for TP-Link's ...
ii omada-sdn-controller 4.1.5-2 all Omada SDN Controller for ...
ii omada-sdn-controller-4.2.4 1 all Omada SDN Controller for ...
$
Version switching
Now for the switching part. Try the following command (you can shorten »version« to just »v«):
$ omadactl -l version
Currently installed versions:
EAP Controller 2.7.0
Omada Controller 3.2.10
Omada Controller 4.1.5
Omada Controller 4.2.4 (current)
$
Next, try the switch command (as root):
# omadactl stop
Stopping Omada SDN Controller
# omadactl switch 3.2.10
Switched to 'OmadaController-3.2.10'. Now restart Omada Controller to activate it.
# omadactl switch 4.2.4
Switched to 'OmadaController-4.2.4'. Now restart Omada Controller to activate it.
#
That's my way of doing »downgrades« in just no time.
Starting/stopping the controller
You can start the controller synchronously (option -w) or asynchronously (no option) with omadactl:
# omadactl -w start
Starting Omada SDN Controller .................................................................................................
Omada SDN Controller started successfully after 43 seconds.
Direct your browser to http://your_hostname:8088 for accessing Omada SDN Controller.
#
On my embedded system it needs ~94 to ~99 seconds to start, on my Debian server it needs ~43 seconds, YMMV. You can specify a timeout with option -W sec when starting the controller synchronously and you can set the default timeout permanently with option -S sec (w/o starting the controller). The default timeout has been raised to 120 seconds for the SDN controller. The initial setup of the database will require more time at the very first start of Omada Controller.
To stop the controller use the stop command. To show it's status use the status command (obvious, isn't it?):
# omadactl stop
Stopping Omada SDN Controller
# omadactl status
Omada SDN Controller is not running
# omadactl start
Starting Omada SDN Controller
# omadactl status
Omada SDN Controller is still initializing, please wait ...
#
The script /etc/init.d/omadad will start the controller asynchronously at boot time to avoid delaying the boot sequence. You could use this command to start or stop the controller, too, but omadactl gives you much more functions. See the manpage for more information.

More information
- For help with omadactl see its manpage: man omadactl
- For customization of omadactl see the config file CONFIG in the controller's home directory (/etc/default/omadad is gone).
- For a list of all files installed by the .deb package use the command: dpkg -L omada-controller
- If you want to uninstall this .deb package (except the database and other files created at run-time), use the »remove« option of dpkg: dpkg -r omada-controller
- If you want to uninstall this .deb package (including the database and other files created at run-time), use the »purge« option of dpkg: dpkg -P omada-controller
- For the release notes of Omada SDN Controller, the Omada Controller Upgrade Guide and the changelog for omadactl see the directory /usr/share/doc/omada-controller-4.1.5.
Differences and commonalities between official SDN Controller and Community Version (CV)
- The CV uses exactly the same JAVA class files from the official version, but is architecture-independend, that means it does not include any bundled binaries. Therefore you have to use up-to-date binaries for the required utilities which are most often installed on your Linux system anyway (curl, netstat, mongod, jsvc, java and a JRE of your choice). SDN Controller V4.1.5 finally removed previously bundled binaries as well as I always did suggest for its predecessors V2.x/V3.x.
- Official version 4.1.5 released 2020-07-13 has two bugs which prevent the controller from starting if Privilege Separation is used. If Privilege separation is not used, both bugs cause creation of a directory outside the Omada Controller's home directory with root ownership. Those bugs have been fixed in the CV already and have been reported to TP-Link.
- The CV automatically creates a role account »omadad« when installing the .deb-Package in order to enforce Privilege Separation, which is standard on UNIX/Linux for every server process started at boot time. To avoid the risk of potential root exploits you do not want to run the controller with admin privileges once it has been started.
- The CV uses improved shell scripts omadactl(8) and /etc/init.d/omadad for starting/stopping and managing the server. Both scripts replace the control.sh script found in the official version, which since version 3.x has incorporated a few critical, but not all mechanisms offered by omadactl.
- The CV's directory tree has much stricter file permissions which deny access for ordinary users to sensitive data such as certificates, properties, the controller's database and backups created with omadactl.
- The CV allows to have several controller versions installed at the same time and omadactl offers an easy way to switch between those instances on the fly.
- The CV uses the file CONFIG in Omada Controller's home directory for version- and system-dependend settings used by omadactl.
- omadactl allows to create backups from the command line using the mongodump(1) and mongorestore(1) utilities, thus enabling scheduled backups using the cron(8) daemon.
- omadactl allows to copy the database files from one version to another version, thus cloning the settings. Note: Direct database copies do not work for the transition from Omada Controller (V3) to Omada SDN Controller (V4).
- omadactl allows to raise or lower the Linux kernel's scheduling priority (niceness) for the Omada server process at start time or for an instance already running.
Enjoy! Sunshine!

Hey,
I am unable to download the Omada-Sdn-controller_4.1.5-2_all.deb file via FTP (I cannot switch to binary mode) and now my IP is banned from ftp. How can I do to recover the file? thank you in advance

@FrancoisNee, please do not use web-based FTP browsers. These browsers are absolutely lousy programmed, can't load files from read-only directories and hammer requests onto the FTP server as if this could compensate for the lousy programming.
Just use a standard Linux FTP command line client. Binary mode is selected automatically for binary files. FTP bans are temporarily, just wait somewhat before trying again.

Just an experience shared by me:
Got it running on a apu2d2 from PCengines. Which is a very small AMD64 board about twice the size of a RP3 but with 3 1Gbps ports. So very suitable as network device or firewall. (https://pcengines.ch/apu2d2.htm)
OS: Ubuntu 20.04.1 LTS Focal 64-bit
Mongod: Mongodb-org 3.6 64-bit
Java: openjdk-8-jdk-headless:amd64 8u265-b01-0ubuntu2~20.04
Omada SDN Controller: omada-sdn-controller_4.1.5-1_all.deb
Now the default version of JDK on this version of os is:
java -fullversion
openjdk full version "11.0.8+10-post-Ubuntu-0ubuntu120.04"
But I can't seem to get it running on that version. Mainly because jsvc doesnt like it.
Also mongodb is behind level 3.6 instead of 4.4 because I can't seem to get the level upgraded in the database. Still have to take a look on that.
I am using this repository for that:
echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list
I must say with this levels its working great.

@Ronald1965, I have it running on APU2 (and even Alix & APU1) series already since Omada Controller v2.7 (my preferred OS now is Devuan headless as a replacement for Debian).
Omada SDN Controller supports mongodb v3.0 to v3.6. It won't work with v4.4.

please check the name. It's omada-sdn-controller_4.1.5-2_all.deb, not Omada-Sdn-controller_4.1.5-2_all.deb. Note the lowercase characters!
Binary mode must work, it's standard mode for binary data.

@alpha-1, the recipe you posted is for installing the official TP-Link version which differs greatly in installation procedure from the community version. The community version is being installed using the Debian package installer dpkg, not using shell commands. Also, SDN Controller requires Oracle JRE8, not OpenJDK.
Sorry, I can't help with installing the official version – I do not install the controller this way on my systems.
What's more, Raspbian for RasPi4 is still compiled for armv7l 32 bit CPUs AFAIK, but required mongodb v3 supports only 64 bit operating systems.
You could try to run a docker image running Ubuntu on the Pi contributed by forum user Ronald1965 in post #8 in this thread.

Thx for your fast Answer. I can Imagine to use to Community Version. But my Linux skills are bad.
Do you have an simple fixed Image for me whitch i ony have to flash to SD Card?
Have an nice day

@alpha-1, sorry, there is no image, I don't use RasPi as a platform for SDN Controller.
Please see post #8 in this thread, there is a link to a docker image you can try.
It's much like an image, except that you install it under your Raspbian using docker.
